In the Euphrates and Tigris region, called Mesopotamia, ancient civilizations lived from 4,000BC. Thanks to irrigation, the ‘fertile crescent’ was created. Conflicts between the states of Umma and Lagash happened 4,500 years ago for the control of irrigation canals. Since 2,400BC, the region has been suffering salt accumulation problems. Many of those civilizations disappeared because of the abandonment of irrigation systems.
