Urban areas are increasingly adopting the tool of urban food policies (UFPs) to address food-related challenges, especially for a sustainable transition of their food systems (FS). Indeed, FS were assessed to have a great environmental impact, and cities are recognized as privileged actors to address this challenge. More recently, the problem of justice in such transition was raised. One dimension of vulnerability proven to crosscut all FS stages, and to increase exposure to climate change effects, is gender. However, literature on just food transition and UFPs does not seem to always consider this dimension of potential vulnerability. This paper firstly elaborates on the concept of “just food transition” (JFT), then presents relevant literature on gender differences in FS to argue that interventions aimed at JFT should apply gender mainstreaming. Later, it analyzes twenty relevant cases of UFPs to assess whether they consider gender differences, with the aim of demonstrating that, although theory seems to prove its relevance, a gender mainstreaming approach is still widely lacking from policy practice and rather some policies risk to reinforce existing gender stereotypes related to the FS. The paper ends with conclusions and suggestions for further research.
