National water policy needed to cope with global warming
Switzerland’s water sector is not properly equipped to deal with climate change, warns a government-backed study by the Swiss National Science Foundation. The report recommends developing a national water strategy.

According to the foundation, which presented the results on Tuesday, the sustainable management of water in Switzerland is increasingly about how to overcome conflicts of use and interest. A national water strategy is therefore needed to bring together all concerned parties.
Climate change is expected to affect mainly high-mountain regions in Switzerland. Rising temperatures will in the long term lead to a 90% reduction in glaciers and lead to violent flooding, scientists warn.
Launched in 2008, the National Research Programme called “Sustainable Water Management” included 16 projects involving 150 researchers. The budget was CHF12 million ($12.5 million).
Coordination needed
Scientists say Swiss communities and cantons lack strategic priorities and proper coordination. When granting water concessions, mountain regions should be much more attentive to sustainability questions, they add.
Rolf Weingartner of the University of Bern led a project involving 11 communities in canton Valais.
“Socio-economic development has a greater influence on water management than climate change,” said Weingartner at a conference held in Bern on Tuesday to mark the research programme’s conclusion. He cited the demand for artificial snow and golf courses in addition to drinking water.
But if regional collaboration is improved, in future Switzerland will have sufficient water, the scientists believe.
“There should be enough water in 2050, but sewage and access issues need attention,” Weingartner said.
Switzerland is known as the “water tower of Europe”, providing around 6% of the continent’s freshwater resources.

“It’s incredibly arrogant to believe that humans can influence the climate,” says Werner Munter, a world-renowned expert on avalanches. The 73-year-old from Bern is not a climatologist, but over the past three years he says he has read some 20 books and hundreds of scientific studies on the issue. “Nowhere have I been able to…

Whereas rivers in France and Austria are generally clean, rivers in Switzerland have been given poor marks in a study by WWF Austria and conducted by the University of Natural Resources and Life Sciences in Vienna.
No other alpine country uses its rivers as intensively as Switzerland, which has around 1,500 power plants and 150,000 artificial weirs, the environmental organisation reported on Monday. This has an effect on flora and fauna.
“Intact rivers, streams, wetlands and flood plains provide us with clean water and vital flood protection,” said Christopher Bonzi, head of WWF Switzerland’s water programme. “We can’t consider them only as energy providers.”
But in Switzerland, protection of the remaining natural waterways is less strict than in the European Union. WWF Switzerland criticised the fact that whereas the EU explicitly forbids deterioration of valuable bodies of water, Switzerland financially supports small hydropower projects.
According to the study, only one in ten rivers in the entire alpine region fulfils its role as an area for relaxation, a reservoir of drinking water and natural protection against flooding. Out of around 22,000km, 6,500km of rivers are dammed, diverted or forced into concrete beds.
The study looked at all rivers in Austria, Italy, Slovenia, France, Germany and Switzerland with a catchment area of more than ten square kilometres and their tributaries – a total of 57,000km.
WWF’s goal is to set up areas in these countries where the use of rivers for production of power and other infrastructure projects would be taboo.
