PhD defence: Rewetting of peatlands – a tool to mitigate climate change

Rewetting of peatlands to mitigate climate change has been a hot topic in recent years. However, detailed knowledge on climate effects following rewetting including ‘paludiculture’, the productive land use of rewetted peatlands for biomass production, was lacking.

During her PhD studies, Claudia Kalla Nielsen studied how soil-specific biogeochemical drivers affect greenhouse gas emissions for different peatlands before and after rewetting, as also under different paludiculture management options. Further, Claudia studied how paludiculture grass biomass can be used for the production of green protein in biorefineries.

The new research findings contribute to the understanding of peat soil biogeochemistry and the effects on sustainable peatland management practices on greenhouse gas exchange. These answers are vital to enhance the efficiency of rewetting as a nature-based solution to climate change mitigation, while offering sustainable land use options.

The PhD study was completed at Department of Agroecology, Faculty of Technical Sciences, Aarhus University.
