Pastoralists migrate with their animals in some of the most remote and marginal environments on the planet. Globally, mobile pastoralists number about 200 million households and use about 25% of the Earth's landmass . Many pastoralists operate in non- equilibrial environments that are unstable, fluctuating and generally uncertain, and are driven more by climatic variation than livestock numbers and grazing pressure . Examples of such systems are grazing areas in the dry tropics  and rangelands in the Arctic .
