At least a thousand families have arrived in southern Sudan from the north, ahead of a referendum due next January on whether the south should secede and form its own country.
Encouraging people to return home for the referendum is just the first step - making sure adequate services are available for those who do is a bigger challenge.
The returnees have come to register to vote ahead of the planned referendum on independence for the region in January.
