Cambiamento climatici e fragilità territoriali. Le sfide per un nuovo welfare urbano

The big impact of human activity on the environment, which has taken place in recent decades, has contributed to determining the crisis dimension that characterizes contemporary territories, which are increasingly defined as "fragile". Human beings have so deeply and irreversibly modified the territory that many scientists are used to define our geological era with the name of "Anthropocene", to arrive to the most recent theories of the so-called "Neo-Anthropocene", according to which man, once understood his responsibility regarding these changes, puts in place a resilient urban development, exploiting his creativity in order to reverse his role: from the main cause to the architect of a new rebirth. The contribution is a part of the reflections specifically referring to the forecasts for sea-level rise as one of the effects of the ongoing climate changes and the direct consequences of the phenomenon on coastal cities, also in terms of urban welfare, manifesting the urgent need to adapt the urban form to the environmental context of reference through reconfiguration actions of the morphological components which consider flexibility and diversity as priority elements, to pursue a sustainable social and economic development. Therefore, the urban regeneration strategy to be adopted in such contexts must be aimed at mitigating the effects of climate change, to restore a renewed perception of safety to the territories affected by these emergency events. Is about adopting a methodological approach that is able to direct a resilient urban development, calling into question the limits of the current urban forms and favouring an overcoming of the sectorial approach to urban complexity in favour of an integrated one.
