Thank you.
Thank you so much for coming. It's fascinating.
I'd like to centre a bit on the Sudan situation, if you don't mind, just for my own clarification. I was just there in January, after a period of time during which the number of displaced people who were returning to south Sudan had dipped for a period of time. It has now gone up again fairly dramatically as a result of the elections and the referendum that will be coming soon. I'd like to get your view on that and on how you feel the referendum will affect that.
Second, could you address the environmental refugee situation? We keep being told that it could be a hidden card that could suddenly explode on the world. I'd be interested in your comments.
