How can the decisions taken across agriculture, forestry, water management, biodiversity and planning all support each other to benefit the natural environment, support sustainable local businesses and create healthy rural and urban communities?
The Land Use Strategy for Scotland is the first of its kind in the world, taking a holistic approach to land use management, and recognising that different sectors are inextricably linked. It places climate change at the centre of the principles to guide actions.
Agriculture and associated land use is the second largest source of greenhouse gas emissions in Scotland, behind the transport sector. (Source: Scottish greenhouse Gas Emissions 2016)
The Committee on Climate Change has warned the Scottish Government that the lack of emission reductions in sectors like agriculture puts the Scottish climate change targets at risk.
Forests are important carbon sinks, and the Scottish Government is committed to increasing forest cover. This also has benefits for biodiversity and resilient silvi-culture. But a warmer wetter climate can also pose significant risks to tree health through extreme weather events or increased spread of pest and diseases.

A quarter of Scotland is covered by peat – an important carbon sink which also prevents flooding, filters water and provides important habitats.
The condition of peatlands is important for how well it captures and stores carbon. Peatlands that dry out will release carbon and contribute to climate change. Some peatland management practices have contributed to this through drainage, heavy grazing or inappropriate burning. The Scottish Government has targets for on-going restoration of degraded peatlands.
Soils are a critical resource not only for food production and biodiversity but also for managing water and storing carbon.
Climate change will impact soil wetness, soil temperature and soil degradation, including loss of organic matter, erosion and compaction as a potential result of changing rainfall patterns. This all impacts on how well the soil performs:

All land use decisions play a role in how well we can manage increased rainfall and changes in rainfall patterns and extreme weather events. Hard flood defences can disrupt natural processes and increase flooding in other parts of a catchment.
Scottish Government policy favours Natural Flood Management, which includes restoring and enhancing natural features and characteristics to slow and contain flood water.
A key research need across land use is to analyse the early impacts of climate change, and assess how different measures can contribute to reducing emissions and managing the impacts.
To achieve this we promote cross-sectoral dialogue and research that can directly inform land use policy options. We also provide systematic evidence reviews to understand the state of confident knowledge across traditional disciplinary boundaries.
Our work is helping to tease out where tangible change might be achieved in modern farm business practice.
Our projects explore new farming techniques and their practical application, models to track emissions intensity and life cycle analysis. There is a particular interest in the potential for improvements in the livestock production sector and our research contribution is collected here.
We are involved in testing and demonstrating sustainable forestry practises.
We provide applied research on how forest expansion and restocking can support outcomes including carbon sequestration potential, biodiversity, shelter for animals, timber production and increased resilience to extreme weather events.
Soil is a fundamental resource for Scotland, underpinning our society, economy and environment, and it is important to understand the factors essential to its sustainable management.
Research in this area looks at how soil protection and management is a feature of a range of policy areas and how they can work together.
Peatlands play an important role in the carbon cycle and are increasingly becoming a focus point for policymakers and researchers. They also deliver a wide range of other benefits including to water, agriculture and biodiversity, which impact on both public and private interests. if damaged they become a source of greenhouse gas emissions, but when restored have potential to store significant amounts of carbon. Examples of early work are captured here.
Our projects examine a wide breadth of interests, from the potential abatement from peatland restoration, exploring issues with restoration methods and understanding the extent of peatland that has been drained in Scotland, to analysing the practical implications of a revision to the International Inventory for Wetlands under the IPCC.
Our study on the current state of science on the impact of burning on peat and peat soils was a timely contribution to the review of the Muirburn Code in Scotland.
Our suite of indicators of climate change risks, impacts and actions gives a detailed picture of the health of the natural environment as the climate changes.
We derive a wide range of benefits from how we use the land; it underpins our economic prosperity, supports the provision of essential supplies of food and clean water. Its sustainable management is essential to how we reduce our greenhouse gas emissions, and adapt to a changing climate. CXC projects explore the way land is managed and the options that might support more integrated approaches in the longer term.
