The Himalayas Are Melting: Why India’s Economy Faces a Growing Threat

The Himalayan mountain range is often called the 'Third Pole' because it holds so much ice. However, new research shows that these mountains are reaching a dangerous point. Glaciers are melting 65% faster than they were a decade ago. This rapid change is not just an environmental problem; it is a major risk to the economy of India and the surrounding region.

A new report by the global group Systemiq, with help from the International Centre for Integrated Mountain Development (ICIMOD) and other research institutes, highlights the scale of the crisis. The report explains that as glaciers melt, they leave behind large lakes held back by unstable rock and ice. These lakes can burst, causing sudden and deadly floods. Recent years have seen tragic examples of this. In 2023, a flood in Sikkim killed at least 70 people and destroyed important roads, bridges, and hydropower projects. In 2021, a similar event in Uttarakhand caused the deaths of more than 200 people.

According to the report, the physical landscape is changing quickly. Warming temperatures are causing permafrost—ground that is usually frozen all year—to thaw. This makes mountain slopes less stable and increases the chance of multiple disasters happening at once. Despite these growing dangers, the report notes a serious gap in monitoring. Out of an estimated 40,000 glaciers in the region, only about 21 are being watched closely on a regular basis.

This situation is particularly worrying because of how much the region relies on Himalayan water. These mountains feed the rivers that support the lives of hundreds of millions of people across South Asia. ICIMOD notes that many river basins are approaching 'peak water.' This is the point when the water flowing from melting glaciers reaches its highest level before it begins to drop as the glaciers lose too much mass. Once this happens, the water supply for farming and energy will likely decrease.

The economic impact is massive. The new research estimates that water from the Himalayas supports roughly 20% of India's GDP, which is the total value of all goods and services produced in the country. This water is essential for growing crops like wheat, rice, and tea, as well as for generating electricity through hydropower. Even though the mountains are vital to the national economy, the mountain states themselves receive only about 5% of that economic value.

Lord Nicholas Stern, an economist from the London School of Economics, emphasized the importance of the region. He noted that unlike the North and South Poles, the Himalayan 'Third Pole' has hundreds of millions of people living directly beneath it. He warned that the natural system supporting this population is approaching a 'tipping point'—a moment when a small change can cause a much larger and irreversible effect. He described the mountains as a form of national and international infrastructure that is now in danger.

The Indian government is aware of the risks. In July, officials told parliament that they had identified 56 glacial lakes as being at 'very high risk' following a 2025 scientific study. The Central Water Commission is currently monitoring nearly 2,500 glacial lakes across the country's Himalayan river basins. While 18% of Indian land is located in the Himalayas, this region accounts for about 35% of the country's disasters, according to the report.

Looking ahead, the challenge for the region is significant. While some of the warming is caused by global factors, the report suggests that not all the forces driving glacier loss are beyond the region's control. As the environment continues to change, the need for better monitoring and stronger safety measures becomes more urgent. For the millions of people who depend on these rivers, the future depends on how quickly governments can adapt to this new, unstable reality.
