Nasir Abdullahi is sitting in a mall in downtown Abuja, sipping fresh juice and eating plantain chips. Small, distinguished with an embroidered cap, Nasir looks like your typical Northern Nigerian businessman, but he's also a farmer.
A few years ago he got a call from an employee on his millet farm in Jigawa, Nigeria.
"He was even crying when he called me," Abdullahi says. "I said, 'Talk!' He said, 'There is something serious, there is something serious!' I said, 'Did anybody die? What is it?' He said, 'No, it's cattle herdsmen.'"
Abdullahi got in his car and drove a few hours to the farm. He learned the herdsmen and their cows had spent the night, destroying some of his crops.
Later, his employees told the herdsmen to leave. That's when the fight began.
