Procedures for estimation of the livestock ecological footprint in US drylands

摘要：

Introduction The ecological condition and trend of the United States3,902,000 km-２ of Drylands and the extent to which human management actions contribute to degradation are unknown at the national spatial scale (Washington-Allen et al.2006).Our research seeks to develop procedures for determining the impact or ecological footprint of livestock grazing on the productive capacity of Drylands at the national spatial scale.
