The relationship between food and cities has been recognized as an area of interest for urban planning only recently, thanks to measures adopted at various government levels, locally and internationally. Rethinking the processes of food production, distribution, sale, consumption and recycling in a sustainable and socially equitable way can contribute to making cities fairer, healthier and more resilient to climate change. Starting from these premises, our contribution explores, in particular, the hypothesis that rethinking the relationship between food and urban space can provide an opportunity to promote socio-spatial regeneration processes of public housing neighbourhoods, through projects and actions that involve their inhabitants. This hypothesis is argued starting from a project experience developed in Borgo San Sergio, a district of Trieste, Italy, which aims to consolidate and enhance practices of cultivation and distribution of food, but also of environmental education. The aim of the project is to create a short supply chain in which social agricultural enterprises are involved. The critical reflection stemming from the case study outlines some possible fields of intervention for an urban planning practice aimed at bringing the food system back to an urban and local scale—downscaling—with social and environmental justice goals consistent with the European Green Deal.
