    Background Pastoralists have long inhabited vast areas of western China, including the Tibetan Plateau region. Their traditional land use practices and cultural conservation ethic have helped to protect the natural resource base upon which they depend and the wildlife that co-exist with them in the grassland landscapes.

    Dzud is the Mongolian term for a winter weather disaster in which deep snow, severe cold, or other conditions render forage unavailable or inaccessible and lead to high livestock mortality. Dzud is a regular occurrence in Mongolia, and plays an important role in regulating livestock populations. However, dzud, especially when combined with other environmental or socio-economic stresses and changes, can have a significant impact on household well-being as well as local and national economies.

    Sedge dominated peatlands do not rehabilitate well after being drained for rangelands and specific approaches are required in order to restore these sites. Restoration by blocking drainage canals aims to recover peatland functions, principally by raising the water table. Field surveys in Ruoergai, China identified the status of peatland degradation and satellite image analysis concluded that most of Ruoergai's peatlands are degraded mainly due to drainage and overgrazing.

    The Inner Mongolian grassland steppe is the most important grazing land in China in terms of cow milk, mutton, and cashmere production. However, intensive livestock grazing has severely degraded the steppe grassland. A sophisticated grazing management is therefore essential for an economically viable use of the grassland without amplifying its desertification.

    Investigating traditional ecological knowledge (TEK) by the scientific approach is a useful way to develop sustainable rangeland management. Numerous trials have been done on plant species compositions and biomass, but little testing has been done on the TEK of plant productivity and nutrient values, which are important for proper rangeland management. In this study, we tested the TEK of pastoralists living in Bulgan, northern Mongolia, regarding plant productivity and nutrient values. We examined biomass, growth form, plant productivity, and crude protein amounts along grazing gradients.

    Overgrazing is a primary agent to cause and aggravate desertification in the Horqin Sandy Grassland of northern China that has reduced the capacity of carbon (C) and nitrogen (N) storage in the region. Grazing exclosure practice is recommended to control the desertification by vegetation restoration. How the restoration improves the C and N storage needs to be answered to the policy makers for their future land use planning and decisions.
