ABSTRACT: Information on the dynamics of savannah is important to a country's plan
to overcome the problems of uncontrolled development and environmental hazards.
Taking the reserve partielle de Dosso, Niger as the case study area, this paper
analyzed the long-term land use land cover change from 2002 to 2022. Satellite
images were processed by using Google Earth Engine (GEE). Therefore, four major
land cover classes were identified based on spectral characteristics of Land
sat, namely, built-up, vegetation, cropland, bare land and water. The result
revealed that barren and built-up areas increased at the expense of vegetation
and water. From the four major land use land cover the large area is covered by
vegetation which comprises about 192963.5 hectares followed by cropland and
water consisting of 32506.43 and 1596.4 hectares respectively. The built-up
area gained substantial area (most) during the study period. The reduction in
some of the land cover/uses underlines the dangerous trend of the pressure
poised by population growth and the changing functionality. Land cover change
is influenced by a variety of societal factors operating on several spatial and
temporal levels. The area estimates and spatial distributions of the LULC
classes produced from the current study will assist local authorities,
managers, and other stakeholders in decision-making and planning regarding
forest land cover and uses.
