How did ancient civilizations from the dessert find food?

Ancient civilizations in desert regions often relied on a combination of agriculture, trade, and foraging to find food. They cultivated drought-resistant crops like barley and millet using irrigation techniques, such as canals and wells, to access water sources. Additionally, they engaged in trade with neighboring regions for surplus goods and hunted or gathered wild plants and animals available in their environment. These strategies allowed them to adapt to the harsh conditions of the desert and sustain their communities.
