Dr R.C.H. Aben (Ralf)
Employee - Aquatic Ecology and Environmental Biology
Ralf Aben has a broad interest in the biogeochemistry of ecosystems on land and in water. His focus is on greenhouse gas emissions from freshwater ecosystems and drained peatlands. What are the major sources of GHG emissions in these systems and what influences them?
Ralf is currently working as a postdoc researcher within the Dutch National Research Programme on Greenhouse Gases in Peatlands (NOBV), a program that was started as a result of the National Climate Agreement of the Dutch government. The aim is to study the effectiveness of various measures to reduce peat oxidation and GHG emissions, and to improve our ability to predict GHG emissions from peat soils under different conditions and mitigation strategies. Climate mitigation measures include passive subsoil irrigation, active (pressurized) subsoil irrigation and paludiculture.
The NOBV research program is carried out by a consortium of 8 parties (Deltares, Radboud University, VU University Amsterdam, Wageningen Environmental Research, Wageningen University, B-ware Research Centre, Kytalyk Geoscience and TU Delft) and is funded by the Dutch government, several provinces and water boards.

- 2019 - For peat meadows, a reduction of the annual emission of 1.0 Mton in 2030 has been laid down in the Climate Agreement. What are the effects of various measures against subsidence on greenhouse gas emissions? How do the measures that have been developed, or are still being developed, to limit emissions work? And what role do soil life and water quality play in peat degradation, for example? In order to answer these questions, the National Research Program Greenhouse Gases in Veenweiden (NOBV) has been conducting research since 2019 at various locations, where various measures and situations are measured. Greenhouse gas fluxes (CO2, nitrous oxide and methane) are measured at all locations. The soil chemical and soil physical properties are also investigated and soil subsidence is measured. The research is being carried out by a consortium of various universities and knowledge centres, with a subsidy from the Ministry of Agriculture, Nature and Food Quality under the direction of STOWA.
