In News
- According to a 2024 study, over 158 million people live in slums located in floodplains in South Asia, with India having the maximum share.
- Around 40% of slum dwellers in India reside in urban and suburban areas.
Growth of Slums
- Slums are densely populated urban areas characterised by poor-quality housing, the lack of adequate living space, public services, and accommodating large numbers of informal residents with insecure tenure.
- According to UN-Habitat (2021), slum dwellers across the globe have increased from 980 million in 2010 to 1,059 million in 2020, accounting for 24.2% of the world’s urban population.
- India’s slum population in 2020 is estimated at 236 million suggesting that nearly half of its urban population lives in slums (UN-Habitat 2021).
Factors Driving Slums
- Rapid Urbanization: Massive rural-to-urban migration for livelihood and better opportunities leads to unplanned settlements.
- Lack of Affordable Housing: Insufficient low-cost housing forces poor migrants to settle in informal slums.
- Poverty and Unemployment: Economic insecurity prevents access to formal housing markets.
- Land Scarcity and High Land Prices: Urban land shortages and expensive prices restrict housing availability for the poor.
- Inadequate Urban Planning and Governance: Poor infrastructure, lack of formal tenure, and weak municipal services drive informal settlements.
- Social Exclusion: Marginalized groups face discrimination, limiting their access to decent housing.
- Environmental Factors: Slums often develop in hazard-prone areas like floodplains (e.g., Ganga delta) due to low-cost land availability.
Impacts and Concerns
- Health and Sanitation Risks: Overcrowding, poor sanitation, and lack of clean water cause public health issues.
- Vulnerability to Disasters: Slums are disproportionately affected by floods, heatwaves, and other climate-related disasters.
- Social Challenges: Slum dwellers face insecure tenure, social stigma, poor education, and limited access to services.
- Environmental Degradation: Waste accumulation and lack of green space degrade urban environments.
- Economic Impact: Public-Private Partnerships models for slum rehabilitation have failed to attract developers due to low commercial viability and regulatory hurdles.
Way Ahead / Solutions
- Holistic Slum Rehabilitation: Integrate housing, infrastructure, livelihood, and social services with community engagement.
- Legal and Institutional Clarity: Streamline land rights, tenure security, and use clear frameworks for slum upgrading.
- Innovative Financing: Utilize Public-Private Partnerships (PPP), Transferable Development Rights (TDR), and micro-financing to fund redevelopment.
- Inclusive Urban Planning: Adapt local models respecting socio-cultural and economic diversity of slum communities.
- Decentralized Infrastructure: Cost-effective sanitation, water, and energy decentralized systems tailored for slum areas.
- Community Participation: Engage slum residents in planning and implementation to ensure acceptance and cultural appropriateness.
