Biodiversity

Preserve biodiversity

Concerns about the preservation of biodiversity often end up on the losing side when it comes to weighing conflicting interests in the balance, and its loss is usually only quantified in financial terms when it is already too late. Eawag is researching what biodiversity really means, what benefits it brings, and what measures can be employed to preserve it.

May 13, 2022As of 1 May 2022, Andrin Krähenbühl will head the FIBER fisheries advisory service at the Swiss Federal Institute of Aquatic Science and Technology (Eawag) in Kastanienbaum. The biologist and angler brings with him experience from research and association work. And he is convinced that it serves everyone if the institutions work well together: fisheries, research and biodiversity.
