WFP South Sudan External Sitrep September 2025

SITUATION UPDATE
• South Sudan is facing overlapping crises, including violence, protracted economic decline and climate shocks, which continue to fuel food insecurity and malnutrition.
• Armed clashes between government and opposition forces in Upper Nile, Jonglei, and Central Equatoria states have displaced 397,000 people within and across borders since March 2025. The Upper Nile conflict has particularly displaced 204,000 people into Sudan, including 72,000 South Sudanese.
• About 9.3 million people require humanitarian assistance. The Integrated Food Security Phase Classification (IPC) update released in June 2025 revealed worsening acute food insecurity trends in areas affected by the clashes, including Ulang, Nasir and Fangak counties. About 7.7 million people were projected to be in IPC Phase 3 (Crisis) and above, with 83,000 in Phase 5 (Catastrophe) and 2.4 million people in IPC Phase 4 (Emergency). Nasir and Ulang counties were projected to be at risk of famine under a worst-case scenario. Acute malnutrition remains widespread, with Ulang, Nasir, Baliet and Rubkona counties in IPC acute malnutrition Phase 5 (Extremely Critical).
• The Sudan conflict has forced 1.2 million people into South Sudan, mostly South Sudanese returnees but also 400,000 Sudanese refugees. As of 30 September, South Sudan hosted 590,000 refugees, 95 percent of whom are Sudanese.
• South Sudan is facing severe flooding, which could affect up to 1.6 million people. As of 30 September, floods had affected 639,000 people across 26 counties in six states, with Jonglei and Unity states accounting for 87 percent of those affected. Floods have displaced 175,000 people, forcing them to move to higher grounds in 16 counties.

• South Sudan is grappling with the longest cholera crisis in its history. Since declaring the outbreak in September 2024, the country has reported 93,000 cases and 1,500 fatalities, with a case fatality rate of 1.7 percent across the country.

• Food prices remain high, eroding households’ access to food. Supported by relative exchange rate stability and the onset of seasonal harvests in some areas, the cost of a standard food basket decreased by 12 percent across monitored markets in September. However, the basket cost remained 650 percent above its pre-Sudan conflict level in April 2023.
