Urban settlements in developing countries face numerous severe problems due to rapid and often unplanned urbanization. Key problems include:
- Overcrowding and Housing Shortage: A massive influx of migrants leads to high population densities and an acute shortage of affordable housing, forcing many to live in overcrowded conditions.
- Growth of Slums and Squatter Settlements: Lack of affordable housing results in the proliferation of informal settlements (slums) characterized by poor living conditions, lack of basic amenities like clean water, sanitation, and electricity.
- Strain on Infrastructure and Public Services: Existing infrastructure such as water supply, sewage systems, electricity grids, and public transport is often overwhelmed, leading to frequent breakdowns and inadequate service delivery.
- Unemployment and Underemployment: The number of job seekers often exceeds the number of available jobs, leading to high rates of unemployment and a large informal sector with low wages and no job security.
- Environmental Pollution: High concentration of industries, increased vehicular traffic, and improper waste disposal lead to severe air, water, and noise pollution, posing significant health risks.
- Traffic Congestion: A rise in the number of vehicles without a corresponding expansion of road networks leads to chronic traffic jams, increasing commute times and pollution.
- Social Problems: Overcrowding and poverty can contribute to higher crime rates and social tension.
