Detailed explanation-1: -The first irrigation techniques were first invented by the Sumerians around 5, 500 years ago. The Sumerians realized that by creating levees to hold back river waters, they could control the amounts they needed to grow important crops.
Detailed explanation-2: -The Sumerians (people who lived in Southern Mesopotamia) did not get their food by hunting and gathering. Instead they produced their own food by farming. To help them farm the dry land they learned to irrigate their fields.
