Nomadism

is common in arid areas

Hunting is the reason for nomadism (not sure if that is legit). Nomads move from one place to another to follow herds of game aniamls, such as buffalo. Gathering is just a way for them to collect food they cannot attain from hunting.

Pastoral nomadism is commonly found in arid and semi-arid climate regions where agriculture is difficult due to limited rainfall and vegetation. These areas are often characterized by grasslands or deserts that are suitable for grazing livestock.
