Sudan's war between the Sudanese Armed Forces and the Rapid Support Forces, now grinding through its third year, has produced one of the most severe humanitarian crises on earth. The estimated death toll ranges from 40,000 to 250,000 — a gap that itself tells you how little visibility exists inside the country. More than 12.4 million people have been displaced. Neither side controls the whole country: the SAF holds the north and center including Khartoum, the RSF dominates Darfur and parts of the south. The stalemate guarantees continued fighting. The food numbers are staggering. Action Against Hunger reports 24.6 million people experiencing high levels of acute food insecurity. An estimated 825,000 children under five face severe acute malnutrition in 2026. The Famine Early Warning Systems Network has classified several areas — including displaced-person camps in Greater Darfur and Greater Kordofan — at IPC Phase 5, the most severe category. In Tawila displacement camp alone, a population larger than Frankfurt depends on a single hospital capable of performing C-sections. Climate shocks are layering on top of the combat damage. Extreme heat has caused power cuts of up to 12 hours daily. Drought has left riverbeds and fields barren across roughly half the country, while heavy rains and localized flooding have worsened conditions in other areas. The RSF's scorched-earth tactics compound the environmental destruction, leaving farmland doubly ruined by war and weather. The supply chain picture is arguably the most underreported dimension. Sudan depends on imported fertilizer and diesel shipped through the Strait of Hormuz and Bab el-Mandeb. Iran's blockade of Hormuz and Houthi disruption of Bab el-Mandeb have collapsed fertilizer supply from 450,000 metric tons to roughly 50,000 — an 89% drop. Diesel shortages make agricultural equipment inoperable and drive up transportation costs for whatever humanitarian goods do arrive. The International Food Policy Research Institute warned in October that staple food and fuel prices in Sudan rose sharply in September 2026. The international response is failing by its own metrics. The 2026 Humanitarian Response Plan calls for $2.9 billion but is just 41% funded, with $1.2 billion received. Meanwhile, the UN Security Council extended the existing arms embargo only on Darfur through December 11, 2026, declining to expand it nationwide. A nationwide embargo would have targeted drones — now the leading cause of civilian casualties in Sudan. Sudan's UN representative opposed expansion, arguing it would disproportionately limit the SAF, since the RSF sources weapons through trafficking networks, private military contractors, and regional traders that a formal embargo cannot easily reach. The foreign backer architecture sustains the war. Egypt, Turkey, Russia, and Iran officially support the SAF. The UAE is alleged to back the RSF — a claim Abu Dhabi denies. Without cutting these supply lines, no ceasefire holds. The Darfur-only embargo is a diplomatic fig leaf: it constrains the formal military more than the irregular one, creating a perverse incentive structure that rewards the faction operating outside international norms. Every system that could break the cycle — food supply, energy supply, diplomatic pressure, humanitarian funding — is simultaneously degraded. Climate shocks destroy the agricultural base, the Iran-Hormuz crisis chokes imported inputs, the arms embargo is too narrow to alter the military balance, and donor fatigue leaves the aid budget 59% short. Sudan is not experiencing a single crisis but a compounding extraction machine where war, climate, geopolitics, and institutional failure each amplify the others.
