How did irrigation help farming in the fertile crescent?

Irrigation significantly enhanced farming in the Fertile Crescent by providing a reliable water supply to crops, which was crucial in an area with variable rainfall. This agricultural technique allowed farmers to cultivate larger areas of land, leading to increased crop yields and the ability to grow a diverse range of crops. As a result, irrigation contributed to the development of settled communities and the rise of complex societies in the region. The surplus food produced also supported population growth and trade, further advancing civilization.
