Analyzing Urban Sprawl in Okene using Remote Sensing Techniques

Abstract

Urbanization, a global phenomenon, profoundly impacts human habitation, leading to environmental and socioeconomic changes. In Okene, Nigeria, rapid urbanization has resulted in unchecked urban sprawl, driven by factors such as population growth, housing construction, and deforestation. This research aims to analyze urban sprawl in Okene using remote sensing techniques, focusing on its extent, drivers, and impacts, to inform sustainable urban planning strategies. Remote sensing data from Landsat satellites were utilized to analyze land cover changes between 1991 and 2021. Spatial analysis techniques, including supervised classification and change detection, were employed to determine the extent and rate of urban sprawl. The study revealed a significant increase in the built-up area, with urban land expanding from 1.86% to 4.57%. Urban sprawl occurred at an annual rate of 19.94% between 1991 and 2001, slowing to 0.6% between 2001 and 2021. However, the overall sprawl from 1991 to 2021 amounted to 145.70%. The findings underscore the urgency of implementing sustainable urban planning and management strategies to mitigate the negative impacts of urbanization and enhance the region's sustainability and livability
