The world’s increasing population means the need for food supply to guarantee survival has also increased. An integral part of the food production process is water, central to everything, from crop cultivation to processing. Water is a precious and limited resource globally, and water-efficient farming has been a global priority for a long time. Now more than ever, it requires all the necessary attention it can get to cater to the world’s needs. However, the inefficient irrigation systems mean agriculture operates below potential, contributing to reduced yields in farm produce, an inconsistent rate of farm production, and scarcity of food, notably on the African continent.
