Save our glaciers

Glaciers are melting faster than ever due to climate change. As our planet heats up, our frozen world is shrinking, making the water cycle unpredictable. For billions of people, meltwater flows are changing, causing floods, droughts, landslides and sea level rise. Protecting glaciers is essential for survival. This World Water Day (22 March), be part of the global ‘Glacier Preservation’ campaign. Everyone – from individuals to governments – must help reduce global warming and adapt to shrinking glaciers. Join our events and watch the celebration!

What we gain by choosing equality for women and girls

It’s been 30 years since the Beijing Declaration and Platform for Action established a global roadmap for advancing the rights of women and girls. Despite some progress, economic inequalities remain deeply entrenched in societies, exacerbating issues like domestic violence. Insufficient social protections, such as paid parental leave and childcare, along with higher tax rates for female earners, negatively impact women’s lives. The UNDP's Gender Equality Seal for Public Institutions is a voluntary program in over 100 institutions across 30 countries, aimed at enhancing policy reforms to better address the diverse needs of women.

Abolition of the death penalty is gaining momentum worldwide

The death penalty has no place in the 21st century, affirms the UN Human Rights Chief Volker Türk citing its contribution to wrongful executions. Speaking at the Human Rights Council panel in Geneva, he highlighted the Global South's leadership in the movement to abolish capital punishment, driven by legal reforms and judicial interventions. Despite this progress, 2023 saw a 31% increase in executions, with 1,153 recorded in sixteen countries, primarily in Iran, Saudi Arabia, Somalia, and the U.S. Türk noted that over 40% of executions were for drug-related offenses, mostly in Iran. He stressed the judiciary's critical role in interpreting the law to favor abolition, referencing Malawi's and Malaysia's recent reforms.

Breaking boundaries in hot pepper production in Jamaica

Alex Sybron, 33, transitioned from a budding cricket career to becoming the Chief Plant Breeding Officer at Jamaica's Bodles Research Station, focusing on improving seed quality for the agricultural sector. Encouraged by his mother to pursue education after a potential injury, he discovered a passion for plants. Collaborating with the Food and Agriculture Organization of the United Nations (FAO), Sybron’s team works to ensure disease- and pest-free seeds, which are vital for enhancing crop productivity. Jamaican hot peppers, known for their unique heat and flavor, are a primary export, but issues like low seed quality and poor planting practices challenge production. Training sessions for farmers emphasize best practices to improve yield and combat plant diseases.

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.

Rohingya children face an emergency within an emergency

Seven years after hundreds of thousands of Rohingya fled horrific violence and persecution in Myanmar, refugee children and their families are still living in the sprawling, overcrowded camps. With little to no opportunity to earn a livelihood, families living in the camps rely almost entirely on humanitarian assistance. As a result, Rohingya living in the camps have limited access to diverse and nutrient-rich foods. A combination of an unusually long monsoon season in 2024, further displacement, intermittent reductions in food rations, and now a global aid funding crisis have contributed to a deepening malnutrition crisis that saw a 27 per cent spike in severe acute malnutrition cases in February 2025 compared with a year earlier.

How forests support the future of food

Forests are vital for biodiversity, climate regulation, and agriculture. They help maintain soil fertility, regulate water cycles, and support biodiversity, which are essential for productive farming. Sustainable practices like agroforestry and crop rotation can reduce deforestation and land degradation. However, the growing demand for food can lead to unsustainable farming practices that harm forests. This interdependence underscores the importance of balancing forest conservation, food production, and ecosystem health for long-term sustainability. Addressing these connections is key to combating climate change, ensuring food security, and protecting forests. Innovative projects can help maintain this balance. On the occasion of the International Day of Forests (21 March) here are three examples of how food products and forests intersect to promote sustainable land use and community benefits worldwide.
