Policies for ecosystem services enhancement
Ecosystem services have increasingly been highlighted as central to human wellbeing1,2,3. Ecosystem services refer to the various benefits that humans gain from nature and functioning ecosystems. Four groups of ecosystem services are commonly recognized: provisioning (e.g. food, drinking water, fibre), regulating (e.g. climate, disease control, flood prevention, waste-water self-cleaning), supporting (e.g. nutrient cycling, crop pollination, maintenance of genetic diversity), and cultural (e.g. recreation, spiritual)4 services.
