Relocation...

In my first visit to South Sudan in 2008 I was stunned by the sheer number of people in transit. The vast majority were on foot, like a trail of ants on long, straight, dusty roads. Some had bikes. Other than SPLA (army), UN and NGOs, there were very few vehicles.
Now there is much better infrastructure for transportation. Public transport operates between most major towns and, while there still thousands walking the roads, not so many are making the long journey to a new home.
It is not that internal migration is decreasing. Now it is better organised and coordinated between the Government, UN and local authorities to enable the return of hundreds of thousands who had fled over previous decades.  Returnees that have been registered may be provided with basic supplies when they reach their destination until they can become self-sufficient.
To give an idea of the number of people relocating within Sudan, here are some statistics from the most recent UNMIS report.  During the past week...

• 3070 individuals passed through the transit hub in Kosti (a port town on the Nile south of Khartoum) in spontaneous migration
• 16,674 people were tracked through Kosti in organised returns
• 51 busses carrying 2964 people departed Khartoum for Abyei
• SSRRC estimate 87,000 will eventually return to Northern Bahr Al Ghazal
