Science that matters

The diversity of whitefish species in Swiss lakes is unique and plays a central role in lake ecosystems. A comprehensive Eawag report now summarises the results of 150 years of research on these fish. They make it clear that the mechanisms and environmental conditions that have contributed to their development must be taken into account in order to preserve this species diversity. Last but not least, protecting whitefish diversity helps to preserve the natural yield potential of lakes as a source of food for humans.

Professor Urs von Gunten is one of the world's best-known scientists when it comes to the treatment of drinking water, in particular oxidation and disinfection processes. He has been conducting research at Eawag since 1989, with interruptions; from 2006 he was a titular professor at ETHZ, and from 2011 a full professor at EPFL. Now he is retiring. He retains a consultancy mandate... and the freedom to critically scrutinise the narrative of Switzerland's leading role in research.

To enhance biodiversity in water and on land, we need high-quality, interconnected natural areas. Here the cooperation of different stakeholders is essential.

To contain the spread of the invasive quagga mussel, Eawag researchers recommend swift action based on comprehensive prevention, early detection and containment.
