More than one million Sudanese refugees in Chad faced acute funding shortfalls as of April 2026, with food, water, and shelter assistance at risk for the largest refugee population eastern Chad has ever absorbed, according to UNHCR.

The scale of displacement behind that figure is staggering. Since April 2023, more than 900,000 Sudanese refugees have crossed into eastern Chad, fleeing a war between the Sudanese Armed Forces and the Rapid Support Forces that erupted that month. By the end of February 2026, Chad was hosting 1.3 million Sudanese refugees, concentrated in eastern provinces including Ennedi Est and Wadi Fira, per UNHCR data. Camps like Iridimi have evolved from temporary way stations into long-term settlements, housing communities who did not anticipate staying for years. A resurgence of violence in Darfur in April 2026 alone displaced more than 100,000 additional people, pushing Chad's already stretched system further past its limits.

The humanitarian catastrophe driving this exodus shows no sign of easing. Nearly 25 million people — half of Sudan's population — face extreme hunger in 2026, a figure that has climbed continuously since fighting began. UN agencies identify nearly 20 million people in acute hunger as of May 2026, with more than 800,000 children at risk of severe acute malnutrition this year alone. Famine — a formal classification requiring evidence of widespread starvation and mortality — has been declared in one area and is considered a credible threat in 14 others; five zones in North Darfur, including el-Fasher, were projected to reach famine conditions within six months as of late 2024.

El-Fasher, the Sudanese army's last major stronghold in western Darfur, remains under siege with hundreds of thousands of civilians trapped and food deliveries severely disrupted, as Reuters reported in August 2025. Satellite and ground investigations had previously identified 14 rapidly expanding graveyards across Darfur as direct evidence of hunger and disease mortality. Desperate civilians have resorted to eating soil and leaves. Both the Sudanese Armed Forces and the Rapid Support Forces have been documented blocking food aid delivery, weaponizing hunger in a conflict that has displaced more than 14 million people total.

The Regional Containment Problem

Chad's capacity to shelter this influx faces structural constraints that long predate this crisis. The country ranks among the world's poorest, depends heavily on foreign aid, and now hosts a refugee population equivalent to that of some independent nations. Chad closed its border with Sudan in February 2026 after armed fighters crossed into its territory, a decision that cuts off a critical escape route even as violence in Darfur continues. The closure reflects a legitimate security concern from Chad's government in N'Djamena, but it leaves those fleeing after the shutdown with no legal way out.

The humanitarian funding system cannot keep pace with the need. A UN agency launched a $1.6 billion appeal for Sudan in February 2026, while UNHCR separately requires $928.9 million for the full Sudan emergency across the region. With roughly 4.3 million Sudanese refugees scattered across neighboring countries — concentrated in Egypt and eastern Chad — the per-capita funding gap remains substantial. The World Food Programme (WFP) has operated in Chad since 1968, providing established logistics networks that would normally enable rapid response, but infrastructure means little when core funding lines go unfilled.

Donor commitment to Sudan's emergency has proved uneven. The Sudan conflict competes poorly for Western attention alongside Ukraine, Gaza, and other concurrent humanitarian emergencies. IPC famine declarations — which carry significant technical and diplomatic weight in triggering emergency funds — have historically unlocked some additional financing, but the gap between declared need and committed resources has widened rather than narrowed over the past two years.

What is unfolding in eastern Chad — families sheltering under trees, children developing acute malnutrition — reflects a predictable downstream consequence of a war that has seen no meaningful ceasefire, no sustained diplomatic process, and no mechanism to enforce aid access or punish those obstructing deliveries. The 1.3 million refugees now in Chad are not a temporary population; they are settling in for the long term. Without either a shift in the conflict itself or a substantial increase in funding, the humanitarian system is managing a protracted emergency on emergency-response budgets. That structural mismatch will not resolve itself.
