ABSTRACT: Effective planning relies on accurate and up-to-date
information on existing land use and land cover. The timely detection of trends
in land use and land cover change and a quantification of such trends are of
specific interest to planners and decision makers. The aim of this research is to use remote sensing and GIS to monitor
landuse and land cover change in Egbeda Local Government Area, Oyo State with a
view to determining how useful such information can be to planners and decision
makers for effective urban management. The research was conducted using remote
sensing and Geographical information System at determining the trend and extent
of land use and land cover change and its driving force in Egbeda Local
Government Area, Oyo State. The methods used include: digitization, digital
image processing and spatial analysis using an inverse distance weighted (IDW)
technique, Maximum likelihood supervised classification and post classification
change detection techniques were applied to Landsat imageries acquired in 1984,
2006 and 2018. Imageries were classified into built-up area, vegetation, bare
surface, cultivation and water body. The results of the analysis obtained
showed drastic change in built-up area which rose to 32.8% from 25.4% between
1984 and 2018 periods. To reduce the effect of land use expansion in the study
areas, policy measures were recommended which include proper inventory of land
use and land cover, regular monitoring of urban areas spread of development and
regional development programs. These will enable the government, stakeholders,
policy makers and planners to make informed decisions provided by these
technologies to attain and sustain future urban development.
