Interest: Agriculture

870 million people worldwide are chronically undernourished. Irrigating crops is a simple solution that can double the amount of food a farm produces. But as much as 80 percent of farmland worldwide is not irrigated. Tested machines and new innovations meet that need and others on the farm. From pumps powered by diesel or the sun, drip tubes, mobile apps for weather and market information, low-cost utility vehicles, shellers, driers and much more, innovative design is putting more food on the world’s tables.
