In August, widespread flooding and ongoing violence continued to exacerbate humanitarian needs across South Sudan. As of 31 August, an estimated 263,000 people were affected by floods across 11 counties in Jonglei, Unity, and Upper Nile states, with 95,000 people displaced to higher ground. Overcrowding at relocation sites has led to growing tensions among displaced families. At the same time, the increasing incidence of waterborne diseases and snake bites is heightening public health risks. The number of people affected is expected to rise further as heavy rains continue and assessments progress. In Jonglei State, a dyke breach on 30 August flooded Old Fangak Town, displacing residents and damaging homes, farmland, humanitarian compounds, and critical infrastructure. Humanitarian access remains constrained in many flooded areas already grappling with food insecurity, malnutrition, violence, and displacement. In Paguir Payam (Fangak County), nutrition screening of 364 children under five revealed a Global Acute Malnutrition (GAM) rate of 37 per cent, more than double the WHO emergency threshold. Conflict also persisted throughout August in Upper Nile, Jonglei, and Central Equatoria states, resulting in reports of civilian casualties, population displacement, and disruption of humanitarian services. In Morobo County (Central Equatoria), clashes between armed groups displaced approximately 24,000 people to Morobo Town and across borders into Uganda and the Democratic Republic of the Congo. Local authorities have reported the destruction of homes and public infrastructure during the fighting. From January to August, an estimated 397,000 people were newly displaced across South Sudan, with Upper Nile, Jonglei, and Central Equatoria recording the highest displacement figures. As of 31 August, 90,307 suspected cholera cases, including 1,552 deaths, have been reported across 55 counties in nine states and three Administrative Areas.
