Applicability of criteria and indicators for sustainable grassland management to rangelands of Patagonia(Argentina)

摘要：

Key points:One hundred years of pastoral use of Patagonia.s rangelands have resulted in severe land degradation. Widespread application of range survey methods to determine grazing capacity of commercial ranches did not begin until the late 1980s. Public awareness about desertification problems and efforts of the science community led to the Key points:passing of an important congressional act in 2002 which has created the conditions for the implementation of a region‐wide rangeland monitoring system (MARAS). Although most of the criteria and indicators for sustainable rangeland management proposed by the Sustainable Rangelands Roundtable are relevant to conditions in Patagonia (Argentina), less than half the indicators are applicable due to the relative paucity of data and validated models. Current monitoring frameworks allow broad spatial scale assessments but are somewhat lacking in fine‐scale evaluation of indicators.
