Abstract

Quarrying activity is one of the major causes of land use /land cover changes in Nigeria with effects on the natural ecosystems. This study employed Landsat TM:1984, 2000 and OLI/TIRS2014 to assess land use and land cover changes due to quarrying activities in Odeda, Ogun State, Nigeria. A supervised method classification was employed using the Maximum likelihood algorithm. Area covered by quarry sites decreased from 52.26 hectares in 1984 to 114.206 hectares by 2000 and then 240.759 hectares in 2014. On the other hand, light forest, which had largest cover of 637.282 hectares in 1984 reduced to 614.678 hectares in 2000 and drastically to 326.517 hectares by 2014. Land degradation, dust, noise and vibration originating from quarries are major environmental impacts of quarry operations in the area. Enforcement of regulations and laws through effective monitoring by the required institutions will create a balanced and sustainable environment.
