The Himalayas are melting faster - and India's economy is 'at risk'

The latest Systemiq report on the Himalayas paints an increasingly stark picture of a mountain system that is both a vital water source for India and a growing source of disaster risk. Glaciers are losing mass at a rate 65 % faster than a decade ago, glacial lakes are expanding, permafrost is destabilising, and monitoring remains limited to just over half a dozen percent of the roughly 40,000 glaciers that dot the Himalaya‑Karakoram range. The implications for India’s economy, infrastructure and the millions of people who live downstream are profound, and the report outlines a set of priority actions that could blunt the looming crisis.

Accelerating glacier loss and the monitoring gap

The core finding of the Systemiq study, produced with the Integrated Mountain Initiative and technical input from ICIMOD and the GB Pant National Institute of Himalayan Environment, is that Himalayan glaciers are melting markedly faster than they were ten years ago—specifically, 65 % faster. This acceleration is occurring even as the region’s monitoring capacity lags far behind the scale of change. Of the estimated 40,000 glaciers across the Himalaya‑Karakoram, only about 21 are being observed in detail on a sustained basis. The report stresses that this monitoring gap matters because the physical landscape is changing at a speed that outpaces the ability of scientists and policymakers to anticipate hazards.

When glaciers retreat, they leave behind expanding proglacial lakes that are often dammed by loose rock and ice. These natural dams are inherently unstable, and as warming destabilises permafrost and high‑mountain slopes, the likelihood of sudden lake‑outburst floods rises. The report links these processes directly to the growing frequency of cascading hazards, a pattern already evident in recent disasters across the region.

Human cost of glacial lake outbursts

Recent tragedies illustrate the deadly potential of glacial lake outbursts. In 2023, a flood triggered by a bursting lake in Sikkim killed at least 70 people and caused extensive damage to roads, bridges and hydropower infrastructure. A similar event in Uttarakhand in 2021 resulted in more than 200 fatalities as floodwaters surged through the Rishiganga and Dhauliganga valleys. These incidents underscore the report’s warning that “millions of lives and livelihoods” are hanging in the balance as the Himalayas approach a tipping point.

The human toll is compounded by the broader vulnerability of the region. The report notes that while Himalayan land makes up roughly 18 % of India’s total area, it accounts for about 35 % of the country’s disaster burden. This disproportionate exposure reflects both the concentration of hazard‑prone terrain and the dense settlement of downstream communities that rely on mountain water for agriculture, energy and daily life.

Economic dependence on Himalayan water

Beyond the immediate disaster risk, the Himalayas underpin a substantial share of India’s economy. Systemiq estimates that water originating from the mountain range supports roughly 20 % of India’s gross domestic product, feeding key sectors such as wheat, rice, tea, hydropower and pilgrimage tourism. Yet the mountain states themselves capture only about 5 % of that value, highlighting a stark disparity between the region’s contribution to national wealth and the benefits that accrue locally.

ICIMOD warns that “peak water” – the point at which glacier runoff reaches its maximum before declining – is expected around mid‑century for most Hindu Kush Himalayan basins. As glaciers continue to lose mass, the timing and volume of runoff will shift, potentially threatening agricultural cycles, energy generation and water security for hundreds of millions of people across South Asia.

Black carbon as a controllable driver

The report identifies black carbon – soot deposited on snow and ice – as a significant, and potentially controllable, accelerator of glacier melt. Roughly one‑third of the observed melt is attributed to black carbon, much of which originates from brick kilns in the Indian plains. Because black carbon is a short‑lived pollutant, unlike long‑lived greenhouse gases, policy measures that curb its emissions could have an immediate impact on glacier health.

Systemiq argues that India and its neighbours have a direct lever to reduce this source of warming. Targeted interventions in the brick‑kiln sector, alongside broader air‑quality measures, could therefore serve as a pragmatic component of the region’s climate‑adaptation strategy.

Priority transitions for resilience

To address the intertwined challenges of glacier loss, disaster risk and economic vulnerability, the report outlines ten priority transitions. Two of these are highlighted in the article: strengthening disaster preparedness and rethinking tourism. Strengthening preparedness involves pre‑negotiated actions—such as evacuation protocols and infrastructure protection—when hazards emerge, thereby reducing loss of life and property.

Tourism, which draws roughly 400 million visits a year to the Indian Himalayas, is another focal point. The report suggests shifting the sector’s emphasis from sheer visitor numbers toward generating value that is retained and reinvested locally. Such a shift could help balance economic benefits with the environmental pressures that tourism places on fragile mountain ecosystems.

Cross‑border cooperation as a necessity

Given that the Himalayas span multiple national jurisdictions, the report stresses that no single country can manage the emerging risks alone. Pema Gyamtsho, director‑general of ICIMOD, notes that “hazards do not respect national borders,” and calls for shared monitoring, risk information and early‑warning systems. Joint investment in resilience, he argues, is essential not only for saving lives but also for safeguarding the livelihoods of hundreds of millions who depend on the mountains.

India’s Central Water Commission is already monitoring 2,485 glacial lakes larger than 10 hectares across the country’s Himalayan river basins, and the government has classified 56 lakes as “very high risk” following a 2025 scientific assessment of 189 high‑risk lakes. These steps illustrate an emerging framework for cross‑border data sharing, but the report suggests that scaling up such efforts will be critical as the hazard landscape becomes more complex.

Looking ahead: policy implications and the path forward

The Systemiq report offers a sobering assessment of a rapidly changing Himalayan environment and its far‑reaching consequences for India. The acceleration of glacier melt, the expansion of unstable glacial lakes, and the destabilisation of permafrost together create a cascade of risks that threaten both human safety and economic stability. Yet the report also identifies actionable levers—most notably the reduction of black‑carbon emissions and the expansion of glacier monitoring—that could mitigate some of the most immediate threats.

For policymakers, the challenge will be to translate these recommendations into coordinated, cross‑sectoral action. Strengthening disaster preparedness, reforming tourism, and investing in shared monitoring infrastructure will require collaboration across ministries, states and neighbouring countries. As the Himalayas approach what Lord Nicholas Stern describes as a “tipping point,” the urgency of such collaboration cannot be overstated. The coming years will test India’s ability to protect its mountain communities, preserve a critical water source, and sustain the economic activities that depend on the Third Pole.
