Floods down in the south, and yet in the north and west:
 “There is 320,000 square km of land threatened by desertification in China, a State Forestry Administration (SFA) official said here Sunday.”
But desertification stands to have very serious effects beyond the areas that are turning to sand:
“Recent research has found ecological degradation at the headwaters of the Yellow River and Yangtze River, China’s two biggest rivers, and signs of desertification have emerged in some parts of the river source area, the official said.”
Not just those two, either. Look at a map: Most of the major rivers of China, South Asia, and Southeast Asia begin on the Qinghai-Tibet plateau.
