It is early June and the harsh sun beats down in Phyang village in the Ladakh Himalayas of northern India. Yet, two giant artificial glaciers, created in the form of ice stupas by environmental engineer Sonam Wangchuk, still stand tall through the sunny weather. This provides enough water for the village to irrigate their farmland in spring, before the mountain glaciers start melting from late July.
Close to the ice stupas you can hear the gentle dripping of melt water, which flows down through a large pipe connected to a reservoir. The water is then taken to irrigate a large plantation area in the village – an oasis in the dry desert landscape of the Himalayan plateau.
Melting glaciers, water shortages
In the dry desert of Ladakh, farmers depend on water from melting snow and glaciers. But in recent years there has been very little or no snowfall during the winter. Wangchuk’s invention is seeking to resolve this problem by making water available to farms in spring through artificial glaciers within villages.
Wangchuk shot into prominence by devising a way to create small artificial glaciers, or ice stupas, by freezing stream water during the winter in the form of ice towers up to 50 metres high. His idea, he says, was inspired by the artificial glaciers created by his fellow Ladakhi engineer, 83-year-old Chewang Norphel. Norphel created at heights of 4,000 metres and above, which were very hard for villagers to reach. But Wangchuk found a way of storing water close to the villages. His innovation has not only earned him accolades within India, but globally as well. He was one of five people worldwide to win the Rolex Award in November 2016.
