Analysis of Barriers and Challenges Rangeland Management (Case Study: Rangelands Kermanshah province)
This article examines the history of rangeland management on the El Rito District of the Carson National Forest in northern New Mexico. The area became part of the U.S. Forest Service system in the late nineteenth century, when Mexican land grants in the area were not confirmed by U.S. courts. In the 1940s, the Forest Service implemented a series of grazing restrictions in the district. The art...
Background and objectives: Rangelands, as an important part of natural resources, play an essential role in improving or reducing the economic and social conditions of local communities and rural residents. After the Forest and Rangeland Nationalization Act of 1962, in the laws passed in 1969, the exploitation of rangelands was considered as a rangeland management plan for the first time. In th...
A long standing question in range management concerns the relative importance of the stocking rate versus the length of time during which animals graze a particular rangeland. We address this question by analyzing the problem faced by a private rancher who wishes to minimize the long run expected net unit cost from range operations by choosing either the stocking rate or the length of time duri...
Extreme droughts like the recent 2011–2013 drought impacting the central and western United States present a challenge to sustaining livestock ranching operations and the ecosystem goods and services they produce. Wyoming ranchers manage half of this drought-prone state and are at the forefront of this challenge. We examined Wyoming ranchers’ drought management strategies and how ranch characte...
Background and purpose: Livestock exploitation and grazing is the most important human activity, the choice of which depends on various factors. The importance of how to manage customary rangeland systems in recent decades has made it one of the challenges of rangeland management in the country. Rangelands need principled management and planning for existing resources (water, soil and plants) a...
Rangelands are globally extensive, provide fundamental ecosystem services, and are tightly coupled human-ecological systems. Rangeland sustainability depends largely on the implementation and utilization of various grazing and burning practices optimized to protect against soil erosion and transport. In many cases, however, land management practices lead to increased soil erosion and sediment f...
