Disaster Risk Reduction in Flood-Prone Urban Areas

Abstract

Urban flood disasters represent one of the most pressing challenges facing contemporary cities, exacerbated by climate change and rapid urbanization. This paper examines disaster risk reduction strategies in flood-prone urban areas through a comprehensive analysis of current research and case studies. The study explores the intersection of climate-induced extreme precipitation events, unplanned urban expansion into high-risk zones, and the resulting vulnerabilities that threaten lives, infrastructure, and economic stability. Drawing on the Sendai Framework for Disaster Risk Reduction (United Nations Office for Disaster Risk Reduction, 2015) and contemporary scholarship (Wang et al., 2022), this paper analyzes both structural and non-structural mitigation approaches, including green infrastructure, nature-based solutions, early warning systems, and community resilience building. The research reveals that effective disaster risk reduction requires integrated approaches combining physical interventions, governance reforms, and community engagement. Findings indicate that while grey infrastructure remains important, nature-based solutions (Ghosh et al., 2024; Takin et al., 2023) and flood-sensitive urban planning offer sustainable pathways for reducing flood risk. The paper concludes by emphasizing the urgent need for risk-informed development policies and adaptive strategies that balance urban growth with flood resilience.
