Concept information
Preferred term
arid zone
Definition
- [Henderson's] regions extending from latitudes 15° to 30° in both hemispheres in which rainfall is very low and either evaporates in the high daytime temperatures or drains away rapidly so that it is unavailable to vegetation. This zone contains most of the world’s deserts. Parts of the zone support vegetation and some cultivation but are subject to overgrazing and overcultivation in times of drought, which can lead to desertification.
