Abstract
Urban expansion affects land cover at local, regional and global scales. Like other towns in Nigeria, Shika is growing at a very fast rate. The consequence of such urban growth if unplanned is the adverse effects on the environment. The aim of this research was to Assess the Effect of Urban Encroachment on Guga Forest Reserve in, Shika, Giwa Local Government Area of Kaduna State, Nigeria using Remote Sensing and Geographic Information (GIS) techniques. Landsat MSS imagery of 1986, Landsat TM imagery of 1990, Landsat ETM+ data of 1999 and Landsat 8 OLI image (2014) were used. The datasets were processed and classified into land use/land cover classes using the supervised classification technique in Erdas imagine 9.2 environment and ArGIS 10.1. The built-up area and forest land was extracted separately and the rates of growth between the periods (1986-2014) were ascertained. The built-up areas for the four time periods were overlaid in order to derive the urban growth map. The result revealed that built-up increased from 15.9 hectares in 1986 to 54.7 hectares in 2014 while forest land reduced from -7.8 hectares to -194.0 hectares within this same period. The built-up in the study area was increasing at the 0.9% yearly while the forest land was declined at the rate of -1.1% per annum within the period (1986-2014) studied The study recommend that Remote Sensing and Geographic Information System (GIS) technique which have proved to be efficient in the monitoring of forest/vegetation cover, This would help to control encroachment and reduce indiscriminate exploitation of the forest cover.
