This chapter focuses the use of water harvesting systems for the improvement of agricultural productivity in dry areas. The components of a water harvesting system, for it to be applicable to rainfed agriculture, are given. The different types of water harvesting systems are described. The potential of water harvesting in arid and semiarid regions are discussed. Summaries of two cases, one in Syria and another in Tunisia, for assessing the potential of water harvesting in West Asia and North Africa, respectively, are presented. The economics of water harvesting is emphasized. Finally, the use of water harvesting systems for supplemental irrigation and mitigating desertification is discussed.
