According to recent data, two-thirds of the country's population - about 7.74 million people - are likely to face famine between May and July this year, Mishak Malu, representative of the Food and Agriculture Organization (FAO) of the United Nations in South Sudan, said.
Mallo warned that 2.9 million people are likely to be approaching catastrophic levels of food insecurity during this period.
He indicated that 87,000 people are likely to face catastrophic food insecurity, this is the fifth phase of the official IPC, in parts of Jonglei in Bor Administrative District, as well as in parts of Lakes and Unity states.
Experts expected that about 1.34 million children and 676,000 pregnant and lactating women will suffer from malnutrition in 2022.
"This famine can only be addressed through urgent and sustained multi-sectoral humanitarian assistance," Malo said.
