AbstractRecognizing the need for water efficient food production systems in semi-arid regions of the world, a Desert Strip Farming system (a method of water harvesting) was designed and constructed at Page Ranch to determine the feasibility of double cropping at that location. Crops grown during two consecutive winters offered only limited data due to animal problems, but the intervening summer crop of sorghum demonstrated the potential of the system with significant yields on less than 150 millimeters of rainfall. A detailed account of the design and construction of the system is included, as well as guidelines for determining the applicability of such a system to other semi-arid regions of the world. Five specific locations are outlined as examples of regions that could support double cropped agriculture using water harvesting agrosystems.
