Why was irrigation an important development?

Irrigation was an important development because it allowed for the controlled supply of water to crops, significantly increasing agricultural productivity. This innovation enabled societies to cultivate larger areas of land and grow surplus food, which supported population growth and the development of complex civilizations. Additionally, irrigation facilitated the establishment of permanent settlements, as communities could rely on consistent food sources rather than seasonal rainfall. Ultimately, it played a crucial role in the rise of urban centers and the advancement of economic and social structures.
