Tropical Deserts

Vegetation that grows in a natural region without any human interference is known as natural vegetation. A natural region is a basic geographic unit that is characterized by its common natural features of geography, geology, and climate. Climate is a basic factor upon which natural regions are divided. It influences flora, fauna, and vegetation in the region. Climate is classified on factors such as temperature, winds, pressure, humidity, rainfall, landforms, types of soil, natural vegetation, and wildlife. Based on these factors, the world is divided into various natural regions such as the equatorial region, tropical grasslands, tropical deserts, tropical monsoon type of climate, the Mediterranean region, China type of climate, temperate grasslands, temperate deserts, and taiga and tundra regions.


Tropical Deserts


Natural Vegetation and Animals found in Tropical Deserts

  • Because of scanty rainfall, thorny scrubs like cactus and prickly pear are found in the region.
  • Mostly xerophytic plants grow in the region. Plants which adapt themselves to the dry climate are known as xerophytes.
  • Trees of date palm are found near the oasis or near water courses.
  • Burrowing animals (animals which dig holes in the ground to escape heat) such as lizards, squirrels, snakes, rats, foxes and mice are found.

Climate of Tropical Deserts

  • Deserts have hot summers and cool winters.
  • It has a high daily range of temperature.

Human Adaptation

  • Mostly nomadic hunters and food gatherers inhabit the tropical deserts. Some primitive tribes inhabiting the deserts are the Bushmen of Kalahari, the Bedouins in the Sahara, and the Bindibu in Australia.
  • Cultivation in small patches can be carried out only in an oasis or along the bank of a river. The Egyptians grow barley, cotton, wheat, sugar, fruits, and vegetables along River Nil.
