Environmentalists and pastoralists have accepted the fact that pastoral nomadism is a form of life which is best suited for hilly and dry regions in the world. The grazing activities of their cattle also do not affect ecological balance. It is because in the hilly regions, the regular movements of pastoral community allow the pasturelands to replenish.
