Low Technology Irrigation Ideas

Irrigating a farm can double the amount of food it produces. But even with that potential, 80 percent of farmland worldwide is not irrigated, says the UN Food and Agriculture Organization. Part of the problem may be the high cost of irrigation equipment. Also, the prospect of wasteful irrigation techniques raises the specter of environmental damage including water shortages, erosion and soil salinization. Small-scale watering systems can circumvent those issues: Low-cost, low-tech and efficient irrigation is possible. These are ten technologies that work.
