It confirms that climate change is already affecting land productivity, food security, and ecosystem services globally. Rising temperatures, changing rainfall patterns, and increased frequency of extreme events like droughts and floods are impacting agricultural yields and degrading natural ecosystems. The report also highlights that land-based climate mitigation options, such as reducing emissions from agriculture and forestry, and increasing carbon sequestration through ecosystem restoration, are essential but have limits and potential trade-offs.

Furthermore, the SRCCL emphasizes that sustainable land management practices can significantly contribute to climate change adaptation and mitigation. This includes adopting climate-smart agriculture, sustainable forest management, and ecosystem restoration. The report also stresses the importance of addressing socioeconomic factors, land tenure, and governance issues that influence land use decisions and sustainable practices. For England, these findings point towards the need for robust policies that support sustainable agriculture, enhance biodiversity, and promote carbon sequestration in soils and forests.

Link Between Land Use and Greenhouse Gas Emissions

The report unequivocally links human land use activities to significant greenhouse gas (GHG) emissions. Agriculture, forestry, and other land use (AFOLU) activities are responsible for a substantial portion of global GHG emissions, including carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O). Deforestation, land degradation, livestock farming, and the use of synthetic fertilizers are major contributors. Deforestation alone accounts for a significant share of global CO2 emissions, releasing stored carbon into the atmosphere.

Conversely, land also offers substantial potential for mitigating climate change by sequestering carbon from the atmosphere. Soils, forests, and other ecosystems act as natural carbon sinks. Sustainable land management practices, such as afforestation, reforestation, improved soil management, and wetland restoration, can enhance this carbon sequestration capacity. The report stresses that balancing the need for land resources—for food, fiber, and bioenergy—with the necessity of maintaining and enhancing land’s role as a carbon sink is a critical challenge for climate mitigation efforts worldwide, including in England.

Impacts on Food Security and Water Resources

Climate change, mediated through land systems, poses significant threats to global food security and water resources. The SRCCL details how rising temperatures, altered precipitation, and extreme weather events impact crop yields, livestock productivity, and fisheries. Land degradation further exacerbates these issues by reducing arable land and water availability. In many regions, including parts of England susceptible to drought or flooding, these impacts can lead to reduced food availability, price volatility, and increased food insecurity.

Water resources are also critically affected. Changes in precipitation patterns, increased evaporation rates due to higher temperatures, and melting glaciers (less relevant for England, but globally significant) impact water availability for agriculture, ecosystems, and human consumption. Sustainable land management practices are crucial for conserving water resources, improving water use efficiency in agriculture, and managing watersheds effectively. Addressing these interconnected challenges is vital for ensuring resilient food systems and secure water supplies for populations worldwide, including England’s.
