In the arid and semi-arid regions of Northeast Asia, grassland degradation has become a major environmental and economic problem, so sustainable utilization of resources is crucial in terms of not only supporting the local and animal production but also thinking about the global environment. Especially in Mongolia and North China, grassland degradation has mainly been induced by artificial fact...

water is an unconventional economic good because it is:-a 'fugitive' and re-usable good,-a public good and often under common property regime,-a stochastically supplied and distributed resource,-subject to economies of scale in provision,-essential to plant and animal life, with no substitute,-associated with many non-market environmental qualities and values. In the context of arid and semi-ar...
