March 22, 2021The motto of today’s World Water Day is “Valuing water – What means water to you?”. With this motto, the United Nations wants to raise awareness of the vital importance of water and call on people to think about the value of water. In an interview, Eawag Director Janet Hering explains the importance of water for the aquatic research institute Eawag and also her personally.

February 18, 2021A new simulation study shows that climate change risks significantly altering water temperature, ice cover and mixing of many Swiss lakes. Mid altitude lakes are especially under pressure, running the risk of completely losing ice cover and no longer fully mixing twice per year. Such a change would have fundamental consequences for the functioning of lake ecosystems.

February 12, 2021A community of sulfur bacteria grows in the northern basin of Lake Tanganyika and plays a key role in the lake's nitrogen cycle. With climate change, the deep blooms could expand southward, a new study shows. This could have drastic consequences for regional fisheries. 

January 14, 2021Black soldier fly larvae (BSFL) treatment of organic waste offers a sustainable and economic solution to the need for organic waste management in Indonesia.

November 19, 2020At Eawag, the aquatic research institute, numerous scientists are conducting research into toilets. In short videos, seven of them explain what fascinates them about the topic and what exactly their research is all about.

October 29, 2020When the wind on Lake Biel blows from the south-west and it rains heavily, large quantities of sediment are washed out of the River Aare into the lake. Since the south-west wind also influences the circulation in the lake, the wind direction determines to a large extent where the sediment is deposited in the lake, namely along the eastern shore towards Biel – an important finding for identifying areas at risk of landslides.

October 22, 2020The findings of a new measurement campaign on Lake Kivu in Africa show that, contrary to previous assumptions, the methane concentration in the water is relatively stable or increasing only very slowly. Therefore, the risk of a sudden gas eruption from the lake is currently not increasing.

October 15, 2020Exploration and utilisation of resources from the world’s oceans is not equally distributed across the globe. Although many of these resources originate in the Global South, they are mostly being researched by just a few countries from the North. Accordingly, this is also where most of the benefits and profits are flowing to, despite the Convention on Biological Diversity. This was the finding of an analysis of literature from the last 50 years.

October 1, 2020There are solid psychological explanations for how consistently we follow the behaviour rules to prevent the spread of Coronavirus, such as the expectations we have towards ourselves and others. These are the findings of a representative survey, the results of which can now be used to optimise public information campaigns.

August 28, 2020Nature Sustainability has just published a review article on possible risks that COVID-19 viruses could cause in wastewater. Prof Eberhard Morgenroth (Head of the Eawag Department of Process Engineering) is a co-author of the review. We asked him five questions.
