October 22, 2024Forest or farmland: The impact on amphipods in the groundwater is detectable, even if the groundwater extraction site is up to one kilometre away.
October 17, 2024Insects and spiders are superfoods: rich in essential fatty acids and therefore an important food supply for birds, fish, reptiles, amphibians and small mammals.
October 17, 2024With climate change, hot and dry summers are becoming more frequent, causing water shortages in some regions of Switzerland. Reusing treated wastewater could help to solve this problem. This has been demonstrated by an Eawag team on behalf of the FOEN and some cantons. The researchers also explain what still needs to be done to put the option into practice.
October 16, 2024A new catalogue and database of over 17,000 European river catchments facilitates the work of researchers in the field of hydrology. The EStreams project, carried out at Eawag, provides hydrological and meteorological data as well as information on the landscape of the river regions. The records go back up to 120 years.
October 11, 2024Many fish species migrate back and forth between habitats in the course of their lives. However, man-made obstacles make life difficult for these species. Cold-loving fish are also affected by climate change, especially if access to cold-water zones is made more difficult. Renaturalisation can solve this problem. An Eawag project will now help to identify obstacles and remaining cold-water zones so that restoration measures can be planned in a more targeted manner.
October 11, 2024The Swiss fisheries advisory office (FIBER) promotes sustainable fisheries through advice and training. It now has a location in French-speaking Switzerland.
October 10, 2024Combined sewer overflows following heavy rainfall could be avoided through the use of Blue-Green Infrastructure, such as infiltration basins, retention ponds, and porous pavements.
October 10, 2024Members of Eawag's Sandec Department helped organise and participated in the recent Water for Impact (TU Delft) x Eawag Sandec Exchange Day. The aim of the Exchange Day was to enhance mutual understanding of each group’s work, facilitate knowledge exchange, and initiate collaborative efforts for future projects and research.
October 3, 2024Aquatic invertebrates are used as bioindicators to evaluate the quality of Swiss watercourses. However, climate change is also leading to changes in the species composition of these organisms. Eawag has now investigated the impacts of increasing temperatures on water body evaluations on behalf of the FOEN. The findings: the indicators are expected to remain relevant at least for the coming decades.
