Urbanization and Deforestation Impacts on Geomorphology and Land Use Patterns in Enugu State, Southeastern Nigeria

Odoh, Benard Ifeanyi Nwokeabia, Charity Nkiru and Callista Nwanneka Igwebudu


Abstract


The study examines Land Use and Land Cover (LULC) changes and their implications in Enugu North, Enugu South, Nkanu East, and Nkanu West LGAs, Enugu State, southeastern Nigeria, between 2017 and 2023. The aim is to assess the impact of these changes on the environment and to understand the influence of slope on land use suitability. The methodology involved analyzing satellite imagery and topographical data to classify LULC types and calculate slope ranges. The results show a significant reduction in tree cover from 565.99 km² to 432.48 km² and an increase in built-up areas from 204.51 km² to 328.73 km². Rangeland expanded from 456.40 km² to 504.03 km², while agricultural lands decreased from 97.70 km² to 60.77 km². Water bodies and flooded vegetation also declined slightly. The discussion highlights the environmental implications of these changes, such as deforestation, urbanization, and shifts in agricultural and grazing activities. The predominance of gentle slopes (0° to 4.17°) suggests suitability for various land uses, while steeper slopes (above 4.17°) present challenges for agriculture and construction. The study emphasizes the need for sustainable land management practices to balance urban growth with environmental conservation. The significant reduction in tree cover and increase in built-up areas underscore the impact of rapid urbanization and land conversion in the region. The findings highlight the importance of integrating slope analysis into land use planning to mitigate erosion risks and promote sustainable development. This study provides valuable insights for policymakers and planners in managing land resources effectively. This research uniquely combines LULC change analysis with slope dynamics to provide a comprehensive understanding of land use patterns and their environmental implications in a rapidly urbanizing region.
