Abstract: Abstract Analysis of land use/land cover change (LULCC) and their impacts on the natural environment is essential in policy decision for an effective solution to the sustainability of the earth system. This study employed supervised image classification (maximum likelihood) algorithm to map changes in land use/land cover for a period of 4.5 decades (1972–2017) in Ekiti State. Vegetation and temperature dynamics were examined for the selected years using normalized difference vegetation index (NDVI) and land surface temperature (LST), respectively. NDVI and LST were statistically compared to understand the potential impacts anthropogenic activities on the environment. Resultant LULC maps indicated a decrease in forests and woodlands at a change rate of 51.25 and 0.72% over the last 4.5 decades in Ekiti State, while built-up areas, croplands, rocks/bare soils and water bodies have increased about 267.58, 197.30, 714.11 and 4421.43%, respectively. Agricultural lands (now occupying 47.13%) are the major contributor to the net change in forests (decreasing). LST showed a negative correlation with NDVI (r = −0.672). Mean LST are in the order 22.7 °C (1984)
