Ecosystems provide many different services to mankind. Services provided depend on how the land is used – land use decisions lead to trade-offs that with respect to the ecosystem service provided by ecosystems and landscapes. This trade-offs vary in many situations in space and time. Therefore, it is essential to quantify and map service provisioning [...]
