The crisis is expected to worsen further. In April, 7.5 million South Sudanese are predicted to suffer from acute famine, compared to 6 million today, according to Oxfam.
At the same time, the aid organization is sounding the alarm that aid to the country is insufficient. South Sudan has only received 40 percent of the planned $1.6 billion in aid needed, according to Oxfam, which points to Western countries cutting their aid budgets.
South Sudan became independent in 2011, making it the world's youngest country. Shortly after independence, a civil war broke out. The difficult situation has been exacerbated by the country also receiving a large number of refugees from war-torn neighboring Sudan.
Corruption is also a major problem, with high-ranking people enriching themselves from oil resources, as the UN has documented.
