Climate Change: Peat Bogs

Answer

Peat bogs are a significant store of carbon which needs to be protected. We are looking at rehabilitating peat bogs as one possible way of protecting existing carbon stores and biodiversity. However, this is technically challenging due to the presence of naturally occurring underground water channels which develop in response to artificial drainage. These would continue to have a drying effect, even if surface drains were blocked to rehabilitate bogs. In terms of offsetting carbon emissions through increasing this store, the potential is somewhat limited due to the slow accumulation rates of active bogs. In addition, some healthy peat bogs can be a significant source of methane. It is important to see the potential contribution of peat bog restoration in proportion to many other ways we are seeking to reduce greenhouse gas emissions. We are now developing a programme of work to co-ordinate peat protection activities across government. We are also undertaking research to improve our understanding of the main mechanisms by which carbon is lost from peats; the impacts of land use and land management; and to develop practical methods for mitigating losses. This will form a key part of the forthcoming soil strategy for England. In addition, the current review of environmental stewardship will examine how the scheme can further help to address climate change, including halting the decline of upland carbon stores.
