Nuovi scenari di rigenerazione urbana per le città dello Stretto nell’emergenza pandemia

The resumption of investments for a new vitality of territories and urban areas due to the pandemic state of emergency will look at the synergistic integration of urban regeneration and development policies with investments in infrastructures at all levels of scale. Everything will be played on the synergy and synchrony, of actions, policies - their implementation, management - and the economic effects of the strategies implemented. It will be necessary to identify the “priority” urban areas on which to concentrate investments and the “sectors”, or rather the systems, which better condense and dissipate energy and efforts, producing positive effects on the territory, in terms of relaunch, attractiveness and ecological environmental balance. It will be necessary to identify the strategic, active, propulsive areas. The highest level of synchro-modality is within the so-called daily urban systems. In these systems, mobility enables networks of different infrastructures and a variety of multimodal nodes, of emitting centers of human activities; it intercepts flows but also unresolved issues, in terms of risk, of infrastructural and economic gap. The Strait Area, which is in fact a daily urban system, lends itself to experimentation with a new model of resilient, smart and “fast” cities. This is understood as the ability of territories and urban organisms to respond to external solicitations by absorbing them and restoring their functions in the shortest possible time; for cities, it means being ready for the future, changing by adapting their resources to face the new challenges that arise. It means guaranteeing territorial continuity (land-sea) and short times for the city, maximum 30 minutes. The paper will analyze the “daily urban system” thus delineated, in relation to its functioning and the condition of “resilience”. The complex nature of the hydraulic and hydrogeological problems and the balance of the last decades therefore highlight the vulnerability of a territory on which inappropriate intervention has been carried out more frequently and extensively than necessary. In this context, the awareness of natural risk and the adoption of defense measures more than ever a rational and multidisciplinary approach, aimed at the ecological-environmental balance of natural and anthropic systems.
