When Mother Earth sends us a message

From extreme heat and rising sea levels to biodiversity loss and pollution, Mother Earth is in danger and making a clear call to action - a need to shift to a more sustainable economy that works for both people and the planet. This International Mother Earth Day (22 April), let’s mobilize for the planet and all the life it supports. We can all take action to protect nature, tackle climate change and promote harmony with the Earth. Join us for our event focused on the vital connection between human well-being and the health of our planet, taking place from 10 AM to 6 PM New York time.

Our current anthropocentric approach leans towards short-term profit and economic growth rather than valuing Nature’s contributions to our overall quality of life. Let’s change it.

Amid surging hunger and hopes for peace, Sudanese mark grim war milestone

As Sudan enters its third year of war, hunger has reached catastrophic levels. Famine has been confirmed in 10 areas, and 17 others are at risk. Millions of people like Abu Sufian and his family are on the move, crowded into temporary shelters before fighting uproots them once again. In a nation where nearly half the population is hungry, the World Food Programme (WFP) assistance is sometimes the only barrier against starvation. Over 13 million people across Sudan have received WFP assistance over the two years since fighting erupted. But even as the WFP aims to scale up its support to reach seven million people a month by mid-year, it faces severe funding and access constraints. “Without immediate assistance, especially in famine or famine-risk areas, thousands of lives are at risk," says Makena Walker, WFP's Acting Country Director in Sudan.

Justice and accountability: woman, life, freedom protests

Maryam was forced to record a message for her parents while in detention, facing a mock execution for protesting against systemic discrimination against women and girls in Iran. Despite her fear, she expressed determination, saying she would die with purpose. Two and a half years after the protests began, women and girls in Iran still face severe persecution. A recent UN Human Rights report confirms that Iranian authorities are implementing new restrictions on their rights and intensifying crackdowns on supporters of the "Woman, Life, Freedom" movement. The report was recently presented to the Human Rights Council in Geneva.

Endemic grape varieties attract agri-tourists

Givi Chubinidze, a winemaker from Georgia's Imereti region, carries on his family's winemaking tradition, which has been passed down for generations. His ancestors cultivated indigenous grape varieties like tsitska, krakhuna, and adanasuri, and Givi named his wines Nanua after an ancestor who served as a royal wine-cellar keeper. Currently, he cultivates around 120 endemic grapevine varieties on his land to adapt to climate change, believing these grapes embody Georgia's cultural heritage. In 2024, Givi received a matching grant from the Food and Agriculture Organization (FAO) through the European Neighbourhood Program for Agriculture and Rural Development (ENPARD) to enhance his wine production by integrating modern food safety standards with traditional methods, aiding rural development and food safety in the region.

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.

No hospitals, no hope

Sudan is facing a devastating civil war that has lasted two years, leading to widespread violence, displacement, and a severe healthcare crisis. Up to 80% of health facilities in the hardest-hit areas are either barely operational or completely closed. The conflict has displaced millions and resulted in horrific atrocities, including systematic rape. With an estimated 91,000 women expected to give birth in the next three months, many lack safe access to healthcare. Over half of Sudan’s population, approximately 30.4 million people, will need assistance in 2025 due to ongoing attacks on facilities and significant funding shortages. The United Nations sexual and reproductive health agency (UNFPA) is working to support the few operational health facilities, providing essential services to women and girls amidst these challenging conditions.

A vision for a Viet Nam park unites people and cranes

In 1988, Tram Chim National Park in the Dong Thap province of Viet Nam was home to a stunning sunset view featuring over 1,000 sarus cranes, the world’s tallest flying bird and a symbol of Dong Thap's natural and cultural heritage. However, due to the loss of key plant species, these cranes have not been seen in nearly 40 years, with none returning by 2022. The Biodiversity and Ecosystem Services Network (BES-Net), a UNDP flagship initiative supported by the German Government, is working with the Vietnamese Government to address this issue. They are implementing a strategy to restore wetland habitats and support local communities in Tram Chim, aiming to reduce ecosystem pressures and encourage the return of the cranes.
