South Sudan: Seasonal Flooding Snapshot, As of 21 October 2019

Originally published



Unusually heavy seasonal flooding is affecting large areas of South Sudan, with estimates that between 600,000 and 800,000 people have been affected, according to authorities. As of late October, Ayod, Maban, Mayom, Nyirol, Pibor and Uror in Greater Upper Nile were among the counties most heavily affected by the floods.

Based on assessments already conducted in affected areas, and in line with experience from previous floods in South Sudan, critical needs include access to safe drinking water, anti-malarial and other basic drugs, and plastic sheets to be used as temporary shelters for families with damaged or destroyed houses. The degradation or loss of crops and other sources of livelihoods can cause longer-term humanitarian needs and reduce food security in the following year. The scale of the impacts on the late-2019 harvest needs to be determined.

The high water level in some flooded areas is constraining vulnerable people’s physical access to basic services and restricting humanitarians’ ability to assess and respond to needs. In places where water level has receded, humanitarian organizations are responding to assessed needs, in support of the Government. Regular humanitarian response in line with the 2019 Humanitarian Response Plan is ongoing in flood-affected counties, and can be adjusted based on assessed priority needs. For example, based on early assessments, there could be a need to fast-track the next round of humanitarian food assistance in some locations. Humanitarian organizations continue to engage with the Government on the needs and the response.
