dc.description.abstractWorldwide urbanization has significantly modified the radiative, thermal, moisture and aerodynamic characteristics of the landscape, which affect the surface energy balance within the atmosphere. Such modification can lead to urban heat island phenomenon where urban surface and air temperatures are higher than their corresponding rural areas. Remote sensing and GIS were used to evaluate the effect of urban growth on temporal variation of surface temperature in Katsina Metropolis. Landsat Thematic Mapper (TM), Enhanced Thematic Mapper Plus (ETM+) and Landsat-8 Operational Land imager (OLI) images of 1986, 1999 and 2014 respectively were utilized. Land use land cover maps were generated using supervised classification. The four (4) land use land cover classes identified in the study area are farmland, vegetation, bareland and built up. Thermal band data was used to compute surface temperature maps for the three years and the relationship between land use land cover and surface temperature was analyzed. Findings from this study revealed that there is a general decline in natural surfaces and increase in developed surfaces from 1986 to 2014. The resulting GIS analysis showed that built up is increasing at an annual average rate of 5.1 % while the Surface Temperature has gone up by more than 17oC during the study period. If the built up continues to increase at the rate mentioned above and vegetation decline at an annual rate of 0.8%, Surface Temperature will be on the high side and this may bring about urban heat island. Therefore, planting of trees and vegetation in and around the metropolis should be encouraged to minimize the increase in surface temperatures of the land use/cover types which may also affects the mean surface temperature of Katsina metropolis.en_US
