Quick Answer

The Full Story
Dry climates, including deserts and semi-arid regions, cover a very large portion of Earth’s land surface. Estimates commonly place drylands at around 30 to 40 percent of global land, making them one of the largest climate groupings on the planet. These regions are defined more by a lack of precipitation than by temperature alone. Their extent is important for agriculture, water management, and biodiversity conservation.
