A major challenge for agriculture is the need to manage soils to reduce greenhouse gas (GHG) emissions to contribute to climate mitigation targets. Most research in this area is focused on lowland farming, but this challenge is also of high relevance to the uplands, which cover a third of the UK and act a major soil carbon (C) store. Grazing is the main form of upland land management, and it has been proposed that facilitating soil C storage through improved grazing management could offset GHG emissions to mitigate climate change. Working with partners Natural England and The National Trust we are studying how grazing influences soil C storage and GHG emissions in upland grassland. Our ultimate goal is to provide mechanistic understanding of the effects of grazing that can be used to formulate land management strategies for climate mitigation in the uplands. This project is funded by BBSRC with field studies being performed at Ingleborough National Nature Research and Malham Tarn, in the Yorkshire Dales.
