EU-peatlands: Hotspots for GHG-emission? Drösler & Veenendaal Out of 43 European countries the ten biggest peatland emitters are contributing 46300 Gg CO2-C equivalents or 90% of total European GHG emissions from peatlands. Less than half these emissions are from EU-25.
EU-peatlands: Hotspots for GHG-emission? Drösler & Veenendaal Significance For EU-25 the significance of peatland GHG emissions is about 2-3% of anthropogenic emissions. For Germany peatland emissions represent 2.3-4.5 % of the anthropogenic emissions and are a major source in the land sector. So even in a highly industrialized country like Germany peatland emissions are a hotspot.

EU-peatlands: Hotspots for GHG-emission? Drösler & Veenendaal Conclusions • Spatial variability matters: • water table • vegetation type • management • peat characteristics • ….. • Peatland-Landscape composed by a small scale mosaic of parameter combinations => specific requirements for site selection, measurement techniques and upscaling approaches • Temporal variability matters: • interannual variability • time since restoration • Multiyear measurement programmes and/or revisiting of sites required

EU-peatlands: Hotspots for GHG-emission? Drösler & Veenendaal further needs • Only few year round GHG budgets based on continuous measurements for peatlands. • Representation of different climate zones up to now only limited. • Peat depths and bulk density profiles are not well-known in much of Europe, and are a key item in calculating current carbon stocks and long term accumulation rates. • There is particular need for more data about GHG budgets of peatlands under particular land uses: a) bog: grassland, cropland, land abandoned after peat cut, restoration, forest chronosequences, N2O fluxes in general. b) fen: abandoned after harvest, restoration, CO2 fluxes in general. General: differentiation of intensity. • There are insufficient data to characterize greenhouse gas flux sensitivity from peatlands to the full potential of weather variability and climate change. • The assessment of restoration effects on GHG-fluxes needs more measurement programs and process studies, to cover variability in time and space.
