For Ugandan farmer Ken Sakwa, a mobile phone is indispensable. “That phone does everything for him,” says Zachary. Previously, Sakwa only farmed his own land. These days, he’s also a small-scale food broker, buying crops from other local farmers and selling them in the city or wherever they’ll fetch the highest price. The phone lets him quickly negotiate prices and arrange transportation. “There’s no wasted effort,” Zachary says.
