    Abstract: ArcGis 10.1 Software and Landsat 7 imageries of 1985 and 2017 were used for this study. The result
of the research showed a rapid growth in built-up land occupying 182.2 km<sup>2</sup> (70.0%) and cultivation occupying
7.4 km<sup>2</sup> (2.9%) in 2017 while 1985 witnessed a reduction in this classes having 83.4 km<sup>2</sup> (32.0%) and 3.7 km<sup>2</sup>
(1.4%), respectively. In 1985, vegetation occupied 169.9 km<sup>2</sup> (65.3%) and experienced a reduction in 2017 to
67.4 km<sup>2</sup> (25.9%) while water body remained 3.3 km<sup>2</sup> (1.3%) with little or no notable changes between the
referenced years. It was also observed that the changes that occurred in the sampling points at the referenced
years replicated itself in other parts of the study area, hence, the recommendation to raise awareness among
relevant stakeholders about the importance of protecting vegetative land cover as well as the adverse effects
and consequences associated with deforestation, overgrazing and improper agriculture activities on vegetation.
