In England, lowland peat occupies around 960 km2 and stores large amounts of carbon. Nearly all lowland fen peatland has been drained to provide some of the most fertile agricultural soils in the UK. However, drainage has resulted in loss of peat (with rates of ~1 cm/yr under intensive agriculture) and associated high CO2 emissions. Until recently, there had been limited scientific focus on the greenhouse gas (GHG) fluxes from lowland peatlands, but recent studies involving several of the supervisors have highlighted their scale, with intensively farmed lowland peatlands now known to be the largest land-based source of GHG emissions in the UK (Figure 1). To date, almost no research has been undertaken on agricultural management options to reduce C loss and GHG emissions whilst also improving soil health. This project provides a unique opportunity to study the effects of implementing more sustainable farming management practices on soil and climate security. An improved understanding of the strategies available for fenland farmers will provide important insights as to whether alternative agricultural management strategies on peat soils can provide emissions mitigation and other co-benefits, in comparison to conventional land management. This will provide data which will help inform landscape-scale feasibility planning for reduced GHG emissions, improved biodiversity, natural reserves, and ecosystem CO2 uptake by the CASE partner, Cambridgeshire County Council who are a major agricultural land-owner in the Fens.

在英格兰，低地泥炭占地约960 km2，并存储了大量碳。几乎所有低地的泥炭地都被排干，以提供英国一些最肥沃的农业土壤。但是，排水导致泥炭损失（在密集农业下的速度约为1 cm/yr）和相关的高二氧化碳排放。直到最近，低地泥炭地的温室气体（GHG）通量的科学重点有限，但是最近涉及几位主管的研究强调了它们的规模，其规模很高，目前众所周知，该植物是英国最大的陆地泥炭地，现在是英国最大的陆地基础。迄今为止，几乎没有对农业管理方案进行的研究，以减少C损失和温室气体排放，同时也改善了土壤健康。该项目提供了一个独特的机会，可以研究实施更可持续的农业管理实践对土壤和气候安全的影响。对芬兰农民可用的策略的深入了解将为与传统土地管理相比，在泥炭土壤上的替代农业管理策略是否可以提供减轻排放和其他共同利益的重要见解。这将提供数据，以帮助景观规模的可行性计划，以减少温室气体排放，改善生物多样性，自然储备和生态系统二氧化碳的摄入案件，案例伙伴剑桥郡县议会是费斯的主要农业土地所有者。
