Ladakh is a high altitude desert as the Himalayas create a rain shadow, generally denying entry to monsoon clouds. The main source of water is the winter snowfall on the mountains. Recent flooding in the region (e.g., the 2010 floods) has been attributed to abnormal rain patterns and retreating glaciers, both of which have been found to be linked to global climate change. The Leh Nutrition Project, headed by Chewang Norphel, also known as the "Glacier Man", creates artificial glaciers as one solution for retreating glaciers.
