Föhn, climate change and spatial planning

Switzerland has typical winds. The Föhn is a warm and dry wind from the south. The air rises on the south side of the Alps and loses its rain there. On the north side it drops down into the valley and becomes warm. The Bise, on the other hand, is a cold wind from the north-east.

Climate change is clearly noticeable in Switzerland. Temperatures are rising, also in the mountains. That is why the glaciers are melting and getting smaller every year. The forest also suffers from heat and drought. Spruces, for example, need a lot of water. Foresters therefore plant other tree species that tolerate warmth better, for example oaks.

Switzerland is small, and many people want to build. Spatial planning regulates where you may build and where you may not. There are building zones and areas outside the building zones. This protects agricultural land and undeveloped landscapes. The goal is also described as: preventing urban sprawl.

Memory aid: Föhn like the hair dryer (German: Föhn): warm and dry.
