====== Task 2 ====== Chewing Norphel : Climate Hero who is well known as Ice Man and White Knight

About Ladakh : With only 5 cm of rain, Ladakh, place full of mountains is a high altitude desert. Geographically, Ladakh is rain shadowed by Huge of mass of Himalayas which obstruct the entry of Indian monsoons to this high altitude plateau. People in Ladakh since ages were depended on glaciers for cultivation of crops. With the incidence of global warming, most of the glaciers in the area vanished in last 15 years. With brief summer, retreated glaciers causing lack of melt water in the region of Ladakh, people started to face problems of water for cultivation of annual crops.

Chewang Norphel, a retired civil engineer, found solution for people in this region with concept of artificial glaciers for water conservation. . He built simple cheap and huge dams in the area to collect the water from melting ice. Seeing people migrating to different cities and suffering with water problems, Chewang Norphel, tried so many different ways to conserve water in the area. After so many different concepts, he decided to built simple dams in the lower elevation valleys to make artificial glaciers which would increase the ground wanter level and also can be used by people for cultivation in the proper season. By building 12 dams for artificial glaciers, he is the Ice Man, White Knight and a true climate hero.

Chewang Norphels Message: Save every drop of water and act before it is too late.
