Review of Urban Agriculture Practice to Enhance Food Security in Nigeria: Significance of Geospatial Technology

In low-and middle-income countries, the rapid urbanisation poses a significant challenge to food security and nutrition for their inhabitants.Urban poverty is a global issue and is particularly noticeable in Africa, where 61 per cent of urban residents live in slums.Urban poverty is caused by several factors, including structural adjustment programmes, low salaries, unemployment, and the general economic crisis that nations like Nigeria are experiencing.For this reason, policymakers find it important to guarantee food security in the city.Undoubtedly, it is optimal to view food security as a causal, interconnected chain that spans multiple domains, from production to processing, consumption, and distribution.Urban agriculture is a key strategy for ensuring food security in urban areas.Thus, this paper aims to review urban agriculture practice to improve food security in Nigeria, emphasising the importance of geospatial technology.The study focused on the opportunities and challenges of urban agriculture in Nigeria.The findings showed that many city dwellers are drawn to urban farming to obtain food, cash, and other necessities for their homes due to the growing demand for jobs and sustenance among urban dwellers.However, Nigeria's urban agriculture industry faces numerous obstacles, such as unstable land tenure, a lack of government support, limited market accessibility, restricted access to factors that contribute to productivity, and inequality concerns.
