This chapter presents three Italian case studies: Custody of the territory in Tuscany, a community garden in Campania, and mountain pastures in Aosta Valley. The “Custody of the Territory” is a local project implemented by a local government agency which has an agreement with local farmers concerning environmental services to increase resilience to flooding, and to improve the landscape and hydro-geological management. The second case study focuses on a community garden in the Campania region, a collaborative green space converted from a degraded site into an eco-archaeological park. The third case study describes the collective management of mountain meadows and pastures in the Aosta Valley region, where regional support ensures the co-ordinated action of several stakeholders, maintains landscape and preserves biodiversity. Following a brief description of the case studies, the agri-environmental public goods provided by collective action, the factors affecting outcomes in collective action and the policy measures in support of collective action are discussed.
