A project in Ladakh, India, creates “ice stupas”, a form of artificial glacier, to complement intermittent water flow from retreating natural glaciers. Water from streams is sprayed from vertical pipes during the winter, freezing into pointed mounds, which melt slowly throughout the year, irrigating crops in the summer.
