A multi-stakeholder system for feasibility model of regeneration project with social impact. The field test of Vaiano Valle in Milan

Urban regeneration, as a multidimensional process to enhance built environment, is taking on an increasingly key role in meeting challenges of sustainable and inclusive city development. In Italy, regeneration interventions are increasingly being configured as multi-stakeholder processes. It is outcome of public-private and social private partnership which is carried out through co-design paths that combine actions on built environment - so-called "hardware" component - with actions that affect the "software" component of social infrastructure of cities by activation of welfare services aimed to the city and communities. There is a growing awareness that urban regeneration process that does not intentionally include an investment in social infrastructures and aspirations of citizens, transforming them into social entrepreneurship, will be unlikely to generate and maintain value over time. These "aspirations", which often prove to be the only possible source of value generation, translate into "a new science of understanding and making cities that start from the urban as a lived experience of its citizens" (La Cecla, 2015). The precondition for sustainable and inclusive development of territories lies in the definition of governance systems in which the plurality of stakeholders and assetholders have tools to cooperate and to give back to places a value in use, in order to jointly economic interest and production of social value. In this sense, third sector and cooperatives are strategic allies for Public Administration in pursuit of general interest, both for their aptitude to produce social value and impact, and also, for their statutory mission and ability to intercept need. The paper presents the results of a field test funded by the Ministry of Economic Development, which involved private investor, exponents of cooperative sector and University, to define a feasibility model for urban regeneration with social impact and based on a multi-stakeholder system and the cooperative's value system
