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.
