A methodological approach for the definition of multi-risk maps at regional level: first application

Technological and natural disasters occurred in Europe during last decades showed an increased vulnerability of our society to different risks. Authorities and civil protection need instruments which allow having a better understanding of the variety of risks over a territory and help them in managing the resources and planning the emergency. However, many difficulties arise in comparing hazards, vulnerabilities and risks among them. The existing risk mapping in European countries often allows a simplified comparison of risks by means of potential damages but does not permit any qualitative assessment of multi-risk situations. The aim of this project carried out for the Piedmont Region (Italy) is the development of a decision support system based on a multi-risk approach which can overcome difficulties in the overall risk assessment over a territory. To define multi-risk maps, a multi-risk perspective and stakeholder's perceptions were integrated to a classical risk assessment frame. The specific purpose of this work is describing the methodological framework built up at this stage of the project and discussing the first results.
