In late May 2025, Uganda’s military conducted a crucial air-drop of 600 metric tons of food aid to South Sudan’s Upper Nile state, specifically targeting the violence-ravaged counties of Ulang and Nasir. This intervention came at the request of South Sudanese authorities and international partners, aiming to reach thousands of civilians displaced by intense fighting between government forces and armed militias. While this emergency relief is vital to saving lives, it also starkly reveals the depth of the crisis gripping the region—a crisis rooted in decades of political instability, ethnic tensions, and failed peace processes.
The air-drop operation underscores the extreme difficulty of delivering humanitarian aid in Upper Nile. Roads are either blocked by ongoing clashes or rendered impassable by seasonal rains, forcing reliance on costly and logistically complex aerial deliveries. This situation highlights not only the immediate suffering of civilians but also the broader failure of political and military actors to create conditions conducive to peace and security.
The Roots of Violence in Upper Nile
The conflict in Upper Nile state is part of South Sudan’s wider and deeply entrenched civil war, which erupted in December 2013 following political power struggles between President Salva Kiir and his former deputy Riek Machar. While initially framed as a political dispute, the war quickly became an ethnic and clan-based conflict, primarily between the Dinka and Nuer communities. Over time, the violence evolved into a fragmented and localized struggle involving numerous militias and armed groups, often motivated by control over land, cattle, and resources rather than purely political objectives.
Upper Nile, a strategically important and resource-rich region, has been a major battleground. The area’s diverse ethnic composition and history of intercommunal tensions have been exacerbated by the civil war. The White Army, a loosely organized Nuer youth militia originally formed for community defense and cattle protection, has played a significant role in the recent violence. Although the White Army operates independently of formal political control, it has been involved in fierce clashes with government forces and allied militias.
The recent surge in violence, including the February 2025 attack by the White Army on government barracks in Nasir, has led to retaliatory airstrikes by the South Sudan People’s Defense Forces (SSPDF), often targeting civilian areas. These attacks have caused significant casualties and mass displacement, with tens of thousands fleeing to forests and neighboring areas, many facing famine-like conditions.
The Human Cost: Displacement and Famine
The humanitarian consequences of the conflict in Upper Nile are devastating. The fighting has uprooted over one million people in the region alone, forcing them to abandon their homes, farms, and livelihoods. Displacement camps and makeshift settlements are overcrowded and lack basic services such as clean water, sanitation, and healthcare. Food insecurity has reached alarming levels, with many families surviving on drastically reduced rations or relying entirely on emergency aid.
The destruction of farmland and disruption of planting cycles due to insecurity have compounded food shortages. Markets have collapsed, and trade routes remain unsafe, further limiting access to food and essential goods. The reliance on air-dropped food aid, while lifesaving, is a stark reminder of the failure to secure safe passage for humanitarian convoys and the enormity of the crisis.
Children and vulnerable groups are particularly at risk. Malnutrition rates have soared, and health facilities are overwhelmed or inaccessible. The psychological trauma of violence and displacement—especially for children who have witnessed or been forcibly recruited into armed groups—adds another layer of suffering that will have long-term consequences for the region’s recovery.
Breakdown of Peace Agreements and Political Deadlock
The resurgence of violence in Upper Nile also reflects the broader collapse of South Sudan’s fragile peace architecture. The 2018 revitalized peace agreement, which aimed to end years of civil war by forming a coalition government and unifying armed forces, has faltered. Key provisions such as security sector reform, disarmament, and integration of rival militias have not been fully implemented.
Political mistrust remains high between President Kiir’s government and opposition leaders, including Riek Machar. The recent arrest of opposition figures, house arrest of Machar, and the deployment of Ugandan troops at the government’s invitation have further polarized the political landscape. Opposition groups have suspended participation in peace talks, and ethnic divisions are deepening, fueled by misinformation and hate speech.
This political deadlock undermines efforts to stabilize the country and creates a fertile ground for localized violence to escalate. The failure to address grievances related to land, cattle raiding, and political exclusion continues to drive cycles of revenge and militia mobilization.
Challenges to Humanitarian Access and Protection
The security environment in Upper Nile severely restricts humanitarian operations. Armed groups and, at times, government forces have obstructed aid deliveries through direct attacks, checkpoints, and bureaucratic barriers. Humanitarian workers face threats, looting, and violence, which jeopardizes their safety and limits the scale of assistance.
The need for air-dropped aid illustrates the extreme difficulties in reaching vulnerable populations by land. While air-drops provide critical relief, they are expensive, logistically complex, and cannot fully meet the needs of all affected communities. Furthermore, the risk of aid diversion by armed groups remains a concern, complicating efforts to ensure that assistance reaches those most in need.
Protection of civilians remains a major challenge. Indiscriminate attacks, including aerial bombardments on populated areas, have resulted in civilian casualties and widespread trauma. Reports of child recruitment into armed groups add to the gravity of the situation, threatening the future stability of the region.
Regional Implications and Uganda’s Role
Uganda’s military intervention and humanitarian support reflect the regional dimension of South Sudan’s conflict. Uganda has deployed troops to support the government’s efforts to stabilize Juba and surrounding areas, while also facilitating emergency aid deliveries to conflict zones like Upper Nile.
While this involvement has helped secure some areas, it has also been met with suspicion and opposition from rebel groups and local communities. The presence of foreign troops risks inflaming nationalist sentiments and could complicate efforts toward a negotiated settlement if not carefully managed.
Regional actors, including the Intergovernmental Authority on Development (IGAD) and the African Union, play a critical role in mediating peace and supporting humanitarian efforts. However, sustained political will and coordinated action are needed to prevent further deterioration.
The Path Forward: Beyond Emergency Aid
The air-drop of food aid by Uganda is a vital short-term response to an urgent crisis, but it cannot substitute for lasting solutions. Ending the violence and addressing the root causes of conflict—ethnic divisions, competition over resources, political exclusion, and weak governance—are essential for durable peace.
A comprehensive approach is needed that combines security sector reform, inclusive political dialogue, community reconciliation, and development programs aimed at rebuilding livelihoods and infrastructure. Ensuring humanitarian access and protecting civilians must remain priorities.
International partners should increase support for peacebuilding initiatives and hold all parties accountable for violations of ceasefires and attacks on civilians. Efforts to demobilize armed youth, prevent child recruitment, and provide psychosocial support to affected populations will be critical for healing and recovery.
The situation in South Sudan’s Upper Nile state is a tragic reminder of the human cost of unresolved conflict and political failure. The recent humanitarian air-drops by Uganda provide a lifeline to thousands but also highlight the immense challenges that remain. Without urgent action to restore peace, protect civilians, and foster inclusive governance, the cycle of violence and suffering will continue, undermining the hopes for a stable and prosperous South Sudan.
