The Schwarzer Schöps case study is located in the Eastern Germany close to the border with Poland. The catchment area is about 136 km², of which most is used as cropland (54%) and grassland (20%). The area is facing an increase of severe floods, soil erosion, and droughts, with negative implications for crop yield stability. In addition, the downstream reservoir Quitzdorf suffers increasingly from low water tables and high phosphorus pollution. This causes increasing blue-green algae blooms which impair the reservoirs´ multiple services, in particular its important role for nature protection, recreation, and maintaining downstream environmental flows.
