How much water is left for nature? The search for the appropriate environmental flow

In many rivers, only a small amount of streamflow remains for nature after water is diverted for hydropower production. In light of climate change and biodiversity loss, this is having increasingly serious consequences. Researchers from WSL, UZH and Eawag have compiled an interdisciplinary overview and highlighted areas where knowledge gaps exist.
