Nomadic pastoralism, also known as nomadic herding or pastoral nomadism, is a form of pastoralism in which livestock are herded in order to seek for fresh pastures on which to graze. True nomads follow an irregular pattern of movement, in contrast with transhumance, where seasonal pastures are fixed. However, this distinction is often not observed and the term 'nomad' used for both—and in historical cases the regularity of movements is often unknown in any case. The herded livestock include cattle, water buffalo, yaks, llamas, sheep, goats, reindeer, horses, donkeys or camels, or mixtures of species. Nomadic pastoralism is commonly practiced in regions with little arable land, typically in the developing world, especially in the steppe lands north of the agricultural zone of Eurasia. Pastoralists often trade with sedentary agrarians, exchanging meat for grains; however, they have been known to raid.
Of the estimated 30–40 million nomadic pastoralists worldwide, most are found in central Asia and the Sahel region of North and West Africa, such as Fulani, Tuaregs, and Toubou, with some also in the Middle East, such as traditionally Bedouins, and in other parts of Africa, such as Nigeria and Somalia. Increasing numbers of stock may lead to overgrazing of the area and desertification if lands are not allowed to fully recover between one grazing period and the next. Increased enclosure and fencing of land has reduced the amount of land for this practice. There is substantive uncertainty over the extent to which the various causes for degradation affect grassland. Different causes have been identified which include overgrazing, mining, agricultural reclamation, pests and rodents, soil properties, tectonic activity, and climate change. Simultaneously, it is maintained that some, such as overgrazing and overstocking, may be overstated while others, such as climate change, mining and agricultural reclamation, may be under reported. In this context, there is also uncertainty as to the long-term effect of human behavior on the grassland as compared to non-biotic factors.
Origin and history
Nomadic pastoralism was a result of the Neolithic Revolution and the rise of agriculture. During that revolution, humans began domesticating animals and plants for food and started forming cities. Nomadism generally has existed in symbiosis with such settled cultures trading animal products (meat, hides, wool, cheese and other animal products) for manufactured items not produced by the nomadic herders. Henri Fleisch tentatively suggested the Shepherd Neolithic industry of Lebanon may date to the Epipaleolithic and that it may have been used by one of the first cultures of nomadic shepherds in the Beqaa Valley. Andrew Sherratt demonstrates that "early farming populations used livestock mainly for meat, and that other applications were explored as agriculturalists adapted to new conditions, especially in the semi‐arid zone."
In the past it was asserted that pastoral nomads left no presence archaeologically or were impoverished, but this has now been challenged, and was clearly not so for many ancient Eurasian nomads, who have left very rich kurgan burial sites. Pastoral nomadic sites are identified based on their location outside the zone of agriculture, the absence of grains or grain-processing equipment, limited and characteristic architecture, a predominance of sheep and goat bones, and by ethnographic analogy to modern pastoral nomadic peoples. Juris Zarins has proposed that pastoral nomadism began as a cultural lifestyle in the wake of the 6200 BC climatic crisis when Harifian pottery making hunter-gatherers in the Sinai fused with Pre-Pottery Neolithic B agriculturalists to produce the Munhata culture, a nomadic lifestyle based on animal domestication, developing into the Yarmoukian and thence into a circum-Arabian nomadic pastoral complex, and spreading Proto-Semitic languages. In Bronze Age Central Asia, nomadic populations are associated with the earliest transmissions of millet and wheat grains through the region that eventually became central for the Silk Road. Early Indo-European migrations from the Pontic–Caspian steppe spread Yamnaya Steppe pastoralist ancestry and Indo-European languages across large parts of Eurasia. By the medieval period in Central Asia, nomadic communities exhibited isotopically diverse diets, suggesting a multitude of subsistence strategies.
Nomadic pattern in season
Often traditional nomadic groups settle into a regular seasonal pattern of transhumance. An example of a normal nomadic cycle in the northern hemisphere is:
Spring (early April to the end of June) – transition Summer (end of June to late September) – a higher plateau Autumn (mid-September to end of November) – transition Winter (from December to the end of March) – desert plains. The movements in this example are approximately 180 to 200 km. Camps are established in the same place each year; often, semi-permanent shelters are built in at least one place on this migration route. In sub-regions, such as in Chad, the nomadic pastoralist cycle is as follows:
In the rainy season, the groups live in a village intended for a comfortable stay. The villages are often made of sturdy materials such as clay. Old men and women remain in this village when the other people move the herds in the dry season. In the dry season, the people move their herds to southern villages with a more temporary character. They then move inland, where they stay in tent camps. In Chad, the sturdy villages are called hillé, the less sturdy villages are called dankhout and the tents ferik.
