The UN's new humanitarian chief describes the scale of the challenge that confronts him

In December, the UN released its annual review of the scale of worldwide need. In total, 305 million people need urgent humanitarian aid from Syria and sub-Saharan Africa to Myanmar, Venezuela and Ukraine. At the same time, 2024 was the deadliest year ever to be a humanitarian worker. Tom Fletcher took over the UN humanitarian affairs office in October. He says that while the task is daunting multilateral cooperation is essential to success.
