Q.Describe the problem of slums in India.

Concept: Urban Waste Management Issues

Slums in India arise from rapid, unplanned urbanisation and rural-to-urban migration. Key problems include:

1. Overcrowding and Lack of Basic Services – Slums have extremely high population density with inadequate water supply, sanitation, and electricity. This leads to open defecation and untreated sewage.
2. Poor Housing and Legal Insecurity – Dwellings are makeshift (kutcha) and often on encroached land, making residents vulnerable to eviction and disinvestment by authorities.
3. Health and Environmental Hazards – Lack of waste collection creates garbage piles, breeding grounds for disease vectors. Air and water pollution are severe, causing high rates of respiratory and waterborne illnesses. …

The problem of slums in India is not simply a housing shortage — it is a deeper failure of urban planning and governance to keep pace with the demographic shift from villages to cities. To understand why slums exist and persist, you need to see the forces that create them.

1. Rural push and urban pull. Millions of people leave agriculture every year because small farms are no longer viable — fragmented landholdings, erratic monsoons, and low crop prices push them out. At the same time, cities offer the promise of construction work, domestic help, factory jobs, or street vending. This is not a trickle; it is a flood. India’s urban population grew from about 18% in 1960 to over 34% today, and the absolute numbers are staggering.

2. The housing supply simply does not exist. A migrant family arriving in Mumbai or Delhi earns ₹8,000–12,000 per month. A legal one-room tenement in a formal colony costs at least ₹5,000–8,000 in rent — before food, school fees, or medical expenses. The formal housing market (both rental and ownership) is priced for the middle class and above. There is no affordable housing stock for the urban poor. So where do they live? They build their own shelter on vacant land — a railway verge, a riverbank, a garbage-filled low-lying plot — and a slum is born.

3. Slums are defined by what they lack. The Census of India and the National Sample Survey Office (NSSO) define a slum as a compact settlement of at least 20 households with inadequate housing, poor ventilation, and a lack of basic services. The key deficits are:

   • No legal tenure — the land is often government-owned or disputed, so residents live under constant threat of eviction.
   • No piped water — families queue at a single public tap or buy water from private tankers at 5–10 times the municipal rate.
   • No sewerage — open drains, shared pit latrines, or simply open defecation.
   • No electricity connection — illegal hookups or none at all.
   • No solid waste collection — garbage piles up in narrow lanes, breeding disease.

   These are not just inconveniences; they are public health emergencies. Diarrhoea, typhoid, dengue, and respiratory infections are endemic in slum populations.

4. The numbers are enormous and growing. According to the 2011 Census, over 65 million Indians lived in slums — roughly 17% of the urban population. That number is certainly higher today. Mumbai’s Dharavi alone houses over 700,000 people in 2.1 square kilometres — a density of nearly 335,000 per km². But slums are not just a Mumbai phenomenon; every major city — Delhi, Kolkata, Bengaluru, Hyderabad, Chennai — has sprawling slum clusters.

5. Why don't governments just build housing? Several reasons compound the problem:

   • Land is astronomically expensive in Indian cities. Acquiring it for public housing is politically and financially difficult.
   • Slum rehabilitation schemes (like the Pradhan Mantri Awas Yojana – Urban) exist, but they are slow. In-situ redevelopment requires negotiating with multiple stakeholders, and many projects stall for years.
   • Corruption and leakage — funds meant for slum improvement often do not reach the intended beneficiaries. …
