The demand for power is increasing worldwide but especieally the consumption of energy of Asia is predicted to increase tremendously along with their increasing economy and industry. Of course, such an increasing demand also needs places where the energy can be produced and these are, among others, not surprisingly also the rivers and streams in Himalayan region. However, no question, the future plans of constructing more and more hydropower plants and dams in the unique and mostly untouched environment of the Himalayan mountains will not only bear ecological risks but will also have various social impacts. But these future problems are probably not considered yet at all in their complexity.
A recent article in the british Guardian states that over more than 400 hydropower schemes are planned to be built in the Himalayan region (India, Bhutan, Nepal, Pakistan), 100 in Tibet (China) and 60 or even more in the River Mekong (which also rises in the Himalaya, Tibet and flows through south-east Asia). These values and much more interesting facts can be found here in the original article:
