The Future of Peacekeeping

For nearly 80 years, UN peacekeepers have made tangible impact to communities in conflict zones—from Liberia and Namibia to Cambodia, Sierra Leone, and Timor-Leste—helping countries transition from conflict to lasting peace. Today, more than 68,000 civilians, military, and police personnel are deployed across 11 UN missions. Observed under the theme “The Future of Peacekeeping”, this year’s International Day of UN Peacekeepers (29 May) looks at the invaluable contributions peacekeepers have made and underscores the need to adapt peacekeeping to meet evolving global challenges. #PKDay

The observance honors the more than 4,400 peacekeepers who have lost their lives in the cause of peace, including 57 in 2024 alone.

How can we tackle climate misinformation and disinformation?

The fight against climate misinformation is a global effort involving governments, academia, media, and civil society. These actors engage in research, policy advocacy, education, and public outreach to combat misinformation that undermines climate understanding and action. The UN has launched the Global Principles for Information Integrity to promote healthy information spaces, and in November 2024, a Global Initiative for Information Integrity on Climate Change was established by Brazil, the UN, and UNESCO. However, most efforts are concentrated in the Global North, highlighting the need to empower Global South stakeholders to address climate misinformation.

Reparatory justice in the age of Artificial Intelligence

With calls for reparations for the historical legacies of enslavement and colonialism growing louder, this year's Permanent Forum on People of African Descent held a session titled "Africa and People of African Descent: United for reparatory justice in the age of artificial intelligence”. Participants emphasised that the injustices of colonialism and systemic racism continue to affect African nations and people of African descent. They highlighted that reparative justice should include formal apologies, truth-telling processes and various forms of reparations, in order to foster reconciliation, justice, equality and solidarity in society.

Three tales of biodiversity revival in Latin America

From the highest cloud forest in the Andes to one of the smallest fish in a Chilean river, biodiversity is the invisible thread that ties ecosystems together and sustains agricultural production and food security. Biodiversity is crucial for ecosystems and agricultural production, especially in Latin America and the Caribbean, which host about 50% of the world’s primary forests. These forests play vital roles in carbon sequestration. However, biodiversity is declining due to human activities and climate change. The agrifood sector depends on biodiversity for services like soil health, pest control, and pollination. Acknowledging this, three GEF-funded FAO projects are dedicated to conserving and restoring ecosystems in Brazil, Chile, and Venezuela.

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.

Where hope roars

Diego, Hilda, Juan, and their son Hugo are farmers in Comandante Andresito, Argentina, where together they face the same challenge, living alongside jaguars, known as 'yaguareté' in the region. These large felines, significant in indigenous culture, have seen their population decline by 50% since the 19th century, largely due to habitat loss and conflict with livestock farmers. In Argentina, the situation is even more dire. It’s estimated that 95 percent of the jaguar's original habitat has been lost. To alleviate these issues, a protection insurance program was introduced, providing farmers with financial compensation and technical support following confirmed jaguar attacks.
