Peace and Security

Choosing peace in a time of rising global threats

The world faces increasingly complex threats, from nuclear tensions to violations of the purposes and principles of the United Nations Charter. Born in 1945 “to save succeeding generations from the scourge of war”, the UN continues to lead efforts in conflict prevention, peacekeeping, and post-war recovery. As Secretary-General António Guterres reminds us: “If war is a choice, peace can be too. It is time for a recommitment to peace.” Let’s join forces to build a more peaceful future. Learn more about the UN’s role in advancing Peace and Security.

Grassroots partnership empowers South Africa’s youth

Kabelo Motlhophe never thought he would move from a cleaning job to a leadership role in local government. After witnessing a civic education workshop while cleaning, he became intrigued and decided to join the training sessions by Activate! Change Drivers, a youth empowerment network. This led him to run for election as a ward councillor in Mamelodi, where he won in 2021. Motlhophe credits the training, especially on public participation rights, as key to his success. Activate! partners with UN Human Rights Regional Office for Southern Africa to promote youth engagement in civic life and participation in public affairs.

The physician committed to creating a fairer world for migrants

When he began practicing medicine several years ago, Dr. Jürgen Adam Sánchez believed his role was to treat diseases. However, working closely with migrant children and adolescents, he quickly realized that the deepest pain is often not physical but rooted in the stories these young migrants carry with them along their journeys. Sánchez is a Mexican physician specializing in public health based in Hermosillo, Sonora. At 29, he has served as a shelter coordinator, university professor, and activist. Sánchez advocates for compassionate healthcare and believes in the potential of migrant youth to break cycles of violence, emphasizing the importance of strong peer support networks alongside access to services. He is committed to creating a fairer world for migrants.

“Madd de Casamance” helps Senegalese communities profit from a native fruit

For generations, communities in Senegal’s Casamance region have harvested wild madd fruit, prized for its richness in vitamins and antioxidants. Traditionally collected by youth and often found in the "Sacred Woods," madd is deeply tied to local customs. Despite its cultural significance, producers have faced challenges ranging from limited control over pricing to unsustainable harvesting, over-exploitation, and forest fires. However, on June 25, 2024, madd became the first Senegalese product registered as a Geographical Indication (GI), ensuring protection of its name and quality. This initiative promotes sustainable practices and strengthens local economies by keeping production and income within the community.

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:

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.

Why I’ll always champion Afghan women, with Georgette Gagnon (AAN S11-E3)

“You know, what am I doing every day for human beings, particularly those who are in, you know, a much more challenging situation, we need to support their courage, their resilience, their need to survive...and their rights.”

With her background in human rights law, Georgette Gagnon was once said to represent the conscience of war. Currently serving as the Secretary-General’s Deputy Special Representative for Afghanistan, she has been devastated by the sweeping loss of rights for women and girls there.

“You used to see across the country hundreds of girls going to school... Now, of course, you don't see that, and it's heartbreaking. It's such a huge loss for the entire society,” she says.

Afghanistan has one of the highest numbers of people in need of humanitarian support, and drastic cuts to humanitarian assistance affect access to critical care for millions. In this episode, Georgette Gagnon shares her hopes and fears for a country close to her heart, and reflects on a career serving in some of the world’s toughest places, from Syria to Sudan and Libya.

Shabib’s Ocean Promise

The ocean, covering over 70% of our planet, is vital for human existence but faces crises from pollution, overfishing, and climate change. Grassroots actions are essential, exemplified by Shabib Asghar, a PADI Dive Master and UNDP Youth4Climate awardee from Pakistan. After his first dive in 2015, he became Director of Marine conservation Pakistan and launched the Reef Revival Initiative in 2025, focusing on organic coral propagation without artificial structures. Leading a dedicated team, Shabib empowers youth through hands-on projects, promoting sustainable practices like eco-friendly fishing and habitat restoration to protect coastal ecosystems.
