The Age of Longevity: Rethinking Systems for Longer Lives

People worldwide are living longer than ever before, but are those extra years healthy, dignified and fair? Under the theme "The Age of Longevity: Rethinking Systems for Longer Lives," the 2026 International Day of Older Persons calls on governments, civil society, the private sector, researchers and older persons to rethink how societies support longer lives.  The observance highlights the need to ensure that longer lives are also healthy, dignified and fair for all. Watch this year's celebration on UN Webtv.

The number of people aged 60 years or over has more than doubled, from around 541 million in 1995 to 1.22 billion in 2025 and is projected to reach 2.1 billion by 2050.

When seeking help means risking everything

For women who use drugs, asking for help can mean risking arrest or losing their children. A UN Human Rights report reveals how punitive drug policies expose women and girls to abuse, overlook coercion and poverty, and keep them from vital care. Pregnant women can face forced treatment or imprisonment, while mothers may be separated from their children. Globally, only one in 18 women with drug use disorders receives treatment. The report calls for health care that meets women’s needs, alternatives to imprisonment and an end to barriers that deter them from seeking help, with women’s lived experience helping shape policy.

From invisible to recognized

For families on Guinea-Bissau’s remote islands, registering a child can mean days of travel and costs they cannot afford. Mobile legal clinics helped register over 1,300 births in 2025, giving children a legal identity. Across Gaza, the West Bank and East Jerusalem, legal aid, mediation and psychosocial support reached almost 90,000 people, mostly women and children. Working in more than 100 countries and territories, the United Nations Development Programme helps communities access justice, protect their rights and build peace, with trusted local voices shaping solutions.

When El Niño brings drought, every minute counts

Cambodian farmer Sokhom Kha once faced drought without knowing what was coming. Now, forecasts give her time to protect her crops. With ten days’ warning that rain would not come, she stored water in her fields. She is among more than 4,000 farmers receiving advice through a project run by the Food and Agriculture Organization of the United Nations and Cambodia’s government, financed by the Green Climate Fund. As El Niño threatens harvests, early warnings and practical guidance help families manage scarce water, reduce losses and protect their livelihoods.

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.

When harvests fail, hunger follows

For families who depend on farm work to buy food, drought can wipe out both crops and wages. The World Food Programme warns that the 2026–27 El Niño could push 49 million people into acute hunger, with communities already facing food crises most exposed. Rising food and fuel prices compound the threat, while funding shortages limit assistance. To protect livelihoods before disaster strikes, the agency is preparing early action in about 51 countries, helping families safeguard food and water supplies and recover sooner.
