| In the context of climate change and a steadily rising demand for energy the concept of a bioeconomy stands for a shift from fossil fuels to bio-based energy sources. In Germany the National Strategy on Bioeconomy promotes biomass as an energy carrier to meet the federal government’s ambitious targets for bioenergy generation. Inevitably this requires an expansion of energy crop cultivation which increases pressures on soil resources by reducing soil resistance to erosive forces. Policies need to ensure that an intensification of energy crop cultivation is not increasing soil degradation as soil is not only crucial for the bioeconomy but also contributes to the provision of several ecosystem services. As soil erosion by water is the most severe threat to European soil the focus was on regulations for erosion control. The policy analysis of relevant legislation at EU national and regional level and the GIS-analysis of regional implementation practices revealed several shortcomings: Only few policy instruments set binding standards for erosion control. Furthermore local authorities can undermine the risk assessment process and the resulting soil management restrictions. The GIS-analysis revealed an underestimation of erosion risk of approx. 24 % regarding the total area of Saxony which was chosen as an example. This could be linked to a low quality of data within the assessment process. Local authorities balancing farmer’s interests and soil conservation were identified as another risk which has the potential to significantly decrease the effectiveness of the current legislation. In cases of noncompliance with compulsory requirements subsidies can be reduced. However due to limited resources on-the-spot-checks are rare and penalties not necessarily transparent. |
