Farming: In some areas of hot deserts, irrigation systems are used to cultivate crops such as dates, figs, and melons. Subsurface water sources, such as aquifers, can be accessed through wells or canals to support agriculture.
Animal husbandry: Nomadic herding of animals like camels, goats, and sheep is common in hot deserts. These animals are well-adapted to desert conditions and provide milk, meat, and transportation.
Hunting and gathering: In some desert regions, indigenous communities rely on hunting and gathering wild plants and animals for sustenance. This may include hunting gazelles, rabbits, and other desert-dwelling species, as well as gathering edible plants, fruits, and nuts.
Importing: Due to the harsh conditions, many desert regions rely on importing food from other areas with more favorable agricultural conditions. This may involve trading goods or using trade routes to bring in necessary supplies.
Special techniques: Some innovative methods have been developed to obtain food in hot deserts. For example, aquaponics, which combines fish farming with hydroponics (growing plants in water without soil), can be used to produce food in desert environments with limited water resources.
