Deserts are usually found on the western margin of the continent between 20° and 30° N and S latitudes.

The annual rainfall is less than 25 cm.

Due to lack of rainfall and arid conditions, these areas do not possess any vegetation but have a special vegetation type called Xerophytes.

The soil is sandy and saline, the deserts are agriculturally not fit. Drought-resistant thorny shrubs and bushes, palms are found in deserts.

Tribal people gather food and practice hunting. They move frequently in search of pastures and move their temporary settlements.
