Abstract
This study therefore examined the integration of Remote Sensing and Geographic Information System (RS/GIS) for analyzing land use and land cover dynamics in BirninKebbi, the Kebbi State capital for the period 1986 to 2009. Land sat (TM) images of 1986, 1999 and Nigerian Sat-1image of 2009 were used. The study employed supervised digital image classification method using Erdas Imagine 9.2 and Arc GIS 9.3 software and classified the land use into built up area, riparian vegetation, bare lands, grassland, Agricultural land and water bodies. The images were made to pass through the processes of georeferencing, image enhancement, image resampling and classification. The results obtained shows that the built-up area has been increasing rapidly for the periods (1986-1999) by 547.3% .This is evident in the increased Land Consumption Rate (LCR) from 0.022 to 0.089 in 1986 and 1999 respectively and Land Absorption Coefficient (LAC) by 0.201 within the same period. While between 1999 to 2009 witnessed a drop in (LCR ) at which the physical expansion of the was going on from 0.0089 in 1999 to 0.031 in 2009. This is evident in the drop observed Land Absorption Coefficient (LAC).The results also showed increase in the grass land while Agricultural land decreases, the water bodies were stable between 1986 and 2009. These results could help city planners and policy makers to attain and sustain future urban development. It is therefore recommended that encouragement should be given to people to build towards the outskirts, like Zauro, Ambursa etc through the provision of incentives and forces of attraction that is available at the city center in these areas to avoid the problem of overcrowdings.
