Dry summers: reusing treated wastewater could help
October 17, 2024

With 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.

European streamflow data and where to find it
October 16, 2024

A 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.

Improving fish migration in times of climate change
October 11, 2024

Many 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 3, 2024

Aquatic 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.

A new study led by the Food Packaging Forum provides an overview of chemicals from food contact materials that are present in humans. This research reveals the extent to which chemicals used in food packaging and other food contact articles have been found in human bodies globally, and further highlights significant gaps in Biomonitoring and Toxicity data.

Blue-green biodiversity: recognise, conserve, promote

Biodiversity is not a political programme: Only just 1.6 % of all documents searched at federal level make reference to the term. This is one of the many results that the WSL and Eawag institutes have compiled in the joint research initiative ‘Blue-Green Biodiversity’ and which are being presented today at the Special Info Day to an expert audience from administration, politics, research and practice.
