Challenges to Promote Sustainability in Urban Agriculture Models: A Review

Urban Farm DB summary

Following the PRISMA protocol, a 2023 systematic review evaluated 26 studies on the interplay between urban agriculture (UA) and sustainability surveyed on Web of Science. While UA is increasingly recognized as an action to promote urban sustainability and inform public health policy for urban populations, the review confirms that its implementation still presents challenges in countries across both the Global North and Global South. The review identified numerous key challenges to UA adoption, including air and soil contamination, availability of green areas, layout of urban infrastructure, and food distribution, among others. Given the many socio-economic and environmental contextual factors involved — especially when comparing Global North and Global South realities — the review concludes there is a need to develop a model adaptable to these different contexts. It further concludes that the concept of sustainability lacks a universal understanding, and that one of the most important remaining gaps is addressing social issues in relation to environmental ones.
