Global change scenarios predict an increased risk for declining amounts of soil organic matter (SOM) for Cen-tral Germany. Within this region the production of bioenergy is one important strategy to counteract the rising anthropogenic CO2-emissions. Both issues have a close connection: SOM is an important basis for soil produc-tivity and requires a steady reproduction flux (Crep). Bioenergy production requires productive soils and partly consumes plant biomass carbon. Therefore, the available amount for SOM reproduction is reduced. This study provides a methodology for the large-scale identification of areas with possible conflicts between bioenergy production and SOM reproduction based on i) the prediction of climate change impact on SOM reproduction and ii) an analysis of the regional distribution of biogas plants. The study has been published in Franko et al. (2015).
