Two EPFL students have compared the ability of a forest in Vaud Canton to protect against avalanches before and after it was ravaged by fire in 2018. Their method could be applied to other forested slopes, helping to enhance local reforestation strategies. Widespread drying as a result of climate change is driving an increase in forest fires around the world. By the end of the 21st century, Switzerland is expected to experience many more fires between May and November than it does today. According to experts, the worst-affected areas will be the Aare valley and lowland areas of Bern Canton. Moderate increases are predicted in Ticino Canton and the Engadin, while larger areas of Valais Canton will likely be set ablaze. These fires could trigger erosion and compromise the protective role played by forests.
