Fieldwork on Lake Victoria
May 2, 2017

A conflict is developing in Africa’s Lake Victoria between fish farming in cages and the “normal” fishing industry. Added to that are other factors such as invasive species, wastewater pollution, pesticides and dam construction are putting the unique ecosystem under increasing pressure.  Read more

Changing people’s behaviour is no easy matter. Having developed a method that has been shown to promote behaviour change, Hans-Joachim Mosler of Eawag’s Environmental Social Sciences department has now set up a consulting firm – attracting considerable interest among development cooperation professionals in particular.  Read more

Urban water management 4.0 on World Water Day
March 22, 2017

The future of urban water management is also our future – this was the opinion of seven PhD students from Eawag came to, who decided to write a paper on the subject.  Read more

The water footprint indicates how much water is used to produce consumer goods. A study by Eawag scientists shows that there is a need for standardization in assessments of the grey water component. Comparability is impaired, for example, by the use of different water quality standards.  Read more

As a result of climate change, concentrations of the trace element selenium in soils are likely to decrease. Because the selenium content of crops may also be reduced, the risk of selenium deficiency could be increased in many regions of the world. This was shown by a recent study which used data-mining to model the global distribution of selenium. Read more

Biodiversity can promote ecosystem efficiency
February 16, 2017

Humans influence evolution. In the case of whitefish in Swiss lakes, one consequence of this is replacement of a diversity of specialised species by fewer generalists. A recent analysis now suggests that communities of diverse specialists utilise trophic resources more efficiently. Read more

The “Regional Water Supply for Basel-Landschaft 21” project, which was started in 2013, culminated today in a media conference in Liestal. Read more

Maldi-MSI imaging method visualises cocaine accumulation in zebrafish.
September 29, 2016

A study by Eawag and Zurich University researchers using a new imaging method has revealed that, surprisingly, cocaine accumulates in the eyes of zebrafish. The findings indicate that chemicals – especially psychoactive drugs – need to be assessed quite differently with waterborne exposure than, for example, when pharmaceutical substances are tested in mice. In particular, the uptake mechanisms and effects of cocaine in fish cannot simply be transferred to mammals or humans. Read more

Switzerland’s lakes are not only diverse ecosystems, but also recreation sites, fishing grounds and energy sources. At this year’s Info Day, the tensions between these competing interests were explored. It was concluded that sustainable management calls for an understanding of the complex interactions occurring in lakes – which in turn requires scientific data and appropriate methods of observation.

August 17, 2016

Political actors tend to perceive their opponents as more influential than they really are, and to overestimate the differences between opposing groups. As a result, policy‑making and the search for feasible compromises become more difficult. This phenomenon, as Eawag political scientists have now shown, is apparent even in a consensus-based democracy like Switzerland. Read more
