Sfide della rigenerazione urbana

In last decades urban interventions have deeply changed. Contraction in the public sphere, alternation between development and recession, metropolisation, competition and globalization of the markets, are some of the principals chapters of this change. The paper tackles these issues the needs stemming from local contexts, the way they are detected and acknowledged within welfare and urban regulation policies, since long term provisional models are currently denied by new environmental emergencies, immigration, stagflation, and other largely unpredictable circumstances. Public policies are taken into account in the frame of the city as a “collective actor”. Innovation in urban policies, planning and urban design tools is called upon to a strategic approach matching certainty (in times (opp. within a term time) and procedures) and flexibility, resources shortage and multiplicity of actors. Part three deepens some reference cases of urban regeneration tackling different issues, such as: equity, understood as the quality of covenant with citizens; efficiency, framed as a set of conditions that optimize the urban performance; sustainability which conveys morphological and ecological quality of the environment. A major focus pay attention to innovation in governance schemes and in professional skills involved.
