Prof. Chris Evans

Terrestrial and aquatic ecosystem biogeochemistry, with a focus on semi-natural and managed uplands and peatlands. Interests include:

• Trends and drivers of change in dissolved organic carbon (DOC) export from terrestrial to aquatic ecosystems.
• Field-scale measurement of fluxes and controls on the carbon and greenhouse gas (GHG) balance of natural, managed and restored peatlands in temperate and tropical regions, and the potential role of restoration and mitigation measures in reducing GHG emissions.
• Sources, processing and fate of terrestrially-derived organic matter in aquatic ecosystems, from headwater streams and lakes to estuaries and coastal waters, and the contribution of this flux to anthropogenic GHG emissions
• Controls on the cycling of atmospheric nitrogen and sulphur in terrestrial ecosystems, including controls on leaching to surface waters, ecosystem nitrogen saturation, recovery from acidification, the role modifying land-use factors such as forestry, grazing and burning, and links on the carbon cycle.
• Impacts of climatic fluctuations and extreme events on hydrological and biogeochemical processes, particularly in relation to water quality extremes and their ecological impacts.
• Ecosystem-scale biogeochemical modelling of the impacts of atmospheric N and S deposition, ozone (O₃), climate change and land-use on terrestrial productivity, C balance, soil and water chemistry and plant species diversity.
• Synthesis of scientific understanding to take account of multiple anthropogenic drivers and ecosystem functions in support of policy, particularly in relation to land-management. 

Research experience

• 20 years of research experience in upland and peatland biogeochemistry, including carbon and nitrogen cycling, greenhouse gases and water quality, process modelling, long-term and large-scale data analysis. Interests include the effects of changing atmospheric deposition on freshwater acidity, nitrogen and dissolved organic carbon (DOC) loss; land-use and deposition impacts on peatland greenhouse gas emissions; long-term environmental change impacts on terrestrial and biogeochemistry and biodiversity; and the translation of scientific process understanding into policymaking and ecosystem service valuation.
• Principal investigator on projects for NERC, Defra, DECC, Welsh Government, conservation agencies and the Forestry Commission with a total value exceeding £3.5m.
