India’s Path to Smart and Sustainable Cities

India’s urban transition is not just an infrastructure challenge but a civic and governance deficit, as highlighted by the latest Economic Survey’s emphasis on a weak citizen–state compact. India's population is expected to surge to 1.7 billion in 2047 with close to 51% of the individuals residing in urban areas, cities will drive nearly 70% of GDP, intensifying sustainability pressures. Yet, issues like unplanned urbanisation, poor waste management and recurring urban flooding reveal gaps beyond funding. Thus, bridging India’s urban challenges will require not merely financial investment, but a fundamental renewal of the citizen state compact through sustainable development, participatory governance, accountability, and behavioural change. 

What Strides have India’s Cities Made towards Achieving Sustainable and Inclusive Development? 

• E-Mobility Transition (Environmental Sustainability): India is aggressively decarbonizing urban transit by pivoting to electric mobility, significantly curbing greenhouse gas emissions and improving urban air quality.  
  • This mass transition democratizes green transport, ensuring sustainable commuting remains economically accessible to lower-income demographics relying on public transit.  
  • For instance, The PM-eBus Sewa initiative is actively deploying 10,000 electric buses across 169 cities to bridge regional transit gaps.  
    • Additionally, according to the RMI-NITI EV Report, government ambitions for 2030 include 70% EV penetration for commercial vehicles. 
• Affordable Urban Housing (Social Inclusivity): The push for inclusive urbanization has fundamentally transformed slum rehabilitation, integrating marginalized communities into the formal urban economic fabric.  
  • By mandating property ownership for women, these housing initiatives dismantle historical gender-based economic disparities and enhance social security.  
  • With the recent approval of 2.87 lakh additional houses under PMAY-U 2.0, total sanctioned homes have crossed 13.61 lakh, reinforcing the government’s commitment to affordable housing. 
    • Notably, 96% of these houses are registered in the name of women or joint ownership, highlighting a strong focus on women’s empowerment. 
• Circular Waste Economy (Sanitation & Sustainability): Urban sanitation is systematically shifting from linear dumping to a circular waste economy, prioritizing resource recovery, legacy landfill bioremediation, and mechanized segregation.  
  • This systemic overhaul mitigates soil and groundwater contamination while formally integrating the informal waste-picker economy for inclusive, dignified growth.  
  • Swachh Bharat Mission-Urban 2.0 is aiming to make cities 'Garbage Free', actively clearing massive legacy dumpsites like Ghazipur in Delhi.  
    • Consequently, India's urban solid waste processing capacity has jumped to over 80.31% as of late 2025. 
• Decentralized Solar Energy (Climate Resilience): Indian cities are rapidly decentralizing their energy grids by incentivizing rooftop solar installations, fostering energy independence and climate resilience at the household level.  
  • This green energy democratization shields vulnerable urban residents from volatile electricity tariffs while sharply reducing the civic carbon footprint.  
  • The PM Surya Ghar: Muft Bijli Yojana, the world’s largest domestic rooftop solar initiative, is transforming India’s energy landscape with a bold vision to supply solar power to one crore households by March 2027..  
    • This directly subsidizes up to 300 units of free electricity per month, while cutting megatons of carbon emissions. 
• Street Vendor Financial Inclusion (Economic Inclusivity): Urban economic policies have innovatively recognized street vendors as vital micro-entrepreneurs, providing them unprecedented access to formal credit and digital ecosystems.  
  • This paradigm shift protects vulnerable informal workers from exploitative moneylenders, seamlessly integrating them into the core of India’s digital urban economy.  
  • Through the PM SVANidhi scheme, as of July, 2025, over 96 lakh loans amounting to ₹13,797 crore have been disbursed to more than 68 lakh street vendors. 
• Data-Driven Urban Governance (Tech & Sustainability): Urban governance has become radically data-driven through centralized tech hubs that optimize municipal services, disaster response, and dynamic traffic management.  
  • Under the Smart Cities Mission, 100 Integrated Command and Control Centers (ICCCs) have been fully operationalized. 
  • These centres act as the "brain and nervous system" of the cities, centralising data from diverse sources such as traffic sensors, water SCADA systems, and CCTV to improve urban governance. 
    • For instance, cities like Chandigarh have reported millions of e-challans issued through these systems, significantly aiding enforcement. 
• Urban Water Security (Resource Sustainability): Addressing critical urban water stress, cities are aggressively expanding piped water networks and rejuvenating vanishing urban aquifers and historical waterbodies.  
  • This holistic water governance eliminates the daily water-fetching burden primarily borne by women, while climate-proofing vulnerable cities against severe droughts and localized floods.  
  • The AMRUT 2.0 mission is executing a ₹2.77 lakh crore plan to provide tap connections, aiming for universal water supply in 4,378 statutory towns.  
    • Also, Mission Amrit Sarovar is a flagship initiative aimed at creating or rejuvenating at least 75 water bodies (ponds) in every district across India. 
• Rapid Mass Transit Expansion (Spatial Inclusivity): India is executing one of the world's largest expansions of rapid mass transit systems, fundamentally decongesting urban sprawls and connecting peripheral low-income suburbs to central economic hubs.  
  • These high-capacity, low-emission rail networks reduce the spatial inequality of urban geographies, granting equitable and swift mobility to the urban workforce.  
  • India's operational metro network has soared from 248 km across 5 cities (in 2014) to 1,013 km across 23 cities by May 2025. 
    • For instance, the newly operational Delhi–Meerut RRTS corridor recorded its highest single-day ridership of over 1 lakh (100,000) passengers in February 2026. 

What Constraints Hinder India’s Effective Transition Towards Sustainable Urbanization? 

• Municipal Financial Starvation: Indian municipalities suffer from chronic fiscal incapacitation, severely limiting their capital expenditure for sustainable, long-term infrastructure projects.  
  • This over-reliance on state and central transfers undermines local democratic accountability and makes proactive urban planning nearly impossible.  
  • Municipal revenues account for a mere 1% of India's GDP, starkly lower than Brazil's 7% and South Africa's 6% 
    • Furthermore, property tax collections remain heavily under-realized, capturing only about 0.15%-0.20% of GDP despite recent digitization efforts across major metropolises. 
• Fragmented Institutional Governance: Urban administration is crippled by overlapping jurisdictions and powerful, unelected parastatal agencies that frequently bypass elected municipal corporations.  
  • This severe institutional fragmentation prevents cohesive master planning and deeply delays critical sustainability and resilience interventions. 
  • For instance, in Bengaluru, urban governance is fragmented across agencies like BBMP (municipal services), BDA (planning), BWSSB (water), and BMTC (transport), with no unified metropolitan authority. 
  • Similarly, in Mumbai, many agencies share overlapping responsibilities, leading to coordination failures, as noted in the NITI Aayog Strategy for New India @75. 
• Unregulated Peri-Urban Sprawl: Haphazard horizontal expansion beyond formal city limits leads to the rapid growth of "census towns" that lack basic civic amenities and ecological safeguards.  
  • This horizontal sprawl locks in high-carbon commuting patterns and aggressively consumes crucial agricultural lands and wetland buffers.  
  • At the national level, land under non-agricultural use rose from 18.3 to 26.9 million hectares (1991–2022), while net sown area declined by about 1.8 million hectares despite rapid population growth.  
    • The sharpest reductions are seen in states like Punjab, Haryana, Uttar Pradesh, Maharashtra, Tamil Nadu, and Karnataka, particularly in peri-urban areas around major cities such as Delhi NCR, Mumbai, Bengaluru, Hyderabad, and Chennai, where built-up expansion has been most intense.  
• Climate Resilience Deficit: Decades of rampant concretization over natural drainage systems have severely compromised urban climate resilience, turning extreme weather events into recurrent civic disasters.  
  • A reactive rather than predictive approach to climate adaptation leaves vulnerable populations exposed to compounding flood and heatwave risks.  
  • For instance, a recent mapping exercise by the Tamil Nadu Wetland Mission found that over 40% of the 21.25 sq km marshland is encroached, with 8.66 sq km under illegal occupation.  
    • Similarly, about 57% of Indian districts, home to 76% of India's total population, are currently at 'high' to 'very high' heat risk. (CEEW) 
• Chronic Housing Informality: The persistent shortfall in affordable, formalized housing forces a massive influx of migrants into vulnerable informal settlements with highly precarious land tenure.  
  • This deepens spatial inequality, making the equitable distribution of green energy, piped sanitation, and climate-proofing structurally impossible.  
  • An estimated 65 million Indians currently reside in slums, constituting over 17% of the nation's total urban population. (Census 2011) 
    • Despite massive government allocations, the urban housing shortage persists, driven largely by speculative urban land markets. 
• Imbalanced Mobility Paradigms: Urban transport planning disproportionately prioritizes private vehicle infrastructure over non-motorized transport (NMT) and last-mile public transit connectivity.  
  • This systemic bias institutionalizes high vehicular emissions and actively penalizes the economically weaker sections that rely on walking or cycling.  
  • Personal vehicles dominate urban mobility in India, accounting for over 88% of the 25.5 million vehicles registered in 2024–25, mainly two-wheelers and cars. 
    • Modal share data shows personal transport at 35–45%, while public transport remains low at around 25%, with intermediate public transport contributing about 10%. 
• Unsustainable Water Resource Management: Cities are trapped in a vicious cycle of over-extracting groundwater and mismanaging surface water, leading to acute, localized water scarcity.  
  • Fragmented governance is accelerating deep-aquifer depletion and increasing urban vulnerability to climate-induced water shocks, turning routine dry spells into crises.  
  • The 2024 water crisis in Bengaluru highlighted this, with nearly 6,900 of 13,900 borewells drying up before peak summer. 
• Linear Waste Management Bottlenecks: Despite policy pushes for circularity, urban waste infrastructure remains structurally constrained by poor source segregation and inadequate decentralized processing facilities.  
  • The continued reliance on centralized landfilling pollutes peri-urban ecosystems and generates massive, unregulated methane emissions.  
  • India generates over 1.5 lakh tonnes of municipal solid waste (MSW) per day, but only 83% of waste is collected and less than 30% is treated. 
    • Legacy landfills like Ghazipur in Delhi continue to span hundreds of acres, acting as severe biological hazards and major greenhouse gas emitters. 

What Measures are Required to Further Propel India Towards Sustainable Urbanization? 

• Transit-Oriented Development (TOD) and Compact Urbanism: Cities must adopt high-density, mixed-use zoning around mass transit nodes to reduce the necessity for long-distance motorized travel and private vehicle ownership.  
  • By integrating residential, commercial, and recreational spaces within walking distance of "Metro-lite" or RRTS stations, we can maximize land-use efficiency and reduce the per-capita carbon footprint.  
    • This strategy shifts the urban form from sprawling, car-centric suburbs to "15-minute neighborhoods" that prioritize human-scale mobility and social cohesion. 
• Blue-Green Infrastructure Integration: Urban planning must transition from "grey" concrete-heavy engineering to "Blue-Green" infrastructure that integrates natural water bodies and bioswales into the civic fabric.  
  • Implementing "Sponge City" concepts, such as permeable pavements, urban forests, and rejuvenated floodplains, allows cities to naturally absorb storm-water, recharging depleted aquifers while mitigating the urban heat island effect.  
    • This nature-based solution provides a dual benefit of climate resilience against flash floods and the creation of cooling "green lungs" for dense populations. 
• Decentralized Circular Waste Management: Moving away from massive, centralized landfills, cities should implement ward-level decentralized processing units that focus on hyper-local "Waste-to-Wealth" conversion.  
  • By institutionalizing 100% source segregation and integrating informal waste-pickers into a formalized "Circular Economy," cities can convert organic waste into bio-methane and recyclables into industrial feedstock.  
    • This reduces the logistical emissions of transporting waste across cities and prevents the ecological hazards associated with legacy dump-sites. 
• Municipal Bond Markets and Fiscal Autonomy: To fund green infrastructure, Urban Local Bodies (ULBs) must move beyond government grants by strengthening their balance sheets to access the "Green Municipal Bond" market.  
  • Enhancing fiscal autonomy through ring-fenced property tax reforms and value-capture financing allows cities to independently fund climate-resilient projects like renewable energy grids and EV charging hubs. 
    •  A credit-worthy municipality can attract private institutional capital, ensuring that sustainable transitions are not stalled by state-level budgetary constraints. 
• Digital Twin Technology for Predictive Governance: Deploying "Digital Twin" technology  (a virtual 3D replica of a city fed by real-time IoT sensors) enables urban planners to simulate and optimize resource distribution, traffic flows, and disaster responses.  
  • This "Data-Led Urbanism" allows for the predictive maintenance of water pipelines to reduce non-revenue water and the dynamic management of energy grids to balance peak-load demands.  
    • By digitizing the urban commons, governance becomes proactive rather than reactive, significantly enhancing the operational efficiency of city systems. 
• Inclusive In-Situ Slum Redevelopment: Sustainability is impossible without social inclusivity; therefore, cities must prioritize "In-Situ" (on-site) redevelopment of informal settlements rather than peripheral relocation.  
  • By providing tenurial security and integrating vertical social housing with basic piped utilities and green energy, we prevent the creation of "urban deserts" and maintain the proximity of the workforce to economic hubs.  
    • This approach preserves the social capital of the urban poor while upgrading the overall environmental and hygienic standards of the city's densest pockets. 
• Micro-Grid Solarization and Energy Prosumerism: Urban centers should incentivize a transition from passive energy consumers to active "prosumers" through mandatory rooftop solar-hybrid systems on all commercial and high-rise residential buildings.  
  • Creating localized DC micro-grids can provide energy security during grid failures caused by extreme weather while reducing the transmission and distribution losses of the central grid.  
  • This democratization of energy production, supported by net-metering policies, turns every rooftop into a productive green asset, rapidly scaling the city's renewable energy mix. 
• Non-Motorized Transport (NMT) and Complete Streets: Cities must redesign arterial roads into "Complete Streets" that provide dedicated, protected lanes for NMT, such as cycling and walking, alongside public transit corridors.  
  • Prioritizing the "right of way" for pedestrians over private automobiles through traffic calming and tactical urbanism encourages a modal shift that improves public health and air quality.  
  • By treating streets as shared public assets rather than mere conduits for cars, cities can reclaim valuable space for social interaction and green landscaping.

Conclusion:

Sustainable urbanization in India necessitates a paradigm shift from mere brick-and-mortar expansion to a robust "citizen–state compact" rooted in civic trust. By synchronizing fiscal autonomy for local bodies with climate-resilient strategies like the Sponge City model, India can transform its demographic transition into an economic powerhouse. Achieving the 2047 vision requires navigating structural bottlenecks through data-driven governance and inclusive social housing. Ultimately, the future of Indian cities lies in balancing rapid technological modernization with the restoration of ecological and institutional credibility.
