This research focused on Land use/Land Cover (LU/LC) and Vegetation (greenbelt) conversion. Worldwide scholars opined that, urban areas grow at the expense of forests (Hutyra et al. 2011; Pretzsch, 2015) Sokoto State Nigeria, was not an exception and the LU/LC conversion has taken place as a result of different anthropogenic influences. How much of the conversion is yet to be ascertain, the research will therefore, detect, map and evaluate the Spatio-temporal LU/LC and vegetation conversion. Normalized Difference Vegetation Index (NDVI) was computed for the study area after applying image pre-processing and processing, standard algorithms to near-anniversary dry season, Landsat data of 1986, 1994, 2005 and 2015. Z-scores were calculated for the NDVI images, while each was classified using 1 standard deviation to the mean (? ? ?) algorithm. Computation of NDVI was carried out to determine the vegetation change. The finding indicates a total land cover of 10, 673 hectares in 1986; vegetation (32%), open space (55%) and built-up (13%) However, in 2015; vegetation (11%) open space (58%) and built-up (31%). Thus, 11% vegetation remains, indicating 2/3 (21%) of the vegetation lost to other land uses in three decades (1986-2015) Keywords: Urban Planning, Land use/Land cover, Vegetation, Greenbelt Conversion,
