Specifically the Alps react sensitively to temperature fluctuations. Instabilities in permafrost lead to large-scale erosion of soils and can have threatening impacts for the Alpine population and economy.
Increasing temperatures affect the stability of Alpine permafrost. From the perspective of natural hazards prevention, it is important to know whether permafrost areas (e.g., rock glaciers) are still stable and what kind of hazards could be generated by them in the future. As permafrost areas extend beyond national borders, a coordinated approach on monitoring permafrost areas and potential erosion effects seems adequate.
Common monitoring system: number of Alpine countries which have integrated their permafrost and erosion monitoring systems into the Alpine-wide framework; number of activities, stations and networks included in the stock-taking and mapping
Remote sensing: qualitative description of assessment, with reference to the different Alpine countries and their approaches
The Alps are specifically prone to natural hazards with different scopes, including local events such as avalanches, rockfalls, torrential hazards and landslides as well as larger events like floods. A generally growing population and accumulation of human assets and settlements in hazard-prone areas as well as extreme events tend to increase natural hazard risk. As natural hazards do not stop at regional or national borders, an Alpine-wide common framework to deal with large-scale and potential cross- border impacts is required. Special consideration needs to be given to permafrost areas and potential risks related to permafrost instabilities as well as large-scale flood events with impacts on overall river basins - these natural hazards have the potential to lead to large-scale and cross-border impacts.
