How do villagers who live in the desert obtain water for agriculture?

Villagers in desert regions often rely on several methods to obtain water for agriculture, such as digging wells to access underground aquifers or using traditional water harvesting techniques to capture rainfall. They may also employ drip irrigation systems to conserve water and maximize efficiency. Additionally, some communities utilize surface water from nearby rivers or lakes, if available, and implement crop rotation and drought-resistant plants to optimize their agricultural practices in arid conditions.
