Research of the working group focuses on methods for an environmental economic valuation of ecosystem services. The concept of ecosystem services is the fundamental link between the natural sphere of ecosystems and the human sphere. Ecosystem services comprise all the benefits that humans obtain from nature. Generally, these are classified into provisioning services (food, natural resources etc.), regulating services (water purification, climate regulation, pollination etc.), habitat/supporting services (habitat for organisms, reservoir of genetic diversity) and cultural services (recreation, spirituality etc.). Since often ecosystem services are public or common pool goods, their value cannot easily be inferred by market prices. Therefore, if policy makers are interested in how much people value, i.e. like or benefit from, these services, special techniques for the valuation of non-market goods must be employed.

In this context, the Environmental Economics group employs and analyzes so-called Stated Preference methods like the Contingent Valuation Method (CVM) or Choice Experiments (CE). We are particularly interested in the question to what extent these methods can unveil and validly measure the different types of ecosystem services so that they can be used for practical policy making.

The working group has experience with CVM analyses in Germany as well as in various countries of SO-Asia (China, Philippines, Thailand, Vietnam). Please see the projects listed below for detailed information.

Apart from research on the valuation of ecosystem services, the working group is actively engaged in the fields of environmental management, sustainability management and reporting, sustainability benchmarking and economic analyses regarding renewable energies.
