The Role of Unplanned Urbanization in Water Scarcity and Drainage Problems: A Review in Bangladesh Perspective

Rapid urbanization and population growth in Bangladesh, are increasing vulnerability to hazards like floods, earthquakes, fires, and water logging. This has led to social, physical, economic, and environmental consequences, such as disruption of life, water scarcity, infrastructure damage, and extinction of wildlife. This study examines the impact of unplanned urbanization on water scarcity in Bangladesh's rapidly growing cities, assesses its effect on drainage systems, and proposes strategies for mitigation. This study conducted a comprehensive analysis of unplanned urbanization in Bangladesh, examining its effects on population, water sources, and drainage systems. The research assessed the interconnections between urbanization, water scarcity, and flooding by drawing on secondary data from various sources. Additionally, it proposed strategies to mitigate these challenges and promote sustainable urban development. Finally, some possible and practical solutions for managing urbanization have been suggested to tackle water scarcity and drainage problems in Bangladesh.
