The ecosystem study aimed at creating hypothetical scenarios for alternative future developments of selected dams of the lower Lahn and at exploring their potential positive and negative impacts on ecosystem services delivery. The study intended to quantify the respec-tive impacts on ecosystem services, and to complement this information with monetary valua-tions as far as possible. The study considered both conventional biotic ecosystem services such as water retention, recreation and habitats, and abiotic services , primarily the use for navigation and hydropower.
This manuscript presents key results from the technical report in German and consists of a translated synthesis of two paper manuscripts based on the technical report (Mehl et al. 2022 a and b, also in German).
