When metropolitan rural spaces appear to be idealized because of the proximity they seem to provide to sustainable food, the aim of this communication is to question the way they are experienced, practised, inhabited through farmers’ food practices. We want to show how farmers’ food practices in metropolitan rural spaces question the paradigm of sustainability. Our hypothesis is the following one: in these spaces, multiples food models are in ‘co-presence’ and in interaction, between the diffusion of urban food models and other food models which seem to be imbued with rurality. To what extent farmer’s food practices are constituent of specific lifestyles and/or of diffusion’s processes of more urban food systems? Do they contribute to reveal inequalities through the paradigm of durability? To answer these questions, we employed self-narratives of farmers living in the French department of Seine-et-Marne localised at the east of the Region Île-de-France. This methodology allows us to understand farmers’ food, professional and personal trajectories and how their food model, which will be qualified, include or not the paradigm of sustainability and for what reasons. Firstly, first surveys show a hybridization of farmers’ food practices in metropolitan rural spaces, between the appropriation of norms of sustainability and reinvention of food knowledges and food cultures. Thus they contribute to reveal farmers’ specific lifestyle in metropolitan rural spaces and new ways of understanding city-countryside links and rurality. Secondly, the paradigm of sustainability seems to question and to transform food practices, which could be unequally appropriate by farmers in metropolitan rural spaces. Thus the emergence of sustainable and alternative food systems could conduct to the marginalization and even exclusion of some spaces and farmers. Complementary surveys are in progress.
