摘要：This study examines urban spatial change in land use and land cover of Ibadan Northwest Local Government Area (LGA)in Oyo State. The general patterns of land use/cover as they were recorded in remotely sensed data were analysed. Multidatesatellite imageries (Landsat ETM+ 2000, Landsat ETM+ 2014 of 30m spatial resolution respectively were obtainedand used for the study. These images were enhanced, geo-referenced and classified using IDRISI software. The result ofground truthing was combined with visual image interpretation as training sites for supervised classification. To predictland use land cover change of the area in the next 7 years, CA-Markov chain analysis, a land cover prediction procedurewas introduced. The results showed that the natural environments (vegetation, wetland, water bodies, forest, grassland andbuilt-up) were being threatened, as they reduced continually in the area extent over time and space while the socialenvironment (built up area) expanded and this may likely be the trend between 2000 and 2021 as projected. The studydiscovered that urbanization processes is majorly responsible for land-use/land-cover change in Ibadan North-west. Inconclusion, the study advanced our frontier of knowledge on land use/cover study by providing information on the statusof natural and social environment in Ibadan North-west, between 2000 and 2021 using remotely sensed images andGeographic Information Systems (GIS) technology.
