Pastoralism is the practice of raising livestock as a primary or secondary way of making a living. It spans roughly 25% of Earth’s land area, mostly across the drylands of Africa and the Arabian Peninsula, the highlands of Asia, and parts of Latin America. Far from a relic of the past, pastoralism remains a living economic system that supports hundreds of millions of people and shapes vast stretches of the planet’s ecosystems.
How Pastoralism Works
At its core, pastoralism revolves around managing herds of animals, most commonly cattle, camels, sheep, and goats, and moving them to where food and water are available. What separates it from conventional ranching or farming is mobility. Pastoralists follow seasonal patterns of rainfall and vegetation rather than confining animals to a fixed plot of land.
The practice exists on a spectrum. At one end, agropastoralists combine crop cultivation with herding, growing grain or vegetables while also keeping animals. In the middle, transhumant pastoralists maintain a permanent home base but move their herds seasonally between lowland and highland pastures. At the far end, fully nomadic pastoralists relocate their entire households to follow grazing resources, often across semi-arid landscapes where rain is unpredictable and vegetation grows in scattered patches.
What Pastoralists Eat
Livestock aren’t just an economic asset for pastoral communities. They’re the primary food source. In eastern Africa today, milk and milk products from cattle, camels, sheep, and goats provide between 60% and 90% of total calories. Meat supplements the diet, along with seasonally available wild plants and, increasingly, introduced staples like maize and beans. This heavy reliance on animal products is not a dietary preference so much as an ecological reality: in arid and semi-arid regions, the land simply cannot support reliable crop agriculture, but it can sustain grazing animals that convert sparse grasses into nutrient-dense food.
How Animals Survive Harsh Climates
The livestock pastoralists depend on have evolved or been selectively bred over centuries to handle extreme heat and limited water. Cattle and sheep regulate body temperature through sweating, with sweat glands ramping up during the dry season to dissipate heat through evaporation. When temperatures climb, animals also increase their breathing rate, a form of panting that works much the same way. Camels, the iconic pastoralist animal in the most arid regions, go further: they can tolerate wide swings in body temperature and lose enormous amounts of body water before becoming distressed, something cattle cannot do.
These biological adaptations matter because they determine which animals thrive in which environments. Pastoralists in the Sahel keep zebu cattle with loose skin and large sweat glands. Communities in the Gobi or Tibetan Plateau rely on yaks adapted to cold and altitude. The match between animal and landscape is the foundation of the entire system.
Pastoralism and the Land
A common misconception is that grazing degrades land. The relationship is more nuanced. Research from the U.S. Great Plains found that grazing can increase soil carbon storage during wet periods, as livestock stimulate plant regrowth and nutrient cycling. During droughts, the effect reverses, and grazing can reduce soil carbon. Over decades, the difference between grazed and ungrazed land in semi-arid grasslands largely washes out, with soil moisture and total plant productivity playing a bigger role than whether animals are present.
What this means in practice is that well-managed, mobile grazing, the kind pastoralists have practiced for millennia, tends to work with the ecosystem rather than against it. By moving herds before any single area is overgrazed, pastoralists allow vegetation to recover. Problems arise when movement is restricted, forcing too many animals onto too little land for too long.
The Land Rights Problem
The single biggest threat to pastoralism in most regions is not drought or disease but land tenure. Pastoralists typically manage resources communally: a clan or group shares access to a wide territory of grazing land, water points, and migration corridors. This system works well ecologically but clashes with modern legal frameworks built around private ownership and fixed boundaries.
When governments formalize land rights, they often draw lines around administrative units that don’t match how pastoralists actually use the land. Privatization can block migration routes entirely, trapping herds in areas too small to sustain them. Some communities have pushed for communal land titles at larger scales, which preserve the flexibility of movement but come with their own challenges around enforcement and security. There is no clean solution. Pastoralists in East Africa, for example, often prefer traditional territory systems (like the Dheeda among the Borana people) that allow maximum mobility, even though these are harder to defend legally.
Climate Change and Shifting Pastures
Rising temperatures and declining rainfall are compressing the resources pastoralists depend on. As droughts become more frequent and severe, palatable grasses produce less forage, and water sources dry up earlier in the season. This forces changes to the grazing calendar, the carefully timed cycle of when herds enter and leave particular pastures. Communities that once migrated on predictable schedules now face uncertainty about when and where grass will grow.
Desertification compounds the problem. As rangeland degrades, the patches of usable pasture shrink, concentrating herders and livestock into smaller areas. This increases competition and, in many regions, conflict between pastoral groups or between pastoralists and settled farmers. The communities that have the longest history of managing variable climates are, paradoxically, the ones being squeezed hardest by climate shifts that exceed historical norms.
Technology on the Range
Digital tools are beginning to change how pastoralists make decisions. In East Africa, an app that combines satellite imagery, indigenous knowledge, and community reports helps herders locate green pasture and surface water in near real-time. Users report saving an average of nearly three days per scouting trip, time previously spent walking long distances to check conditions in person. “We can now figure out where to migrate next,” one Kenyan pastoralist told Nature. “We know precisely where fresh green pasture and water is to be found without coming into conflict with other herders.”
Mobile banking and digital marketplaces are also reaching pastoral areas, giving herders access to fair livestock prices and financial services that were previously unavailable in remote regions. These tools are not evenly distributed, though. Women in pastoral communities are far less likely to have access to mobile phones or reliable internet, limiting their ability to benefit from the same information on weather, markets, and best practices.
Global Recognition
The United Nations declared 2026 the International Year of Rangelands and Pastoralists, a signal that the global community is paying closer attention. The initiative calls for securing pastoralists’ access to land and natural resources, supporting herd mobility, strengthening animal health services, and building fairer market systems. It also emphasizes inclusive dialogue, particularly ensuring that pastoral communities themselves shape the policies that affect their lives rather than having solutions imposed from outside.
The underlying message is that pastoralism is not a problem to be solved or a primitive stage to be modernized away from. It is a sophisticated, adaptive system for producing food and managing landscapes in environments where other approaches fail. Roughly a quarter of the planet’s land surface functions under some form of pastoral management, and the people who maintain these systems hold ecological knowledge that no satellite or policy document can replace.
