Desert farming is the practice of developing agriculture in deserts. As agriculture depends upon irrigation and water supply, farming in arid regions where water is scarce is a challenge. However, desert farming has been practiced by humans for thousands of years. In the Negev, there is evidence to suggest agriculture as far back as 5000 BC. [1]
Many desert ecosystems are limited by available water levels, rather than rates of radiation or temperature. Water flow in these ecosystems can be thought of as similar to energy flow; in fact, it is often useful to look at water and energy flow together when studying desert ecosystems and ecology. [3]
Human disturbance poses the number one concern to this fragile ecosystem. The Sonoran desert contains the two large cities of Tucson and Phoenix, Arizona, which contain over 3 million people. [15] These dense human populations deplete the water table of the entire desert and are sending the desert towards desertification.
The Mojave Desert Land Trust is working to scout, catalogue, collect and preserve millions of seeds from 250 species and counting in a race to save an ecosystem.
The Great Basin Desert is part of the Great Basin between the Sierra Nevada and the Wasatch Range in the western United States.The desert is a geographical region that largely overlaps the Great Basin shrub steppe defined by the World Wildlife Fund, and the Central Basin and Range ecoregion defined by the U.S. Environmental Protection Agency and United States Geological Survey.
The "North American Desert" is also the term for a large U.S. Level 1 ecoregion (EPA) [1] of the North American Cordillera, in the Deserts and xeric shrublands biome (WWF). The continent's deserts are largely between the Rocky Mountains and Sierra Madre Oriental on the east, and the rain shadow –creating Cascades , Sierra Nevada , Transverse ...
A desert is a landscape where little precipitation occurs and, consequently, living conditions create unique biomes and ecosystems. The lack of vegetation exposes the unprotected surface of the ground to denudation .
California has two high deserts: the Mojave Desert and the Great Basin Desert. The Mojave Desert ecoregion is marked by the presence of Joshua trees. [3] The dry cold Great Basin desert of California consists of the Owens Valley, and is classified into Great Basin shrub steppe by the WWF, [4] and into the Central Basin and Range ecoregion by ...
