An Evaluation of the Spatial Extent of Urban Farming and Its Potential on Food Security in Lagos Metropolis, Nigeria

Abstract

This study investigates urban farming dynamics and its potential for food security in Alimosho, Ifako-Ijaiye, and Ikeja local government areas of Lagos State, Nigeria. An analysis of the land cover map for 2023 revealed that built-up areas accounted for 188.31 km² (71.59%); farmlands covered an area of 49.46 km² (18.8%); grasslands covered an area of 7.87 km² (2.99%); thick vegetation covered 17.2 km² (1.52%); while water bodies covered an area of 0.29 km² (0.11%). Farmlands is primarily concentrated in Alimosho, highlighting the tension between urban development and agricultural land use. The presence of grassland and thick vegetation, especially in Ikeja, although minimal, plays a crucial role in biodiversity and ecosystem services. Survey results indicate a high level of awareness regarding urban farming activities, with 84.88% of the respondents being somewhat or very aware. The overall food security situation appears predominantly secure, with 59.02% feeling somewhat secure, although 24.63% remain neutral about their status. Perceptions of food availability are positive, with 87.56% rating locally produced food as good to excellent. Despite this, many respondents experience frequent food shortages, with 63.42% sometimes reducing meal sizes. A significant 73.42% of respondents believe urban farming positively impacts food security, citing increased local food production (58.80%) and better availability of fresh produce (33.55%) as key benefits. These findings emphasize the potential of urban farming to enhance food security in densely populated urban areas, while also indicating the need for improved consistency in food availability. Thus, this research highlights the critical role of urban agriculture in addressing food security challenges amidst ongoing urbanization in Lagos State.
