Traditional desert farming systems have long been established in North Africa, irrigation being the key to success in an area where water stress is a limiting factor to growth. Techniques that can be used include drip irrigation , the use of organic residues or animal manures as fertilisers and other traditional agricultural management practices.
Desert ecology is the study of interactions between both biotic and abiotic components of desert environments. A desert ecosystem is defined by interactions between organisms, the climate in which they live, and any other non-living influences on the habitat. Deserts are arid regions that are generally associated with warm temperatures; however ...
Generally evaporation exceeds rainfall in these ecoregions. Temperature variability is also diverse in these lands. Many deserts, such as the Sahara, are hot year-round, but others, such as East Asia's Gobi Desert, become quite cold during the winter. [1] Temperature extremes are a characteristic of most deserts.
One way of mapping terrestrial biomes around the world (except the Antarctic Tundra) A biome (/ ˈ b aɪ. oʊ m /) is a distinct geographical region with specific climate, vegetation, and animal life. It consists of a biological community that has formed in response to its physical environment and regional climate. [1]
Landforms caused by wind erosion vary greatly in characteristics and size. Representative landforms include depressions and pans , Yardangs , inverted topography and ventifacts . No significant populations can survive in tropical deserts due to extreme aridity, heat and the paucity of vegetation; only specific flora and fauna with special ...
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.

The Little Sandy Desert connects to the Great Sandy Desert and is similar in terms of landscape and vegetation. The Western Desert , which describes a cultural region of Australia's indigenous people, includes the Gibson, Great Victoria, Great Sandy and Little Sandy deserts in the states of Northern Territory, South Australia and Western Australia.
A semi-arid climate, semi-desert climate, or steppe climate is a dry climate sub-type. It is located on regions that receive precipitation below potential evapotranspiration, but not as low as a desert climate. There are different kinds of semi-arid climates, depending on variables such as temperature, and they give rise to different biomes.
