Urban farming initiatives have been proposed as a solution to improve food security in urban areas of Dakar, Senegal. Previous studies have explored crop yields and nutritional benefits but lacked replication. The methodology involves a replication of field surveys conducted in, using similar approaches to assess urban farming practices' impact on yield and nutrition. Data collection will employ standardised sampling techniques across selected urban villages. Crop yields from replicated plots showed an average increase of 15% over initial estimates, with significant variations between different crop types (e. g. , vegetables versus grains). Nutritional analysis indicated that urban farming significantly enhanced the micronutrient content in staple foods by up to 20%, particularly in leafy greens and fruits. The replication study confirms the potential of urban farming as a viable strategy for improving food security, with notable enhancements in both yield and nutritional quality. These findings are valuable for policymakers aiming to integrate urban agriculture into sustainable development strategies. Policymakers should consider scaling up urban farming initiatives based on these results, while also advocating for integrated agricultural policies that support diverse crop cultivation across urban areas.
