Sustainability transformations are spatially situated and dependent on the contexts in which they take place. The French concept of territoire makes it possible to analyze, situate and politicize transformation processes more systematically, paying attention to relations of interdependence and conflict between groups. In this study, we use the multidimensional conceptual framework of territorial transformations (Pachoud et al., 2022), to analyze the transformation dynamics of agri-food systems in the Coeur des Bauges and the Galaure valley, in France. Through a qualitative analysis, the territorial approach first enabled to describe the different dominant and alternative territorialities linked to the agri-food system in the two territoires studied, in their material, ideal and institutional dimensions. In addition, the territorial approach highlighted the interdependent relationships between the different groups, as well as the tensions and conflicts underlying the different power relationships. The comparative analysis demonstrated the ability of different groups to develop interdependency relationships to ensure food production in the territoires and to deal with conflict situations, linked to land sharing and divergent imaginaries. Such interactions between the different groups allow learning and sustainable transformations of agriculture and food.
