Soil organic C content, a major source of system stability in agroecosystems, is controlled by many factors that have complex interactions. The purpose of this study was to evaluate the major controls over soil organic carbon content, and to predict regional patterns of carbon in range and cultivated soils. We obtained pedon and climate data for 500 rangeland and 300 cultivated soils in the U.S...

Ecological thresholds describe abrupt changes in ecological properties in time or space. In rangeland management, thresholds reflect changes in vegetation and soils that are expensive or impossible to reverse. The threshold concept has catalyzed important advances in rangeland management thinking, but it has also introduced two classes of drawbacks. First, the ambiguity of the term ‘‘threshold’...

Rangeland monitoring aims to determine whether grazing management strategies meet the goals of sustainable resource utilization. The development requires an understanding manner in which animals utilize available vegetation. In this study, we made use livestock tracking, situ observations and Sentinel-2 imagery make rangeland scale vegetation conditions a semi-arid environment, better understan...

the “Three-River Headwaters” region (TRHR) rangeland ecosystem is extremely sensitive and fragile, and in recent years has undergone continuous degradation. The vast area and severe nature conditions inhibit data acquisition and field experiments, resulting in different understandings about the spatial characteristics and dynamics of rangeland degradation in the region. Therefore, reliable moni...

Contemporary Australian rangeland management is characterised by concurrent processes of a continuing intensification of land management practices and simplification of landscape ecological processes. This dual characteristic is associated with increasing levels of potential conflict between land management practices that promote improved economic performance of rangeland enterprises at the app...

Support for range management interventions by the World Bank and other international development institutions has a somewhat checkered history. In certain respects, this has mirrored theoretical developments and shifts in thinking among rangeland professionals, but the relationship between rangeland science and development policy and practice is far from direct. It is mediated by contextual fac...
