In the context of crises such as the pandemic and the war in Ukraine, local food systems have emerged as a potential solution to the challenges of food sovereignty and sustainability. However, the adoption of local food as a widespread practice remains limited. The aim of this research is to identify the drivers that could lead to the widespread adoption of local food systems as an inclusive practice in urban areas. We adopt a systemic approach to analyze the dynamics of supply systems and communities in a city within the Paris region, combining geographic, ethnographic, and documentary data. Our findings reveal a tentative practice and a gap between the supply and the population’s usage patterns. Our research highlights how food behaviors are embedded within interacting systems. It calls on public authorities to make local food systems a significant focus for large-scale distribution and urges the economic sphere to rethink its business models and value chains.
