It is an antiquated agrarian system and may have been honed as ahead of schedule as 5000 B.C. along the banks of such consistently flooding streams as the Nile.

The advancement of preoccupation dams and of water-lifting machines allowed the water system of terrains lying over those typically come to by floodwaters. Remainders of these antiquated structures have been found in Egypt, where all farmlands are flooded; Iraq; Lebanon; Syria; China; India; Peru; Mexico; and the United States.
