India will need to invest $2.4 trillion by 2050 to protect its rapidly growing cities from intensifying climate threats such as floods, heatwaves, and rising sea levels, according to a World Bank report released Tuesday.
The country’s urban population is projected to nearly double—from 480 million in 2020 to 951 million by 2050—putting immense pressure on housing, transport, water, and waste systems. Without urgent upgrades, the report warns, India could face escalating financial losses from extreme weather events.
“Urban areas need to strengthen resilience to protect their populations,” said Auguste Tano Kouame, World Bank’s India country director, during the report’s launch alongside the Ministry of Housing and Urban Affairs.
Currently, India suffers around $4 billion annually in flood-related damages. This figure is expected to rise to $5 billion by 2030 and soar to $30 billion by 2070 if preventive measures are not taken. Under moderate urbanisation scenarios, the investment requirement could reach $2.8 trillion by 2050 and $13.4 trillion by 2070.
The World Bank emphasised that early and robust investments in resilient, efficient infrastructure—such as flood-resistant housing, climate-smart transit, and sustainable water and waste systems—could save billions each year in avoided losses.
“Prompt measures can save billions annually from flood and heat losses,” the report noted.
India’s current urban infrastructure spending stands at just 0.7% of GDP—well below global norms—necessitating a significant boost in both public funding and private investment. The report urged authorities to align climate-related funding transfers with city needs and to foster greater collaboration with private players in water, sanitation, waste management, and eco-friendly construction.
“Resilient cities are not just a climate imperative; they are an economic necessity for India’s future,” Kouame stressed.
