Reducing Ghg Emissions By Abandoning Agricultural Land Use On Organic Soils
6.5% of the German UAA is located on organic soils (fens and bogs). Nevertheless, the drainage of these areas in order to allow their agricultural utilization causes roughly a third of the greenhouse gas emissions (GHG) of the German agricultural sector, being equivalent to 4% of the total German GHG emissions. Obviously, German policies trying to reduce the GHG emissions successfully must tackle this issue. The abandonment of the cultivation of organic soils would be an effective policy to reduce the GHG emissions however the question remains whether it is an efficient measure compared with the other options? In the paper we compare the land use on mineral and organic soils using the data of the farm structure survey. We assess the mitigation costs on the basis of the standard gross margin of the agriculturally used peatlands and with the sector model RAUMIS. Without engineering and transaction costs the mitigation costs are in the magnitude of 10 to 45 € per to of CO2eq.. This makes rewetting of peatlands at least in the medium and long run a fairly efficient options for reducing GHG emissions, especially as the implications on the sector are fairly small due to reallocation affects.
