A land dispute that resulted from a river changing its course due to heavy rains some 50 years ago continues to vex neighbouring agricultural communities along the Burundi-Rwanda border. The latest incident in the Sabanerwa land dispute occurred in early January when Burundian farmers crossed to one side of the River Kanyaru in a bid to cultivate land at Sabanerwa. During the incident, Rwandan troops, accompanied by the governor of Rwanda's Butare province, massed at the riverbank to prevent Burundians from cultivating the land.
