Impact of urban farming on health: a systematic review

Abstract

Background Urban farms are spaces designated for the cultivation of plants for food security, medicinal and curative purposes. Since the turn of the century, they have become more widespread and health benefits have been claimed; however, no consensus exists regarding this information. Hence, this study aims to provide information about the health effects of urban farming. Methods Protocol register number CRD42023448001. We followed the guidelines of Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Studies addressing urban farming interventions in any population group were included without age limitation of publication from PubMed, DOAJ, CAB s and NIH. Risk of bias was assessed using the Risk of Bias In Non-randomized Studies - of Interventions tool, and data were narratively synthesized. Results The search retrieved 2578 manuscripts, reduced to seven after screening. Urban farming’s impact on health has been reflected in the physical domain by increasing self-reported health levels, physical activity, perceived general health, healthy eating and decreasing drug use. Parasites’ presence has also been reported. In the mental aspect, urban farming is associated with relaxation and stress reduction. From a social perspective, urban farms provide a sense of belonging, personal growth and happiness. Conclusions The benefits of urban farming outweigh the disadvantages. Further research should be conducted to clarify the potential benefits of this practice.
