Abstract:The headwaters region of the Yangtze, Yellow, and Lancangjiang rivers is located on the Tibetan plateau with total land area is 366400 km2. However, there are evidences for expanding grassland degradation and soil erosion in the region caused by over grazing and unfavorable climate changes. Integrated management is the most effective approach for regenerating the productivity of degraded pasturelands. Fencing, reseeding, scarification are the common methods for revival of vegetative cover for degraded pastureland. Harnessing of ecological principles and biological processes, the grazing pattern, grazing density, sheep and yaks feedlot fattening, sustainable livestock production system are approached according to serial pilot studies in the region.
