Abstract
As cities rapidly develop to accommodate the growing urban population, a transformation in city landscape becomes inevitable leading to changes in land use and land cover, this has environmental and ecological consequences one of which is the changes observed in the micro climate of major cities. This study employed remote sensing and GIS in evaluating the influence of land use/land cover (LULC) change in the Federal Capital City (FCC) Abuja on surface temperature. A nineteen year study period was chosen with specific objectives to examine land use land cover changes within the set period, assess the growth of urban FCC and examine the effect of this growth on surface temperature and subsequently, urban heat island (UHI) development. Three Landsat TM and ETM+ images of the study area (1987, 2001 and 2006), all acquired in the dry season (September to December) were used to complete the study; Land use/ land cover analysis was carried out using IDRISI 17.0 and Land surface temperature of the various land uses for all three years was extracted from thermal band (6). LULC was found to increase (18.57%) in areal extent for built up between 1987 and 2001 while by 2006, a 2.31% decrease for built up is recorded, showing changes in urban growth and consequently, on surface temperature. correlation analysis was carried out and the degree to which UHI was present in the city established
