Background

South Sudan remains a medium-intensity conflict zone, ranked 156 out of 163 in the 2025 Global Peace Index. Humanitarian needs are critical, with 75% population of 14.2 million people requiring some sort of assistance. The crisis is deepening due to prolonged conflict, poor infrastructure, severe food insecurity, fragile healthcare systems, widespread flooding, economic collapse, political uncertainty ahead of elections, and a spillover from the Sudan conflict, including disrupted oil exports and both returnee and refugee influxes. A major funding shortfall is further straining humanitarian operations. Logistics Gaps and Bottlenecks Humanitarian logistics in South Sudan continue to face significant challenges related to road access and the sustainability of access routes. The recent escalation in conflict has made it increasingly difficult to maintain consistent and reliable access to affected populations. These barriers frequently result in delivery delays and increased operational costs Road Access and Sustainable Access Challenges Although there have been some improvements brought about by initiatives from the United Nations and the private sector, the country’s road network remains underdeveloped. This infrastructure gap is particularly pronounced during the rainy season when many roads become largely impassable. The states of Jonglei, Unity, and Upper Nile are especially affected, with poor road conditions severely limiting the movement of humanitarian assistance and impeding the timely delivery of aid to vulnerable communities.
