Anthropogenic drivers such as the urbanization and economic dependence have being a major force shaping various landscapes. Kaduna town is no exception of such landscapes. This study uses remote sensing and GIS techniques with survey to identify the various land uses, their various transformations over the a period of 11 years (1990-2000)and to measure the rate of urban expansion and loss of vegetation cover in the study area. The study revealed that built-up area is expanding at about 167.86 hectares annually vegetation covers declining at a faster rate of 297.5 hectares annually. It also revealed that bare land a component …

Since Lokoja became an administrative headquarters of Kogi State in 1991, it has been experiencing rapid expansion, urbanization and significant changes in its physical landscape – land use and land cover changes. This study uses remote sensing and GIS techniques combined with field checks and survey to map land use and land cover changes and to measure the rate of urban expansion and loss of vegetation in Lokoja between 1987 and 2005. There was a considerable change in land use types over the said period of the study. The built-up area, vacant land, cultivated land and other land use type …
