SITUATION OVERVIEW

• As of 31 October, flooding has affected an estimated 1,024,500 people in 29 counties across six states, with Jonglei and Unity accounting for nearly 87 per cent of those impacted. Nearly 355,000 people have been displaced in 18 counties, with many moving to higher ground. Of those affected, an estimated 631,789 people are in Jonglei State, 256,102 people in Unity State, 85,789 people in Upper Nile State, 24,505 people in Central Equatoria State, 15,780 people in Western Equatoria State and 10,578 people in Warrap State.
• Widespread damage has been reported to homes, farmland and infrastructure. Schools and health facilities have been destroyed, resulting in the loss of essential supplies and preventing the resumption of education and health services. Crop fields have been inundated, devastating harvests, while livestock pasture has been washed away or remains waterlogged, increasing food insecurity in affected areas. While floodwater has begun to recede in some areas and families are returning home, many find their houses destroyed, basic services unavailable, and livelihoods lost. Fishing kits and livestock retreatment are needed to restore livelihoods. Urgent need for tarpaulins, blankets, mosquito nets, and cooking utensils is required. Vulnerable groups, especially women, children, and people with disabilities, face heightened risks of gender-based violence and exploitation. Safe spaces and psychosocial support are critical.
• A total of US$58 million is required to support approximately 870,000 flood-affected people across prioritized counties through the Food Security and Livelihoods Cluster. The funding will help restore livelihoods and provide essential assistance to vulnerable communities impacted by recent environmental shocks.
• Jonglei State
• Flooding continues to affect parts of Jonglei State, including Fangak, Ayod, Twic East, Duk, Canal/Pigi, and Akobo counties. In the Greater Pibor Administrative Area, Pibor and Pochalla towns are inundated. Humanitarian partners have conducted Initial Rapid Needs Assessments in Pibor, Gumuruk, and Likuangole and are mobilizing to respond. An inter-agency rapid needs assessment mission reports over 25,500 people were displaced by floods in Canal/Pigi County. Of those, 12,500 people are in Kurwai and 13,000 in Wunllet payam in urgent need of assistance. Most are displaced by conflict and flooding, with a high presence of women and children. Partners identified an acute malnutrition emergency among children under five and pregnant and lactating women. Stabilization centers are non-functional due to lack of nutrition supplies. Health facilities are critically under-resourced, lacking essential drugs and staff. Rising cases of diarrhea, malaria, and pneumonia have been reported. Severe overcrowding is prevalent, with multiple families sharing shelters or sleeping in open spaces.
• Upper Nile State
• On 27 October, the Commissioner of Baliet County reports that rising Nile River water levels have swept through large areas along the riverbanks and destroyed more than 1,000 acres of farmland. Authorities in Fashoda County report severe flooding affecting over 8,000 people (1,200 households). Access to some areas remains challenging due to rising water levels, and local leaders are appealing for scaled-up emergency interventions from national authorities and humanitarian partners. No heavy rains were recorded in Renk County this week; however, rising river levels continue to increase flood risk in Renk Town. Authorities are calling on partners with available capacity to support dyke construction to mitigate the threat.
