Risk management and land use planning for environmental and asset protection purposes
In Italy, territorial risks and emergencies are managed in completely separate sectorial plans; this approach does not consider the interactions between risks, and could decrease the efficiency of the planning and emergency actions.
Therefore, the research presented 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 research is focused on a local scale, because in Italy the Municipalities are in charge both for the direct interventions on the territory and emergency planning.
Each step of the methodology is accompanied by a GIS Map, which helps to spatially understand the extension and gravity of each risk.
The proposed methodology is based on a semi-quantitative approach: a simple rating scale (from 1 to 1,99 low, from 2 to 2,99 Moderate, from 3 to 4 High) is employed to evaluate all the main risks encountered in a municipal territory.
The collected information about each risk is described through three different categories: the local riskiness (LR), the protection measures (PM), and the historical events (HE), which depend on the local characteristics of the risk.
After the categorization, each risk category is rated using the common scale. When some areas are interested by overlaid risks, the values assigned to LR, HE, PM are used to estimate the value of the possible interaction through a simple weighted average, where: LR = weight 1, HE = weight 2, PM = weight 0,5.
After assessing the interactions, the proposed methodology particularly focuses on the Seveso industries, in order to verify the consequences corresponding to the obtained value of interaction.
