An estimated 86 percent of the more than 900,000 South Sudanese refugees in Uganda are women and children, says the UN.
Massive numbers have streamed in since the brutal civil war at home reignited last July. The flight from violence and chaos, often without time to plan, has left many families separated. Mothers and children run alone. Husbands and fathers are either staying behind to work, fighting, missing or presumed dead.
As a result, many women are leading their extended households and communities in Uganda's refugee settlements trying to build a life. They didn't plan it, but they now find themselves living in a woman's world.
