30.11.2018 - As an Alpine country, Switzerland has faced the threat of avalanches for centuries. UNESCO has added Switzerland and Austria's management of this natural hazard to its Intangible World Cultural Heritage List. But what is the role of the Federal Office for the Environment (FOEN) in avalanche protection? What is its contribution to this cultural heritage, namely to managing avalanches in order to ensure the safety of the population? And what is the impact of climate warming?
