A modern example of desert farming is the Imperial Valley in California, which has high temperatures and average rainfall of just 3 in (76 mm) per year. [121] The economy is heavily based on agriculture and the land is irrigated through a network of canals and pipelines sourced entirely from the Colorado River via the All-American Canal .
There are two variations of a desert climate according to the Köppen climate classification: a hot desert climate (BWh), and a cold desert climate (BWk). To delineate "hot desert climates" from "cold desert climates", a mean annual temperature of 18 °C (64.4 °F) is used as an isotherm so that a location with a BW type climate with the ...
Low levels of humidity in hot deserts contribute to high daytime temperatures, and extensive night time heat loss. The average annual temperature in hot deserts is approximately 20 to 25 °C, however, extreme weather conditions can lead to temperatures ranging from -18 to 49 °C. Rainfall generally occurs, followed by long periods of dryness.
The average annual temperature in the desert varies from about 13 to 22 °C (55 to 72 °F), depending on elevation and latitude. The mean annual precipitation for the Chihuahuan Desert is 235 mm (9.3 in) with a range of approximately 150–400 mm (6–16 in), although it receives more precipitation than most other warm desert ecoregions.

Planting strategies in the desert are different from conventional planting practices, especially in the initial stages. Deserts are regions in which annual precipitation is considerably less than the evaporation, [1] making it difficult for plants and animals that are not specialized to the biome to survive.
As much as 45% of the annual rainfall across New Mexico occurs during the summer monsoon. [33] Many desert plants are adapted to take advantage of this brief wet season. Because of the monsoons, the Sonoran and Mojave are considered relatively "wet" when ranked among other deserts such as the Sahara. Monsoons play a vital role in managing ...
The Colorado Desert is the low area of the Colorado River Valley and surrounding hills and mountains. Plants must survive its hot and dry conditions. [2]: 7 Temperatures can be greater than 120 °F (49 °C). [2]: 7 Annual precipitation is sometimes less than 3 inches (7.6 cm).
There is an annual average precipitation of 2 to 6 inches (51 to 152 mm), ... Less common but distinctive plants of the Mojave Desert include ironwood ...
