Sonam Wangchuk is an engineer who has come up with an innovative way to provide fresh water to villages in Ladakh, one of the high-altitude deserts in the world located in the Himalayas. 

Wangchuk sources water from streams and uses it to create artificial glaciers, which store fresh water until it’s needed in springtime.
