The United Nations said Monday that it needed $46.4 billion next year to bring life-saving help to around 180 million people in desperate circumstances around the world.
The UN said the global humanitarian outlook for 2024 was "bleak", with conflicts, climate emergencies and collapsing economies "wreaking havoc" on the most vulnerable.
While global attention focuses on the conflict raging in the Gaza Strip, the UN said the wider Middle East, Sudan and Afghanistan were among the hotspots that also needed major international aid operations.
But the size of the annual appeal and the number of people it aims to reach were scaled back compared to 2023, following a decrease in donations.
"Humanitarians are saving lives, fighting hunger, protecting children, pushing back epidemics, and providing shelter and sanitation in many of the world's most inhumane contexts," UN aid chief Martin Griffiths said in a statement.
"But the necessary support from the international community is not keeping pace with the needs," he said.
With a few weeks left to go, 2023 is likely to be the first year since 2010 when humanitarian donations declined compared to the previous year.
