This map shows the provinces of the Sudan, the boundary defining the north and south in the Comprehensive Peace Agreement of 2005, and the three areas of Abyei, Southern Kordofan and Blue Nile which lie north of the line but for which special constitutional provisions have been made. Over history people have repeatedly found refuge in the rugged mountains and deep valleys where western Ethiopia meets the eastern fringes of the Sudan. The map shows Chali, the Sudanese village near Kurmuk which was the centre of Uduk country up to 1987, and also Bonga, the refugee settlement near Gambela in Ethiopia where they arrived in 1993. In the course of trekking, they had found themselves as far west as Nor Deng, near Nasir in the Upper Nile.
