Combating Desertification in an Extremely Arid Area of Central Asia
Extremely Arid Desert, an area with an annual precipitation of lower than 100mm and a moisture index of less than 0.05, is classified as non- desertified area. The extremely arid desert is usually regarded as an area where no further desertification would occur. But the Tarim Basin and the western part of the Hexi Corridor in the extremely arid area of China in Central Asia, with more than 3 million people living in the azonal oases and riparian areas of the desert that are supplied by water from rivers and irrigating canals or by groundwater, is seriously threatened and affected by drought, salinization, wind erosion, sand drift and moving sand dune. This presentation deals with the driest lower reach of the Tarim River and Lop Nor area in the Central Asia, analyses the causes and mechanism of desertification, and puts forward proposals for combating desertification in the area.
