Final answer:
Transhumance is a form of pastoralism where groups move their herds between two households seasonally to access fresh pastures and is related to moving herds in response to seasonal changes.
Step-by-step explanation:
Transhumance is a technique practiced by many pastoralist groups that combines a settled lifestyle with routine movement. This practice involves the seasonal migration between a family's two households, typically located in different geographical areas, to adapt to seasonal changes in climate and vegetation growth. During these migrations, which can take days or weeks, pastoralists move their herds of domestic animals, such as cattle, sheep, goats, camelids (llamas and alpacas), and yaks, from one residence to another to access fresh pastures and meet the needs of their animals.
In some cases, societies that practice transhumance may move between two permanent settlements following an annual cycle. For example, Bedouin herders move their herds between summer and winter settlements and may engage in small-scale farming alongside herding. Transhumant pastoralism and its relationship to moving herds and seasonal changes are critical for understanding the strategies used by pastoral societies to sustain themselves and their animals, often in symbiosis with agricultural societies for trade and other commodities.
