Even assuming that the citizenship issue is resolved satisfactorily, there is a possibility there could be large movements of populations after the referendum, either from south to north or from north to south.
CIDA has had a number of programs dealing with the return of IDPs, and did particularly after 2005. I think they found that it was more effective to address the kinds of services needed for returning IDPs at the community level rather than targeting IDPs specifically. The IDPs coming back, even if there were resettlement or reintegration packages aimed at those IDPs, were very often not resettling and were turning back to Khartoum or wherever they'd been, because the community in which they were supposed to be integrating simply wasn't ready. There was no employment; there weren't services and so forth. CIDA therefore, as part of its activities, is broadening that to a wider pool of public services, through the Basic Services Fund and other things.
I believe the member also asked about south-south violence. This has been a real problem, and it has been a problem throughout the conflict--the civil war and after. The year 2009, which was a year of peace, saw 2,500 people killed in southern Sudan in inter-ethnic violence. This year it's been somewhat better, but it's still disturbing.
This is one of the reasons we feel it's so important to build up the capacity of the southern Sudan police force through training, and to build up and support UNMIS in its stabilization law.
