Contemporary food systems have reached a turning point, as they are required to simultaneously ensure food security and minimize the pressure they exert on the environment, aiming to balance human needs and the rhythm of nature. The low efficiency of current models of food production and distribution systems have revealed the need for a major transition toward circular solutions based on resource circulation, local adaptation, and the responsible use of urban spaces. This study explored the integration of circular economy principles with urban agriculture as a new framework for developing resilient, low-emission, and human-centered cities. In addition, a multiscale (micro, midi, and maxi) approach, combined with SWOT, Weighted SWOT, and TOWS analyses, was applied to identify key factors, barriers, and possible directions for implementation and development strategies. The results showed that the greatest potential of these systems lies in the synergy between water and energy recovery and resource efficiency, while energy intensity and regulatory frameworks have remained major challenges. The proposed strategic approach highlights the need to link food production to renewable energy sources, implement simplified evaluation standards (TEA/LCA-lite), and strengthen social acceptance through education and transparency. Circular urban agriculture emerged as a new type of infrastructure, both technological and social, that may become a pillar of sustainable and resilient cities in the future, supporting the achievement of SDGs 11, 12, and 13.
