ABSTRACT: Urban development and economic dependence on land and its abundant resources have been the major driving forces shaping various landscapes. It is well known that large development influences the climate. Hence, understanding the Spatio-temporal distribution of Land Surface Temperature will help in mitigating its effects. This paper investigates different types of land use land cover in Ikorodu and assesses its impact on land surface temperature between 1986 and 2016, using Remote Sensing and Geographic Information System techniques. Landsat TM, ETM+, and OLI images were obtained from USGS for this study. Four classes considered for the study were Settlement, Water bodies, dense vegetation, and Wetlands. Settlement covered areas of approximately 7.03%, 22.69%, and 64.11% in 1986, 2002, and 2016 with the corresponding mean land surface temperature of 24.82°C, 29.47°C, and 32.63°C respectively. Dense vegetation happens to be the most noticeable change. It covered 55.69%, 51.80%, and 19.41% in 1986, 2002, and 2016 with temperature values of 20.04°C, 22.76°C, and 26.31°C. Also, the wetland has reduced from 33.31% to 14.27% with an increase of 3.04°C in temperature. A Strong inverse correlation exists between LST and NDVI, which indicates that green land can be used to reduce the effect of the increase in land surface temperature.
