Prof. Dr. Klement Tockner

Director General of  Senckenberg Society for Nature Research

Freshwaters host a remarkable biodiversity, including one-third of all vertebrate species. In addition, freshwaters provide a wide range of ecosystem services that are fundamental for human well-being, including clean water, recreation value, and food. However, freshwaters are under immense and increasing human pressure due to overexploitation, habitat degradation, invasion, climate change, dam construction, as well as emerging stressors such as light, noise, and synthetic chemicals. Hence, we need to carefully, and fundamentally, rethink future management strategies and support coordinated actions to reverse the decline of biodiversity. We need to advocate for hybrid approaches that manage freshwater as a crucial resource for human life support as well as highly valuable and diverse ecosystems. Most urgent, however, is the preservation of the remaining free-flowing rivers, intact wetlands, and unspoiled lakes—for the benefit of humans and nature alike. Otherwise we threaten the viability of our next generations. It is not yet too late to reverse irresponsible trends in climate change and biodiversity loss.
