The United Nations has announced sweeping cuts to its global humanitarian operations, blaming what it described as the “deepest funding cuts ever” for a drastic scaling back of its aid ambitions.

In a statement released on Monday, the UN Office for the Coordination of Humanitarian Affairs (OCHA) said it was now appealing for $29bn in aid – down sharply from the $44bn it had requested in December – and would refocus on the most critical emergencies under a “hyper-prioritised” plan.

The move follows a steep decline in funding from key donors, with the United States – historically the largest contributor – having slashed foreign aid under the administration of President Donald Trump.

Other donors have since followed suit, citing global economic uncertainty. So far this year, the UN has received only $5.6bn, a mere 13 percent of what it initially sought.

This comes as humanitarian needs soar in conflict zones, including Sudan, Gaza, the Democratic Republic of the Congo (DRC) and Myanmar.

“Brutal funding cuts leave us with brutal choices,” said undersecretary-general for humanitarian affairs and emergency relief coordinator, Tom Fletcher.

“All we ask is 1 percent of what you spent last year on war. But this isn’t just an appeal for money – it’s a call for global responsibility, for human solidarity, for a commitment to end the suffering,” he added.

OCHA said remaining aid efforts would be redirected towards the most urgent crises and aligned with planning already under way for 2025 to ensure maximum impact with limited funds.

“We have been forced into a triage of human survival,” Fletcher said. “The math is cruel, and the consequences are heartbreaking. Too many people will not get the support they need, but we will save as many lives as we can with the resources we are given.”
