Hazard situation and land use

Surface runoff risk map

The new map shows where potential risk from surface runoff exists. It covers the whole of Switzerland, both developed and undeveloped regions, and is publicly accessible online.

Climate change

Are extremes the new normal? In the alpine region, warming has increased about twice as much as the global average since the late 19th century. Switzerland is particularly affected by the impacts of climate change. This affects a wide variety of areas of society and natural and cultural areas in Switzerland. Observations show that climate change is already influencing the natural hazard situation. The Confederation is taking various measures.
