This chapter discusses the role of supplemental irrigation in increasing water use efficiency and yields of rainfed crops. Topics covered include: the reasons for low rainfall water productivity; supplemental irrigation as a response to shortages of soil moisture; sources of water for supplemental irrigation; supplemental irrigation impact on rainfed agriculture; and maximizing supplemental irrigation benefits. The economic of supplemental irrigation is also discussed. Finally, summaries of two case studies, one in Syria and another in Tunisia, for assessing the potential of supplemental irrigation are presented.
