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.

A conflict is developing in Africa’s Lake Victoria between fish farming in cages and the “normal” fishing industry. Added to that are other factors such as invasive species, wastewater pollution, pesticides and dam construction are putting the unique ecosystem under increasing pressure.  Read more

Although chemical micropollutants are known to affect the ecology of natural waters, it has remained unclear how they do so. An Eawag study has now shown that increasing concentrations of pharmaceuticals and personal care products reduce the diversity of algae in a lake, giving rise to more homogeneous communities with a reduced capacity to adapt to fluctuations in environmental conditions.
