Abstract: Loss of mobility in rangeland use has emerged as a dominant theory to explain ecosystem degradation in the research area of rangeland ecology. The loss of mobility in rangeland use in China resulted from multiple interacting natural and social factors as well as policy changes. Re-establi-shing mobility in rangeland use is critical to rangeland restoration and sustainable management in China. However, the recovery of rangeland might be difficult through simply reverting to traditional rotational grazing. Alternatively, we explored various state-of-the-art rangeland management techniques, including smart fence, intelligent wearables for livestock, and rapid forage biomass measurement using drones. Such novel rangeland management techniques could be used in different regions with different climate and vegetation in China to re-establish mobility in rangeland utilization. Paired with these advanced techniques, new rotational high-mobility grazing systems could further integrate with other essential measures of grass-livestock husbandry in China, such as balancing of forage production and livestock grazing, supplemental forage of livestock, and replenishment of soil nutrients in rangeland. All these practices would ensure a more sustainable and effective utilization of rangeland in China.
