The latest news from Eawag

Plants and water can mitigate heat in cities. Using Zurich as a case study, Eawag researchers tested a climate model which indicates how large the effect of green and blue spaces is. The model supports urban planning and shows where improvements would be particularly effective.

In view of biodiversity loss, it is important that early-career researchers get involved not only in science but also contribute to biodiversity policy.

Following an in-depth assessment by Health Promotion Switzerland, it is now official: Eawag is a certified ‘Friendly Workspace’. This means that Eawag puts great importance to the health and well-being of its employees.

The near-natural landscaping of the green spaces around the Eawag buildings in Dübendorf not only promotes biodiversity, but also offers employees and visitors an attractive environment in which to spend time. Because of this, Eawag has now been awarded the certificate for near-natural company premises by the Natur & Wirtschaft (Nature & Economy) Foundation. 

Professor Bernhard Truffer of the Eawag Water Research Institute is among the "highly cited researchers 2024".

During ETH Day on 16 November 2024, environmental engineer Valentin Faust was awarded the Otto-Jaag Water Protection Prize for his doctoral thesis. His work provides important insights about the production of fertiliser from human urine.

The 29th United Nations Climate Change Conference (COP29) will take place in Baku, Azerbaijan, from 11 to 22 November 2024. The Aquatic Research Institute Eawag is organising three thematic panel discussions on the topic of ‘Swiss innovations for global climate action’ together with the Institute of Environmental Sciences at the University of Geneva.

Every year, the Hydrobiology Limnology Foundation for Water Research issues an award for dissertations and master theses on limnology. This year, the prize for the dissertation and master thesis went to researchers at the aquatic research institute Eawag.  

A nuclear waste storage facility needs to be secure, even if glaciers were to churn down from the Alps into the midlands in a distant future. This is why Nagra arranged for a study of the sediments that had been deposited in former, deep glacial lakes. The layers are around 600,000 years old, making them much older than the last ice age, which was around 24,000 years ago. Good news for Nagra: it seems that the layers of stone lying beneath have not been eroded by ice since that time.

A new publication by Eawag shows that co-cultures of different microalgae are more resistant to pests than monocultures.

On 1 September 2024, Linda Strande took up her new position as Head of Department at Sandec. She succeeds Christoph Lüthi.

Forest or farmland: The impact on amphipods in the groundwater is detectable, even if the groundwater extraction site is up to one kilometre away.

Insects and spiders are superfoods: rich in essential fatty acids and therefore an important food supply for birds, fish, reptiles, amphibians and small mammals.

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.

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.

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.
