Give blood, give hope

On 14 June, the world celebrates World Blood Donor Day, a global tribute to the millions of voluntary, unpaid blood donors who give others a second chance at life. Their generosity not only saves lives but also strengthens communities and embodies the spirit of solidarity. It’s a day to say thank you, but also to spotlight the ongoing, urgent need for safe, regular blood donations. This year, we honor hope, the kind you give with every drop of blood. Because millions of patients around the world rely on blood transfusions every year, hope flows through every donation.

The campaign encourages both new and existing donors to give blood regularly, helping to ensure a stable and sufficient blood supply.

The real fertility crisis

Millions of people around the world are unable to have the number of children they want – whether they want more, fewer, or none at all. Recently, fertility declines are making headlines, with women all too often blamed for these demographic shifts. Some governments are employing drastic measures to incentivize young people to make fertility decisions in line with national targets. But the real crisis is that the most consequential reproductive decision a human being can make – when, whether and with whom to have a child – is being undermined. Together with YouGov, UNFPA conducted a survey of 14 countries to ask people whether they are having the families they desire. We found that alarmingly high proportions of adults are unable to realize their fertility intentions.

Bolivian environmentalist fights for Amazon protection amidst threats

Marcos Uzquiano Howard, a Bolivian park ranger and defender of the Amazon, has always held a deep respect for nature, learning to value biodiversity from his mother and grandmother. Despite his commitment to protecting the environment, he has faced harassment, threats, and persecution from institutional bodies like the National Service of Protected Areas (SERNAP) due to his opposition to illegal mining and deforestation. Although he won a ruling for his reinstatement, he still awaits protective measures to continue his work. In a significant development for environmental justice, Bolivia held its first public environmental hearing under the Escazú Agreement on April 23, 2025, focusing on the protection of the jaguar and environmental defenders like Uzquiano.

The seaweed capital of Philippines

In Tawi-Tawi, Philippines, seaweed farming is a vital livelihood for many, but challenges threaten its future. Farmers like Imilita Mawaldani Hikanti have relied on cultivating agal-agal seaweeds for generations. The province, known as the “Seaweed Capital of the Philippines,” produces around 40% of of the country’s 600 000-tonne annual output of seaweed. However, volatile prices and competition have driven local prices down to PHP 25 per kilo (about USD 0.44), leading to losses for farmers. Additional issues like ice-ice disease caused by climate change exacerbate the situation. To address these challenges, FAO and local authorities have launched a project to enhance seaweed production and value chains.

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.

Greening the Mexican desert

In the Mixteca region of Oaxaca, Mexico, communities face increasingly unreliable rains and severe droughts, worsened by climate change. The drought of 2022 was notably harsh, highlighting the need for innovative solutions to adapt to the changing climate. With support from the Global Environment Facility and UNDP, the local organization Alternativas y Participación Social developed a mobile solar-powered water pump to address water scarcity. This pump can be used across different wells to store and irrigate drought-resistant amaranth crops, a drought-tolerant grain and ‘superfood’ native to Mexico. The project produced 20 units for local cooperatives and provided training on their use and maintenance.
