This in turn affects the natural resource base, hence a threat to the entire ecosystem. The study assesses the spatio-temporal changes of the vegetation cover in Bauchi. Remote Sensing, GIS techniques and questionnaire administration were employed to collect the data needed to address the research objectives. Multi-temporal satellite data (Land Sat Multi Spectral Scanner 1976 and Operational Land Imager 2015) were used for land cover-land cover (LULC) classification using Maximum Likelihood Classifier (MLC) tool resulting in land cover map of 1976 and 2015. They were further analysed for changes using the Post- Classification Comparison Technique. The SPOT-NDVI data of 1998 and 2014 with 8km resolution were used to generate vegetation density map using NDVI differencing method resulting in four density classes: low (0.1-0.2), medium (0.2-0.3), high(0.3-0.4) and very high (>0.4). A regression statistics was used to test for relationship between NDVI, rainfall and temperature. The data on the driving factors of vegetation changes were obtained through semi-structured questionnaire. The Findings revealed that the settled/cultivated land increased by 3918.4 km2 (35.8%) with an annual rate of changes of 14.32% followed by Shrubbed Woodland Hills by 1550.4 km2 (14.2%) with annual rate of changes of 5.60%. While, the other vegetation cover types decreased. The results also indicated that the area coverage very high NDVI density class had decreased by - 2991 km2 (50%) with annual rate of change of -8, NDVI high density class had increases by +1615 km2 (27%) with annual rate of change +4.3, NDVI medium density class had increased by 1099 km2 (18.4%) with annual rate of change of +2.9 and NDVI low density class had increased by +277 km2 (4.6%) with annual rate of change + 0.74. The regression coefficients showed a strong relationship between NDVI, rainfall andResearch Theses
