PROWD has the purpose of re-conceptualising the 15mC through “non-standardised” solutions in Low-Density Urban Areas (LDUA) of metropolitan contexts. PROWD proposes a change of perspective, with a focus on niche initiatives. Starting from a critical review, PROWD tests transition pathways in the outskirts of three capital cities, by organising local co-design workshops with resident and stakeholders, aimed at the collective interpretation of ongoing and potential initiatives providing innovation in public services, proximity trade and mobility. This emerging strategic knowledge, including self-organised citizen interventions, urban policies, and social entrepreneurship, will be the main content of “collaborative pacts” between local administrations and the stakeholders engaged in the co-design.
