South Sudan is facing a catastrophic humanitarian crisis driven by nearly four years of a brutal civil war.
Right now six million people - half the population - are facing extreme hunger, and over 60 per cent of the population is in need of humanitarian assistance.
Civilians have been attacked, and schools and hospitals have been looted and burned. Tens of thousands of people have been killed. The fighting has forced nearly four million people - one in three - from their homes. As they flee, people lose their possessions, crops and income, and often get stranded in places where there aren't enough facilities to support tens of thousands of new arrivals. Most of them are women and children, who are particularly vulnerable to the risks that come with finding aid and services away from their communities.
Many also retreat to very isolated areas, keeping themselves far away from fighting, but also from aid.
Back in February, famine was declared in Leer and Mayendit, two counties of former Unity State; 100,000 people were facing famine, and one million more were on the brink.Since then Oxfam and other humanitarian organisations have raced to respond - aid has made a really important difference: we have helped prevent famine from spreading. But despite this, there are more people facing severe hunger in South Sudan now than ever before.
Over three million have now been forced from their homes, with 1.3 million people having fled to neighbouring countries and approaching two million displaced within the country.
The people of South Sudan are used to coping with adversity but in over 30 years of working in these affected areas, Oxfam has never witnessed such dire need. Civilians including women and children have been attacked, and schools and hospitals have been looted and burned. Tens of thousands of people have been killed.
