Abstract:

This research evaluates the spatial and temporal dynamics of land use/land cover (LULC) of the Niger Delta Region of Nigeria from historical multispectral remote sensing datasets of Landsat 5(TM), 7 (ETM+) and 8 (OLI) images of 1986, 2002 and 2016. Image processing was implemented with ERDAS IMAGINE and ENVI software. ERDAS IMAGINE, IDRISI and ArcGIS software are used for evaluation of the spatial and temporal dynamics of Land use/Land cover of the study area. The three sets of Landsat images are classified into seven land use/land cover classes using supervised maximum likelihood algorithm in ERDAS IMAGINE and further LULC analysis was done in IDRISI and ArcGIS software. The computed Overall Classification Accuracy and KAPPA (K^) STATISTIC were 66.7% and 0.60; 70.1% and 064; 74.5% and 0.70 for 1986, 2002 and 2016 respectively. The spatial and temporal analyses indicate that from 1986 to 2016, all LULC classes are significantly altered from their initial state. The forested areas had the heaviest depletion of 29.09%. Mangrove and vegetation also had losses of 1.85% and 2.17% respectively. The high and low density built up areas had gains up to 20% through conversions of forested and arable vegetated cultivated lands to settlements.
