The paper presents a field research on the "Jardins Partagés" (JPs) in Paris. A JP designates a community garden, animated by local associations on small public plots. They are real social and cultural hubs, improving environmental quality and social life. The JP, in an urban high-density City, creates a sort of V-effect used in the Brecht’s theatre to promote social change. Equally, the JPs could suggest scenarios for sustainable futures, promoting a community management of public good.
