We have the biggest humanitarian crisis on the planet in Sudan, the biggest hunger crisis, the biggest displacement crisis… and the world is giving it a shrug,” he said in an interview from neighbouring Chad after a visit to Sudan this week.

The United Nations says that nearly 26 million people inside Sudan are suffering acute hunger. “I met women barely surviving, eating one meal of boiled leaves a day,” Egeland said.

One of few organisations to have maintained operations in Sudan, the NRC says some 1.5 million people are “on the edge of famine”. “The violence is tearing apart communities much faster than we can come in with aid,” Egeland said. “As we struggle to keep up, our current resources are merely delaying deaths instead of preventing them.”

Two decades ago, allegations of genocide brought world attention to Sudan’s vast western region of Darfur where the then government in Khartoum unleashed Arab tribal militias against non-Arab minorities suspected of supporting a rebellion. “It is beyond belief that we have a fraction of the interest now for Sudan’s crisis than we had 20 years ago for Darfur, when the crisis was actually much smaller,” Egeland said.

He said Israel’s wars in Gaza and Lebanon and Russia’s war with Ukraine had been allowed to overshadow the conflict in Sudan. But he said he detected a shift in the “international mood”, away from the kind of celebrity-driven campaigns that brought Hollywood star George Clooney to Darfur in the 2000s. “More nationalistic tendencies, more inward-looking,” he said of Western governments led by politicians compelled to “put my nation first, me first, not humanity first.”

According to the UN, both sides are using hunger as a weapon of war. Authorities routinely impede access with bureaucratic hurdles, while paramilitary fighters have threatened and attacked aid workers. “The ongoing starvation is a man-made tragedy… Each delay, every blocked truck, every authorisation delayed is a death sentence for families who can’t wait another day for food, water and shelter,” Egeland said.
