About the Cover

This study analyzed the magnitude and patterns of urban expansion (built-up area) in Ibadan peri-urban areas (Akinyele, Egbeda, Ido and Oluyole Local Government Areas) between 1986 to 2019 using Landsat-5 (TM) and Landsat-8 (OLI/TIRS) images. Across the study areas, our results, on the one hand, show an increase in the built-up area, rock and bare soil, and grassland area, while, on the other hand, they reveal a decrease in forest and open space over the study period. Respectively, the built-up area increased by 306.34%, 317.16%, 243.66% and 400.80% in Akinyele, Ido, Egbeda and Oluyole Local Government Areas. Having established built-up expansion in Ibadan peri-urban areas, this study; however, recommends that comprehensive planning focus on the peri-urban areas is required to arrest urban sprawl and its corresponding adverse impacts.
