Résumé : Studying urban food innovations impact on ecological transition, implies to analyse their scaling capacity. The ability of singular initiatives to contribute to the ecological transition is indeed weak if they are not likely to be replicated, imitated, amplified, supported. How do these initiatives disseminate contributing to the transformation of food systems, in particular at the territorial level? This paper addresses this question through two case studies from the URBAL project in Montpellier: a cooperative supermarket and the municipal school catering improvement programme. It particularly focuses on the interest of a territorial anchoring of the three forms of scaling (scaling up, out and deep).
