A look at history is, at times, a look at irrigation. Often civilizations have blossomed once agriculture could be efficiently consistent. This consistency is made possible with irrigation. Perhaps it is unwise to populate and build an area to the point where food is dependent on irrigation but not so foolish if irrigation is wisely managed. And currently massive numbers would need to be relocated if irrigation was not utilized. Supplying the right amount of water to forage plants at the right time with minimal loss is the goal of wise irrigation. There are many factors that contribute to that objective. Knowledge of several areas is needed: equipment, system design, plant species, growth stage, root structure, soil composition, and land formation. Proper irrigation management takes careful consideration and vigilent observation.
