Future climate risks in Switzerland
If risks cumulate – Analysis and management of cumulative climate risks in Switzerland
The Swiss Federal Office for the Environment (FOEN) had conducted eight case studies in Switzerland to assess climate change related risks and opportunities. The synthesis report of these case studies (Köllner et al., 2017) serves as a basis for the further development of the Swiss climate adaptation strategy but also identified knowledge gaps and missing planning tools among others for risks with a very low probability of occurrence and potentially very high impacts for society and/or the environment. Such risks often derive from a combination or cumulation of risks through process chains or from an exceptional accumulation of meteorological extreme events within a short time period.
In order to fill these knowledge gaps, FOEN is funding a new three-year research project, which was launched in spring 2019. It aims at analyzing plausible ‘cumulative’ climate-triggered risks in Switzerland and related management strategies in response to such risks. In a first phase, the project reviews the terminology and available methods for the analyses of cumulative climate-triggered risks. In a next step, the project analyses two related case studies in Switzerland, by including a stakeholder process.
