Hardin’s Tragedy of the Commons has often been cited as the rationale for the privatization of pastures throughout the world, yet rangeland degradation is still widespread. A significant body of ecological research has demonstrated negative impacts from limiting herd movement through fencing. The privatization of pastures has often followed heterogeneous patterns. We use a natural experiment in common grazing areas on the eastern Qinghai-Tibetan Plateau where land use was privatized beginning in 1999 following different land use division patterns. We measure the relationship between land use privatization paths and grassland quality using satellite data from 1989 to 2011 in five different villages, and compare how well herder environmental perceptions match satellite data. We find that rangeland degradation has significantly increased following privatization of land use, and that grassland in small individually managed fenced plots is deteriorating more significantly than in larger fenced areas with group herding. We further find that herders’ had accurate perceptions of the state of their pastures that closely match remotely sensed data.

将当地知识和环境变化与牧场权属政策变化相匹配

哈丁的公地悲剧经常被引用为全世界牧场私有化的理由,但牧场退化仍然普遍存在。大量生态研究表明,通过围栏限制畜群活动会产生负面影响。牧场私有化通常遵循不同的模式。我们在青藏高原东部的普通放牧区进行了一项自然试验,该地区的土地利用按照不同的土地利用划分模式于 1999 年开始私有化。我们使用 1989 年至 2011 年五个不同村庄的卫星数据衡量土地利用私有化路径与草地质量之间的关系,并比较牧民环境感知与卫星数据的匹配程度。我们发现,在土地使用私有化后,牧场退化显着增加,并且与群体放牧的较大围栏区域相比,小型单独管理的围栏地块中的草地退化更为显着。我们进一步发现,牧民对其牧场状况的准确感知与遥感数据密切匹配。
