Reports from Leh indicate that precipitation has dropped during the past
quarter-century as temperatures have risen, a possible consequence of climate
change. But the real threat is to the heart of the greater Himalayas and the
vast Tibetan Plateau, where more than 40,000 sq. mi. of glaciers hold water in
the largest collection of land ice outside the polar regions. "These glaciers
are central to the region," says Hasnain, looking over Khardung La. "If we don't
have snow and ice here, people will die." It's a population that is stressed for water, even if the ice doesn't disappear.
According to the International Water Management Institute (IWMI), most of South
Asia is already in a state of water scarcity, as is much of China. At the same
time, the population in this part of the world is set to expand, even as
economic growth increases competition for water used in agriculture and
industry. |
