Irrigation is widely accused of being a wasteful, low-value use of water. There is widespread confusion in the literature about what constitutes ‘‘water use’’ or what is “Water Use Efficiency”. The distinction between diversion and consumption of water is often overlooked. Water Use Efficiency, in the context of irrigation, is frequently interchanged with irrigation efficiency, or is often misquoted. The water balance approach, within defined boundaries, or across different levels of irrigation systems is crucial to assess performance of the systems within the Water Management Area. The fraction of the water abstracted from the source that can be utilised by the plant, can be called the beneficial water use component and optimised irrigation water supply is therefore aimed at maximising this component. “Measure; assess; evaluate; improve”, promotes an investigative water balance approach to improve water use efficiency.


ICID, under its policy to extend its knowledge dissemination wider, is initiating Webinar Services for its members in particular and wider irrigation and drainage community in general. This is the First Webinar being given under “ICID Webinar Services”, to bring a common understanding on the term “Water Use Efficiency” among the water policy makers, irrigation managers and wider water research community.
