Population development, speedy growth of events and natural processes set changes landuse/landcover (LULC). The effects of these transformations on natural resources and environment all around the world attract researchers globally. The LULC changes impacts on buildup Area. Open space, bare surface, Agricultural Land, water, Vegetation, Shrubs, Plantation In this investigation, Remote Sensing (RS) and Geographical Information System (GIS) technology were utilized rather than traditional methods. A Supervised classification (Maximum likelihood) alogorithm was applied on three Landsat TM images of 1991, 2002, and 2017 of Greater Karu Urban Area of Nasarawa State Nigeria. Change Analysis technique in Idrisi in Terrset was adopted to analyze the changes that have taking place over the years (1991, 2002, and 2017) According to the IPCC, Africa is one of the most vulnerable continents to climate change so climate drivers are likely to exacerbate this situation. In spite of this knowledge, Africa is the least covered by climate change research; these studies incorporated the effect of urbanization and its impact on the ecosystem looking at how urbanization impact on the global climate system
