Yusuf nuhan, a 65-year-old Chadian villager, remembers when he could sail across Lake Chad to visit markets and relatives. His village used to be rich with thousands of cattle, he says. But three years ago, jihadists from Boko Haram attacked and took everything. "They just killed people. We don't know why," he says, fiddling with his prayer beads. "The government has done nothing to help us." He and his family fled to Baga Sola, a small, dry market town a few kilometres away. They set up camp outside the walls of a United Nations base and prayed that one day they could return to their land. But over the past few months, there has been a resurgence of Boko Haram attacks, killing dozens of soldiers. In theory Mr Nuhan could walk to his childhood home in two hours, but he has given up hope of ever seeing his land again.
