Overview
The World Bank released a report on Friday, 2026 highlighting that extreme heat is already costing South Asia the equivalent of 31 million full‑time jobs each year. If unchecked, the region could see a 7 % reduction in GDP by 2050 despite an expected addition of 280 million working‑age people.
Key Developments
- Heat threatens labour productivity, business continuity and city competitiveness.
- Vulnerable groups – low‑income households, informal workers, women, the elderly and children – bear the brunt.
- By 2070, about 520 million people in South Asia could face at least one month of dangerous heat annually, four times the current figure.
Important Facts
The report, titled “A Livable Future: Protecting Jobs and Growth from Extreme Heat in South Asia’s Cities”, analyses the issue through three lenses – jobs, productivity and economic growth. It shows how rising temperatures affect labour productivity, disrupt supply chains, strain health systems and damage critical infrastructure.
Exam Relevance
Understanding the heat challenge is vital for multiple GS papers. It links to heat‑resilient cities (GS3 & GS4), the design of heat action plans (GS4), and the role of public‑private partnerships in financing adaptation measures (GS3). The need for sustainable cooling also touches on technology and environmental policy.
Way Forward
The report urges that heat should move from a seasonal emergency to a core development priority. Recommended actions include:
- Investing in heat‑resilient infrastructure and retrofitting existing assets.
- Strengthening and scaling up heat action plans at city and state levels.
- Protecting vulnerable workers through labour regulations and social safety nets.
- Expanding sustainable cooling technologies.
- Improving early‑warning systems and public awareness campaigns.
- Mobilising public‑private investment for climate‑smart urban projects.
By acting now, South Asian nations can build cities that are competitive, livable and capable of supporting future generations.
