Our research investigates how the issue of food security is addressed through an effective urban planning strategy and legislative agenda in resource-constrained urban environments. As part of our study, we assess the degree to which urban planners have embraced the issue of food security. We also examine the importance of urban agriculture in facilitating narrower supply chains, which enhance food security. Finally, to further our understanding of the field, this study provides urban farming examples from Canada, Brazil, and Singapore to shed light on how a combination of community and NGOs support, public and private sector investments, as well as specific government regulatory provisions can help alleviate most of the food security challenges that resource-constrained environments present.
