The crisis is another hurdle for the war-ravaged south ahead of a referendum on independence in January, which some analysts fear will be hindered by a worsening humanitarian situation with almost half the region’s 8 million population short of food.
“In the last one month 57,135 people have been displaced by the floods,” said the south’s undersecretary for health Olivia Lomoro, adding that many were at risk of malaria and water-borne diseases.
She said Aweil, the capital of Northern Bahr El-Ghazal state, was ground zero for the crisis. The area was one of the hardest hit in a two-decade long civil war and is already heavily reliant on international food aid.
The south’s health minister, Luka Monoja, told a news conference that rains were expected to continue until October, meaning the worst may be yet to come.
Northern Bahr El-Ghazal is due to receive some of the 1.5 million people the government plans to bring home from the north before the January vote.
The United Nations says it has already helped feed some 4 million southerners in 2010 and warns voting preparations may heap more stress on the region.
Analysts fear the mounting humanitarian crisis will add to problems of insecurity ahead of the January 9 vote and destabilize a newly independent state should the referendum pass.
The mainly Christian and animist south has fought a bitter civil war against the mainly Muslim north over ethnicity, ideology and resources for all but a few years since 1955.
The plebiscite is the climax of a 2005 peace deal ending Africa’s longest running civil war.
