SSC MTS EXAM

Detailed explanation-1: -Pastoral nomads, who depend on domesticated livestock, migrate in an established territory to find pasturage for their animals. Most nomadic groups have focal sites that they occupy for considerable periods of the year.

Detailed explanation-2: -Some communities did a bit of farming, domesticated some animals, but remained largely nomadic. Others farmed some of the year and relied on trade at other times. Some communities who had previously farmed, like those occupying the Sahara region in Africa, became nomadic pastoralists as the region became more arid.

Detailed explanation-3: -Pastoralists can raise a range of different animals, although most often they raise herd animals such as cows, goats, sheep, and pigs. In some parts of South America, alpaca and llama have been domesticated for centuries to act as beasts of burden, much like camels, horses, and donkeys are used in Asia and Africa .
