Making the shift from global to territorial food systems is critical for sustainability and demands transformative, coherent, and integrated land and food policies. However, how policy integration may be achieved or hindered remains unclear, particularly in the case of coexisting agri-food models. The coexistence of conflicting models, such as specialization versus diversification and agro-industrial versus ecological practices, entails power relations that significantly influence the political agenda. Drawing on semi-structured interviews and document analysis, we focus on land-use planning and local food policies to examine how policy integration is shaped by, and reshapes, power relations in the context of coexisting agri-food models in a sample of case studies in France. Our findings show that policy integration occurs with innovative initiatives at the stage where territorial agriculture is assessed, strategies are determined, and policy instruments designed. Integration is, however, constrained by unbalanced power relations, which restrict land-based policy interventions that seek to transform food systems. Local authorities exercise caution when applying these interventions, seeking to involve major farmers’ organizations while mitigating contentions. The policy integration process reshapes power relations, empowering alternative minority agri-food professionals through greater influence in the political arena. This process also helps local authorities to acquire legitimacy in agri-food matters. As one of the first studies to offer empirical evidence about land and food policy integration, this article provides insights for policymaking in terms of the crafting of enabling institutional contexts for the transformation of territorial food systems. Future research is suggested to explore contextual influences and power dynamics in policy implementation.
