Water regulation is considered as one of the main regulating ecosystem services by SEEA-EEA. It includes water retention, storm and high water protection (including flood control) and it is also closely related to erosion and sedimentation control as well as water purification. An important characteristic is that all of them can be regarded as both...

Ecosystem services (ES) are the contributions of ecosystem structure and function (in combination with other inputs) to human well-being. This implies that mankind is strongly dependent on well-functioning ecosystems and natural capital that are the basis for a constant flow of ES from nature to society. Therefore, ES have the potential to become a...
