Water scarcity exacerbates the effects of multiple stressors, and thus results in decreased water quality. It impacts river ecosystems, threatens the services they provide, and it will force managers and policy-makers to change their current practices.

River ecosystems are subject to multiple stressors that threaten their ecological status and the ecosystem services they provide.
River ecosystems are subject to multiple stressors that threaten their ecological status and the ecosystem services they provide. This book updates the reader’s knowledge on the response and management of river ecosystems to multi-stress situations occurring under global change.
Managing and restoring aquatic ecosystems affected by multiple stressors is a key contemporary challenge for environmental scientists, managers and policy makers. As we’ve documented on this blog over the last few years, many european water bodies are subject to multiple human pressures such as pollution, climate change, hydrological and morphological alterations.
