The rapid urbanization and expansion of cities have become a global concern, with a profound impact on the environment, infrastructure, and the quality of life for residents. This study focuses on ETI-OSA Local Government Area, an area characterized by significant population growth and urbanization which makes it important to monitor and understand the dynamics of urban sprawl so as to ensure the well-being of the study area’s residents and the responsible use of resources.
To assess urban sprawl in ETI-OSA, this study employed a multidisciplinary approach that integrates Remote Sensing and Geographic Information Systems (GIS). Landsat Satellite imageries were acquired for the periods under study, that is, Landsat 4-5 for 1994, Landsat 7 and 9 for 2004 and 2014, and Landsat 9 for 2024. The techniques employed in this research are mosaicking, image clipping and supervised classification.

The results of this study shed light on the extent and patterns of urban sprawl in ETI-OSA Local Government Area. The analysis indicates a significant increase in urbanized land areas over the study period of 30 years which quantifies the extent of urban sprawl and its spatial distribution. This trend is a clear manifestation of urban expansion and population growth in the region. The implications of these findings are profound, as they provide valuable insights for land-use planning, resource allocation, and infrastructure development.
