Improving the efficiency of irrigation systems by itself, while beneficial and indispensable in the Middle East North Africa region and other arid or semi-arid regions of the world, does not translate into real water savings in the hydrological cycle. Often, these improvements lead to an increase in water consumption and reductions in aquifer recharge/ return flows, thus the importance of setting up a comprehensive accounting system of water use. At present we have proven technologies for water accounting that combine remote sensing with hydrological models and cutting-edge science. We need to emphasize this more in our operations dealing with irrigation modernization and/or improvements. Next Friday, April 26, the World Bank will host one of the gurus on water accounting, Dr. Wim Bastiaanssen, who will give a lunch-time talk on the subject.
