GEOSPATIAL ANALYSIS OF THE IMPACTS OF FLOOD VULNERABILITY ON LAND USE LAND COVER CHANGES IN BAUCHI METROPOLIS

Abstract

This study investigates the geospatial impacts of flood vulnerability on land use and land cover (LULC) changes within Bauchi Metropolis. Using a combination of satellite imagery, Geographic Information Systems (GIS), and statistical analyses, the research identifies flood-prone areas and their correlation with various land cover types. The study reclassifies LULC into flood vulnerability categories, highlighting areas with very high, high, moderate, low, and none vulnerability levels.Results indicate that 5.87% of the area falls into the very high vulnerability class, predominantly comprising urban and built-up zones. Conversely, 52.11% of the area is moderately vulnerable, representing mixed land uses with moderate flood susceptibility. The analysis further reveals the critical role of farmlands and woodlands in mitigating flood risks. High-risk zones, including Baraya, Gwallagan Mayaki, and Zango, require immediate intervention to prevent severe flood impacts. Moderate and low-risk areas demand proactive urban planning and sustainable land management to prevent escalation in vulnerability.The study employs advanced geospatial techniques to classify flood risks and presents actionable insights for policymakers, urban planners, and disaster management agencies. By identifying flood-prone areas and their specific LULC types, the research provides a foundation for targeted flood mitigation strategies, such as enhanced drainage systems, improved land management practices, and the preservation of natural vegetation. This comprehensive geospatial analysis underscores the necessity of integrating land use planning with flood risk management to enhance the resilience of Bauchi Metropolis to future flooding events.
