The relentless heat in India is not just a physical challenge; it's a devastating force pushing the country's poorest workers further into a cycle of poverty. This is the stark reality unveiled by recent research from the International Institute for Environment and Development (IIED), which exclusively shared its findings with The Guardian. The study reveals a disturbing trend: extreme heat acts as a 'poverty multiplier,' exacerbating the struggles of India's informal sector workers, who already face significant economic and social barriers.
One of the most concerning aspects is the impact on outdoor workers, who lost nearly 9% of their salaries in 2024 due to extreme heat. This is a devastating blow, especially considering the already low wages and precarious nature of their employment. The economic loss is most severe in Rajasthan, a region known for its arid climate and rising heat-related deaths. Here, informal workers are losing an equivalent of 8.3% of their income, unable to work due to the grueling effects of extreme heat on their bodies.
The implications are far-reaching. The IIED research estimates that each year, India loses 21.1 working days per person due to extreme heat, an enormous loss for the 550 million workers in the informal sector. This not only affects their immediate income but also has long-term health consequences. Prolonged exposure to heat and dehydration increases the risk of chronic kidney disease, with the IIED estimating that over time, one in 20 informal workers in India could develop this debilitating condition.
What makes this situation even more tragic is that these workers are often socially and economically marginalized, lacking employment security. This means they have little choice but to work through illness and tolerate unsafe conditions, further endangering their health. Access to basic necessities like drinking water, shade, and medical support at worksites is poor, and many return to homes that offer no respite from the heat.
The stories of those affected are heart-wrenching. Take Inder and Laxmi Kumar, a couple working on a construction site in Gurugram. They described feeling like their bodies were on fire, yet they kept working because stopping meant not being paid. They fell ill repeatedly, losing wages and spending their meager income on medicines. Their home, a tarpaulin shelter inside an unfinished building, offers no escape from the heat, with a fan running for just an hour after they return from work.
For female laborers, the burden is even heavier. Many care for young children while working, with little time or energy left for rest. Kumkumari, a 35-year-old construction worker, cools her two-year-old daughter with water, but this doesn't prevent her from falling sick often. When this happens, Kumkumari has to choose between work and caring for her child, further impacting her income.
The heat's impact on health is profound. Sattavir, a 38-year-old laborer, developed a kidney infection after working in extreme heat and suffering repeated dehydration. He now faces a difficult choice: rest and recover, or continue working to pay off his mounting medical debts, despite doctors' advice.
This crisis is not limited to India. Human-caused climate breakdown is intensifying heatwaves worldwide, and India, with its predominantly informal economy, could be one of the first places where heatwaves push human survivability to its limit. The economic cost is estimated to be at least £58 billion, a staggering 2% of India's GDP, due to lost wages, worksite closures, and long-term health issues.
As we consider these findings, it's crucial to recognize the broader implications. Extreme heat is not just a physical challenge; it's a social and economic justice issue. It exacerbates existing inequalities, pushing the most vulnerable further into poverty and compromising their health. Addressing this crisis requires not just climate action but also a reevaluation of labor rights and social safety nets to protect those most affected by climate change.
In my opinion, this research serves as a stark reminder of the human cost of climate change and the urgent need for comprehensive solutions that consider both environmental and social justice.
