Creator's Description: Academics and policymakers alike are paying increasing attention to the interactions between Tibetan highland pasture and Tibetan nomad communities. An ongoing debate focuses upon the reasons for pasture degradation and overgrazing. Human population is a significant factor in pasture pressure and solutions may be found in this area. Fredrik Barth's research concerning the dynamics of pasture pressure, economic choice, and demography in South Persia's pasture society will be applied in this paper. This research note suggests that population outflow may partially alleviate pasture pressure. Population outflow is driven by individual economic choices but, as will be shown, education in the Nag chu District lies behind these choices. (2008-12-31)
