Abstract
The aim of this research is to examine the geo-spatial analysis of informal settlements on landuse/ cover change areas of Osogbo with a view to improve strategies to protect land use/cover change for sustainable development. The research was conducted using remote sensing, Geographical information System and questionnaire to collect the required data for the purpose of fulfilling the objectives of this study. The effect of spatial expansion of informal settlements on land use/ cover were analysed in this research for a period of forty-four years. The study made use of satellite imageries of Landsat (MSS) images of 1972, 1986 and 1991 (TM), Landsat Enhanced Thematic Mappings (ETM+) of 2002 and 2016. The study employed supervised digital image classification method using ILWIS 3.2 and ArcGIS 10.3 software to classify the landuse/ landcover into built-up area, vegetation, gallery forests, cultivation and water bodies. Digitized maps were carefully overlaid and calculated to get the different trend of changes in the Informal settlement and its impact on land use/ cover cultivation. The results of the analysis reveal that the built-up area (informal settlement) has been growing rapidly for the periods (1972-2016). Findings also show increase in cultivation while vegetation decreases, the water bodies were stable between 1986, 1991 and 2002. Based on the GIS analysis, future prediction/ trend of the informal settlements and its subsequent impact on land use/ cover were modeled between 2002 and 2023. Findings show that, housing provision, business purpose and industrial are the major causes of land use change in the study areas. To reduce the effect of land use conversion in the study areas, policy measures were recommended which include regulating the growth and spread of development and regional development programs.
