Abstract
This paper aims at detecting and analyzing urban-rural land use and land cover change of Ilorin and its environs of Kwara state in Nigeria, using Remote sensing (RS) and Geographical Information System (GIS). In this study three Landsat imageries were acquired. The analysis covers 1986, 2000 and 2006 due to availability of Landsat imageries covering the study area adopting six distinct classifications of land use using supervised classification method. ArcGIS and ENVI software were used for data processing, while SPSS was used for the statically analysis. The marginal population and the impervious land use and land cover in the study area were calculated. The study reveals a 29.2% and 150% increase in built up land between 1986 – 2000 and 1986-2006 respectively. The rate of Land and vegetation consumption is worrisomely unsustainable, where over 155km2 of land and vegetation is encroached for various forms of developments within six year period (2000 – 2006). It’s therefore recommended as a matter of urgency a smart growth, Brownfield redevelopment strategy and a well-equipped development control mechanism in the Local Planning Authorities, out of other measures for land resources sustainability
