Dialogue Over Division

Amid growing global tensions and polarization, human fraternity is increasingly recognized not only as a moral ideal but as a practical foundation for peace and human rights. The International Day of Human Fraternity (4 February) highlights our shared humanity across cultures and beliefs, affirming that all people are equal in dignity and that societies are stronger when respect prevails over suspicion. This year’s theme calls for dialogue over division, encouraging careful listening, responsible speech, and recognition of each other’s humanity, especially in difficult or uncertain times.

A decade of action against antisemitism

Decades after the Holocaust, antisemitism is rising in Europe and beyond, making education crucial for understanding violent pasts and preventing future atrocities. As Holocaust survivors dwindle, UNESCO is dedicated to advancing Holocaust education through its International Programme on Holocaust Education. Since 2015, it has reached 31 countries, developing teacher training resources and new curricula. Recently, UNESCO organized policy training at Auschwitz-Birkenau for senior policymakers. UNESCO also fights Holocaust denial through its partnership with the World Jewish Congress, providing factual resources, including the AboutHolocaust.org website, and has published guides to help educators counter denial while teaching about the genocide.

A recipe for change: Schools urged to promote healthy eating

Healthy food in schools is crucial for children’s lifelong dietary habits. According to the World Health Organization (WHO) new guidelines, and with childhood obesity rising and undernutrition persisting, schools play a key role in addressing this double burden. In 2025, 188 million school-aged children were living with obesity. WHO recommends setting standards to promote healthy foods while limiting unhealthy options and implementing nudging interventions to encourage better choices. Effective policies and enforcement are essential, yet only 48 countries have restrictions on marketing unhealthy foods. Prioritizing nutrition in schools is vital for future health and well-being.

Inside the Hagadera Refugee Camp in Dadaab, Kenya, Mariam has cultivated a thriving kitchen garden over the past 19 years, following her arrival from Somalia due to political unrest. Supported by the EU-funded Refugee Settlement Project and the Food and Agriculture Organization of the United Nations (FAO), her garden produces nutritious crops like spinach, kale, and jute mallow, surpassing others in quantity and quality. Fellow community members frequently visit to admire her garden and learn from her. The project aims to expand support to another 2,000 households, promoting vegetable gardening and backyard chicken rearing to improve nutrition and dietary diversity for families in the camp.

What we do

Due to the powers vested in its Charter and its unique international character, the United Nations can take action on the issues confronting humanity in the 21st century, including:

A UNIFIL peacekeeper from Spain on a regular patrol in the vicinity of Al Wazzani, south-eastern Lebanon as the sun sets in the horizon. Since 1948, more than a million women and men have served as UN peacekeepers.

Maintain International Peace and Security

The United Nations came into being in 1945, following the devastation of the Second World War, with one central mission: the maintenance of international peace and security. The UN does this by working to prevent conflict; helping parties in conflict make peace; peacekeeping; and creating the conditions to allow peace to hold and flourish. These activities often overlap and should reinforce one another, to be effective. The UN Security Council has the primary responsibility for international peace and security. The General Assembly and the Secretary-General play major, important, and complementary roles, along with other UN offices and bodies.

Protect Human Rights

The term “human rights” was mentioned seven times in the UN's founding Charter, making the promotion and protection of human rights a key purpose and guiding principle of the Organization.  In 1948, the Universal Declaration of Human Rights brought human rights into the realm of international law.  Since then, the Organization has diligently protected human rights through legal instruments and on-the-ground activities.

Deliver Humanitarian Aid

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.

Promote Sustainable Development

From the start in 1945, one of the main priorities of the United Nations was to “achieve international co-operation in solving international problems of an economic, social, cultural, or humanitarian character and in promoting and encouraging respect for human rights and for fundamental freedoms for all without distinction as to race, sex, language, or religion.”  Improving people’s well-being continues to be one of the main focuses of the UN. The global understanding of development has changed over the years, and countries now have agreed that sustainable development offers the best path forward for improving the lives of people everywhere.

Uphold International Law

The UN Charter, in its Preamble, set an objective: "to establish conditions under which justice and respect for the obligations arising from treaties and other sources of international law can be maintained."  Ever since, the development of, and respect for international law has been a key part of the work of the Organization.  This work is carried out in many ways - by courts, tribunals, multilateral treaties - and by the Security Council, which can approve peacekeeping missions, impose sanctions, or authorize the use of force when there is a threat to international peace and security, if it deems this necessary.  These powers are given to it by the UN Charter, which is considered an international treaty.  As such, it is an instrument of international law, and UN Member States are bound by it.  The UN Charter codifies the major principles of international relations, from sovereign equality of States to the prohibition of the use of force in international relations.

Structure of the
United Nations

The main parts of the UN structure are the General Assembly, the
Security Council, the Economic and Social Council, the Trusteeship Council, the International Court of Justice, and the UN Secretariat. All were established in 1945 when the UN was founded.

General Assembly

The General Assembly is the main deliberative, policymaking and representative organ of the UN. All 193 Member States of the UN are represented in the General Assembly, making it the only UN body with universal representation.

Security Council

The Security Council has primary responsibility, under the UN Charter, for the maintenance of international peace and security. It has 15 Members (5 permanent and 10 non-permanent members). Each Member has one vote. Under the Charter, all Member States are obligated to comply with Council decisions.

Economic and Social Council

The Economic and Social Council is the principal body for coordination, policy review, policy dialogue and recommendations on economic, social and environmental issues, as well as implementation of internationally agreed development goals.

Trusteeship Council

The Trusteeship Council was established in 1945 by the UN Charter, under Chapter XIII, to provide international supervision for 11 Trust Territories that had been placed under the administration of seven Member States, and ensure that adequate steps were taken to prepare the Territories for self-government and independence.

International Court of Justice

The International Court of Justice is the principal judicial organ of the United Nations. Its seat is at the Peace Palace in the Hague (Netherlands). It is the only one of the six principal organs of the United Nations not located in New York (United States of America).

Secretariat

The Secretariat comprises the Secretary-General and tens of thousands of international UN staff members who carry out the day-to-day work of the UN as mandated by the General Assembly and the Organization's other principal organs.

Gender Equality

Women and girls represent half of the world’s population and, therefore, also half of its potential. Gender equality, besides being a fundamental human right, is essential to achieve peaceful societies, with full human potential and sustainable development.

Ending Poverty

While global poverty rates have been cut by more than half since 2000, one in ten people in developing regions still lives on less than US$1.90 a day — the internationally agreed poverty line, and millions of others live on slightly more than this daily amount.

Interview with the youngest senior appointment in the history of the UN: Felipe Paullier (AAN S12-E7)

“Leaving young people at the sidelines of how we find solutions is not the way. It's really bringing them [in], because on many of the things, the solutions will come from them.”

A medical doctor by training, Dr. Felipe Paullier is a passionate advocate for young people. Two years ago, aged just 32, his life took a new turn when he became the first-ever Assistant Secretary-General for Youth Affairs, the youngest senior appointment in the history of the United Nations.

“I've heard this from the Secretary General. You know, power, in essence, is not to be given, it's to be taken. ”

The UN Youth Office believes that positive change is rooted in empowering young people to meaningfully participate in decisions that impact their lives and futures. In this episode of Awake at Night, Felipe reflects on youth demands for peace and opportunity, on the stubborn barriers to change, and shares why he always prescribes reconnecting with nature as a cure for digital overwhelm.
