Food systems and community resilience: a case study of food deserts and centrality of Petrópolis (Rio de Janeiro, Brazil)

Abstract

Abstract Urban and territorial planning play a crucial role in the performance and sustainability of agri-food systems, emphasizing local food production and consumption. This article, based on previous studies of Petrópolis, aims to reevaluate its urban centers, focusing on food and landscape aspects. Through a review of literature on healthy urbanism and agri-food systems, the study incorporates urban cartography developed in Quantum-GIS software, integrating Petrópolis’ territorial and landscape features with comfortable walking and cycling distance. The rural-to-urban transect analysis reveals that rural spaces could be termed as the “periphery of the periphery.” To address decentralization and reduce segregation, comfortable walking and cycling radii—0.75 km in 15 minutes and 3.75 km in 15 minutes, respectively—suggest potential centralities. Implementing measures like expanding street markets and establishing individual points for local farmers to supply natural food can further support decentralization, benefiting public health and food security in vulnerable areas. This approach acknowledges the interdependence between urban and rural areas.
