The COVID-19 pandemic unveiled the fragility of food sovereignty in cities and confirmed the close connection urban dwellers have with food. Although the pandemic was not responsible for a systemic failure, it suggested how citizens would accept and indeed support a transition toward more localized food production systems.
Housing estates, that is, mass social housing on middle‐ and high‐rise apartment blocks, in urban areas are found all over the world with very similar constructive patterns and a multiplicity of environmental and socio‐economic problems. Boosting new urban spaces of resource production involves citizens in sites which face social and economic needs.

Especially relevant are nitrogen (N) and phosphorus (P), due to their contribution to marine and freshwater eutrophication.
