Escalating heat levels are draining South Asia of output equivalent to nearly 31 million full-time positions each year and threaten to shrink the regional economy by almost 7 percent by 2050, according to a newly published World Bank study.

As the region anticipates absorbing 280 million additional individuals into its working-age demographic by mid-century, soaring temperatures stand out as a primary hazard to employment generation, labor output and sustained economic expansion.

Titled 'A Liveable Future: Protecting Jobs and Growth from Extreme Heat in South Asia's Cities', the report reveals that around 520 million people in South Asia could encounter dangerous heat exposure for at least one month annually by 2070—a fourfold surge compared to present figures.

The investigation underscores that intense heat waves are already depressing workplace efficiency, disrupting business operations, and weakening the competitive standing of urban hubs across South Asia.

Concurrently, rising temperatures are burdening healthcare networks and essential public infrastructure, while inflicting the harshest impacts on low-income families, informal laborers, women, the elderly, and children.

"South Asia's cities are central to the region's future, but rising temperatures are putting jobs, livelihoods, and economic growth at risk," stated Johannes Zutt, World Bank Vice President for South Asia.

"Building heat-resilient cities is not only about protecting people from rising temperatures. It is about safeguarding jobs, boosting productivity, attracting investment, and ensuring cities continue to drive economic growth. By acting now, countries can build more resilient, competitive, and livable cities that create opportunities for future generations."

Analyzing extreme heat specifically through the dimensions of employment, efficiency, and macroeconomic progress, the study illustrates how climatic shifts degrade performance across workforce sectors, commercial entities, physical infrastructure, public services, and broader metropolitan economies.

The authors assert that extreme temperatures must no longer be handled as temporary seasonal crises, advocating instead for heat adaptation to be treated as a pivotal development mandate woven into urban master planning, infrastructure budgeting, public policy formulation, and private-sector strategies.

To assist policymakers, the publication outlines an actionable framework adaptable through current administrative and financial channels.

Proposed interventions include channeling capital into heat-resistant infrastructure, expanding Heat Action Plans, insulating vulnerable workers, scaling up sustainable cooling solutions, optimizing early warning channels, and leveraging both public and private funds to construct climate-hardened cities.

The report was formulated with technical and financial assistance from the Resilient Asia Program (RAP)—backed by the UK Foreign, Commonwealth & Development Office (FCDO) under its flagship Climate Action for a Resilient Asia (CARA) initiative—alongside support from the World Bank's Global Facility for Disaster Reduction and Recovery (GFDRR) and the City Resilience Program (CRP).

“Across South Asia, extreme heat is destroying livelihoods, impacting public health, depressing productivity, and pushing the most vulnerable further into poverty,” said John Warburton, Climate Resilience Lead for Asia Pacific at the UK FCDO.

“This is a development crisis that calls for sustained action across sectors. That is why the UK government, through our flagship Climate Action for a Resilient Asia programme, is committed to working with the World Bank and other partners to build knowledge, inform policies, and unlock the investment needs in the region to adapt to a warming planet.”

The study emphasizes that practical remedies are already within reach, citing examples across South Asian municipalities where Heat Action Plans, eco-friendly infrastructure, urban forestry, emergency warning mechanisms, and energy-efficient cooling have successfully preserved lives, supported workers, and curbed financial losses.

Scaling these initiatives on a broader level will necessitate fortified governance, streamlined institutional coordination, and heightened capital investments from both public and private entities.

As rapid urban expansion continues throughout South Asia, the immediate policy decisions executed by governments will determine whether cities function as vibrant engines of employment and innovation or become severely constrained by thermal stress.

Strategic spending on heat resilience remains vital to protecting populations, stabilizing national economies, and securing enduring regional prosperity.
