Abstract
Miscalculating the volumes of water withdrawn for irrigation, the largest consumer of freshwater in the world, jeopardizes sustainable water management. Hydrological models quantify water withdrawals, but their estimates are unduly precise. Model imperfections need to be appreciated to avoid policy misjudgements.
摘要
世界上最大的淡水消费户——农业，在计算灌溉用水量时出现了失误，这对可持续水资源管理构成了威胁。水文模型可以量化用水量，但它们的估计往往过于精确。为了避免政策误判，需要认识到模型的不完善。
