Ecosystem services and energy crops – spatial differentiation of risks

The increased cultivation of energy crops has a variety of economic, social and environmental effects, which can be assessed using the concept of ecosystem services (ES). Among the various instruments for regulating energy crop cultivation, reducing the impacts on ecosystems and landscapes, and moving sustainable land management forward, the ES concept is a useful tool since it includes economic, ecological and social aspects. The methodological approach is exemplified by a case study in the district of Gorlitz, Germany. It started with an indicator-based analysis of the present state of landscape functions or services, focusing on the “supply” part of ES assessments. The results were interpreted in light of an ecological risk assessment concerning intensified agriculture in general and the increased cultivation of energy crops in particular: on the one hand for the present situation, and on the other, for three different future scenarios. It was possible to project the results onto reference units (biophysical units), and to reveal spatial differences in carrying capacity or sensibility as a result of increased energy crop cultivation. The demand side of ESs was assessed on the basis of semi-structured interviews and standardized questionnaires.
