Women and girls around the world are calling for peace with messages like "Ceasefire" and "End the war." UN Women is amplifying these urgent demands through its initiatives. Research shows that when women participate in peace negotiations, the outcomes are more effective and enduring. Yet, 25 years since the launch of the Women, Peace, and Security agenda—where global leaders recognized the impact of war on women and committed to their participation in peace processes —governments are still falling short. Understanding the link between gender equality and peace is essential, especially given the risks of neglecting these critical areas.
Floods, cyclones, and wildfires devastate communities, but these disasters are shaped by human choices—where we build, how we farm, and what we invest in. Climate change amplifies these hazards, causing over 200ドル billion in annual damages and 2ドル.3 trillion in total costs. The human toll is immense: displaced families, lost livelihoods, and stalled development. Yet, many governments spend less than 1% of budgets on disaster risk reduction. The choice is clear: invest in resilience or keep paying for disasters.
About 673 million people face hunger, while obesity and food waste reveal a system out of balance. Conflicts, extreme weather, economic shocks, and inequality strain the land we farm, the water we depend on, and the biodiversity that supports life. This World Food Day (16 October) marks the FAO’s 80th anniversary and calls for global collaboration to build a peaceful, sustainable, and food-secure future where everyone can access a healthy diet and live in harmony with the planet.

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:
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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).
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.
The United Nations is the only place on Earth where all the world's nations come together to discuss common problems and find shared solutions that benefit all of humanity. Learn about the main areas of the UN’s activities; how it makes a difference to the world’s people; and how every citizen can get involved and make a contribution.

As the world’s only truly universal global organization, the United Nations has become the foremost forum to address issues that transcend national boundaries and cannot be resolved by any one country acting alone.

How climate information and early warning systems protect lives and economies
As climate change drives more extreme weather, early warning systems are vital to protect lives and economies. These systems rely on climate information—data from sensors and stations—transformed into insights for forecasts and planning. Despite their proven value, investment remains low. Yet early warnings can cut damage by 30% and yield up to 10x returns. In sectors like agriculture and energy, better climate services could unlock over 160ドルB annually in global economic gains.
Afghanistan trembles, then hungers, now freezes
In eastern Afghanistan’s Andalachakin village, Khair Rahman recounts the devastating late-August earthquake that destroyed his home and injured several family members. With winter approaching, he fears for their survival in harsh conditions. The 6.0 magnitude quake claimed over 2,000 lives and left thousands injured and homeless across four provinces. Many survivors are now living in makeshift shelters or sleeping under the stars. As they confront severe hunger, families like Rahman’s are faced with a dire lack of humanitarian assistance just as winter sets in, adding to their desperate situation. Learn more about WFP's work in Afghanistan.
