Artificial glaciers help farmers in India

To offset the disruptive irrigation effects brought on by global warming, the small village of Stakmo, India has been developing a method for creating its own artificial glaciers. The process involves diverting unused autumn and winter runoffs into specially constructed rock reservoirs that hold the water. As the weather grows colder, the collected water freezes, maintaining the supply of water until spring when it begins to melt. This innovative technique provides water to farmers during the planting season when natural glaciers still haven't thawed due to their higher elevations.
