Abstract :
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.
