Improved rainwater harvesting system promising

Ridge and furrow rainwater-harvesting (RFRH) systems with mulches were first researched in the flat, lowland, semiarid conditions of northwest China to improve water availability and to increase crop production. In RFRH systems, plastic-covered ridges serve as rainwater harvesting zones, and bare or mulched furrows serve as planting zones. The systems are becoming increasingly recognized and are being promoted in many parts of the world as a means to improve large-scale production operations.
