This research explores the condition and composition of the land-based labour market and the potential for scenario-based modelling to project future labour market requirements. The researchers conducted a review of literature and of statistical data, and a small number of stakeholder interviews.

Findings

  • Scotland’s national labour market has experienced a number of changes over the past few decades, including demographic ageing, advancing technological change and an increase in people with higher level skills.
  • The Covid-19 pandemic, EU exit and the net zero transition have also led to shifts in the labour market.
  • It is difficult to build a reliable picture of the composition of the land-based workforce in Scotland for several reasons, including a lack of formal definition of the land-based sector, a lack of consistency in the evidence collected for the sector and the reliance on unpaid and informal family labour.
  • The research revealed a partial picture of the current condition of the sector, particularly in rural locations. The analysis at local authority level showed:
    • The number of employees in the agriculture and forestry sectors increased between 2010 and 2021.
    • Recruitment, retention and labour shortages are a problem for employers in some rural areas.
    • Small numbers in rural areas make it challenging at sub-local authority level to explore the condition and size of the labour market.
    • Lack of access to affordable and appropriate public transport, childcare and housing may make it harder for rural employers to recruit employees and reduce the mobility of the rural workforce.
    • Rural areas tend to have higher proportions of small businesses and microbusinesses, which are likely to face challenges in ensuring that staff have access to relevant training and skills development as the labour market changes.

Executive summary

The Scottish Government’s 2020 Update to the Climate Change Plan 2018-32 recognises the need for large scale and rapid changes to the way we use and manage our land to help reach Scotland’s net zero targets. The Scottish Government is also committed to significant improvements in nature restoration, to tackle the twin crises of climate change and biodiversity loss.

Critical to delivery of these land use changes will be the size and skills of the workforce in land-based activities. In turn, the size and location of the workforce will be critical to the sustainability of many rural and island communities.

This report explores the condition and composition of the land-based labour market and the potential for scenario-based modelling to project future labour market requirements. We conducted a review of literature and of statistical data, and a small number of stakeholder interviews.

Key findings

Scotland’s national labour market, as in many other Organisation for Economic Co-operation and Development (OECD) countries, has experienced a number of changes over the past few decades, including demographic ageing, advancing technological change and an increase in people with higher level skills. The Covid-19 pandemic, EU exit and the net zero transition have also led to shifts in the labour market.

The composition of the land-based workforce

It is difficult to build a reliable picture of the composition of the land-based workforce in Scotland for several reasons:

  • There is no formal, widely accepted definition of the land-based sector, and therefore no clear, agreed set of Standard Industrial Classification (SIC) codes that describe it.
  • There is a lack of consistency in the evidence collected for the sector. It can be defined narrowly and traditionally to focus on primary agricultural production, or expanded to include food processing, or used much more broadly to include, for example, forestry and aquaculture.
  • The evidence base is mixed for the sectors that are usually regarded as making it up, with a substantial amount of information for the agriculture and forestry sectors, but much less detail for game and wildlife activities, peatland restoration and nature-based activities, with the latter term increasingly used but also poorly defined.
  • Commonly cited employment figures lack direct comparability, notably in forestry and agriculture, due to differences in the way that employment is measured, the breadth of industry definitions used and temporality.
  • Self-employed contractors, which are important across several kinds of land-based activities, may not be registered in formal statistics, particularly if they fall beneath the PAYE and/or VAT thresholds.
  • There is a reliance on unpaid and informal family labour, particularly in agriculture.

Accepting the above caveats, some of the most widely used recent workforce estimates are given in Table 1 below.

The current condition of the rural land-based labour market

The research revealed a partial picture of the current condition of the sector, particularly in rural locations. Our analysis at local authority level showed:

  • The number of employees in the agriculture and forestry sectors increased between 2010 and 2021. The greatest increase occurred in Mainly rural local authority areas. Within agriculture, the increase in the number of employees is offset by a decrease in the number of working owners, meaning that the agricultural workforce is roughly the same in 2021 as it was in 2010. Within agriculture, a substantial difference between the number of employees and number of full-time workers suggests the importance of part-time and seasonal employees in this sector.
  • Recruitment, retention and labour shortages are a problem for employers in some rural areas. Competition between sub-sectors may prove to be a challenge for employers in the short term, given the tightness of the current labour market. Evidence from stakeholder interviews suggests that competition already exists.
  • Small numbers in rural areas make it challenging at sub-local authority level to explore the condition and size of the labour market using the Scottish Government’s Urban Rural Classification.
  • Lack of access to affordable and appropriate public transport, childcare and housing may make it harder for rural employers to recruit employees and reduce the mobility of the rural workforce.
  • Rural areas tend to have higher proportions of small businesses and microbusinesses, which are likely to face challenges in ensuring that staff have access to relevant training and skills development as the labour market changes.

Conclusion

This project has explored the existing evidence base for the land-based sector’s labour market and revealed a very partial picture in terms of current knowledge and evidence, and therefore challenges in projecting future labour market requirements.

Actions to expand and improve both the coverage and the consistency of the quantitative and qualitative evidence base now will help to better understand the size, shape, location and seasonal patterns in the future land-based labour market. This improved understanding will inform decisions about future skills and training opportunities and wider infrastructure provision across Scotland’s rural and urban areas in order to deliver Scotland’s net zero-related land use targets.

These challenges in establishing a reliable picture of the current land-based workforce in Scotland mean that carrying out accurate modelling to understand the future size, scale and location of this workforce is difficult. Some recent studies, including by the Climate Change Committee (2023), have attempted to estimate the impacts on employment in different sectors from net zero-related land use change.

Introduction

The Scottish Government recognises the need for large-scale and rapid changes to the way land is managed to meet the country’s target of net zero by 2045 in its Climate Change Plan 2018-2032 Update (CCPU) published in 2020. Critical to the delivery of these changes are the size, skill levels and location of the workforce across rural and island communities, and indeed the sustainability of those communities themselves.

This report takes a system-wide overview of the existing statistics and what they tell us about the current land-based labour market. This informs the design of a potential methodology for scenario-based modelling work to understand future land-based labour market needs (more detailed information about the project’s aim, objectives, and the associated tasks and methodological approach adopted is provided in Appendix 1).

A number of different sector-specific and general policies and strategies form the context for this work, and there are close links between this project and the work of the Commission for the Land-Based Learning Review which reported in January 2023. The policy context demonstrates the importance of understanding the future land-based labour market but also that this is a complex area which is rapidly evolving. A brief introduction to this policy context can be found in Appendix 2, including detail on the CCPU policy targets.

Understanding the land-based workforce and associated skills

Defining the land-based labour market

It is critical to clearly define what is meant by the term ‘land based’, and in particular which sectors or economic activities are included – and which are not.

There is no ‘formal, official’ definition of the land-based sector, for example, by the Office for National Statistics in their Standard Industrial Classification (SIC) codes[1], and we found no significant discussion in the academic literature (see Appendix 3). However, several organisations in the employment, skills and training domain do (either explicitly or implicitly) provide definitions and/or explanations (which are not all consistent), such as Lantra, the National Land Based College, the SQA and other private training providers such as Pearson. These are summarised in Appendix 4.

The Commission for the Land Based Learning Review (CLBLR) was appointed by the Scottish Government to undertake a ‘root and branch’ review of learning in Scotland’s land-based and aquaculture sectors, from early years to adulthood. The Commission reported to Scottish Government in January 2023, and discussed (amongst a range of other issues) the need to reframe the land-based sectors to the nature-based sectors noting that:

“…the term land-based has long been used to collectively describe the range of different industries which use land and the marine environment to produce food and renewable resources. It has also encompassed what have in the past been seen as key supporting roles, such as engineering, equine and environmental conservation. Collectively these industries utilise and manage the majority of Scotland’s land and coastal areas, and have the largest impact on our environment. More recently, the land-based industries have been included within ‘Green Careers’ recognising the key role the Sector plays in nature restoration, climate change mitigation and adaptation.”

This means achieving an accurate and up-to-date understanding of the exact size, composition and location of the land-based workforce is difficult.

The availability of labour market data in Scotland

There is a wealth of labour market data for Scotland, but it is difficult to build a complete and accurate picture across sectors and geographies.

Data on the UK labour market as a whole, and on individual regions and devolved areas (including Scotland) and sectors, is available from a number of sources[2], with Skills Development Scotland’s (SDS) Regional Skills Assessments (RSA) and Sector Skills Assessments (SSA) particularly useful in providing data on all of the main sectors in the current and future labour market (more information on the data available can be found in Appendix 5).

However, in addition to the lack of a land-based definition, the activities that are usually regarded as being ‘land-based’ are not always easy to disaggregate from other activities (e.g. land-based engineering from other forms of engineering, and food and drink processing from wider manufacturing activities). It is also sometimes the case that, while the original data may be collected at national level broken down for SIC codes (e.g. through the BRES and the Census, for example), when that data is made publicly available, the SIC codes are combined, for example in SDS’s SSA for agriculture, forestry and fishing. Consequently, a detailed understanding of individual sectors may be hard to achieve.

Key challenges in understanding the land-based workforce

The labour market generally, and perhaps particularly for land-based sectors, is complex, and there are key factors that contribute to this complexity:

  • Many of those working in land-based activities, such as agriculture, forestry and peatland restoration, are self-employed and/or contractors running their own small or micro business, and so they may not show up in formal statistics. This may be the case, for example, if their business falls below the PAYE or VAT threshold and so does not show up in statistics which only include registered businesses.
  • ‘Official’ statistics on the size or composition of the rural economy therefore underestimate its true size and shape (for more discussion of this, see Section 2 in SRUC’s Rural Scotland in Focus 2016 report, for example). One way to gather information on these unregistered businesses is through HMRC data (tax return data for example) but this data is understandably difficult to access and to analyse for confidentiality reasons[3].
  • Not everyone will feature in the data – women and other family members may not always be visible in the statistics (perhaps because they work unpaid on-farm or in farm-related economic activities such as running linked accommodation or shops). Detailed research work has been carried out about women in the agricultural sector, including the 2017 report for Scottish Government for example, and by academic researchers[4].

For a variety of reasons, we do not have a clear, detailed understanding of the composition of the land-based labour market and its constituent parts. This means that it is difficult to plan for current and future workforce and skills needs, including in different geographical locations. This evidence base is critical to ensuring that the land-based sector can meet its net zero obligations and that appropriate skills and training provision, and wider housing, digital connectivity and transport infrastructure is in place to support employers and their workforce where it is required.

The current rural land-based labour market and key trends

Key characteristics

The Scottish Government’s ‘Understanding the Scottish Rural Economy’ report published in 2018 provided a useful summary, albeit from several years ago before the Covid-19 pandemic and EU exit, on the key characteristics of businesses and employment in rural Scotland. The report confirmed:

  • the relatively low proportion (4%) of Gross Value Added (GVA) in the islands and remote rural areas which is directly attributable to the Agriculture, Forestry and Fishing sector, with an even lower proportion (3%) in mainly rural Scotland (and 1.3% for Scotland as a whole).
  • the growth in GVA in Scotland as a whole since 1997, with the lowest growth observed in the Agriculture, Forestry and Fishing sector over this period.
  • the considerable variation in performance across Scotland’s rural local authorities with some experiencing employment growth and others not.
  • the tendency for unemployment rates to be generally lower in rural areas while employment and activity rates are higher, with part-time, seasonal, self-employment and multiple job-holding particularly prevalent in rural areas.

It is worth noting again here, however, the problem of combining Agriculture, Forestry and Fishing activities as all have had different growth trajectories in recent years. Forestry, for example, has experienced considerable growth in both scale and value since 1997, but that growth is often masked in the data by different trends in the other sectors.

Wider challenges that impact on the labour market

Wider structural challenges face many rural households and may impact on their ability to fully participate in the labour market now and in future. These include:

  • Their generally higher spending levels (than equivalent urban households), on food and fuel particularly (combined with lower wages and salaries, as explored in the Joseph Rowntree Foundation-led Minimum Income Standards work for example).
  • rural poverty being under-reported in official statistics.
  • poor, unreliable, infrequent and expensive public transport provision in many areas.
  • a shortage of appropriate and affordable housing for purchase and rent.
  • a lack of flexible and affordable childcare.

Housing is a significant and long-standing challenge in many rural and island communities, with poor affordability (both for purchase and rent) and low levels of supply due to a lower rate of new house building and high numbers of second and holiday homes. Rural dwellers, reliant on local, low wage employment, are often priced out of the local housing market. More information on all of these issues is provided in the recent Rural Lives report and in SRUC’s Rural and Island Insights Report 2023.

Evidence suggests more self-employment and part-time/seasonal working in Scotland’s rural communities. While at face value this may be taken as evidence of a flexible labour market with many ways for individuals to engage with work, and of high levels of entrepreneurship, rural and island dwellers are often reliant on multiple jobs through necessity rather than choice. The RSN’s 2021 Cultivating Rural Growth report examines this issue in more detail.

The significance of language – Scotland’s ‘green’ labour market

Terms such as ‘green transition’, ‘green skills’ and ‘green jobs’ have become more widely used to describe the changes required in labour markets to meet climate and environmental goals (such as implementing circular economy practices, enhancing biodiversity, etc.), and to ensure a sustainable recovery from the Covid-19 pandemic (see the Scottish Government’s Covid Recovery Strategy for example). As noted in SDS’s February 2022 SSA for the Agriculture, Forestry and Fishing sectors:

“green jobs are at the forefront of the Government’s plans for recovery. Demand for green jobs (and green skills) is expected to increase rapidly as a result of policy and legislative drivers and consumer choice.”

However, these terms remain poorly defined and there is no single agreed way to quantify them. This matters, because it influences how data is collected and the size, scale, location, gender breakdown, etc., of projections about future skills requirements.

Some approaches take a very narrow definition for green jobs, such as only including jobs that contribute substantially to preserving or restoring environmental quality. In contrast, broader definitions could potentially include all jobs on the basis that everyone has an obligation to take action to protect the environment and that there is a huge number of skills which will support the net zero transition. These different interpretations make it difficult to assess the current and likely future spatial distribution of the green labour market (for example, in terms of the spread of jobs between rural and urban areas) and thus the geographical variations in required skills and training provision. A detailed discussion of different definitions is provided in Appendix 6, along with information on the 2022 Green Jobs in Scotland report, Greensoc, the new green occupational definition, the Green Jobs Workforce Academy, and the UK Green Taxonomy which may provide greater clarity.

The Scottish Government has increasingly recognised the importance of green jobs and green skills to Scotland’s future labour market as the country recovers from the Covid-19 pandemic. However, without a clear definition of what is (or is not) included, it is hard to quantify where these jobs are, their type, pay and skill levels, in order that education and training providers and businesses and individuals can respond appropriately.

Recent trends in Scotland’s national labour market

Scotland’s national labour market, similar to other OECD countries, has been affected by a number of longer-term trends over recent years, including:

  • Demographic ageing
  • Technological advancement, including mechanisation
  • Robotisation and digitalisation (e.g. artificial intelligence, machine learning, etc.)
  • Changes in emerging markets at the global scale
  • Changing work-life preferences, including a shift to flexible and home-based working in some sectors
  • Changing land and housing values
  • Changing methods of education and training delivery
  • Circular economy, bioeconomy and net zero trends and targets.

In addition, there are a number of short-term shifts which have occurred more recently:

  • the Covid-19 pandemic, which has accelerated processes of digital transformation and increased levels of remote or hybrid working but has particularly benefited those in higher skilled, higher paid jobs.
  • the UK’s exit from the EU has led to changes in the availability of overseas workers in some land-based sectors, including agriculture.
  • there have been wider international economic and political shifts, including the war in Ukraine and the cost of living crisis, which have further impacted on supply chains, prices, labour markets and household decision-making (in relation to house purchasing for example).

It is likely that, in future, some sectors in the economy will see an increasing demand for workers and new skills required from both new workers and those already in employment who may be required to reskill or upskill. However, the ‘tight’ labour market, plus restrictions on workers coming in from overseas, raises concerns as to the extent to which the UK labour market (both rural and non-rural) may be in a position to flexibly respond to these new demands.

While the terms ‘green jobs’ and ‘green skills’ are being widely used internationally and in Scotland (see for example, Hirst and Lazarus’ work for NatureScot in 2020; and work by Ecuity Consulting for the Local Government Association in England projecting future green jobs requirements), they are not well defined (see Section 6.1.2).

Key activities in the land-based labour market

Much of the economic and employment data that is publicly available is at relatively large geographic scale (e.g. local authorities) mainly to protect the confidentiality of individuals and businesses, and often is not analysed for rural and urban differences. This makes it difficult to achieve a detailed understanding of the labour market in Scotland’s sub-regions and localities. Appendix 7 summarises some information on the rural labour market; more up-to-date information can be found in SRUC’s Rural and Island Insights Report 2023, published in August 2023 and in the Scottish Government’s Rural Scotland Data Dashboard and accompanying report which were published in December 2023.

We found very limited academic literature on the labour market in land-based sectors (see Appendix 3), with most information found in industry or government sources. Considerably more information was found for the largest sectors of agriculture (see Appendix 8) and forestry (see Appendix 9). We also found information relevant to the game and wildlife management sector (see Appendix 10) which, while not featured in the policy targets in the 2020 CCPU , is an important sector in terms of understanding current and future land use change. There is an emerging body of academic research and practitioner experience on peatland restoration and on nature-based activities (see Appendix 11).

Agriculture

Agriculture is the most significant land use in Scotland, with 80% of Scotland’s land mass under agricultural production. Employment in agriculture is a key component of the land-based labour market, particularly in rural areas. However, there are a number of different sources of data on the agricultural labour market collected by national statistical agencies and by sector-based organisations (by which the agriculture sector is well served[5]) and based on different ways of measuring employment (see Table 2). As a result, it is difficult to obtain a definitive clear, accurate picture of the size of this sector’s current labour market, as well as to make predictions for the future. The primary sources are set out here. Additional sources are detailed in Appendix 8.

  • The June 2021 Agricultural Census estimated the total agricultural workforce in Scotland to be around 67,400 workers[6] in 2021. One year earlier, the 2020 Agricultural Census estimated a total workforce of 66,700. In 2018, the number of people employed in agriculture was estimated at 67,000, accounting for 2.5% of the total number of people employed in Scotland, and around 8% of the total rural workforce.
  • According to NFUS, based on 2020 Agricultural Census data, agriculture is the third largest employer in rural Scotland after the service and public sectors. It is estimated that, in addition to the (just under) 67,000 direct employees, a further 360,000 jobs (1 in 10 of all Scottish jobs) are dependent on agriculture.
  • These estimates are somewhat lower than the data from the Business Register and Employment Survey (BRES) which estimated employment in two-digit SIC code 01: Crop and animal production to be 75,000 in Scotland in 2021.

The Scottish Government’s Rural Scotland Key Facts publication in 2021, based on data from the Inter Departmental Business Register from March 2020, described agriculture, forestry and fishing as accounting for 15% of the remote rural workforce and 12% of the accessible rural workforce in 2020 (0.5% in the rest of Scotland).

Figure 1 depicts data from the June Agricultural Census from 2011-2021. The Census data shows that the agricultural workforce is roughly the same in 2021 as it was in 2011, having declined from 67,800 in 2011, to 63,500 in 2016 (a 6% decrease), before recovering to 67,400 in 2021.

Working occupiers are highly significant to the workforce in agriculture and make up more than half of the total workforce. Nonetheless the workforce composition has shifted slightly between 2011 and 2021. While the total number of employees has increased by 7% over the period, driven by an increase in part-time staff (13%) and casual staff (15%), over the same period the number of working occupiers has decreased by 6%.

Data from the BRES shows a similar trend in terms of the overall size and composition of the workforce in agriculture. Figure 2 reports various measures of employment in the agricultural sector between 2010 and 2021 using the 2-digit SIC code (01: Crop and animal production, hunting and related service activities).

According to the BRES, mirroring the broad trend seen in the Agriculture Census data, between 2011 and 2021 total employment (including working owners)[8] declined from 70,000 in 2010 to 66,000 in 2016 before recovering to 75,000 in 2021. However, a slightly stronger trend is seen for the change in composition than in the Agricultural Census data. Measured by BRES, the number of agricultural employees increased by 21.43% from 2011 to 2021. This estimate is however somewhat sensitive to the choice of base year. For example, measured from 2010 to 2021, the increase is 13.33%.

Figure 3 below shows the strong rurality of employment in agriculture and depicts employment in relation to rural and urban local authorities using the Scottish Government’s RESAS 2018 rural-urban local authority classification: Larger cities, Urban with substantial rural areas, Mainly rural areas, and Islands and remote areas. Figure 3 demonstrates that the majority of agricultural employees are in the mainly rural local authority areas. The number increased from 21,250 persons in 2010 to 24,600 persons in 2021.

SDS’s SSA in 2022 reports a decline in the current workforce in the agriculture, forestry and fishing sectors of 11% between 2012 and 2019. Geographically the highest number of workers in these three sectors combined is in the Highlands and Islands, Tayside and the South of Scotland areas.

Based on data provided by SDS in their 2022 SSA for the Agriculture, Forestry and Fishing sectors, looking forward, in the 2022-2025 period, the number of people in employment in the Agriculture, Forestry and Fishing sector is forecast to grow by 1.1 per cent (400 people). This is a slightly smaller percentage growth than is forecast overall across Scotland where employment is predicted to rise by 1.2 per cent (31,900 people). Most of this growth will be in the skilled agricultural trade occupations. The forecasts for 2022-2025 suggest there will be 10,200 job openings in the sector due to some jobs growth and opportunities created as a result of the need to replace workers leaving the labour market due to retirement and other reasons (i.e. replacement demand). Whilst positive, caution is needed as a wide range of factors may impact the future labour market. At the time of writing the economic outlook is uncertain and labour shortages continue to be a dominant issue.

In terms of the longer-term (2025-2032), the short-term growth will cease and decline in employment is predicted by 2.6 per cent (-1,000 people) (to a level of 37,500 people in 2032). This is in contrast with employment growth forecast overall across Scotland where employment is predicted to rise by 1.5 per cent (40,700 people). It is also expected that there could be an ongoing requirement for skilled people to fill opportunities created by people leaving the labour market. Forecasts show that there will be 21,000 job openings in the long-term. This will be driven by the need to replace workers leaving the labour market in Agriculture, Forestry and Fishing (i.e. a predicted expansion demand of -1000 people, combined with a predicted replacement demand of 22,000 people creates a total requirement of 21,000 people).

Forestry

As is the case with agriculture, the forestry sector is also reasonably well served in terms of sector bodies of different kinds[9] and there is a substantial amount of information on employment and skills available through some of these organisations. Again however different approaches are taken to measuring the size and shape of the labour market. Employment figures for forestry are given in Table 3. Key points include:

  • A study by CJC Consulting in 2015 estimated that direct employment in the Scottish forestry and wood processing sector[10] was 12,143 FTE in 2012/13, total employment was 19,555 FTE, and GVA was £771 million.
  • Adopting a wider definition of the forestry sector that includes forest recreation and tourism,[11] Scotland’s Forestry Strategy 2019-29 reported that in 2015, Scottish forestry was estimated to contribute almost £1 billion to Scotland’s GVA and employed approximately 25,000 FTE (total employment).
  • Most recently, Forest Research’s (2022) Forestry Statistics note that direct employment in UK forestry in 2019 stood at 18,000 (with data taken from the BRES), with a further 7,400 employed in primary wood processing (based on industry survey data).
  • The Forestry Skills Action Plan produced by the Scottish Forest and Timber Technologies Group in 2020 builds on the 2015 data to note that the 25,000 FTEs employed in forestry at this time represented a reduction of 16% since 2014, due to rising productivity and/or an increase in self-employment.
  • The Action Plan notes the dominance of males amongst the forestry workforce (79%), and that the self-employment level is around 50%. It reports that the greatest number of forestry businesses are in the Highlands, the South of Scotland, Perthshire, Aberdeenshire and Argyll and Bute.
  • The Action Plan notes that the average salary for forestry workers (forest craftspersons, harvesters, tractor drivers) is currently £22,880 and £30,680 for forestry managers, although skilled harvesters can earn as much as £50,000.

Using publicly available data from the BRES, Figure 4 below shows Scottish employment in the forestry sector between 2010 and 2021. For most of the period, the number of employees has ranged around 3,000, although between 2020 and 2021 there was a rapid increase to 4,500. The majority of employees were in full-time employment, which increased from 2,500 in 2020 to 4,500 in 2021 (80%). The proportion of working owners within the workforce remained relatively stable and therefore total employment (employees and working owners) increased from 4,500 to 6,000 between 2020 and 2021 (50%)[14]. As this relates to a single year, more work would be required to be more confident of this trend.[15]

Mirroring the situation for agriculture, Figure 5 shows the strong rurality of employment in forestry and depicts the total number employed in relation to rural and urban local authorities using the Scottish Government’s RESAS 2018 Urban Rural Local Authority Classification. It demonstrates that the majority are in Mainly rural local authority areas, and that growth in employment has occurred in these areas where the number of employees increased by 44.75% between 2010 and 2021. Again, however, more work is needed to be confident that this represents a real trend.

Peatland restoration

Peatlands are a key part of the Scottish landscape, providing significant carbon storage potential, an internationally important habitat, a means of improving water quality and reducing flood risk, and highly attractive locations for tourism.

In contrast to agriculture and forestry, however, peatland restoration is not recognised as a discrete ‘sector’ in the way data is collected (i.e. the SIC codes used), nor does it have well-established representative sector organisations. It was not possible to find accurate and up-to-date data on the numbers of people currently employed in peatland restoration activities in Scotland. While there is growing academic work to understand the costs and effectiveness of peatland restoration (see for example, Glenk et al. 2022; Glenk and Martin-Ortega, 2018; Artz et al., 2019) and the motivations and experiences of actors (see for example Novo et al., (2021)) this work has yet to address current employment levels.[16]

The research team therefore sought to gather more qualitative information from short interviews with several individuals working in different capacities in the sector (see Appendix 1). The results emphasised that the restoration work itself involves a very wide range of occupations, knowledge, skills and equipment across different sites, partly dependent on their characteristics, location, altitude, topography, access, etc.

Peatland restoration work is primarily conducted by skilled machine operators. Most peatland restoration projects will require some form of designer as a main consultant, an ecologist and a project manager for the contractors who do the work. Some companies are exploring how to manage this work in-house but, in most circumstances, self-employed sub-contractors are used. Following initial restoration, maintenance and monitoring work may be required. Within the wider supply chain the skills/professions that are required include hydrologists, soil scientists, ecologists, conservationists, engineers, project managers, administrative staff, researchers, and manual workers of various kinds.

Nature-based activities

There is no single universally accepted definition of the nature-based sector. A report by Hirst and Lazarus in 2020 for NatureScot includes the following nature-based solutions in a broad definition of nature-based jobs:

  • Peatland restoration
  • Flood risk management
  • Blue carbon
  • Coastal ecosystems
  • Woodland restoration
  • Low carbon and regenerative land use including agriculture, forestry and wildlife management
  • Sustainable marine management and fisheries
  • Green finance
  • Urban green infrastructure, including planning, ecological engineering, active travel networks
  • Sectors highly dependent on natural capital (especially tourism and food and drink)

This broad definition is worth bearing in mind in relation to the CLBLR’s recent report which recommended consideration of using this alternative ‘label’ for the land-based sector.

Despite a thorough search by the research team, NatureScot appears to be the only organisation generating evidence about the contribution of and labour requirements for this sector. The 2020 report for NatureScot by Hirst and Lazarus is the most comprehensive study of the nature-based sector that could be found and this estimates that:

  • the sector makes a significant contribution to the Scottish economy, amounting to 195,000 jobs or 7.5% of Scotland’s workforce in 2019.
  • the number of jobs increased by 12,031 between 2015 and 2019 (a 7.5% increase), accounting for one-third (31.7%) of all job growth in Scotland during this period.
  • this growth rate was more than five times the rate of all jobs in Scotland in the period 2015-19.
  • this is also likely to be an under-estimate as some of the smallest businesses operating in the sector are likely to be unregistered. It is also difficult to separately identify the key nature-based sectors, and it is also possible that some nature-based activity is actually included in other sectors, such as construction (e.g. of water-based projects).
  • the majority of these jobs are in rural local authority areas, with 9% being Island and remote, 46% being Mainly rural, 24% being Urban with substantial rural, and 21% within Larger cities.

As shown in Table 4 below, Hirst and Lazarus (2020) build on the work of two earlier studies. Various definitions for nature based activities have been used resulting in a range of estimates for employment in the nature based sector (see Appendix 11). Notably, Biggar Economics (2020) include employment in oil and gas extraction which is excluded from other studies on the basis that it is not assessed as sustainable.

Table 4: Nature Based Jobs in Scotland

Employment estimate

Hirst and Lazarus (2020)

Biggar Economics (2020)

They estimate total employment in the natural sector as 290,100 in 2018, around 11% of Scottish employment.

RPA and Cambridge Econometrics (2008)

They estimate nature- based employment in Scotland in 2003 as 154,000 jobs directly supported by the natural environment or 242,000 when further considering direct, indirect and induced employment.

Looking ahead, Hirst and Lazarus (2020) argue that significant further growth is anticipated on the back of the expansion in activities – including peatland restoration, green infrastructure and green finance, woodland creation, and blue carbon – required to meet our net zero targets by 2030 and 2045. Several opportunities were identified for nature-based skills development by Hirst and Lazarus (2020), including a need to fill operational jobs more effectively, for which recruitment is often local and sometimes through sub-contracting arrangements. While graduate and post-graduate jobs were found to be relatively easy to fill, there were challenges with operational posts due to a lack of applicants, a lack of experienced candidates and competition for the same skills from other sectors.

Conclusion

While the evidence base for the agriculture and forestry workforce is relatively well developed, though not always consistent, that is not the case for the peatland restoration and nature-based sectors where the evidence base is limited.

This is mainly due to:

  • data-related issues (not least that these two sectors do not map easily onto existing SIC codes) which mean that activities are hard to identify and define clearly, and therefore hard to analyse and understand.
  • the nature of the workforce in many of these activities, again with a dominance of contractors and individuals working on a self-employed basis, who may travel around locations to access work opportunities.

There is potential for competition for individuals with relevant and transferable operational skills between sectors – for example between construction and some aspects of peatland restoration, and between peatland restoration and forestry, but it is difficult to ascertain the potential extent and impact of this competition from existing data. Moreover, the extent of this competition will also be affected by wage levels in different sectors, the geographical and seasonal distribution of jobs, ease of access to and the cost of transport in rural communities, access to appropriate and affordable housing, access to training and re-/up-skilling initiatives, etc. In future, gathering both qualitative and quantitative data on these issues will be hugely valuable to improving our understanding of the complexities of the land-based labour market and the issues that affect it.

Modelling the likely future workforce

Introduction

This research included a requirement to design an appropriate scenario-based modelling approach to anticipate future workforce needs and skill sets associated with the land uses required to support Scotland’s transition to net zero. The rationale for the modelling work was to identify the scale of future workforce needs required to deliver the policy targets set out in the CCPU 2020, particularly those relating to peatland restoration and woodland creation. Identifying these needs is critical in order to understand the potential for labour supply and demand to match (or not), thus leading to better labour utilisation and higher productivity. Information about the size and location of the future workforce is also critical to informing knowledge and evidence about the future of rural communities and decisions about infrastructure investments, in particular relating to demand for housing (of different types), transport and a range of vital services.

However, we were unable to find sufficiently reliable datasets on input costs to inform a robust approach. A detailed account of the research undertaken is set out in the Appendices, to initially assess existing research on the future of the labour market (both land-based and more generally) from the wider UK and Scotland (Appendix 12), to review approaches to scenario creation (Appendix 13) and to devise a sound approach to scenario-based modelling based on input cost information (Appendix 14). The approach is summarised here.

Scenario modelling work

Introduction

The research team set out to assess the effect on employment of the Scottish Government’s policy targets in relation to peatland restoration, woodland creation and regenerative agriculture, based on our review of:

  • the existing evidence about these activities, and
  • parallel studies which have adopted a variety of different methodologies to estimate future employment requirements (see Appendices 12 and 13).

An early decision was taken to step back from assessing future employment in regenerative agriculture as it was considered that the Scottish Government’s targets lacked sufficient specificity to be quantified in biophysical or monetary terms. In future, if a policy target is specified (e.g. a proportion of land area that should be under regenerative or low carbon agriculture, or a proportion of agricultural output which should be generated using these techniques, though such targets would be hard to agree, measure and monitor) then this modelling could be revisited using the approach proposed here.

The team began development of a model by focusing on the peatland restoration sector, where a search of the literature highlighted a particular knowledge gap.

Peatland restoration – overview of methodological approach

We examined the Scottish Government’s target to restore 20,000ha peatlands per year to consider the impact on employment in upstream sectors. Step by step details of our approach are set out in Appendix 14. We searched the literature for information on peatland restoration costs, seeking to understand unit costs of different inputs, including labour and machinery requirements, and how these may vary between sites.

Data challenges encountered

While the quality and availability of data on peatland restoration costs is increasing, information remains partial, and we have been unable to find a reliable indication of the cost structure of peatland restoration work within the published literature (see Appendix 14 for further information on peatland restoration costs that the team was able to find).

Several factors lead to substantial variations in peatland restoration costs. These include:

  • the condition of peatland to be restored, and then subsequently maintained.
  • the type of existing land use.
  • the restoration technique required.
  • remoteness and accessibility of the site.
  • the scale of work required (e.g. degree of drainage/number of dams required).
  • material requirements dependent on the degree of degradation.

While these factors are becoming better understood, it is not straightforward to discern their relative influence on the overall costs which are largely summarised per hectare (ha). We were unable to find information on how labour or machinery requirements may vary by site conditions, and to add further complexity, the costs are changing all the time as the cost of materials and equipment changes. Technology advances (e.g. LiDAR) may lead to reduced labour requirements over time too, although in contrast to this, costs may rise as the ‘easier to reach’ sites are restored first.

Overall, it was not possible to determine a reliable estimate for the cost structure for peatland restoration. However, the detailed evidence gathering conducted for this study provides a strong basis from which to tackle these data challenges, and build indicative estimates of future jobs required in peatland restoration.

Approximately half of all peatland restoration projects in Scotland are supported by Peatland Action. This provides a wealth of existing data and an opportunity to collect more detailed figures for analysis of current and future employment requirements.

Woodland creation – overview of methodological approach

Having first focused on peatland restoration, the research team then examined the Scottish Government’s 18,000ha per year afforestation target (from 2024/25), to consider the impact on employment of delivering this target. To inform this analysis we searched the literature for information on woodland creation costs, seeking to understand unit costs of inputs, such as labour and machinery requirements, and how these may vary between sites (for similar reasons to those outlined in Section 7.2.3 for peatland restoration sites).

We were similarly unable to find a reliable indication of cost structure for woodland creation within the published literature, and were unable to complete the planned analysis (see Appendix 14 for information that we did find on costs, including the useful work of Glaister in 2019).

There is potential to identify further detailed data sources which could inform a future analysis, if required. For example, the report published in March 2022 for Scottish Forestry, the Forestry Commission and the Welsh Government which explored the impact of investment in forestry on employment which may provide some useful insights, and we understand an update to work on the economic contribution of forestry to the Scottish economy is in preparation.

Net Zero and Land Based Employment

The impact of net zero on the land-based workforce

Although the team was unable to complete the modelling work, we reviewed prior studies that had considered the impact on employment of implementing net zero related land use change in the Scottish / UK context. We found:

  • a relative lack of research examining the impact of net zero commitments on employment in the land-based sector. This is however a rapidly expanding field and a number of relevant studies have been published while our work was ongoing.
  • the evidence base is entirely within the grey literature. The team is not aware of any peer reviewed academic literature that has sought to assess the magnitude of changes to employment relating to net zero commitments.[17]

Various studies have estimated changes to employment arising from specific activities within the land-based sector such as tree planting and peatland restoration. Some of these also assess the impact of particular policy targets. A report by WPI (2021) for Green Alliance provides an example of this and summarises marginal employment impacts (per 100 ha) identified by prior studies.

The recent Net Zero Workforce report by the Climate Change Committee (2023) seeks to evaluate the impact of net zero across the UK workforce. Within this they evaluate the impact on employment in Agriculture and Land Use, as one of six broad sectors of the economy. To our knowledge this is the only assessment of employment impacts across these sectors.

We also considered the evidence base for the likely impact on employment in specific sectors:

  • Forestry
  • there is a wide range in the magnitude of estimates across studies.
  • Glaister (2019) provides an estimate of the number of workers required to deliver six forestry work programmes. This could be regarded as providing a lower range estimate of direct employment in the forestry sector.
  • we are hesitant to suggest an upper range estimate from the current literature. An impact assessment drawing upon Westbrook and Ralphs (forthcoming) could provide an upper range estimate for the sector, and further assess indirect employment that would be supported by an expansion of activity.
  • Peatland restoration
  • there is a narrower evidence base for the likely impact of net-zero on employment, although the magnitude of estimates across studies is broadly consistent.
  • Agriculture
  • This is a notable omission. Agriculture is the largest land-based sector by output and employment, yet there is a relative lack of evidence concerning the likely effect of net-zero commitments on employment in agriculture. The Climate Change Committee (2023) report is the only estimate that the team has been able to find in their extensive search.

Similarly we are not aware of any studies which have sought to quantify the impact of net-zero on employment in the game and wildlife sector.

The impact of net zero commitments across the land- based sector

To our knowledge, the report by the Climate Change Committee (2023) A Net Zero Workforce is the only source which has assessed changes in employment across the land-based sector as a whole.

The Climate Change Committee (2023) assessed the potential impact of net zero on the UK workforce. Taking as a reference the technological and behavioural changes described by the Climate Change Committee’s Balanced Net Zero Pathway, they assessed the likely influence of such changes to key sectors of the UK economy.[18]

Following on from a review of the literature, the Committee defined specific scenarios to identify lower range and upper range estimates for changes to employment across the UK in the Agriculture and Land Use sector (detailed in Table 5 below). These scenarios do not necessarily reflect Scottish Government policy. Their estimates provide an indication of the likely direction and magnitude of changes to employment across the land-based sector, though as highlighted in the report and through the wide extent of estimates they present, there is considerable uncertainty regarding employment impacts.

The Committee estimated that the greatest potential for job creation is in afforestation, followed by non-livestock agriculture, while livestock agriculture is at greatest risk of job losses. Employment in food processing could either be positively or negatively impacted, while employment in peatland restoration shows modest potential for job creation, when compared to afforestation and non-livestock agriculture.

The impact of net zero commitments in forestry

Estimates of the net- zero workforce in forestry are summarised in Table 6 below. There is a relatively wide extent in the magnitude of estimates across studies.

The upper range estimate provided by the Climate Change Committee (2023) is considerably greater than has been suggested by prior studies and we see some reason to be cautious of relying on the upper end of this range (the method applied in creating the estimates is not detailed). In addition to this, work commissioned by the Forestry sector in Scotland has produced a more conservative range of estimates (see Table 6).

Work by Westbrook and Ralphs (forthcoming) has estimated the marginal employment effect of ten forestry case studies in Scotland. They outline considerations for how this might be used to assess the impact on employment of implementing the Scottish Government’s national target. The team believe that this approach offers a promising means to understand the net zero forestry workforce.

Glaister (2019) defined industry work programmes for key forestry activities, estimated work rates for each activity, then calculated the number of workers that would be required to fulfil those work programmes (see Appendix 5). A strength of this approach is that it gives an indication of the number of workers required in specific roles. For instance, estimating the number of workers required to plant trees is 941 FTE or 2041 seasonal workers working 45% of the year.[19]

A drawback of this approach is that it does not fully assess the wider indirect impact of an increase in forestry activity on employment through the wider forestry supply chain, for instance in building roads or supplying machinery. Glaister also adopted a narrower definition of the forestry sector than the prior CJC (2015) report and does not consider employment in forestry sector organisations, forestry land agents, forest recreation and tourism or local authorities. For these reasons, Glaister’s estimates might be regarded as a lower range estimate for the forestry sector. An impact assessment, drawing upon Westbrook and Ralphs could provide a robust upper range estimate for the sector.

The impact of net zero commitments in peatland restoration

Estimates of the net-zero workforce in peatland restoration are summarised in Table 7 below. While the evidence base is fairly small, the magnitude of estimates is broadly consistent across studies.

In the CCPU (2020) the Scottish Government estimated that 200 FTE direct contractor and delivery jobs would be created by their commitment to spend £25 million per annum on peatland restoration, though due to the seasonal nature of work this would likely require a greater number of workers each working part of the year. This is in line with the lower end of the range indicated by WPI (2021) and sits below that indicated by the Climate Change Committee (2023).

Further considering jobs supported indirectly through the wider supply chain, WPI (2021) estimate that as many as 800 jobs could be supported by 20,000 ha per year peatland restoration. This is broadly in line with the upper end of the range estimated by the Climate Change Committee (2023).

**WPI (2021) assess the target of 50,000 ha per year as implying between 500- 2,000 jobs. For ease of comparison this has been rescaled to reflect the Scottish target of 20,000ha per year.

***The 50,000ha per annum scenario reflects a prior recommendation by the Committee on Climate Change to restore 55% of peatland to good status by 2050, WPI (2021) estimate that this implies around 50,000 hectares restored per year (UK). Glenk and Martin-Ortega (2018) estimate that this 55% equates to approximately 1.6m ha of peatlands across the UK (Dicks et al., 2020).

****Hirst and Lazurus (2020) suggest that a future trend for peatland restoration could see the sector grow by five times the level of current activity. They estimate this could create 356 new jobs.

 

Additional issues to consider

Alongside the need to continue work on establishing estimates of the future scale and composition of the workforce, the literature and our stakeholder interviews highlight some further issues, which are inter-related, that require consideration when attempting to generate quantitative assessments. This demonstrates the importance of gathering both quantitative and qualitative data when undertaking scenario planning work.

Skills

In 2020 Skills Development Scotland produced a Climate Emergency Skills Action Plan which set out an overall direction of travel for the labour market in response to Scotland’s net zero commitments. This argues that reaching net zero by 2045 will require transformational change across the economy, including the emergence of new jobs and transitioning existing jobs to embed new green skills. Workers will require both hard and soft skills. The plan further emphasises the importance of meta-skills such as self-management, social intelligence, innovation and an ability to communicate well.[20]

Seasonality

The issue of seasonality is key to understanding the scale, type and location of future jobs in the land-based sector, in particular the extent to which it is possible for individuals to move between land-based sectors to perform different activities at different times of the year, or indeed between the land-based and other sectors. The potential for workers to connect different seasonal activities and work across sectors may be important for workers ability to meet accommodation and living costs in rural areas, and therefore to attracting sufficient workers to fulfil these roles.[21]

Based on the sources that we have reviewed (Appendix 12), we suggest that the main tree planting period is October – March, excluding December and January and that the key busy period for peatland restoration is August – March (with interruptions due to winter weather). Due to having similar busy periods it seems unlikely that roles within tree planting and peatland restoration will be fulfilled by the same individuals.

To attract workers to fulfil seasonal roles in tree-planting, it may be important to consider the potential for complementary off-season work. In this respect hospitality (commonly the second largest employer in rural areas) may have a complementary calendar, though perhaps a differing skill profile.

Attracting Workers

It will be necessary to attract workers across the land-based sector both to fulfil targeted increases in activity (particularly in tree planting and peatland restoration), and to offset natural attrition due to retirement and other factors.

Research highlights factors which may make this more challenging. Recent workforce studies have indicated that many employers across Scotland are experiencing recruitment challenges in a tight labour market.[22] Within the nature-based sector, Hirst and Lazarus (2020) point to a divide between graduate posts (drawn from national labour pool) and operational posts (drawn from local labour pool), with operational posts generally harder to fill and experiencing stiff competition from other sectors.

In future, increased competition for skills could serve to enhance wages. Westbrook and Ralph (forthcoming) suggest that wages in the forestry sector may have to rise to attract a sufficient supply of workers. They highlight that median pay for forestry workers (£20,590) is substantially less than the UK national average (£29,577) and less than in other skilled roles involving machinery operation, including agricultural machinery drivers (£28,062), road construction operatives (£28,460) and mechanical engineers (£37,050). Added to low wage rates, the nature of the work in terms of remoteness and isolation, its physical nature and level of potential danger, and the change in mindset needed for much of the activities (see the points made in stakeholder interviews for this project in Box 1), may also serve as further discouraging factors.

Anecdotally, it is said that wage rates in peatland restoration are often above the market rate. Despite this a shortage of local skilled peatland restoration contractors has been highlighted as a barrier to upscaling restoration efforts (Reed et al., forthcoming). This point was further reflected in stakeholder interviews (see Box 1).

Learning Pathways

A widely raised point is the need to attract learners to the land-based sector. Hirst and Lazarus (2020) report that low awareness of opportunities and the range of jobs available was cited as a challenge by stakeholders across the nature-based sector alongside the need to better engage young people and non-traditional groups.

This was further picked up in the CLBLR (2023) which recommended work to be taken to reframe the land-based sector as the ‘nature-based sector’ to be more inclusive of the range of activities within the sector.[23]

The CLBLR considered that a greater emphasis on sustainability and natural capital could enhance the perception of the sector, helping to attract learners. They further recommended supporting an increase in sector school/college partnership learning pathways (again see Box 1).

Considering the forestry sector more specifically, research by UHI, Lantra and the Institute of Chartered Foresters has pointed to a potential future skills shortage in the forestry sector if longstanding challenges around recruiting students and declining provision of higher education courses are not addressed.[24] They highlight a need to improve perceptions of the industry and make it more attractive to potential students.

Demographics, Housing and Employment

The Scottish Government’s National Strategy for Economic Transformation (March 2022) recognises a number of structural economic challenges including deep-seated regional inequalities with post-industrial areas lagging behind and rural and island areas facing particular challenges such as a falling labour supply, poorer access to infrastructure and housing challenges which are holding back local businesses. The Strategy goes on to note that:

“The transition to a net zero economy presents Scotland with the further challenge of achieving a just transition that delivers positive employment, revenue and community benefits, in contrast to the industrial transitions of the 1980s.”

Elsewhere green land use change has been highlighted as an opportunity with potential to address labour market challenges. For instance an analysis by WPI for the Green Alliance found that across the UK, areas with the greatest potential for afforestation also faced greater than average labour market challenges. They take this to imply that an increase in tree planting showed potential to create jobs in these areas (WPI, 2021).

For this to be feasible however there must be attention to wider rural challenges such as demographic ageing and rural housing provision. Given that rural residents may already be less mobile than their urban counterparts due to structural challenges such as a lack of local childcare and affordable transport and housing, this may mean that they are less able to take advantage of new opportunities that arise.

Coupled with this are challenges around delivering and accessing training in rural locations which may mean that rural workers are not able to access the most up-to-date education and training options available. Hirst and Lazarus (2020) highlight the importance of small and micro-businesses across the nature-based sector, which could be a barrier to enhancing skills provision as smaller businesses often lack the ability to access formal training delivery. Alongside this, the remote location of work alongside seasonality of employment can make training more costly and challenging to organise (Scottish Forest and Timber Technologies, 2020).

The information in Box 1 is based on an interview with an individual working in the land-based sector in an island community. Many of the points discussed here are illustrated in the quotes taken from the conversation.

Box 1. Peatland restoration and green jobs – an island perspective

Local perspective on national policy priorities in peatland restoration

“What we really need locally here are more contractors to carry out the work and specifically digger drivers and appropriate training for plant operators. Existing restoration contractors have tried everything to recruit them but we’re not getting anywhere. Without adequate numbers of machines and operators we can’t do the work. Part of the issue is that it requires skilled operators. There are plenty of skilled operators in the islands but we’re struggling to recruit them to work on peatland both because there is high demand for their skills and because the current funding model does not allow for land managers to restore their own peatland… Plenty of crofters have their own machinery and the skills to carry out the work but the current process requires the work to be tendered to contractors.”

‘Cathedral builder’ mindset

“Operators have to work on land that they’d never normally take a machine out on and be really careful to avoid causing further damage. There is such an expanse of peat to be restored that it requires a ‘cathedral builder’ mindset. Workers need to be able to keep going while recognising that they may never get to see the final result or what they might consider as tangible benefits.”

Tight labour market generally

“The local labour market is tight. Tight is not even the word – it’s never been like this before. Knitwear, crab, and seafood processors have lost access to a large pool of foreign workers and this has had a knock on effect across all sectors. …. There’s also the problem of housing, even where employers are able to attract workers from outside the isles, there’s nowhere for them to live. Property prices have increased exponentially here in the past 4 years, new regulations have pushed people out of the private rental market and the number of second homes, retirement homes, and holiday lets is putting huge pressure on housing stocks. Although there is investment in social housing it is not coming fast enough for young people starting out now.”

Encouraging young people into green jobs

“Local young people could be an asset. We have plenty of local young people and plenty of opportunities for them, but we are not matching the two at the moment. We need more engagement with schools so that people know that the full range of jobs that are there. In conservation programmes and citizen science programmes, for example, run by public and third sector organisations, recruits tend to be young graduates from outside the islands. This leads to a lack of local involvement and local knowledge in the development of conservation initiatives, which in turn compromises communication and ultimately the value of the results achieved.”

Green skills – a core skill for the future is the ability to be flexible

“Career guidance tends to focus on getting young people into university. There’s not enough recognition of the range of non-traditional work out there. Forget the idea that we don’t know what future jobs will look like, our current problem is that many of those supporting young people to make career choices don’t know what the employment market looks like right now.”

Conclusions

This project has reviewed evidence relating to the composition and condition of the land-based labour market and its likely future trajectory given the Scottish Government’s policy targets set out in the 2020 Climate Change Plan Update. We examined the potential for a methodological approach to model future labour requirements in the land-based sector in order to ensure that climate change and net zero targets are met.

The composition of the land-based workforce in Scotland

The research highlighted challenges in assessing the overall composition of the land-based workforce, with no commonly agreed definition, which in turn affects the way the required data is collected. The difficulty in identifying and clearly delineating some land based activities, such as peatland restoration, from the SIC system means that there is a lack of dedicated information on these activities within multi-sector labour market studies. The amount of information available varies between sectors, with much of it drawn from industry sponsored reports ..

. The research identified widely used estimates for key sectors, however due to differences in how employment is measured and how industry boundaries are defined, these are not directly comparable with one another. Industry groups in agriculture commonly depend on headcount figures which count part-time and full-time employment equally, while in forestry estimates are expressed as full-time equivalents (FTEs).

Differences in industry definitions also present a challenge. The agricultural sector within the June Census stops at the ‘farm gate’ (i.e. it refers to the total agricultural workforce on farms), whereas the forestry sector within the CJC (2015) study is broader and includes workers employed in timber haulage, forestry consulting, and local authorities. Employment statistics for the nature-based sector are also not directly comparable with those for agriculture or forestry because they already count part of agriculture and part of forestry and therefore combining figures for nature based employment with either forestry or agriculture would result in double-counting.

For all of these reasons it is not straightforward to determine how many people currently work in the land- based sector.

The current condition of the rural land-based labour market and key trends

Our analysis at local authority level using BRES data shows headline employment trends in agriculture and forestry over the last ten years, highlighting both similarities and differences between sectors.

A key area of similarity is that employment is strongly rural. Jobs in agriculture and forestry are predominantly located in rural areas. As such, the majority of employment growth since 2011 has occurred in Mainly Rural local authority areas.

Both agriculture and forestry have seen an expansion in the number of employees over the last decade, however they show differing trends in their total workforce. Within agriculture there has been a shift in workforce composition. A moderate increase in agricultural employees has been offset by a similar decrease in working owners, thus the total agricultural workforce is roughly the same in 2021 as it was in 2011. New positions have predominantly been for part-time and casual staff.

Meanwhile the total forestry workforce has increased substantially over the last decade, by around 50% between 2011 and 2021. The majority of new positions have been for full time staff. The number of working owners has also increased, though overall working owners are less significant than for agriculture, accounting for less than a quarter of the workforce, as compared to around half in agriculture.

Current and potential workforce opportunities exist in woodland creation, peatland restoration, a shift to regenerative agriculture and a growth in nature-based activities due to the Scottish Government’s climate change related targets. It is very difficult with current data to estimate how much and where opportunities are most likely to be concentrated, and the extent to which growth in employment in these sectors or in particular regions may result in decline in other sectors and regions.

Moreover, these opportunities are emerging at a time of ‘tightness’ in the current labour market where there are labour shortages being experienced in some regions and sectors. While this current ‘tightness’ may be primarily a result of labour market changes associated with the Covid-19 pandemic and Brexit, wider social trends, and in particular demographic ageing and an overall contraction in the population of working age, suggest that some tightness may continue. There are additional factors in rural areas which affect the size, shape and mobility of the workforce, including the availability of affordable housing, childcare and transport.

Modelling the future work force

The research identified a relatively limited evidence base examining the impact of net-zero commitments on employment in the land-based sector and the variations between sub-sectors. This project explored the potential for undertaking scenario modelling work but it was not possible to complete this using the approach proposed at the outset. There is potential to model future labour requirements and skills needs if detailed cost breakdown information for all of the policy target activities becomes available (i.e. woodland creation, peatland restoration, low-emission agriculture and nature-based activities).

A recent report by the Climate Change Committee (2023) gives an indication of the likely direction and magnitude of employment impacts within the land-based sector. While acknowledging considerable uncertainty around changes, the report indicates positive employment impacts in afforestation, non livestock agriculture and peatland restoration, alongside negative employment impacts in livestock agriculture, and a mixed picture for food processing.

The implied shift in sectoral composition raises important questions around the wider effects this may have on rural economies and communities. For example, how do the supply chains for those industries compare in terms of their size and geography and therefore the likely impacts of on rural economies? Will an expansion of tree-planting and peatland restoration activities and jobs support rural economies and communities in the same way as agricultural activities and jobs? Will these new workers live in rural areas year-round, spend their wages in the local economy and contribute to school rolls?

It is also important to consider the viability of seasonal roles in tree planting and peatland restoration. The ability of workers to connect different forms of seasonal employment may be important their ability to take on seasonal roles. However, due to having similar busy periods it is unlikely that jobs in tree planting and peatland restoration will be fulfilled by the same individuals. More generally, upscaling jobs in rural areas requires attention to wider rural challenges such as housing provision, demographic ageing and the affordability and availability of services including transport.

There is clear value in exploring qualitative and quantitative data for scenario-based work, particularly in an area as complex as the land-based labour market where there will be trade-offs and regional differences. Qualitative ad hoc or tailored exercises can provide complementary insights to those provided by quantitative modelling approaches. A greater understanding of these issues is critical to promoting a just transition and enabling the sustainability of rural communities as Scotland transitions towards its net zero targets.

Appendix 1: Project aim, objectives and outline methodological approach

The aim of this project was:

“To achieve a system-wide overview of the existing statistics and what they tell us about the current land-based labour market in the rural land use sector in Scotland.”

There were three key objectives and the research team identified four tasks to undertake to achieve them: 

Objective 1: To assess the existing data for the land-based labour market in the rural land use sector in Scotland in order to understand the composition of the workforce and associated skills and identify key gaps. 

Task 1: The desk-based identification and review of key sources of quantitative, statistical data on Scotland’s rural labour market, with a focus on understanding the composition of the rural workforce and associated skill requirements, and its resilience to change. The research team undertook an extensive search for publicly available and secure access only information relating to the labour market in the UK and Scotland. We also identified any gaps in our understanding, particularly relating to sectors/activities that may become more important in future. 

Objective 2: To analyse the available evidence and report on the current condition of the rural land-based labour market, including trends of continuity and change since 2010. 

Task 2: The desk-based identification and review of available academic and other relevant, non-quantitative evidence on the current condition of the rural land-based labour market and related skills issues, including trends of continuity and change since 2010.

Objective 3: Using a scenarios approach, to model likely future rural workforce needs and skill sets associated with the land uses anticipated as part of the transition to net zero. The scenarios were aligned with the policy targets set out in the Climate Change Plan Update, and focus on the key delivery dates of 2030 and 2045. 

Task 3: Informed by a review of similar studies that have sought to model future workforce needs and skill sets associated with the land uses anticipated as part of the transition to net zero, and a review of how scenarios have been developed and used in similar studies, we designed a methodological approach to create a working model to explore likely future rural workforce needs and skillsets associated with the land uses anticipated as part of the transition to net zero.

Task 4: When the team was at the stage of having a draft report and a preferred methodology for the scenario modelling work, we undertook a small number of interviews with relevant stakeholder organisations and SRUC colleagues to sense-check our evidence review, scenarios and modelling work. Ethical approval for these interviews was obtained from SRUC’s Social Science Ethics Committee. Interviewees were sent the draft report to read in advance of the conversation (where time permitted) and interviews were recorded (with permission). The interviews were relatively unstructured, allowing the interviewee scope to raise issues of importance to them to inform the project. The data from these interviews is reported here anonymously with no individuals or organisations identified.

Appendix 2: Policy context for the land-based labour market

A2.1 Climate, environment, place-based and skills policies

The Scottish Government’s Environment Strategy sets the overarching framework for Scotland’s strategies and plans relating to the environment and climate change. The vision set out in this Strategy is: 

“By 2045 – By restoring nature and ending Scotland’s contribution to climate change, our country is transformed for the better – helping to secure the wellbeing of our people and planet for generations to come.” 

The Scottish Government’s climate change legislation sets a target date for net zero greenhouse gas emissions by 2045. Changes to climate change legislation and associated consumer behaviours to move towards greater sustainability will impact on the economy and society, including the labour market, in various ways.

The Government’s Climate Change 2018-32 Plan, published in 2018, and its Climate Change Plan Update published in late 2020, describe the large-scale changes needed to help reach our statutory net zero targets. The third progress report on the Climate Change Plan Update was published in May 2023. In addition to this, the Scottish Government also has ambitious targets to end biodiversity loss by 2045, requiring simultaneous and significant improvements in nature restoration. A new Scottish Biodiversity Strategy to 2045 was published in December 2022.

Changes to Scotland’s workforce will be required to meet these ambitious targets, with land-based activities having a key role to play, in particular in rural areas where much of this activity can be found; this includes agriculture, forestry, peatland restoration and nature-based activities. Recent policy documents set out the direction of travel in these sectors, including the Scottish Government’s Agriculture Vision ‘Sustainable and Regenerative Farming – next steps’ (published in March 2022), the Scottish Government’s Forestry Strategy 2019-2029 and its planned Circular Economy legislation and Route Map to 2025 and beyond. There have also been independent inquiries and reports, such as the Farming for 1.5o inquiry and the Commission for the Land-Based Learning Review which have contributed to thinking regarding the future shape of land-based activities. The independent review of Scotland’s skills delivery landscape, chaired by James Withers reported in June 2023, having undertaken a call for evidence in Autumn/Winter 2022.

At the same time, some elements of the policy context are yet to be confirmed, including the future support regime for agriculture (though more information has been available on this since the speech by the Cabinet Secretary for Rural Affairs, Land Reform and Islands Mairi Gougeon at the Royal Highland Show in June 2023) and the shape and organisation of Scotland’s agricultural knowledge and innovation system (AKIS) (a report by the James Hutton Institute published in May 2023 undertook an options appraisal for this), both of which are highly relevant to this project.

The work of the first Just Transition Commission between 2019 and 2021 and the second Commission which started in 2022, recognises the potential for people and places to be affected in different ways by these workforce changes. The Scottish Government recognises the scale of the transition required in its response to the first Commission’s final report and has committed to setting out a series of just transition plans. A discussion paper to support engagement on a just transition in the land use and agriculture sectors was published in June 2023.

The Land and Agriculture Just Transition Plan (LAJTP) is due to be published in line with the future arrangements for agricultural support to replace the CAP following the UK’s EU exit, and will focus on those who live and rely on Scotland’s land for their livelihoods and wellbeing and on maintaining thriving rural and island communities. The LAJTP will look to demonstrate how Scottish Government policies to tackle and adapt to climate change and wider Scottish Government action will support:

  • the creation of new or expanded economic opportunities in sectors such as nature-based solutions, natural capital investment and maintenance, green tourism, sustainable and regenerative food production and wood products.
  • an increase in health and wellbeing for both people and the environment, and
  • greater community empowerment as we look to ensure those already disadvantaged do not carry the burden, and that more benefits such as skills enhancement and employment opportunities flow to local communities.

In terms of its policies for specific places, Scotland does not have a distinct rural policy or strategy; the Scottish Government takes the approach of mainstreaming where rural issues are reflected in mainstream policy development. In late 2022, there was a new commitment for the projects which are funded as part of the National Strategy for Economic Transformation (NSET), to undertake checking using new ‘Rural Lens’ guidance to ensure that these projects take account of and meet the needs of Scotland’s rural communities and people. In April 2023, in his vision for Scotland, First Minister Humza Yousaf announced that a Rural Delivery Plan would be published by 2026 and alongside this in the same timescale, a Remote, Rural and Islands Housing Action Plan. Since the Islands (Scotland) Act 2018, which exists to support and help meet the unique needs of Scotland’s islands, the Scottish Government has committed to publish a National Islands Plan every five years with an annual review, and, alongside other relevant authorities as set out in the 2018 Act, a commitment to undertake Islands Community Impact Assessments.

The Scottish Government’s Climate Emergency Skills Action Plan sets out the Government’s plan to maximise the transition to net zero by 2045, ensuring that the workforce has the skills required to make the transition to net zero just, fair and inclusive to all. Demand for green jobs and associated green skills is expected to increase rapidly in response to these policy drivers and to wider consumer behaviour changes. Linked to this, fair work is an important policy driver for Scottish Government, particularly given that the Covid-19 pandemic has exacerbated existing socio-economic inequalities. The Government’s Covid-19 Recovery Strategy focuses on a number of priority actions including upskilling and retraining opportunities for employees impacted by the pandemic and the transition to net zero, support for low-income families most at risk of poverty, and mental health and wellbeing support for children and young people.

A2.2 The National Strategy for Economic Transformation (NSET)

It is worth adding further information about the NSET, which was launched in March 2022 and demonstrates, amongst other things, how central natural capital and natural capital based sectors are to economic policy in Scotland.

The Strategy recognises a number of structural economic challenges which preceded the Covid-19 pandemic, including Scotland’s ageing population and relatively high level of economic inactivity (one in five people in Scotland). Structural inequalities led to many households living in poverty and Scotland’s productivity lags behind that of many advanced economies. There are also deep-seated regional inequalities with post-industrial areas lagging behind and rural and island areas facing particular challenges such as a falling labour supply, poorer access to infrastructure and housing challenges which are holding back local businesses. The Strategy goes on to note that:

“The transition to a net zero economy presents Scotland with the further challenge of achieving a just transition that delivers positive employment, revenue and community benefits, in contrast to the industrial transitions of the 1980s.”

Nevertheless there are also notable strengths:

  • Scotland is in the top quartile of OECD countries for higher education, research and development,
  • the percentage of the population with tertiary education, and
  • young people’s participation in the labour market.

Looking to the future, the NSET notes the Scottish Government’s aim in relation to achieving a more skilled workforce in Scotland, where there is a focus on the transition to net zero, the digital revolution and lifelong learning. Through three NSET projects funded on the skills theme, the focus is on adapting the education and skills system to make it more agile and responsive to economic needs and ambition. This includes supporting and incentivising people and employers to invest in skills and training throughout their working lives and expanding Scotland’s available talent pool at all skill levels to give employers the skills pipeline they need to take advantage of opportunities.

Specific NSET actions around skills include implementing the next phase of the Green Workforce Academy and implementing a lifetime upskilling and retraining offer that is more straightforward for people and employers. Importance is also placed on the implementation of the Climate Emergency Skills Action Plan, the Green Jobs Skills Hub to share information on skills shortages and opportunities throughout the labour market, and the Commission for the Land Based Learning Review (CLBLR) which reported in January 2023 and offers an opportunity to link across existing work in the Skills Action Plan for Rural Scotland and the Climate Emergency Skills Action Plan. Closely linked to these developments, the new SkillSeeder web platform was set up in 2020 as a skill sharing marketplace funded through CivTech Challenge 5 where courses and training can be listed across all sectors and those seeking training can find information and sign up in one place.

The NSET also refers to the fair work agenda which is a key policy driver for the Scottish Government and also its Future Skills Action Plan which built on the recommendations of the Enterprise and Skills Board’s Strategic Plan published in 2018. The Action Plan contains four themes:

  • Increasing system agility and employer responsiveness;
  • Enhancing access to upskilling and retraining opportunities;
  • Ensuring sustainability across the skill system; and
  • Accelerating the implementation of the learner journey review.

A2.3 The Climate Change Plan Update policy targets – further information

The work undertaken in this project is particularly aligned with the policy targets set out in the Climate Change Plan Update (CCPU).

The CCPU notes the Scottish Government’s commitment to green recovery from the Covid-19 pandemic which captures the opportunities of our transition to net zero:

“That means creating green jobs, developing sustainable skills and nurturing wellbeing. This approach recognises climate change as a human rights issue and the transition to net zero as an opportunity to tackle inequalities.”

Scotland has ambitious targets to end it’s contribution to climate change by 2045: a commitment to reducing emissions by 75% by 2030 (compared to 1990) and to net zero by 2045.

The Update emphasises that:

“Scotland’s natural capital is one of our greatest assets and is central to our future net zero economy, developing thriving rural economies based around woodland creation, peatland restoration and biodiversity, as well as sustainable tourism, food and drink and energy” (p9).

The Update also calls for a coordinated approach, a whole system view (as taken for example in the Third Land Use Strategy), across sectors and policy targets, though the document itself contains policies and targets for individual sectors.

At the centre of the Scottish Government’s commitment to securing a just and green recovery, is a commitment to increase the number of good, green jobs, and to enable people to access these jobs through training and reskilling. To further align the skills system with the demand resulting from a green recovery and the transition to net zero, the Climate Emergency Skills Action Plan was also published alongside the Update.

The policies and targets in the Update can be summarised as follows:

  • Land use, land use change and forestry:
  • The Update contains plans to significantly increase forestry and peatland restoration in particular to reduce greenhouse gases and other pollutants, and increase the levels of carbon dioxide being absorbed and locked up in timber products.
  • The Update sets out a plan to continue to expand forest cover in Scotland, with an increase in new woodland creation from the current target level of 12,000 ha annually in 2020/21 to 18,000 ha in 2024/25. Scottish Forestry and Forestry and Land Scotland will work with investors, carbon buyers, landowners and market intermediaries to increase private investment in new woodlands in order to increase the woodland carbon market by at least 50% by 2025. 
  • As of March 2020, over 25,000 ha of peatland have been put on the road to restoration, and earlier this year we announced a £250 million ten-year funding package to support the restoration of 250,000 ha of degraded peat by 2030. To deliver on the 2032 emissions reduction envelope annual peatland restoration needs to be far higher than the current 20,000 ha annual target and we will work closely with delivery partners, land owners, managers, farmers and crofters to continue to encourage more restoration of peatland, both traditional bog but also land that offers the highest emission savings per ha. 
  • Agriculture:
  • There is recognition in the Update of the need for agriculture to produce high quality food and deliver high environmental standards and emissions reductions going forward, as well as manage soils and grasslands appropriately and deploy technology innovatively to support all of these activities.
  • The Update provides a routemap for agricultural transformation, building on the work of the farmer led groups, and including a shift towards low carbon sustainable farming. The Agricultural Transformation Programme will be scaled up to enable farmer and crofters to purchase equipment to reduce emissions and support practice change. Options to explore multi-faceted land use will also be followed, including forestry, peatland restoration and management and biomass production, especially for those farmers wanting to step back from agricultural businesses.
  • Electricity:
  • The CCPU announces further policies to continue the rapid growth in renewable energy generation over the past twenty years, moving from a low to a zero carbon electricity system, with the potential for NETs to deliver negative emissions
  • Renewable energy generation in Scotland accounts for the equivalent of 50% of our energy demand across electricity, heat and transport by 2030
  • Publish a bioenergy action plan in 2023
  • Waste and circular economy plans/targets:
  • Continue to embed circular economy principles in wider green recovery
  • Increasing recycling, reducing food waste, reducing materials going to landfill

The Update contains a section which outlines what the policies mean in practice in terms of a pathway to 2032 (p18). This section of the report states:

“By 2032, the natural environment and landscapes around us will have undergone significant restoration, with a sustainable land use system that prioritises nature and biodiversity. 21% of our land will be covered by forest, following increased funding of £150 million as well as our target of planting 18,000 hectares per year by 2024/5. We will also have restored over 250,000 hectares of peatland with £250 million of investment over 10 years, protecting this significant carbon store, and restoring wetland habitats. The prioritisation of these “nature-based solutions” and restoration projects will deliver multiple benefits, not only in terms of carbon sequestration, but also enhanced biodiversity, improved air and water quality, and landscapes and ecosystems that are more resilient to climate change.

Meanwhile, the agricultural sector will have supported these changes in land use, through the use of appropriate land for afforestation, including further integration of woodlands on farms, and peatland, while continuing the important role of food production. Farmers and crofters will continue to be supported for their key roles of producing high quality food and environmental stewardship while meeting conditionality for delivery of high environmental standards for emissions reduction and biodiversity. They will be adopting all available low-emission technologies and practices supported by the introduction of new approaches, alongside environmental conditionality. Through partnership working between government and industry, for example through the work of the farmer-led groups and realigned and enhanced advice, agricultural businesses will have the skills and tools they need to produce food more sustainably, while adopting new technologies and innovative approaches.”

Appendix 4: Defining the land-based sector

Lantra Scotland is the sector skills organisation for land-based activities in Scotland. The organisation’s website has a wide range of information on pathways into jobs and qualifications. In their 2009 Environmental and Land Based Scottish Sector Profile report they define the sector as including a set of SIC (2003) codes[25] (see Box A1).

A picture containing timeline

Description automatically generated In its 2012 skills assessment report for the Agriculture, Forestry and Fishing sector, Lantra notes that the sector has a key role in feeding our nation and is indispensable for our current and future economic prosperity. Businesses in the sector safeguard the UK’s natural environment and natural heritage and are on the front line in the drive for food security, sustainable development, growing the rural economy and adapting to climate change by reducing greenhouse gases and creating more renewable energy. More specifically in terms of the SIC codes (2007) included, Lantra include Code 01 (crop and animal production), 02 (forestry and logging), 03 fishing and aquaculture and 75 (veterinary activities). However, they note that the sector is broader than these categories, and includes farming, horticulture, viticulture and hunting and trapping, as well as aspects of animal health and welfare. Forestry and logging consists of silviculture (forest management), logging and coppicing. Fishing includes both fresh water and marine fishing, while aquaculture covers the farming of freshwater and marine plants and animals. Support services to these industries (such as agricultural consultants) and plant propagation are also included in the definition. Veterinary activities covers farm animals and domestic pets, and in terms of occupations, the sector includes veterinary surgeons and veterinary nurses as well as any other auxiliary personnel. Outside the scope of this skills assessment are research and development activities relating to the sector, such as plant trials and biotechnology.

The (UK-wide) National Land Based College (‘the one stop shop for land based careers and skills’), refers to the UK Government’s approach of regarding ‘land based’ careers as the:

“Agriculture, Environmental and Animal Care sector which offers a range of career opportunities[26]. The term ‘land based’ traditionally relates to farming and industries connected to the land and environment, including horticulture, food production, forestry, conservation, landscaping and equine (horses)…Land based careers are diverse and use a number of different skills. Many roles combine cutting edge science, engineering and IT with an understanding of the natural world and how it works. Skills within the more creative leisure sectors are also required, with opportunities in landscape design, floristry, tourism and recreation. Careers can also include working with animals, nature conservation and caring for our land and environment. Many of the careers span a number of the areas above, and skills gained are transferrable between these sectors.”

The NLBC has worked with City and Guilds to design technical qualifications to increase skill levels in the land-based sector, including agriculture, animal management, environment, countryside and conservation, equine, forestry and arboriculture, horticulture and land-based engineering.

The research team also reviewed the remit of the Commission for the Land Based Learning Review (CLBLR) which was appointed by the Scottish Government to undertake a ‘root and branch’ review of learning in Scotland’s land-based and aquaculture sectors, from early years to adulthood. The CLBLR provided independent, evidence-based advice to Scottish Ministers around the best ways to provide opportunities and qualifications through school, college, university, and work-based learning, including apprenticeships, for more people and specifically more women, to work with and on the land, particularly in green skills. The work of the CLBLR supports the Government’s ambitions of delivering a just transition to net zero, by ensuring Scotland’s learning system equips people with the skills and knowledge needed to work in the country’s land-based sectors as well as any new and emerging green occupations in land-based sectors. The Scottish Government will respond to the CLBLR’s report later in 2023.

The review considered the learning pipeline for the following sectors: 

  • agriculture 
  • aquaculture 
  • biodiversity 
  • environmental conservation 
  • equine 
  • fisheries management 
  • food and drink processing 
  • forestry, trees and timber 
  • game and wildlife 
  • horticulture 
  • peatland restoration

The review did not include nature-based tourism, outdoor recreation and renewables (wind, hydro and solar)[27].

The Scottish Qualifications Authority (SQA) makes reference to the ‘land-based and environment sector’ which it argues makes up 6% of all UK businesses, employing 660,000 people. The SQA describes that its qualifications have been developed with Lantra and industry contacts (and they link to a variety of industry bodies[28]) to ensure they are relevant and provide people with the skills needed to work within this sector, and cover a wide variety of disciplines, including: animal care, aquaculture, environmental management, horticulture, forestry, landscape management, wildlife and conservation management, and much more.

Pearson, an awarding body offering academic and vocational qualifications, offers ‘land-based studies’ which includes agriculture, horticulture and land-based studies, with the latter including a range of subjects/courses, including plant and soil science, environmental and conservation management, wildlife ecology, developing a land-based enterprise, farm livestock husbandry, crop production, planting/care of plants, etc. which could support people going into a variety of jobs. The National Careers Service in its Environment and Land category includes a very wide range of occupations[29]. The Careermap website, in its sector spotlight on the land-based and environmental industries, splits the sector into three broad areas: land management, animal health and welfare, and environmental industries.

Impact of changes in the CAP regime on rural (non-agricultural) businesses — SRUC, Scotland’s Rural College

As evident in Table A2, the team reviewed a range of sources of employment information and this final section of the Appendix provides a little more information from some of the key sources.

The Scottish Government produces secondary analysis of the latest labour market information from a range of sources, including the ONS’ Labour Force Survey, the Annual Survey of Hours and Earnings and the Annual Population Survey in its Labour Market Summary. It also publishes an annual report on Scotland’s Labour Market based on Annual Population Survey data with the most recent version published in 2020/21. This report contains information on a range of labour market issues, including employment rates (including by local authorities, sector and age), types of work (e.g. underemployment, contractually secure employment, gender segregation and job-related training) and skills. It also provides local authority level data on the proportions of people with low/no qualifications.

Skills Development Scotland (SDS) hosts a large amount of data on its website relating to Scottish employment, labour market and skills issues, including its regular Covid-19 Labour Market Insights reports. The Scottish Labour Market Information and Intelligence (LMI) Framework (involving SDS, Highlands and Islands Enterprise, Jobcentre Plus, Scottish Enterprise, Scottish Funding Council, Scottish Government, Scottish Qualifications Authority and the Improvement Service) encourages all organisations to work collaboratively to collate, analyse, publish, etc. labour market evidence. Through this framework, SDS provides Regional Skills Assessments (RSA) and Sectoral Skills Assessments (SSA, including information on job postings, employment forecasts and skill requirements, amongst other things). Both of these are built from existing datasets combined with regional/industry insights, and provide coherent, high-level evidence to inform future investment in skills. More information on these assessments is provided in the sector-specific sections later in the report. SDS also has a RSA Data Matrix Interactive Tool which provides data on over 80 indicators at Local Authority level, and for other sub-regional geographies.

SDS’s Covid-19 Labour Market Insights Report from July 2022 notes the strong inflationary pressures, worker shortages, supply chain challenges, the cost of living crisis and the projection that the UK will enter a recession towards the end of this financial year as important issues impacting on the current Scottish (and UK) labour market. It goes on to note that the supply of people in the labour market has been impacted by high levels of economic activity, EU exit and demographic challenges. Labour shortages remain a dominant issue for businesses in Scotland, due to people being reluctant to change roles and challenges funding suitably skilled candidates and demand for workers remaining exceptionally high. The CIPD’s Labour Market Outlook from Summer 2022 also reports that employers are reporting labour shortages as a dominant issue across all sectors. They are increasingly focused on upskilling existing workers (41%), followed by advertising more jobs as flexible (35%) to tackle recruitment challenges. In this Outlook, 47% of employers reported having hard-to-fill vacancies.

A Fraser of Allander Institute survey (the Scottish Business Monitor) from May 2022 also reports high numbers of businesses experiencing recruitment difficulties and problems filling roles. They note a variety of reasons, including candidates lacking skills/ experience, a lack of applications overall, and sometimes candidates’ wage expectations being higher than businesses could offer. Some businesses also reported difficulties retaining staff, including due to increases in remote jobs in the labour market (such as people being offered highly paid jobs in the London labour market but able to work in rural and island Scotland, for example).

Appendix 6: Green skills and green jobs

Terms such as ‘green transition’, ‘green skills’ and ‘green jobs’ have become more widely used in relation to the changes required in labour markets to meet climate and environmental goals (such as implementing circular economy practices, enhancing biodiversity, etc.), and to ensure a sustainable recovery from the Covid-19 pandemic. For example, as noted in SDS’s February 2022 Sectoral Skills Assessment for the Agriculture, Forestry and Fishing sectors:

“green jobs are at the forefront of the Government’s plans for recovery. Demand for green jobs (and green skills) is expected to increase rapidly as a result of policy and legislative drivers and consumer choice.”

However, they remain poorly defined and there is no single agreed way to quantify them. The UK Government has not set out a definition of ‘green jobs’, nor how it will measure progress towards its ambitions –though a UK Green Taxonomy is under development and could provide this in future. The ONS estimates the number of UK green jobs in two ways:

  • UK employment in the Environmental Goods and Services Sector (EGSS), defined as ‘areas of the economy engaged in producing goods and services for environmental protection purposes, as well as those engaged in conserving and maintaining natural resources’; and
  • Information collected from businesses through the Low Carbon and Renewable Energy Economy (LCREE) survey, focussing on (a different) 17 sectors[30] deemed low-carbon or related to renewable energy and defined as ‘economic activities that deliver goods and services that are likely to help the UK generate lower emissions of greenhouse gases, predominantly carbon dioxide’.

The International Labour Organisation (ILO) confirms the lack of an agreed definition of ‘green jobs’ (ILO 2018 p. 53, p135). They argue that a ‘purist’ definition takes a narrow approach defining them strictly in terms of green credentials – jobs that ‘contribute substantially to preserving or restoring environmental quality’. However, the ILO tends to take a broader definition, arguing that green jobs are ‘decent jobs that contribute to preserve or restore the environment, be they in traditional sectors such as manufacturing and construction, or in new, emerging green sectors such as renewable energy and energy efficiency’.

Contributors to the UK Government’s House of Commons’ Inquiry into ‘Green jobs and the just transition’ (p7-8) identified a range of other possible definitions, some of which included social care and the emergency services; others included all jobs because people across all jobs have an obligation to take action to protect the environment.

The ONS identify two further ways green jobs could be measured:

  • the sectoral approach, which involves identifying relevant sectors, e.g. renewable energy, and either assuming all jobs in this sector are ‘green’ or deciding which jobs within the sector are ‘green’ and which are not; and
  • O*NET, a United States database, which sorts jobs in sectors that could make up a ‘green economy’ into three categories, based on the interaction between skills and the transition to a greener economy.

Following the UK Government’s Green Jobs Taskforce definition of green jobs (p9), would encompass a wide variety of different sectors, including jobs in nature and habitat management, the circular economy, etc.:

employment in an activity that directly contributes to—or indirectly supports—the achievement of the UK’s net zero emissions target and other environmental goals, such as nature restoration and mitigation against climate risks.

The UK Government’s Green Jobs Taskforce report published in 2021, referred to the Government’s Ten Point Plan for a Green Industrial Revolution published in 2020, and builds on an inclusive definition of green jobs and skills noting that every job has the potential to turn green and that there is a huge range of skills which will support the net zero transition.

Focusing on Scotland, increasing the number of green jobs has been a priority for the Scottish Government for several years, in order to reach ambitious environmental and net zero targets (see for example, the Programme for Government 2020-21, which announced £100m over the next five years for the Green Jobs Fund to support new and increased opportunities for green job creation across Scotland).

So, there is clear evidence both internationally and at UK level that green skills are regarded as increasingly important, but a lack of clarity over whether all jobs are potentially green, or only sectors related to environmental activity – or even certain jobs within certain sectors – should be included. However, without a clear definition it is impossible to quantify where these new jobs are, what type they are, what pay levels they offer and what skill levels they require, in order to inform the future skills and training plans of education and training institute and businesses themselves.

The Green Jobs in Scotland report, commissioned by the Implementation Steering Group behind Scotland’s Climate Emergency Skills Action Plan and supported by the Scottish Government and Skills Development Scotland was published in November 2022. The report argues that, in order to ensure that everyone benefits from the net zero transition, it is crucial to have a clear understanding of what constitutes a green job and to determine the future jobs and skills needs. It goes on to argue that the definition should be inclusive to take account of the impact that the net zero transition will have on a broader range of jobs.

This recently published Green Jobs in Scotland report defined three different categories of green jobs:

  • New and Emerging: The impact of green economy activities and technologies creates the need for unique work and worker requirements, which results in the generation of new occupations. These new occupations can be entirely novel or ‘born’ from an existing occupation. An example is solar system technicians who must be able not only to install new technology but also to determine how this technology can best be used on a specific site.
  • Enhanced Skills and Knowledge: The impact of green economy activities and technologies can result in significant change to the work and worker requirements of existing occupations. This impact may result in an increase in demand for these occupations. The essential purposes of the occupation remain the same but tasks, skills, knowledge and external elements, such as credentials, have been altered. An example is architects, an occupation in which greening has increased knowledge requirements pertaining to energy efficient materials and construction, as well as skills associated with integrating green technology into the aesthetic design of buildings.
  • Increased Demand: The impact of green economy activities and technologies can increase employment demand for some existing occupations. However, this impact does not entail significant changes in the work and worker requirements of the occupation. The work context may change but the tasks do not. An example is the increased demand for electrical power line installers and repairers related to energy efficiency and infrastructure upgrades.

The Green Jobs in Scotland research has developed a new green occupational definition, or a ‘GreenSoc’. The GreenSoc is based on an adaption of the three types of green occupations, and then applied to Labour Force Survey (LFS) data and data scraped from job vacancy websites. The report includes an analysis of green jobs by industry, occupation and demographics, and in terms of the latter, identifies eastern Scotland and south west Scotland as where demand for new and emerging green jobs is highest.

The report highlights a number of limitations in developing GreenSoc for Scotland which are relevant for the work being carried out in this project. These limitations include a lack of sensitivity in both the Standard Industrial Classification (SIC) and the Standard Occupational Classification (SOC), where the classification at four digital level (which is standard for the SOC; the SIC codes were updated to five digits in 2007 to provide more nuance) is blunt in terms of providing detailed information on the exact tasks, skills and knowledge of any occupation. The problem of being unable to disaggregate larger occupational or sectoral codes is a challenge that is important in this research. The report argues that what is ideally required to better inform and drive awareness and action to support reskilling and upskilling is data disaggregated at the 5-digit or even 6-digit level within the SOC.

The Green Jobs Workforce Academy notes that the Scottish Government has prioritised six sectors in Scotland’s journey to net zero (they are important to the economy and to net zero too): construction and the built environment; transport; nature; energy; engineering; and life and chemical sciences. In terms of the nature sector, the ‘My World of Work’ website notes plans for a five-fold increase in peatland restoration, a doubling of tree planting and more investment in the Woodland Carbon Code. It notes the need for 9,900 new workers in the agriculture, forestry and fishing sectors over the next three years (in contrast to the decline in jobs in agricultural production and the food sector predicted by the Climate Emergency Skills Action Plan 2020-2025, CESAP) and that it is expected by 2031 there will be around 18,200 new job opportunities in: crop and animal production; fishing and aquaculture; agriculture; finance; urban green infrastructure; tourism; forestry, trees and timber; peatland restoration; sustainable tourism; green finance; urban greenscaping; and integrated land management.

The research team identified a number of other reports exploring ‘green jobs’. For example, the Greening the Giants Report produced by Onward in 2021 notes that there are 12 sectors where it will be challenging to decarbonise, including agriculture. It notes that this sector is geographically concentrated which will result in spatially uneven consequences (see also WWF’s 2022 Land of Plenty report and the Carbon Brief 2022 report), though there is no detailed discussion of future jobs/skills requirements (see also the NFU’s [2019] report on Achieving Net Zero). The Onward Report recommends implementing a gradually rising regulatory baseline for soil and animal husbandry within the Environmental Land Management (ELM) scheme, and including agriculture in the emissions trading system and introducing innovation grants for vertical farming and cultured meat projects. The Economy 2030 report from the Resolution Foundation with the Centre for Economic Performance at LSE focuses on the theme of ‘green vs brown jobs’ and the regional differences in terms of the geographical distribution of each, but there is little discussion of the land-based sector specifically.

A report to the European Commission by Bowen and Hanke in 2019 estimated green jobs by industry and found that some low emitting industries (such as real estate activities) had a greater proportion of people in potentially green jobs than some high emitting industries (such as agriculture, forestry and fishing). The report argues that the journey to net zero may involve pervasive changes to the composition of jobs, much of which will be achieved by labour market turnover, where employees switch the industry in which they work.

Table A4 (Table 27 reproduced from Rural Scotland Key Facts 2021) shows the breakdown of the labour market in rural areas by SOC. This shows that across Scotland, the highest proportion of workers is in the lower managerial and professional occupations classification (with the rural proportions lower than in the rest of Scotland, though still accounting for one in four workers). While remote rural areas have a lower proportion of people in the higher managerial and professional occupations classification (12%), the proportion of workers in this category is highest in accessible rural areas (the data tables that accompany this report can be found online here).

Figure A1 below shows the sectoral breakdown of employment in rural Scotland. This is also taken from Rural Scotland Key Facts 2021 (Figure 12 in Rural Scotland Key Facts 2021). This shows that the agriculture, forestry and fishing sector accounted for 15% of employment in remote rural Scotland in 2020, compared to 12% in accessible rural Scotland (and only 0.5% in the rest of Scotland). This sector accounts for the highest proportion of private sector employment in remote rural areas; only the public sector accounts for a higher proportion (17% in both accessible and remote rural Scotland).

It is also worth providing some detail here on the Skills Action Plan for Rural Scotland 2019-21 which contains further discussion on some of the challenges of rural labour markets. The Plan notes the need to understand various key features of rural areas which underpin any action, including:

  • where they are,
  • their diversity,
  • the diversification of the rural economy away from the primary sector in recent years,
  • the need for a robust evidence base,
  • the need to understand how rural-specific and national policies and practices play out in rural locations, and
  • the need to understand how jobs and skills interventions play out in relation to wider economic and social issues as mentioned above, including the availability of affordable housing, transport infrastructure, etc.

The Plan sets out the relatively complex policy context for skills and jobs interventions, which includes Skills Investment Plans for specific areas (including the Highlands and Islands and the South of Scotland, for example) and sectors (including several of relevance to rural Scotland such as food and drink, tourism, aquaculture and the timber and forest industries), plus City Region and Growth Deals such as the Borderlands, sector strategies (including for agriculture, tourism and food and drink) and organisational strategies, including for HIE and SOSE.

The Plan identifies some of the particular challenges of delivering training and skills provision in rural areas where learners and employers are dispersed, demographic ageing is occurring at a faster rate than is the case in the rest of Scotland and employment rates are generally high, with lots of people working part-time, from home and often in multiple jobs, but with low productivity levels. It notes that over the period 2018-28, total requirement (the number of people required to fill employment demand, including expansion and replacement demand) in Scotland’s rural areas is forecast as 256,000 jobs, accounting for almost one quarter of the total requirement for Scotland. 90% of this will be in Mainly Rural areas. In terms of sector, total requirement will be greatest within:

  • wholesale & retail (51,800 jobs),
  • agriculture, forestry and fishing (33,500 jobs – which represents 76% of the total requirement for the sector across Scotland) and
  • administrative and support services (32,500 jobs).

In relation to the land-based sector specifically, the Plan notes the long-standing issue of the under-representation of women and their contributions in this sector with many roles un- or under-paid, and the need to address this in future to bring about positive recruitment change.

A key point is the higher tendencies for employers to report hard-to-fill vacancies in rural areas, and that rurality tends to exacerbate skills shortages, due to wider challenges around talent, attraction and retention, connectivity and training, and education provision[31]. Technical skills shortages were often reported, including in forestry and engineering, where there are national shortages, and in a range of core business skills, including management and leadership, mentoring and customer services.

The Plan outlines five priorities for future action, including:

  • achieving a better understanding of the sills that employers need and aligning provision to support this
  • providing individuals with accessible education and skills provision
  • developing the current rural workforce through upskilling and reskilling
  • building a secure pipeline for the future, and
  • taking a strategic coordinated approach to tackling skills in rural areas.

Appendix 8: Background information on the agricultural sector

The most recent statistics on the agricultural sector are reported in the main body of this report and this Appendix provides some additional background information about the sector.

Some 80% of Scotland’s land mass is under agricultural production, with 85% of Scotland’s land being designated as Less Favoured Area (LFA), meaning that there are challenges for agricultural production relating to soils, climate, topography, etc..

It is worth noting that, like businesses operating in many other sectors, agriculture, forestry and fishing sector businesses are experiencing significant challenges currently relating to the cost of living (or cost of doing business) crisis, including increased costs for fuel, fertiliser and food. More positively, businesses in general across the sector are adopting new technology and innovation, which is resulting in a demand for higher skills, including digital.

The UKCES (2016) report noted some of the wider drivers of change in the agricultural sector, including productivity improvement (including through investment in technologies) which will lead to decreased future labour demand and rising cost pressures – which have been exacerbated recently – which will encourage long-term efficiency savings and likely further reduce labour demand. Changes in consumption patterns were noted as an important driver of changing demand for agricultural outputs, including a shift towards substituting domestic and indeed ‘local’ products for imported foods, and a growing trend for eating out (though this may have been impacted longer-term by the Covid-19 pandemic). Overall however it was projected that the UK would remain a net importer of food and beverages. On balance therefore, modest growth in agricultural and fishery activity was expected to increase demand for domestically-produced foods and drinks, stimulating activity in agriculture and fishing industries.

Although now over a decade old, Lantra’s 2012 report is still relevant, noting the high levels of self-employment in agriculture, forestry and fishing (around 50% of the workforce in 2012), and the importance of seasonal working and unpaid family members (3% of the workforce, higher than the national average of 0.3%). The Lantra report also confirmed the dominance of male employees who significantly outnumber female employees (though it is worth noting that many females engaged in this sector may not be formally recognised as employees). It also confirmed that the workforce is ageing with a dominance of individuals from the white ethnic group (99%), a prevalence of skilled trades, elementary and managerial occupations, and a dominance of full-time workers (80%), with 19% part-time across the sector.

In terms of skill levels, the Lantra report noted that those working in the sector are on average highly skilled but poorly qualified and more likely to have no formal qualifications when compared to the rest of the economy. Around 53% of employers in this sector provided some form of on/off job training in 2011, compared to 59% across the rest of the economy but the sector is the third lowest in terms of employers providing training. This can be explained by a range of factors including high capital intensity, simple product market strategy, high levels of risk and uncertainty, high levels of variability of income, lack of regulated entry into jobs, high travel costs due to remoteness and lack of ICT infrastructure.

The Lantra (2012) report made a series of recommendations regarding priority areas for action relating to upskilling and entry, progression and sector careers, some of which were defined as ‘crucial’ and some as ‘other high priority’. The areas defined as ‘crucial’ included:

  • a need to ‘professionalise’ the sector (including to change perceptions and make it more attractive and to increase the number of people working in it with formal qualifications)
  • improved succession planning
  • environmental management
  • risk management
  • scientific knowledge and technology transfer, and
  • ICT to aid technological change.

It is interesting to see environmental management included in the crucial areas for upskilling more than a decade ago. Other areas included in the ‘other high priority list’ also showed recognition of the changing role of farmers encompassing activities beyond food production, including woodland management, practical conservation, marketing and market analysis, negotiation and influencing and public engagement in agriculture, forestry and fishing. The report concludes that the future workforce in agriculture, forestry and fishing would need to ensure a balance between high level technical and high level business management skills; this is particularly interesting when it is noted that agriculture is usually perceived as a low tech sector. It is not, however, clear is the extent to which these recommendations have been implemented as data is not available to evaluate the changing skills levels amongst the agricultural workforce. This is partly due to a lack of empirical data collected on this, but also due to the challenges mentioned previously, for example, the difficulty of collecting information from the many small businesses and self-employed contractors who operate across the sector.

Skills Development Scotland’s Sectoral Skills Assessments (SSA) provide detailed skills-related information for sectors across the economy. They are part of a wider suite of labour market information published by SDS. The most recent SSA for agriculture, forestry and fishing was published in November 2022. The SSA includes forecast data produced by Oxford Economics, about which SDS notes the following caveats:

  • forecasted data are based on what we know now and include past and present trends projected into the future.
  • the more disaggregated forecasts become, the less reliable they are likely to be.
  • their value is in identifying likely direction of travel rather than predicting exact figures.

Information from the most recent SSA is included in the main body of this report.

SDS’s Climate Emergency Skills Action Plan 2020-25 discusses the opportunities and skills implications of the climate emergency, including in relation to agriculture where emissions need to be reduced (agriculture and related land use in Scotland are the second largest source of net emissions after transport, although forestry makes a net contribution to reducing carbon emissions – the Climate Change Plan sets out a target of 24% emissions reduction from agriculture from 2020-2032), more peatland restored (250,000 ha of degraded peatland restored by 2030), trees planted (an increase in annual woodland creation to 18,000 ha a year by 2024) and biodiversity enhanced. In contrast to the SDS and Oxford Economics forecasts (and likely mainly due to the use of different definitions), the projection in the CESAP is for a decline in employment in the sector in future (by 5%, 4,600 jobs by 2029) but rising levels of productivity of 17% over the same period.

The CESAP notes a set of skills implications of these changes, including:

  • structural change and managing change to low carbon and regenerative farming will require management and technical competencies. Farmers and agricultural managers need the skills to undertake or commission the technical tasks required to reduce emissions.
  • precision agriculture will increase the demand for digital skills
  • upskilling and reskilling the workforce is critical
  • raising awareness of GHG emissions and skills required for their reduction is vitally important to ensure a sector-wide contribution to the net zero target. Such a ‘culture change’ in Scottish agriculture will form part of a ‘transformation pathway’ through which the sector can support the transition to net zero, as outlined by the independent inquiry on farming and climate change in Scotland.

Finally it is worth noting, as this is important later on for the scenario analysis, that the Scottish (and UK) Government has been criticised (see for example, the 2021 report on Towards Net Zero in UK agriculture, commissioned by HSBC, and WWF’s 2022 Land of Plenty report) for not doing enough in terms of a detailed future strategy for decarbonisation and net zero for agriculture, and indeed for wider land use activities, and for not having specific targets and associated investment plans for cutting emissions, the amount of land in low carbon/regenerative farming, etc. This lack of specific targets means that detailed and accurate forecasting work to identify likely future jobs and associated skills needs is challenging.

Box A2 provides some information, taken from the November 2022 SDS SSA, about recent developments across the sector to tackle skills issues.

Box A2: Examples of current skills provision for agriculture (taken from SDS SSA for Agriculture, Forestry and Fishing)

A range of organisations working in the agriculture sector are focused on improving skills and training across the sector. For example, the Skills for Farming Group is developing and delivering a range of interventions that are focused on supporting the skills needs of the industry and better articulating pathways into the sector. One project has focused on developing a Net Zero Toolkit to support the farming community towards net zero, signposting to areas of support and showcasing best practice. The Land-based Pre-Apprenticeship programme continues to build on its success by creating work placement opportunities for young people and the ambition to progress to Modern Apprenticeships. The Agriculture and Horticulture Development Board (AHDB) also has an Agriculture and Horticulture Skills Leadership Group.

SRUC is working closely with providers and staff to identify new opportunities for regional skills provision (e.g. in horticulture and net zero) across the land-based sector. It is bringing together its provision into a ‘Skills Academy for the Rural and Natural Economy’ which brings together all short course and CPD provision. It is also focusing on encouraging students to develop their entrepreneurial thinking and knowledge through its Enterprise Academy.

Meanwhile, Scottish Agricultural Organisation Society has launched an initiative to develop leadership capability within the sector. The Growing Tomorrow’s Leaders programme provides an opportunity to boost skills and knowledge to help support individuals to meet the challenges and opportunities.

Additional Data Sources

  • In terms of numbers of businesses, again drawing on data in Rural Scotland Key Facts 2021, 35% of SMEs in remote rural Scotland operated in the agriculture, forestry and fishing sector and 26% in accessible rural areas (2% in the rest of Scotland).
  • 56% of the agricultural workforce are farm occupiers who own or rent their farm and work on it; 40% of farm occupiers are female (2021 Agricultural Census). Ownership status (with over half of the current workforce strongly linked to ownership or rental of their land), and the opportunities for new people to take on the ownership or lease of farms, impacts on the ability of individuals to move in and out of the sector. Equally, the movement of people out of (and indeed into) the sector therefore has implications for land sales and ownership in rural Scotland.
  • According to the 2021 Agricultural Census, the average age of farm occupiers and the agricultural workforce is high, with 40% of male occupiers aged 64 or older (32% of females) and only 10% of working occupiers aged 41 or under. This demographic profile is important to understand when considering sector-specific interventions to address succession planning, upskilling initiatives, etc. Regular staff make up 31% of the total agricultural workforce, with the majority of these people working full-time.
  • By way of comparison, the Scottish Government’s 2020/21 report on Scotland’s Labour Market notes that 50% of the workforce in the agriculture, forestry and fishing sector is within the 50 and over cohort.
  • Work by SRUC in 2018 (conservatively) estimated that there were 9,255 seasonal migrant workers in Scottish agriculture in 2017; this number has reduced in recent years due to Brexit and other factors (which has likely had a knock on impact on production, in the fruit and vegetable sector, for example). Skills Development Scotland’s most recent Sector Skills Assessment for agriculture, forestry and fishing (published in November 2022) reported that, in 2021/22, the number of EU migrants working in the sector declined by 37.8 per cent compared to the previous year*
  • Data from the ONS for the whole of the UK reports that the agriculture sector had 129,000 self-employed people in 2022, accounting for approximately 3% of the total number of those in self-employment in the UK.
  • Data from the Scottish Government’s Agriculture Facts and Figures publication in 2019 shows that average weekly earnings in agriculture in 2018 were £460.98 (for regular full-time workers) with an average working week of 44.5 hours.
  • Despite the disparities in these data sources, data from the Agricultural Census suggests that the size of the agricultural workforce has been relatively steady over the past ten years (Figure 1).
  • The GVA from agriculture in 2020 was estimated to be c£1.4 billion (before support payments, and costs such as labour, rent, taxes and interest are taken into account), accounting for approximately 1% of Scotland’s total GVA. This is slightly higher than the equivalent figures for 2018 which estimated total income from farming in Scotland was £672million and the sector accounted for 0.8% of GVA in Scotland.
  • The sector had a forecasted GVA of £2,592 million in 2022, 1.7% of Scotland’s total economic output.

Appendix 9: Background information on the Forestry sector

As is the case with agriculture, the forestry sector is also reasonably well served in terms of sector bodies of different kinds, though perhaps not to the same extent as agriculture[32]. To reiterate, forestry is often grouped with agriculture (and fishing) for data purposes. Separating out these sectors in future would be useful in order to ensure we have a detailed understanding of them individually and together to inform future labour market needs.

As with agriculture, the research team undertook some additional analysis using publicly available data from the BRES to consider employment change in the forestry sector over the last 10 years. Figure A2 and A3 report the number of employees (total and full-time only) in the forestry sector by the RESAS Rural Urban Local Authority Classification between 2010 and 2021, respectively. Mainly rural local authority areas have the highest number of all employees and full-time employees in the forestry sector, and are responsible for most of the significant increase from 2020-21, followed by Urban with substantial rural areas. The number of all employees in Mainly rural areas increased by 44.75% between 2010 and 2021 (Figure A2) and the number of full-time employees also increased by 97.75% during the same period (Figure A3). In particular, the number of full-time employees in the forestry sector has significantly increased from 1,655 to 3,085 people between 2020 and 2021 in Mainly rural local authority areas. More work is needed to check whether or not this is a data anomaly or due to a specific and significant change in circumstance in the sector.

Approximately 18.5% of Scotland is currently under woodland and forest cover (1.4 million ha), an increase from around 5% 100 years ago (the EU average is 43%). Forestry values have been rising since 2000 (see for example, Forest Research 2022; Clegg and Tilhill 2021; Savills 2019), with Savills (2019) reporting that forestry investments have significantly outperformed other asset classes over the last decade achieving an average return of 15.8% compared to 5.6% for equities. McMorran et al. (2022) noted the sharp rise in land values which has resulted from the increase in forestry investment recently. This has resulted from a number of factors, including institutional investors and financial institutions entering the market looking for new environmental investments (including amenity, recreational and rewilding projects), global timber shortages (but the ongoing need for timber to meet house-building targets), and global policy drivers to reduce reliance on fossil fuels and achieve net zero, including through tree planting and woodland creation (see also McMorran et al. 2022). McMorran et al. (2022) noted that 2021 saw the largest ever annual investment in commercial forestry land with total investment in commercial forestry land in both 2020 and 2021 reaching just over £200 million, around double the levels seen in preceding years. Similar work by Knight Frank shows UK farmland values peaking in the mid-2010s and plateauing since (Knight Frank 2021).

The forestry sector is also characterised by a high proportion of workers with no formal qualifications and there is a prevalence of lower level qualifications (though skills are not always related to formal qualifications). The Forestry Skills Action Plan also notes confusion regarding industry standards for training as licenses can be obtained from different providers. The sector is somewhat fragmented with:

  • many diverse microbusinesses operating.
  • the high proportion of self-employed workers (which are not always measurable in key indicators).
  • the predominance of males over the age of 45 in the workforce.
  • the increasing use of tech.
  • increasing productivity.
  • lack of promotion of a wide range of careers and development opportunities in the sector.

More positively, the sector is becoming recognised as one which can provide a range of ‘green jobs’ within an expanding green economy, and the Action Plan assesses future skill needs within the industry, highlighting the need for technical, operational and strategic leadership skills, more support for new entrants to ensure a more diverse workforce, improving perceptions of the industry among young people, and ensuring succession planning and upskilling. What is not clear from the analysis undertaken here, however, is the levels of skills and qualifications amongst the (large number of) people joining the sector recently as reported earlier, nor where those people are coming from i.e. are they newly qualified young people for example, and/or are they older people/more experienced workers who moving into the sector from other sectors (either land-based sectors or other activities) who can draw on existing skills and/or need training in new skills.

Looking to the future, the Scottish Forest and Timber Technologies Group report from 2019 (Roots for Further Growth) sets out the scale of the future growth in the forestry sector, in particular relating to net zero and carbon sequestration and storage targets, the emergence of new products, including in textiles and biotech, and enhanced digitalisation and mechanisation.

Further considering future workforce requirements, Glaister (2019) was commissioned by Lantra and the Scottish Forest and Timber Technologies Skills Group to review the potential gap between the current trees and timber sector workforce and the capacity required to deliver its key target for woodland creation and forecasted increases in production and associated restocking. The report forecast growth across the sector to 2027 in order to undertake planned/forecast harvesting, restocking and new woodland creation programmes, and estimated an overall increase in employment required from 2017 to 2027 of 32% (or a total recruitment need of 72% if retirement and other factors are considered).

Glaister (2019) estimated the number of workers required to fulfil key roles in forestry, necessary to meet the target of 15,000ha woodland creation per annum in 2027 (the target has since been raised to 18,000ha). Firstly, industry work programmes for harvesting, restocking; new woodland creation; and primary processing were defined. Secondly, the level of resourcing that would be required to fulfil those work programmes (assessed as worker year equivalents) were estimated. Lastly those estimates were mapped to six forestry sub-sectors. Estimated employment requirements per sub-sector are given in table A5 below. Applying Glaister’s (2019) methodology, work by RDI Associates et al. (2021) on behalf of the Forestry Skills Forum for England and Wales, estimated a 51% increase in employment across all roles in the forestry workforce to 2025 and an 86% increase to 2030 on 2019 employment levels for England, and equivalent 72% and 63% increases for Wales respectively. Comparing the number of positions advertised annually on the ICF vacancy service they note a 441% increase from 2016 to 2021.

We further note a prior study by CJC Consulting (2015) which sought to quantify the economic contribution of the forestry sector in Scotland. Taking a relatively wide perspective[33] CJC Consulting (2015) estimate GVA and employment for three broad categories of forest industries; forestry and timber processing; forestry related recreation and tourism; and forestry related deer and game. They further estimate total employment arising from forestry related recreation and tourism as 6,312 FTE and GVA from this sub sector as £182.8 million. They note however that such figures may not be fully representative of the net contribution of the sector, as forestry related recreation may be expected to displace some proportion of other recreation possibilities. Adjusting for displacement they suggest a range of 4, 270 to 5, 840 FTE jobs created by forestry recreation and £120 to 164m GVA. These authors further estimate total employment arising from forestry related deer and game, with their definition including deer management for forestry, as well as sport shooting within a woodland habitat. Values for both are drawn from PACEC’s (2014) The Value of Shooting report. They assume that 25% of the total activity defined in the PACEC study can be attributed to forestry related deer and game. Applying this multiplier to the PACEC values they estimate total employment to be 2,260 and GVA from this sub-sector to be £68 million.

Westbrook and Ralph (forthcoming) develop a series of ten case studies in order to assess employment impacts from marginal investments in forestry (results summarised in table A6 below).

Discussing the nature of future job creation, they highlight that targets to increase forest cover “will potentially create substantial additional employment through [various forestry sub-sectors] planting, maintenance, felling, primary and secondary processing, and leisure and recreation forest usage.”

Following from their analysis they suggest that employment impacts will depend on:

  • Site characteristics; size of planted area, terrain, type and density of planting, whether new planting or restocking, whether access is improved, whether public access is encouraged, fencing needs;
  • Whether nursery stock is domestic or imported;
  • Share of tree cover achieved through rewilding as compared to conventional planting;
  • Investment in materials, machinery and equipment – whether this is labour productivity enhancing and whether sourced domestically;
  • Potential trade off with agricultural production – and scope for transfer of working time from agriculture to forestry

They further suggest that supply of workers wishing to enter the industry will be a constraint. To surmount this they suggest (i) increasing rates of pay, potentially through skill development and (ii) providing more multi- occupational opportunities, including farm diversification and encouraging community based forest ownership.

They highlight that median pay for forestry workers (£20,590) is substantially less than the UK national average (£29,577) and less than in other skilled roles involving machinery operation, including agricultural machinery drivers (£28,062), road construction operatives (£28,460) and mechanical engineers (£37,050).

Appendix 10: Background information on the game and wildlife management sector

This Appendix provides some background information on the game and wildlife management sector which is an important land use and employment sector in rural Scotland.

According to Lantra (2018), the game and wildlife management sector has two main purposes: protecting habitats and promoting biodiversity, as well as supporting tourism and recreation. Employees can work with a range of species; however, in Scotland they mainly focus on deer, rabbits and hares, and birds such as grouse, pheasant and partridge. There are three main types of gamekeeper: lowland, upland and highland, and although some principles of their work are the same they work in different ways and with different species. Gamekeepers could also be involved in deer and game rearing (with approximately 40 million game birds released each year in the UK). These two areas of work involve similar basic knowledge but have specific specialities.

A variety of organisations have undertaken work on the sector to explore its value in terms of contribution to the economy, and the number of employees and businesses in the sector, though as is the case with many of the other land-based sectors, the figures provided are different as a result of different approaches to data collection and to defining the sector.

Research carried out by Lantra in 2010 (reported in Lantra 2018) shows that the game and wildlife management industry played an important role in the environmental and land-based sector at this time, representing 9% (2,300) of businesses and 4% (5,300) of employees.

The industry employment base is mainly made up of seasonal or part-time jobs, meaning that it is very difficult to provide clear statistics on business size. It is known, however, that generally businesses are small across the sector. Work by SDS found that microbusinesses dominated the sector in Scotland, with 83% of the sector employing 0-4 people.

As the majority of businesses and employees are in remote locations, there is a reliance on staff being qualified with up-to-date technologies and practices.

A report by Lantra in 2011 on behalf of Scottish Natural Heritage (SNH) explored skills requirements in the game and wildlife management sector in Scotland. The sector was defined as involving the management of upland, lowland, woodland and wetland game and wildlife species, including partridge, grouse, pheasant and deer. Workers in the sector are focused on protecting habitats, promoting biodiversity, supporting tourism and recreation and providing a source of high quality meat. Game and wildlife makes a significant contribution to the Scottish economy, as well as contributing to the maintenance of Scottish moorland, which is a huge tourist attraction. SNH estimates that wildlife tourism has a value of £67 million to the Scottish economy. The British Association for Shooting Conservation (BASC) Scotland estimate shooting, stalking and angling to have a value of £136 million.

The Lantra report provides a range of information about the sector’s labour market in 2012 (more than ten years ago):

  • The game and wildlife sector workforce was male dominated (97.6%), with three quarters (75.8%) aged 45 or over.
  • The self-employed (39.4%) were slightly more prevalent than fulltime employees (31.4%) and part-time employees (29.2%).
  • Almost a third (29.2%) of survey respondents involved in the game and wildlife sector were found to be self-employed. Just over a third (31.4%) had a full-time involvement in the sector, and the majority (39.4%) stated that they worked part-time within the sector, mainly in a voluntary capacity.
  • Some 6.9% of respondents defined their involvement as ‘other’ which, when explored further, meant that these people had a small involvement in the game and wildlife area.
  • A substantial volunteer workforce (20%) supplemented the paid workforce within the game and wildlife sector.
  • Another 60% was made up of involvement in game and wildlife estates (24.9%), tenant farmers (12.7%), commercial forestry (11.8%), and private woodlands (10.6%).
  • Whilst there were 164 job titles listed by respondents, the sector was dominated by four key roles; those job titles with the word ‘keeper/deer manager/stalker’ made up nearly half of the respondents (48.3%).
  • Survey respondents were highly qualified, with 95.5% stating that they possessed a relevant qualification citing both accredited and non-accredited courses. Exploring this further found that almost 70% of respondents cited non-accredited but industry-recognised practical certificates of knowledge and competence. From this, it can be concluded that the sector’s workforce is highly skilled, but this is often developed through non-accredited training methods and knowledge transfer activities than full-accredited qualifications.
  • The majority of respondents (86.1%) recognised the importance of qualifications, and this was more prominent amongst the workforce who were full-time and in more senior roles.
  • Skills gaps were identified in the areas of IT, raising public awareness of the game and wildlife sector, and the higher-level skills related to conservation and ecological issues, such as habitat management.

The report put forward a series of recommendations related to the future workforce in this sector in Scotland (remembering that this work was undertaken in 2011-2012), including improving signposting and access to information on opportunities for training and CPD for those working in the sector, work to determine future skills priorities and where there are gaps, improved communication between those operating in the sector, more transparency about training on offer and accreditations, more courses that include the areas of conservation and technological change, support for the voluntary sector to keep up with the demands for greater professionalism, and greater promotion of the sector to young entrants, career changers and women.

A survey carried out by Public and Corporate Economic Consultants in 2014 on behalf of 17 organisations involved in shooting and conservation revealed that shooters spend an estimated £2.5 billion a year in the UK on goods and services. This produces a direct financial benefit to the UK – defined as gross value added (GVA) – of £2 billion a year. This survey indicated a need to ensure there are trained individuals to support this sector to maintain its influence on the economy.

The report also indicated that there were around 35,000 jobs directly supporting shooting and conservation in the UK. The industry also directly supports around 5,200 full-time jobs in the food and accommodation sector which helps to sustain rural communities in the autumn and winter when conventional income from tourism is likely to be reduced.

Work by Glass et al (2015) explored the socio-economic impacts of grouse shooting in two remote rural areas of Scotland, including the number of jobs (permanent and seasonal) and amount of spend and revenue linked to this activity in the two areas and wider community-level benefits, such as attendance at local schools by children of gamekeepers and their local spending in shops. Although most people answering the project survey in both areas felt positively about the impacts of grouse shooting in their area, the research highlighted that more work was needed to improve estate-community relationships. Some concerns were raised in both areas about the increased number of hilltracks that had been constructed and about illegal raptor persecution.

Thomson et al. (2018) reviewed the socio-economic impacts of driven grouse moors in Scotland and cite a range of estimates for employment linked to grouse moors.

They highlight that direct employment associated with grouse moors includes gamekeepers, shoot managers, other estate staff and seasonal and casual employees, while the industry further creates indirect employment in both upstream sectors which provide inputs and services, and downstream sectors such as game processing.

The key findings of their report note caveats which must be borne in mind when interpreting these estimates, and which bear repeating in full:

  • There is a narrow base of evidence that specifically focuses on the socio-economic impacts of grouse shooting, with some additional evidence relating to the wider game shooting or estate sectors. The dated nature of much of this research means that the social and economic impacts of more recent intensification of driven grouse moor management, on some estates, are missing from the evidence base. Therefore, industry-collated and reported data is often cited in contemporary discourse regarding grouse moor management.
  • Much of the commissioned research and industry-collated socio-economic evidence suffers from self-selection and self-reporting bias. The lack of a definitive dataset that includes all estates engaged in grouse moor management means that it is impossible to assess how representative research and industry data is of the whole sector.
  • The narrow evidence base and inconsistency in data collection approaches mean that evidence on socio-economic impacts is open to criticism. As most of the research has been commissioned by representatives of the grouse or wider estate sector, the objectives of the research have been criticised, by some, as only focusing on demonstrating the positive aspects of grouse moor management. However, despite the limitations, the existing evidence base does provide some context relating to the social and economic contributions of grouse moor management (see Table A7 for a summary of the employment impacts predicted by a number of studies of activities linked to grouse shooting and grouse moor management).

The study explored the potential impacts of moorland for grouse shooting being transferred to other uses, including forestry and woodland. The approach taken in this report is useful in informing the modelling work in this study.

Appendix 11: Background information on the nature-based activities sector

As noted in the main report, there is no single universally accepted definition of the nature-based sector. A report by Hirst and Lazarus in 2020 for NatureScot includes a defined set of nature-based solutions in a broad definition of nature-based jobs, including peatland restoration, woodland restoration, green finance, coastal ecosystems and sectors highly dependent on natural capital (the full text is provided in the main report).

  • Green finance
  • Urban green infrastructure, including planning, ecological engineering, active travel networks
  • Sectors highly dependent on natural capital (especially tourism and food and drink).

This broad definition is worth bearing in mind in relation to the CLBLR’s recent report which recommended consideration of using this ‘label’ for the land-based sector. The term nature-based sector is therefore a term that encompasses all of the activities we describe in this section of the report.

Despite a thorough search by the research team, NatureScot appears to be the only organisation generating evidence about the contribution of and labour requirements for the nature-based sector as a whole, and there are no representative organisations. The 2020 report for NatureScot by Hirst and Lazarus is the most comprehensive study of the nature-based sector that could be found and again the key points from this report are included in the main text.

Looking ahead to the future, Hirst and Lazarus (2020) argue that significant further growth is anticipated on the back of expansion in activities – including peatland restoration, green infrastructure and green finance, woodland creation, and blue carbon – required to meet our net zero targets by 2030 and 2045. They note that action needs to be taken now to ensure that we thoroughly understand and are aware of the skills and capacity needed for the nature-based sector in future. This is because there is a time lag before increased workforce capacity and upskilling works through the system. They argue that skills needs for this specific sector should be mainstreamed and aligned with skills policy, planning and delivery partners. NatureScot’s skills action plan for 2022-23 addresses some of these concerns about the future workforce and skills levels in the sector.

Several opportunities were identified for nature-based skills development by Hirst and Lazarus (2020), including a need to fill operational jobs more effectively, for which recruitment is often local and sometimes through sub-contracting arrangements. It was also noted that many businesses operating in this sector are micro or small with seasonal labour demands where costs and availability of training can be challenging. Workforce-sharing initiatives may be one potential solution to explore, where the costs of training and upskilling are shared amongst employers and jobs are created which are viable, year round jobs, also thereby reducing the potential for loss of employees to other sectors.

The location of many of these jobs in remote rural areas is potentially hugely beneficial for these communities, although many are experiencing shrinkage in their working age population (and have done so for decades), making the attraction of new people all the more important[34]. Finally, the report suggests that higher education institutes need to be engaged in ensuring that young people entering the sector have an appropriate blend of technical, digital and multi-disciplinary skills, including climate literacy and an understanding of natural capital.

Appendix 12: Seasonality

This section discusses the seasonality of employment in tree planting and peatland restoration. A significant expansion of activity in tree planting, and peatland restoration activity is required in order to meet net zero land use targets. In order for workers to fulfil these roles they must be able to secure sufficient income to cover housing and living costs. Whether this is through taking on a range of roles in the land-based sector, or within the wider economy, it is important to understand the seasonal working patterns as these pose a constraint to taking on further employment

Based on the sources that we have reviewed, we suggest that the main tree planting period in Scotland is October- March, excluding December and January and that the key busy period for peatland restoration is August to March (with interruptions due to winter weather). Due to having similar busy periods it seems unlikely that roles within tree planting and peatland restoration will be fulfilled by the same individuals.

Seasonality is a key aspect of many job roles within the land- based sector. Seasonal patterns in labour demand arise from various factors, including agricultural production cycles (e.g. lambing and fruit picking), seasonal increases in demand (e.g. tourism and hospitality), and seasonal restrictions on activities (for instance due to bird nesting restrictions).

The seasonal and part time nature of activities within the land based sector have been highlighted as a potential constraint to upscaling the labour force to meet net zero land use targets (Hirst and Lazarus, 2020).

While seasonal increases in labour demand can be important to rural economies, seasonality of employment can also create challenges. A reliance on insecure seasonal employment can exacerbate problems surrounding the affordability of rural housing. Responsibilities towards existing seasonal employment may also constrain workers ability to seek other employment, particularly affecting women.[35]

Seasonality of Peatland Restoration

The need to avoid disturbance to ground nesting birds is perhaps the key constraint to work in upland environments. NatureScot have issued the following guidance for managers and contractors working on peatland restoration;

“To reduce the risk of disturbance, it is recommended that, as a default approach, restoration work should be programmed to occur outside the main bird breeding season (April – July). Despite the recommended default approach, a blanket exclusion for restoration work undertaken during the bird breeding season [was not deemed] necessary and there will be circumstances where restoration work should be possible. This should only be done when active consideration of the likely consequences for breeding birds has been undertaken and can be demonstrated that work will avoid affecting sensitive species.” (Douse and Artz, 2022)

To this end NatureScot have developed a ten- point checklist. While there is no outright restriction on work during bird breeding season, meeting the conditions of the checklist entails further costs to contractors. It is unclear to what extent contractors are willing to bear these costs, or whether the April – July period is viewed as a de facto restriction.

Winter weather is another factor that will influence the number of days in the year on which restoration can be carried out. The arrival of winter weather, snow, ice and strong winds makes restoration work more challenging, while snow lying on the ground may necessitate site closures causing costly delays to contractors (Novo et al., 2021). [36] Sites at elevation in upland environments are most at risk of closure due to snow.

Peatland restoration must also be accommodated within wider estate management activities such as lambing, muirburn, deer stalking and grouse shooting which further follow seasonal patterns.

Seasonality of Tree Planting

Tree planting typically takes place over the winter when trees are dormant and less likely to be damaged. Winter planting when the ground is moist also allows the best chance of establishment before spring, though it is also important to avoid planting when the ground is frozen or too wet (The Tree Council, 2021).

Scottish Forestry (no date) indicate that trees are typically planted between October and March. Morgan (1999) meanwhile indicates that due to ground conditions planting should generally avoid December and January.[37] A range of estimates for the tree planting season are shown in Table 9 below.

The planting season is further constrained by the availability of seedling stock. Bare root stock is only available in the winter when trees are dormant. Container grown trees meanwhile may be planted all year round (The Tree Council, 2021).

Appendix 13: Summary of existing research work exploring future labour market and skills requirements

In this Appendix we review a number of research projects and programmes that the research team found that are exploring the size and shape of the current and future labour market and the current and future economic contributions of different activities. This review helped to inform the team’s thinking about the modelling approach to be used in this work.

A13.1 The UK Commission for Employment and Skills

The UK Government’s Commission for Employment and Skills (UKCES) Working Futures 2021-24 was a publicly funded, industry-led organisation providing leadership on skills and employment issues across the UK until it closed 2017. The UKCES undertook a programme of research including producing and updating robust labour market intelligence, through a number of ‘core’ products, including the Working Futures Series (see for example Wilson et al. 2020).

The Working Futures series from the UKCES was a quantitative labour market model that provided detailed projections of the size and shape of UK employment by industry, occupation (to SOC 2010 4 digit occupational categories), qualification level, gender and employment status for the UK, its constituent nations and for the English regions in the medium to long-term (up to 2024). The modelling of what the future might be like was based on past trends (see Wilson et al. 2016 for more detail on the technical approach, including the data used from the Labour Force Survey and the Census). One major advantage of the Working Futures forecasts is that they were based on a common and consistent economy wide overview of skill needs (as measured by occupation and formal qualifications), allowing detailed comparisons across sectors. This is based on a transparent, specific set of macroeconomic assumptions and economic relationships, affecting the whole economy and its structure.

The focus of Working Futures was on demand for skills as measured by employment, occupation and qualification, recognising that different jobs require different skillsets. Sectoral change is one of the drivers of changing demand for skills, and the projections are based on the use of a multi-sectoral, regional macroeconomic model, combined with occupational, replacement demand and qualifications modules. However, projections should not just be based on changing levels of employment by occupation which provide only part of the story about how the demand for skills is changing, but also on replacement demands. The latter recognises the significant outflows of those retiring from the labour market, or leaving for other reasons, such as for family formation, mortality, net occupational mobility and net geographical mobility. The model shows that, despite projected declines in employment for many occupations, there will be significant demand for the skills concerned to replace those leaving the current workforce (i.e. total replacement demand outweighs expansion demand).

As with all projections, the Working Futures analysis should be regarded as being indicative of likely trends and orders of magnitude, given a continuation of past patterns of behaviour and performance, rather than precise predictions of the future. The projections in Working Futures are based on econometric models and judgement, including with reference to a range of exogenous factors, including global economic trends, productivity levels, UK house prices, etc. and the results should be used in conjunction with other sources of intelligence about the labour market. The rationale for predicting future skills requirements is about better matching of labour supply and demand, in order to achieve better labour utilisation and higher labour productivity. The information produced from analysis like this is critical to policy-makers but also to individuals, education and training providers, and employers to inform policy development and strategy around skills, careers and employment.

Wilson et al. 2020’s recent work provided a benchmark for debate and thinking about the employment future given a continuation of past patterns of behaviour and performance. The overall outlook for changing employment levels and patterns by sector, occupation, qualification and geographical area show many similarities to those set out in the previous set of Working Futures projections. Thus, despite the uncertainties associated with EU exit many of the underlying trends regarding skills remain unchanged.

Working Futures was based on Cambridge Econometrics (CE)’s multi-sectoral dynamic macroeconomic model (MDM-E3) based on the UK government’s official data to provide a comprehensive and detailed picture as well as projections of the UK labour market, focusing on employment prospects for up to 75 industries, 369 occupations, 6 broad qualification levels, gender and employment status as well as economic contribution, including results for the devolved nations and the English regions. This model is normally used to analyse changes in economic structure and assesses energy-environment-economy (E3) issues and other policies. In MDM-E3, the key indicators are modelled separately for each industry sector and (sub)region, yielding results for the UK as a whole. It also disaggregates the UK into twelve regions, including Scotland. Due to the limitations of available data, currently in the MDM-E3 database there are 87 main employing activities distinguished at the UK level (and 46 for the regions), defined using the Standard Industrial Classification 2007 (SIC2007). It can be used for annual comprehensive forecasts to the year 2030 by sector, an in-depth treatment of changes in the input-output structure of the economy, detailed treatment of the interactions between energy generation, environmental emissions and economic development, scenario analysis, to inform the investigation of alternative economic futures and the analysis of policy for the UK as a whole and its regions, and so on (there is more information about MDM-E3 in the Technical report on sources and methods).

A13.2 SDS and Oxford Economics

While the Working Futures modelling work using Cambridge Econometric’s MDM-E3 model provided a common and consistent approach to analyse changes in different sectors, it is worth noting that there are other (similar) models available which will also do this. Skills Development Scotland (SDS) appointed Oxford Economics to provide labour market, sectoral, occupational and skills forecasts for Scotland, both nationally and regionally over the period to 2027. The forecasts provided are produced by Oxford Economics Local Authority District Forecasting Model. Results have been provided for Regional Outcome Agreement areas (ROAs), City Region Deal areas, local authorities as well as Scotland and the UK. The model is based on employment data from the Business Register and Employment Survey and six variables are provided:

  • Employment,
  • Occupational change,
  • Broad industry and sectoral change,
  • Total requirement including expansion and replacement demand,
  • Employment by gender and status, and
  • Demand for qualifications.

Oxford Economics Local Authority District Forecasting Model sits within the Oxford suite of forecasting models. This structure ensures that global and national factors (such as developments in the Eurozone and UK Government fiscal policy) have an appropriate impact on the forecasts at a local authority level. This empirical framework (or set of ‘controls’) is critical in ensuring that the forecasts are much more than just an extrapolation of historical trends. Rather, the trends in their global, national and sectoral forecasts have an impact on the local area forecasts. In the current economic climate this means most, if not all, local areas will face challenges in the short-term, irrespective of how they have performed over the past 15 years. The Oxford approach depends on three factors: global and national outlooks, historical trends in an area, and fundamental economic relationships which interlink various elements of the outlook. Importantly in the context of this work where the scenarios are guided by the policy targets, Oxford’s model provides projections on a ‘policy neutral’ basis. Unconfirmed, aspirational or policies at planning/development stage are not included. Though forecasts are built primarily around the economic relationships above, the use of local knowledge and published material on local development is required to augment the results of the formal modelling process.

SDS, based on the Oxford Economics model, provides a large quantity of information on future skills requirements by sector and by various geographies in their RSAs and SSAs.

Having reviewed these existing models which have been applied to the labour market in general, the appendix now turns to review employment and labour market work which has been undertaken for specific sectors. This is described in the text in the remainder of Appendix 12, and summarised in Table A6 at the end.

Studies of the current and future contributions of the nature-based sectors

The research team identified a number of studies which have sought to determine the contribution of nature-based sectors to the Scottish economy and to quantify nature-based jobs. Each have employed a similar approach, first identifying nature-based sectors within national statistics, then applying a weighting which reflects either the contribution of natural capital to the sector and/ or the proportion of activity which is assessed as sustainable. The studies have adopted varying conceptual definitions of nature-based activity, and varying approaches to weighting. This has resulted in differing sectoral compositions and a range of estimates for nature-based employment, although most are around 160,000 FTE (direct) jobs in nature-based sectors (c6% of Scottish employment), with further estimates of jobs in the wider supply chain (of 240,000 and 290,000).

Hirst and Lazarus (2020) note that jobs in the nature-based sectors are growing much faster than in the rest of the economy – up to five times the rate of all jobs in Scotland – and accounting for one third of total job growth from 2015-2019. Their work also looks at regional differences, noting that in remote and rural areas, the primary sector dominates in terms of nature-based activities, while in urban areas, nature dependent sectors, tourism and food and drink account for the majority of nature-based employment.

A study commissioned by NatureScot (then SNH) by RPA and Cambridge Econometrics employed IO modelling to assess the Economic Impact of Scotland’s Natural Environment (EISNE). Their approach started from the 128 level two industrial sectors identified in the Office for National Statistics (ONS) 2003 Standard Industrial Classification system (SIC). Employing various techniques they estimate the contribution of the environment to each sector resulting in a list of 26 sectors judged to have significant links to the environment (where they have assigned a greater than 20% weighting), which together comprise the nature-based sector.

They estimated the sectoral GVA by modelling a hypothetical closure of the nature- based sector. They estimate the direct contribution to intermediate demand as £3.9 billion excluding and £8.6 billion including wages in 2003. Further considering the indirect effect of such a shock through inter-industry purchasing (the Type 1 effect) they estimate the contribution of the sector to be £5.9 billion.

Further considering the induced effect of such a shock through changes to wages and household consumption (the Type 2 effect) they estimate the contribution of the sector to be £17.2 billion. From this latter value they estimate GVA per head at around £3,400 per resident per year. They note that these estimates are somewhat sensitive to their weightings (weightings reflect percentage reliance on the environment), acknowledging this they have sought to apply conservative weightings and as such they believe their estimates may under-estimate the real contribution of the sector. They estimate employment in 2003 as 154,000 jobs directly supported by the natural environment or 242,000 when further considering direct, indirect and induced employment.

Building on the EISNE study, in work commissioned by NatureScot, Hirst and Lazarus (2020) sought to make an assessment of nature-based jobs and skills in Scotland. After first updating to 2007 SICS these authors employed a new conceptual definition of nature-based activities provided by NatureScot, then reviewed and updated the weightings assigned in the EISNE report. Applying this new conceptual definition resulted in a number of sectors being excluded that had appeared in the prior EISNE report; namely, construction, membership organisations, sewerage and refuse disposal, and water supply.

Hirst and Lazarus (2020) obtained sectoral employment data from the Business Register and Employment Survey (BRES) and augmented this to account for ‘missing’ unregistered zero employee businesses, as the BRES excludes jobs in businesses not registered for VAT or PAYE. From their analysis they estimated that there were 166,721 FTE ‘nature based jobs’ in Scotland in 2019. They further estimated that jobs within the sector have grown by 12,031 (7.5%) since 2015, five times the rate of increase of all jobs (1.5%) and accounting for one third (31.7%) of all job growth during that period.

In research commissioned by SRUC, Biggar Economics (2020) define and quantify the scale of the natural economy. Conceptually they define the natural economy as those sectors in the economy that:

  • Use natural resources,
  • Conserve/ preserve natural resources, and
  • Rely on natural resources or on the natural environment.

To operationalise their definition, they start from industrial categories at level 2 as defined in the Office for National Statistics (ONS) 2007 SIC. As a first step they identify those sectors that comprise the primary sector:

  • agriculture,
  • forestry and logging (SIC 02),
  • fishing and aquaculture (SIC 03),
  • mining of coal and lignite (SIC 05),
  • extraction of crude petroleum and natural gas (SIC 06),
  • mining of metal ores (SIC 07),
  • other mining and quarrying (SIC 08), and
  • mining support service activities (SIC 09).

Then with reference to the Scottish Government IO Tables combined use table they identify those sectors which are particularly reliant on inputs from the primary sectors:

  • manufacture of food products (SIC 10),
  • manufacture of beverages (SIC 11), and
  • manufacture of wood and of products of wood and cork except furniture manufacture of articles of straw and plaiting materials (SIC 16).

As a last step they augment their definition to include broader sectors that would not necessarily be captured by a single sector:

  • tourism, and
  • energy (including renewable).

For purposes of reporting they remap to six sub-sectors:

  • tourism,
  • food and drink,
  • fishing and aquaculture,
  • agriculture,
  • energy (including renewables), and
  • forestry, logging and manufacture of wood.

Having identified relevant sectors they consider whether a weighting should be applied, deciding to apply a 40% weighting to the tourism sector. Their analysis finds that GVA within the sector is dominated by energy. They estimate that in 2018 the Scottish Natural Economy generated £29.1 billion GVA, more than a fifth of total Scottish GVA, while the Scottish Natural Economy excluding energy generated £8.3 billion GVA in 2018, around 6% of Scottish GVA.

They further find that the trend in GVA is dominated by changes within the energy sector. Including energy, they find that the natural economy shrunk by 18% between 2008 and 2018, while excluding energy GVA within the sector grew by 25% over the period, with the value of tourism increasing by 60% and agriculture increasing by 39%.

Considering employment, their analysis find that the contribution of the energy sector remains significant, though less stark. They find tourism to be the largest employer, employing 87,200 followed by the energy sector and agricultural sector both tied at 67,000. They estimate total employment in the natural sector as 290,100 in 2018, around 11% of Scottish employment, but with regional variations across the six sectors.

RSPB-commissioned work, undertaken by Dicks et al. (2020) assessed the economic costs and benefits of nature-based solutions to mitigate climate change. The study makes a cost- benefit analysis of nationwide implementation of three forms of nature-based solutions: peatlands, saltmarshes and afforestation. Alongside direct monetary costs and benefits, their analysis estimates changes to jobs and sectoral GVA, and these values are presented as additional indicators alongside the primary indicators of their cost-benefit analysis (net- benefit and benefit cost ratio).

Although the report does not explain how the scenarios were designed, the assessment of them within the analysis reflect the authors’ interpretation of the potential scale for nature-based activities across the UK. Changes to jobs and sectoral GVA are estimated by input-output modelling and are described here in the text and in Table A5.

Peatlands

The authors note that peatland restoration projects may be expected to have a positive effect on employment, through the creation of additional jobs both during the restoration phase itself, and in ongoing future operation and maintenance of the habitat. Furthermore, when considering upland peatland areas, jobs can be created in economically vulnerable and remote areas (Committee on Climate Change 2018).

Meanwhile, due to restoration projects jobs may be displaced from activities such as animal raising and agriculture. They consider that such job losses will be typically small for restored upland peatlands, as these are not generally used for intensive and profitable economic activities (Committee on Climate Change 2018). Table A4 below sets out the estimates for jobs created, which include jobs that are created as a direct result of the restoration project and ongoing operation and maintenance of the restored peatland, as well as within supporting industries (i.e. jobs within associated supply chains), and further jobs resulting from increased household incomes and consequent increased household spending.

They note that as part of its recommendations on how to improve the UK’s use of land to meet climate goals, the Committee on Climate Change has recommended that at least 55% of peatland are restored to good status by 2050 (Committee on Climate Change 2020a). Work by Glenk and Martin-Ortega (2018) found that this 55% equates to approximately 1.6m ha of peatlands across the UK, thereby potentially generating approximately 48,000 temporary jobs in the restoration phase and 112,000 job-years during a period of 100 years. The value of the increased job opportunities should be considered alongside the benefit-cost ratio described above.

Saltmarshes

They note that temporary jobs will be created to carry out the restoration activities (as set out in Table A4). These estimates include jobs that are created as a direct result of the restoration project, as well as jobs within supporting industries (i.e. jobs within associated supply chains), and further jobs created as a result of increased household incomes and consequent increased household spending.

Considering an estimate provided by (Adnitt et al. 2007), they note that in the UK, total salt marsh habitat is expected to shrink by 4.5% in the next twenty years due to climate change. If these habitats were to be restored, an additional 308 temporary jobs could be created in a low restoration cost scenario, 660 in a medium restoration cost scenario and 1,628 in a high restoration cost scenario.

Woodland creation

Woodland creation and restoration projects have a positive effect on employment, through the creation of additional jobs both in the restoration phase itself, and in ongoing operation and maintenance of the habitat. It should be noted that job losses may arise as a result of afforestation, typically associated with economic activities originally carried out on the habitat. Job losses are not directly counted in their analysis.

The IO modelling carried out within their analysis estimates that the upfront capital investment for afforestation can generate the estimates set out in Table A11 below. These estimates include job-years that are created as a direct result of afforestation and ongoing operation and maintenance of the woodland, as well as jobs within supporting industries (i.e. jobs within associated supply chains), and further jobs that result as a result of increased household incomes and consequent increased household spending.

Table A11 below summarises the employment related results to the work by Cambridge Econometrics in 2020.

Table A11: Job Creation (Jobs Supported) Within Nature Based Solutions Scenarios Assessed by Cambridge Econometrics (2020)

 

Jobs created (per 100 ha.)

Assessed Scenario

Job creation within Assessed Scenario

Peatland Restoration

 

 

 

3 temporary jobs during restoration

7 job years during ongoing operation and maintenance

The Committee on Climate Change (2018) recommends that at least 55% of peatlands are restored to good status by 2050. This has been estimated as comprising 1.6m ha (Glenk and Martina- Ortega, 2018).

48,000 temporary jobs during restoration

112,000 job years over a period of 100 years

Saltmarsh Restoration

14 temporary jobs during restoration in a low-cost scenario

30 temporary jobs during restoration in a medium cost scenario

74 temporary jobs during restoration in a high cost scenario

The spatial extent of salt marshes in the UK has been projected to shrink by 4.5% over the next twenty years due to climate change (Adnitt et al. 2007). The scenario considers if this habitat were instead to be restored.

308 temporary jobs during restoration in low restoration cost scenario

660 temporary jobs during restoration in a medium cost scenario

1,628 temporary jobs during restoration in a high cost scenario.

 

 

Woodland creation

25 temporary jobs to carry out plantation activities

 

6 job years during ongoing operation and maintenance

The Committee on Climate Change (2020) recommends the creation of 30,000 ha of new woodland in the UK.

7,500 temporary jobs during planting

 

1,800 job years over a period of 100 years

Summarised from Cambridge Econometrics (2020). Employment outcomes are expressed variously as the number of temporary jobs, and the number of job-years. The duration of temporary employment is not defined within the study. In each case job estimates reflect total jobs supported, and include both indirect jobs created in the wider supply chain and the induced effect on employment through re-spending of wages

The Scottish Government (2022) in collaboration with NatureScot examined the economic analysis of how local investment in natural capital can impact local economies, measured as output effect and jobs created in Scotland. Given the limitations of the Scottish Government’s the Input-Output (I-O) tables on the full local economic impacts and the Standard Industrial Classification (SIC) of natural capital sectors, the research team applied the I-O model to conduct the new I-O tables and create new multipliers using from the investment information from literature review and the online stakeholder engagement (e.g., labour cost, material cost, etc.). The multipliers were then calculated by using for direct, indirect, and induced effects for the output effect and job creation and for use in economic appraisal of four different types of local natural capital investments: the restoration of upland and lowland peatland, woodland creation and restoration, regenerative agriculture, and coastal habitat restoration. The results suggested that if the four natural capital investments could be achieved, this should enable the increased inclusion of local economic impacts in business cases, including output and job creation, and investment strategies as well as providing better policy decisions in the future for Scotland.

  • Estimates relating to net zero land use scenarios

Work undertaken by Vivid Economics (2020) explored the economic impacts of net zero land use scenarios. This work involved a social cost-benefit analysis of the Climate Change Committees net zero land use greenhouse gas (GHG) mitigation measures in the UK. Their analysis estimates the net benefit of fifteen land use options within forestry, bioenergy, agroforestry, peatlands, and agricultural practices. Net benefit is assessed on both a private (excluding non- market impacts) and social (including non-market impacts, such as avoided emissions) basis.

The analysis does not consider changes to employment, it does however provide a methodology for evaluating costs resulting from different land use activities such as peatland restoration. Alongside this it provides a detailed schedule of costs and an estimate of the level of work required to deliver the Climate Change Committee’s recommendations (15 in total). For peatland restoration, the report also includes an estimate of how much work is required.

  • Estimates relating to low carbon and renewable activities

It is also worth referring to a number of reports which have focused on defining and measuring low carbon and renewable activities. Allan et al. (2017) for example note that this presents conceptual (i.e. what’s included and what’s excluded), methodological and operational challenges (i.e. accuracy). The authors review three recent studies in Scotland which have sought to estimate jobs in the low-carbon and renewables sector, and to assess their relatively strengths and weaknesses, and propose that these jobs should be added to the IO tables. The ‘Low Carbon Strategy for Scotland’ projects the number of low carbon sector jobs required in future. Consoli et al. (2016, p1056) argue that “better estimating of green job numbers and identifying patterns of growth (or indeed decline) is important to ensure effective local responses – such as adapting regional skills policies and provisions”.

Markaki et al (2013) applied I-O analysis to estimate clean energy investments by industrial sector and to calculate the macro-economic impacts of these green investments on production and employment in the Greek economy between 2010 and 2020. They produced the I-O table to compute the direct, indirect and induced production and employment effects associated with the selected energy conservation measures (e.g., the promotion of renewable energy technology, etc.). Their results demonstrated that the investments required for energy conservation projects would total €47.9 billion between 2010 and 2020. These investments resulted in an annual average gain of €9.4 billion in the national output with a creation of 108,000 full-time equivalent employment during the same period. The result also showed that the employment produced per €1 million investment in energy saving initiatives in buildings and transportation is considerably greater compared to the development of renewable energy sources in the power generation sector.

RPA and Cambridge Econometrics (2008) The Economic Impact of Scotland’s Natural Environment

 

NatureScot Commissioned RPA and Cambridge Econometrics to determine the current value of economic activity generated by the natural environment, at national and regional level, and associated employment both direct and indirect.

Nature Based Activity

 

  • activities concerned with the protection, restoration and enhancement of the environment;
  • activities that make sustainable use of one or more elements of the environment as a primary resource; (note on this basis they exclude quarrying and mining)
  • activities which are dependent upon the quality of the environment, in particular tourism and recreation and supporting industries; and
  • activities indirectly dependent on each of the above.

 

They consider each of the 128 industries at level 3 in the 2003 SICS. They estimate the extent to which activity within that industry depends on sustainable use of the environment. They further define an environment sector, and attribute to it those flows deemed sustainable. They model a hypothetical closure of the environment sector.

For each of the 128 industry groups in the 2003 Standard Industrial Classification (SIC), an estimate has been made of the extent to which each sector relies on and/or utilises the natural environment. In particular, consideration has been given to the need for a high quality environment, rather than exploitation of the environment. Thus, industry sectors such as mining and quarrying, although they use the natural environment for their primary resource, are assigned a dependence/link of zero per cent, since they do not rely on, or contribute to (in the short-term at least), a high quality environment.”

They identify 26 industry sectors that have significant links to the environment (where a significant link is defined as 20% or more of a sector’s activities being environmentally-related). These sectors include food and drink production, water use, timber production and use, tourism and recreation. In full, these 26 sectors are: agricultural/forestry machinery, agriculture and hunting, beers and ales, bread, rusks and biscuit, construction, fish and fish products, fishing and fish farming, footwear, forestry harvesting, forestry planting, fruit and vegetables, grain mill products, hotels and restaurants, meat and meat products, membership organisations, other food products, prepared animal feeds, recreational activities, sewage and refuse disposal, soft drinks and mineral water, spirits and wines, tanning and leather, tour operators, travel agents, vegetable/animal oils and fats, water supply, and wood and wood products.

Direct contribution to intermediate demand: £3.9 billion excluding wages and £8.6 billion including wages.

 

Further considering the indirect effect (the Type 1 effect) they estimate the contribution of the sector to be £5.9 billion.

 

Further considering the induced effect (the Type 2 effect) they estimate the contribution of the sector to be £17.2 billion.

 

They estimate nature-based employment in 2003 as 154,000 jobs directly supported by the natural environment or 242,000 when further considering direct, indirect and induced employment.

 

 

Biggar Economics (2020) Scotland’s Natural Economy Sustainable Growth Potential

 

SRUC commissioned Biggar Economics to define and quantify the scale of the natural economy.

“The natural economy”

 

They note that if broadly defined could encompass all economic activity, they seek a narrower definition on basis of activities that:

Use natural resources

Conserve/ preserve natural resources

Rely on natural resources/ the natural environment

 

Biggar Economics does not apply a sustainability weighting, except to tourism. The natural economy is the primary sectors plus those sectors that are particularly reliant on inputs from the primary sectors.

 

They start from industrial categories at level 2 as defined in the Office for National Statistics (ONS) 2007 Standard Industrial Classification System (SICS). As a first step they identify those sectors that comprise the primary sector:

  • agriculture;
  • forestry and logging (SIC 02);
  • fishing and aquaculture (SIC 03);
  • mining of coal and lignite (SIC 05);
  • extraction of crude petroleum and natural gas (SIC 06);
  • mining of metal ores (SIC 07);
  • other mining and quarrying (SIC 08); and
  • mining support service activities (SIC 09).

 

Then with reference to the Scottish Government Input- Output Tables combined use table they identify those sectors which are particularly reliant on inputs from the primary sectors:

  • manufacture of food products (SIC 10);
  • manufacture of beverages (SIC 11); and
  • manufacture of wood and of products of wood and cork except furniture manufacture of articles of straw and plaiting materials (SIC 16).

As a last step they augment their definition to include broader sectors that would not necessarily be captured by a single sector:

  • tourism; and
  • energy (including renewable).

For purposes of reporting they remap to six sub- sectors:

  • tourism;
  • food and drink;
  • fishing and aquaculture;
  • agriculture;
  • energy (including renewables); and
  • forestry, logging and manufacture of wood.

Their analysis finds that GVA within the sector is dominated by energy. They estimate that in 2018 the Scottish Natural Economy generated £29.1 billion GVA, more than a fifth of total Scottish GVA, while the Scottish Natural Economy excluding energy generated £8.3 billion GVA in 2018, around 6% of Scottish GVA.

 

Considering employment, their analysis find that the contribution of the energy sector remains significant, though less stark.

They find tourism to be the largest employer, employing 87,200 followed by the energy sector and agricultural sector both tied at 67,000, food and drink 46,900, logging forestry and manufacture of wood 12, 900, fishing and aquaculture 6,700, and mining 2,400.

They further find substantial regional variation in employment across the six sectors.

 

Hirst and Lazarus (2020) Supporting a Green Recovery: An initial assessment of nature- based jobs and skills.

 

NatureScot commissioned Hirst and Lazarus (2020) to provide an evidence base and short initial assessment of future employment opportunities related to investment in natural capital and the skills

required to do them as part of the green recovery and transition towards a net zero

economy.

They define the nature-based sector as including:

  • Nature-based activities, such as nature-based solutions, land use, marine management & fisheries, green finance, urban green infrastructure, as well as
  • sectors highly dependent on natural capital, such as tourism and food and drink (also called nature-dependent sectors).

 

Renewable energy generation was excluded from this assessment.

 

 

Hirst and Lazarus update the prior RPA and Cambridge Econometrics report.

 

Start with 2007 SICS.

 

Review sectors included in EISNE report, make adjustments on basis of NatureScot definition of nature- based activities.

 

  • nature-based solutions; (peatland restoration, flood risk management, blue carbon and the restoration / management of coastal ecosystems, woodland restoration, management of invasive non-native species – INNS);
  • low carbon and regenerative land use (including agriculture, forestry, wildlife management)
  • sustainable marine management and fisheries
  • environmental green finance (that excludes renewable energy generation)
  • urban green infrastructure, including planning, ecological engineering, active travel networks,
  • sectors highly dependent on natural capital (especially tourism and food & drink)

 

They obtain sectoral employment data from the Business Register and Employment Survey (BRES) and augment this to account for ‘missing’ unregistered zero employee businesses, as BRES excludes jobs in businesses not registered for VAT or PAYE.

 

They adjust and apply the sustainability weightings from EISNE report.

 

They estimate that there were 166,721 FTE ‘nature based jobs’ in Scotland in 2019. They further estimate that jobs within the sector have grown by 12,031 (7.5%) since 2015, five times the rate of increase of all jobs (1.5%) and accounting for one third (31.7%) of all job growth during that period.

Appendix 13: Reviewing approaches to scenario creation

A13.1 Scenario Planning

Scenario planning (or scenario analysis, scenario prediction or scenario method) is a technique used in many contexts, usually as a means of strategic planning using a systems-based approach to make flexible long-term plans. It can take into account the often complex relationships between factors, but has been criticised for its inability to take account of disruptions to the plans and for too often being regarded as making predictions rather than as a means of envisaging and thinking through the potential impacts of various plausible futures. However, scenario planning is widely regarded as a useful technique to help a range of different stakeholders – including policy-makers, businesses, communities, etc. – to anticipate change and prepare more robust strategies to respond. It can be used at different stages of the policy cycle from agenda setting to policy design, policy implementation and policy review. Scenarios can be developed based on expert judgements or wider participatory approaches involving stakeholders.

It is important to remember that scenarios are descriptions of potential plausible future conditions. They are not forecasts but rather images of how the future can unfold (Mahmoud et al. 2009).

Dunkerley et al’s (2022) work on ‘Labour market and skills demand, adopting a horizon scanning and scenarios approach’ contains some useful reflections on the value of scenarios work in the context of labour market studies, and the need to include both quantitative and qualitative data in this work. The objective of their work was to scan the horizon of the labour market over the next 15-20 years, to identify the drivers and emerging trends and to create five different scenarios of what the labour market could look like in future. They acknowledge that, while quantitative projections are available (see for example the Working Futures modelling by Wilson et al. [2020]), even if they are robust, they have limitations and are not sufficient alone. For one thing, they do not adequately take into account the many external factors that shape the labour market, which are often characterised by great uncertainty and disruption. This can make planning effective policy intervention aimed at supporting skill development, for example through the right investments in education and training, challenging. Qualitative scenarios can complement these assessments as they can draw on a wider range of factors than can easily be considered in a quantitative framework (see also Störmer et al. 2014 for a qualitative approach to scenario planning).

In their work, Dunkerley et al. (2022) take a mixed method approach including an evidence review, stakeholder interviews, qualitative scenario development and a scenario workshop. From a structured process of examining the most important variables that influence the labour market and skills demand, they developed five qualitative, high-level scenarios for the labour market using a structured approach to reflect uncertainties in the economy, the environment, technology and the wider societal, political and legal landscape, looking 15-20 years into the future. The five scenarios, which are not focused on specific sectors but provide a high level view of the labour market, with the implications for specific sectors drawn out, are:

  • Digital greening,
  • Living locally,
  • Protectionist slowdown,
  • Continued disparity,
  • Generating generalists.

In terms of the importance of undertaking scenarios work, the authors argue that the purpose of scenarios is not to predict – they are not forecasts or likely predictions – but rather it is to help decision-makers envisage different possible, plausible futures and to support them in assessing which policy levers might be useful under which circumstance. Accordingly, scenario building can be a useful policy planning tool as policymakers can envision different kinds of possible futures and consider different policy levers to address these possible futures. Their development is reliant on the existing evidence base, expert opinion and current thinking on what is plausible.

From their research, Dunkerley et al. (2022) draw a number of implications which are useful context information for the scenarios in this project:

  • ICT/digital skills are critical to the future of most jobs.
  • Any future vocational education and training system needs to provide clear and more flexible pathways so that workers are well aware of training options and can make informed decisions about what to do and how to do it.
  • More flexible, portable training with corresponding micro-credentials could be accompanied by accreditation and licensing of providers to mitigate the risk in quality of qualifications obtained in this way.
  • A broad range of stakeholders should be involved in developing courses and training to meet local labour market demand.
  • Education and training system also need to teach broad concepts and foundation skills (for example communication, networking, problem-solving, literacy and numeracy skills).
  • Employer investment in training will be increasingly important, but employer unwillingness to train their workers will continue to be a barrier. Incentives for life-long learning, both for the employer and employee, will be increasingly important, as will information on the benefits and options outlined.

Dunkerley et al. (2022) also argue that scenario development is not free from, and indeed heavily relies on, expert knowledge and judgements made by the researchers involved. As such in their work, they combined researchers with labour market and skills expertise and scenario specialists. In their work they had a structured six-step process and a ‘systematic framework’ (Gausemeier et al. 1998) which identifies critical factors and combines cross-impact analysis, consistency analysis and cluster analysis to identify scenarios.

Bishop et al. (2007) also review approaches to scenario development. While recognising the popularity of the Royal Dutch Shell method (which they note has been described as the gold standard) they urge practitioners to look beyond this and consider the applicability of a wider suite of approaches. They describe the following broad scenario planning techniques:

  • Judgment (genius forecasting, visualisation, role- playing, Coates and Jarratt)
  • Analytically looser process relying primarily on the judgment of the practitioners, lacks the methodological structure of other approaches.
  • Baseline / expected trend extrapolation
  • Defines one and only one scenario, the expected trend or baseline which is then extrapolated.
  • Elaboration of fixed scenarios
  • Starts from pre- determined scenarios. Practitioners then elaborate the implications.
  • Event sequence and probability trees
  • Considers the probability of key events occurring, highlights contingent events and maps as a probability tree.
  • Backcasting
  • Retrospective analysis.
  • Dimensions of uncertainty
  • Develops a matrix based on different dimensions of uncertainty. Scenarios are built from each element.
  • Cross impact analysis
  • Develops matrix of potential outcomes and specifies individual and conditional probabilities. By setting threshold value (for event to be said to occur) and iterating the model many times probability distributions can be estimated.
  • Modelling
  • Scenarios are determined based on differing combinations of model parameters and then implemented in the model.

Fergani (2021) discusses three prominent methods of scenario development (see Table A13).

Table A13: Summary of prominent methods of scenario development (adapted from Fergani (2021)

Method

Applicability

Royal Dutch Shell Method

  • Step 1: Identify Driving Forces of Change
  • Step 2: Distinguish “Predetermined Elements” and “Critical Uncertainties”
  • Step 3: Create 2- 4 Scenario Narratives through Dialogue. Asking how would the driving forces, predetermined elements and critical uncertainties behave in this or that scenario?
  • A key feature is iteration.

Historically the most popular method for scenario development, an open ended, loose process involving iterative discussion, can be time intensive.

4 Archetypes Method

  • Utilises 4 Archetypes: Continued Growth, Collapse, Discipline, Transformation
  • Step 1: Identify Driving forces of Change
  • Step 2: Specify Direction of Change
  • Step 3: Considering 4 predetermined Archetypes ask: How would the driving forces behave together in this narrative?
  • Step 4: Based on these interpretations develop scenario narratives.
  • Need to think of counter intuitive behaviour of driving forces and support this with references.

Quick. Necessary to consider whether archetypes are all relevant to the study context.

Similar to the three horizon’s method developed by Sharpe et al. (2016)

2 by 2 Matrix

  • Step 1: Identify Driving Forces of Change
  • Step 2: Driving forces clustered based on degree of mutual influence
  • Step 3: Identify Extreme Limits for clusters (factors)
  • Step 4: Rank factors based on impact and uncertainty
  • Step 5: Identify two most significant factors
  • Step 6: Create 2 by 2 Matrix

Structured process. Requires that uncertainty be reduced to two key factors, may be challenging to justify choice.

Dunkerley et al. (2022)

  • Step 1: Identify Driving forces of Change
  • Step 2: Cross Impact Analysis
  • Step 3: Future Projections
  • Step 4: Consistency Analysis
  • Step 5: Cluster Analysis
  • Step 6: Scenario Narratives

Structured process. Several stages of analysis, may be time intensive.

Bishop et al. (2007) question the reliability cross impact analysis based on practitioner judgement.

A13.2 Identifying drivers of change and sources of uncertainty

As identified here, there are various approaches to designing scenarios, but all start with the same first step: identifying drivers of change/key sources of uncertainty in the system.

We can identify some of these drivers/sources of uncertainty affecting the wider UK and Scottish economies here:

  • Demographic ageing,
  • Digitalisation,
  • National and international politics and economics (e.g. the war in Ukraine),
  • Lifestyle and working changes associated with the Covid-19 pandemic,
  • Climate change mitigation/adaption,
  • Energy transition,
  • Shift to a service based economy,
  • Increasing inequality,
  • Brexit,
  • Trade with Europe and the rest of the world,
  • The cost of living crisis,
  • War in Ukraine,
  • Government decisions and policy e.g. on inflation, interest rates, monetary policy and fiscal policy.

It is also possible to identify a list of drivers/uncertainties more specifically related to the land-based sector, which may result in unexpected/unintended consequences in terms of land use and land management and which may make achieving these ambitions more difficult, including:

  • Policy changes e.g. in terms of the replacement for CAP support, land reform, changes to agricultural tenancies, circular economy ambitions, etc.,
  • Mechanisation and digitalisation,
  • Land ownership and succession issues,
  • Rising Land Values, impacted by:
  • Fiscal incentives: IHT/ CGT reliefs,
  • Emerging Carbon and Natural Capital Markets,
  • High timber and forestry values,
  • Demand for plantable land,
  • Demand for peat,
  • Green Lairds/ Rewilding/ ESG,
  • Rising demand (and support) for (bio)energy crops,
  • Nutrition and diet transitions,
  • Changes to agricultural advice arrangements and associated research activities.

A.13.3 Other issues considered by the research team in developing the scenarios

There are a number of other issues which need to be considered when designing scenarios for the future of the land-based sector and these were discussed int his project with the Steering Group and also on a one-to-one basis with individual stakeholders.

First of all, the likely trade-offs between sectors as Scotland moves towards achieving the CCPU targets, which will require assessments of the net effects on jobs in different sectors.

  • Scottish Government tree planting targets may involve trade-offs with jobs in agriculture:
  • Woodland creation targets seek to increase woodland cover from 18% (as at 2019) to 21% by 2032, through a tiered increase in the planting rate reaching 18,000ha per annum from 2024.
  • Around 80% of land in Scotland is used by agriculture.
  • There may be capacity to increase woodlands on farms without displacing agricultural production. Agroforestry, shelter belts and other forms of on farm woodlands are actively encouraged. The recent Land Reform Consultation proposed a Land Use Tenancy which seeks to reduce barriers to tenants wishing to diversify from agriculture.
  • However, recent SRUC research has highlighted that larger scale conversion of agricultural land to forestry is already a feature of the market, as current high forestry and timber values have enabled forestry buyers to outbid for marginal hill land and increasingly for lower quality arable land (McMorran et al., 2022). This may result in jobs being displaced from sheep farms (agriculture) or grouse moors (sporting estates which employ game keepers) for example.
  • Increasing management of uplands for peatland carbon (a key policy priority for Scottish Government) may involve trade-offs with jobs on sporting estates and in sheep farming:
  • The Rural Land Markets Insights Report 2022 highlighted shifting motivations for estate acquisition, a decline in sporting motivations, linked to legislative changes and negative social perceptions of driven grouse shooting that exist among some stakeholders, alongside a parallel increase in landscape scale rewilding motivations and peatland carbon as an investment prospect.
  • There is uncertainty around the extent to which a change in upland management in line with such motivations could coexist with / displace traditional sporting jobs.
  • Meanwhile land management for peatland carbon requires control/ exclusion of grazing and can be expected to impact on revenues in sheep farming with knock on implications for employment (Aitkenhead et al., 2021). The degree to which revenues are likely to be influenced depends on stocking densities which vary across the country.
  • Scotland may evolve towards a more multifunctional vision of land use as many activities are seasonal:
  • For example, tree planting is seasonal, usually from October-March, and predominantly from January to March.
  • Some peatland restoration tasks are seasonal (due to bird restrictions), and heavy machinery tasks may not be feasible where there is snow cover.
  • Seasonality may result in more job churn if workers seek to transition to more secure year-round employment across different sectors.
  • One vision is that former sectoral distinctions become less pronounced and a general pool of land-based workers transition between roles as seasonal demands require.
  • This would require a significant shift in work cultures not least to incorporate more dynamism and flexibility and there may be cultural/ social barriers to this, as well as limitations in terms of generic v specific skills. For example, can one individual hold the range of skills required to undertake peatland restoration, tree planting and wind turbine installation and maintenance (and what is the range of skills required)?

A second broader issue worth considering is the extent to which Scottish Government targets will create jobs in rural areas and/or in urban areas. Some of the jobs created in the renewable energy sector for example are more likely to be in urban centres than in rural locations. Moreover, the structural challenges in rural communities (such as lack of affordable housing and poor transport connectivity) highlighted by this work as potentially providing barriers to people taking up new opportunities in rural communities also mean that people may need to live in urban locations to undertake rural-based work. This means that the value generated by this employment, if a residence-based approach is taken, may be recorded in urban rather than rural locations.

  • Sector-based or holistic scenarios?

It is possible to formulate scenarios which are holistic, i.e. involve targets relating to more than one sector, which are more likely to represent reality in terms of the inter-relationships between different sectors. However, this may not be specific enough to implement using an I-O model. For example, while the CCPU includes specific policy targets for forestry and peatland restoration activities, the ambitions regarding low emission agriculture and nature restoration activities are not clearly specified.

For example, rather than having a simple scenario based only on the target for woodland planting, the scenario could include multiple land use changes, such as an increase in woodland planting, peatland restoration, low emission farming and nature restoration activities. The latter might be described as more of a narrative based scenario (see for example Dunkerley et al. 2022).

An example of a narrow, specific scenario would be:

  • “An increase in woodland creation is required as per the Climate Change Plan Update to deliver 18000 ha per annum by 2024/5, rather than the current level of 12,000 ha per annum. This will require an increase in the number of people employed in the forestry sector.”
  • “An increase in peatland restoration work is required as per the Climate Change Plan Update to achieve a target of 250,000 ha of degraded peat restored by 2030. This will require an increase in the number of people employed in activities related to peatland restoration.”

An example of a more holistic, narrative scenario with or without targets could be:

  • “By 2030/2045, Scotland aims to be planting 18,000 ha of woodland per annum, restoring 250,000 ha of degraded peatland, having X% of its agricultural activity/X% of its agricultural land following low emission and regenerative farming practices, and to have X people involved/£X invested in nature restoration activities.
  • “Future landscapes in Scotland’s rural areas will comprise more peatland restoration, woodland expansion and nature restoration, with an increase in low emission agriculture. Creating and maintaining such a multifaceted land use system requires a workforce which includes individuals with a range of land use and land management skills.”
  • “Future rural economies in Scotland will be thriving and based around woodland creation, peatland restoration and biodiversity, sustainable tourism, energy and food and drink”.

We also considered whether the scenarios – irrespective of whether they are based on one or many sectors – could have three ‘levels’ i.e. achieving the CCPU policy target by 2030/2045, not/under-achieving the target, or going beyond the target.

The team also considered the potential to have regionally-focused scenarios, for example:

  • “Dumfries and Galloway already has X ha of woodland and forestry and local provision (e.g. through SRUC) for training and skills development in this sector. This area could deliver ?% of Scotland’s future woodland/forestry land use, but this would require an increase in employment in the sector of X people across the region, with a focus on X, Y, Z skills.”

The decision on the approach to take was informed by discussion with Scottish Government research analysts and policy officials and the availability of appropriate data, and whether or not they could be implemented using the IO modelling approach. The team also reviewed scenario-based approaches used in other similar studies. One example is the 2020 Vivid Economics report which identifies 15 options across five different land use options (forestry, bioenergy, agroforestry, peatlands and agricultural practices and technology) and four scenarios (business as usual, net zero, high mitigation uptake and technology push).

Focusing on future possible land use changes rather than changes in employment, Thomson et al. (2018) identified five scenarios that they argued are technically feasible up until 2050:

  • Business as Usual (BAU): Current trends in human diet, land use and management continue to 2050.
  • High Mitigation Uptake: Agricultural land is spared as a result of a reduction in food waste, changes in diet away from red meat and dairy products, increased yields and improved agricultural practices: this land, is converted to forestry, energy crops and agroforestry. Some peatlands which are currently used for agricultural purposes are either permanently rewetted or partly rewetted by raising the water table. Wholly rewetted peatlands are partly restored to semi-natural vegetation.
  • Technology Push: There is high uptake of mitigation practices and technological development in agriculture together with high levels of change in diet away from animal products, which are replaced with plant-derived food and other protein sources (e.g. synthetic and cultured meats) as well as large reductions in food waste. The land spared is afforested and used for biomass fuel crops, and there is some peatland restoration. This scenario also includes some multifunctional land use, e.g. agroforestry and re-instatement of hedges around field boundaries.
  • Multifunctional Land Use: Reduction in food waste and dietary change away from red meats and dairy products combined with improved agricultural practices allows higher uptake for agroforestry and medium levels of afforestation, along with some increase in the area of biomass fuel crops.
  • Maximum food production: Human diet retains current intake of meat and dairy products. Improvements on agricultural practices and yields increase food production per ha, but land remains in agricultural use rather than being re-purposed.

Further comments from the Project Steering Group on the scenarios

A number of other comments were also received from the Project Steering Group at the interim meeting and at meetings before and since this, to inform the team’s scenario-related work and these are summarised here. Overall, they demonstrate the complexity of work which aims to predict future employment change when (a) there are gaps in existing data and (b) there are a number of inter-related issues that will affect future employment, including levels of pay, seasonality of activities, the potential for multiple job holding, etc.:

  • It may be valuable to have reference to specific numbers rather than generic as this could be useful to determine the likely requirement for training and development of the skills and skill provision in these sectors, such as peatland restoration and woodland restoration/creation. On the other hand, steering more towards generic scenarios would be more useful as there are still significant unknowns as to the specific trajectories but we do know that the ‘more’ and ‘change to existing jobs’ projections will be highly likely.
  • It may be useful for the scenarios to include upland and lowland deer management – it’s still early days but there may some labour market effects as a result of the recommendations from the Deer Working Group report in relation to the sector, and of course this is likely to have implications for the woodland and peatland restoration aspirations. The team considered that to meet woodland creation targets would require some assumptions about deer control, either through significant fencing requirements or through reducing deer numbers, both of which would have implications for jobs.
  • The option of targeting one (or more) scenarios to specific regions (e.g. Dumfries and Galloway) on the basis of their existing land use pattern (e.g. a large amount of land already under forestry and woodland) was considered. However there was a concern that as scenarios are often (mistakenly) understood to be predictions, the work could take a more regional/micro look at the changes, which would then help to expose difficulties around the geographic location of workers and low rates of movement within the country. If there was a focus on one region, it would be useful if the model could be ‘re-used’ for another region. Any model would need to take into account wider factors/characteristics of the region including housing, infrastructure, differing land uses/qualities, etc.
  • It was suggested that having one or two sector specific scenarios might be helpful for 2030 and 2045 (e.g. relating to forestry and woodland creation and peatland restoration) plus two or three more general scenarios (e.g. high timber production, natural capital focused scenario). It was also noted that the latter may be a more appropriate reflection of the future labour market where people will need to deliver to a range of land uses and land management with a range of skills. At the same time, it was commented that data still tends to be sectoral in nature which is a key limitation in terms of calculating the future workforce needs and skill sets through the scenario analysis.
  • How will modelling take into account changes in the types or ‘quality’ of jobs available, gender and age differences (note the high average age of farmers and the often unrecognised role of women in agriculture) and also the role of the unpaid – and therefore mainly unmeasured and unresearched – workforce.

Based on reviewing all of this information, the research team concluded that several forms of scenarios were possible with the ultimate aim of modelling the impact of net zero and biodiversity commitments, particularly those for forestry planting and peatland restoration (and acknowledging that there is considerable potential for land use trade-offs):

  • Technically oriented scenarios, following closely Scotland’s commitments in the update to the Climate Change Plan and Biodiversity Strategy; these could be single sector focused, or include multiple sectors, e.g. productive forestry vs natural capital driven land use priorities.
  • Broad narrative-based scenarios reflecting societal level drivers of change as for instance used in the Working Futures study.
  • Geographically defined scenarios to highlight regional level drivers and outcomes.

A13.4 Expert input

The team sought further advice from several individuals in different stakeholder organisations across the land-based sector to inform the approach. Undertaking additional qualitative data collection to inform the quantitative work in scenario-based modelling is an approach advocated by researchers involved in the Working Futures programme (see for example, Dunkerley et al. 2022):

  • There are potentially huge variations in the cost of peatland restoration (in particular) as the restoration work is dependent on such a wide range of factors, including altitude, previous/existing land use, access, etc. One of our interviewees commented on the potentially substantial input requirements:

“Easy lowland sites can be around £1,500 per hectare; more complex and more remote upland sites can be in the region of £5,000 per hectare. However, in the Peak District they are looking in the region of £25,000- £40,000 per hectare. The numbers and types of machines vary too, depending on access (i.e. some hill tracks and bridges can’t take 14 tonne diggers which may be most useful for most damming work) and helicopter requirements. If material, such as coir logs, stones for dams, mulch and liming are required, then the price varies hugely.”

  • Some large education and training providers can be slow to respond to market changes due to the time needed to recruit new staff and progress new courses through validation programmes. However, developing new short courses in areas where there is existing in-house expertise may be quicker (SRUC and NatureScot’s recently launched accredited peatland restoration course is a good example). Smaller, local training providers will also have flexibility to respond to changing needs in different locations from different groups (e.g. women seeking to enter the labour force), especially if they are able to deliver remotely.
  • Further work on the future labour market must be informed by those working in the sector, whether that be contractors, project consultants, etc. This was the case for Glaister’s (2019) work on the future employment requirements in the forestry sector for example. Their knowledge of ‘on the ground employment-related issues’ such as the extent to which people working in peatland restoration may switch to undertake woodland creation (or vice versa), or those working in other parts of the construction industry may switch to peatland restoration is crucial to ensuring that future modelling work truly reflects the situation on the ground. In terms of the latter switch, the short window in which peatland restoration is possible (for example in some locations only once snow cover is gone and before ground nesting birds arrive) means that this may be unlikely.
  • The need for more granular data relating specifically to skills requirements in particular sectors. One example is conservation-related activities where specific data is currently hard to find, but these activities are of increasing importance given the biodiversity and climate change crises. Underlying this again is the need to ensure that there is clarity about what is meant by conservation-related activities, i.e. a clearly defined set of SIC codes.
  • It is extremely difficult to anticipate the geographical impacts of future labour requirements as this depends on individual worker mobility (which may be reduced when the cost of fuel is high for example, making travel uneconomic) but also a range of other factors. The labour market in the south of Scotland, for example, will be affected by developments south of the border with England relating to forestry planting or peatland restoration targets, wage levels, etc.
  • Specific questions about the future of the labour market and the number of jobs in peatland restoration, woodland creation, tourism and hospitality etc. are tied up with wider debates about the future of Scotland’s land and landscapes, and indeed its rural communities. If the labour market continues to be ‘tight’ as Scotland recovers from the Covid-19 pandemic, there will be competition between sectors for workers, and prioritisation may need to occur.
  • Several interviewees emphasised the importance of place-based solutions co-created with communities that live locally and informed by local priorities and needs, and delivered locally. The latter may involve larger education and training providers shaping their provision to fit the requirements of their region/locality, and smaller training providers also making a substantial contribution. The current work being led by Scottish Rural Action to strengthen Scotland’s rural movement may help to provide a forum for further discussion on this[38].

Appendix 14: Our approach to the scenario-based modelling for peatland restoration and woodland creation

This Appendix sets out more detail about our proposed methodological approach to estimating future labour requirements in peatland restoration and woodland creation activities.

A14.1 Peatland restoration – overview of methodological approach

The research team effectively sought to perform an economic impact assessment of the Scottish Government’s target to restore 20,000ha peatlands per year in order to consider the impact on employment in upstream sectors. The team searched the literature for information on peatland restoration costs, seeking to understand unit costs of different inputs, including labour and machinery requirements, and how these may vary between sites.

From this we proposed to estimate the typical cost structure of peatland restoration work and apply this to estimate changes to final demand in upstream sectors (those supplying inputs, e.g. materials, machinery and consulting services) arising from the Scottish Government’s planned £25 million per year investment in peatland restoration. The resulting effects on employment in upstream sectors may then be estimated using the multipliers from the Scottish Government’s Supply and Use Tables (or the Scottish Government’s Input-Output (I-O) tables). We acknowledge that these I-O tables cannot provide full and accurate information on the local and/or regional non-market benefits (such as social and environmental impacts) of peatland restoration (or woodland creation) because the I-O analysis only includes information on monetary values.

A14.2 Peatland restoration – data on input costs

We searched the literature for information on peatland restoration costs, seeking to understand unit costs of inputs, labour and machinery requirements and how requirement for these may vary between sites.

Per ha restoration costs

Glenk et al. (2022; 2021; 2020) analyse peatland cost data from monitoring forms submitted to the Peatland Action Programme. This provides the most recent and comprehensive overview of per ha. restoration costs in the published literature. The authors report that to their knowledge no other comparable dataset exists.

Their most recent (2022) analysis reports median restoration costs to be £1,026 per ha and mean to be £1,712 per ha., n = 174 observations across all projects submitted 2016/17 to 2020/21, based on final reported costs. They further highlight variation in per ha. costs by restoration technique and initial site condition. As indicated in Figure A4 below the distribution of restoration costs is somewhat skewed. Due to this they consider that median is a more informative than mean, as mean estimate is distorted by a few large observations.

In a review funded by NERC, RESAS and the University of Leeds Climate Research Bursary, Okumah et al. (2019) provide an overview of per ha. peatland restoration costs within the published literature. While their review does not detail unit costs, they highlight additional (limited) data which indicates that per ha. costs vary significantly by materials required. (See Table A8 for the specific data from this work.)

In a review commissioned by the IUCN UK Peatland Programme’s Commission of Inquiry on Peatlands, Artz et al. (2019) provide an updated schedule of per ha. restoration costs within the published literature. They further report unit costs for a small number of materials and methods. (See Table A9 for the specific data from this work.)

Artz et al. (2018) Peatland restoration – a comparative analysis of the costs and merits of different restoration methods

 

In a review commissioned by CXC, Artz et al. (2018) review 70 publications and report per ha. restoration costs within the published literature.

They further present results from a survey administered to a representative sample of 30 case study sites (twenty three responses, eighteen included) from 150 peatland action projects completed until April 2017. From this they note challenges in obtaining data on unit costs and the cost structure of peatland restoration.

While they receive data from 18 sites, many of the surveys contained inconsistencies between total reported costs and cost breakdowns and they received invoiced costs for only 10 of the surveys.

“Only a very few survey returns specified the breakdown of the costs to capital expenditure (6), labour costs (10), operating costs such as fuel and materials (2), and unforeseen costs (2). This was because the grantees and Peatland Action officers generally did not have access to this level of information on the actual spend, it was the contractors that would have held this information, but we did not receive sufficient responses from this community. It was not possible to carry out in-depth analysis on these sparse data, and hence only some preliminary observations on labour costs can be included here.” pp.17

They report that ten surveys contained partial data on staff time and day rates. “A total of 241 paid staff days, ranging from 5 to 60 days between these ten projects, were required at an average cost of £220 per day. In addition, two of these projects specified a total of 82 days of unpaid workers at an estimated day rate of £100, although the cost estimate was only given for one of these projects.”

Overall, due to the relative lack of data they are unable to conclude whether labour is a significant component of total costs.

A14.3 Peatland restoration – Data challenges encountered

While the quality and availability of data on per ha peatland restoration costs is increasing, specific and accurate information on unit costs is sparse and we have been unable to find a reliable indication of the cost structure of peatland restoration and woodland creation work within the published literature.

Various important factors have been highlighted in the literature as contributing to substantial variations in peatland restoration (and woodland creation) costs. These include forest to bog conversion (Glenk et al. 2022), the restoration technique required (Glenk et al. 2022), remoteness and accessibility (Artz et al. 2018), degree of drainage/number of dams required on lowland peat (Grand Clement et al. 2015) and increases in material requirements relating to the degree of degradation (stakeholder interview).

While there is increasing understanding of these factors, the marginal influence of specific factors is not easily discernible from existing cost data which largely summarises per ha and does not control for variation in degradation or magnitude of work required when reporting per ha values for restoration techniques. We were unable to find information on how labour or machinery requirements may vary by site conditions.

Overall, we did not consider that we could achieve a reliable estimate for cost structure and accordingly we have not performed the preferred modelling approach.

However, based on our work, the research team offers recommendations for future work to tackle these data challenges, and indicative estimates of jobs in peatland restoration and woodland creation based on extrapolation of estimates from prior studies.

A14.4 Peatland restoration – Recommendations for future work

Approximately half of all peatland restoration projects in Scotland are supported by Peatland Action. The Peatland Action data, analysed by Glenk et al. (2022; 2021; 2020) and Artz et al. (2017) is the most comprehensive overview of restoration costs in Scotland. The research team believes that it would be worth considering how the collection of data on unit costs and cost structure of works could be enhanced, without raising the burden of data collection for those running and managing projects unnecessarily. The work by Glenk et al. (no date) provides a literature review and highlights wider considerations for the collection of peatland restoration data in future.

In addition to our suggestion of increasing data collection through funded projects, it is worth considering potential future primary research to generate additional data. Given the lack of data on unit costs in the published literature, an alternative approach to understanding future employment and skill requirements in peatland restoration (and woodland creation) may be to design a survey/qualitative study targeting peatland restoration (and woodland creation) consultants, contractors and training providers in order to better understand peatland restoration (and woodland creation) capital budgeting and workflow, as well as factors that may increase the cost/ difficulty of restoration work.

Should the aim of this work be to estimate workforce requirements at the national level, then in scoping such work it would be beneficial also to consider what distributional data exists at the national level that may inform understanding of distribution of sites in relation to factors that may increase cost/difficulty of restoration. Relevant factors may include those mentioned above that contribute to the substantial variations in cost estimates for different peatland restoration sites.

A14.5 Woodland creation – overview of methodological approach

Having first focused on peatland restoration, the research team then sought to perform an economic impact assessment of the Scottish Government’s 18,000ha per year afforestation target (from 2024/25), again in order to consider the impact on employment in upstream sectors. To inform this analysis we searched the literature for information on woodland creation costs, seeking to understand unit costs of inputs, e.g. labour and machinery requirements, and how these may vary between sites.

We were similarly unable to find a reliable indication of cost structure within the published literature, and so again the intended analysis could not be performed.

A14.6 Woodland creation – information on input costs

The costs of woodland creation depend on a number of factors, particularly depending on whether the site requires clearing, draining, weeding, and fertilising. Typically, tree-planting programmes have high upfront costs, as the cost of acquiring the land can be elevated. Using the information from the report by Vivid Economics (2020), Dicks et al (2020) reveal that the costs of woodland creation can be classified into capital costs, operational costs, and opportunity costs.

Capital costs usually refers to the one-off upfront cost of converting land from its previous use, which include the cost of finance incurred by borrowing to pay for initial investments, planting trees and building fences, and acquiring machinery (the Scottish Government, 2022).

Operational costs are the recurring costs associated with tree planting such as maintenance costs for fence repairs, pest control, fire protection, payment of wages, contracts fees and expenses for project monitoring (Dicks et al., 2020). While the opportunity costs associated with woodland creation often refer to foregone agricultural income, loss in open ground habitats and related reduction in recreational activities, cost of land acquisition and compensation payments for forgone income (Dicks et al., 2020). Table A10 summarises different types of costs related to the woodland creation activities.

  3. Work is currently underway involving Scottish Government RESAS staff and SRUC researchers to facilitate access to HMRC data for Strategic Research Programme work on the rural economy. This process will take time, but it is hoped that if it is possible to access this data, we will be able to get a much more detailed picture of the entire population of rural businesses.



  4. Professor Sally Shortall at Newcastle University, for example, has a number of publications and projects on this theme.



  5. This includes Skills Development Scotland’s SSA for Agriculture, forestry and fishing and for Food and Drink – Primary Food Production, the Agriculture Census, Science and Advice for Scottish Agriculture (SASA), the Industry Leadership Group on Food and Drink, work by researchers at SRUC and the James Hutton Institute (for example) on the sector (for example, through the Scottish Government’s Strategic Research Programme), and data gathering work by the National Farmers Union Scotland, Quality Meat Scotland, the Agriculture and Horticulture Development Board, the Scottish Agricultural Organisations Society, the Women in Agriculture movement and others.



  6. Work is currently going on at SRUC within the NISRIE project, which forms part of the Scottish Government’s Strategic Research Programme 2022-27, to explore the accuracy of this figure. Initial analysis of data from the Farm Structure Survey (the latest of which took place in 2016) suggests the real figure may be somewhat different and that a more nuanced approach is needed to calculating the workforce. The 67,400 total refers to ‘headcount’ which includes people who may only work on a very limited basis. It also does not include family labour. It is also difficult to define an FTE in agriculture when so many workers will work ‘overtime’.



  7. The Employment statistic within the Business Register and Employment Survey further includes working owners.



  8. The difference between Employment and Employees within the BRES data again highlights the significance of working owners within the agricultural workforce.



  9. These include Forest and Land Scotland and Forest Research (who produce Forest Statistics), the Confederation of Forest Industries (CONFOR), the Forest and Timber Technologies Industry Leadership Group, or private forestry companies and land agents that collect data on the price of timber, etc.

The definition of the forestry and timber processing sector in this study was “activity related to forestry, trees, woodland and primary timber processing (pulp mills, production of sawn wood, wood panels, fencing posts and woodfuel, including chips, briquettes, pellets, firewood and other woodfuel) in Scotland, and note that this includes forest management and primary timber processing, forestry civil engineering, haulage, agent, community groups with interests in woodlands, NGOs, local authorities with woodland activity, research and education, and those activities of the Forestry Commission and Forestry Commission Scotland, which are located in Scotland. this excludes secondary processing and paper production from imported pulp and most haulage from primary to secondary producers.”



  11. This estimate is based on data from the CJC Consulting (2015) report yet takes a wider industry definition and further includes employment in tourism linked directly to forestry. Total employment is estimated as direct employment plus jobs indirectly supported within the wider supply chain plus those induced through spending of wages.



  12. This figure is based on the CJC Consulting (2015) study and combines their values for the forestry and timber processing sector (19, 555) and forest related recreation and tourism (6, 312).

  14. These figures from NOMIS suggest that all of the 4,500 workforce in 2021 were working full-time but the data breakdown confirms 450 part-time employees. There may be an error in how this data is listed in the open access file, or this is due to rounding of the data, but further interrogation is needed to check these totals.



  15. Forthcoming work by Frontline Consultants, Westbrook and Ralph to quantify the GVA impact of the forestry sector in the UK and sub-nations may provide further insight on this trend.



  16. A handful of estimates for peatland employment effects have been produced in the context of wider modelling studies where peatland employment was not the main focus. These are detailed in Appendix 12. Estimates of the future peatland restoration workforce are discussed in section 8.1.3.

  18. In the preface to the report, the Committee highlights the following key messages:



    • while achieving net-zero targets will entail transformational change to the economy, the majority of workers will not see major impacts;

    • there is potential for net zero transitions to create more jobs than are lost; and

    • the transition could provide opportunities for job growth in areas of traditionally low employment, and support diversification of the workforce in net zero sectors.


    Across the UK economy as whole they estimate that “the transition could bring 135,000 to 725,000 net new jobs, including 8,000 to 75,000 job losses.”

  20. ‘The Skills Imperative to 2035’ programme of work notes a similar set of generic skills which will be in greater demand, including creativity, critical thinking, teamwork, problem solving and resilience.



  21. Responsibilities towards existing seasonal employment may also constrain workers ability to seek other employment. For instance, The Women in Farming Report found that “women juggle off- farm work around the needs of the farm” and would take holidays from off-farm work during lambing (Shortall et al., 2017). It also found that responsibility for feeding and housing (seasonal) migrant workers tended to fall upon women.



  22. For instance, the Chartered Institute of Personnel and Development (2022) reported that employers are reporting labour shortages as a dominant issue across all sectors, with 47% employers reporting hard to fill vacancies. Fraser of Allander (2022) similarly reported a high proportion of businesses experiencing recruitment difficulties and problems filling roles, while Skills Development Scotland (2022) note that labour shortages remain a dominant issue for businesses in Scotland.



  23. such as aquaculture and urban greenspaces which neither fit well beneath ‘land based’ or ‘rural’.



  24. They highlight that low levels of student enrolment in forestry courses, alongside declining provision of forestry courses, is leading to a critical skills shortage relative to the level of provision required to meet forestry sector targets. Following the closure of higher education courses at Edinburgh, Oxford, Aberdeen and Newton Rigg, much of the remaining higher education provision is in England (Bowditich et al, 2022).

  31. It is likely that word of mouth is important in terms of recruitment into many jobs in rural areas, including in the land-based sector. As such, employers may be more likely to mention job opportunities informally (e.g. at marts or at social events) or on social media and so they may not appear in official job vacancy statistics. There is also a bigger risk for small employers if they take on a new, unknown member of staff. It is also worth noting that it can be difficult for those individuals who find themselves outside these local networks for whatever reason (e.g. because they are new to the local area) to find work (for more information on informal networks in the rural labour market, see this paper published in 2003: Unemployment duration and employability in remote rural labour markets – ScienceDirect.

  36. Recognising that work closures due to snow place additional costs on contractors and that this may adversely affect the perception of industry security, Peatland ACTION have introduced snow day payments to encourage retention of machinery at site where work is disrupted by snow for short periods of time.

  37. Morgan (1999) outlines various constraints on planting date including tree species, type of seedstock, climatic zone and soil type, then goes on to suggest indicative planting dates by species and climatic zone. Overall, it is recommended that trees are planted into warm soils (>6°C) allowing four weeks of root growth before winter. Due to this planting during December and January is only recommended for a limited range of species in milder, sheltered areas. High elevation sites may be planted from mid- March onwards once soil temperatures have increased.

Different foods have different levels of greenhouse gas emissions. Therefore, dietary transitions can play a role in meeting net zero emission targets. The Climate Change Committee’s Scottish progress review in December 2022 included a call to change Scottish diets.

This report examines current evidence on dietary patterns and their associated emissions to establish a baseline understanding of the climate impact of food consumed in Scotland.

Summary findings

There is significant uncertainty around the magnitude of emissions associated with food consumed in Scotland. Data gaps contribute to uncertainty, particularly relating to estimates for children and regional variability in food consumption and associated emissions.

While cereals, vegetables and potatoes are important contributors to nutrient intake, meat and dairy are important contributors to both nutrient intake and greenhouse gas emissions in Scottish diets.

Further research into where foods consumed in Scotland are produced and processed, along with research into the nature of under-reporting in food consumption data would improve the accuracy of estimates. Two approaches are recommended:

  • Bottom up: starting with consumption data to enable estimation of emissions from specific food groups and by specific population subgroups.
  • Top down: adding up the emissions from sectors involved in the food system has the benefit of being more comprehensive. It can include emissions often missing in studies that start with consumption data, such as emissions from household and hospitality energy use, consumer transport and food waste disposal.

Together these approaches would provide a more complete picture of greenhouse gas emissions associated with food consumed in Scotland, and provide cross-validation.

Executive summary

The foods we eat in Scotland contribute to greenhouse gas (GHG) emissions. Different foods have different GHG emissions, and therefore dietary transitions can play a role in meeting net zero emission targets. The Climate Change Committee’s Scottish progress review in December 2022 included a call to change Scottish diets.

This report examines current evidence on dietary patterns and their associated emissions to establish a baseline understanding of the climate impact of food consumed in Scotland.

What are food systems?

The draft National Good Food Nation Plan defines foods systems in line with the United Nations’ definition as “all the elements (environment, people, inputs, processes, infrastructures, institutions, etc.) and activities involved in the production, processing, distribution, preparation and consumption” of food.

Some of the food produced or processed in Scotland is exported to the rest of the UK or overseas. While this is important for Scotland’s territorial emissions, exported food is not within the remit of this report.

How does the food we eat contribute to greenhouse gas emissions?

Activities at each stage of the food system contribute to GHG emissions. Examples include from the production of synthetic fertilisers; from energy use during processing, packaging, and cold storage; and from the disposal of food and food packaging waste, though globally 70% of food system-related emissions arise from food production.

The most comprehensive analysis of GHG emissions associated with food consumed in the UK, by WRAP, found the following breakdown:

  • 29% from UK agriculture and fishing
  • 26% from imported food
  • 10% from land use change from imported food and animal feed
  • 6% from household energy use to prepare food
  • 5% from energy use to manufacture food in the UK
  • 4% from energy use by hospitality and food service
  • 4% from food packaging
  • 4% from transport within the UK

Thus, improvements in the efficiency of food production are especially critical for climate change mitigation.

Food consumption in Scotland

Current consumption patterns, particularly of meat and dairy, are important for understanding the GHG emissions associated with food consumption in Scotland and identifying strategies to improve the sustainability of Scottish diets. Our analysis and review of food consumption in Scotland revealed that:

  • The four most important food groups contributing to nutrient intake in Scotland are:
  • Cereal products
  • Milk products
  • Meat
  • Vegetables and potatoes
  • Meat is frequently consumed in Scotland by most people. Meat eaten is primarily poultry (37% of total grams of meat consumed by adults 16+ years), pork (34%) and beef (25%). Lamb (3%) makes only a small contribution.
  • Milk products are consumed even more frequently than meat in Scotland and by nearly all people (86% of adults consume some meat and 99% consume some dairy).
  • Milk products are especially important for children aged 1.5-3 years, constituting nearly one-quarter of energy intake.
  • One-third of adults and one-fifth of children consume oily fish at least once a week.
  • Only about one-fifth of adults and children consume 5 or more portions of fruits and vegetables per day. Tomatoes and potatoes are the most frequently reported vegetables, whereas bananas are the most frequently reported fruits.
  • In recent years, fewer adults and children report consuming sugar-containing soft drinks and biscuits on a daily basis.
  • Generally, those living in the most deprived areas of Scotland have less healthy diets than those living in the least deprived areas. Specifically, they have lower intakes of fruits and vegetables, brown/wholemeal bread and fish; and higher intakes of sugar-containing soft drinks, processed potatoes and takeaway foods.

Greenhouse gas emissions from food consumed in Scotland

  • We found very limited evidence for the GHG emissions associated with food consumption in Scotland. Given that food consumption patterns are broadly similar in Scotland and the UK, we relied on the wider evidence base on emissions associated with food consumption in the UK, assuming emissions are proportional to population.
  • There is substantial uncertainty in the magnitude of emissions associated with food consumption in Scotland, with estimates ranging 4.9 to 17.1 MtCO2e.
  • Several factors likely contribute to this variability:
  • Some models include land use and land use change whereas others do not.
  • Only one model included emissions from packaging, hospitality and food service, household energy use, consumer transport and deliveries and food waste management, which together accounted for approximately 18% of GHG emissions associated with food consumed in the UK.
  • Two of the models relied on self-reported dietary intake, which is known to be under-reported.
  • Each model handled emissions from imported food differently, and all models had significant uncertainty in country-of-origin data for imported foods.
  • There is consistency in several results:
  • Red and processed meat (including processed pork and other processed meat) is consistently the largest food group contributing to emissions.
  • GHG emissions associated with food consumption have declined over the past 30 years due to several factors, including reductions in consumption of red meat and decarbonisation of electricity.

Conclusions

While cereals, vegetables and potatoes are important contributors to nutrient intake, meat and dairy are important contributors to both nutrient intake and GHG emissions in Scottish diets.

There is significant uncertainty around the magnitude of emissions associated with food consumed in Scotland. Data gaps contribute to uncertainty of estimates for children and of regional variability in food consumption and associated emissions.

While recent data on adult food consumption and food life cycle assessment (LCA) databases are available, and together could help fill these gaps, further research into the following would improve the accuracy of such estimates:

  • Information on where foods consumed in Scotland are produced and processed
  • The nature of under-reporting in food consumption data in Scotland, particularly for specific foods (e.g., meat and dairy)

Taking a ‘bottom up’ approach (starting with consumption data) is recommended to enable estimation of emissions from specific food groups, e.g., meat versus fruits and vegetables, and by specific population subgroups, e.g., men versus women, adults versus children, and by neighbourhood deprivation.

At the same time, a ‘top down’ approach (adding up the emissions from sectors involved in the food system) has the benefit of being more comprehensive. However, it is challenging to estimate emissions associated with specific foods or for population subgroups using this approach.

A ‘top down’ approach can include emissions often missing in ‘bottom up’ studies such as emissions from household and hospitality energy use, consumer transport and food waste disposal. Together, both approaches would provide a more complete picture of GHG emissions associated with food consumed in Scotland, and provide cross-validation.

Background

What are food systems?

The draft National Good Food Nation Plan[5] defines foodsystems in line with the United Nations’ definition as “all the elements (environment, people, inputs, processes, infrastructures, institutions, etc.) and activities involved in the production, processing, distribution, preparation and consumption” of food (Westhoek et al., 2016) (Figure 1).

A figure depicting the stages of the food system in order: production and land use; processing; distribution; retail; preparation; consumption; disposal.

Figure 1: Stages of the food system.

Because some of the food we eat in Scotland is produced and processed in the rest of the UK or overseas, our food system encompasses not only farms, fisheries, aquaculture, processors and distributors in Scotland, but also in many other parts of the world.

Some of the food produced or processed in Scotland is exported to the rest of the UK or overseas. While this is important for Scotland’s territorial emissions, exported food are not considered for consumption metrics such as the carbon footprint of Scottish diets, which is the focus of this report.

How does the food we eat contribute to greenhouse gas emissions?

Activities at each stage of the food system (Figure 1) contribute to greenhouse gas (GHG) emissions. For example, GHG emissions arise from:

  • deforestation to expand agricultural area to produce food or animal feed,
  • the production of synthetic fertilisers,
  • greenhouse gas emissions from production, such as methane emissions from ruminants and nitrous oxide emissions from fertiliser use,
  • diesel used by fishing vessels,
  • energy use for processing and packaging commodities like wheat, sugarcane, and oilseeds into processed foods,
  • diesel used to distribute food to retailers,
  • energy use for cold storage during transport and in retail settings,
  • energy use of appliances for preparing food at home,
  • and disposing of food and food packaging waste.

The use of land for food production contributes to GHG emissions (Intergovernmental Panel on Climate Change, 2019). The quantity of carbon stored in soils and vegetation varies dramatically with land use change. Forests and peatlands are excellent at storing carbon, so when they are converted to pasture for livestock or cropland, the carbon stored is released to the atmosphere. If burning is used to convert the forests or peatlands, these emissions can occur rapidly. However, even when the land use change occurs through other means, e.g., draining of peatlands, the carbon is emitted as the vegetation and organic matter in the soil decays, either as carbon dioxide or methane – both GHGs. Additionally, when fertiliser is applied to pastures or crops, microbes in the soil break it down in a process that produces nitrous oxide, another GHG.

The most comprehensive analysis of GHG emissions associated with food consumed in the UK (Forbes, 2022) found that

  • 29% of emissions were from UK agriculture and fishing,
  • 26% from imported food,
  • 10% from land use change from imported food and animal feed,
  • 6% from household energy use to prepare food,
  • 5% from energy use to manufacture food in the UK, and
  • 4% each from
  • energy use by hospitality and food service,
  • food packaging, and
  • transport within the UK.

Other stages of the food system contributed <4% each to GHG emissions, including energy use by food retailers, consumer transport, consumer deliveries of groceries and takeaway, refrigerants, imported animal feed, fertiliser manufacture and disposal of food waste.

Though improvements in the efficiency of food production are critical for climate change mitigation, their ability to reduce GHG emissions has limits (Stewart et al., 2023). This is because some foods have higher impacts regardless of how they are produced. The emissions from even the lowest-impact beef exceed the average emissions from milk, which in turn exceeds the average emissions from eggs and plant-based proteins (e.g., tofu, groundnuts, pulses, peas and nuts) (Poore and Nemecek, 2018).

There are two major reasons beef production results in more emissions than other foods. First, cows emit methane, a potent GHG, over the course of their lifetime. This methane production contributes to the emissions associated with beef consumption. Although options exist to reduce methane emissions from cows, all ruminants – including cows and sheep – produce methane as part of their digestion. Second, it takes about 9.5kg of feed to produce 1kg of beef.[6] The emissions associated with beef consumption include the emissions from producing feed, whether that be fertilised pasture, soya or some other feed.

The wide range of emissions from different foods means that dietary transitions can play a major role in achieving net zero by reducing consumption of high-emissions foods in favour of low-emissions ones.

Aims

The foods we eat in Scotland contribute to GHG emissions. Different foods have different GHG emissions, therefore dietary transitions can play a role in achieving net zero. Recognising this, the Climate Change Committee recommended in their December 2022 report a target of a 20% reduction in all meat and dairy by 2030, increasing to a 35% reduction in all meat by 2050. In the Scottish Government’s response (June 2023), the Climate Change Committee’s recommendation was partially accepted. Several recent policies will support equitable, sustainable dietary transitions. Foremost among these is the Good Food Nation (Scotland) Act (2022). The Act requires that Scottish Ministers and relevant authorities, in preparing Good Food Nation plans, have regard to the role of sustainable food systems in contributing to climate change mitigation.

The objectives of this report were to describe current and historical food consumption patterns in Scotland, and the implications of these consumption patterns for GHG emissions. To meet these objectives, we conducted a rapid evidence assessment and secondary analyses of publicly available data from the UK Data Archive (see Appendix A for methodology). We then held a workshop with the authors of four UK models that estimated the GHG emissions associated with food consumption to better understand why their models resulted in different estimates of emissions (see Appendix B for a summary of that workshop).

The three aims were to:

  • Describe food consumption patterns of people living in Scotland.
  • Compare patterns of consumption by sex, age group, Scottish Index of Multiple Deprivation (SIMD) and health board.
  • Quantify the contribution of food groups to intake of essential nutrients, overall and by population subgroup.
  • Determine where the food consumed in Scotland is produced.
  • Summarise how a typical ‘Scottish diet’ has changed over the past 50 years.
  • Describe the GHG emissions associated with food consumed in Scotland.
  • Qualitatively estimate how changes in food consumption patterns over the past 50 years have affected GHG emissions.
  • Compare GHG emissions associated with food consumption by population subgroups.

Before describing current and historical food consumption patterns in Scotland, it is important to understand where the underlying data come from (Table 1). The focus of diet monitoring in Scotland over the past two decades has been the Scottish Dietary Goals (SDGs, see Appendix B

Summary of workshop on four published models to estimate greenhouse gas emissions associated with food consumed in the UK

The University of Edinburgh convened a one-hour online workshop to discuss the different approaches to modelling emissions associated with food consumed in the UK. The lead authors of the four published models identified in our review attended the workshop. The discussion was in two parts: (1) the lead authors presented an overview of their modelling approach (Table 7), and then (2) the group discussed potential drivers of differences across models in estimated greenhouse gas emissions associated with food consumed in the UK (Table 8).

Model

Summary of approach

WRAP

Builds the estimates using sector-specific information from published UK inventories of emissions, rather than LCAs of specific foods consumed. Current area of focus is improving the estimates of imported food emissions, with future intentions to look at the potential impact of on-farm mitigation in the UK.

Several strengths of this approach, including:

  • Ability to capture hospitality, cooking at home, and food waste management [which are typically not reflected in cradle-to-retail gate LCAs]

  • Ability to update estimates every year to account for shorter-term changes, e.g., in the electricity grid, whereas LCAs are often ‘static’ to a particular year
  • LCAs are used for imported food and are, in some cases, specific to country of import – where there is reason to believe there would be a substantial impact, such as beef and lamb. Further work for this model will focus on improving estimates for traded food and the associated emissions, looking at creating more specificity for products coming from certain locations, and integrating international transport.

    However, it is not without limitations:

  • Cannot look at population subgroups

  • Harder to look at food groups; could be done using other datasets not currently included in their model but this is outside their current scope of work

  • Land use change is currently focused on specific commodities such as palm oil and soya; this could be improved
  • Data sources:
  • Governmental datasets such as UK inventories for agriculture and energy consumption by sector (manufacturing, food, retail, etc.)

  • Other data filled in, e.g., for household deliveries, hospitality, and refrigerant specific emissions

  • UK trade data linked to LCAs for imported foods
  • Stewart

    This model matches food consumption data to LCAs to estimate emissions. FAO data on food supply, production, imports, exports, seed and feed, were combined with Poore and Nemechek (2018) LCA data.

    Several strengths of this approach, including:

  • LCAs were disaggregated by continent and updated over time to reflect variability between continents and over time in emission intensities for commodities

  • Able to look at food group level data

  • Able to quantify changes in emissions from changes in consumption versus production efficiency versus trade
  • However, a limitation is that it does not include emissions from hospitality, cooking at home, consumer transport and deliveries, etc.Data sources:
  • FAO Food Balance Sheets

  • FAO emission intensities

  • Poore and Nemechek (2018) LCA data
  • Bates

    This model uses a database of emissions linked to NDNS food consumption data, originally developed for the University of Newcastle’s Intake24 dietary recall tool in order to provide feedback to survey participants on the environmental impact of their diets.

    The model strengths are:

  • GHGs were mapped from the largest number of unique foods and beverages than any previous UK study at the time

  • GHGs (CO2e as g/100g) were matched to the majority of individual foods in the NDNS database

  • Able to look at consumption by food groups and by population subgroups.
  • Data sources:
  • Published studies and company websites for LCA data

  • NDNS for food consumption data
  • CREDS

    Primarily purpose was to explore the potential of demand-side mitigation. The model explores three consumer-facing strategies: shifting to plant-based diets, following UK dietary recommendations, and reducing food waste. NDNS data were used for consumption levels by product, whilst the Family Food Survey was used for the calorific intake estimates. The correction for under-reporting was applied on a calorific basis. The representation of diets was based on 17 dietary profiles outlined in the academic literature.

    There are 69 food product categories covered by the model, using the Classification of Individual Consumption by Purpose (COICOP) classification system. UK MRIO model captures all process-based emissions and factors per food category expressed as emissions per £ spent. Whilst there are uncertainties in most input-output based modelling approaches, the UKMRIO model does incorporate import data from 15 world regions (based on data from 50 countries). This also reflects differences in agricultural production techniques (and consequently emissions factors) from each region. This model does not capture emissions associated with cooking or waste management, land use, or agricultural efficiencies, but subsequent iterations of UK MRIO do take into account land use change.

    Data sources:
    • NDNS, Family Food survey and literature reviews to describe example diets

    • UK MRIO model

    Aspect of model

    Summary of differences

    Land use change emissions
    WRAP and Stewart are the only models that include emissions from land use change
    Packaging, hospitality sector, and post-retail emissions
    WRAP is the only model that includes emissions from packaging, hospitality sector, and post-retail (e.g., home food preparation, consumer transport and deliveries, food waste management)
    Under-reporting of self-reported food consumption
    • Tendency to under-report in food diaries used in Bates and CREDS

    • CREDS did make a simple adjustment for under-reporting in their model

    Handling of imported foods

    • Concerns regarding the accuracy of the FAO trade database used in Stewart model

    • Uncertainty on country of origin data and farming systems (thus associated emissions) for imported foods – applies to all models

    • WRAP did some analysis around tracing country of origin and found that even when tracing a food product, if it does not come from our first trade partner, the second and third are often the same. For example, The Netherlands is our fourth-largest trade partner for palm oil, but they mostly import from the same top two trade partners as the UK (Indonesia and Malaysia). There were some anomalies, but for most, the import chain did not appear to make much of a difference

    • Stewart did a sensitivity analysis accounting for continent and found it varied by food group. For example, with beef, accounting for continent increased emissions by 25% (i.e., imported meat has higher emissions on average than UK produced beef), but with mutton, it decreased by 28% (i.e., imported mutton has lower emissions on average than UK produced mutton)
    Table 8: Summary of potential sources of variability between models used to estimate the greenhouse gas emissions associated with food consumed in the UK.

    Appendix C for a list of the SDGs), which were first set in 1996 (formerly known as Scottish Dietary Targets).

    As such, the Scottish Health Survey (SHeS) has collected data in adults and children on the frequency of consuming some foods such as fruits and vegetables since 1995, and on most foods relevant to the SDGs every 2 years since 2008. However, in order to estimate the GHG emissions associated with food consumption, you must know not only what foods are consumed but how much of each food is consumed. In 2018 and 2021, comprehensive food consumption data – i.e., what and how much – were also collected from adults 16+ years old in SHeS using a method known as a 24-hour dietary recall. This method involves asking the respondent to list all the foods and drinks they had on the previous day, and the amount they had.

    Self-reported food consumption is under-reported in the UK. A comparison study among adults in the UK of the 24-hour dietary recall method used in SHeS to a direct physiological measure of energy intake that is considered the ‘gold standard’ found that the recalls under-estimated energy intake by 25% (Foster et al., 2019). We do not know to what extent specific foods (e.g., meat and dairy) are under-reported. It is therefore difficult to estimate the impact of this under-reporting on GHG emissions.

    The second major source of food consumption information in Scotland is the Living Costs and Food Survey (LCFS). LCFS collects information on household food purchases and methods have been developed to estimate individual consumption from these data in Scotland (Wrieden et al., 2013; Barton, 2021). We did not identify any validation of LCFS data against measures of dietary intake, and therefore cannot comment on the extent of misreporting in LCFS estimates.

    Table 1: Major sources of food consumption information in Scotland.

    It is not possible to directly compare published estimates from SHeS and LCFS due to differences in the classification of foods. For example, SHeS groups vegetables and potatoes together and fruits separately, whereas LCFS groups fruits and vegetables together and potatoes separately.

    Moreover, neither SHeS nor LCFS have sufficient samples in a given year to estimate food consumption patterns at the level of the local authority. Even at the level of health boards, NHS Borders, NHS Dumfries and Galloway, NHS Orkney, NHS Shetland and NHS Western Isles have samples of under 100 adults in SHeS 2021.

    In the following section, all results for adults are from SHeS 2021, the latest representative data, unless otherwise specified. The latest representative data for children living in Scotland are from 2010 (Masson, 2012). A representative survey of diets in children and young people living in Scotland was launched in January 2024 and results should become available in the spring 2024.[7] As dietary patterns are broadly similar between Scotland and the wider UK (Figure 2), for children we rely on UK-wide data collected as part of the National Diet and Nutrition Survey (NDNS). The latest published estimates for children from NDNS are combined estimates for 2016/17, 2017/18 and 2018/19 (herein 2016/19). By combining three cycles, a sample size of 306 children 1.5-3 years, 725 children 4-10 years and 683 children 11-18 years is achieved. NDNS does not publish how many of the children in each age category are from Scotland versus elsewhere in the UK, although the overall survey is broadly representative of the UK, with around 10% of the sample from Scotland each year.

    Current patterns of food consumption in Scotland

    To explore current patterns of food consumption, we explored which food groups contribute the most to energy intake (Figure 2).[8]

    A stacked bar graph depicting the contribution of different food groups to energy intake in Scotland (Scottish Health Survey, 2021) and the UK (National Nutrition and Diet Survey, 2016/19) by age group.

    Figure 2: Food groups contributing to energy intake in Scotland (SHeS 2021, 16+ years) and the UK (NDNS 2016/19, 1.5-64 years)

    ‘Cereal products’ includes pasta, rice, pizza, bread, breakfast cereals, biscuits, buns, cakes, pastries, fruit pies, and cereal based and sponge puddings. ‘Meat’ includes bacon and ham; beef, veal and dishes; lamb and dishes; pork and dishes; coated chicken and turkey; chicken and turkey dishes; liver, products and dishes; burgers and kebabs; sausages; meat pies and pastries; and other meat and meat products. ‘Confectionary’ includes sugars and preserves. ‘Drinks’ are non-alcoholic. ‘Other’ is food groups contributing <4% of energy for all population subgroups, including eggs and egg dishes, nuts and seeds, and fish and fish dishes. For details, see: https://assets.publishing.service.gov.uk/media/5a7c7da5ed915d6969f453de/dh_128551.pdf

    Meat and meat products

    Meat and meat products contributed 14% of energy intake in adults; 18% in young people 11-18 years old; and 11-13% in children 1.5-10 years old.

    Meat is frequently consumed in Scotland. In 2021, 86% of adults consumed meat on at least one of up to two days of dietary recalls, with 69% consuming meat on both days (Stewart et al., 2023). Men consumed more meat than women. This difference begins early in life; SHeS 2018 for children 2-15 years found that boys were more likely than girls to eat meat products (such as sausages, meat pies, bridies, corned beef or burgers) at least twice a week (41% of boys versus 36% of girls) (Scottish Government, 2018). Processed meat intake was highest among young adults 16-24 years old and white meat intake was highest among adults aged 25-34 years. There was no difference in total meat intake by SIMD. However, adults in the least deprived SIMD were less likely to be a high consumer of red and red processed meat (31%) than those in the most deprived SIMD (44%).

    Most meat eaten was poultry (37% of total grams of meat consumed by adults 16+ years), pork (34%) and beef (25%), with very small contributions from lamb (3%) and game (1%). These contributions did not differ with sex or SIMD, except for game which had a higher contribution among those in the least deprived SIMD. The contribution of lamb to meat intake was higher among older age groups. The most frequently reported ways in which adults in Scotland eat meat are chicken breast (fried, roasted or grilled), ham sandwiches, spaghetti Bolognese, chili con carne, beef lasagne, chicken curry, chicken casserole/stew and roast beef.

    With regards to the SDG for red and red processed meat, nearly three quarters of adults (72%) consumed no more than 70 grams of red and red processed meat per day (Scottish Government, 2022). Women were much more likely to meet this Goal than men (79% versus 64%, respectively). Adults 65+ years old were most likely to meet this Goal (76-77%) and those aged 35-44 years were least likely (66%).

    Milk products

    Milk products contributed 11% of energy intake in adults; 24% in children 1.5-3 years; and 10-14% in children and young people 4-18 years.

    Nearly all adults (95%) in Scotland consumed milk products on at least one of up to two days of dietary recalls, 88% consumed milk products on both days (Stewart et al., 2023). Among consumers, mean daily consumption of milk products was 241g, comprised of 180g milk, 27g yoghurt, 23g cheese and smaller quantities of cream and dairy desserts (7g) and butter (4g). There was no difference in milk product consumption by sex or age group among adults. Adults living in the least deprived areas of Scotland were the highest consumers of cheese, while adults in SIMD 4 (second-least deprived areas) were the highest yoghurt consumers.

    Most milk products came from milk (62%), followed by cheese (19%) and yoghurt (10%) with smaller contributions from cream and dairy desserts and butter (both 4%). Half of consumers only consumed low fat varieties of milk and yoghurt, while 23% consumed only full fat varieties.

    Fruits and vegetables

    Vegetables and potatoes contributed 9% of energy intake in adults and children and young people 4-18 years and 7% in children 1.5-3 years. The most frequently consumed vegetables[9] were fresh tomatoes, side salad (including lettuce, tomato and cucumber) and oven chips (4% of adults report consuming each of them); cherry tomatoes, carrots, new potatoes, frozen peas, boiled broccoli and baked beans (each 3% of adults); and mashed potato, cucumber, potatoes, chips, lettuce and baked potato (each 2% of adults). The most frequently reported fruits consumed were bananas (25% of adults report consuming them), apples (13% of adults), blueberries and tangerines/ mandarins/ clementines/ satsumas (both 6% of adults), strawberries, oranges and red grapes (each 5% of adults), raspberries (3% of adults), and pears, avocados, olives, fresh fruit salad and white grapes (each 2% of adults).

    With regards to the SDG for fruits and vegetables, only one-fifth of adults and children in Scotland consumed 5 or more portions of fruits and vegetables per day (Scottish Government, 2022). Adults 65-74 years old were most likely to consume their five-a-day (28% of men and 29% of women), whereas young adults 16-24 years old were least likely (9% of men and 17% of women). There were no significant variations in fruits and vegetable intake by age or sex among children.

    Discretionary foods

    Together, all discretionary foods and drinks account for 15% of energy intake in adults 16+ years with sweet biscuits being the largest contributor within the category (Food Standards Scotland, 2023). Additional foods that may also be high in fat, sugar or salt such as breakfast cereals; roast potatoes, chips and similar roasted potato products; pizza; yoghurts, fromage frais and dairy desserts; and ready meals together account for an additional 13% of energy intake.

    • Young adults aged 16-34 years and adults living in the most deprived communities drank the most sugar-containing soft drinks.
    • Young adults aged 16-24 years ate the most roast potatoes, chips and similar roasted potato products; whereas adults aged 75+ years ate the most sweet biscuits, cakes, sweet pastries and puddings, ice cream and ice lollies, yoghurts, fromage frais and dairy desserts and breakfast cereals.
    • 16% of children 2-15 years (18% of boys and 15% of girls) consumed sugar-containing soft drinks at least once a day (falling from 35% in both boys and girls in 2016) (Scottish Government, 2018).
    • Consumption of biscuits at least once a day also fell, from 32% in 2016 to 28% (30% of boys and 27% of girls) in 2018 (Scottish Government, 2018).

    Other food groups

    Cereal products contribute to nearly one-third of energy intake in adults and children 1.5-3 years and 38% in children and young people 4-18 years. The most frequently consumed cereal products are toasted white bread (6% of adults report consuming it), toasted brown bread (5% of adults), white bread rolls and white basmati rice (both 3% of adults), digestive biscuits, toasted multiseed wholemeal bread, Weetabix/wheat biscuits, brown bread (not toasted), chocolate digestive biscuits, white bread (not toasted), porridge made with water, and pasta shapes (white/ tricolore) (each 2% of adults).

    Sandwiches contribute 7% of energy intake in adults. The most frequently consumed sandwiches are ham sandwiches (25% of adults report consuming them), cheese sandwiches (14%), cheese and ham sandwiches (8%), bacon sandwiches (4%), egg mayo sandwiches (4%), and tuna mayo sandwiches (3%).

    Fish only contributes 3% of energy intake in adults and 2% in children and young people 1.5-18 years. About one-third of adults (33% of women and 29% of men) and 19% of children eat oily fish, such as salmon, at least once a week (Scottish Government, 2018).

    Food groups contributing to nutrient intake in Scotland

    There are four major food groups that contribute to nutrient intake in Scotland:

    • Cereal products
    • Milk products
    • Meat products
    • Vegetables and potatoes

    There are some additional food groups contributing at least 10% to select other nutrients (Table 2). Non-alcoholic drinks including tea, coffee, juice and sugary drinks.

    While there are some differences in the relative magnitude of these contributors between men and women, adults and children, and by deprivation, for all population subgroups, these are the top contributors.[10]

    Where food we eat comes from

    Where food is produced is important for GHG emissions associated with food consumption not only because of transport’s contribution to emissions, but because the efficiency of production varies substantially between countries (Crippa et al., 2021). For example, the emissions associated with producing a litre of milk in the UK are, on average, 1.2 kg CO2e (AHDB, 2021) whereas the global aggregate estimate in the frequently used Poore and Nemecek database for a litre of liquid milk is 3.2 kg CO2e (Poore and Nemecek, 2018). Given that most liquid milk consumed in Scotland is likely produced in the UK, and that 44% of total dairy intake among adults in Scotland is liquid milk (Jaacks et al., 2024), use of the global aggregate estimates will over-estimate GHG emissions from liquid milk.

    A contrasting example is lamb. The carbon footprint of lamb produced in New Zealand and consumed in the UK is 19 kgCO2e per kg of lamb meat (Ledgard et al., 2011), compared with 25 kgCO2e per kg of lamb meat in the UK (AHDB, 2021). For the lamb produced in New Zealand and consumed in the UK, 80% of GHG emissions are from the farm, 3% from processing, 5% from all transportation stages (including domestic transport in New Zealand and the UK and ocean shipping) and 12% from retailer/consumer/waste stages (dominated by retail storage and home cooking[11]) (Ledgard et al., 2011). The reason for lower emissions from lamb produced in New Zealand could relate to the fact that New Zealand sheep farming systems are based on year-round grazing of permanent perennial grass and white clover pastures, and low application rates of fertiliser to pastures (Ledgard et al., 2011). Importantly, brought-in feeds are not used in these systems (Ledgard et al., 2011).

    Of relevance to Scotland, where the food and drink sector is dominated by small- and medium-sized enterprises (SMEs), a recent review found that there is a large amount of variation in techniques, ingredients and production scale, which influence the GHG emissions associated with the products produced. They concluded: “For this reason, widescale generalisations are likely to not lead to accurate conclusions on climate related impacts for this sector” (Sandison and Yeluripati, 2023).

    We identified only one study that explicitly discussed the origin of food in Scotland (Copus, Hopkins and Creaney, 2016). This was a survey completed by 97 SMEs in the food and drink sector. Given that there are more than 40,000 food businesses in Scotland, and the low response rate for this survey,[12] results should be interpreted with caution as they are unlikely to be generalisable to the entire food and drink sector. While there was substantial variability between SMEs, on average, they found that SMEs were relatively localised: 37% of all inputs came from within 1 hour’s travel time of the production site and 29% from elsewhere in Scotland. In terms of sales, 47% of outputs were sold within 1 hour’s travel time and 25% to customers elsewhere in Scotland; less than 10% was sold outside the UK. However, there was substantial variability by product type. While no more than 5% of sales of bakery products, dairy/cheese, fruits/vegetables, and meat products were sold ? outside Scotland, 26% of grains/cereals, 40% of alcoholic drinks and 44% of fish/seafood were sold outside Scotland. Data from a larger, more representative sample is needed to understand the wider food and drink sector in Scotland.

    An unpublished report, entitled, ‘Estimation and evaluation of the origins of food consumed in Scotland,’ was recently commissioned by Scottish Government (SAC Consulting, 2024). This report was the first exercise to estimate the origins of food in Scotland so comprehensively. Consumption surveys (Table 1) do not collect information on the country of origin of reported foods. Key findings were as follows:

    • There is an increasing trend towards processing of Scottish produce in England and, in some cases, in Northern Ireland
    • As a result, the export and reimport of products is commonplace
    • This complicates the attribution of products consumed in Scotland. For example, if milk was produced in Scotland and transported to England for the production of cheese, which was then sold and consumed in Scotland
    • This is true across food groups, including meat, dairy, seafood and cereals
    • Based on production statistics, we produce enough milk, beef and lamb to meet current consumption levels in Scotland
    • Chicken production is ‘virtually non-existent in Scotland’ and pork production is ‘very small relative to demand’
    • Thus, most chicken and pork consumed in Scotland comes from the rest of the UK or is imported
    • There is very limited capacity to meet demand for white fish and for fruits and vegetables out of season
    • Most fish consumed in Scotland is imported
    • Bread wheat is imported from the rest of the UK, Germany and Canada (among other countries)

    Based on the recent Scottish Government report (SAC Consulting, 2024), 2022 horticulture statistics from Defra for the whole UK (Defra, 2023)[13] and a report from the UKRI-funded BeanMeals project (Nicholson and Jones, 2023), we summarised where a majority of top-consumed foods in Scotland are likely produced (Table 3). Fruits and vegetables have the greatest uncertainty.

    Table shows food items within food groups consumed in Scotland, the rest of the UK and the rest of world.

    Table 3: Summary of likely main sources of top-consumed foods in Scotland (as image)

    How food consumption patterns have changed in Scotland in the past 50 years

    The oldest dietary intake data identified in the rapid evidence assessment with national coverage was from the Scottish Heart Health Study, which recruited a random sample of 10,359 women and men aged 40-59 years across 22 districts of Scotland in 1984-86. At the time, dietary intake monitoring was more focused on nutrients and a few select food groups rather than overall diet. Only 8% of women in the highest social-class group met the World Health Organisation target for fruits and vegetables, while men and those in the lowest social-class group were even less likely to meet the targets (Bolton-Smith, 1991). Additional differences in consumption by socio-economic group were evident at that time – those in the lowest social-class group had higher total energy intakes and a higher proportion of diet from bread and potatoes, but a lower proportion from red meat and puddings (Bolton-Smith, 1991). These disparities were reflected in nutrient intakes: those in the lowest social-class group had 20-25% lower nutrient density values for fibre, vitamins C and E, and beta-carotene compared to those in the highest social-class group (Bolton-Smith et al., 1991a).

    The Scottish Heart Health Study also assessed ‘special diets’ and found 0.4% of the sample self-reported following a ‘vegetarian’ diet and 1 participant self-reported being a ‘vegan’ (Bolton-Smith et al., 1991). More than two decades later, in the NDNS (2008/09 to 2018/19 combined), 2.1% of participants reported being ‘vegetarian’ and 0.2% ‘vegan’ (Stewart et al., 2021).

    To understand trends prior to 1984-86, one must rely on UK-wide trends reported as part of LCFS. Key trends covering the period of 1970 to 2000, shown as figures in Appendix , include (Defra, 2011):

    • Milk and milk products
    • Total liquid milk decreased, and full fat milk was largely replaced with skimmed milks (including semi-skimmed and fully skimmed milks)
    • Yoghurt[14] increased
    • Cheese remained relatively unchanged
    • Meat
    • Beef, lamb, bacon and ham, and sausages decreased
    • Poultry increased
    • Pork remained relatively unchanged
    • Fish and eggs
    • White fish, cooked fish (e.g., canned fish) and eggs decreased
    • Oily fish and shellfish increased slightly
    • Fruits and vegetables
    • Potatoes and, to a lesser extent, fresh green vegetables decreased
    • Other fresh vegetables, frozen vegetables, bananas and fruit juice increased
    • Apples and pears, citrus and canned vegetables remained relatively unchanged
    • Grains
    • Flour, and, to a lesser extent, bread and biscuits decreased
    • Cakes and pastries decreased in the 1970s and have remained relatively constant since then
    • Breakfast cereal increased

    Scotland-specific trend analyses of LCFS data from 2001/03 to 2015/18 are available and provide information about more recent trends, namely:

    • Disparities in food consumption by SIMD did not improve from 2001/03 to 2007/09 (Barton et al., 2015)
    • Those living in the most deprived quintile have lower intakes of fruits and vegetables, brown/wholemeal bread, breakfast cereals, oily fish and white fish than those in the least deprived quintile
    • Those living in the most deprived quintile have higher intakes of sugar-containing soft drinks, other red meat products (includes the meat portion of meat pies, sausages, corned beef, burgers and pate), whole milk, processed potatoes and takeaway foods than those in the least deprived quintile
    • Some trends observed in earlier years have continued whereas others have not, namely, from 2001/03 to 2015/18 (Wrieden et al., 2013; Barton, 2021),
    • Fruits and vegetables and oily fish did not change
    • Red and processed meat decreased; the decrease has been much larger for women than men
    • Total bread decreased, driven by a decrease in white bread
    • Total milk decreased, driven by a decrease in full fat milk
    • Sugar-containing soft drinks decreased and sugar-free soft drinks increased
    • White fish and fresh potatoes decreased
    • Nuts increased
    • Cakes, biscuits, confectionery, processed potatoes and savoury snacks remained relatively constant

    One previous analysis used Kantar World Panel data to evaluate food energy purchases in 2007 as compared to 2012, hypothesising that these would be lower as a result of inflation-adjusted food prices being 12% higher in 2012 than in 2007[15] whilst median equivalised disposable income had decreased over the same time period (Whybrow, Horgan and Macdiarmid, 2017). They found that food energy purchases did indeed decrease, from 8.6 to 8.2 MJ per adult equivalent per day. At the same time, however, food waste decreased, and so the net food energy consumed did not change significantly: 7.3 vs. 7.2 MJ per adult equivalent per day (Whybrow, Horgan and Macdiarmid, 2017). Changes in food groups over this time period were not reported.

    GHG emissions associated with food consumption in Scotland

    The literature

    We identified only two abstracts[16] that estimated the GHG emissions associated with food consumption in Scotland. Both abstracts used purchase data from 2,844 households in the Kantar Worldpanel linked to emissions data from the Barilla Center for Food & Nutrition.

    The first abstract found that GHG emissions associated with food consumed in Scotland decreased from 2007 to 2012 by approximately 10%, with no differences by SIMD: for example, in SIMD 1 (most deprived), from 3.4 to 3.0 kgCO2e per adult equivalent per day (Whybrow and Macdiarmid, 2018). This was in part due to a reduction in purchases of red and processed meat. For comparison, an analysis of NDNS data (2008/9-2013/14) found that the diets of adult men and women, respectively, had average GHG emissions of 4.27 and 3.36 kgCO2e per day (Bates, Chambers and Craig, 2019) (see Appendix E for details regarding the LCA database used). Children had significantly lower diet-associated GHG emissions: 3.15 and 2.77 kgCO2e per day for boys and girls, respectively (Bates, Chambers and Craig, 2019). Applying these NDNS food consumption emission intensities to the 2022 Scottish Census data,[17] the GHG emissions associated with food consumption in Scotland would be estimated at 7.2 MtCO2e per year.

    The second abstract examined the relative quality of diet – as defined by adherence to the Scotland Dietary Goals – and compared it to dietary GHG emissions. When looking at how the interaction of diet quality and dietary GHG emissions was associated with cost, they found that the highest quality diets[18] with the lowest GHG emissions were 50% more expensive than the lowest quality diets with the highest GHG emissions (61 versus 40 p/MJ respectively) (Whybrow, Horgan and Macdiarmid, 2018). They also found that the highest quality diets were not necessarily lower in GHG emissions.

    Modelling sources

    Given this major gap in the literature of recent Scotland-specific studies on GHG emissions associated with food consumption, and given evidence that the foods consumed in Scotland are largely similar to those in the UK, we pivoted to three models of GHG emissions associated with food consumed in the UK and one global model that published UK-specific estimates (see Appendix B and Appendix E for details of each model). To convert UK-wide estimates to Scotland, we made the assumption that emissions are proportional to population (e.g., that Scotland is responsible for 8.2% of UK emissions).

    Two broad approaches have been used to estimate emissions associated with food consumed in the UK (Table 4). ‘Bottom up’ approaches link food consumption data to life cycle assessment data to calculate emissions. ‘Top down’ approaches sum emissions from the food and drink sector, subtracting emissions associated with exports and adding emissions associated with imports.

    Limitations
    Models

    ‘Bottom up’

    Linking consumption data (food availability, food purchases or dietary intake) to food life cycle assessments (LCAs) and calculating per capita GHG emissions

    • Consumption may be misreported
    • Uncertainty in origin of food reported and lack of specificity of LCAs limits accuracy
    • Issues over system boundaries, for example, LCAs typically end at retail and therefore do not include emissions from household and hospitality energy use, consumer transport or waste disposal
    • LCAs can become out-dated and may not accurately reflect improvements in production efficiency

    Stewart model

    CREDS1 model

    Bates model

    ‘Top-down’

    Summing GHG emissions from sectors involved in food supply chain, subtracting exports and adding imports

    • Significant uncertainty and variability in emissions associated with imported food
    • Issues over system boundaries, for example, whether or not land use emissions (e.g., from agricultural soils) or land use change emissions are in scope

    Variations in the modelling

    The GHG emissions associated with food consumed in Scotland vary widely (Figure 3), with estimates ranging from 4.9 to 17.1 MtCO2e.

    A bar graph depicting different estimates of the greenhouse gas emissions in Scotland identified in the literature. Estimates range from 4.9 to 17.1 Mt carbon dioxide equivalents.

    Figure 3: Greenhouse gas emissions associated with food consumed in Scotland.

    Values are from UK-wide models, extrapolated to Scotland by assuming emissions are proportional to population (e.g., Scotland is responsible for 8.2% of UK emissions).

    Several factors likely contribute to this variability:

    • Some models include land use and land use change[19] (Stewart and WRAP) whereas others do not (Bates and CREDS)
    • The WRAP model estimated that 10% of GHG emissions associated with food consumed in the UK come from land use change for imported food and animal feed; thus, this could partly explain why the Stewart and WRAP models resulted in higher GHG emissions than the Bates and CREDS models
    • Only the WRAP model included emissions from packaging, hospitality and food service, household energy use, consumer transport and deliveries and food waste management, which together accounted for ~18% of GHG emissions associated with food consumed in the UK
    • Two of the models relied on self-reported dietary intake (Bates and CREDS) which is known to be under-reported (see Section 7.1)
    • This may partly explain why the Bates and CREDS models had lower estimates of GHG emissions than the Stewart and WRAP models
    • Of note, the Stewart model used FAO Food Balance Sheets and the WRAP model used a top-down approach that did not rely directly on estimates of food consumption
    • Each model handled emissions from imported food differently
    • Some models matched specific LCA data to food groups based on trade information, either from FAO (Stewart) or UK Government (WRAP and CREDS)
    • All models had significant uncertainty in country-of-origin data and farming systems (thus associated emissions) for imported foods

    The results of each model are discussed in greater detail below.

    Results of the WRAP model

    Sourced from Forbes, Fisher and Parry, 2021; Forbes, 2022)

    • Food consumed in the UK contributed 154.8 MtCO2e in 2020
    • Applying the assumption that emissions are proportional to population, food consumed in Scotland would contribute 12.7 MtCO2e per year
    • The estimates were calculated by summing GHG emissions from 15 stages of the food supply chain, subtracting exports and adding imports
    • The 15 food supply chain stages were: (1) UK Agriculture and Fishing; (2) Fertiliser Manufacture; (3) Imported Animal Feed; (4) Imported Food; (5) Land Use Change from Imported Food and Feed; (6) UK Food Manufacture; (7) Refrigerants; (8) Packaging; (9) Transport (UK Supply Chain); (10) Transport (Consumer); (11) Transport (Consumer Delivery); (12) Food Retail Energy Use; (13) Hospitality and Food Service Energy Use; (14) Household Energy Use; and (15) Waste Disposal
    • Of the 15 supply chain stages, UK Agriculture and Fishing (which includes GHG emissions from livestock, agricultural soils, stationary combustion sources, off-road machinery, and fishing) and Imported Food (which uses life cycle assessments and trade data to estimate the emissions for net imports) were the largest contributors to GHG emissions, together accounting for more than half of GHG emissions associated with food consumption in the UK in 2020 (Figure 4)
    • The greatest uncertainty is in the GHG emissions associated with Imported Food
    • This is due to uncertainty in land use change estimates for many Imported Food products
    • The WRAP model does not currently provide estimates for specific food groups, e.g., what proportion of GHG emissions are from meat versus other food groups
    • Between 2015 and 2020, there was a 12% reduction in GHG emissions associated with food consumption in the UK
    • GHG emissions from Food Manufacturing, Food Retail and Household Energy Use have gone down due to decarbonisation of electricity and reduced electricity demands (e.g., from more energy-efficient appliances)
    • GHG emissions from Refrigerants have gone down slightly due to use of lower-impact refrigerants, particularly in commercial settings
    • GHG emissions from Food Waste have gone down slightly due to food waste reductions and diversion from landfill
    • GHG emissions from UK Agriculture and Fishing and Fertiliser Manufacture have been largely static
    • GHG emissions from Packaging have gone up, notably increases in plastics and glass
    • Changes in GHG emissions from Hospitality and Food Service Energy Use, Transport (Supply Chain) and Transport (Consumer) were likely to be impacted by lockdowns in 2020 and so conclusions cannot be drawn on trends until subsequent years of data are integrated

    Results of the Stewart et al. (2023) model:

    • Food consumed in the UK contributed 208 MtCO2e in 2017
    • Applying the assumption that emissions are proportional to population, the food consumed in Scotland would have contributed 17.1 MtCO2e per year
    • The Stewart model combined data on food availability from FAO Food Balance Sheets with GHG emissions from life cycle assessments to estimate overall and per-capita GHG emissions for food available in the UK
    • The model does not examine different stages of the food system (production, transport, etc.) but rather the emissions attributable to the following categories:
    • Production side: changes in emissions intensity, defined as the FAO measure of emissions associated with producing a kilogram of a given product up to the farm gate
    • Consumer side: changes in consumer behaviours including dietary intake and waste at the retail and household level
    • Trade patterns: accounts for differences in continent of origin for food imports and differences in production efficiency by continent of origin, but excludes emissions from transport
    • Between 1986 and 2017, there was a 20% reduction in overall emissions associated with food consumed in the UK
    • Between 1986 and 2017, there was a 32% reduction in per capita GHG emissions
    • Changes in the production side resulted in a 21% reduction in per capita GHG emissions
    • Changes in the consumer side resulted in a 10% reduction in per capita emissions
    • Changes in trade patterns resulted in a 2% reduction in per capita emissions
    • Food produced closer to the UK did not always have lower emissions
    • Trade emissions for ruminant meat were slightly lower as it was increasingly sourced from Europe rather than from Latin America
    • Trade emissions for dairy were slightly higher
    • The UK was a net exporter of dairy in 1986 but a net importer in 2017
    • Additionally, a higher share of dairy imports were from Europe versus Oceania in 2017; and European dairy has higher production emissions than dairy produced in Oceania
    • Trade emissions for nuts and pulses were higher in 2017 versus 1986
    • The authors also examined changes in per capita GHG emissions by food group
    • Per capita GHG emissions from ruminant meat decreased by 35% from 1986 to 2017
    • Reduced consumer-side GHG emissions made the greatest contribution to this reduction, accounting for 46% of the change
    • Per capita GHG emissions from dairy decreased by 50% from 1986 to 2017
    • Improvements in production accounted for 70% of the change
    • Per capita GHG emissions from fruits and vegetables decreased by 50% from 1986 to 2017
    • Changes in the production side, consumer side and trade patterns contributed approximately equally to this change
    • Per capita GHG emissions for nuts and pulses increased from 1986 to 2017
    • This was largely due to increased consumer demand for and trade of these products

    Results of the CREDS model (Garvey et al., 2021):

    • Food consumed in the UK contributed 59.8 MtCO2e in 2017
    • Applying the assumption that emissions are proportional to population, food consumed in Scotland would have contributed 4.9 MtCO2e per year
    • Meat products, particularly processed meats, account for the largest proportion of UK agriculture emissions in order to meet UK demand for these products

    Conclusions

    This report has examined current and historical food consumption patterns in Scotland, and the implications of these consumption patterns for GHG emissions.

    Though improvements in the efficiency of food production are critical for climate change mitigation, their ability to reduce GHG emissions has limits (Stewart et al., 2023). This is because some foods have higher impacts regardless of how they are produced. The emissions from even the lowest-impact beef exceed the average emissions from milk, which in turn exceeds the average emissions from eggs and plant-based proteins (Poore and Nemecek, 2018). The Climate Change Committee therefore recommended a 20% reduction in meat and dairy consumption by 2030, increasing to a 35% reduction in meat by 2050.

    Meat and dairy are frequently consumed in Scotland by most people. However, the type of meat consumed has changed over time, and this, among other factors, has contributed to a decline in GHG emissions associated with food consumption. Specifically, since 1970, the consumption of red and processed meat, particularly beef, lamb, bacon, ham and sausages has declined. Nevertheless, red and processed meat continue to be the largest food group contributing to food system-related GHG emissions.

    With regards to total GHG emissions from food consumed in Scotland, which we extrapolated from UK models because no Scotland-specific estimates are available, there is considerable uncertainty, with estimates ranging from 4.9 to 17.1 MtCO2e. On-farm emissions account for a majority of food system-related emissions whereas transport – even when consumer transport and deliveries are included – accounts for less than 10% of emissions. As such, eating local to lower emissions may be an oversimplification of the relationship between where food comes from and environmental impact.

    For a more comprehensive and specific understanding of GHG emissions associated with food consumed in Scotland, further work is needed. In particular, to determine the nature of under-reporting in food consumption data and access to better data on where food consumed in Scotland is produced and processed. The latter would facilitate the matching of country- and product-specific LCA data (where available) to food consumption data. This is important because the efficiency of production varies substantially between countries (Crippa et al., 2021).

    Finally, future models should take into account emissions beyond those reflected in most LCA data, including packaging, hospitality and food service, household energy use, consumer transport and deliveries, and food waste management for a more holistic picture of GHG emissions associated with food consumed in Scotland.

    Secondary analysis of Scottish Health Survey (2021)

    The latest nationally representative, comprehensive data on food consumption in Scottish adults is from the 2021 Scottish Health Survey (SHeS). SHeS 2021 also included questions on the frequency of consuming fruits and vegetables among children 2-15 years old. Two publications report on food consumption patterns using these data:

    • The Scottish Health Survey Main Report, which presents information on achieving the Scottish Dietary Goals except oily fish (Scottish Government, 2022). The latest information on oily fish, which is a weekly Goal, is from the 2016 SHeS (Scottish Government, 2017).
    • A report by Food Standards Scotland on consumption of discretionary foods and drinks (Food Standards Scotland, 2023).

    The contribution of all food groups to nutrient intake has not been conducted for the 2021 SHeS. We therefore conducted a secondary analysis of these data to assess mean daily intakes and nutritional contributions of the following food groups: cereal and cereal products; meat and meat products; milk and milk products; eggs and egg dishes; fat spreads; fish and fish dishes; vegetables and potatoes; savoury snacks; nuts and seeds; fruits; sugar, preserves and confectionery; non-alcoholic beverages; tea, coffee and water; alcoholic beverages; and miscellaneous. We explored this overall and among population subgroups (based on sex, age group and SIMD and health board). Given the small sample for some health boards (Table 6).

    Summary of workshop on four published models to estimate greenhouse gas emissions associated with food consumed in the UK

    The University of Edinburgh convened a one-hour online workshop to discuss the different approaches to modelling emissions associated with food consumed in the UK. The lead authors of the four published models identified in our review attended the workshop. The discussion was in two parts: (1) the lead authors presented an overview of their modelling approach (Table 7), and then (2) the group discussed potential drivers of differences across models in estimated greenhouse gas emissions associated with food consumed in the UK (Table 8).

    Model

    Summary of approach

    WRAP

    Builds the estimates using sector-specific information from published UK inventories of emissions, rather than LCAs of specific foods consumed. Current area of focus is improving the estimates of imported food emissions, with future intentions to look at the potential impact of on-farm mitigation in the UK.

    Several strengths of this approach, including:

    • Ability to capture hospitality, cooking at home, and food waste management [which are typically not reflected in cradle-to-retail gate LCAs]
    • Ability to update estimates every year to account for shorter-term changes, e.g., in the electricity grid, whereas LCAs are often ‘static’ to a particular year

    LCAs are used for imported food and are, in some cases, specific to country of import – where there is reason to believe there would be a substantial impact, such as beef and lamb. Further work for this model will focus on improving estimates for traded food and the associated emissions, looking at creating more specificity for products coming from certain locations, and integrating international transport.

    However, it is not without limitations:

    • Cannot look at population subgroups
    • Harder to look at food groups; could be done using other datasets not currently included in their model but this is outside their current scope of work
    • Land use change is currently focused on specific commodities such as palm oil and soya; this could be improved

    Data sources:

    • Governmental datasets such as UK inventories for agriculture and energy consumption by sector (manufacturing, food, retail, etc.)
    • Other data filled in, e.g., for household deliveries, hospitality, and refrigerant specific emissions
    • UK trade data linked to LCAs for imported foods

    Stewart

    This model matches food consumption data to LCAs to estimate emissions. FAO data on food supply, production, imports, exports, seed and feed, were combined with Poore and Nemechek (2018) LCA data.

    Several strengths of this approach, including:

    • LCAs were disaggregated by continent and updated over time to reflect variability between continents and over time in emission intensities for commodities
    • Able to look at food group level data
    • Able to quantify changes in emissions from changes in consumption versus production efficiency versus trade

    However, a limitation is that it does not include emissions from hospitality, cooking at home, consumer transport and deliveries, etc.

    Data sources:

    • FAO Food Balance Sheets
    • FAO emission intensities
    • Poore and Nemechek (2018) LCA data

    Bates

    This model uses a database of emissions linked to NDNS food consumption data, originally developed for the University of Newcastle’s Intake24 dietary recall tool in order to provide feedback to survey participants on the environmental impact of their diets.

    The model strengths are:

    • GHGs were mapped from the largest number of unique foods and beverages than any previous UK study at the time
    • GHGs (CO2e as g/100g) were matched to the majority of individual foods in the NDNS database
    • Able to look at consumption by food groups and by population subgroups.

    Data sources:

    • Published studies and company websites for LCA data
    • NDNS for food consumption data

    CREDS

    Primarily purpose was to explore the potential of demand-side mitigation. The model explores three consumer-facing strategies: shifting to plant-based diets, following UK dietary recommendations, and reducing food waste. NDNS data were used for consumption levels by product, whilst the Family Food Survey was used for the calorific intake estimates. The correction for under-reporting was applied on a calorific basis. The representation of diets was based on 17 dietary profiles outlined in the academic literature.

    There are 69 food product categories covered by the model, using the Classification of Individual Consumption by Purpose (COICOP) classification system. UK MRIO model captures all process-based emissions and factors per food category expressed as emissions per £ spent. Whilst there are uncertainties in most input-output based modelling approaches, the UKMRIO model does incorporate import data from 15 world regions (based on data from 50 countries). This also reflects differences in agricultural production techniques (and consequently emissions factors) from each region. This model does not capture emissions associated with cooking or waste management, land use, or agricultural efficiencies, but subsequent iterations of UK MRIO do take into account land use change.

    Data sources:

    • NDNS, Family Food survey and literature reviews to describe example diets
    • UK MRIO model
    Table 7: Summary of modelling approaches used to estimate the greenhouse gas emissions associated with food consumed in the UK.

    Aspect of model

    Summary of differences

    Land use change emissions

    WRAP and Stewart are the only models that include emissions from land use change

    Packaging, hospitality sector, and post-retail emissions

    WRAP is the only model that includes emissions from packaging, hospitality sector, and post-retail (e.g., home food preparation, consumer transport and deliveries, food waste management)

    Under-reporting of self-reported food consumption

    • Tendency to under-report in food diaries used in Bates and CREDS
    • CREDS did make a simple adjustment for under-reporting in their model

    Handling of imported foods

    • Concerns regarding the accuracy of the FAO trade database used in Stewart model
    • Uncertainty on country of origin data and farming systems (thus associated emissions) for imported foods – applies to all models
    • WRAP did some analysis around tracing country of origin and found that even when tracing a food product, if it does not come from our first trade partner, the second and third are often the same. For example, The Netherlands is our fourth-largest trade partner for palm oil, but they mostly import from the same top two trade partners as the UK (Indonesia and Malaysia). There were some anomalies, but for most, the import chain did not appear to make much of a difference
    • Stewart did a sensitivity analysis accounting for continent and found it varied by food group. For example, with beef, accounting for continent increased emissions by 25% (i.e., imported meat has higher emissions on average than UK produced beef), but with mutton, it decreased by 28% (i.e., imported mutton has lower emissions on average than UK produced mutton)

    Pasted verbatim from supplemental material:

    “Data on 2017 expenditure by COICOP food groups was used to calculate emissions.

    The ONS produces Supply and Use Tables (SUT) on an annual basis at a 106 sector disaggregation (ONS, 2018). The use tables are ‘combined’ tables, which means that the inter-industry transaction table is the sum of both domestic transactions and intermediate imports, and the final demand table shows the sum of both domestic and imported final products. Less frequently, the ONS produces a set of analytical tables containing both domestic use and domestic final demand tables. From these tables, we can extract the proportion of domestic spend and produce domestic use and domestic final demand tables from the annual SUT tables, which span a greater time period. Any Imports to intermediate industries are shown as a single row of data and the exports to intermediate and final demand as a single column of data.

    Data is extracted from the EXIOBASEv3.6 MRIO database (Wood et al., 2015) to disaggregate the import and export data to further sectors from other world regions. EXIOBASE data can also be used to show how foreign sectors trade among themselves, but the data must first be converted to Great Britain Pounds (GBP). The first step is to map the EXIOBASE MRIO database onto the UK’s 106 sector aggregation. Once this has been done, the data can be further aggregated by region. Since EXIOBASE contains data from nearly 50 countries and regions, we can select the most appropriate regional grouping for the trade data. For this MRIO study, we construct fifteen regions: UK, Brazil, Russia, India, China, South Africa, USA, Japan, Rest of the European Union, Rest of Europe, Rest of the OECD, Rest of Africa, Rest of Americas, Rest of Asia, Rest of the Middle East.

    The UK is unusual because the SUTs constructed by the ONS include final demand by UK households that is split by both product sectors in the IO structure and 42 COICOP sectors which are also found in the Annual Living Costs and Food (LCFS) survey (see Figure S1). This means that we can be confident in linking these datasets. The UK is unusual in providing this bridge table between the two formats of recording spend by products. In other studies much work has gone into the construction and evaluation of these bridge tables (Steen-Olsen et al., 2016; Min and Rao, 2017) but because the LCFS is in input to the national accounts, the ONS can supply this mapping at an aggregate scale.

    The UKMRIO database contains information on how all UK households spend for 306 COICOP categories. To do this we use data from the 2016 LCFS (UK Data Service, 2019) which shows weekly expenditure by the 5,041 households involved in the survey. The LCFS is used to provide information on retail price indices, National Account estimates of household expenditure, the effect of taxes and benefits, and trends in nutrition. The survey strives to produce a representative sample of the 27 million UK households in 2016. We use this data to portion total UK household expenditure by top level COICOP category in the UKMRIO database.”

    19. Forests and peatlands store carbon, and so when they are destroyed for livestock grazing or agriculture, they release carbon into the atmosphere. If, in the process of destroying forests and peatlands, they are burned, the burning results in additional emissions. In addition to GHG emissions from these land use changes, microbes in soils can produce GHG emissions. For example, when fertiliser is applied to pastures or crops, microbes in the soil break it down in a process that produces a GHG called nitrous oxide.


    The Climate Change Plan update sets out targets to reduce emissions from the agriculture sector. Carbon dioxide emissions associated with stationary combustion sources and off-road machinery use in agriculture contribute significantly to agricultural emissions and have increased between 2020 and 2021.

    Executive summary

    Background

    The Climate Change Plan update sets out targets to reduce emissions from the agriculture sector. Carbon dioxide emissions associated with stationary combustion sources and off-road machinery use in agriculture contribute significantly to agricultural emissions and have increased between 2020 and 2021. Fossil fuel use for agricultural machinery is estimated to contribute 5 to 10% of agricultural greenhouse gas (GHG) emissions in Scotland.

    The impact of agriculture’s energy use can be difficult to account for, with emissions being captured within grouped sectors (electricity, gas and other) of the GHG inventory. This report examines the energy use and associated emissions baseline on farms and crofts in Scotland, and explores the potential for efficiency measures and new, low-carbon technologies to support energy emissions reductions in the longer term.

    Key findings

    • 82% of the emissions from agricultural energy use stem from other energy sources such as coal, liquefied petroleum gas (LPG) and oils, and 18% from electricity. This is based on the local authority greenhouse gas statistics where emissions are allocated to where the electricity is used, not where it is generated.
    • The greatest source of emissions from other energy sources is the livestock sector; within this, beef has the greatest energy emissions due to the dominance of this sector in Scotland; dairy has the greatest intensity of emissions per kilogram of production.
    • The first step in the decarbonisation journey is to look at opportunities to reduce energy use. There is great scope for energy efficiency measures to contribute to decarbonising agriculture. This can be achieved through optimising processes and introducing new technologies such as robotics and precision farming.
    • Reducing other energy emissions by fossil switching to electricity will have a large positive impact. Replacing machinery with electric-powered equivalents will reduce cost and carbon emissions in the long term. Whilst electric replacements are not yet suitable for all farm operations where high power is needed, there are viable alternatives for smaller vehicles such as quad bikes, which are already being used across Scotland.
    • The cost and carbon benefits of switching to electric-powered machinery may be optimised by combining this with on-farm renewable power generation.
    • A good mix of low-carbon and renewable energy generation technologies is available across Scotland, which have generally high uptake and market readiness, and strong applicability to the agricultural sector.
    • For most farmers, the introduction of renewable technologies is an incremental process. Each investment decision must provide a good business case. As farms build their renewable capacity, there is the potential to develop further into micro-grid or distribution network connections.
    • Upgrades to energy distribution networks infrastructure could enable more farmers to export energy and accelerate decarbonisation beyond the farm.

    Conclusions

    The research identifies the wide variety of technologies available to meet the diversity of on-farm needs for energy efficiency, energy generation and energy use. These can all have a significant impact on reducing carbon emissions in the agricultural sector.

    The cost of implementation is often an important factor for installing energy technologies. Many energy and process efficiency measures can be implemented on farm with low investment needs. However, the typically high upfront investment costs to install renewable energy generation on farm is frequently noted as a barrier for some farmers.

    Another challenge is the limitations on the energy distribution networks. As a result, some businesses are not able to export energy back to the grid depending on their location and logistical constraints.

    There are great opportunities to further decarbonise energy use and generation in the agricultural sector. In the correct enabling environment, farms can play a significant role in supporting Scotland’s net zero targets, just transition and circular economy aims.

    Introduction

    There are great opportunities for agriculture to play a leading role in the just transition to a low carbon economy. From the implementation of low carbon technologies, application of alternative fuels, and use of energy efficiency measures, agricultural businesses will be able to benefit from decarbonisation through reduced energy use, more efficient processes and technologies, and on-site clean energy generation. Scottish agriculture could also function as an enabler of wider decarbonisation if surplus energy can be generated to meet off-site market demands.

    The decarbonisation of energy use and a transition to low carbon energy generation within the agriculture sector is an essential consideration for Scotland to:

    • Meet the 2030 interim 75% emissions reduction target, and the 2045 target for the country to reach net zero GHG emissions.
    • Support Scottish Government’s commitment to creating a circular economy which supports GHG reductions from manufacturing and transportation and develops safeguards against potential future resource shortages.
    • Support Scottish Government’s vision to become a global leader in sustainable and regenerative agriculture.

    As detailed in the Climate Change Plan Update 2018-23[1], Scotland has an abundance of renewable resources. More than 87.8% of the electricity generated in Scotland during 2021 came from renewable and low carbon sources, and there is scope to go further. There are opportunities for the agricultural sector to both decarbonise its own activities and to also play a strategic role in decarbonising energy used across Scotland.

    The Scottish Government is committed to ensuring a just transition to a low carbon, climate resilient economy, as outlined in the draft ‘Energy Strategy and Just Transition Plan’[2]. It is particularly vital now as the climatic changes signal the urgency with which we need to act, whilst at the same time the cost-of-living crisis is putting real pressure on government, householders and businesses. Scotland has already taken steps to support a just transition, including setting up the first Just Transition Commission (JTC) which made twenty-four recommendations in March 2021[3]. These were all accepted by the Scottish Government and include recommendations such as:

    • establishing a just transition plan for Scotland’s land and agriculture, with clear milestones to 2045, supporting Scottish agriculture to deliver climate action; and
    • committing to creating communities that embed low-carbon lifestyles.

    The agriculture sector and land-based economy is highly vulnerable to climate changes[4],[5]: recent unpredictable weather, from the ‘beast from the east’ to 2022’s unusually dry conditions have all had a huge impact on productivity and farm incomes. Farmers and crofters have also been hard hit by price rises resulting from the war in Ukraine and the disruption to the labour market post-Brexit. Many producers in energy intensive sectors such as poultry and horticulture responded to this by pausing or reducing production rather than risk producing at a loss.

    There are significant opportunities for agricultural businesses to benefit from low-carbon energy generation. The potential to reduce costs of generate revenue will vary from business to business; examples of potential benefits are:

    • Introducing more efficient processes and technologies will reduce the overall energy requirements so saving money and reducing emissions.
    • Replacing machinery and vehicles with electric equivalents may provide cost savings for the business in the long-term and significantly reduce agricultural emissions. Cost benefits are further optimised if the business can utilise their own energy generated from on-farm renewables.
    • Installing renewable generation technologies means farms can become more self-sufficient and resilient to fluctuations in energy supply costs.
    • New opportunities for a diversified income stream through the production of energy on-farm or through leasing land for renewable energy generation.

    Aim

    This report maps out the baseline for current energy used on farms and crofts in Scotland using National Atmospheric Emissions Inventory (NAEI) data and sets out the available evidence base and gaps. Secondly, the available literature of opportunities and barriers for low carbon energy production and use on Scottish farms is assessed, and any evidence gaps and topics of debate are documented. Finally, the study analyses the strengths, weaknesses, opportunities and barriers for specific technologies, and the various factors that enable or prevent current and future uptake.

    Energy use baseline and generation sources

    Estimation of emissions

    This report has taken the approach to estimate the on-farm emissions from energy use based on local authority (LA) breakdowns. As part of the National Atmospheric Emissions Inventory (NAEI[6]), emissions of greenhouse gases (carbon dioxide, methane, nitrous oxide) are calculated at LA level on an end user basis[7].

    Using this approach, estimates from energy use in agriculture for 2021 are shown in the table below (kt CO2 equivalent), taken from the LA statistics and aggregated to agricultural regions. Further details of energy use may be found in Appendix A of this report.

    Table 1: Electricity, gas, and other fuel emissions estimates for 2021 shown in kt CO2e. This table covers everything from the inventory, including both rural and urban estimates. For our estimations covered in the following tables, we excluded urban areas to reduce anomalies in the data.

    As the data from the NAEI is not broken down by livestock or crop type, the Scottish agricultural census[10] (which provides the head count of livestock and hectares of crops at regional level[11]) has been combined with typical fuel consumption factors (detailed in section 9.1.1 of this report). This was used as a proxy to disaggregate and spatially resolve the above GHG energy emissions (Table 1) into crop and livestock type by region. This provides a breakdown of rural emission estimates for electricity, gas and ‘other’ (urban emissions were removed). ‘Other’ fuels include coal, liquefied petroleum gas (LPG) and oils for static and mobile machinery. These emissions are calculated on an end user basis. Emissions are allocated to where they are used, not where they are generated.

    The energy emissions by agricultural region in the livestock and crop sectors are presented in the maps and tables below. A full methodology can be found in Appendix A. The table below shows a summary of energy use emissions across Scotland by sector. Their implied intensities have been calculated (CO2e emissions divided by headcount/hectare total) to facilitate meaningful comparisons.

    The livestock sector accounts for approximately 63% of the energy use emissions of agriculture in Scotland. Beef has the highest overall energy emissions when compared to all other sectors, emitting over 100 kt CO2e more than the dairy sector, which is the second largest CO2 emitting sector. This is largely due to the scale of beef production in Scotland. The table above is ranked by the emissions intensity; the greatest emissions per head (emissions intensity) is from dairy production, which is more than twice as energy intensive as beef. When looking at the data above it is important to note that energy is a significant cost to intensive poultry production, but due to the number of birds per shed it is not well represented in this intensity figure. However, it would be significant if we looked at energy intensity per hectare of production.

    The table below shows some of the typical energy uses on livestock farms.

    Table 2b: Typical energy uses in the livestock sector.

    Energy requirements

    Dairy

    Chillers, heating, lighting, small amount of warm/hot water. Some mobile (e.g., spreaders, HGVs needed for on-farm feed production). Some energy needs for robotic milking.

    Poultry (layers)

    Heating, cooling, and ventilation systems in housing.

    Poultry (broilers)

    Heating, cooling, and ventilation systems in housing.

    Broilers – high demand on day 1 – diminishing heat demand as birds grow, but ventilation demand increases.

    Pig

    Housed pigs- Intensive heat and lighting energy use.

    Sheep

    Small amount on mobile machinery, small amount of electricity or fuel for a generator for sheering machinery. Small amount heating and light for lambing and small amount of warm/hot water for washing.

    Beef

    Low demands, similar to sheep. Small amount on mobile machinery. Small amount heating/lighting for calving and for small amount of warm/hot water for washing

    Cropping and horticulture accounts for approximately 37% of the energy use emissions from agriculture in Scotland. Within the cropping and horticultural sectors, spring barley had the greatest emissions and produced more emissions from energy use than some livestock sectors, such as sheep, pigs, and poultry. However, emissions associated with the production of potatoes are shown to be the most intensive when area of production is taken into account. The table below covers the typical energy uses in cropping and horticultural sectors.

    Table 2d: Typical energy uses in cropping/horticulture.

    The maps below show the energy use emissions associated with livestock and crops across Scotland, indicating the areas with greater or fewer emissions from either sector.

    Figure 1: Emissions (kt CO2e) associated with livestock (left) and crops (right) at regional level in Scotland.

    As can be seen from figure 1, the largest emitters of energy emissions associated with livestock are located in the southwest of Scotland (Dumfries & Galloway and Ayrshire); the same areas are low emitters of emissions associated with the growing of crops.

    For energy emissions associated with crops, Eastern Scotland (Grampian) is the largest emitter. However, this area also has the highest number of hectares of crops in Scotland and it can be noted from figure 2 below that this area is one of the most efficient in terms of CO2e per hectare. The east of Scotland is generally more efficient for both crops and livestock than the western or northern parts of Scotland.

    Conversely, Argyll, Orkney, Shetland, and the Outer Hebrides are areas of low crop related emissions but high intensity of CO2e per hectare, however this may be a reflection of low numbers of crops grown in those areas.

    Figure 2: Relative emissions (kt CO2e) associated with livestock (left) and crops (right) at regional level in Scotland.

    The table below (Table 3) shows the emissions by livestock and cropping sectors for each LA. Electricity emissions have come from the NAEI Local Authority GHG (LA GHG) data. Proxy data has been applied to the LA GHG emissions to split it into the different agricultural sectors. The table shows that for each region the emissions from other energy inputs (including coal, liquefied petroleum gas (LPG) and oils for static and mobile machinery) exceed those from electricity use.

    This report estimates total on-farm emissions from energy use to be 1.1 MtCO2e. However, energy emissions in the agriculture sector in Scotland as reported in the UK National Atmospheric Emissions Inventory (NAEI) were 0.91 MtCO2e in 2021. The vast majority of these emissions reported in this figure (0.91) relate purely to emissions associated with mobile machinery, such as tractors, harvesters and other on-farm vehicles. A smaller amount of these energy emissions are related to energy combusted by static machinery; for example, generators, grain dryers, chillers, or robot milkers.

    Emissions from the NAEI are reported in a variety of different formats for different purposes each year. One of these is the end user format (used in this report) in which emissions from the production and processing of fuels, and the production of electricity, are reallocated to final consumers of the energy to reflect the total emissions relating to that energy use. This difference in reporting mainly affects emissions related to electricity generation from power stations and fuel processing in refineries. This is in contrast to the ‘by source’ or ‘by territory’ emission reporting (in e.g., the devolved administration (DA) inventories) in which emissions are attributed to the sector that emits them directly.

    In the LA statistics, the end user estimates are calculated using postcode level gas and electricity meter readings, in conjunction with employment statistics in the calculation. There are various spatial distributions that may be aggregated to the LA level[12]. This subsequently provides a spatial estimate of electricity, gas and other fuel use in Scotland. Consequently, this will pick up non-farm energy use on farm buildings, such as holiday rentals, as well as all mobile machinery and static combustion elements. The purpose of this is to demonstrate the broader potential for low energy production on farms to reduce emissions from energy use. As a result, the estimation of baseline emissions using this approach as higher, at 1.1 MtCO2e, than those reported in the UK NAEI for Scotland.

    In summary, the approach used in this report uses the LA dataset as its starting point, and the results will therefore differ from any other published data, such as the 0.91 MtCO2e figure, which uses a different/by source dataset (e.g., DA inventory) as it’s starting point.

    Summary remarks based on the estimation of emissions

    Table 3 indicates that efforts to reduce agricultural emissions would be most effective if targeted at processes that currently rely on other fuels. This may be through identifying opportunities to improve the efficiency of these operations or technologies that enable the electrification of processes that previously relied on fossil fuels. Decarbonisation will be further optimised if the electricity used is generated through renewables.

    82% of the emissions from agricultural energy use stem from other energy sources (coal, liquefied petroleum gas (LPG) and oils), and 18% from electricity. From the data, it is evident that livestock ‘other energy’ emissions are a substantial contributor to the overall energy use emissions from agriculture in Scotland. Efforts to reduce this through efficiency measures or fuel switching will have a significant impact. This is illustrated in the figure below, which provides a snapshot of the sources of energy use emissions for the agricultural sector overall and split by cropping and livestock sectors in Scotland.

    Figure 3: Sources of energy use emissions for agriculture overall and split by sectors.

    Gaps in baseline estimate

    The literature provided data on the typical energy consumption of various sectors; however, the dominant fuel (or mix of fuels) used within the ‘other’ energy consumption category is less well documented. For example, although the use of petroleum products is widespread in the poultry sector (particularly for heating), there is little data on the relative proportional use of these products. There is a need to gather more detailed information on the use of petroleum products for various agricultural practices to better understand these gaps in the future. Similarly, there is limited information on the use of individual electricity generators and their fuel consumption.

    Most data found in the literature are from 2005, as more updated benchmarks containing the energy consumption breakdown required were not publicly available. However, it was found that mobile machinery benchmarks (as shown in Table 9.1.1) remained the same in the literature between 2005 and 2023, suggesting the non-mobile machinery 2005 statistics are still relevant and provide a reasonable basis for calculations.

    While the literature provided specific data on the majority of sectors, some were not explicitly defined in terms of energy consumption. For example, the sectors of ‘oilseed and linseed’ and ‘peas and beans’ were included in a broader ‘other arable’ category that also contained sugar beet. Furthermore, the literature contained energy consumption values for sows is derived from energy inputs associated with maiden gilts, piglets, and boars. Therefore, no consumption values were attributed to non-breeding pigs as these were incorporated into the sow data.

    Evidence base

    A Rapid Evidence Assessment (REA) of peer-reviewed and grey literature was used to evaluate renewable energy technologies currently adopted in Scotland. The methodology can be found in Appendix 2. This evidence was supported by the expert knowledge of the project team. The review focused on identifying:

    • Barriers and enablers of technology specific to the agricultural sector to reduce demand for fossil fuels and support the decarbonisation of on-site energy use.
    • Opportunities and benefits for the agriculture sector to support the wider decarbonisation of energy production at a systems level through renewable energy production.
    • Current potential for the agricultural sector to benefit from an emerging second-hand market for renewables and renewable components and opportunities for the farming community to participate in a circular economy, such as reusing and repurposing alternative energy components.
    • Land use implications from low carbon energy production with a focus on farms (but with a consideration of wider landscape impacts), and the potential impact on agricultural production.

    The following sections discuss information found in the REA, covering renewable energy technologies relevant to Scotland which are ‘areas of confident knowledge’, including a summary table of technology applications and details such as market uptake and cost; key evidence gaps highlighted from the REA; and areas under active debate.

    Reducing the demand for fossil fuels and supporting the decarbonisation of on-site energy use

    Energy efficiency

    The first step in a decarbonisation journey is to look at opportunities to reduce energy use and support or enhance energy efficiency. There are many agricultural businesses in Scotland for whom this will provide opportunities for reducing energy use. Typically, implementing energy saving measures provides long-term cost savings and many can be low or no-cost to implement, though some will require a more significant investment. Energy consumption and opportunities to save energy vary considerably between businesses, depending on the operating farming system and the efficiency with which the system is managed.

    Teagasc[13] report that energy costs in dairy farms vary from €15-45 per cow per year; this variance indicates the scale of opportunity for efficiencies. The Carbon Trust[14] note that key areas of energy consumption (and therefore areas in which efficiency measures will have most the impact) are lighting, heating, ventilation, air circulation, and refrigeration.

    The following table provides an overview of energy efficiency technologies that can be deployed across a range of farm sectors in Scotland[15].

    Robotics

    A number of the measures detailed above are automated or robotic. It is not yet considered achievable to have fully autonomous, robotic, energy-independent farms (Ghobadpour et al., 2022) but robotics are an important set of technologies that can support low-carbon agricultural production systems.

    Robotics and Autonomous Systems (RAS) enable greater farming accuracy, lightweighting of machinery (which has a co-benefit of enabling positive environmental benefits) and, in comparison to humans, a longer work time, enabling great efficiency (Krishna, K.R., 2017). An EU foresight study predicted that around 50% of all European herds will be milked by robots by 2025 (Duckett et al., 2018). Robotic systems are also starting to perform other tasks around the farm, such as removing waste from animal cubicle pens, and carrying and moving feedstuffs. Other RAS already in use include GPS driven tractors and systems for autonomously monitoring livestock and collecting field data, which are all commercially viable and useful for efficient and productive livestock farming. These are just the start; there are considerably more robotic applications under development, although most agricultural RAS are currently far from commercialisation (Gorjian et al., 2021)

    Despite the clear value of robotics, there is limited information in the literature discussing the ability for RAS to contribute to the decarbonisation of the agriculture sector in Scotland. A causation could be because the UK Agri-Food RAS community is still small and highly dispersed (Duckett et al., 2018).

    Electric vehicles

    Agricultural battery electric vehicles (BEVs) have the potential to provide numerous benefits such as emission reduction, low operating costs, on farm charging, and vehicle-to-grid technology creating a new source of income. In the long-term, it is likely that BEVs will be the preferred technology for replacing current diesel-powered internal combustion engine machinery; however, Baker et al. (2022) found that there is a lack of international progress in encouraging the uptake of low-emission machinery. Nevertheless, this means there is an opportunity for Scotland to set a standard in encouraging low-emission machinery.

    The most common debate found in literature is whether battery powered agricultural vehicles are a practical solution in agriculture, with many stating that currently, electric vehicles (EV) are not suitable for use in agriculture (Baker et al., 2022). However, this comment is generally associated with larger EVs on farm, such as electric tractors. Electric quadbikes, all-terrain vehicles (ATVs) and 4x4s have been on the market for several years and are gaining popularity due to the low-cost of charging compared to conventional mobile machinery and quieter operation. Electric ATVs are a prime example of EVs that work well within the sheep and beef sectors in Scotland, where livestock are often located in the uplands and highlands.

    The debate around the suitability of larger EVs (e.g., tractors or combine harvesters) in agriculture generally stems from the low energy density, heavy batteries and if they can take over from diesel powered vehicles with the nature of agricultural work. The energy density of lithium-ion batteries (circa 200Wh/kg is significantly lower than diesel (11.6kWh/kg)) (Pearson et al., 2022). An average tractor diesel engine requires a 400l energy reserve of fuel (9.8 kWh/l resulting in a total of 3,920 kWh or 1,670 kWh due to the 40-45% engine efficiency). The equivalent full electric variant utilising Lithium-Ion (Li-Ion) batteries (best values of the battery pack expected in 2025, midterm 0.2 to 0.25 kWh/kg), results in a total of 2,000 kWh due to the high battery efficiency, weighs 9-10 tonnes and takes 5,000 l in volume to do the same 8 hours of work[16]. Despite batteries being more energy efficient, this still leads to several concerns:

    • Heavy batteries limit the range and usage of agricultural machinery and can increase soil compaction if the vehicle weight is not effectively distributed through vehicle design, leading to a range of environmental and productivity issues on farm.
    • There is a debate surrounding the environmental impact of battery production, in particular the procurement of the rare materials and minerals required[17].
    • Charge time is another concern under debate, with heavy, powerful machinery requiring significant time to charge. Although this can be overcome with powerful charging infrastructure, this comes at a cost. Farmers may also overcome this with reduced operation time or multiple charging sessions, both of which however do not make for an economically competitive case against the diesel counterpart (Baker et al., 2022).

    Currently there is reluctancy to adopt EVs without incentives (such as grants, subsidies and market price) (Jones et al., 2020) and whilst there is evidence to support the suitability of EVs for small scale horticulture, indoor fruit growing, and grounds maintenance activities (supporting the main driver that smaller electric machines allow farmers to undertake activities indoors and close to the farm40), there is a current inability to support all farming activities (Baker, P., et al 2022). As a result, some believe the current constraints will result in large internal combustion engine vehicles remaining in use for many years to come (Duckett et al., 2018), while others believe low carbon fuels and/or hybrid systems incorporating a combustion engine and a battery may be one possible technological solution.

    Although energy and process efficiency is a starting point to reduce energy use, the benefits to the business and to the environment may be further optimised if the business is also able to explore combining energy efficiency with renewable energy production. In the right setting and application, this can provide significant cost savings in the long-term and a reduction in GHG emissions.

    Opportunities to support the wider decarbonisation of energy production

    There are a range of renewable technologies relevant to Scotland that are already installed across the country in various agricultural settings. This section discusses those technologies and provides an overview of their applications in the agriculture sector. Tables 4 below provides an overview of different alternative energy generation and use technologies on farm, covering the following details: energy vector, sector coverage, market readiness, current installed capacity in Scotland, capital expenditure (CAPEX) and operating expenditure (OPEX) per annum (pa), quantified CO2 abatement potential (for individual installations, rather than the nation-wide abatement potential), and the public acceptability of installations based on survey data.

    Where the table states ‘n/a’, there was no available data. The availability of this data shows that there is a need for further surveying of public opinion on the acceptability of anaerobic digestors, for example. Market readiness relates to how ready the technology is to enter the market; those that are already widely available are noted as ‘high’, and those that aren’t widely available are defined as ‘low’ (where information was available).

    Solar

    Solar PV capacity increased rapidly in Scotland between 2010 (2MW) and 2016 (326MW) but the pace slowed thereafter, reaching a capacity of 522MW by March 2023[21]. Solar energy holds much potential as a renewable energy source for on-farm agricultural operations (Gorjian et al., 2021). In Scotland, solar energy has been utilised in a variety of ways, including the use of solar PV to power on-farm cold stores for potatoes and providing electrical supply to remote farm buildings (Muneer & Dowell, 2022).

    Throughout the literature it is noted that solar is a popular renewable technology within the poultry industry (Sutherland et al., 2017). An example of this is a farm in eastern Scotland producing 215,000 Ross broilers, which uses solar energy to power the ventilation systems and move feed in their seven shed production system[22]. Further examples include the establishment of solar panels within fields typically used for pasture and silage production, such a set up allows for livestock to continue grazing within these fields[23].

    In some instances, solar installations may occupy land better suited for agricultural production. A potential opportunity to combine low-carbon energy production and agricultural production simultaneously is agrophotovoltaics (APV), or agrovoltaic energy. APV systems consist of solar panels integrated within productive agricultural land. In arable applications of APVs, the APVs protect the crops against the sun’s heat and reduce evapotranspiration in the soil. In pastoral systems the APVs provide shade for livestock in hot weather. This option may be more suitable to warmer climates, but with a changing climate it is important to consider the range of climate smart agricultural adaptation measures that can be deployed on farms. Such systems are predicted to increase land values and productivity for producers by 35-73% (Rahman et al., 2022).

    There is additional potential for the development of solar powered vehicle charging and electrical storage. Rooftop and ground-mounted solar chargers have been on the market for well over a decade[24]. Currently, charging points largely exist within private and public settings for electric vehicles. Over the next four years, the Scottish Government is providing £28 million for the manufacturing and deployment of zero emission, heavy duty vehicles[25]. A more niche market of ‘solar carports’ for on-farm vehicle charging is slowly developing in the UK. However, more research is required on its applicability for agricultural vehicles, particularly for energy storage and charging technology (Ghobadpour et al., 2022).

    Wind

    In Scotland, onshore wind forms the largest single technology provider of renewable energy. Significant advances in research and the development of wind energy have increased production over the last 20 years. In 2022, wind was responsible for generating a total output of 21,975 GWh, accounting for 62% of all renewable electricity generation in the country[26].

    The introduction of renewable obligation certificates (ROCs) in 2002, led to an increase in the economic viability of wind energy generation for large-scale projects (more than 5MW) on farms (Sutherland et al., 2015). ROCs formed part of the domestic energy and climate change policy, implemented to encourage investment in renewable electricity generation. Feed-in-tariffs (FIT) were later introduced in 2010 by the UK government in favour of small to medium-scale projects (less than 5MW) with both ROCs and FIT guaranteeing electricity prices, thus further contributing to the uptake of wind turbines. However, the literature identifies that the reductions in feed-in-tariff payments (due to rapid uptake in recent years) led to much uncertainty amongst farmers wanting to invest in renewables (Sutherland et al., 2015). It is hoped that this has been negated by the introduction of both Contracts for Difference (CfDs) and the Smart Export Guarantee (SEG) scheme.

    CfDs were implemented as the government’s main scheme for supporting large-scale, low carbon renewable generation. CfDs aim to incentivise developers to invest in renewable energy by protecting against volatile wholesale prices, whilst also protecting consumers against rising electricity prices[27]. The SEG scheme came into effect in January 2020. This is a government-initiated tariff for businesses and homes who have installed small-scale renewable or low carbon technology which enables them to receive payments from electricity suppliers for surplus electricity exported to the electricity distribution network[28].

    Wind energy presents farmers with the opportunity to lease out land to energy producers on an annual basis or alternatively to produce energy and sell back to the electricity market any surplus energy that is not used directly on the farm (Albanito et al., 2022). Commercial wind farms can be found extensively throughout Scotland and work well in remote locations due to windy weather conditions. Large concentrations of turbines tend to be found towards northern latitudes and the uplands (Shepherd et al., 2021). Agricultural holdings characterised by large areas of crop and fallow land, mixed agricultural land, improved grassland, livestock grazing, and other areas of low agricultural value are well suited (Ge et al., 2017). The appropriate siting of wind farms is crucial. Care needs to be taken that wind turbines are not situated on pristine and deep peatlands. The disturbance during construction releasing large quantities of CO2 from peaty soils, negating the effect of reducing overall emissions[29].

    Small-scale wind power offers numerous opportunities within off-grid use in agriculture. In more rural areas where electricity distribution network connectivity is lacking or too expensive, the use of small-scale (5 to 50kW) and stand-alone turbines have become increasingly important [30]. Small wind turbines can be used in a similar way to photovoltaics, for example:

    • to charge on-farm batteries
    • for the heating or pumping of water
    • electric fencing for livestock
    • lighting and
    • functioning of small electronic systems[31].

    Wind power remains a popular option for renewable energy production for both wider consumption and local use given its reliability, low maintenance costs and design lifetime. Throughout the literature there remains much debate over the competition for use of land in agriculture, both in terms of function (food versus fuel), as well as control (farmer versus corporation). This is discussed in greater detail in section 5.4. The use of pastoral land or marginal land negates the loss of crop area and reduces the risk of farm machinery damaging wind turbines. Furthermore, given that livestock are capable of grazing underneath these turbines, producers can continue to graze land with limited land area lost to turbines, substations, and access infrastructure (Shepherd et al., 2021).

    The effectiveness of this technology ultimately depends on the average wind speed and the need for energy storage mechanisms (Ghobadpour et al., 2022).

    Bioenergy

    Bioenergy refers to use of organic material to produce electricity or heat or to make fuels. Bioenergy can come in various forms, including solid biomass, biogas or liquid biofuels. In the context of Scottish agriculture, many farms have adopted solid biomass boilers which burn virgin wood chips, pellets, or logs to heat poultry sheds, farm buildings or workshops, on-farm residential buildings, and greenhouses, and to dry grain, for example.

    Alternatively, biogas (a mixture of methane and carbon dioxide) can be produced from agricultural residues such as animal manure, crops, and crop residues via anaerobic digestion (AD). The resulting biogas can be combusted in a boiler or in a CHP engine. According to the National Farmers Union (NFU), farms host over half of the Great Britain’s AD capacity[32].

    Both solid biomass and AD have been supported by the Non-Domestic Renewable Heat Incentive (RHI) which was effective since 2011 but closed to new applicants in 2021. According to Non-Domestic RHI statistics[33] which represents installations across Great Britain, more than 30% of RHI capacity is in the agricultural sector (the sector with the greatest uptake of the scheme). Across the full duration of the scheme, solid biomass boilers account for 77% of all applications. However, in recent years the share of biomass boiler applications has reduced. In 2022, 58% of applications were solid biomass with heat pumps forming the second highest share at 39%.

    The UK Government’s Green Gas Support Scheme (GGSS) launched in late 2021 to support AD sites who upgrade biogas to biomethane and inject this to the gas grid. Farmers can utilise this opportunity by selling their feedstocks to a biomethane plant. Some farms which are located on the gas grid may wish to inject biomethane directly into the grid themselves. An updated UK Biomass Strategy[34] was published in August 2023, which outlines a priority use framework for the best uses of sustainable bioenergy across the UK. Meanwhile, the Scottish Government planned to release a Bioenergy Action Plan in 2023[35] to take account of decisions that are devolved to the Scottish Government.

    Projections of bioenergy demand across sectors in Scotland were carried out in 2022 by Ricardo on behalf of CXC[36]. In agriculture, the demand for bioenergy is expected to grow from 0.8 TWh in 2020 to 3.3 TWh by 2030 predominantly due to an increased demand for biomethane from AD. For modelling purposes however, the report assumes that by 2045 agricultural bioenergy demand will drop to zero since electricity generation via Bioenergy with Carbon Capture and Storage (BECCS) as a negative emissions technology is expected to dominate bioenergy demand in Scotland.

    Heat Pumps (Air-Source and Ground-Source)

    Heat pumps are an alternative low carbon heating solution relevant to agriculture in Scotland. Energy is extracted from the air, ground or water and delivered to a building as heat using electricity to run its components, primarily a compressor. Heat pumps are more efficient than combustion boilers or electric boilers. However, the efficiency can vary across the heating season and across different building use cases. In Scotland, the Heat in Buildings Strategy sets out a vision to improve heat in buildings and various actions being deployed in the building sector to reduce GHG emissions and support economic opportunities, as well as alleviate fuel poverty[37].

    There is an absence of literature discussing the potential of heat pumps in the Scottish agricultural sector. However, it is well-documented from UK case studies that heat pumps can be used to serve agricultural processes. For example, a 6.2 MW Ground-Source Heat Pump (GSHP) was installed in 2021 near Berwick-upon-Tweed which performs simultaneous heating and cooling to dry and condition grain respectively[38]. Other use cases include chilling milk at dairy farms, chilling potatoes in cold stores and heating broiler sheds. In the latter, circulation pumps can remove excess heat from the sheds and return to the ground for future heat cycles. GSHPs make sense for farms due to land availability and once the plant has been installed pastureland can recover quickly. A common theme in literature indicates that heat pumps are most financially attractive where there is both a heating a cooling demand due to the heat recovery that exists between heating and cooling loads. Heat pumps offers carbon savings that are not possible via other technologies such as direct electrification since for one unit of electricity consumed by the heat pump, two to four units of heat are supplied[39]. While the case studies highlighted here focus mainly on GSHPs, air source heat pumps (ASHP) are also applicable in an agricultural context.

    Hydropower

    Hydropower, or hydroelectric power, generates electricity using large volumes of fresh water through the alteration of river watercourses and storage in reservoirs and lochs. It is the controlled release of water through turbines that converts flowing water into electrical energy (MacLeod et al., 2006). Part of this technology includes micro-hydropower systems. These are small to medium sized installations which make use of rivers and fast flowing streams. Installations such as these are more site-specific (from farm to farm or community to community) and can be prone to seasonal variation, for example flooding and drying (Sample et al., 2015).

    Hydropower forms an important part of Scotland’s renewable energy supply. As of 2022, the total output was estimated to be 4,866 GWh, accounting for a total of 14% of all renewable energy output in Scotland, with further installations currently under consideration[40]. Existing hydropower sites in Scotland are categorised as either “run-of-river” (RoR) sites and require little to no water storage infrastructure, alternatively “impoundment” schemes involve the construction of large dams.

    Hydropower is the second largest onshore renewable technology in terms of capacity and electricity energy generation despite the substantial growth and development of other technologies in recent years[41]. There is potential for new, large-scale hydro with a total of 19MW currently in the pipeline[42]. In terms of Scotland’s agriculture sector, there is further potential for the development of micro-hydropower installations. Micro-hydropower plants are dispersed throughout Scotland as part of on-farm renewable energy projects. Examples of this include: a 20kW hydro system installed in Dumfries and Galloway to power various farm buildings, one of three hydro schemes currently on the farm; and a 190kW system implemented on a 566.5-acre sheep (and fish) farm[43], [44].

    Additional considerations for this technology include the effects of seasonal change as well as climate change and the potential increase in competition for future water resources. Increased demand for irrigation in agriculture during the dry summer months may result in reduced energy generation. Meanwhile, further intensification of the hydrological cycle due to climate change leads to a change in both size and seasonality of water flows (Sample et al., 2015).

    Hydrogen

    There is little literature discussing the role of hydrogen to decarbonise agriculture in Scotland. Scotland has committed to the ambition of at least 5GW installed renewable and low carbon hydrogen production capacity by 2030 and 25GW by 2045 via the Hydrogen Action Plan[45]. The Plan further denotes that hydrogen has a role to play in rural and island communities as well as in cities and industrial clusters. Hydrogen is most likely to be used in sectors where there are few other decarbonisation options; most notably in heavy duty transport or non-road mobile machinery (NRMM), as well as high temperature process industries. In agriculture, there will be vehicles that may benefit from either hydrogen combustion propulsion because they are too big to electrify (such as combine harvesters), or, hydrogen can be used with fuel cells and act as range extenders to provide an extra boost to EVs during times such as harvest.

    Farms in Scotland that have on-site renewable power generation assets such as wind or solar that experience high levels of curtailment could be in a position to produce hydrogen on-site and either use the hydrogen on-site or export to a third party such as an HGV fleet. At present, there are no examples of this in Scotland, though the HydroGlen project is conducting a feasibility study into green hydrogen for transport applications in an agricultural setting[46].

    Potential benefits from an emerging second-hand market in renewables

    The literature review found little information on the current potential to benefit from an emerging second hand market in renewables and related components. It is evident that there is an existing second-hand market for refurnished/remanufactured wind turbines and parts for wind and solar in Scotland which provides an opportunity for farmers to uptake these technologies at a lower cost. The search found a number of commercial companies are acting in this area and can help with the entire process, from early project development and feasibility studies, through to installation, grid connection, commissioning, through to operation and maintenance. However, there may be limitations on the reach of these companies, it is informally reported that access to individuals with the skills to support maintenance can be a significant barrier for farmers in Scotland. The skills gap if addressed may also provide a local employment opportunity.

    Land use implications for low carbon energy production

    The REA identified several topics regarding land use where differing views are presented and subject to active debate.

    Competing demands for land

    In Scotland (and globally), there are concerns regarding competing demands for land in the name of food or energy security[47]. This discussion has gained traction in recent years. Namely, the energy and agricultural regimes compete for use of agricultural land, both functionally (food vs. fuel) and in terms of control (farmer vs. corporations). This debate is typically centred around bioenergy crop production, but also includes the installation of solar panels, large wind turbines, processing plants, or any large installation that may take agricultural land out of production.

    Scotland has the potential for bioenergy to produce approximately 13 TWh per year[48], which could make a notable contribution to Scotland’s renewable energy needs and targets. Some (3 TWh per annum by 2045) of this contribution is assumed to come from short rotation coppice (SRC) energy crops, such as willow. While SRC energy crops may aid in meeting short‐term needs over the transition towards low carbon energy supply there is debate over whether using land for bioenergy demand is appropriate when the same land can be used for food production[49]. It should be noted that energy crops may not need to be grown on the most productive land. There is also a debate as to whether land that cannot be used for agriculture, such as severely degraded or and marginal lands may be more appropriate for solar PV farms, for example (Child et al., 2019).

    Changing land uses from food production to fuel production in Scotland will have direct impacts on biodiversity, wildlife, and landscape connectivity – either positive or negative. It is important to have the appropriate bioenergy crops in the right place to support the protection of biodiversity and ecosystems and preventing unnecessary ecosystem damage[50]. The type of land use change will affect the severity and extent of impacts. Aside from these more visible impacts, there are impacts related to opportunity costs for the agricultural sector itself, and from ecosystem services and carbon sequestration. There are significant opportunity costs from taking agriculturally productive land out of production for the use of renewable energy installations or bioenergy crop production.

    Competing demands for land extend beyond fuel production. While out of scope of this report, it is important to consider other demands for land in Scotland that will continue to impact both food and fuel production alike – simultaneously or individually. These may include:

    • Housing and urban developments.
    • Forestry areas to meet Scotland’s afforestation targets.
    • Peatland areas protected for carbon sequestration potential and/or private upland areas under moorland management; and
    • Protected areas and areas of outstanding natural beauty and heritage.

    Farm location and electricity distribution network accessibility

    A study exploring the possibilities for farmers in Wales to diversify into sustainable energy found that an isolated farm location poses a threat to the viability of a farm to generate income from renewables. In addition to this, niche farm locations, such as farms located in national parks or scenic areas, can be accompanied with planning restrictions and regulations which hinders the viability and accessibility of introducing renewable energy technology on farm as technological developments are less likely to be granted (McKenna et al., 2022). Electricity distribution network capacity and accessibility has the potential to limit the farmers ability to export to the network. This was reiterated by a respondent in the study who confirmed there was “stiff opposition to wind turbines and solar panels and the connection to the grid was insufficient” (Morris and Bowen 2020).

    A study researching the status of the energy systems of Scottish islands found that across all islands there is a restriction to connecting additional renewable generation and a recognition that supply and demand of power is crucial. Due to the remote locations these islands are often at the end of the network, therefore considerable investment if required to increase export capacity. To manage this, the need for any additional energy supply, must be justified with evidence of additional demand. This reduces the feasibility of technology in the remote areas of Scotland including the islands.[51] However, the situation is improving, Shetland will have a new transmission connection live in 2024 and Orkney and the Western Isles have had their new connection approved.

    In the ‘Renewable energy in Scotland Fourth Report of Session 2021-22’ report, the Head of System Planning, Scottish and Southern Electricity Networks noted: “until we get a certain level of certainty about projects going ahead, we are not able to make a robust investment case in the electricity distribution network”. Whereas, Chief Executive Officer, EDF Renewables commented that there should be better preparation for investment in the electricity distribution network: “More can be done to anticipate the investment needed to support renewable projects”. The seriousness of electricity distribution network accessibility was highlighted when the Scottish Affairs Committee called for OFGEM to consider the long-term impacts on net zero targets by completing a review of the grid in Scotland as a matter of urgency and to prioritise reinforcement of the grid where there is potential for a high renewable energy yield.[52]

    In response to the recent changes in power generation and with an increasing number of more small-scale producers generating their own power, the Office of Gas and Electricity Markets (Ofgem) introduced the Access and Forward-Looking Charges Significant Code Review (Access SCR) in 2018.[53]

    The Access SCR aims to promote the efficient and flexible use of the electricity network meeting both the users’ needs and allowing new, low carbon technologies to benefit consumers while also avoiding unnecessary high energy costs. The SCR primarily sets out how different parties access the grid network as well as the related costs involved.

    In 2023 a final decision was published providing changes that reduce upfront costs for producers when connecting to the distribution network, strengthening existing protections for energy consumers while also enhancing the choice of “access rights” each customer has to the network. Such reforms will make future grid connections more accessible and feasible for energy generators, which includes farmers.

    Tenure

    Tenure directly impacts on the feasibility of introducing non-carbon technology on farm. It is an important factor in farm diversification as any restrictions set out in land/tenancy agreements will limit possibilities. In addition to this, long term investments are not deemed feasible for short term tenancies (Sutherland et al., 2016). Similarly, issues relating to crofting law and developments on crofting land poses as an accessibility issue for crofters. Statutory provisions can be complex and, in terms of developing renewable projects, more work may be required to comply with crofting legislation[54].

    Land availability

    Land availability will impact the viability of Scotland being able to decarbonise the agricultural sector. Renewable energy projects tend to require large amounts of space to sufficiently capture enough energy to be viable (Bergmann et al., 2006). Moreover, the viability of introducing technology on farm must consider land availability and suitability. Shepherd et al., 2021 found an initial 4.38M ha of land was available in Scotland for onshore wind turbine. This 4.38M ha refers to area which has been identified as well suited for development as it is already well provisioned with high voltage power infrastructure and, in general, encompasses Scotland’s existing turbine sites. However, when land suitability (e.g., ‘arable and horticulture’ and ‘rough grassland’) and soil types were considered the available area reduced from 4.38 million ha to 3.83 million ha.

    Other barriers identified in the literature

    Cost and investment

    Whilst investing in renewable energy is well known to reduce operating costs on farm (Morris and Bowen 2020), the initial cost of the investment required for some technologies can be a barrier to uptake. This barrier extends to other forms of low carbon technology such as RAS (robotics & autonomous systems) as UK and Scottish studies, state that RAS is accompanied with high investment costs which are likely to be prohibitive to smaller farms (Herr et al., 2020 ; Reid and Wainwright., 2018).

    Although renewable energy has been produced on farms for a long time, economics are still considered an issue (Spackman, P., 2016). Financial consideration must be given beyond the initial investment of technology, for example farmers may be subject to building, infrastructure, planning and consultancy costs as well as labour, maintenance, and other recurring costs. (MacLeod at al., 2016). Nonetheless, in a case study looking at a biomass grain dryer, a Scottish farmer stated, “We’re saving 6p/kWh, getting RHI payments amounting to almost £8,500 a year and expect a payback in two to three years.”[55] This positive financial outlook is reiterated by papers such as Rahman et al., 2022 who details, whilst still high, the cost of wind turbines are reducing as well as articles stating technology, such as solar panels, are continuing to fall in price in Scotland[56]. Nevertheless, costs remain an issue in terms of accessibility and viability as uptake of technology is negatively affected by high capital costs and/or lack of financial capital to cover long term investments and high financial risk (Acosta-Silva et al., 2019; Baker et al., 2022; Morris and Bowen., 2020).

    Availability of cash to invest upfront is essential to establish new renewable and bioenergy projects. As the RHI ended in the spring of 2022, options to displace current energy costs are critical as without this, margins can be unattractive for investing. There is currently much uncertainty for farmers as withdrawal from the European Union, will mean a change in agricultural policy and support structures. This uncertainty may result in a reluctance to make investments at the current time, though equally there may be others who see renewable energy as a diversification opportunity giving longer term income benefits[57].

    Public perception

    Public perception towards the introduction of renewable energy on farm is a currently under debate. Some of the key drivers for introducing circular economy into the agri-food supply chain include environmental benefits (67%), policy and economy[58] (47%) and financial and economic benefits (43%) (Mehmood et al., 2021).

    It is recognised throughout literature that introducing renewable energy on farm improves many aspects; the business’s carbon footprint, self-sufficiency, financial savings, sales of generated power and enhances socio technical values such as brand image (Jones et al., 2020; Spackman, 2014; Yousefzadeh et al., 2023) all of which drives a positive public opinion.

    Many studies investigate the drivers and barriers influencing farmers’ adoption of renewable energy technologies. Studies found that younger farmers, and farmers that had progressed further in education had a more positive outlook on renewable energy and are therefore more likely to adopt these technologies (Ge et al., 2017). Nonetheless, some farmers have expressed a negative identity-based paradigm, considering the change of land use away from crop production to incorporate renewable energy e.g., solar panels to no longer being farming (Moore et al., 2022).

    Public opinion varies and can negatively impact upon uptake of non-carbon technology on farm. Research shows that the most supported renewable energy source is solar, whilst, onshore wind farms are favoured by a smaller majority than most other forms of renewable energy.[59] Concerns regarding wind power largely focus on the visual impact on a landscape, production of ‘unwanted’ noise (Rahman et al., 2022) and environmental impact in terms of land use change and degradation of peatland for turbine and road access construction (Shepherd, A. et al., 2021). Moreover, in the 2010s, whilst there was an increase in planning permission applications to introduce wind turbines in Aberdeenshire, it was public concern that led to a high proportion of these turbine applications being rejected. (Sutherland et al., 2015).

    Complex renewable technology such as technology related to biomass has been found to be associated with uncertainty, whereas negative public opinion relating to other technologies such as solar focused on cost and feasibility (Demski, 2011). On the positive side, research shows that those living in the Highlands and Islands and those living in closer proximity to renewable energy installations have a more favourable attitude towards these developments.

    On farm renewable potential to meet energy needs

    Within Scotland, there is great potential for farm businesses increase uptake of low carbon technologies. This section provides analyses of the strengths and weaknesses of these technologies, factors supporting or hindering uptake, and a discussion on how excess renewable energy production on farm can be marketed to other sectors in Scotland.

    SWOT analysis of on farm energy generation

    The SWOT analysis assessed the current potential for on-farm energy generation in Scotland, looking at strengths, weaknesses, opportunities, and threats (SWOT) to provide a simplified picture and more clarity of where action is needed. These technologies are applicable across different agricultural sectors and contexts, although some are more suited to specific sectoral needs and requirements. For example, hydrogen currently has explicit uses; being a nascent technology for farming, its current strengths are contained to levels of innovation and specific applicability within the sector. There are extended SWOT tables of individual technologies with further detail in Appendix C. The SWOT tables below are grouped according to the following categorisations:

    • Solar PV, onshore wind, and hydropower are energy generation opportunities on farm, which support current and future energy demand, and provide alternative income streams;
    • Electric vehicles (EVs) and heat pumps provide alternatives to fossil fuels via electrification;
    • Hydrogen is a future fuel as it is a nascent technology for farming with specific applications; and
    • Bioenergy covers multiple different solutions, from biomethane to wood chip; these all have specific land use implications.

    The SWOT analysis shows the interactions between the technologies identified here. A weakness seen in most technologies was the high capital expenditure (CAPEX), despite many having low operating expenditure (OPEX). Farmers may struggle to pay for high initial investment costs without support, and the land use or landscape implications of certain technologies is often a dissuading factor. However, government support schemes provide an opportunity to promote uptake across the sector.

    There was little evidence to show that specific technologies did not have a role, although hydropower has less potential to others due to its significant impact on land, rivers, and aquatic ecology as well as location requirements, so its application is very context specific.

    There are numerous opportunities to expanding on existing technologies with novel applications, such as hydrogen powered vehicles, and hybrid wind-solar systems to enhance reliability.

    Table 7: SWOT table covering the themes presented across solar PV, onshore wind, and hydropower generation technologies as alternative electricity sources. The strengths, weaknesses, opportunities, and threats are applicable to all technologies noted in the table heading, unless stated otherwise.

    • Potential threat to wildlife and local ecology, especially during installation but also potentially during operation
    • Highly visible
    • Installations situated in upland peatland areas damage peat during construction, and tracks over moorland damage flora.
    • Depending on the unit size there are differences in suitability for location. Altitude, latitude, and aspect are important to consider.
    • There can be opportunity costs from taking agriculturally productive land out of production for the use of these installations (the loss of income from agricultural production where installations reduction opportunity for this by taking up space).

    Opportunities

    Threats

    • Long term income stream from electricity distribution network exports. Helps to manage costs, reduces imports and reduces risk of fluctuating costs.
    • High potential in the specific sectors (e.g., solar for poultry, wind for dairy)
    • Opportunity for marginal land to be used.
    • Lack of planning issues for smaller scale installations creates enabling environment for potential uptake.
    • Opportunity for pastoral farming (mainly grazing) to happen in the same area as the installation.
    • Opportunity for low-cost batteries charging for small agricultural applications on site, such as those for pumping, electric fencing, lighting, small electronic systems.
    • Ideal for off-grid locations (wind, hydro)
    • Existing second-hand market for parts (solar, wind) in Scotland provides room for low-cost uptake.
    • Potential for knowledge sharing and adapting successful projects to local purposes provides a resource with significant potential.
    • There is considerable scope in Scotland for the development of further small-to-medium sized installations.
    • Can offer opportunities for diversification and employment in rural communities
    • Future climatic and environmental changes may threaten the opportunity for uptake, as energy generation could be affected.
    • Electricity distribution network access is an issue, especially for larger commercial projects. There is a high cost of making efficient connections to the existing electricity distribution network.
    • Social acceptance
    • Land ownership and length of tenure can impact uptake.
    • There is a need for permitting or licensing through local authority planning which can affect uptake.
    • Scotland has many zones of natural heritage and designated sites, which can affect planning permission acceptance.
    • Negative public opinion of installations due to visibility
    • UK government policy and support is inconsistent, which makes investment a risk.
    • Compliance with crofting legislation – projects on croft land or common grazing require further action and planning considerations.
    • It is difficult to find someone to maintain second hand market parts and insurance is not always available for second hand installations However, this could present an opportunity for upskilling.

    • Inability to currently support all necessary farming activities.
    • Sites may require an electricity network capacity upgrade (heat pumps) or charging infrastructure (EVs)
    • This may also lead to trade-offs including longer working days for farmers, reduced total field time, or having to recharge multiple times a day (EVs)

    Opportunities

    Threats

    • For sites with renewable power generation, heat pumps and EVs can utilise this to reduce operating costs and carbon footprint.
    • There are many relevant applications in agriculture for these technologies.
    • Good opportunities for use in specific agriculture sectors (e.g., heat pumps for dairy, EVs for graziers or arable farming)
    • High Temperature Heat Pumps (HTHPs) are beginning to become available.

     

    • Payback period depends on relative gas/oil and electricity prices.
    • Most heat pumps provide temperatures of up to 50-60°C therefore for space heating application for domestic applications, user needs well insulated property or must increase radiator area for greatest efficiency. Similarly, EVs battery performance is significantly impacted by cooler operating temperatures.

    Table 9: Analysis of hydrogen energy generation and use in agriculture. The strengths, weaknesses, opportunities and threats are applicable to all technologies noted in the table heading, unless stated otherwise in the table.

    Strengths

    Weaknesses

    • Hydrogen is a non-toxic fuel.
    • Hydrogen vehicles does not require long charging durations, unlike EVs.
    • A hydrogen internal combustion engine will not be much more expensive than diesel versions equivalent by 2030.
    • Maintenance and longevity: for hybrid systems, diesel particulate filters will need to be replaced less frequently on modern tractors and oil change hours can also be extended.
    • Hydrogen is a versatile energy carrier and storage medium.
    • Green hydrogen can be produced during off-peak periods or times when there is excess renewable electricity, instead of curtailing the excess energy.
    • Hydrogen can be stored for a long time.
    • There is currently no established supply chain.
    • The high energy requirement of hydrogen production
    • Challenges arise in trying to store and contain it, as hydrogen can leak out of ordinary metal storage containers.
    • High cost/initial investment, particularly in terms of agriculture which is a highly distributed sector where demand for hydrogen is low compared to other sectors.
    • Green hydrogen is currently challenging to obtain and expensive, with costs that will be passed to the farmer.
    • Storage issues – as a highly-combustible fuel, hydrogen could be dangerous when storing on site, and there are requirements for storage and use under UK-wide Health and Safety Executive guidelines.
    • Low volumetric energy density

    Opportunities

    Threats

    • Hydrogen powered machinery offers similar performance as current internal combustion engine (ICE) mobile machinery.
    • There is an opportunity for cost-effective energy-production processes where agricultural wastes and various other biomasses can be recycled to produce hydrogen economically.
    • Can be used in farm machinery to replace ICEs and cut emissions, without the complications that come with heavy EV batteries.
    • Mechanically, the technology for running hydrogen vehicles and machinery already exists.
    • As a growing proportion of Scotland’s energy production comes from renewable sources located in rural areas, there is the potential for partially decentralised hydrogen production to provide fuel to the agricultural sector.
    • Hydrogen and renewable hybrid systems on farm have the potential to create local renewable energy communities, providing energy to surrounding buildings.
    • There are already capital incentives for hydrogen, such as the UK Government’s Net Zero Hydrogen Fund[60] and up to 100m for renewable hydrogen from the Scottish Government‘s Emerging Energy Technologies Fund, as set out in the Scottish Hydrogen Action Plan and Route Map to 2030 and 2045[61]
    • The major problem in utilization of hydrogen gas as a fuel is its unavailability in nature and the need for inexpensive production, storage and transportation methods.
    • Infrastructure in the UK is still lacking.
    • Hydrogen in a rural context is a nascent area and new developments and innovations are expected, but currently the evidence base for applications of hydrogen are limited to pilot projects which could scale, such as HydroGlen at Glensaugh Farm, which is run by the James Hutton Institute and received Scottish Government funding[62].
    • NOx emissions are still present from combustion but can be managed to low levels via lean combustion or flue gas recycling.
    • Profit margins are fine in the agricultural sector and red diesel (untaxed) is currently cheaper than hydrogen.

    Table 10: Analysis of bioenergy generation and use in agriculture.

    Strengths

    Weaknesses

    Various types of bioenergy can be used to replace fossil fuels.

    Solid Biomass

    • Well-developed technology
    • Woody biomass (e.g., Short Rotation Coppice) contributes greater soil carbon sequestration during growth in comparison to cultivated crops in the same area.
    • Benefits of SRC, miscanthus & forestry – reduced erosion and improved flood reduction
    • Marginal land can be used for SRC.

    AD/Biogas/Biomethane

    • Makes use of raw materials and by-products straight from the farm/onsite, manages waste from livestock farming, helping reduce the need for storage, maintain environmental safety, reduces GHG emissions and stimulating the development of local economies.
    • Waste to biogas using AD is considered most environmentally friendly due to minimum carbon leakage and positive waste resource recycling impact.
    • Safe treatment and disposal of agricultural waste
    • By-product from AD is digestate which can be re-applied to soils as an organic fertiliser.
    • Use of slurry for AD reduces methane emissions that would arrive from slurry storage.

    Liquid biofuels e.g., biodiesel and bioethanol

    • Ethanol has a competitive price in the market.
    • Non-toxic, biodegradable, free of sulphur
    • Works in any diesel engine with few or no modifications
    • Biodiesel provides mobile machinery users with an alternative fuel that will allow ‘business as usual’ operation. Each engine model will have stipulations for the maximum percentage of liquid biofuels that can used without modification to the engine. Some engines can operate on 100% liquid biofuels by volume.

    Solid Biomass

    • High maintenance (OPEX) of biomass boilers, especially in comparison to other options, and high CAPEX.
    • High competition in the wood fuel market
    • Forestry biomass can be of unreliable quality and supply is not always guaranteed.
    • Air quality can be a concern for farms nearby urban areas.

    AD/Biogas/Biomethane

    • Gate fees remain a significant deterrent for farmers (who can spread untreated livestock waste for free)
    • High initial investment
    • Upgrading of biogas (50–65% CH4) to biomethane (>90% CH4) is costly and energy demanding.
    • AD will often not be suitable for small-scale farms.
    • Lignocellulosic rich waste streams require pre-treatment before AD to improve methane yield.

    Liquid biofuels e.g., biodiesel and bioethanol

    • Dedicated land for growing crops for biofuels competes with human/animal feed production.
    • Current production of perennial energy crops in Scotland is limited.
    • Some suboptimal use – use for financial incentive but not always the best technology for specific uses. Previous incentive schemes encourage uptake.
    • Producing biofuels is not energy-efficient (Biofuel)
    • GHG reduction is modest compared to other measures (Biofuel)
    • High costs and complexity of the logistics and supply chain management
    • Securing feedstock can be challenging (AD)
    • Lack of suitability of technologies to some buildings (e.g., Biomass boiler)
    • Biodiesel is water intolerant and thickens at temperatures below 0 degrees Celsius, therefore, shelf life is limited and is more complex to store than fossil diesel.
    • Few commercially available biomass CHP systems available on the market other than those based on anaerobic digestion (biomass CHP)

    Opportunities

    Threats

    Solid Biomass

    • The use of forest and agricultural residues does not compete with crop production.
    • Pyrolysis and gasification of solid biomass produces a by-product known as biochar which can be used as a soil improver, animal feed supplement and for water treatment.
    • Ash from combustion can be used as a fertiliser.

    AD/Biogas/Biomethane

    • Biogas can be used like natural gas to directly heat facilities on site and produce electricity via Combined Heat and Power (CHP)
    • Cellulosic feedstocks grow well on marginal lands (cellulosic biomass crop) (biofuel)
    • Biogas and electricity production is feasible for all types of dairy farms.
    • Price support in the past has led to exponential increases in uptake; future price support schemes could do the same (Biogas)
    • There are opportunities for local AD plants and agricultural waste biomass plants on islands in Scotland, reducing the communities’ carbon footprint due to removing the need to ship waste to the Shetland Island for disposal (case study)
    • Supply of bioresources is often not sustainable – stringent sustainability criterion needs to be imposed.
    • Uncertain farm-scale profitability of biogas
    • Taking fields out of food production (biogas, biofuel, and biomass) creates conflict between food and fuel production. However, the RTFO[63] has a ‘crop-cap’ to mediate this.
    • Changing energy policy complicates the financial appraisal of AD projects.
    • Agricultural reuse of AD as potential renewable fertiliser can pose some hygienic and environmental hazards, and storage issues (there is a limitation of land disposal imposed by the Nitrates Council Directive)
    • AD plants which use distillery co-products, such as draff, pot ale and dark drains, as a feedstock have constrained supply and increased their prices. This had had a knock-on effect for farmers who purchase these products as animal feed.
    • If there were to be widespread adoption of biomethane as an alternative fuel for agricultural mobile machinery in Scotland, there would likely be large pressures on biomethane production and availability.
    • Concerns with the effects of potential ‘methane slips’ in biomethane machinery

    PESTLE analysis of potential to decarbonise on farm energy use.

    Renewable energy technologies are subject to a range of enabling and preventative factors. A political, economic, social, technical, legal and environmental (PESTLE) analysis was therefore undertaken to assess the potential to support on-farm renewable energy generation and the decarbonisation of agricultural energy use in Scotland. This assessment was produced following the SWOT analysis to incorporate the strengths and opportunities of each renewable energy technology (and more generally) identified in the SWOT.

    Table 11: Political analysis of enabling and preventative factors for on-farm low-carbon energy generation and agricultural energy use decarbonisation

    Enabling factors

    Preventative factors

    • Government policy (especially in the past) that incentivise renewable energy uptake in Scotland can bring down costs and increase uptake.
    • Government policy levers that are pushing businesses, including farm businesses, to decarbonise, either directly or by driving businesses such as supermarkets to pass on obligations to farms.
    • The Scottish Government’s Community and Renewable Energy Scheme (CARES) programme supports communities to engage with and benefit from the energy transition to net zero emissions. Local communities can access funding to install renewable technologies.
    • Smart Export Guarantee scheme and others provide investment in small-scale renewable projects up to 5MW capacity.
    • Political will for decarbonisation (e.g., 2045 net zero targets for Scottish Agriculture)
    • Conflicting policies and targets can impact uptake (e.g., afforestation targets can indirectly divert water away from hydropower installations)
    • Lack of regulation over nascent technologies (e.g., hydrogen, robotics)

    Table 12: Economic analysis of enabling and preventative factors for on-farm low-carbon energy generation and agricultural energy use decarbonisation

    Enabling factors

    Preventative factors

    • Energy price rises driving interest/change.
    • Market pressures to decarbonise – supermarket requirements driving change down the value chain.
    • A general desire to diversify farm income.
    • The agricultural sector with access to such large areas of land has lots of scope for potential uptake of renewable energy.
    • Larger scale installations can offer opportunities for employment in rural communities.
    • Capital grants or support schemes can help farmers shoulder on-farm costs and encourage uptake.
    • Purchase of equipment for collective use within communities
    • Economic viability of farmers: future uncertainty heightened by agricultural transition and highlighted changes in support payments since Brexit.
    • High initial capital expenditure requirements for most renewable technology installations.
    • Lack of access to (and awareness of) capital and grants and uncertainty in available capital to invest.
    • Farms and crofts are generally small businesses, and therefore there is a small margin of error for energy investments on farm.
    • Competition increasing land prices- bioenergy crops/corporate and private interest in land for carbon and nature-related offsetting /food security.
    • There is a conflict between agriculture and tourism businesses in islands and other rural areas, which can lower availability of specific renewable elements (e.g., biomass)

    Table 13: Social analysis of enabling and preventative factors for on-farm low-carbon energy generation and agricultural energy use decarbonisation

    Enabling factors

    Preventative factors

    • Rural and local energy communities can work together to support and create micro-grids and install renewable technologies through community action and crowdfunding, enabling access to renewable energy in remote locations.
    • Strong peer-to-peer learning between farmers, knowledge sharing, and community support for education
    • Legacy on farm – longer term view to support future generations with more renewable energy generation (even in some tenancies)
    • Generally widespread public support for renewable energy installations
    • Grassroots, community led support to solve issues on farm (e.g., supplier or mechanic recommended between farming circles, developing trust)
    • The energy and agricultural regimes compete for use of agricultural land, both functionally (food vs. fuel) and in terms of control (farmer vs. corporations)
    • Issues around access to equity, especially for farmers in lower socio-economic bands
    • Potential at govt level to say that things are coming rather than farms fighting the battle – collective top-down support.
    • Contract/short term tenant farms less likely to be able to implement renewable technologies due to contract and communication difficulty with landlords.
    • Land ownership – corporations/wealthy people buying up land for carbon sequestration and ‘CSR’ purposes.
    • Competing land pressures in central Scotland – e.g., housing; other pressures
    • Changing uses of land not always in favour of tenant farmers
    • Some local objections to installations, such as biogas.

    Table 14: Technical analysis of enabling and preventative factors for on-farm low-carbon energy generation and agricultural energy use decarbonisation

    Enabling factors

    Preventative factors

    • Many renewable energy technologies are already widely used across Scotland.
    • Established low carbon heat sources to displace fossil fuels.
    • Renewable electricity generation can reduce electricity costs and support electrification of polluting energy sources.
    • A range of low and zero emission transportation technologies are available (but not those for majority of agriculture uses).
    • Emerging vehicle types (hydrogen, electric) are more widely available. Applicability and impact not yet clear
    • Combining multiple technologies can unlock additional benefits, manage operating costs, and reduce impact on the grid.
    • Electrification of energy use often improves energy efficiency
    • Depending on the location within the electricity distribution network, access can be a problem, especially in rural and remote areas, where most farms are located.
    • Electricity network constraints means that there is a limit to scalability of renewable generation or electrification of energy use.
    • New or rapidly evolving technology (hydrogen, robotics) create an investment risk, due to deployment issues or a risk of obsolescence.
    • People are cautious based on experiences of ‘cowboy builders’ – those with no proper training or official qualifications that do work to a low standard.
    • On farms, technologies are often added one by one, so there is less opportunity to manage energy load. This can mean more grid impact initially than would be the case in long term.

    Table 15: Legal analysis of enabling and preventative factors for on-farm low-carbon energy generation and agricultural energy use decarbonisation

    Enabling factors

    Preventative factors

    • Small scale installations and microgrids can benefit from permitted development rights where planning permission can be granted without the need for local planning authority applications (although a permitted development status still requires an application to be made)
    • Environmental permitting – driving change for reduction of emissions onsite.
    • While important for other reasons, planning requirements or restrictions in certain areas (e.g., designated sites, AONBs) can hamper the uptake of renewable technologies (especially wind turbines and solar panels).
    • Licenses for water abstraction (e.g., for hydropower) can hamper uptake.
    • Land ownership and tenancies can cause disputes over implementing renewable technology, leading to slow uptake.
    • General binding rules – restrictions on water use (e.g., AD)
    • Cleaner air for Scotland strategy – combustion technology (e.g., bioenergy) barrier
    • Inheritance tax considerations for changes in agricultural land use for some renewable energy production types.

    Table 16: Environmental analysis of enabling and preventative factors for on-farm low-carbon energy generation and agricultural energy use decarbonisation

    Enabling factors

    Preventative factors

    • Changing climatic and environmental conditions due to climate change can positively affect the capacity renewable energy techs (e.g., increased sun exposure from hotter and drier summers)
    • Many farms have the resources (e.g., agricultural residue) or space (e.g., marginal land, existing barn and building roofs for solar panels) available to support biomass energy production and the installation of other technologies.
    • Positive environmental and biodiversity benefits from bioenergy crops in comparison to managed grasslands or arable crops (relative to the ecosystem)
    • There are competing land pressures in central Scotland (e.g., housing/ afforestation). Additionally, renewable energy projects normally require large amounts of space to capture the energy in wind, water, or solar radiation in sufficient quantity to be commercially viable.
    • Changing climatic and environmental conditions due to climate change can negatively affect the capacity renewable energy techs by increasing uncertainty in weather conditions.
    • There is a need to identify the negative environmental impacts when installing technologies (e.g., installing wind turbines on peat land)
    • Intensification of land for biomass production previously not used for cropping (e.g., land use change from grasslands to bioenergy crops)
    • Negative environmental and biodiversity implications from the growth of bioenergy crops (relative to the ecosystem)

    Analysis of wider decarbonisation for the energy system

    While the decarbonisation of energy generation can reduce carbon dioxide emissions on farm, there is great potential for agriculture-based energy generation to support the decarbonisation of the wider energy system in Scotland. Farms which generate renewable energy can use it to meet their own energy needs, displace fossil fuels, and reduce their costs and carbon footprint. Adding energy storage and new technologies to use the energy they generate gives farmers more control over energy costs and essentially forms an on-farm energy system. These energy systems can provide wider benefits such as:

    • Providing renewable energy to the electricity distribution network and reducing reliance on fossil fuels or on importing energy from elsewhere;
    • Reducing the need for electricity distribution network upgrades by generating, storing and using energy at farm level as opposed to relying on the electricity distribution network to supply it. This is particularly important for high power demands such as rapid charging of EVs, HGVs or mobile machinery.
    • Using these systems to meet some high-power energy demands such as EV charging for farm workers, suppliers or local communities. This would reduce the reliance on the electricity distribution network to meet these demands in rural areas and could reduce costs.
    • In the future, it would be technically feasible for agriculture sites with suitable systems and access to host EV charging for use by third parties, possibly including future charging of HGVs.

    The benefits are particularly pronounced in areas where the electricity network is either highly constrained or for farms not connected to the electricity distribution network, such as some islands or remote communities where community access to energy relies on microgrids. The agriculture sector is a large part of the local economy, so widespread on farm uptake of low carbon energy systems could have a significant effect.

    Electricity and gas grid exports

    Farms which generate, store, and consume energy may be able to import and store energy at times of low demand or export energy at times of high consumption. There will be limitations on the capacity of individual network connections, and the potential benefit to distribution networks will vary. However, sites which generate, store, and consume electricity could have a role in balancing distribution networks by providing flexibility. The nature of renewable energy means that production is not always consistent with demand, especially for those technologies that rely on natural resources such as wind and solar energy. Onshore wind is the largest single provider of renewable electricity in Scotland, and Scotland maintains the largest proportion of onshore turbines in the UK, with 8.8GW of onshore wind capacity that accounts for over 60% of the UK’s total onshore wind capacity as of 2021[64]. Wind production in Scotland on farms, particularly in areas of high altitude and latitude, provides excellent opportunities to deliver excess energy to the electricity distribution network whilst also meeting on farm energy needs.

    Additionally, in the UK, the Smart Export Guarantee (SEG) enables an additional income stream for farmers, while supporting electricity distribution network decarbonisation. If a farm has a solar PV system and generates more power than is required onsite, the surplus will be put onto the electricity distribution network. Under the SEG, electricity suppliers offer payment for each unit of power that is exported to the electricity distribution network. It should be noted that some energy vectors are easier to sell to the gas and electricity distribution network operator; solar electricity is noted as being easier to produce and sell to the electricity distribution network compared to biomethane to the gas grid as additional technology is required to upgrade the biogas to biomethane which must meet stringent quality and calorific value requirements which are imposed by the gas distribution network operator (Rikkonen et al., 2019). Obton (2021) notes that an area of 100-acre covered in solar panels can generate 40 MW of electricity, which is enough to provide power to 10,000 UK households.

    Further, newer fuels such as hydrogen have the potential to contribute to electricity distribution network exports and support national demand. Through electrolysis, green hydrogen can be produced during off-peak periods or times when there is excess renewable electricity, instead of curtailing it as it is commonly done. An important consideration is the network connection, some parts of the grid are constrained, depending on the location, and it can be more difficult to get a grid connection in these places. This is exacerbated by the rural nature of some farms in Scotland. There may be potential opportunity for farmers to support wider electricity distribution network decarbonisation through generating and supplying hydrogen to local authorities, or companies running fleets of fuel-cell vehicles; however, this may not be a widespread phenomenon and depends on individual farm’s willingness to enter into such agreements. With electricity distribution network connection presenting a significant barrier for so many in rural areas, there may be other opportunities to sell energy to a neighbouring site by installing a private wire between two properties. There are regulations which need to be strictly complied with and the viability of this depends upon the individual sites.

    Electricity distribution networks remain a critical component to enable energy ambitions in Scotland to be delivered. This is an issue that is specifically restrictive for farmers, crofters, and landowners in their role in the energy transition[65]. Heat map data published by the Distribution Network Operators on distribution network capacity shows that there are many areas in Scotland which are at or near their capacity limits meaning that new renewable installations looking to export their surplus energy will likely need to wait until network upgrades take place [66]. This can be between £2,000 and £65,000 or more, depending on the number of connections and connection type and energy requirements[67]. This further reduced accessibility to the electricity distribution network and can be a preventative factor for farmers. The Scottish Affairs Committee stated that electricity distribution network connection requires urgent review and investment to ensure net-zero targets can be met through renewable energy generation[68].

    Bioenergy production

    Bioenergy technologies have the potential to supply a low-carbon source of energy to the agriculture sector and more widely. For example, anaerobic digestion (AD) systems which produce biogas could be important to smart sustainable rural energy infrastructure. Farms could provide feedstocks such as crop residues or slurry and local industry could supply food waste. The biogas could be used on farms, to generate electricity or heat, or it could be upgraded to biomethane for use in the gas network or for fuel for farm vehicles or HGVs. In turn, the AD digestate by-product can be used as a fertiliser in crop production, supporting the Scottish Government’s mission to support a circular economy (Blades et al., 2017). Benefits of biogas:

    • Biogas can be used like natural gas to directly heat facilities on site and produce electricity via Combined Heat and Power (CHP). The electricity produced by CHP can be used on site or exported to the electricity distribution network (Auer et al., 2017). Alternatively, biogas can be further purified to biomethane and used to replace natural gas as a fuel for transportation vehicles.
    • Power generation from bioresources is less reliant on climatic conditions than wind turbines and solar PV. Consequently, the export of electricity produced (from biogas CHP) could be of more benefit to the electricity network than other renewable sources of electricity by continuing to generate electricity at times when other renewables are not producing (Sutherland et al., 2015).
    • In addition to harnessing the production of biogas generated from AD plants, or electricity from CHP, there are a stream of potential bioresources produced such as fertiliser, chemicals, gases, and bioplastics which may provide sustainable alternatives to petroleum-based products, both in the agricultural sector and beyond (Reynolds et al., 2022).
    • Food processors, distilleries, and supermarkets can send their waste to AD plants as a feedstock and get recompensed in zero-carbon fuel to run HGVs. During the upgrading process from biogas to biomethane, it is possible to capture CO2 which can lead to the overall technology being deemed as a Negative Emission Technology (NET).
    • Biomethane for AD plants and CHP has lots of potential for specific agriculture sectors, such as dairy farms by using manures, slurries and food wastes or by-products such as whey.

    While there is significant potential, the financial investment and space required mean that AD and biogas production is not usually suitable for small-scale farms, and this is an important limitation to be aware. In addition, injecting biomethane into the gas network is highly regulated by the network operator and requires a legal agreement; specialist equipment as well as a site with a suitable location.

    Conclusions

    The research identifies a wide range of low-carbon technologies available for use on farm. We have identified the strengths and weaknesses of each, and explored their suitability to different situations. Overall, the report identifies the range of technologies available to meet the diversity of on-farm needs for energy use, generation and energy efficiency as a strength for the sector. However, high investment costs coupled with a lack of access to capital are barriers to the uptake of on-site generation using alternative technologies. Poor electricity distribution network access is a barrier to exporting energy generated on site. Regarding costs, the current economic environment is especially challenging for farmers. Many will hesitate to make large investments, whilst dealing with the additional costs to their business caused by the cost of living crisis, and the volatility in both input costs and output values caused by global issues such as the war in Ukraine. In addition to this there is some uncertainty over how future agricultural payments will be structured beyond 2027. The PESTLE table provides more detail of the enabling and preventative factors that can impact uptake of low-carbon technologies on farm.

    The baseline mapping for current energy use on farms and crofts in Scotland from the National Atmospheric Emissions Inventory (NAEI) shows that energy, gas and other fuel use varies greatly across regions in Scotland, depending on the predominant agricultural sector. Livestock sector energy emissions are concentrated to the southwest and north, and arable sector energy emissions are largely from the northeast. Beef is the agricultural sector with the highest overall energy emissions, producing over 100kt CO2e more than the dairy sector (the second largest). Spring barley was the crop with the highest energy emissions in the arable sector, producing more energy related emissions than some livestock sectors.

    The mapping of the baseline emissions indicated that targeting processes that currently rely on other fuels would be the most effective way to reduce agricultural emissions. This may be through identifying opportunities to improve the efficiency of these operations or technologies that enable the electrification of processes that previously relied on fossil fuels. Decarbonisation will be further optimised if the electricity used is generated through renewables.

    Furthermore, it is evident from the data that livestock ‘other energy’ emissions are a substantial contributor to the overall energy use emissions from agriculture in Scotland. Efforts to reduce this through efficiency measures or fuel switching will have a significant impact.

    There were various limitations to the baseline energy emissions mapping, including a lack of data on the predominant fuel type by sector, a lack of publicly available data on current energy consumption, and a lack of detailed data on disaggregated sectors. To overcome these constraints, more detailed and up-to-date data needs to be gathered. This report has not sought to quantify the GHG reduction potential of decarbonising energy use on farm.

    It is evident that farm bioenergy production has the potential to supply Scotland with a low-carbon source of energy for use across the country; however, the land use change required has wider implications on the environment, biodiversity and economics at the farm level and is a topic of debate amongst farmers and the wider public.

    Looking to the future, there is a major opportunity for low-carbon electricity and gas generated on farms to be exported to the grid to support grid decarbonisation. To achieve this, there are significant issues regarding electricity distribution network access which need to be overcome.

    In the correct enabling environment, it is evident that farms can play a significant role in supporting Scotland’s Net Zero targets and just transition and circular economy aims.

    Appendix A: Methodology to task 1

    To establish a baseline of fuel use on Scottish farms and crofts, a literature review was undertaken to provide the typical energy consumed by various agricultural processes. These factors (below) have been applied to the livestock counts and crop areas reported in the agricultural census. This provided an initial indication of fuel use by sector across the agricultural regions.

    The fuel use calculated was not used directly, but rather served as the basis to disaggregate the local authority greenhouse gas statistics[70] (aggregated to agricultural region) into the categories provided in the census (e.g., pigs, potatoes) as this level of detail is not available in the published local authority greenhouse gas data.

    Before the sectoral breakdown could be applied, the GHG statistics were split into urban and rural aspects, with the sectoral split only applied to rural areas. This was necessary as within the NAEI and the LA GHG data, some emissions (including agricultural) are distributed based on employment totals. Full details of how employment statistics are used as to estimate fuel use can be found in DESNZ, 2023[71].

    Using urban boundaries[72], it was possible to calculate the percentage of these emissions which occurred in a rural area and were therefore more likely to be related to actual agricultural practices. This removed the possibility of counting emissions that may be associated with e.g., a farm shop in a city centre.

    Fuel consumption per sector within each agriculture region

    The table below shows the fuel consumption used to disaggregate the local authority greenhouse gas rural energy use emissions.

    List of assumptions setting the scope

    Aspect

    Scope

    Assumption

    Drying of grass for animal feed/silage

    Depends on context

    Out of scope, this would be covered under manufacturing. However, production for on-farm feed and post-harvest storage is in scope.

    Horses/livery

    Out of scope

    Not included in the agricultural inventory, so out of scope.

    Indoor or vertical farming

    Out of scope

    While energy intensive, it is very small scale in market. This will be scoped out. Especially as excluding urban areas for the dataset; some vertical farms will there for be missed. A future study could look at the specifics of decarbonising energy use by vertical farms/hydroponics.

    Manufacturing on site

    Out of scope

    E.g., ice cream or cheese processing on site at a dairy farm; vegetable processing (cut or prepared vegetables); meat processing. This and other similar activities will be covered under the manufacturing inventory. It should be noted that vegetable processing can be complicated to set boundaries with inventories.

    Organic farming

    Included but not separated

    This will be captured with the rest of the data, and it is a small proportion of all sectors. We will not disaggregate it out. A further study could look at the specifics of decarbonising energy use within organic farming.

    On site processing

    In scope

    Packing and processing of fresh vegetables. Some fruit/veg packaged in field during harvest/in packhouses/harvested and stored loose. This is in scope (when on site) as packaging and storing is part of the process.

    Onshore aquaculture/ hatcheries

    Out of scope

    Freshwater fish farms are out of scope as aquaculture does not come under agriculture.

    Transport of animals

    Out of scope (offsite)

    Once offsite, past the farm gate, this is out of scope. A small amount of fuel within the farm gate will cover transport onsite, however, this is generally likely to be low. Most onsite fuel use in mobile machinery comes from farm vehicles used in daily operations for management/herding/transport to wintering housing onsite.

    Urban areas

    Out of scope

    Agricultural practices only occur in rural areas, so data from urban areas are out of scope.

    Energy needs by sector.

    Assumptions of energy requirements for each sector are detailed in the table below.

    Sector

    Energy requirements

    Beef

    Low demands, similar to sheep. Small amount on mobile machinery. Small amount heating for calving and for small amount of warm/hot water for washing

    Cereals

    Drying, necessary requirement in Scotland. Cultivation power, drilling, harvest, transport (to storage on farm)

    Dairy

    Chillers, heating, lighting, small amount of warm/hot water. Some mobile (e.g., spreaders, HGVs needed for on-farm feed production). Some energy needs for robotic milking.

    Fresh peas

    Require chilling. Most peas in Scotland are fresh.

    Potatoes

    Power requirements and storage, chiller, dark house. Depends on variety (seed potatoes). Some mobile machinery.

    Poultry (layers)

    Layers – more steady demands – greater potential savings from improved control and heat recovery in heating, cooling, and ventilation systems. Intensive heat and energy, lighting. Housing.

    Poultry (broilers)

    Broilers – high demand on day 1 – rapidly diminishing heat demand as birds grow. Ventilation demand increases. Intensive heat and energy, lighting. Housing.

    Pig

    Intensive heat and energy, lighting. Housing.

    Sheep

    Small amount on mobile machinery, small amount of electricity or fuel for a generator for sheering machinery. Small amount heating for lambing and small amount of warm/hot water for washing.

    Soft fruit

    Energy intensive for chilling, and for heating of soft fruit growing environment to extend growing season and displace carbon intensive imports. Some mobile machinery, depending on produce

    Appendix B: Methodology to task 2

    • The Rapid Evidence Assessment (REA) methodology used for this project aligns with NERC methodology[73] and comprised of the following steps.
    • Define the search strategy protocol, identify key search words or terms, define inclusion/exclusion criteria. A list of key words, terms and search strings was created and reviewed by the project steering group to direct the REA review to the most relevant sources. This list was supported by Ricardo’s team of renewable energy technical experts and divided into seven relevant categories ‘Mobile demands’; ‘Stationary demands’; ‘Meeting demand’; ‘Generation technology’; ‘Agriculture related modifiers’; ‘Energy related modifiers’ and ‘General modifiers’ to ensure that all appropriate technologies and uses were identified which supported the focus the review. Any literature that is considered out of scope based on our list of assumptions was excluded from the search. We also excluded literature that is older than 10 years, unless it was from a credible source and was the only piece of evidence available (particularly for data).
    • Searching for evidence and recording findings. Literature was searched using Google Scholar and Science Direct, utilising our accounts with Science Direct and Research Gate to access restricted pdfs where required. Grey literature, such as farming press and industry, providing examples of technologies being deployed, was searched using Google. For each individual search a unique search reference was assigned and the date, search string used, total number of results found, and the total number of relevant papers found were recorded. Examples of search strings include:
    • “agriculture” “renewable energy” “Scotland”
    • “agriculture” “renewable energy” “bioenergy”
    • “agriculture” “circular economy” “Scotland”
    • “non-carbon tech” “Scotland” “farming” “land-use”

    All results were recorded in an excel spreadsheet with information extracted on the following:

    • Country
    • Sector
    • Type of technology
    • Benefits and barriers of the technology
    • Cost of technology
    • Opportunity for the technology to support wider decarbonisation of energy production
    • Land use implications (including impact on agricultural production)
    • Opportunity for the agricultural sector to benefit from the second-hand market for renewable/ participate in circular economy.

    A RAG (red, amber, green) rating was assigned to each source, based on the following criteria:

    • Screening. Sources of evidence was then screened initially by title and then accepted papers were then screened again using the summary or abstract. Literature was screened for information on the following inclusion criteria:
    • Non-carbon technology
    • Benefits, enablers and barriers of non-carbon technology
    • Opportunity for technology to support wider decarbonisation of energy production
    • Potential and opportunity for the agricultural sector to benefit from the second-hand market and participate in circular economy
    • Land use implications and the impact on agricultural production
    • Extract and appraise the evidence. The screening provided an organised list of papers which enabled evidence to be extracted directly from the literature into the report. Literature extracted also guided the internal workshop and supported information included in the SWOT and PESTLE tables.

    Appendix D: Extended SWOT tables

    Solar PV

    Strengths

    Weaknesses

    • Low running costs, cost-effective
    • Low maintenance
    • Space optimisation (e.g., when used on rooves, greenhouses (GHs))
    • Protect crops from excessive heat in GHs.
    • More energy efficient (e.g., in grain drying, GHs)
    • Multi-purpose and applicable to a wide range of needs – can be used for drying, heating, water heating, electricity gen, cooling, ventilation – combined with other tech to provide these things.
    • Suitable for off-grid networks
    • Onsite electricity generation reduces costs of activities onsite (e.g., EVs over diesel; heat pumps displacing oil boilers)
    • High compatibility with agricultural activities
    • Reduces emissions compared to FFs.
    • Hybrid wind-solar system – enhanced reliability of energy provision
    • Relatively easy to install – flexibility of the system (scalable)
    • Established solar PV supply chain already.
    • Solar panels in fields can provide shade for small livestock (e.g., sheep & goats), improving animal welfare
    • High initial installation costs
    • Not sufficient energy in rainy seasons
    • Fluctuations in energy generation (can also cause storage problems)
    • Reduced agricultural outputs by taking land out of production or reducing available productive land, for livestock or arable sectors.
    • Training needed to upskill for repairs and maintenance of panels.
    • Solar electric tractor (ET) battery chargers have low efficiency.
    • PVs on farm robots or ETs can overheat.
    • Humidity affects solar ET power output.
    • PVs are only suitable for low-lift small scale irrigation systems.

    Opportunities

    Threats

    • Long term income stream from electricity distribution network exports. Helps to manage costs, reduces imports and reduces risk of fluctuating costs.
    • High potential to power EVs, easily adapted in mechanised farm activities.
    • Agrophotovoltaics (APV) could increase land productivity by about 35-73%
    • APVs are an innovative opportunity to maintain the agricultural function of land while increasing solar generating capacity.
    • Solar PV has high potential in the poultry sector.
    • Diversified farms (e.g., tourism) are more likely to install solar panels onsite.
    • Opportunity for marginal land to be used for solar PV
    • Lack of planning issues for smaller scale solar panels creates enabling environment for potential uptake.
    • Ground under solar panels is left fallow for the duration of the lease agreement; it gives this land the opportunity to rebalance, replenish and recover during periods that may have previously been uneconomical downtime.
    • Opportunity for multiple land uses (e.g., sheep grazing and solar)
    • Integration of PV into a wide range of agricultural components can be a solution to decrease the presence of oil-based fuels on arable lands, avoiding soil contamination.
    • Opportunity for solar to charge batteries for small agricultural applications such as, pumping, electric fencing, lighting, small electronic systems.
    • Potential for recycling solar PV in the supply chain.
    • Many farms have large barns or sheds to mount solar panels.
    • Tenanted farms are less likely to install solar panels.
    • Cloudy weather has a negative impact on solar energy generation storage.
    • Heavy runoff from panels, which can increase soil erosion.
    • Not ideal when solar radiation is low, or it cannot be efficiently used in time when ambient heating is most needed.
    • The production of solar panels has an environmental impact as well from rare metal mining.
    • Electricity distribution network access is an issue for larger commercial projects.
    • Anything over 1kW that is ground mounted needs full planning permission.
    • Social acceptance
    • Change in seasons affecting solar radiation? – Scotland specific

    Onshore wind

    Strengths

    Weaknesses

    • Can be located on agricultural land with low land footprint.
    • Modern wind turbines have low noise pollution.
    • Hybrid wind-solar system – enhanced reliability of energy provision
    • Reliable in windy areas (such as Scotland)
    • Requires little maintenance over a long period of time. Maintenance conducted by external contractors so not taking up time of staff on site to maintain.
    • Long-term investment (long lifespan, around 20-25 years)
    • Established supply chain (skilled people available for installation)
    • Cheap renewable energy technology that is price competitive with new clean coal power stations
    • Flexible and scalable – ranging from one small turbine to several large units.
    • Access tracks and paths needed to install and reach wind turbines can also provide access for local communities and off grid farms
    • High initial investment despite falling costs in recent years.
    • Long payback time, depending on the size of the turbine and energy generation and usage.
    • Noise pollution is worse in larger turbines.
    • Threat to wildlife, especially birds and bats
    • Highly visible
    • Can degrade high carbon soils when poorly located.
    • Depending on the unit size there are differences in suitability for location.

    Opportunities

    Threats

    • Livestock can graze the base of the wind turbine, so productive area is minimally impacted.
    • Ideal for remote locations in Scotland
    • Long term income stream from electricity distribution network exports. Helps to manage costs, reduces imports and reduces risk of fluctuating costs.
    • Existing second-hand market for wind turbine parts in Scotland provides room for low-cost uptake.
    • Wind farms on Scottish cropland are found to generate more energy and have higher carbon opportunity costs than other land use types.
    • Wind turbines are more likely to be situated in areas with high wind speed, high latitude and altitude, and in holdings with large sheep flocks, making it ideal for Scotland.
    • The UK (and Scotland) has some of the best wind resources in Europe.
    • Opportunity for wind to charge batteries for small agricultural applications such as water heating, pumping, electric fencing, lighting, small electronic systems.
    • Potential for knowledge sharing and adapting successful wind projects to local purposes provides a resource with significant potential.
    • There is an opportunity for large wind turbines to power big electricity generators and support an uptake of electric vehicles (EVs). The significant wind capacity in Scotland combined with other technologies can overcome constraints associated with EVs, especially in remote areas.
    • Wind has the potential to play a part in just transition, with a focus on uptake in rural areas or areas with poor energy access or network connection
    • Limited existing electricity distribution network access
    • Scotland has many zones of natural heritage and designated sites, such as AONBs, RAMSAR sites, national parks, and others. These can affect planning permission acceptance, especially for larger wind developments.
    • The opportunity cost of wind farms do not provide the monetary support in agriculture that can economically compete with the financial benefit generated by wind energy.
    • Farms that engage in tourism are less likely to have wind turbines on the property. As farms seek diversification this can present a threat to uptake.
    • Social acceptance: negative public opinion of wind turbines due to visibility
    • Government policy and support is inconsistent, which makes investment a risk.
    • Wind farms situated in upland peatland areas damage peat during construction, and tracks over moorland damage flora.
    • Trees have been known to be removed during access to construct turbines.
    • Wind farms on undegraded peats are likely to further increase carbon emissions.
    • Compliance with crofting legislation – projects on croft land or common grazing require further action and planning considerations.
    • It is difficult to find someone to maintain second hand market parts and insurance is not always available for second hand wind turbines

    Hydrogen

    Strengths

    Weaknesses

    • Hydrogen is a non-toxic fuel and disperses quickly when released.
    • Does not produce carbon emissions at the point of combustion and only produces water if electrochemically combined with oxygen.
    • Hydrogen powered vehicles when compared to EVs, avoiding the need for charging tools. However, significant infrastructure is required for hydrogen use.
    • The capital cost of a hydrogen internal combustion engine will not be much more expensive than diesel versions equivalent by 2030.
    • Extensive trials on hydrogen retrofitting fuel cells on tractors have shown lots of benefits, e.g., fuel savings that have ranged from 11% to 29% and a reduction in emissions of up to 80%.
    • Green hydrogen can be produced during off-peak periods or times when there is excess renewable electricity, instead of curtailing the excess energy.
    • Hydrogen can store energy for a long duration. E.g., renewable energy system can generate hydrogen which can then be stored for long periods.
    • Hydrogen vehicles can store more energy and therefore have a higher working range than EVs.
    • Hydrogen vehicles are lighter than EVs so they can navigate difficult terrain more easily
    • There are few pilot projects demonstrating hydrogen in the agriculture sector.
    • The high energy requirement of hydrogen production – 1kg hydrogen requires approximately 400kWh of electricity – means a lot of power is required and therefore on-site production is most suited to farmers that already have renewable energy generation on site or have ample space to install more.
    • As hydrogen is a gas, challenges arise in trying to store and contain it. This causes a logistical problem as specialist infrastructure is required through the supply chain to compress, contain, transport, store and refuel.
    • High capital cost/initial investment in on-site storage and refuelling infrastructure. Much higher cost if on-site production is planned.
    • Green hydrogen is currently both hard to come by and expensive, with costs that will unfortunately be passed to the farmer.
    • Highly-combustible, prone to leakage – can be dangerous when storing on site, and there are requirements for storage and use under UK-wide Health and Safety Executive guidelines. UK has a strong track record in using hydrogen safely.
    • Low volumetric energy density.

    Opportunities

    Threats

    • An alternative hydrogen-production process could be achieved in which agricultural wastes and various other biomasses can be recycled to produce it. Farmers can be given the tools to generate their own green fuel, eliminating the need for costly, imported fossil fuels. The by-product carbon dioxide can be carbon negative if sequestered, earning extra revenue.
    • Can be used in farm machinery to cut emissions, without the complications that come with heavy EV batteries.
    • Landowners have space to develop on-site renewable power generation for localised hydrogen production.
    • As a growing proportion of Scotland’s energy production comes from renewable sources located in rural areas, there is the potential for hydrogen production from electricity distribution network connection.
    • Hydrogen and renewable power systems on-site have the potential to create local renewable energy communities in remote areas, providing energy to surrounding farms and businesses.
    • There are already UK-wide capital and revenue incentives for hydrogen, such as the Net Zero Hydrogen Fund[75] and the Hydrogen Business Model
    • The Scottish Government has a Hydrogen Action Plan and Route Map to 2030 and 2045, supporting investment in hydrogen[76]
    • The major problem in utilization of hydrogen gas as a fuel is its unavailability in nature and the need for expensive investment in supply chains.
    • Public refuelling infrastructure in the UK is still lacking.
    • An adequate electricity distribution network connection for on-site production can be expensive and take a long time to be implemented, particularly in rural environments.
    • There is little policy consideration for hydrogen in rural context.
    • Current market players are focussed on contracting with larger scale customers.
    • Margins are fine in the agricultural sector and red diesel (untaxed) is cheaper than hydrogen.
    • NOx emissions are still present from combustion but can be managed to low levels via lean combustion or flue gas recycling.
    • The hydrogen sector is relying on technological improvements and at-scale manufacturing to reach long-term cost competitiveness.
    • Hydrogen in a rural context is a nascent area and new developments and innovations are expected, but currently the evidence base for applications of hydrogen are limited to pilot projects which could scale, such as HydroGlen at Glensaugh Farm, which is run by the James Hutton Institute and received Scottish Government funding[77].

    Bioenergy

    Strengths

    Weaknesses

    Various types of bioenergy can be used to replace fossil fuels.

    Solid Biomass

    • Well-developed technology
    • Woody Biomass contributes to GHG emissions mitigation in the energy sector since it displaces fossil fuels with high carbon content.
    • Woody biomass (e.g. Short Rotation Coppice) contributes greater soil carbon sequestration during growth in comparison to cultivated crops in the same area.
    • Benefits of SRC, miscanthus & forestry – reduced erosion and improved flood reduction
    • Marginal land can be used for SRC.

    AD/Biogas/Biomethane

    • Makes use of raw materials and by-products straight from the farm/onsite, manages waste from livestock farming, helping reduce the need for storage, maintain environmental safety, reduces GHG emissions and stimulating the development of local economies.
    • Waste to biogas using AD is considered most environmentally friendly due to minimum carbon leakage and positive waste resource recycling impact.
    • Safe treatment and disposal of agricultural waste
    • By-product from AD is digestate which can be re-applied to soils as an organic fertiliser.
    • Use of slurry for AD reduces methane emissions that would arrive from slurry storage.

    Liquid biofuels e.g., biodiesel and bioethanol

    • Ethanol has a competitive price in the market.
    • Non-toxic, biodegradable, free of sulphur
    • Works in any diesel engine with few or no modifications
    • Biodiesel provides mobile machinery users with an alternative fuel that will allow ‘business as usual’ operation. Each engine model will have stipulations for the maximum percentage of liquid biofuels that can used without modification to the engine. Some engines can operate on 100% liquid biofuels by volume.

    Solid Biomass

    • High cost for maintenance of biomass boilers, especially in comparison to other options and boilers. Issue with unreliability and need for overhaul (high CAPEX)
    • High competition in the wood fuel market
    • Forestry biomass can be of unreliable quality and supply is not always guaranteed.
    • Air quality can be a concern for farms nearby urban areas.

    AD/Biogas/Biomethane

    • Gate fees remain a significant deterrent for farmers (who can simply land spread their untreated livestock waste for free)
    • Significant investment required.
    • AD plants require large footprint.
    • Upgrading of biogas (50–65% CH4) to biomethane (>90% CH4) is costly and energy demanding.
    • AD will often not be suitable for small-scale farms.
    • Lignocellulosic rich waste streams require pre-treatment before AD to improve methane yield.

    Liquid biofuels e.g., biodiesel and bioethanol

    • Dedicated land for growing crops for biofuels would be in competition with human/animal feed production.
    • FAME’s (Fatty Acid Methyl Ester) is often associated with more maintenance issues than fossil fuels.
    • Current production of perennial energy crops in Scotland is very low.
    • Some suboptimal use – use for financial incentive but not always the best tech for specific uses. Previous incentive schemes encourage uptake.
    • Producing biofuels is not energy-efficient (Biofuel)
    • GHG reduction is modest compared to other measures (Biofuel)
    • High costs and complexity of the logistics and supply chain management
    • Developments in biomethane infrastructure are needed for natural gas transport fuels to be feasible (N Ireland)
    • Storing and transporting biodiesel and pure plant oil
    • Securing feedstock can be challenging (AD)
    • AD recovery yield can vary widely depending on feedstock and operational conditions applied.
    • Suitability of technologies to some buildings (e.g., Biomass boiler)
    • Range of biomethane tractors may not be sufficient for a full day’s work.
    • (Case study) Cost of putting the kit in to clean up the biogas to make biomethane, and then to compress it into a tank to fuel a tractor, was not competitive with red diesel.
    • Biodiesel is water intolerant and thickens at temperatures below 0 degrees Celsius, therefore, shelf life is limited and is more complex to store than fossil diesel.
    • Technology take off for pure plant oil due to technical limitations.
    • wood pellets and contracted energy crop come at a large financial cost.
    • transport of manure (CAD)
    • Few commercially available biomass CHP systems available on the market other than those based on anaerobic digestion (biomass CHP)
    • Current high costs of HVO (Hydrotreated Vegetable Oil) (biodiesel)

    Opportunities

    Threats

    If combined with carbon capture and storage, bioenergy can be deemed as carbon negative.

    Solid Biomass

    • The use of forest and agricultural residues does not compete with crop production.
    • Pyrolysis and gasification of solid biomass produces a by-product known as biochar which can be used as a soil improver, animal feed supplement and for water treatment.
    • Ash from combustion can be used as a fertiliser.

    AD/Biogas/Biomethane

    • Biogas can be used like natural gas to directly heat facilities on site and produce electricity via Combined Heat and Power (CHP)
    • Biogas can be upgraded to bio-hydrogen via steam reforming.
    • Cellulosic feedstocks grow well on marginal lands (cellulosic biomass crop) (biofuel)
    • biogas and electricity production in terms of techno economic evaluation is feasible in all types of dairy farms, which allows the self-sufficiency of energy based on organic waste (Biogas)
    • Price support in the past has led to exponential increases in uptake; future price support schemes could do the same (Biogas)
    • An AD plant can provide a constant base load of energy to help fill the gaps created with other intermittent energy supplies (case study)
    • There are opportunities for local AD plants and agricultural waste biomass plants on islands in Scotland, reducing the communities’ carbon footprint due to removing the need to ship waste to the Shetland Island for disposal (case study)
    • Wider point on value derived from resources that are not fully used to their full potential – circular economy.
    • Supply of bioresources is often not sustainable – stringent sustainability criterion needs to be imposed.
    • Uncertain farm-scale profitability of biogas
    • Taking fields out of food production (biogas, biofuel, and biomass) (STFA said this will take 10,117ha of Scotland’s best arable land out of production for the agricultural industry, threatening supplies of straw (AD)). However, the RTFO[78] has a ‘crop-cap’ to mediate this.
    • Cultural and declining significance of Scottish crofting by land use changes related to the uptake of bioenergy crops (Land use)
    • global demand for food production could lead to an increase in arable farming (land use)
    • There are barriers to developing biomass energy production technology.
    • Changing energy policy complicates the financial appraisal of AD projects.
    • Agricultural reuse of anaerobic digestate as potential renewable fertiliser can pose some hygienic and environmental hazards as well as storage issues (due to the limitation of land disposal imposed by the Nitrates Council Directive)
    • AD plants which use distillery co-products, such as draff, pot ale and dark drains, as a feedstock have constrained supply and increased their prices. This had had a knock-on effect for farmers who purchase these products as animal feed.
    • If there were to be widespread adoption of biomethane as an alternative fuel for agricultural mobile machinery in Scotland, there would likely be large pressures on biomethane production and availability.
    • concerns with the effects of potential ‘methane slips’ in biomethane machinery

    Hydropower

    Strengths

    Weaknesses

    • Low maintenance costs of hydro-powered water pumps due to their simple construction features, which leads to a maximum equipment lifetime, and are thus more efficient.
    • Reliable and suitable for agricultural uses
    • Micro-hydro schemes tend to give a more constant generation compared to wind or solar PV.
    • Micro-hydro systems also have low maintenance and a life expectance of 25 years or more.
    • Once installed, hydro schemes are relatively unobtrusive and very quiet.
    • Most systems should last 30-50 years
    • In terms of agriculture, uptake will still be limited by site suitability, high capital cost, the need to obtain an abstraction licence.
    • Hydropower water pumps are not popular due to a limited number of locations, site-specific environmental problems, lack of suitable water flows, and negative ecological effects.
    • Seasonal variation in streamflow causes variation and disturbance in energy supply.
    • Hydroelectric generation is currently the highest volumetric use of water in Scotland. The development of large-scale hydroelectric schemes has had an extensive impact on the water bodies of the Highlands.
    • Reserving large volumes of water in reservoirs for generation purposes is technically a form of water use, and the sheer volume of flows involved can impose environmental costs and (economic) opportunity costs.

    Opportunities

    Threats

    • There is considerable scope in Scotland for the development of further small-to-medium sized installations, particularly for run of the river (RoR) type.
    • RoR types have potential to make contribution to Scotland’s renewable energy targets, especially as hydropower technology is mature and the resource is generally considered to be less variable than alternatives such as wind.
    • Small scale hydropower development may help to meet renewable energy and carbon emissions targets while also offering opportunities for diversification and employment in rural communities.
    • Planning permission often smoother than for other renewable projects
    • This is a potential renewable energy source for agriculture that could offer controllable electricity production. small dams with turbines were one of the first options for mechanical force generation (e.g., mills) and electricity production in the agricultural sector.
    • If the electricity distribution network is to be significantly extended in the future, for example when building connections for other renewable technologies such as wind, it is possible that more hydropower would also become economically feasible.
    • Need for planning permission.
    • High cost of making efficient connections to the existing electricity distribution network.
    • During dry summers an increased demand for irrigation water in agricultural areas may lead to further reductions in energy generation capacity.
    • ambitious targets for afforestation set out in the Scottish Land Use Strategy[79] have the potential to change evapotranspiration rates and thereby alter runoff characteristics in some regions.
    • Licensing can be challenging.
    • Electricity distribution network connection and land ownership can be two of the biggest limiting factors.
    • Where a watercourse forms the boundary between two farms, formal permission from the neighbour will be needed.
    • Flooding is a potential risk, so sites should be designed to ensure generators and electrical equipment are above the flood level and bypass channels may be needed to divert flood water

    Heat pumps

    Strengths

    Weaknesses

    • Multi-use – can be used to provide simultaneous heating and cooling – according to season (heat in winter and cooling in summer) and/or function (e.g., cold store and greenhouse).
    • More financially viable when there is a heating and cooling demand (e.g., grain drying plus potato cold store) – offers savings that are not possible using other technologies.
    • High energy efficiency – produce 3-5 units of heat for each unit of consumed electricity.
    • GSHP (ground source heat pumps) with underfloor heating and fan coil units provide even distribution of heat throughout poultry sheds.
    • Passive cooling removes excess heat from the sheds. Circulation pumps then return it to the ground where it is stored for future heat cycles. Farms can therefore switch from heating to free cooling without affecting response times.
    • GSHP suitable technology for crop and grain drying floors.
    • Despite the initial disturbance to land, excavations only need to go down to 1.2m – once the plant is installed, pastureland recovers quickly.
    • Less fire risk for drying systems operating on heat pumps than diesel generators which dry products using combustion gases.
    • Installation costs can be high but with both heating and cooling demands heat pumps can become more financially attractive.
    • Need certain amount of space for ground collectors.
    • The supply chain for installation and maintenance of heat pumps is still developing.
    • Depending on the relative price of gas and electricity, sites may have increased running costs when switching to a heat pump from fossil fuel heating plant.
    • Ground-source heat pumps require ground disruption – impact on drains and under below ground services need to be managed carefully.
    • Sites with on high electricity tariffs may have increased running costs when switching to a heat pump from fossil fuel heating plant.
    • Sites may require an electricity distribution network capacity upgrade.
    • In the context of agriculture, heat pump systems will be larger and more specific than domestic settings, therefore maintenance costs can be high.

    Opportunities

    Threats

    • For sites with renewable power generation, heat pumps can utilise this to reduce operating costs and carbon footprint.
    • Heat energy is the second largest energy use in the agricultural sector, as much of this heat is relatively low temperatures it is ideal for heat pump applications.
    • Opportunity for use in dairy farming – chilled water from heat pump can be used to chill milk from 18°C to 3.5°C using a one pass plate heat exchanger.
    • Heat pumps can recover waste heat and upgrade it to desired temperatures.
    • High Temperature Heat Pumps (HTHPs) are beginning to become available
    • Payback period depends on relative gas and electricity prices.
    • Most heat pumps provide temperatures of up to 50-60°C therefore for space heating application, user needs well insulated property or must increase radiator area. However, high temperature heat pumps (HTHPs) are becoming available.
    • For sites with high heat pump utilisation, risk that ground loop reduces soil temperatures thereby potentially impacting arable land

    Electric vehicles (EV) and Electrification

    Strengths

    Weaknesses

    • Lower operating/fuel costs, improved accuracy.
    • Low wear and maintenance costs.
    • Are noise and pollution free at point of use.
    • Electric motors are up to three times as efficient (compared to traditional combustion engines) when using a battery as the energy source and a fully electric drive train.
    • If the electricity is produced from renewable sources, the CO2 reduction potential is near 100%.
    • Electrification enables the use of renewable energy produced on farm, using wind, photovoltaic solar or bio-digestion.
    • Farmers can charge their machines at their own farm (provided they have the infrastructure) – meaning they are not reliant on public/nationwide charging infrastructure rollout.
    • Robots can repeat almost all activities with greater accuracy, which supports precision and energy efficiency
    • The main limitation of battery electric vehicle (BEV) technology is the inability to currently support all necessary farming activities at its current state of maturity.
    • Due to lithium-ion battery technology’s low energy density, to reach the same levels of power in a BEV alternative would require an unfeasibly heavy and large battery to be used (resulting in issues such as soil compaction).
    • Charging infrastructure barriers and considerations that currently affect use include:
    • Power of charging – needs to be powerful enough to charge machinery to the required amount – tend to be heavy duty vehicles.
    • Speed of charging – Sufficient time to charge is required, to enable a full charge to maximise use before charging is required again.
    • Charging infrastructure with inadequate power/speed may also lead to trade-offs including longer working days for farmers, reduced total field time, or having to recharge multiple times a day. Potentially reduced operation time (depending on power/speed of charging – see above).
    • High purchase/production costs associated with batteries, their replacement, and price of agricultural electricity can significantly affect life cycle costs, affecting viability for farmers.
    • There are environmental concerns relating to battery production, including procurement of rare minerals/material required and associated GHG emissions of these activities.
    • Robotics – Initial capital investment costs are likely to be prohibitive to small farms.

    Opportunities

    Threats

    • Significant opportunities for emission reduction potential in the future as electrification matures (including reduction in costs over time).
    • Current BEV alternatives have the potential to replace diesel mobile machinery in small scale horticulture, indoor fruit growing and grounds maintenance activities.
    • There are more opportunities for heavy use farms to replace with EVs due to higher/faster vehicle stock replacement cycles.
    • Vehicle-to-grid (V2G) technology can result in EVs being used as decentralised electric storage resources, leading to the creation of a new income stream.
    • More potential economic benefits of using BEVs for agriculture – low operating costs and opportunities for better exploitation of in-site renewable energy sources.
    • Advances in the technology will enable UK vehicle manufacturers to develop new products that span the transition from the current diesel-powered farm vehicles to the robotic farming systems – the UK is well placed to implement these changes due to its strong automotive sector in industrial and agricultural vehicles, with extensive infrastructure already in place.
    • Possibility/allowance to do operations close to the farm for charging or indoor applications.
    • Electrical power offers greater controllability and opportunities for implement automation e.g., precision seeding.
    • Robotics – CEMA (European Agricultural Machinery) suggest precision farming and smart machine technology rank among the most cost effective GHG reduction measures for agriculture in the years to come.
    • Systems are in use and under development for autonomously monitoring livestock and collecting field data, all commercially useful for efficient and productive livestock farming.
    • Small robotic platforms with low to medium power ratings will be suitable for selective harvesting, weeding, logistics support, or crop care
    • Biodiesel, biomethane, and hydrogen are currently considered to be more suitable for arable applications, largely due to charging requirements. However, the availability of each of these fuels, alongside the cost of the technology and its associated infrastructure is a significant barrier (so also a potential opportunity).
    • Terrain of rural roads and seasonal changes can negatively impact upon predicted range and user experience.
    • Varying agriculture vehicle stock replacement rate/ lifecycle – large diesel vehicles are likely to remain in practical use for many years to come, and when they are replaced, are often used in the second-hand market Low use / smaller farms/holdings are also likely to have longer replacement cycles or be more cautious about moving to alternatively fuelled vehicles.
    • Robotics – the UK RAS (robotic and autonomous systems) community has no specific training paths or Centres for Doctoral Training to provide trained human resource capacity for RAS within Agri-Food.
    • There is a concern that RAS for Agri-Food projects being commissioned currently are too few and too small-scale

    Appendix E: Extended PESTLE table

     

    Enabling factors

    Preventative factors

    Political

    • Government policy such as the renewable obligation certificates that incentivise renewable energy uptake in Scotland can bring down costs and increase uptake on large farms.
    • The Scottish Government’s Community and Renewable Energy Scheme (CARES) programme supports communities to engage with and benefit from the energy transition to net zero emissions. Local communities can access funding to install renewable technologies.
    • Feed in Tariff (FiT) support schemes provides investment in small-scale renewable projects up to 5MW capacity.
    • Political will for decarbonisation (e.g., 2045 net zero targets for Scottish Agriculture)
    • The profitability of the farms producing renewable energy is now vulnerable to the institutional arrangements of the energy regime and its sectoral policies.
    • Government policy is inconsistent, which makes investment in renewable energy a risk.
    • Conflicting policies and targets can impact uptake (e.g., afforestation targets can indirectly divert water away from hydropower installations)
    • Lack of regulation over nascent technologies (e.g., hydrogen, robotics)

    Economic

    • Capital grants or support schemes can help farmers shoulder on-farm costs and encourage uptake.
    • Larger scale installations can offer opportunities for diversification and employment in rural communities.
    • There is a general desire to diversify farm income.
    • Energy price rises driving change.
    • Supermarket requirements driving change down the value chain.
    • Integrated business strategies focusing on just transition and diversification (e.g., making the most of your site
    • Agricultural sector is a large part of Scottish rural areas and islands, meaning there are many areas in scope of potential uptake of renewable energy on farms.
    • Purchase of equipment for collective use within communities
    • High initial capital expenditure requirements for most renewable technology installations
    • Lack of access to capital and grants and uncertainty in available capital to invest.
    • Economic viability of farmers: future uncertainty heightened by agricultural transition and changes in support payments since Brexit.
    • Increase in prices of rural land due to bioenergy crops and corporate and private interest in land for carbon and nature-related offsetting.
    • There is a conflict between agriculture and tourism businesses in islands and other rural areas, which can lower availability of specific renewable elements (e.g., biomass)

    Social

    • Rural and local energy communities can work together to support and create micro-grids and install renewable technologies through community action and crowdfunding, enabling access to renewable energy in remote locations.
    • Peer-to-peer learning and community support for education
    • Legacy on farm – longer term view to support future generations with more renewable energy generation (even in some tenancies)
    • The energy and agricultural regimes compete for use of agricultural land, both functionally (food vs. fuel) and in terms of control (farmer vs. corporations)
    • Negative public opinion of large-scale renewable technology installations
    • Issues around access to equity, especially for farmers in lower socio-economic bands
    • Potential at govt level to say that things are coming rather than farms fighting the battle – collective top-down support.
    • Contract/short term tenant farms less likely to be able to implement renewable technologies due to contract and communication difficulty with landlords.
    • Land ownership – corporations/wealthy people buying up land for carbon sequestration and ‘CSR’ purposes.
    • Competing land pressures in central Scotland – e.g., housing; other pressures
    • Changing uses of land not always in favour of tenant farmers

    Technical

    • Many renewable energy technologies are already widely used across Scotland
    • Poor current electricity distribution network access, especially in rural and remote areas.
    • Electricity network constraints – there is a limit to scalability.
    • New or rapidly evolving technology (hydrogen, robotics) create an investment risk, due to deployment issues or a risk of obsolescence.
    • People are cautious based on experiences of ‘cowboy builders’

    Legal

    • Small scale installations and microgrids can benefit from permitted development rights where planning permission can be granted without the need for local planning authority applications.
    • Environmental permitting – driving change for reduction of emissions on site.
    • While important for other reasons, planning requirements or restrictions in certain areas (e.g., designated sites, AONBs) can hamper the uptake of renewable technologies (especially wind turbines and solar panels).
    • Licenses for water abstraction (e.g., for hydropower) can hamper uptake.
    • Land ownership and tenancies can cause disputes over implementing renewable technology, leading to slow uptake.
    • Land ownership issue – wider engagement needed to implement tech if tenanted (expand) – access etc.
    • General binding rules – restrictions on water use (e.g., AD)
    • Cleaner air for Scotland strategy – combustion technology (e.g., bioenergy) barrier
    • Inheritance tax considerations for changes in agricultural land use for some renewable energy production types.

    Environmental

    • Changing climatic and environmental conditions due to climate change can positively affect the capacity renewable energy techs (e.g., increased sun exposure from hotter and drier summers)
    • Many farms have the resources (e.g., agricultural residue) or space (e.g., marginal land) available to support biomass energy production and the installation of other technologies.
    • Positive environmental and biodiversity benefits from bioenergy crops in comparison to managed grasslands or arable crops (relative to the ecosystem)
    • There are competing land pressures in central Scotland (e.g., housing/ afforestation). Additionally, renewable energy projects normally require large amounts of space to capture the energy in wind, water, or solar radiation in sufficient quantity to be commercially viable.
    • Changing climatic and environmental conditions due to climate change can negatively affect the capacity renewable energy techs by increasing uncertainty in weather conditions.
    • Need to identify the negative environmental impacts on installing (e.g., installing wind turbines on peat land)
    • Intensification of land for biomass production previously not used for cropping (e.g., land use change from grasslands to bioenergy crops)
    • Negative environmental and biodiversity implications from the growth of bioenergy crops (relative to the ecosystem)

    Greenhouse gas emissions across the agricultural supply chain need to reduce in order to meet the targets in Scotland’s Climate Change Plan update. As the majority of emissions in the agricultural supply chain are generated at farm level, farmers face pressure to take mitigating action. At the same time, commercial operators are expecting an increased demand for low-carbon goods from consumers, including food. Detailed evidence on the extent and nature of private sector drivers of on-farm climate action is lacking.

    This research provides an overview of the evidence for private sector drivers for climate change action in Scottish agriculture. The researchers undertook a rapid evidence review of the available literature in combination with stakeholder interviews.

    Summary of findings

    The main driver placed on Scottish agricultural producers from the private sector is to complete baseline carbon audits of their current operations. Although this is as yet not widespread, it is common in some sub-sectors and is anticipated to rapidly spread across the whole industry.

    • There is little evidence to suggest that the process of carbon audits and action plan creation has led to significant emissions reduction in Scottish agriculture at the producer level.
    • The evidence strongly suggests that farmers respond primarily to policy and market signals, although the balance between these varies across sectors.
    • Consumer preferences shape the food products that retailers, wholesalers and processors market and sell. Consumer demand for low carbon goods is set to increase, and so decarbonising value chains will be part of staying in business in a competitive market.
    • The UK retail industry is largely consolidated into a handful of large organisations, which possesses significant leverage over producers. Industry expectations suggest that mitigation demands placed on upstream suppliers will increase rapidly.

    Further details on the findings can be found in the report attached.

    The Scottish Government is committed to support the transition to net zero, whilst restoring and regenerating biodiversity. Organic farming practices have the potential to deliver to both agendas.

    This rapid evidence assessment and stakeholder engagement assesses the evidence for organic farming practices that contribute to the Biodiversity Strategy targets, a reduction in greenhouse gas emissions and making Scottish agricultural systems more resilient to the projected climatic conditions of 2045.

    The review assessed greenhouse gas emissions in terms of both a reduction in emissions and an increase in soil carbon.

    Key findings

    The stakeholders emphasised that organic farming is a holistic approach to farming the land, and benefits arise from the combination of management practices adopted. The literature review supported the holistic nature of organic farming.

    The research found that:

    • Organic farming practices offer benefits to biodiversity, greenhouse gas emissions, soil carbon, and how organic farming practices might help farmers adapt to a changing climate in Scotland over the next two decades to 2045.
    • The inclusion of specific measures such as leys and cover crops, organic bulky materials and crop residue management in organic systems tends to increase the soil carbon.
    • Organic systems are typically more diverse than conventional systems.

    Conclusions

    The wider adoption of organic farming practices will benefit the environment. This would require support for the industry to transition and maintain the system. Advice and training would be required.

    Agriculture accounts for around 24% of Scotland’s greenhouse gas emissions, of which methane accounts for around 44%. A significant proportion results from generation of manure and slurries in livestock production.

    Anaerobic digestion is a biological process that generates a methane-rich biogas from resources such as manure and food waste. When carried out under controlled conditions, the biogas can be captured and converted to energy for heat and electricity.

    The Scottish Government has recognised the potential for farmyard slurry to contribute to renewable and bioenergy ambitions. The 2021 Bioenergy Update recognised a need to examine the potential for a Scottish market for digestate – the nutrient-rich material produced by anaerobic digestion, which can be a good fertiliser. Having a market for digestate would remove constraints on greater production of biomethane.

    This report examines the potential to reduce emissions by processing agricultural wastes through anaerobic digestion plants. The focus is on agricultural wastes that consist mainly of animal manures and slurries, which are highly underutilised resources.

    Conclusions

    • Anaerobic digestion is an important tool in the fight against climate change. However, manures and slurries do not yield high volumes of biogas and the latter typically has a low dry matter content. This means it is uneconomical to transport it to the large-scale AD plants that currently exist.
    • On-farm plants are particularly suitable for farms generating liquid slurries throughout the year, such as dairy farms. Such plants can therefore operate all year round to produce biogas and/or electricity consistently.
    • Manure and slurry-only farm-scale solutions are available, but there has been little uptake in recent years as policies have driven economies of scale. Although solutions exist, there is low visibility of farms running, in a profitable way, easy-to-operate micro-scale solutions that would be appropriate for individual farms.
