Extreme hydrological events, such as those which recently occurred in Austria, Switzerland and Germany have focused the attention of the European community on the vulnerability to natural hazards. In the same time, in recent years risk governance and policies throughout Europe are changing the role of the state and individual responsibilities for risk management and precaution. The new policy agenda is to enhance the responsibilities of local authorities and private citizens in mountain hazards. The project aims to developing and experimentally analysing new arrangements of responsibility sharing for the management of natural hazards in mountain regions.
