IMPACT OF SOIL EROSION ON BUILDING COSTRUCTION IN LAMURDE LOCAL GOVERNMENT AREA OF ADAMAWA STATE, NIGERIA

This research, conducted in Lamurde Local Government Area, Adamawa State, Nigeria, addresses the critical threat of soil erosion to building infrastructure and socio-economic stability. It investigates the multifaceted impacts of soil erosion, moving beyond a general assessment to provide a detailed, localized analysis. Employing a comprehensive mixed-methods approach, the study combines rigorous on-site structural assessments of erosion-affected buildings with in-depth community surveys to capture lived experiences and economic consequences. Geotechnical investigations characterize soil properties and erosion rates unique to Lamurde's environment, considering factors such as rainfall intensity, land use practices, and topographical features. The findings reveal that: a. Unchecked soil erosion leads to significant foundation instability. b. Widespread wall cracking occurs due to soil erosion. c. There is an increased vulnerability to catastrophic structural failure affecting residential, commercial, and public buildings. d. Soil erosion results in a substantial economic burden on homeowners and the local government. e. Key drivers of erosion include unsustainable agricultural practices, deforestation, and inadequate drainage systems. To address these challenges, the research advocates for:1. Urgent adoption of site-specific, integrated erosion control measures tailored to the unique environmental and socio-economic context of Lamurde. 2. Implementation of terracing and reforestation initiatives using native species.​ 3. Construction of improved drainage infrastructure. 4. Integration of erosion-resistant materials and construction techniques in future building projects. 5. Emphasis on community engagement and capacity building to ensure the long-term sustainability of interventions. Ultimately, this research provides a critical evidence base for policymakers, engineers, and community stakeholders to develop and implement effective strategies to mitigate the impacts of soil erosion, safeguard the built environment, and foster a resilient future for Lamurde.
