A form of pastoralism practiced in climates where arable agriculture is impossible, this extensive agricultural practice involves the seasonal movement of livestock between different grazing areas. The herders rely on animals for sustenance, including milk, meat, and blood. Examples of this type of agriculture can be found in arid and semi-arid regions of Africa, the Middle East, and Central Asia, where environmental conditions restrict crop cultivation.
This practice is highly adaptive to marginal environments, allowing human populations to utilize resources that would otherwise be unproductive. It sustains biodiversity by preventing overgrazing in any single location, and it preserves traditional cultural practices and knowledge related to animal husbandry and resource management. Historically, it has shaped trade routes and interactions between different cultural groups, acting as a key economic activity in challenging geographic areas.
