The Rift Valley Institute recently published a 52-page study titled "Politics, Power and Chiefship in Famine and War: A Study of the Former Northern Bahr el-Ghazal State, South Sudan" by Nicki Kindersley, Cambridge University.
The study investigates how customary authorities on South Sudan's border with southern Darfur have managed repeated wars and famines since the 1960s, both for the communities that they claim to represent and for their own survival and benefit.
