Wangchuk’s design builds on the experimental work of fellow Ladakhi engineer Chewang Norphel, who created flat artificial glaciers. Wangchuk realized, however, that a workable structure must have a minimal surface area to provide protection from the sun, especially at lower altitudes. Thanks to this design, ice stupas melt at a slower rate than flat ice. The 2015 prototype, the result of a crowdfunding campaign that paid for a 2.3 km pipeline to direct glacial streams down to the village desert, lasted until early July, supplying 1.5 million litres of meltwater to 5,000 saplings planted by locals.
With his Rolex Award funds he intends to create up to 20 ice stupas, each 30 metres high, and initiate a substantial tree-planting programme on the desert near their school once the new water supply system is established.
Wangchuk believes that education and care for the environment go hand in hand. In addition to his work with young people at SECMOL, the Students’ Educational and Cultural Movement of Ladakh, through its Alternative School he has started work on establishing an alternative university in the same area. His objective is to engage young people from the Himalayas and beyond in eco-solutions for mountain areas.
