Nomadic conflict
Nomadic conflict, also called farmer–herder conflict, is a type of environmental conflict where farming and herding communities overlap and has been used to refer to fighting among herding communities or fighting between herding and farming communities. This is sometimes referred to as conflict involving "pastoralists" or "nomadic" people and "agriculturalists" or "settled" people. The conflicts usually arise from destruction of crops by livestock and is exacerbated during times when water and lands to graze are scarce.
Background
There are several hundred million pastoralists worldwide and Africa contains about 268 million pastoralists, over a quarter of its population, who live on about 43 percent of the continent's land mass.Commercial displacement
Displacement of local communities to make way for commercial farms or mining activities has put pressure on grazing areas, exacerbating conflict.Climate change and land degradation
in the Sahel, where much of the present-day conflicts between herders and farmers takes place, is expanding southward by about 1400 square miles a year. Climate change has apparently exacerbated land degradation, which leads to more competition over grazing areas.History
Malti Malik summarises relationships and inter-dependencies between sheep-herders and sedentary farmers in Mari, a city-state on the Euphrates which flourished between 2900 and 1759 BCE. The "nomadic groups included the Akkadians, Amorites, Assyrians and Aramaeans. Some of them gained much power and succeeded in establishing their own rule. For example, the kings of Mari were Amorites." Interactions included trade and employment as well as "robbing and plundering".Similarly, in the 13th century CE nomadic Mongols subjugated many of the agriculture-based states of Eurasia and founded the Mongol Empire.
