October 4, 2023In just 16,000 years, more than 500 cichlid species, distributed throughout the entire food web, have evolved in Lake Victoria. This explosion of biodiversity was made possible by repeated cycles of fusion and diversification in evolutionary lineages, as researchers from Eawag and the University of Bern have described in the “Science” and “Nature” journals. The results underscore that it is not just species that need protection, but entire “species swarms”.

September 28, 2023There are many challenges that face cities in the era of climate change and rising population density, including heatwaves, floods, water shortages, loss of biodiversity and increasing demand for energy. Eawag is researching how these problems could be mitigated using blue-green infrastructure.

September 21, 2023The ETH Board announces the appointment of Sara Marks as a new member of the Eawag Directorate. On 1 November, Sara Marks will replace Tove Larsen, who will retire at the end of October 2023.

September 19, 2023During prolonged droughts, the drinking water supply for the affected population is critical. Water filters are of enormous importance in such emergencies to prevent diseases. However, often it is not the distribution of filters that is lacking, but the fact that they are not used consistently in everyday life. Researchers at the Aquatic Research Institute Eawag have analysed the reasons for this in Northern Kenya.

September 14, 2023At today's Eawag Info Day, the Aquatic Research Institute outlined the steps that need to be taken to achieve the Sustainable Development Goals (SDGs).

September 7, 2023Timely analyses of the bacterial community in wastewater treatment plants enables changes to be detected and remedied before cleaning performance suffers.

September 4, 2023The 4 research institutes of the ETH Domain strengthen cooperation and build bridges between research and innovative solutions for today's challenges.

August 24, 2023This can indirectly affect the survival of fish populations and may be one of the reasons for the fish decline we are currently observing in Switzerland.

August 22, 2023Green spaces or trees can mitigate urban heat, but it takes time for the cooling effects to develop. Modelling using satellite data can show how much time is needed.

August 17, 2023The combined sewer system is a great achievement. But the discharge of diluted wastewater into central sewage treatment plants is approaching its limits.
