India’s burgeoning urban centres, poised to become the epicentre of national economic growth, face a critical juncture. A stark new report from the World Bank, developed in collaboration with the Ministry of Housing and Urban Affairs, reveals that this vast potential is under severe threat from escalating climate change impacts, particularly extreme heat and relentless urban flooding. The analysis underscores an urgent imperative: India’s cities must rapidly transition towards green and climate-resilient infrastructure to secure their future prosperity and the well-being of their burgeoning populations.
By 2030, a staggering 70% of new jobs in India are projected to emerge from its urban areas. However, without substantial and immediate investments in climate adaptation and mitigation, these economic engines risk incurring annual losses amounting to billions of dollars, while the livelihoods of millions stand precariously on the brink. This challenge, while immense, also presents an unparalleled opportunity to sculpt a new paradigm of urban development, one that prioritises sustainability and equity.

Auguste Tano Kouamé, World Bank Country Director for India, articulated the gravity of the situation, stating, “The imperative for India to build resilient cities at scale is clear. By investing in more green and resilient urban development—including housing, transport, and municipal services—cities can better mitigate extreme heat conditions and urban floods, and continue to grow and create jobs.” This perspective reframes climate action not as an expense, but as a strategic investment in long-term economic stability and human flourishing.
India’s urban population is on a trajectory to nearly double from 480 million today to a staggering 951 million by 2050. This demographic explosion necessitates the construction of over 144 million new homes by 2070. Concurrently, cities are battling the intensifying urban heat island effect, with city centres experiencing temperatures 3 to 4 degrees Celsius higher than surrounding rural areas. This alarming trend, exacerbated by unchecked urban expansion reducing vital green cover and natural drainage, amplifies cities’ susceptibility to pluvial, or rain-related, floods.
Detailed assessments of 24 cities, including key hubs like Chennai, Indore, New Delhi, Lucknow, Surat, and Thiruvananthapuram, reveal the tangible benefits of proactive climate adaptation. The report estimates that up to $5 billion in flood-related annual losses could be averted by 2030, a figure that could surge to $30 billion by 2070 if comprehensive adaptation measures are not adopted. Furthermore, such interventions could save over 130,000 lives from heat-related fatalities by 2050, underscoring the profound human cost of inaction.
With over half of India’s projected 2050 urban infrastructure yet to be built, the nation possesses a unique and time-bound opportunity to embed resilience at the very foundation of its urban fabric. The World Bank strongly advocates for targeted adaptation programmes, including urban heat mitigation strategies such as cool roofs and expanded green spaces, alongside robust stormwater regulation and advanced early warning systems for both floods and heat waves. Investment in climate-resilient infrastructure—encompassing energy-efficient housing, robust urban transport, and modernised solid waste management promoting a circular economy—is deemed paramount.
Crucially, the report emphasises the need to bolster urban finance by actively engaging the private sector through innovative public-private partnership models and enhancing the creditworthiness of urban local bodies. The financial scale of this transformation is immense, with estimates suggesting India will require over $2.4 trillion in investment by 2050 for low-carbon, resilient urban infrastructure. Public funds alone are insufficient; private capital mobilisation is therefore not merely an option, but an absolute necessity.
Encouragingly, several Indian cities are already charting a course towards climate resilience. Ahmedabad’s pioneering Heat Action Plan, encompassing early warning systems and labour safety protocols, serves as a national benchmark. Kolkata’s city-level flood forecasting system offers a proactive approach to managing flood risks. Indore’s exemplary solid waste management has not only transformed sanitation but also fostered green employment. Chennai, with its comprehensive Climate Action Plan, is integrating urban development with both adaptation and low-carbon growth based on rigorous climate risk assessments. These examples demonstrate that climate-smart urban planning is not a distant ideal but a tangible reality delivering discernible benefits.
Report co-authors Asmita Tiwari and Natsuko Kikutake underscore the urgency, stating that “Timely interventions will help India’s cities continue to safeguard lives and properties, attract new businesses and jobs, and drive innovation.” The findings reiterate a fundamental truth: India’s urban future is a collective responsibility. As cities expand, so too must their capacity to withstand climate shocks, protect vulnerable populations, and lead the nation towards a truly sustainable and equitable future.
