INTRODUCTION Analyzing trends of land use systems and the changes occurred overtime is an effective way of assessing the impacts of land use/land cover (LULC) changes on ecosystem function. It provides important insights for understanding the spatial patterns of land use processes. The rangelands of southern Ethiopia are adversely affected by increased human population pressure, encroachment of...

Humans have exerted large-scale changes on the terrestrial biosphere, primarily through agriculture; however, the impacts of such changes on the hydrologic cycle are poorly understood. The purpose of this study was to test the hypothesis that the conversion of natural rangeland ecosystems to agricultural ecosystems impacts the subsurface portion of the hydrologic cycle by changing groundwater r...

assignment of additional exploitation of rangelands including ecotourism to the natives in addition to compensation for residents is thought to prevent further destruction of the pastures. in doing so, the local communities are financially supported and so their participation rate will be higher in protecting and restoring of rangelands. lasem watershed is one of iran's rangelands with gre...

Under the harsh environmental conditions present in severely overgrazed, semiarid rangelands, facilitator plants offer a promising tool for ecological restoration. This study investigated facilitative effects of Aloe secundiflora—a native drought-tolerant, unpalatable, thorny shrub—on grass establishment in degraded rangelands in Kenya. We planted native perennial grass seeds adjacent to three ...

Land desertification is one of the most serious environmental and social-economic problems in the North China. The processes of desertification mainly have being controlled by the interaction of human activities and fragile eco-environment, that means the pattern and intension of landuse are major factors for development or reverse of desertification. Because of the increasing pressure of popul...

Maintaining or enhancing the productive capacity and resilience of rangeland ecosystems is critical for the continued support of people who depend on them for their livelihoods, especially in the face of climatic change. This is also necessary for the continued delivery of ecosystem services derived from rangelands for the broader benefit of societies around the world. Multi-paddock grazing man...

effect of two fattening systems were studied on feedlot performance and carcass characteristics of using of 66 fars native male kids in different ages. six kids were slaughtered at the first day of experiment and sixty kids were divided into two groups. the first group were kept in feedlot in individual pens and the second group grazed on rangeland, and after 3 months, were kept in feedlot in i...

Abstract Russian thistle, also known as tumbleweed ( Salsola spp.), is a problematic invasive plant found on natural and working landscapes. On California rangeland, we tested the singular interactive treatments of grazing, herbicide, seeding to determine how these approaches might influence cover across 5-yr experiment. Total declined by 3% annually during study. A single spring treatment chlo...
