ABSTRACT Concern over increasing water scarcity has led to the introduction of the concept of agricultural water productivity and an emphasis on interventions to achieve ‘more crop per drop’. Yet, a strong debate continues on how the concept is to be defined and used. Drawing largely from the irrigation literature, the origins of the concept and its methodological developments are reviewed, and its use in applied work over two decades is discussed. Based on this analysis of conceptual and applied research, key insights into the concept’s contributions and limitations are presented, as well as opportunities for further refinements.

超越“每滴更多作物”:来自二十年农业用水生产力研究的见解

摘要 对日益严重的水资源短缺的担忧导致引入了农业用水生产力的概念,并强调了实现“每滴更多作物”的干预措施。然而,关于如何定义和使用该概念的激烈辩论仍在继续。主要借鉴灌溉文献,回顾了该概念的起源及其方法学发展,并讨论了它在二十多年来的应用工作中的使用。基于对概念和应用研究的这种分析,提出了对该概念的贡献和局限性的关键见解,以及进一步改进的机会。
