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.

Species-rich ecosystems are more resistant to disturbances such as droughts, heatwaves or pesticide inputs – that, at least, is the view widely held by scientists and non-scientists alike. In fact, the situation is more complex, as ecologists from Eawag and Zurich University have now discovered. Under certain environmental conditions, increased species diversity can also lead to an ecosystem becoming more unstable. Read more

Mountain rivers swollen by heavy rainfall deposit large amounts of sediment in reservoirs. To prevent the loss of storage capacity, some reservoirs are equipped with bypass tunnels which convey sediment-laden waters to downstream reaches. The fact that such tunnels offer ecological benefits as well as economic advantages was shown, for example, by a study carried out on the Solis reservoir in Graubünden. Read more
