Peace and Security

To save succeeding generations from the scourge of war

The United Nations has designated 8 and 9 May as a time of remembrance and reconciliation, to honour the memory of the millions who lost their lives during the Second World War and to reflect on their profound sacrifices. This year marks the 80th anniversary of the UN’s founding—an enduring testament to the international community's commitment to peace, dignity, and cooperation. Since its inception, the UN has played a central role in promoting the peaceful resolution of disputes and maintaining international peace and security, which remain among the Organization’s core pillars.

Risking his life to unearth the truth

Manuel Calloquispe Flores, a journalist for 15 years, has extensively investigated illegal gold mining in La Pampa, Peru, where criminal gangs exploit the region's biodiversity. Despite mining being prohibited due to its environmental impact, the area faces severe deforestation and mercury pollution. Calloquispe raises awareness about disappearances linked to mining and advocates for affected families, transitioning from business studies to journalism upon witnessing the mining crisis. Despite facing multiple assaults and death threats, he continues to report on these issues. Since 2022, UN Human Rights Peru has supported him, documenting numerous attacks against journalists and ensuring his safety through protective measures. His work highlights the significant dangers journalists face when exposing crime and environmental issues.

Afghan refugees forced to return face uncertain future

The Torkham border between Pakistan and Afghanistan has seen a surge of Afghan families returning home, driven by Pakistan’s Illegal Foreigners Repatriation Plan. In April, around 144,000 Afghans returned, including nearly 30,000 deported individuals. Many, like Ezatullah and his seven children, arrived with few belongings and uncertain futures, having lived in Pakistan for decades. With rising unemployment and poverty in Afghanistan, Ezatullah worries about providing for his family, emphasizing the importance of education for his children. Meanwhile, deportations are also occurring in Iran. The UN Refugee Agency (UNHCR) is offering emergency assistance, urging for $71 million in support to aid returnees, particularly women and children, as funding cuts severely limit their capacity to help those in need.

Turning over a new leaf

Forests cover nearly one-third of the Earth's land, offering vital benefits such as soil and water protection, climate regulation, and biodiversity preservation. They provide essential materials like wood and fibers, as well as food and medicine, which support millions of livelihoods globally. The resilience and adaptability of forests and trees largely stem from their genetic diversity. But what makes forests and trees resilient and adaptable? The answer lies in their genetic diversity. The Second Report on the State of the World’s Forest Genetic Resources highlights the urgent need to conserve and sustainably utilize these genetic resources. This is crucial for addressing challenges like deforestation, climate change, and poverty. By advancing research, improving policies, and fostering global cooperation, we can protect forest genetic diversity, ensuring that forests continue to thrive and serve future generations.

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.

Midwives in the DRC: “I saved four lives in one night”

Loti Kubuya Mielor, a midwife supervisor in Goma, Democratic Republic of Congo, vividly recalls a critical moment on January 2, 2023, when a woman gave birth to quadruplets under his supervision and subsequently experienced severe postpartum hemorrhage. Thanks to Loti's decisive actions and swift administration of medication within seven minutes, he stabilized the mother, preventing a life-threatening situation. Two years later, he still carries photos of the quadruplets on his phone. Midwives play an essential role in crises, often being the first and only care providers for pregnant women and newborns facing complications. In conflict-affected regions like eastern DRC, maternal and neonatal mortality risks can double due to disrupted health systems and limited access to vital services.

Stories of strength in Yemen

“My life has stabilized and I’m optimistic about the future,” says Arwa. A single mother displaced by conflict in Yemen, Arwa started a small business thanks to a cash grant. She is one of 8 million people in Yemen who received life-saving support last year from around 200 humanitarian organizations – many of them local Yemeni partners. In a country devastated by years of conflict, economic collapse and climate disasters, glimpses of hope still break through. From a mother restoring her child’s health to a family salvaging their home after floods, these are the stories of seven people in Yemen whose hope was restored by humanitarian assistance.
