Background and Objective: Human actions threaten all of the Earth’s ecosystems. The resultant effect of human exploitation has left the ecosystem further degraded and the innate human dependence on its services less sustainable. Consequently, this study estimated the total land area for the ecosystems within the study area and assessed the level of degradation over a 17 years study period using historic satellite imageries. Materials and Methods: The historic satellite imageries were subjected to both land use/land cover classification and ecological classification using ArcGIS 10.3. The ecosystems found in the study area include the evergreen rainforest, littoral rainforest, swamp forest, woodland and grassland, Atlantic Ocean mangrove and water. Results: The result showed the total land area coverage of ecosystem (146,682 ha) and significant depletion of ecosystem in the study area, with the swamp forest being the largest ecosystem depleted in terms of land area (5,064 ha) at the study’s concluding year. In total, 2,822, 3,655, 6,805 and 7,521 ha of ecosystem land area coverage was depleted in year 2000, 2006, 2011 and 2016 respectively. Conclusion: With this, integrating ecosystem management into urban planning approaches would go a long way in improving the quality of people’s life and promoting the sustain ability of ecosystem services.
