As water scarcity is becoming a concern in the Alps and in the lowland areas that receive Alpine water, it is increasingly urgent for the countries of the region to define common strategies to act on this issue. To contribute to this process, ADO set up a drought observatory based on a combination of meteorological information and hydrological indices and data, including, for instance, figures on snow cover and soil moisture. Alpine local and regional governments could benefit from this approach, as they improved the efficiency of their drought management and their ability to face related risks.
