The ancient civilization known for its extensive use of canals for irrigation is the Mesopotamian civilization, particularly the Sumerians. Located in the fertile region between the Tigris and Euphrates rivers, Sumerians developed advanced irrigation systems to manage water for their agriculture. By constructing canals and dikes, they could control flooding and distribute water to crops, allowing for increased agricultural productivity. This innovation enabled the growth of cities, such as Ur and Babylon, which became centers of trade, culture, and administration. The success of Sumerian irrigation techniques greatly influenced subsequent civilizations in the region and laid the foundation for future agricultural practices.
