Simulation of Future Climate Change Scenarios on Experimental Wetlands within Climate Control Chambers
The research project focuses on wetland ecosystems; both natural (peatland) and constructed wetlands as well as lakes receiving the corresponding outflows of both systems. Wetlands are one of the most productive ecosystems in the world. They may provide numerous ecosystem services such as flood control, water purification as well as climate change mitigation and adaptation if properly managed. Wetlands are vulnerable to climate change, alterations in hydrological regimes and temperature, which all might affect these ecosystems strongly and subsequently, change their role in the landscape. To have a sustainable wetland, which can respond well to climate change, stress factors should be prevented or at least reduced by a sustainable management approach. In this project, we have conducted mesocosm experiments within four climate chambers to simulate the impacts of current (2016-2018) and future climate scenarios (RCP 2.6, RCP 4.5, RCP 8.5) on peatlands and constructed wetland as well as their lake recipients. We aim to assess climate change adaptation strategies for wetlands receiving stormwater run-off to improve water quality and prevent greenhouse gas emissions. This aim is supported by these objectives: (a) to assess different climate scenarios on system performances; (b) to evaluate degradation processes during periods of low and high water levels; (c) to interpret biogeochemical processes such as brownification due to peatland degradation, stormwater treatment by wetlands and lake eutrophication; (d) to investigate carbon emissions from the peatlands; and (e) to optimize the water level management within wetlands to increase their efficiency.
