( CNN ) -- Less than a week after the United Nations declared an end to the famine in Somalia , a new report from the world body says millions of people in South Sudan will now face hunger if urgent action is not taken . The report released Wednesday by the Food and Agricultural Organization of the United Nations ( FAO ) and the World Food Program ( WFP ) says that fighting in the northern border region and ethnic clashes in many other parts of South Sudan has created a level of food insecurity that could nearly double in the next year . `` Poor harvests , increased demand , rapidly rising prices , displacement and a large number of returnees have all contributed to the situation , '' the report says . `` The situation is dire , '' said Chris Nikoi , WFP 's country director in South Sudan . `` This is a rapidly approaching crisis that the world can not afford to ignore . '' Under a normal functioning market , food insecurity and increased demand might have been addressed , the report says , but border closures that link the newly independent South Sudan to Sudan have disrupted the usual supply of food commodities to South Sudan 's markets . The fighting along the disputed border regions and ethnic clashes over cattle in multiple South Sudanese states is responsible for the displacement of tens of thousands in the country . The U.N. reported that more than 120,000 people might have been affected in South Sudan 's Jonglei state after clashes between the Murle and Lou Nuer tribes have killed hundreds , possibly thousands . Sudan and South Sudan will also be entering another round of talks this week to settle a bitter dispute over oil that seems to be edging the two countries toward more conflict . The WFP says it is scaling up operations to reach the millions of people at risk , but is trying to meet its goal of $ 160 million in donor support . The FAO is hoping for $ 23 million in donor support .
