Abstract:

The Niger delta region of Nigeria being the sole oil producing region of the nation has witness increase anthropogenic activities over the last three decades. These activities have had serious impact on the natural Land use/land cover and it is believed that this has in turn affected the Land Surface Temperature (LST) dynamics. Hence, this research seeks to investigate the relationship between Land use/Land cover(LULC) change and Land Surface Temperature (LST). Landsat 5(TM), 7 (ETM+) and 8 (OLI) images of 1986, 2002 and 2016 were used for the land use/land cover classification and the thermal bands of the corresponding Landsat was used to obtain the Land surface temperature. The three dataset of images were classified into seven LULC classes using supervised maximum likelihood algorithm and the LST maps for the corresponding years (1986, 2002 & 2016) of Landsat were also generated. ArcGIS was then used to evaluate the relationship between Land use/land cover and land surface temperature (LST). The result indicated that LST changes followed the pattern of LULC changes overtime and the Heat Intensity appears to be at the peak in the high density settlement areas and low at the vegetated areas. The analysis revealed an increase of LST by 1.78 0C during the 30years period considered at the rate of 0.0590C/year in high density built up due to increase in settlement growth. The study concluded that a change in Land Use Land cover has an impact on the land surface temperature in the Niger delta region of Nigeria.
