Approximately half of the agricultural land in Israel is irrigated and the majority of that (around 60%) is irrigated with drip systems. The widespread implementation of drip irrigation has made a major contribution to the increase in irrigation water use efficiency (WUE) in Israel, in terms of production per irrigation unit. Irrigation WUE in Israel has increased steadily since the 1960s and doubled by 2000-2010. Yet, it hardly changed after 2011. One approach that can potentially increase water use efficiency is precision irrigation or variable-rate irrigation.
