"While the tensions and conflicts in Darfur are currently in the headlines, the report warns that other parts of the Sudan could see resumptions of historical clashes driven in part by declines in environmental services.
This is particularly the case in some north-south border zones. In the Nuba mountains region in Southern Kordofan, for example, the indigenous Nuba tribe expressed concern over the damaging of trees and other vegetation due to the recent presence of the camel-herding Shanabla tribe. Like many pastoralist communities, the Shanabla have been forced to migrate south in search of adequate grazing land lost in the north to agricultural expansion and drought. Some Nuba warned of 'restarting the war' if this damage did not cease."
