Framework: The Indian Urban Challenge
India is in the middle of the largest urban transition in human history. Urbanisation is no longer a demographic statistic — it is the central policy challenge that shapes housing, transport, jobs, climate, water, and even federalism. Chapter 13 of this series mapped the demography of urbanisation; Chapter 14 examined housing and slums. This chapter focuses on the systemic problems of urban living — infrastructure, governance, environment, mobility, poverty — and the policy remedies that attempt to close the gap.
Scale of Urbanisation in India
| Indicator | Figure | Source |
|---|---|---|
| Urban share of population (Census 2011) | 31.16% (377 million) | Census of India 2011 |
| Estimated urban share (UN WUP 2025, Degree of Urbanisation method) | ~40.3% in 2025 | UN DESA, World Urbanization Prospects 2025 |
| Projected urban share by 2050 | >50% (slightly over half the population) | UN WUP 2025 |
| Projected urban addition, 2018–2050 | ~416 million (largest in the world) | UN DESA |
| Share of India's GDP from urban areas | ~60% | HPEC Report, MoHUA |
| Metro cities with 1 million+ population (Census 2011) | 53 | Census of India |
| Urban poor (approximate) | ~80 million (2011 BPL urban) | Tendulkar / Rangarajan estimates |
Key insight: India will add more urban dwellers between 2025 and 2050 than any country has ever added in history. The next quarter-century will decide whether Indian cities become engines of prosperity or sites of systemic stress.
Core Urban Problems — A Summary
| Problem | Scale / Data | Representative Example |
|---|---|---|
| Housing & slums | 17% urban population in slums (Census 2011); ~1.12 crore housing shortage (2012 estimate) | Dharavi (Mumbai), Bhalswa (Delhi) |
| Water stress | 21 cities faced acute stress (NITI Aayog CWMI 2018); Bengaluru shortage ~500 MLD daily in 2024 | Bengaluru 2024, Chennai 2019 "Day Zero" |
| Sanitation | 72% of urban sewage untreated (CPCB 2020-21: 72,368 MLD generated, only 20,236 MLD treated) | Yamuna froth, Musi river in Hyderabad |
| Air pollution | India 5th most polluted country (IQAir 2024); 13 of world's 20 most polluted cities in India | Delhi — world's most polluted capital (PM2.5 = 108.3 µg/m³, 2024) |
| Solid waste | ~62 million tonnes/year urban MSW (CPCB); only 69% collected, only ~37% treated; projected 165 MT by 2030 | Ghazipur, Bhalswa, Deonar landfill fires |
| Urban flooding | Mumbai 2005 (944 mm in 24 hrs), Chennai 2015, Hyderabad 2020, Bengaluru 2022 | Saturation of stormwater drains, loss of lakes |
| Traffic congestion | Bengaluru & Pune routinely in global top-10 worst (TomTom Index) | 2-hour peak commutes become norm |
| Urban heat island | Delhi, Ahmedabad record 48–49°C summers; 2010 Ahmedabad heatwave — 1,344 excess deaths in May alone | Drives Heat Action Plans |
Infrastructure Deficit
India's urban infrastructure lags its population growth by at least a decade:
| Service | Norm / Benchmark | Ground Reality |
|---|---|---|
| Water supply | 135 LPCD (litres per capita per day) — CPHEEO norm for metro cities | Many Tier-2 cities supply <100 LPCD; intermittent supply in most metros |
| Sewerage coverage | Universal coverage expected | Only ~31,841 MLD installed capacity against 72,368 MLD generation (CPCB) |
| Sewage treatment | 100% treatment before discharge | Only ~28% actually treated; 72% discharged untreated |
| Solid waste processing | Segregation at source, 100% processing | ~69% collected, ~37% treated, 50%+ dumped |
| Public transport | 60 buses per lakh population (urban norm) | Indian cities average ~30–40; many have no organised bus service |
| Road density | Planned cities maintain ~20% land under roads | Old quarters of Mumbai/Kolkata <10% |
| Green cover | 20-30% (WHO / URDPFI) | Most metros under 10% |
Urban Governance Structure
Constitutional Foundation — 74th Amendment (1992)
The Constitution (74th Amendment) Act, 1992 came into force on 1 June 1993, inserting Part IXA (Articles 243P–243ZG) and the Twelfth Schedule into the Constitution. It gave constitutional status to urban local bodies.
| Feature | Detail |
|---|---|
| Three-tier urban structure | Nagar Panchayat (transitional area) → Municipal Council (smaller urban) → Municipal Corporation (larger urban) |
| Reservations | SC/ST (in proportion to population); women — not less than one-third (many states have raised to 50%) |
| Term | 5 years; elections must be held before expiry |
| State Election Commission (Art 243ZA) | Conducts all ULB elections |
| State Finance Commission (Art 243Y) | Reviews fiscal position every 5 years |
| Twelfth Schedule | Lists 18 functions ULBs may be entrusted with — urban planning, regulation of land use, water supply, public health & sanitation, fire services, urban forestry, slums, urban poverty alleviation, etc. |
Metropolitan & District Planning
| Body | Article | Function |
|---|---|---|
| Metropolitan Planning Committee (MPC) | Art 243ZE | Mandatory for every metropolitan area (>10 lakh). Prepares a Draft Development Plan coordinating ULBs + panchayats |
| District Planning Committee (DPC) | Art 243ZD | Consolidates plans of panchayats and municipalities in the district |
Implementation gap: Most states have not operationalised MPCs even three decades after the 74th Amendment. Where constituted, they are often advisory and bypassed by powerful parastatals.
The Parastatal Problem
Despite the 74th Amendment, most urban planning and service delivery remains with state-controlled parastatals that dilute ULB autonomy:
| City | Parastatal | Role |
|---|---|---|
| Delhi | DDA (Delhi Development Authority) | Master plan, land, housing |
| Mumbai | MMRDA (Mumbai Metropolitan Region Development Authority) | Regional planning, major projects |
| Bengaluru | BDA (Bangalore Development Authority), BWSSB (water) | Planning, water/sewerage |
| Chennai | CMDA (Chennai Metropolitan Development Authority) | Metropolitan planning |
| Hyderabad | HMDA | Regional planning |
Second Administrative Reforms Commission (2nd ARC) recommended genuine devolution of all 18 functions to ULBs and treating mayors as empowered chief executives — largely unimplemented.
Major Government Missions
| Mission | Launch / Period | Outlay | Key Feature | Status (2025–26) |
|---|---|---|---|---|
| Smart Cities Mission (SCM) | 25 June 2015; closed 31 March 2025 | Central outlay ₹47,652 crore; total project investment ~₹1.64 lakh crore | 100 cities selected via competition; Area-Based Development + Pan-City solutions; SPV execution model | 8,067 projects sanctioned; 7,555 completed (94%) worth ₹1.51 lakh crore; only 18 of 100 cities declared full completion |

| PM e-Bus Sewa | 16 August 2023 | ₹57,613 crore (Central share ₹20,000 crore) | 10,000 e-buses across 116 cities on PPP basis; 10-year operational support | 10,000 buses sanctioned across 116 cities in 20 states + 6 UTs |
Urban Transport
Metro Rail
India's metro network is the third-longest operational metro system in the world:
| Metric | 2014 | 2025 |
|---|---|---|
| Operational route-km | 248 km | ~1,095 km |
| Cities with metro | 5 | 26 |
Major networks: Delhi Metro (~395 km, largest in India), Mumbai, Bengaluru (Namma Metro), Hyderabad, Chennai, Kolkata (India's oldest — 1984), Kochi, Lucknow, Jaipur, Ahmedabad, Nagpur, Pune, Noida.
Bus-based Transit
| Initiative | Detail |
|---|---|
| National Urban Transport Policy, 2006 | Shift focus from "movement of vehicles" to "movement of people"; prioritise public and non-motorised transport |
| BRTS — Successes | Ahmedabad Janmarg (2009) — India's first successful BRT; dedicated corridors, median boarding |
| BRTS — Failures | Delhi BRT (2008) — scrapped 2015 due to design flaws, congestion on mixed-traffic sections |
| PM e-Bus Sewa (2023) | 10,000 e-buses to 116 cities — especially for cities with no organised bus service |
Non-Motorised Transport
Walking and cycling account for 25–40% of urban trips yet receive <1% of urban transport budgets in most cities. The Streets for People Challenge (2020) and India Cycles4Change Challenge (under SCM) attempted course-correction.
Environmental Challenges
Air Pollution
The 2024 IQAir World Air Quality Report placed India as the 5th most polluted country globally (annual PM2.5 = 50.6 µg/m³). Delhi remained the world's most polluted capital for the sixth consecutive year (PM2.5 = 108.3 µg/m³, up from 102.4 in 2023). Byrnihat (Assam–Meghalaya border) topped the global city list at 128.2 µg/m³. In total, 13 of the world's 20 most polluted cities are in India.
National Clean Air Programme (NCAP)
| Feature | Detail |
|---|---|
| Launch | January 2019 (MoEFCC) |
| Coverage | 131 non-attainment cities (including Million-Plus cities) across 24 states/UTs |
| Target (original) | 20–30% PM reduction by 2024 (baseline 2017) |
| Target (revised) | Up to 40% PM10 reduction by 2025–26 (baseline 2019–20), or attain NAAQS |
| Funding | 15th Finance Commission grants to Million-Plus cities tied to air-quality performance |
CREA and CSE assessments (2024–25) find the 2026 target highly unlikely to be met at current pace.
Urban Flooding
A recurring pattern: heavy rainfall + loss of natural drainage + encroached wetlands + poor stormwater networks.
| Event | Year | Impact |
|---|---|---|
| Mumbai deluge (944 mm in 24 hrs) | 26 July 2005 | ~1,000+ deaths; led to Mithi river project |
| Chennai floods | Dec 2015 | Loss of wetlands in Pallikaranai; encroachment along Adyar |
| Hyderabad floods | Oct 2020 | Failure of lake-chain ecosystem |
| Bengaluru floods | Sep 2022 | IT corridor under water; loss of stormwater drains (rajakaluves) |
Blue-Green Infrastructure
Models such as Hyderabad's urban lake chain restoration, Ahmedabad's Sabarmati Riverfront, and Chennai's restoration of Pallikaranai marshland show how integrating water bodies and green spaces reduces flooding, heat, and pollution simultaneously.
Urban Poverty — The Invisible Problem
Urban poverty is often statistically undercounted because slum enumeration misses non-notified settlements, pavement dwellers, and homeless populations.
| Dimension | Issue |
|---|---|
| Measurement gap | Census slum count covers only enumerated areas ≥60 households; pavement dwellers, single-room rentals, and peri-urban poor are invisible |
| Informal employment | Over 80% of urban workers in informal sector; no social security, no minimum wage enforcement |
| Street vendors | ~1 crore urban vendors; Street Vendors Act 2014 mandates Town Vending Committees — poorly constituted; PM SVANidhi provides micro-credit |
| Migrant workers | 2020 COVID-19 lockdown exodus revealed absence of portability of welfare; One Nation One Ration Card (ONORC) partial remedy |
| No urban MGNREGA | Unlike rural MGNREGA guarantee, no universal urban employment guarantee; Kerala's Ayyankali Urban Employment Guarantee Scheme (AUEGS, 2010) and Odisha's MUKTA are state-level experiments |
Sustainability & Climate Action
| Initiative | Detail |
|---|---|
| C40 Cities | Indian members — Mumbai, Delhi NCT, Bengaluru, Kolkata, Chennai, Jaipur — commit to climate action aligned with 1.5°C pathway |
| India Cooling Action Plan (ICAP), 2019 | World's first such national plan; target — reduce cooling demand 20–25% by 2037–38, refrigerant demand 25–30%, cooling energy 25–40% |
| Ahmedabad Heat Action Plan (HAP), 2013 | First HAP in South Asia (after the 2010 heatwave that caused 1,344 excess deaths in May alone); has since saved an estimated 1,190 lives/year. Template now extended to 23 states and 100+ cities |
| Climate-Smart Cities Assessment Framework | Under MoHUA (2019, 2.0 in 2021) — climate-sensitive evaluation of cities |
| State Action Plans on Climate Change (SAPCCs) | All states have SAPCCs with urban components |
Smart Urban Planning Paradigms
| Paradigm | Core Idea | Indian Application |
|---|---|---|
| Transit-Oriented Development (TOD) | High-density, mixed-use development within 500m–800m of transit stations | Delhi TOD Policy (2015, 2019); MoHUA National TOD Policy 2017 |
| 15-minute city | Every daily need within 15-min walk/cycle; Paris (Carlos Moreno) | Pune, Chandigarh pilots; Delhi MPD-2041 draft |
| Master Plan / MPD-2041 | Statutory 20–25 year spatial plan; land use, FAR, infrastructure | Delhi Master Plan 2041 (draft); Mumbai DP 2034; Bengaluru RMP 2041 |
| FAR / FSI reform | Rationalise Floor Area Ratio near transit, allow vertical growth | Mumbai DP-2034 raised FSI; TOD zones raised FAR |
| Land Value Capture (LVC) | Finance infrastructure via tax on uplift in land values | Betterment levy, TDR, premium FAR — used piecemeal by MMRDA, DDA |
Case Studies — Success and Failure
| Case | Year | Lesson |
|---|---|---|
| Surat Plague → Model City | 1994 (plague) → 2000s | Post-plague leadership (Commissioner S.R. Rao) transformed Surat into one of India's cleanest cities; Swachh Survekshan joint #1 (2023) |
| Indore — Swachh Champion | 2017 onwards | India's cleanest city for 7 consecutive years (2017–2023). Source segregation at 100%, door-to-door collection, bio-CNG plants. Now in "Golden Club" non-competing category |
| Chennai Water Reset | 2019 "Day Zero" → 2020 | Rainwater harvesting drive (made mandatory since 2003), lake restoration, Veeranam link revived; 2021 monsoon surplus |
| Bengaluru Water Crisis | Summer 2024 | 6,900 of 13,900 borewells dry; ~500 MLD daily shortfall; loss of 80% of city's 1,452 historic water bodies — demonstrates planning failure |
| Delhi Air Pollution | Ongoing | Despite CAQM (2021), GRAP, odd-even — no structural improvement; airshed approach still pending |
| Delhi BRT Failure | 2008–2015 | Poor design, no bus-lane enforcement, political backlash; scrapped |
| Ahmedabad Janmarg | 2009 onwards | India's first successful BRT; dedicated corridor, station design; adopted as template |

Recent Developments (2024–2026)
PMAY-Urban 2.0 — New Housing Architecture (September 2024)
The government launched PMAY-Urban 2.0 in September 2024, targeting construction of 1 crore additional houses for the urban poor over 5 years with ₹2.30 lakh crore in central assistance. Unlike PMAY-U 1.0 (2015–2024, ~1.18 crore sanctioned), PMAY-U 2.0 introduces a dedicated affordable rental housing component to address the accommodation crisis for migrant workers — a gap made visible by the COVID-19 lockdown-era reverse migration of ~10 million workers. The EWS category (income below ₹3 lakh/year) receives the highest subsidy under the Credit Linked Subsidy Scheme (CLSS). A persistent implementation challenge: PMAY-U requires land title, excluding approximately 6 crore slum dwellers who occupy land without tenure. States with the highest unmet urban housing demand — Maharashtra, UP, Karnataka, Tamil Nadu — must now integrate PMAY-U 2.0 with state-level slum rehabilitation authorities and RERA for project quality oversight.
UPSC angle: Prelims — PMAY-U 2.0 September 2024; 1 crore houses; affordable rental housing component; CLSS for EWS. Mains (GS1/GS2/GS3) — urban housing deficit and the exclusion of the landless urban poor; rental housing market failure; RERA and housing quality governance; 74th Amendment and ULB role in slum rehabilitation.
Smart Cities Mission Concluded — Lessons for Urban Governance (March 2025)
The Smart Cities Mission was officially concluded on 31 March 2025. Of 8,067 projects, 7,555 (94%) were completed with ₹1,51,361 crore invested. Key infrastructure outputs: 100 Integrated Command and Control Centres (ICCCs); smart street lighting in 80+ cities; fibre optic connectivity in central business districts; improved surveillance systems. Evaluation findings by MoHUA: (i) the SPV (Special Purpose Vehicle) model — creating a parallel body alongside the elected ULB — improved project speed but created a governance deficit (SPV has no democratic mandate, limited accountability); (ii) smart infrastructure benefits were concentrated in central and business districts, with limited impact in peripheral slums; (iii) sustainable operation requires mainstreaming into municipal budgets, which most cities struggle to do. AMRUT 2.0 (2021–26, ₹2.77 lakh crore) continues with a focus on universal water supply and sewerage — addressing more fundamental urban infrastructure needs than the Smart Cities Mission.
UPSC angle: Prelims — Smart Cities Mission concluded March 31, 2025; 94% projects completed; 100 ICCCs; AMRUT 2.0 ₹2.77 lakh crore. Mains (GS2) — SPV model and democratic accountability; why ULBs remain weak despite missions; 74th Amendment 12th Schedule devolution gap; comparison of Smart Cities vs AMRUT approaches to urban development.
Urban Air Pollution and Delhi's AQI Crisis (2024–2025)
India continues to host the world's most polluted cities — IQAir's World Air Quality Report 2024 ranked India the world's 3rd most polluted country (average PM2.5: 50.6 µg/m³ vs WHO guideline of 5 µg/m³). Delhi, Byrnihat (Assam), and Begusarai (Bihar) featured among the world's most polluted cities. The Commission for Air Quality Management in NCR and Adjoining Areas (CAQM) — a statutory body under the CAQM Act 2021 — issued Stage III and IV GRAP (Graded Response Action Plan) restrictions multiple times during winter 2024-25, including bans on diesel trucks entering Delhi, construction halts, and school closures. However, the Supreme Court's monitoring of Delhi air quality revealed implementation gaps: CAQM orders routinely not enforced at the state level. Urban air pollution exacerbates health inequalities — slum dwellers, street vendors, and outdoor workers have disproportionate exposure, while wealthy households can afford air purifiers and sealed workplaces.
UPSC angle: Prelims — IQAir 2024: India 3rd most polluted; CAQM Act 2021; GRAP Stage I/II/III/IV; Delhi PM2.5 average. Mains (GS1) — urban environmental health inequality; air pollution as urban governance failure; CAQM as institutional response; health impact on urban poor; intersection of urbanisation, industrialisation, and air quality.
PMAY-Urban 2.0 — Angikaar 2025 Community Mobilisation and 13.61 Lakh Houses (2025–2026)
The Angikaar 2025 campaign was launched under PMAY-Urban 2.0 in 2025 as a community mobilisation initiative targeting first-generation urban settlers and slum dwellers eligible for housing benefits but unaware of the scheme. The campaign addresses a persistent implementation failure: millions of eligible beneficiaries in urban slums do not apply for PMAY because of documentation challenges (lack of land title, Aadhaar-address mismatch, etc.). By early 2026, PMAY-U 2.0 had sanctioned 13.61 lakh houses, with the 4th CSMC meeting (August 2025) approving an additional 1.47 lakh houses across 14 states/UTs.
The Economic Survey 2025-26 specifically flagged long-standing supply-side constraints in urban land, housing, and transport as key sources of urban stress limiting India's economic potential — explicitly noting that excessive Floor Space Index (FSI) restrictions in Indian cities (typically 1.5–2.5, vs 8–12 in comparable Asian metros) artificially constrain housing supply, inflate property prices, and push the poor to urban peripheries with poor connectivity. The Survey recommended FSI liberalisation, transit-oriented development (TOD), and metropolitan-level land pooling as priority urban reforms.
UPSC angle: Prelims — Angikaar 2025 (PMAY-U 2.0 community campaign); 13.61 lakh houses sanctioned (early 2026); Economic Survey 2025-26 urban stress (FSI restrictions); TOD (transit-oriented development). Mains (GS1/GS2) — supply-side vs demand-side housing policy; FSI regulations as cause of unaffordability; urban land reform; Economic Survey 2025-26 urban recommendations.
Exam Strategy
GS1 Mains — Recurring themes:
- "Discuss the major problems of urbanisation in India and suggest measures to make cities more sustainable and inclusive."
- "Examine the social consequences of rapid urbanisation in India."
- "How has the 74th Constitutional Amendment impacted urban governance in India?"
GS2 overlap (highly testable):
- 74th Amendment — devolution, MPC implementation gaps
- Centrally Sponsored Schemes — Smart Cities, AMRUT, PMAY-U outcomes
- Cooperative federalism in urban governance
GS3 linkage:
- Urban infrastructure and economic growth
- Climate adaptation, disaster management (urban floods)
- Pollution and environmental regulation
Conceptual anchors to always cite:
- SDG-11: "Make cities and human settlements inclusive, safe, resilient and sustainable."
- 74th Amendment + 12th Schedule — the constitutional foundation for any urban answer.
- HPEC Report, 2011 — the benchmark citation for urban infrastructure finance.
- Data triangulation — Census 2011 + UN WUP 2025 + IQAir 2024 + CPCB STP report, to sound both authoritative and current.
Answer-writing tip: Always balance problem → policy response → implementation gap → way forward. Avoid listing only schemes; the examiner tests whether you can identify why, despite a decade of missions, Indian cities still flood, choke on smog, and run out of water — the answer almost always returns to unempowered ULBs, weak metropolitan planning, and fragmented parastatals.
