July 23, 2025Surprisingly little is known about the climate history of the greater Tibet-Himalaya region. However, this information is urgently needed to predict how climate change will alter the water cycle there. Information stored in the sediments of Tibet's Nam Co Lake should now allow new conclusions to be drawn. A video presents the project.

July 15, 2025By the end of the century, water temperatures in Swiss rivers will rise by up to 3.5 degrees if no action to protect the climate is taken. The rivers in the Alps are particularly affected. This is the conclusion reached by researchers from Eawag and the University of Basel in a research project funded by the FOEN.

July 3, 2025Two workshops on urban development and biodiversity with participants from research and politics show how cities can be designed to be biodiversity-friendly, inclusive and resilient.

July 2, 2025After water is diverted for hydropower, rivers are often left with very little streamflow for nature. A new report provides an overview.

June 10, 2025A sudden drop in temperature in Lake Geneva over the Whitsun weekend is leaving swimmers feeling chilly: within a few days, the surface water temperature near the city of Geneva fell by around 8 degrees. This is due to a natural phenomenon that can be observed impressively on the Alplakes platform.

May 13, 2025The year 2024 was very warm and very wet, especially in early summer. This led to a welcome replenishment of groundwater reservoirs and record hydropower production, but also to severe flooding. In Bern, the focus was on the further expansion of hydropower and the pollution of water resources by pesticides and the "eternal chemicals" PFAS.

April 15, 2025To enhance biodiversity in water and on land, we need high-quality, interconnected natural areas. Here the cooperation of different stakeholders is essential.

March 26, 2025Not only are the numbers of species declining, but the composition of species communities is also changing. This is shown by a new study published in the journal “Nature”.

March 11, 2025Storage hydropower plants contribute to the energy transition, but also affect river ecosystems. Sustainable management should not only account for individual hydropeaking events, but also their cumulative effects.

March 6, 2025For a long time, Eawag's research focus was primarily on water quality. Questions relating to hydrology, bed load or flooding tend to be investigated at WSL or ETH. Eawag is now strengthening its expertise in this area. Today, the ETH Board appointed hydrologist Paola Passalacqua as joint professor at the Department of Civil, Environmental and Geomatic Engineering and at Eawag.
