Interest has grown on the agricultural, environmental and socio-political contribution of production farming in long and short food supply chains, family and community gardens, and hobby farms found in and around cities. Agricultural initiatives make up part of the urban experience and urban authorities consider them in their development and planning schemes. The intricacy of the term “urban agriculture” comes from the diversity of its forms and of its representations by stakeholders. A field study conducted in Brittany (France) allows us to assert that in addition to its location close to towns, its urban nature is determined by its purposes and integration at the metropolitan level.
