Millions of Sudanese still live in fear of violence, a year after the peace deal ended 21 years of war between north and south, aid agencies say according to BBC Online Sunday.
Many Sudanese have little to celebrate because of conflict in the western province of Darfur and insecurity in the south and east, they say.
And communities in the south still lack food and water, despite pledges made by donors last year to provide 4,5 billion US dollar.
However, some 500.000 southern Sudanese are expected to return home this year.
The UN special representative in Sudan, Jan Pronk, has said that although the peace agreement is still holding, the division of Sudans oil revenue remains a major hurdle.
In the agreement provision was made for Sudans oil wealth to be shared equally between north and south, BBC adds.
