Summary
This modelling study applied process-based simulation to predict how climate change may alter nitrous oxide emissions from grassland soils in south-west England. Using field observations and climate projections, the authors quantified the sensitivity of N2O release to temperature and water availability changes, providing regional-scale estimates relevant to UK grassland management and greenhouse gas accounting. The work contributes to understanding of how shifting climatic conditions may affect non-CO₂ emissions from pastoral systems.
UK applicability
The study is directly applicable to UK grassland management and policy, providing regionally-specific estimates for south-west England that inform national greenhouse gas inventories and climate mitigation strategies for pastoral agriculture. The findings are relevant to informing management practices to reduce N2O emissions under projected climate scenarios affecting British grasslands.
Key measures
Nitrous oxide (N2O) emissions from grassland soils; temperature and precipitation sensitivity; regional emission projections under climate scenarios
Outcomes reported
The study used process-based modelling to predict how projected changes in temperature and water availability under climate change scenarios would alter N2O emissions from grassland soils in south-west England. Regional-scale estimates of N2O flux sensitivity to climatic drivers were quantified using field data and climate projections.
