Abstract


An understanding that little or no profit can be derived from a dead environment calls our attention to embrace sustainable development in the urban centers of Nigeria. This study assesses the impact of coastal urban development in Eti-Osa LGA (Lagos) on the environment, thus is the need to evaluate spatio-temporal change uing of remote sensing/GIS techniques. Landsat imageries of 1984, 1999, 2006 and 2014 were used for the land cover change detection and the thermal band (band 6) of Landsat imageries of 1999, 2006 and 2014 were used for the surface temperature analysis. Maximum likelihood supervised classification and Post-classification comparison techniques were adopted to justify the extent of urbanization. The impact of urban development on the environment was examined through urban thermal variation analysis using the Urban Boundary layer approach. Results from this study has illustrated the advent of gross urban expansion that; 12.43% of built-up area, 20.51% reduction in riparian forest, 0.16% reduction in the water body coverage and an attendant variation in both water/land surface temperature, are impacts of diverse human development on the environment. This is an attempt not only to save our dying environment but also to keep man in a healthy and habitable environment.
