Abstract


Flooding remains one of the most recurrent natural hazards, posing serious threats to agricultural land, food production systems, and rural livelihoods, particularly in rapidly urbanizing regions of developing countries. Understanding land use and land cover dynamics is therefore essential for assessing flood vulnerability and supporting sustainable agricultural land management. This study examines the impact of land use change on flood vulnerability of agricultural land and livelihoods in Suleja Local Government Area, Niger State, Nigeria. Multi-temporal satellite imagery was analyzed using Geographic Information Systems and remote sensing techniques to identify major land use categories and their changes over time. Supervised classification was applied to assess spatial patterns of land transformation. The findings indicate a significant expansion of built-up areas accompanied by a decline in agricultural and natural land covers, which has increased surface runoff and flood exposure on agricultural landscapes. These changes have heightened the vulnerability of livelihood systems dependent on land-based activities. The study underscores the importance of land use zoning and flood-sensitive agricultural planning to enhance resilience and promote sustainable food production in flood-prone environments. This study supports Sustainable Development Goals (SDGs).
