Applicants are invited for a PhD fellowship/scholarship at Graduate School of Technical Sciences, Aarhus University, Denmark, within the Ecoscience programme. The position is available from 01 November 2023 or later. Title: Recovering peatlands for global change mitigation
Research area and project description: Rewetting of low-lying drained organic soils is proposed as an efficient nature-based solution to reduce greenhouse gas emissions and nutrient export from agriculture. However, we lack knowledge of the efficacy of rewetting for these ecosystem services, as different strategies have not been tested in field studies.
In a multidisciplinary field experiment linking soil microbes, geochemistry, greenhouse gas emissions and hydrology, ReverCit will test a novel restoration strategy called topsoil-removal by measuring greenhouse gas and nutrient fluxes coupled to soil microbiology. Topsoil removal is expected to enhance the reduction potential, compared to increasing groundwater levels only, because the most reactive peat substrate is removed.
The major outcome of ReverCit is to quantify the underlying hydrological and biological processes in rewetted soils with and without topsoil removal that will highlight benefits and limitations of this potentially more sustainable rewetting strategy. The research in ReverCit will be conducted at a Danish “living wetland lab” in Vejrumbro, which was fully instrumented for monitoring hydrology, CO2 and CH4 fluxes and nutrients in 2022 as part of the national research infrastructure project ReWet.
Senior researcher Dominik H. Zak (ECOS, AU), will be the principal investigator (PI) of the project. His core expertise is on biogeochemical processes in soils concerning phosphorus, nitrogen, carbon, and iron cycles.
The project team consists further of associate professor Jesper R. Christiansen (IGN, KU), specialised in linking soil hydrology, field studies of GHG measurements and microbial communities and Professor Susanne Liebner (HC, GFZ), specialised in the microbial C cycle and microbial communities and microbiomes in peatlands.
