I think Mark probably knows more and has a better idea about that than I do. There were, however, fears in Juba that the so-called djellaba Arab traders would be expelled or worse. They're a core part of the economy in Juba. They're good traders, but they're not citizens. When I was there, they were stopping people in vehicles and so on to check their registration. We were told they might even go door to door in our camp to check who we were, but that didn't happen.
The one problem is the possible expulsion of northerners of Arab descent who are living and working, often very productively, in the south. The other possibility, as we heard from Mark, is that anywhere between half a million and a million and a half people might move into Juba. Now Juba has grown from 125,000 maybe five or six years ago to, by some estimates, over a million. It's a remarkably stable community given the piles of foreign aid helping out. In the next half year, if another half million people come in, that could be the biggest problem of all--not to mention these refugee camps.
Maybe Mark has something to say about it.
