Agricultura urbana e Segurança Alimentar e Nutricional

Urban Farm DB summary

A systematic review using the Scielo database to examine the relationship between urban agriculture (UA) and food and nutrition security (SAN) in Latin America. A search for "agricultura urbana" returned 156 articles; screening by title and keywords narrowed this to 32, and excluding non-Latin-American studies left 26 articles connecting UA and SAN to some degree. Only 5 of these made a direct link between SAN and UA; the rest addressed only some dimension of the concept, and the review found no concrete, agreed definition of UA across the literature. Few studies treated the urban farmer or production scale as central to promoting SAN, despite UA's role in food-sovereignty practices such as seed exchange and preserving planting traditions. Most of the reviewed studies pointed to significant problems, including contamination of crops by heavy metals, difficulty achieving environmental, social and economic sustainability — particularly for farmers who end up working in other sectors — and a lack of technical assistance.
