Explanation:
<em>Irrigation is the application of controlled amounts of water to plants at needed intervals. Irrigation helps to grow agricultural crops, maintain landscapes, and revegetate disturbed soils in dry areas and during periods of less than average rainfall</em>
Farming is a process that requires constant supply of water to aid crop production. During the ancient civilization in Mesopotamia, farmers grew crops in lands that had little rainfall and inadequate supply of water. What they did was to develop a means of controlling the flow of water from the river and channeling it to their farms. This was done by setting up canals and irrigation ditches to redirect the water to their farms. Regulators were developed to control the level of water in the ditches and canals, making it accessible to the farmers. At that time, each farmer was permitted to use a certain amount of water. The farmers take turn to water their field. When it was the turn of a farmer, the regulator is adjusted to allow the outflow of water from the canal into an irrigation ditch and finally, into the farmer's field.
