What do desert peoples do for their living? 1) Some people mine either copper or other materials in desert mines. 2) They also work on desert farms. 3) Shepherds (or nomads) in the Middle-East go from place to place looking for food and water for their animals.
Deserts are perhaps one of the most difficult places to live. The main characteristic of deserts is that they are extremely dry. Because humans need so much water, surviving in deserts is very difficult. This, in turn, makes it even harder for human life to persist because there is always risk of running out of food.
If sufficient water for irrigation is at hand, any hot, cold, sandy or rocky desert can be greened. Water can be made available through saving, reuse, rainwater harvesting, desalination, or direct use of seawater for salt-loving plants.
SUSTAINABLE FARMING METHODS IN HOT ARID AREAS
- Reduce herd size to limit pressure on vegetation.
- Use solar panels to produce energy, not animal dung.
- Use animal dung to fertilise soils.
- Plant vegetation to feed animals.
- Use effective irrigation (drip and sprinkler irrigation) instead of flood irrigation.
1 : arid land with usually sparse vegetation especially : such land having a very warm climate and receiving less than 25 centimeters (10 inches) of sporadic rainfall annually. 2 : an area of water apparently devoid of life. 3 : a desolate or forbidding area lost in a desert of doubt.
Some dry farming practices include:
- Wider than normal spacing, to provide a larger bank of moisture for each plant.
- Controlled Traffic.
- Minimal tilling of land.
- Strict weed control, to ensure that weeds do not consume soil moisture needed by the cultivated plants.
In deserts and related biomes, crops will grow more slowly (Except cactuses), and in Jungle biomes crops such as water melons and cocoa beans will grow faster than in other biomes. Cacti would blossom in night in desert as well!
This is why farmers add nutrients to their soils. This maintains the soil fertility, so the farmer can continue to grow nutritious crops and healthy crops. Farmers turn to fertilizers because these substances contain plant nutrients such as nitrogen, phosphorus, and potassium.
These soils are only nutrient-rich for a thin layer. Desert soils are nutrient poor because of the low organic matter and because the lack of water slows the weathering process that can release nutrients from soil minerals.
Desert soils are dry, and tend to have clumpy vegetation. Desert soils form in areas where the demand for water by the atmosphere (evaporation) and plants (transpiration) is much greater than precipitation.
The time needed to form a soil depends on the latitude: in environments characterized by a mild climate, it takes 200-400 years to form 1 cm of soil. in wet tropical areas soil formation is faster, as it takes 200 years. in order to accumulate enough substances to make a soil fertile it takes 3000 years.
Of interest, climate is one of the five soil forming factors and has a significant influence on the properties of soil. Soils in warmer or wetter climates are more developed than soils in cooler or drier climates. Warm conditions promote the chemical and biological reactions that develop parent material into soil.

Aridisols (or desert soils) are a soil order in USDA soil taxonomy. Aridisols (from the Latin aridus, for "dry", and solum) form in an arid or semi-arid climate. Aridisols have a very low concentration of organic matter, reflecting the paucity of vegetative production on these dry soils.
Black soils are mineral soils which have a black surface horizon, enriched with organic carbon that is at least 25 cm deep. A base saturation in the black surface horizons ≥50%.
The dry condition of deserts helps promote the formation and concentration of important minerals. Gypsum, borates, nitrates, potassium and other salts build up in deserts when water carrying these minerals evaporates. Minimal vegetation has also made it easier to extract important minerals from desert regions.
5 Edible Desert Plants
- Prickly Pear Cactus – Opuntia Velutina. One of the most common desert foods is the prickly pear.
- Mesquite – Prosopis spp. You've probably heard of Mesquite as a smoky flavoring on meats and chips.
- Desert Chia – Salvia hispanica.
- Agave – Agave spp.
- Piñon Pine – Pinus spp.
ZONE 10: High desert areas of Arizona and New MexicoIt also includes parts of southern Utah and Nevada, and adjacent California desert. Zone 10 has a definite winter season—75 to more than 100 nights below 32°F (0°C).
LEVEL 1. The easiest trees to grow in the desert. These include figs, pomegranates, and mulberries. They can be planted into native clay and do not require any specialized care.
Foxes, spiders, antelopes, elephants and lions are common desert species.
- Desert fox, Chile.
- Addax antelope.
- Deathstalker scorpion.
- Camel.
- Armadillo lizard.
- Thorny Devil.
- Rock Hopper penguin.
Subshrubs/Perennial Flowers
- Bush monkeyflower / Mimulus aurantiacus.
- California fuchsia / Epilobium canum (Zauschneria californicum)
- Desert four-o'clock or Wishbone bush/Mirabilis laevis.
- Desert mallow / Sphaeralcea ambigua.
- Desert marigold/Baileya multiradiata.
The easy formula was developed by the Norwegian scientist Kristian Morten Olesen, has revolutionized agriculture in dry regions and has the potential to be used on a global scale. The LNC technique, or Liquid NanoClay, is capable of transforming poor sandy soils into high-yielding arable land.
Fruit of the desertGideon Oron from Ben-Gurion University of the Negev says salt water, too, can be used to cultivate plants in the desert - but that requires a newer model called subsurface drip irrigation (SDI), where drip pipes are buried deep below the earth's surface and the plants' roots.
