Prevent before repair: What a new hydrology-based index reveals about river ecological status

When I first began analysing agricultural pressures in German river networks, I expected the familiar story of nutrient loads, pesticide traces and differences between landscapes. What I did not expect was how narrow the ecological safe operating space has become for many rivers. Even small increases in agricultural pressure, especially from pesticides, reduced the likelihood of achieving good eco ...[Read More]

When we think of hydropower, its environmental impacts usually comes to mind: the dams that disrupt ecosystems, the water bodies that shift, the surface evaporation that increases, and the greenhouse gases that escape from reservoirs1. Hydropower, for all its clean energy potential, is not without its environmental baggage, whether on local water resources or the global surface water storage. But ...[Read More]
