This study analyses the land use changes on agricultural lands in Oyo metropolis from 2000 to 2024 using geospatial techniques. Landsat satellite imagery was employed to assess changes in the identified five land use classes: built-up areas, farmland, open spaces, shrubs, and water bodies. The analysis revealed a significant decline in farmland, which accounted for 46.25% of the total land lost, while open spaces expanded by 53.37%, and built-up areas increased by 2.18% reflecting urbanization and land conversion pressures. The study also observed an alarming annual farmland loss rate of -4,460.46 ha / year, highlighting the adverse effects of urban expansion on agriculture. Additionally, vegetation cover (shrubs) declined by 9.29%, indicating potential environmental degradation, while water bodies showed negligible change (-0.01%), suggesting relative stability. these findings underscores the urgent need for sustainable land use policies to mitigate the loss of agricultural land and ensure food security in the area. The study recommends implementing zoning regulations, promoting sustainable farming practices, and strengthening Geographic Information System-based monitoring to track landuse dynamics. By adopting these measures, policy makers and stakeholders can better manage land resources and minimize the negative impacts of rapid urbanization on agriculture.
