Food Security and Circular Cities: Paradigmatic Shifts, Geographical and Temporal Scales, and Participatory Governance Support to Facilitate Transitions Towards ‘Urban Sustainability’

This article explores how the principles of circularity, applied to urban food systems, could contribute to catalysing a transition towards more sustainable cities, working on the premise that food security is a key pillar of urban resilience. In order to do so, it critically examines (i) circularity in the context of urban regeneration and why focusing on food could help to understand the sociopolitical and ecological dimensions of circularity; (ii) the geographical and temporal scales of urban circularity; and (iii) how ‘barometers of circularity’ could be built and integrated into participatory urban governance processes to support urban ecological transformations.
