LUP and multi-risk: The mutual influence of natural and anthropic impacts

In Italy, the different territorial risks are managed through completely separate plans, that the Municipalities (local scale) should apply on their territory with direct interventions; anyway, the current approach, which does not consider the interactions between risks, could decrease the efficiency of the planning and emergency actions. Therefore, the research here exposed, deriving from a PhD thesis, aimed at developing a quick and easy to use methodology, able to identify and rate the main risks which characterize a territory, and to simulate the possible effects of their interaction on the territorial and environmental vulnerabilities. The methodology was tested on the case study of Mantua, where both industrial, seismic and hydrogeological risks are present. Each step of the methodology proceeds simultaneously with a GIS Map, which helps to spatially understand the extension and gravity of each risk.
