This article reviews the origins and methodological developments of the concept of agricultural water productivity, as well as its application in research over the past two decades. Key insights into the contributions and limitations of the concept are presented, along with opportunities for further refinements.
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.
