Everything about Desert Farming totally explained
Desert farming generally relies on
irrigation, as it's the easiest way to make a
desert bloom. In California, the
Imperial Valley is a good example of what can be done.
Australia,
Israel, and the
Horn of Africa are also places with interesting desert agriculture.
One problem associated with raising traditional plants in a desert is depletion of the
ground water.
Drip irrigation is one way to reduce the overall water demand. Another is to
grow crops that are acclimated to the desert, such as
jojoba,
Date palms, and
citrus.
Farming without irrigation (Sonoran Desert)
Native Americans of the
Sonoran Desert have long practiced (and continue to practice) desert agriculture
without irrigation. This is highly dependent upon both winter snow and rain and summer
monsoonal weather patterns which move moist tropical air from the
Gulf of Mexico into northern
Mexico and the southwestern US states of Arizona, Utah, New Mexico, and Colorado. This moist air, combined with the intense solar heating of the ground, can cause the development of substantial
thunderstorms that can deluge some portions of the ground with great amounts of water over a short time. While the surface quickly becomes dry, and there's much runoff of the water into normally dry streams and riverbeds, a substantial portion is absorbed into the upper soil levels. To take advantage of this condition for agriculture it's essential that crops be started early in the season, where they utilize residual winter water from
Pacific Ocean storms originating in the
Gulf of Alaska and other Winter Pacific storms from the tropics (the "Pineapple Express"). The early sprouts from planted seeds (mostly beans, squash, and maize) are protected by starting them in small dug holes, where they're both closer to the winter water remaining in the soil and protected from the early spring
frosts. Despite its success over a period of (likely) up to 14,000 years, there have been great difficulties with this form of agriculture since a drought beginning in 2002, with
global warming suspected in changing weather patterns, and problems with ground water depletion due to extraction for modern conventional irrigated agriculture, metropolitan lawns, industrial purposes, and coal slurry pipelines (the latter now stopped through action by
Navajo tribal authority).
The native Americans practicing this agriculture included the ancient and no longer present
Anasazi, the long–present
Hopi, the
Tewa,
Zuni, and many other regional tribes, including the relatively recently arriving (about 1400 CE) Navajo. These various tribes were characterized generally by the Spanish occupiers of the region as
Sinagua Indians,
sinagua meaning "without water", although this term isn't applied to the modern Native Americans of the region.
Owing to the great dependence upon weather, an element considered to be beyond human control, substantial
religious beliefs, rites, and prayer evolved around the growing of crops, and in particular the growing of the four principle corn types of the region, characterized by their colors: red, yellow, blue, and white. The presence of corn as a spiritual symbol can often be seen in the hands of the "Yeh" spirit figures represented in Navaho
rugs, in the rituals associated with the "Corn Maiden" and other
Kachinas of the Hopi, and in various
fetish objects of tribes of the region.
Desert Farming in Egypt
Over a decade ago, Egypt has aimed at massively targeting the desert for farming due to the availability of a wide desert area in Egypt. Water supply for desert farming in Egypt has been mostly dependent on digging wells. Irrigation is done by water drops in contrast to the irrigation by submersion used in the River Nile valley which Egyptian farmers have been used to for thousands of years.
