Abstract: Land use transformations have substantially altered the natural environment in which humans live and in urban areas, the declining air quality poses a large threat to human health. To investigate the relationship between land use, land cover change and air pollutants, a non-segregated approach was used in combining remote sensing techniques with Geographical Information System. The land use and land cover in this study were categorized into the following; Water Bodies, Bare Land, Vegetations and Built-up area. The pollutants considered are; PM2.5, SO2, NO2 and CO. The annual average for 2021 was observed to be 47.46 μg/m3 which exceeded the threshold value of EPA 15μg/m3. Understanding the effect of pollutants on land use and land cover using Pearson correlation, it was observed that PM2.5 had a negative correlation of (-0.921) on water. Results also indicated that SO2 had a positive correlation (0.91) with vegetation, while CO indicated a positive correlation of (0.31) on bare land. In addition, NO2 had a negative correlation of (-0.62) on built-up area, and a positive correlation on Bare land. Analysis indicated an increase of (0.86%) in vegetation and (66%) in built-up area. While registering a simultaneous decrease of (39.9%) in water bodies and (15%) in bare land from 2001 to 2021. The findings from this observation constitute and suggest a valuable benefit of knowledge of regulations aimed at improving, safeguarding, and monitoring air quality. These outcomes may be used to inform land-use in making planning decisions in a comprehensive way and will be an empirical tool for LUCC rationalization and control strategies.
