Geo-Spatial Assessment of Masterplan Alteration of Ibeju-Lekki Area of Lagos State

Abstract

Context and Background The master plan of Ibeju-Lekki, developed in 2009, aims to conserve the environment, control urban sprawl, reduce transportation expenses, avoid land use disputes, and minimize pollution exposure. However, inadequate planning has led to the growth of urban sprawl in the area, causing flood and erosion hazards in some communities. Goal and Objectives: This study aimed to assess the spatial distribution of land use types in the master plan, determine the land cover change between the year of master plan production and the present year, and assess the development of Ibeju-Lekki in relation to the master plan. Methodology: The analogue format of the master plan was obtained, georeferenced, and converted into a vector format (ESRI Shapefile) for spatial analysis. Multi-spectral images (Landsat images) were obtained for the years 2009 and 2023 to detect changes in land cover and development in the study area. Results: The results showed that residential land use had the largest spatial extent on the master plan, but it will soon be congested due to increased industries. Built-up areas, bare land, and wetlands increased between 2009 and 2023, while vegetation and water bodies declined. The highest development occurred on residential land use between 2009 and 2023, with unplanned development in fragile and conserved areas like lagoons, green areas, flood basins, open space, and eco-tourism. The study recommends vulnerability assessment of altered areas in the master plan and re-evaluation to accommodate the changes occurring in the Ibeju-Lekki area of Lagos State.
