Recent literature has pointed to the role of urban agriculture in self‐empowerment and learning, and in constituting ways to achieve food justice. Building on this work the paper looks at the potential and constraints for overcoming the residual and contingent status of urban agriculture. The first part of the paper aims to expand traditional class/race/ethnicity discussions and to reflect on global, cultural, procedural, capability, distributional and socio‐environmental forms of injustice that unfold in the different stages of urban food production. The second part reflects on how to bring forward food justice and build a politics of engagement, capability and empowerment. Three interlinked strategies for action are presented: (1) enhancing the reflexivity and cohesion of the urban food movement by articulating a challenge to neoliberal urbanism; (2) converging urban and agrarian food justice struggles by shaping urban agroecology; and (3) regaining control over social reproduction by engaging with food commoning.
