The latest news from Eawag

The implementation of measures to protect biodiversity is lagging behind the targets – which makes it all the more important to plan revitalisation measures as optimally and purposefully as possible, like here on the River Emme near Utzenstorf (Photo: Luftaufnahmen Röthlisberger).
A list of priorities for the protection of biodiversity
July 9, 2024

Biodiversity is dwindling rapidly, while measures to protect it are lagging behind the targets. Only one thing can help: utilising scarce resources as efficiently as possible where they are most effective. The “Lanat-3” research project lays the foundation for this with the help of the latest data and AI-supported models.

Pesticides in water bodies - there is still work to be ...
July 9, 2024

The VSA Water Quality Platform and Eawag have analysed the effects to date of the measures taken under the "Action Plan for Risk Reduction and Sustainable Use of Pesticides" on water quality. The number of limit value exceedances has decreased significantly since 2019. Nevertheless, many kilometres of rivers and streams are still contaminated. Pyrethroids pose a particularly high risk to watercourses.

Presenting the new Eawag publication: Changes in Water

As the Swiss Federal Institute of Aquatic Science and Technology, our research is in the service of society. Discover this for yourself in the new publication.

Our soil consists of several layers. It is porous and loose near the surface, but compact like concrete at depth. Pictured: soil from the boreholes for the necessary groundwater pumps (Photo: Eawag, Joaquin Jimenez-Martinez).
Impact of high-temperature heat storage on groundwater

EPFL has teamed up with three organizations – the Swiss Federal Institute of Aquatic Science and Technology (Eawag), the University of Lausanne (UNIL) and the Association for the Safeguard of Lake Geneva (ASL) – to develop Lémanscope, a citizen-science initiative to monitor the health of Lake Geneva. Today the researchers are calling on volunteers to help collect essential data.

Two international conferences are currently being held at Eawag in Dübendorf: the Global WASH Cluster Meeting and the Emergency Environmental Health Forum. Both are aimed at strengthening and focusing collaboration and international efforts on the topics of water, sanitation and hygiene in a humanitarian context.

Number, size, surroundings and water level: for the first time, there are quantitative scientific recommendations when it comes to the development of new ecological infrastructures for amphibian conservation. A team of researchers from Eawag, WSL and info fauna karch has analysed the optimal conditions for life between water and land.

Three important water stakeholders become a Blue ...
May 15, 2024

The Swiss Water Association (VSA), Eawag and Hunziker Betatech AG HBT recognise water as a public good and a human right, commit to tap water and become a Blue Community. At the same time, Blue Community Switzerland is joining forces with the Solidarit'eau Suisse network and utilising synergies. The VSA now runs the Blue Community Switzerland office together with partners.

Deficits in the ecological state of small Swiss streams
May 6, 2024

A survey of 99 small Swiss streams reveals that the majority of the studied streams have significant deficits in their ecological condition and can only fulfil their function as a habitat for animals to a limited extent. Insect larvae and other small animals that react sensitively to pesticides are missing in over 70% of the streams examined. Statistical analyses indicate that these aquatic organisms are particularly impacted when the structure and morphology of the stream bed has been altered or if the proportion of agricultural land in the catchment area is high.

The risky life of a lake trout
April 22, 2024

Lake trout migrate between different habitats many times over their lives. This helps them grow larger and have more offspring than sedentary trout. However, it also exposes them to dangers – both natural risks and from human intervention in their habitats. To be able to protect them better, researchers from Eawag are investigating the variety and ecological differences of lake trout as part of a nationwide research project in Switzerland.

Impacts of invasive species transcend ecosystem ...
April 4, 2024

Invasive species influence biodiversity across larger spatial extents than previously thought. In a recently published study, researchers from Eawag and the University of Zurich show that the impacts of invasive species extend far beyond the ecosystems they invade and that three mechanisms are primarily responsible for this. These findings are of great importance for the management of ecosystems.

Revision of the Plant Protection Products Ordinance: ...
April 3, 2024

Eawag and the Ecotox Centre welcome a total revision of the Plant Protection Products Ordinance (PPPO). However, the two institutes are calling for improvements on important points, such as the adoption of EU authorisations or the precautionary principle. The ordinance must ensure that other regulations such as the Water Protection or the Environmental Protection Act are not undermined.
