The Impact of Economic and Climate Change Factors on Flooding in Borno State, Nigeria: Causes, Consequences, and Policy Responses

Abstract

Flooding has become one of the most pressing environmental challenges in Nigeria, with Borno State increasingly affected by recurrent flood disasters. This study investigates the impact of economic and climate factors on flooding in Borno, focusing on its causes, consequences, and policy responses. Using a mixed-methods approach, the research combined quantitative household surveys, qualitative interviews, focus group discussions, and secondary data from meteorological and institutional sources. Findings reveal that climatic variability particularly erratic rainfall, rising temperatures, and river overflows remains a central trigger of floods. However, economic and human factors such as rapid urbanization, poor drainage systems, deforestation, poverty, and population displacement significantly amplify vulnerability. The consequences are multidimensional, encompassing agricultural losses, infrastructure damage, displacement, health crises, and environmental degradation. Policy responses by government and humanitarian agencies were found to be largely reactive, focused on relief distribution rather than long-term adaptation. Local communities employ coping mechanisms such as sandbag barriers and traditional flood prediction, though these remain insufficient without institutional support. The study concludes that flooding in Borno represents a compound vulnerability shaped by conflict, climate change, and economic fragility. It recommends strengthening early warning systems, improving urban planning, promoting climate-resilient agriculture, and mainstreaming conflict sensitivity in flood management. By shifting from short-term relief to long-term resilience, stakeholders can mitigate the impacts of flooding and promote sustainable development in Nigeria’s northeast.
