Should the Himalaya Be Built On At All?

The Himalaya Keeps Warning Us. We Keep Building Anyway.

Nepal's glacial flood killed hundreds and wiped out over a tenth of the country's hydropower capacity in minutes. It is tempting to read this as an unforeseeable act of nature. It was not. Two years before the 2023 South Lhonak lake outburst destroyed Sikkim's 1200 MW Teesta-III dam, scientists had already flagged the lake as dangerously unstable.

Eight years before the 2013 Kedarnath floods, a similar catastrophe was recognisable in the region's geology. The Himalaya does not fail to warn us. We fail to act on the warning.

The Genuine Case for Continued Development

It would be dishonest to pretend hydropower and tourism infrastructure in the mountains serve no purpose. These river valleys have some of the world's steepest hydropower potential, critical to India's clean-energy transition and to Nepal's national income.

Pilgrimage towns like Kedarnath support tens of thousands of daily livelihoods dependent on religious tourism. Halting all construction would strip mountain economies of income with no comparable replacement on offer, punishing precisely the communities least responsible for the risk and least able to absorb the loss.

The Genuine Case for a Moratorium But the

counter-argument carries equal weight. Every major precedent - Chorabari in 2013, Chamoli in 2021, South Lhonak in 2023 - shows infrastructure built in the direct path of known or plausible glacial hazards, destroyed with a death toll attached.

A "no construction within 500 metres of riverbanks" rule proposed after Kedarnath was never enforced; hotels have since mushroomed back onto the same riverbanks. When warnings are documented and construction proceeds regardless, continued expansion stops being a bet on probability and becomes a bet against evidence already in hand.

Where This Actually Lands

Neither position survives contact with the other's strongest evidence intact - which is exactly why the debate keeps resurfacing instead of resolving. The way through is not choosing between unchecked development and a blanket halt, but making enforcement, not construction itself, the target.

A hazard-mapped no-construction buffer around glacial lakes and steep valley floors, legally binding rather than advisory, would have stopped both Teesta-III and much of Kedarnath's riverside construction without banning hydropower or pilgrimage elsewhere.

Alongside it, mandatory cross-border data-sharing between India, Nepal and China on glacial lake monitoring - currently inconsistent and politically contingent - would give downstream communities actual warning time, something Nepal's own early-warning system for the Bhotekoshi could not provide against a sudden debris surge.

The Real Failure Is Enforcement, Not Ambition This is not a

call to stop building in the mountains. It is a recognition that India, Nepal and China have consistently possessed the scientific knowledge to prevent these specific disasters and consistently declined to act on it before the fact. The next glacial lake flagged as unstable should trigger an enforceable construction freeze in its path, not another after-the-fact accounting of what was destroyed.
