Global land use has significantly changed during the past decades due to the urban expansion. Historically, the driving force for land and use changes is population growth and urban expansion. Rwanda as the most densely populated country in Africa with population was estimated to be about 11.37 million, of which 28.81% resided in urban areas and by2030, this population is expected to reach about 17 million, with 41.55% living in cities. This study aimed to assess the dynamism of urban expansion, determining the land use and land cover change (LULCC), and showing the effect of urban expansion and LULCC of Bugesera over a period of 2002 to 2022. For determining the dynamism of urban expansion, statistical data collected from National Institute of Stastics of Rwanda(NISR) and district reports have been used and analyzed. The Land use and land cover change has been determined by use of secondary data obtained from Landsat images. By use of application of GIS (Geographical Information system) and remote sensing specifically with software ArcGIS Pro 3.0, the Landsat Images of different times were classified using supervised classification. It has been observed that over this entire period of 20years, the urban area has expanded up to 5766.751% which is also the increase of built up areas; with population increase of 179.831%. The forest, water bodies and wetland have experienced an increase of 241.451%,156.470% and 61.366 % respectively. These increases are justified by the policies that the government has established regarding to restoration of the nature. The vegetation and agriculture land experienced the decrease of 38.644% and 37.761% respectively. The local people should comply with the national land master plan during their activities as the human activities are among the contributors of environment degradation, they should avoid any activity which harm the natural environment. Researchers should also interest the players in environmental protection to be inspired by use of GIS and remote sending tools during monitoring of urban expansion and LULCC. Local leaders should strengthen the implementation of planning policies by respecting Environmental rules and regulation related to the zonings. The Government should increase awareness to the population in the application of circular economy practices which result the resource efficient and reduction of wastes.
