This study examines the use of GIS and Remote Sensing in Mapping Land Use/Land Cover changes in the University of Port Harcourt host communities, mainly Choba, Aluu and Alakahia, between 2005-2010 and 2010-2015, to recognise the changes that have taken place in these peri-urban areas within the period of study. The study aim is to detect and map the land use/land cover of the area over a period of 10 years (2005-2015). Three data set of Landsat Satellite images were layer-stacked, after which supervised classification in EARDAS imagine software was carried out and mapping in Arc GIS software were carried out. Five land use and land cover categories were distinguished: built-up areas, cultivation, vegetation, and water body. The results of the study show rapid growth in built-up land between 2010 and 2015, whereas the periods between 2005 and 2010 witnessed an increase in this class also. The rapid increase in built-up areas revealed by the study is due to the rapid urbanization and industrialization in the peri-urban area. It was further observed that the increasing population of students in the area brings about much more demand on housing, which resulted in a great detrimental effect on the land cover of the area in recent years. The study, therefore, recommends, amongst others, the regulation of land use in the peri-urban area, encouragement of afforestation by government and other critical stakeholders, and provision of a mitigating control measure to realistically address the contemporary issues of rapid urbanization in the peri-urban areas.
