African Leaders Address Refugee ProblemsAs the number of displaced persons in Africa reaches 17 million, leaders on the continent and representatives of international organizations are attending a refugee summit in Ethiopia. Khabele Maltosa, head of the African Union Commission on Political Affairs, says Africa needs to tackle what he sees as the causes of the crisis. "The majority of forcibly displaced are a result of violent conflict. So, we need to address the root causes of conflict in the continent," he said. "We have to address inequality, poverty, unemployment that generate tension in the continent. ... A lot of political violence comes as a result of [the] election, so we need to address the issue … to make sure that the elections are democratic, credible and peaceful." UNHCR's representative to the African Union, Cosmas Chanda, hopes participants at this year's summit can work to make it easier for refugees to return home. "We are talking about annexes of 17 million people … displaced in the continent. That by itself [is] very depressing," Chanda said. "We would like to see a situation which people return to their places where they normally stay. We would like to see a situation where further displacement [is] prevented." The U.N. says Uganda hosts 1.4 million refugees, the world's second largest refugee population after Turkey. Most refugees in Africa come from South Sudan, where 2.4 million people are displaced. The world's newest nation is third in the number of refugees, after Syria and Afghanistan.
