Heatwave impacts on South Asian economies

A mid‑July report highlighted how rising temperatures were already straining Indian workers and the British economy. It warned that heat stress could erase more than 19 working days per Indian worker each year by 2030, pushing millions toward poverty, while the United Kingdom faced billions of pounds in lost output from a June 2026 heatwave. The report urged national temperature limits, heat‑insurance schemes and large‑scale cooling and greening investments.

Two weeks later, a World Bank analysis expanded the scope to the whole South Asian region, estimating that extreme heat now costs the equivalent of 31 million full‑time jobs annually and could shrink the regional economy by nearly 7 % by 2050 if trends continue. A separate scientific study warned that a 1 °C rise could cut Indian rice yields by 6.6 %, with similarly sharp declines projected for Pakistan, Bangladesh and neighboring countries. Both documents called for heat‑resilient city planning, sustainable cooling, early‑warning systems and stronger protection for vulnerable workers and agricultural producers.

A subsequent World Bank report in August reinforced these concerns, projecting city‑specific job losses such as 266,000 positions in Delhi by 2030 rising to 418,000 by 2050, with comparable impacts in Kolkata, Mumbai and Chennai. Temperatures at Delhi’s airport could near 50 °C, threatening airline operations and exposing public‑transport users to greater heat stress. Rising cooling demand is already straining electricity networks, with a 15 % jump in power use in May 2024 and a 34 % year‑on‑year increase in air‑conditioner sales. A five‑day heatwave was linked to roughly 30,000 excess deaths, underscoring the growing health burden.
