As part of the opening event of the BMBF joint project REKLINEU – "Regional Pathways to Climate Neutral Universities" – the public evening lecture by Prof. Dr. Matthias Drösler from Weihenstephan-Triesdorf University of Applied Sciences will take place on December 14, 2022, 6:15 pm. The topic of the lecture is climate protection through peatland conservation. The basic characteristic of peatlands is the storage of carbon through the build-up of organic matter as a result of incomplete decomposition under naturally water-saturated conditions. This process has been ongoing in Europe since the last ice age and has resulted in peatlands being the largest terrestrial carbon stores per unit area. For the climate relevance of peatlands, however, it is not primarily the C-pool but the balance of the exchange of climate-relevant trace gases that is decisive. In a near-natural state, peatlands are +/- climate neutral, since the uptake of CO2 and the release of CH4 compensate each other with respect to the global warming potential. However, only about 5% of the peatlands in Bavaria are still in near-natural condition. Most of them are drained and used for agriculture or forestry. As a result, the moor soil is aerated, aerobic degradation begins and the moors develop into hotspots of climate pollution.
The lecture will explain the basics of the climate relevance of peatlands, present the current balances for Bavaria and outline the options for action to achieve climate protection goals: The challenge of using peatlands as CO2 sinks will be considered on a technical organizational and strategic/legal level.
