- Abstract
Towards the drive for environmental sustainability and sustainable urban development, geospatial technology has been deployed to study land use/land cover (LULC) dynamics in Abeokuta and environs, Southwestern Nigeria. The natural, human and social-economic interventions on the landscape have assumed prominent dimensions. The aim of this study was to evaluate the trend, rate and magnitude of changes, within the framework for effective planning and sustainable growth. Three sets of land satellite imageries (30 m × 30 m resolution) of 2001, 2008 and 2015 were harnessed for the study. Contrast enhancement and considerations were made to minimize radiometric effect due to seasonal changes. A supervised classification was conducted using maximum likelihood algorithm while a Markovian transition estimator (MTE) was applied for the prediction of future land cover change. Urban areas increased sharply from 938.82 km2 (19.18%) in 2001 to 1423.58 km2 (29.08%) in 2015. The area under shrubs cover increased at a rate of 1.08 km2 (0.07%) per annum. Forested wetland and farmland declined from 871.67 km2 (17.80%) to 795.43 km2 (16.25%) and 1445.77 km2 (29.53%) to 1022.13 km2 (20.88%) in 2001 and 2015, respectively. The net decrease indicated the anthropogenic interference into surrounding natural landscape. Effective policy planning and sustainable growth require proactive and holistic monitoring of LULC dynamics. This will facilitate informed decisions on land resources, environmental sustainability and sustainable urban development in the region.
