“…Alpine meadows, because of their sod-forming habit and their role in soil protection [23,24] are particularly important in the headwater regions on the QTP. The largest and most important of these is the so-called Three Rivers Regions (Sanjiangyuan).…”

“…To protect the head waters of many important rivers (including five that are international rivers, there are plans to remove more than 200,000 herders and their livestock to new resettlement areas outside the Sanjiangyuan region. On one hand, there is the laudable attempt to conserve biodiversity and habitat [12,24] that is currently under threat from too many people and too many livestock competing for water and forage. The success or otherwise of the resettlement is the subject of considerable debate [25][26][27][28][29][30].…”

“…Restrictions on herder mobility cause concentration of livestock in critical 'refuge areas'. The changes in the length of the growing season (earlier 'green-up' and later senescence in the autumn) encourage extension of the grazing on 'summer pastures' to the detriment of native ungulates (and other fauna) that overwinter there [13,24,25]. See discussion on phenology in Section 4 below.…”

“…In particular it is critical to investigate the rationale underlying 'traditional' grazing practices and ascertain the role of practices grazing (both good and bad) in grassland degradation. The common assumption that overgrazing is a key factor is questioned by some authors [12,24,25,33] yet this influences current policies such as sedentarization and new fencing regimes that appear to produce mixed ecological outcomes [36,37].…”

“…Until relatively recently, the long-term ecological implications of privatizing grassland and reducing spatial movement (including transhumance) had received little analysis despite early work by [24,36,38]. Arguments are mounting that flexible grazing practices are essential if there is to be sustainable grassland management [24,25,27,31].…”

Alpine grasslands are a common feature on the extensive (2.6 million km2) Qinghai–Tibet plateau in western and southwestern China. These grasslands are characterized by their ability to thrive at high altitudes and in areas with short growing seasons and low humidity. Alpine steppe and alpine meadow are the principal plant Formations supporting a rich species mix of grass and forb species, many of them endemic. Alpine grasslands are the mainstay of pastoralism where yaks and hardy Tibetan sheep and Bactrian camels are the favored livestock in the cold arid region. It is not only their importance to local semi nomadic herders, but their role as headwaters of nine major rivers that provide water to more than one billion people in China and in neighboring countries in south and south-east Asia and beyond. Grasslands in this region were heavily utilized in recent decades and are facing accelerated land degradation. Government and herder responses, although quite different, are being implemented as climate change and the transition to the market economy proceeds apace. Problems and prospects for alpine grasslands and the management regimes being imposed (including sedentarization, resettlement and global warming are briefly discussed.

With the changing trend of global temperature increase, the occurrence of drought events can no longer be ignored. An investigation of the spatiotemporal evolution characteristics of meteorological droughts and their responses to climatic variables can elucidate the mechanisms of the water cycle evolution in changing environments. In the present study, the standardized precipitation evapotranspiration index was used to characterize meteorological drought in the North China Plain (NCP) from 1970 to 2020. The spatiotemporal patterns of meteorological drought were analysed, and the contributions of climatic factors on annual and seasonal time scale drought evolution were determined. The results revealed that meteorological drought showed a decreasing trend (−0.07/10a) in the NCP from 1970 to 2020 and the most severe meteorological drought occurred in winter, with 56.56% of the region experiencing an increased drought trend in this season. Significant trends were identified for mean temperature (Tmean), temperature difference, and wind speed in the drought trend evolution. Precipitation (P) and Tmean were the primary controlling factors of the drought evolution. The strongest effect on drought change were exerted by P in spring (contribution [Con]: 1.57%), summer (Con: 1.79%) and autumn (Con: 2.43%), and the negative contribution of Tmean in winter (Con: −3.64%) was greater than the positive contribution of P (Con: 2.69%). The contribution of climatic variables to drought were increased by regional altitude difference. The results reveal a novel explanatory mechanism of climate change's effects on drought.
