Urban resilience and anthropic risks. The case of the Polcevera Valley in Genoa

WithS. Candia, F. Pirlone, I. Spadaro, A.C. Taramasso

The research shows a methodological approach aimed at making urban spaces more resilient towards an external risk. To define the resilience of an urban system/space, it is necessary to assess the pre-event and after-event status. The resilience level is calculated on the basis of these two values. This is possible by dividing the system into macro-sectors and actors involved. In the literature there are several examples to evaluate urban resilience. This paper attempts to develop a resilience index using an actors/actions analysis. Indeed, it is possible to increase the threshold of resilience of the perturbed system by acting on each macro-sector, as a result of the implementation of a specific action by a determined actor. The authors consider as actors the components of the ‘Quadruple Helix’: universities, industry, governement and civil society. This methodological approach is applied to a case study: the Polcevera Valley (Genoa) after the Morandi Bridge collapse.
