UN launches 3-month emergency operation in S. Sudan NAIROBI, Jan. 13 (Xinhua) -- The UN World Food Program (WFP) on Monday launched a three-month operation to scale up humanitarian assistance to South Sudanese affected by the crisis. The WFP's East and Central Africa Regional Director Valerie Guarnieri said the 57.8 million U.S. dollars aid will be provided to about 400,000 IDPs, including specialized nutritional support for new mothers and young children who are most at risk from a disruption in their food supply. "But while we and our partners are reaching more people every day, we still face difficulties accessing some areas, and the looting of food and other assets from a number of our compounds and warehouses around the country, most recently in Bentiu on Thursday, greatly complicates our relief efforts," Guarnieri said in a statement. The humanitarian situation in South Sudan has deteriorated rapidly since fighting broke out in mid-December, causing not only the loss of life and displacement, but also disrupting agricultural development and humanitarian activities crucial to the survival and future livelihoods of millions. According to UN, the impacts on diversified livelihoods in four of South Sudan's 10 states are generating an alarming risk of food insecurity and malnutrition. The crisis in the world's youngest country has forced over 200, 000 people to flee their homes in search of safety, when many parts of the country should be the harvest season. The UN food agency has expressed fears that the impact on food security will be significant for some time even if the political negotiations are successful. Food insecurity was a major challenge for South Sudan even before the conflict, and unrest has disrupted commercial supplies to local markets in much of the country. Guarnieri said WFP staff have mobilized quickly to provide immediate relief to people seeking safety across South Sudan's borders. "But all of our refugee assistance programs in the region were already facing severe funding shortfalls before this crisis, and a new influx of refugees will strain their resources even further," Guarnieri said. The agency also condemned looting of humanitarian supplies, saying its food stocks which pre-positioned at nearly 100 sites around the country to facilitate the relief effort are also at risk. "So far WFP estimates that 10 percent of its food in the country has been looted -- enough to feed some 180,000 people for a month," it said. WFP Deputy Country Director Eddie Rowe called on all parties to protect civilians and safeguard humanitarian assets -- such as food stocks - so that they can be used to provide critical relief, especially for women and children, affected by the violence. We join our partners in urgently appealing to both sides to allow access for humanitarian agencies to safely provide assistance to those in need. The WFP is also assisting tens of thousands of refugees who have fled across South Sudan's borders into neighboring countries, including Uganda, Ethiopia and Kenya.
