All over the world, different forms of urban food gardens (family gardens, school gardens, community gardens, allotment gardens, and so on) are flourishing. These initiatives vary in terms of space, actors, functions, and forms of organization. This article explores community garden typologies, focusing on Incredible Edible (IE) initiatives. We propose a theoretical discussion of IE initiatives and the differential adaptation of this model in contrasting contexts, specifically the city of Rennes, in France, and the city of Montreal, in Canada. The investigation of IE in both case studies is predicated on a qualitative methodological approach. A key conclusion is that the IE movement survives largely because of the input of volunteers. However, its longer-term sustainability requires resources and investment from municipal institutions if a real transition to edible cities is to be attained.
