Civic food networks (CFNs) have long recognised the connection between reducing unequal power relations (starting with gender, race and class) and improving more democratic (i.e. just) access to healthy and affordable food. This chapter connects theories of justice with empirical research exploring how place-based civic food actors in Australia envision and work towards transformative food systems change, revealing how an eco-social contract can be extended through the principles and practices of food justice. Findings identify four principles for eco-social food justice that aim to address unequal power relations based on rights for all, resilience, intersectional solidarity, and ‘food as commons’ concepts. In shifting away from mainstream food security framings, these civic visions represent a rich source of learning about how to progress from reformist food policymaking towards more radical, eco-social solutions based on equity, human rights, ecological health and systems change.
