Food policies are receiving increasing interest for a variety of reasons, related to the role of food and food-systems in some major challenges, from climate change to social justice, human and animal health and welfare, and the sustainability of land and urban systems. This contribution proposes to analyse and interpret this process, in a multi and transcalar perspective, by juxtaposing and integrating geographical perspectives with those of other disciplines (economics, law, political science), and reading narratives and spaces involved in the construction of food policy. While adopting the mobility of policies as an interpretative key, the article analyses and reconstructs the main narratives caracterising global, national, regional, local and urban food policies.
