Building Sustainable and Inclusive Cities in India: Key Challenges and Solutions

India’s cities are growing at a pace the world has rarely seen. With India being one of the fastest-urbanizing countries globally, urban centres are absorbing millions of new residents every year, creating pressure on housing, water, transport, and the environment. The promise of cities lies in opportunity, but the reality often involves congestion, pollution, slums, and deep inequality. Building cities that are both sustainable and inclusive is among the most urgent development challenges of our time.

What sustainable and inclusive cities really mean 🔗

A sustainable city manages its resources, waste, and environment in ways that do not compromise the future. An inclusive city ensures that every resident, regardless of caste, religion, gender, income, or migration status, has access to basic services, opportunities, and dignity. The two ideas are inseparable. A city that ignores its poorest residents cannot truly be sustainable, and a city that destroys its rivers, air, and green cover cannot remain liveable for anyone.

The United Nations Sustainable Development Goal 11 explicitly calls for making cities “inclusive, safe, resilient, and sustainable.” For India, this goal carries enormous weight because the country is expected to add more urban dwellers in the next three decades than almost any other nation.

The challenge of rapid and haphazard urban growth 🔗

Urban growth in India has been swift but disorderly. Towns expand outward without planning, and master plans are often violated by developers, communities, and even government agencies. A review of urban planning practice notes that master plans have often acted as controllers of development rather than promoters of it, leading to unplanned sprawl on city edges and congestion at the core.

Environmental degradation 🔗

Unregulated construction has consumed wetlands, encroached on lakes, and stripped away tree cover. Cities like Bengaluru, once known for moderate weather and greenery, now face soaring summer temperatures and the heat-island effect. Air pollution in Delhi regularly crosses hazardous levels, while rivers in most metros carry untreated sewage and industrial waste. The Ministry of Housing and Urban Affairs reports that nearly 70% of the urban infrastructure India will need by 2047 has not yet been built, which is both a warning and an opportunity.

Slum proliferation and housing shortage 🔗

When formal housing remains unaffordable, the urban poor build their own shelters on whatever land they can find: railway tracks, riverbanks, drainage edges, and steep slopes. The 2011 Census recorded 65 million slum residents, but more recent estimates place the figure at over 100 million, roughly a quarter of the urban population. These settlements lack secure tenure, piped water, toilets, and drainage, and they sit on land that is often the most environmentally hazardous in the city.

Widening inequality 🔗

Cities are engines of economic growth, but the wealth they create is unevenly shared. Gated communities with manicured gardens sit a few kilometres from settlements without toilets. Beyond income, exclusion takes social forms too. Caste continues to influence access to rental housing, religious identity often shapes neighbourhood boundaries, and migrants face discrimination based on language and region. These divisions limit the city’s capacity to function as a space of equal opportunity.

Climate change and the urban poor 🔗

Climate change does not affect all city dwellers equally. The wealthy can buy air conditioners, generators, and flood insurance. The urban poor cannot. They live in tin-roofed homes that turn into furnaces during heatwaves and in low-lying areas that flood during every monsoon.

Flooding and waterlogging 🔗

A worrying study cited in recent reporting found that India has the world’s highest number of slum clusters located in flood-prone areas. Mumbai’s coastal slums face annual flooding and the longer-term threat of sea-level rise. Kolkata’s informal neighbourhoods, built on low-lying land, suffer prolonged waterlogging during heavy rain. The Yamuna floods in Delhi in recent years displaced thousands of riverbank residents who had no alternative shelter to fall back on.

Extreme heat 🔗

Heatwaves have become longer and more intense. Researchers at the Indian Institute of Technology Gandhinagar have warned that short-duration but very intense rainfall events are likely to increase due to warming, overwhelming the country’s already weak stormwater drainage. Concrete-heavy cities with little tree cover trap heat, and informal workers, street vendors, construction labourers, and waste pickers have no choice but to work through the worst hours of the day. According to a study by the Centre for Policy Research cited in international reporting, only 37 Indian cities and states had heat emergency plans at the time of assessment, leaving most urban areas unprepared.

Cumulative vulnerabilities 🔗

Climate impacts rarely arrive alone. Floods bring waterborne diseases, heat triggers respiratory and cardiac problems, and poor air quality weakens immunity. Slum residents often lack health insurance, savings, or political voice to demand redress. A vulnerability assessment of households in Dehradun’s slums found very high overall vulnerability with very low absorptive and coping capacity for the potential impacts of climate change. This pattern repeats across mountain towns, coastal cities, and dense inland metros.

Strategies for resilient and inclusive urban growth 🔗

The picture is challenging but not hopeless. Solutions exist, and many are already being tested in Indian cities. What is needed is scale, consistency, and political commitment.

Inclusive housing and tenure security 🔗

Affordable housing is the foundation of an inclusive city. The Pradhan Mantri Awas Yojana – Urban has grounded 114 lakh houses for construction with over 84 lakh delivered, and the programme has been expanded to support an additional one crore urban families. Such schemes must be paired with secure land tenure so that residents can invest in their homes without fear of eviction. Affordable Rental Housing Complexes, launched in 2020, target migrant workers who form the backbone of urban economies but rarely qualify for ownership schemes.

Climate-resilient infrastructure 🔗

Storm drains, sewage systems, and water supply networks need a complete overhaul. The Atal Mission for Rejuvenation and Urban Transformation focuses on water, sanitation, parks, and non-motorised transport across hundreds of cities. Examples like Chennai’s lake restoration and Surat’s coastal protection show how blue-green infrastructure, natural drainage, wetlands, and tree corridors can reduce flood risk while cooling neighbourhoods. Replacing inefficient streetlights and water pumps with energy-saving alternatives has already cut significant carbon emissions under government programmes.

Public transport and walkable design 🔗

A sustainable city moves people, not just vehicles. Investments in metro rail, bus rapid transit, footpaths, and cycling lanes reduce emissions and make cities more equitable, since the poor depend disproportionately on public transport. Transit-oriented development, which concentrates housing and jobs around transit hubs, can curb sprawl and shrink commute times.

Community participation and women’s leadership 🔗

Top-down planning has limits. Residents understand local risks better than distant officials. In Ahmedabad, the Mahila Housing Trust has trained women as Climate Saathis to advocate cooling roofs and energy-efficient solutions in slum settlements, and to interact directly with local authorities. Such grassroots models prove that inclusion is not charity but a practical strategy for resilience.

Stronger urban local bodies 🔗

Municipal corporations carry the weight of service delivery but often have weak finances and limited staff. The 74th Constitutional Amendment empowered urban local bodies, but devolution remains incomplete. Strengthening their revenue base through property tax reform, credit ratings, and municipal bonds, while building technical capacity, is essential. Without capable city governments, no national scheme can succeed on the ground.

Data, technology, and smart governance 🔗

The Smart Cities Mission introduced Integrated Command and Control Centres in many cities, helping monitor traffic, water supply, and emergencies. Aligning urban policy with SDG 11 principles requires combining such technology with equity audits so that data-driven decisions do not bypass informal settlements, which are often invisible in official maps.

The road ahead 🔗

Indian cities stand at a turning point. The next two decades will determine whether they become engines of shared prosperity or hotspots of inequality and environmental stress. The choices made today, about where to build, whom to include, and how to plan for a warmer planet, will shape life for hundreds of millions of people. Sustainability and inclusion are not competing goals; they reinforce each other. A city that protects its poorest residents from heat and floods is also a city that has invested in green cover, public transport, and resilient infrastructure for everyone.

What do you think? Should Indian cities prioritise upgrading existing slums in place, with secure tenure and improved services, or focus on relocating residents to planned affordable housing further from the city core? And how can young professionals, students, and residents push their own city governments to take climate vulnerability of the urban poor more seriously?
