The grassbank concept: potential applications in China ?
Introduction and methods In the disequilibrium environments of arid rangelands, unusual shortages of forage within years and between years can be expected but seldom predicted.While conservative stocking can help to protect rangelands and pastoralists from much of the variability, at times there will be forage shortages despite a low stocking rate.Traditional mobility allowed the movement of stock over long distances to evade forage‐short conditions.However, as rangeland tenure is fragmented and lands are fenced, new strategies are needed (Roe and Huntsinger 1998).In the United States, a group of pastoralists in the arid southwest known as the Malpai Borderlands Group developed what they term the.grassbank concept to cope with drought and support range improvement and conservation, and it has been applied with mixed success in various parts of the west (White,2007 ; Gripne, 2005).This paper considers the potential application of the grassbank strategy in China, using archival sources and policy analysis.
