| Irrigation Device Pulls Water From the Air in Driest Conditions A student at Australia's Swinburne University this week received the James Dyson Award for a device he says is capable of harvesting moisture from the air for use in James Dyson AwardVIDEO: Edward Linnacre describes the Airdrop irrigation, even in the world's driest places. Developed by Edward Linnacre, the Airdrop is a wind- or solar-powered device that sucks air underground through a coiled metal pipe, where the cooler temperature of the surrounding soil slowly causes it to condense. The device ultimately collects the water in an underground tank before it is pumped back to the roots of nearby crops via a sub-surface drip irrigation system. |

| Urban Hydroponics: A Model for Feeding a Growing Population Using Fewer Resources? by Cole Mellino As the global community considers the interwoven issues of food access, resource scarcity, increased urbanization and climate change, innovation in the agriculture sector is blossoming. We're going to continue to highlight important projects and scientific developments in agriculture that help address those problems. And sometimes, those answers are very simple ones. Earlier this summer, New York City became home to the nation's first commercial urban hydroponic greenhouse. Gotham Greens, the company that operates the 15,000 square-foot facility in Brooklyn, has harvested and delivered the first of its 100 annual tons of local and organic vegetables and herbs. |

| A $3 Pear: Food Prices that Even Oprah Can't Stomach? by Cole Mellino Food prices are rising so consistently, Americans are starting to do crazy things. Earlier this month, the UN predicted food prices would continue to get more volatile. Now, the U.S. Department of Agriculture is predicting an increase of 3.5% to 4.5% for American retail food inflation this year. Retail inflation increased just 0.8% last year. The changes in retail prices are making many cash-strapped shoppers go to great lengths to get good deals, according to a recent story in the Wall Street Journal. "If I don't think it's a good deal, I don't buy it," Evelyn Jackson, a student at Columbia College in Chicago said Tuesday as she loaded groceries into her car, which she uses for comparison shopping despite the high cost of gasoline. |
