Explain why nomadic tribes need to move from one place to another. What are the advantages to the environment of this continuous movement?

There were many need of nomadic tribes to move from one

place to another:

→ The nomadic tribes had no regular fields of their own from

where they could get fodder for their cattle.

→ They lived with their herd in the low hills of Himalayas from

September to April because; the huge mountains or high

altitudes were covered with snow during this period. In these

areas the dry scrub forests provided pastures for their herds

during this period.

→ With the onset of summer, as the snow melted and the hill

sides began to be covered with lush green with a variety of new

grasses, the pastoralists started their northward march for their

summer grazing grounds.

→ Again with the onset of winter when the mountains began to

be covered with snow and there were dearth of nutritious

forage, these pastoralists on the move again, this time on their downward journey.

The movement of the nomadic pastoralists from the downward

to the upward areas and vice-versa allowed sufficient time for

natural restoration of vegetation grounds. Their continuous

shifting provided sufficient forage to the different animals both

at the high mountains and the lower hills. They also helped in

maintaining the quality of the pastures.
