Lowland agricultural peat: water for peat pilots
Published 31 January 2024
Why peat matters
Peatlands contain over half of England’s terrestrial carbon stores. In their natural state, peatlands play a vital role in trapping carbon and also provide a wealth of wider benefits such as improved ecosystems and biodiversity, better water quality and natural flood management.
Since the 1600s, our lowland peatlands have been drained of water to create drier soils suitable for conventional agricultural use and food production. In England, only 13% of our peatlands remain in a near-natural state and, in low-lying peatlands (the lowlands), this figure drops to less than 1%. When peatlands degrade in this way, soil is lost, the land subsides, and the carbon once stored in the soil is lost to the atmosphere, primarily as carbon dioxide.
Lowland peat soils provide some of our most productive farmland. Without a change to how these peatlands are managed, we will continue to lose valuable agricultural soils, leading to loss of agricultural land and greater challenges to food security. In parts of the lowlands, the Climate Change Committee estimate that there is only enough peat soil left to continue farming as we do now for another 20 to 50 years.
What the government is doing
The government is committed to building on the recommendations of the Lowland Agricultural Peat Task Force Report. The report highlighted the importance of transforming water level management and water infrastructure in lowland peat landscapes.
Our best option to return peat to health condition is through rewetting - safely and sustainably raising and managing water levels within the peat soil. However, we need more information on how to best to go about rewetting, and in which areas of lowland peat it is possible and appropriate.
Defra’s lowland agricultural peat policy team, in collaboration with partners, have several ongoing projects exploring paludiculture, socioeconomics and wider research and development. This work, combined with the water for peat pilots, will inform the design of future lowland peat policy.
This will in turn enable farmers to continue to produce food on lowland peatlands and will deliver benefits for drought- and flood-resilience, improvements in water quality and biodiversity and significant reductions in greenhouse gas emissions, helping us on our way to achieving our net zero commitments.
