Water is crucial to crops and is facing rarefication across the world. Agriculture must improve its productivity to meet increasing demands for food in the coming years and irrigation is a key component for achieving these increases. However, the predicted growth in irrigation needs and the coming lack of qualified manpower will require more intelligence to be built to assist decision making in irrigation to conserve water and improve crop productivity.

水对农作物至关重要，但世界各地都面临着水资源稀缺的问题。农业必须提高生产力，以满足未来几年日益增长的粮食需求，而灌溉是实现这些增长的关键组成部分。然而，预计灌溉需求的增长和即将到来的合格人力资源的缺乏将需要建立更多的智能来协助灌溉决策，以节约用水并提高作物生产力。
