One of the purposes of the United Nations, as stated in its Charter, is "to achieve international co-operation in solving international problems of an economic, social, cultural, or humanitarian character." The UN first did this in the aftermath of the Second World War on the devastated continent of Europe, which it helped to rebuild. The Organization is now relied upon by the international community to coordinate humanitarian relief operations due to natural and man-made disasters in areas beyond the relief capacity of national authorities alone.
In 2021, 235 million people will need humanitarian assistance and protection. This number has risen to 1 in 33 people worldwide - a significant increase from 1 in 45 at the launch of the Global Humanitarian Overview 2020, which was already the highest figure in decades. The UN and partner organizations aim to assist 160 million people most in need across 56 countries and will require a total of $35 billion to do so.
International days and weeks are occasions to educate the public on issues of concern, to mobilize political will and resources to address global problems, and to celebrate and reinforce achievements of humanity. The existence of international days predates the establishment of the United Nations, but the UN has embraced them as a powerful advocacy tool. We also mark other UN observances.
