    Physical Planning Implication of Urban Agricultural Practice in Lagos Metropolis.
    (Department of Urban and Regional Planning, Faculty of Enviromental Design and Management. Obafemi Awolowo University., 2023) OLALEYE, Daniel Oluwasola.
    This examined the spatial distribution of urban agriculture practice in Lagos Metropolis; identified and examined the land tenure system in urban agriculture practice; examined the socio-economic profiles of urban agriculture stakeholders; identified and examined the factors influencing urban agriculture practice; identified and examined the impact of urban agricultural practice on residents; and determined the relationship between urban agriculture and physical planning. This was with a view to provide planning policy that will stimulate the growth of urban agriculture. The primary data were obtained through administration of questionnaire on three (3) sets of respondents. These are: farmers, residents and staff of agencies responsible for the control and development of agriculture and its land use in Lagos metropolis. Reconnaissance survey revealed that there are 9186 registered farmers who are into urban agricultural practice in all the relevant local government areas in Lagos metropolis. This figure was made up of farmers involved in the production of five (5) different types of urban agricultural products. These are: flower (160), vegetable (1367), poultry (1640), fishery (2170), and livestock (3849). These 9186 farmers form the population for this study. A total of 243 (10%) farmers were randomly sampled from the sample frame using the already established and identified clusters for each type of agriculture activities in each of the LG area, however only 227 of the questionnaire were used for the analysis in this study. Residents around the clustered farm sites were stratified into three different strata using the distance of buildings from the farm sites. These are: 0-300 metres, 301-600 metres and 601-900 metres. Physical counting revealed that there are 240 streets with 6228 buildings. The study randomly selected 20% of the streets from each stratum. From the selected streets, 20% of buildings were selected, thus a total of 333 were selected. From a selected building, a household head with the longest stay was sampled. Where a household head is not available, the oldest available resident will be chosen in lieu. This study revealed that in Ojo, between 2013 and 2022, the size of vegetable farms decreased from 173.02ha to 156.65ha. Similarly, the number of horticultural gardens in Eti-Osa local government decreased from 63 in 2008 to 28 in 2022. It was further revealed that the officially designated phase II of Fish Farm Estate with a total land mass of about 30ha has been converted to other forms of agricultural by 2022. From the findings, major constraint to UA is access to land. Overall, 17% (39) of farmers own their farmland, nearly two-third (65%) rented the land they are using, while another 15% are squatters. Chi-square statistic indicted that there is relationship between gender of farmers and the type of urban agriculture activities they practice (χ2 =13.684; p=0.008). Findings showed that more residents living within 0-300m distance from the farms complained about farmers’ activities generally as compared to those living outside this radius. This pattern is the same for all types of farming activities in the neighbourhood except horticulture garden. Majority of residents (225/304) were of the opinion that farming and agricultural are appropriate in cities and urban centres. Generally, the study revealed that the most important positive impact of UA as perceived by all residents is enhancement of environmental protection law (PI = 4.89). Representative of Agricultural Land Holdings Authority (ALHA) indicated that there are areas within the metropolis where agriculture activities are officially permitted. The study concluded that urban agriculture has the potential to contribute to local food security by increasing the availability and access to fresh agriculture produce. In the future, the ability of cities to produce at least a portion of their own food supply will become important as a result of changes in several aspects of urban area and its dwellers.
