Decision-making: Empirical analysis of actors supplying and demanding ecosystem services  Hide

Decision-makers from regional to global scales do shape the supply and the demand for ecosystem services. With this research we want to investigate how the decision-making is influenced by perceptions of ecosystem services as well as by climate change, markets and policies. In this context we analyse how ecosystem services are considered in German environmental law.

Regional human-environment systems: Mapping and modelling of land use, biodiversity and ecosystem servicesHide

To map the physical quantities and the socio-economic value of ecosystem services is an important input into landscape planning on regional to national scales. In this research we explore the use of ecohydrological models and remote sensing in order to investigate the delivery of services. This is linked to the spatial distribution of the demand for ecosystem services to assess their socio-economic value. Based on this our goal is to develop spatially explicit models based on agent based models and to apply them in case studies in Germany and South Korea.

Interregional flows of ES: Assessing virtual land/water and ecosystem impactsHide

The global trade of commodities enables countries to expand their land area virtually and at the same time to export the impacts on ecosystem services worldwide. With our research we want to quantify the flows of virtual land and water embedded in commodity trade (e.g., of the EU) and quantify its impacts on ecosystem services on a global scale. Beyond that other interregional flows of ecosystem services are investigated.

Tools: Integrating land-use, biodiversity and ecosystem services into Life Cycle Assessment (LCA)Hide

Life Cycle Assessment is a tool increasingly used by decision-makers in industries and governments for the analysis of products with respect to environmental impacts. The goal of our research is to integrate the assessment of land use impacts on biodiversity and ecosystem services into this method. This improvement should allow to assess e.g., biofuel production more realistically.
