Both the Sudanese government and the Sudan People's Liberation Movement/Army (SPLM/A) have said that once a peace agreement has been signed, the return of the country's refugees and internally displaced to their homes will be a key priority. Both sides are keen to see people move freely after 36 years of conflict out of 47 since independence. But for the local authorities, donors, UN and aid agencies grappling with the prospect of 570,000 Sudanese refugees, and between 3 million and 4 million displaced returning home en masse, the challenges ahead are staggering.
