摘要:Urban transformations depend on the uses of the city by “old” and new citizens (residents, workers, migrants, refugees, students, seasonal, homeless individuals, tourists, city-users, commuters), and on their relation within urban spaces and resources, triggering regenerative opportunities, networking and empowerment processes. Considering the city and its heritage as a common good, in which each citizen could access and play for the knowledge, management, conservation and transformation of urban contexts, the contribute illustrates the results of experimental actions in Bologna (IT) finalized to test new stakeholder engagement processes and to develop new tools for participatory practices and new productions for the reactivation of the city. In the last years Bologna represents a field of experimentation for different forms of collaborative approaches with the aim to test and innovate tools and policies for the public space. The paper presents the results of specific projects linked to EU funding schemes (ROCK project) and local multi-stakeholder initiatives, such as the Bologna Design Week, which are part of the research and experimentation carried out by the research unit team. This article illustrates a model to improve the regenerative capacities of the city, by reinforcing local identity and culture, fostering participation through active engagement of all relevant stakeholders, allowing a diversity of responses of groups of actors with different roles and different strengths.
