Abstract
Increasing the productivity of available water resources is central to producing more food, fighting poverty, reducing competition for water, and ensuring that there is enough water for the environment. For sustainable water resources management, a better understanding of the link between productivity changes and their impact on different users within the same basin is required. Therefore it is imperative to develop common water accounting procedures for analyzing the use, depletion, and productivity of water at the plant, field, irrigation system, and basin scales. This chapter emphasizes the need for measuring water productivity at different scales because different actions are needed to enhance water productivity at each level. The chapter also provides a discussion on potential interventions and strategies that can be used to enhance productivity of water at different scales. Successful implementation of these interventions requires more detailed technical and economic analysis to ensure sustainability.
