Abstract

This paper outlines the main data sources and the methodology used to estimate the impact of flood risk in Italy. It assesses the potential physical damage to the housing stock, identifying the main gaps in the current information set. Estimates of exposure and expected annual loss vary greatly depending on the hazard scenarios used, the assumptions about building vulnerability, and the data’s spatial granularity level. Based on our most reliable estimates, the value of homes potentially exposed to flooding is close to €1 trillion (2020 values), about a quarter of the total housing wealth. The resulting expected annual loss can be estimated at around €3 billion.
