Now is the time to silence the bombs

This year, the International Day against Nuclear Tests (29 August) comes amid rising geopolitical tensions and growing nuclear risks — including the disturbing prospect of a return to nuclear testing. In 2025, we commemorate the 80th anniversary of the first nuclear test. We must never forget the legacy of over 2,000 nuclear weapons tests carried out over the past eight decades. The effects of these explosions have been horrific. Now is the time to silence the bombs before they speak again.

Lakes worldwide are in decline. Here's why and what to do.

There are over 100 million lakes across the globe, but many are undergoing dramatic changes. Climate change, pollution, and excessive water use are causing lakes to shrink, overflow, or even change color. According to Dianna Kopansky of the UN Environment Programme (UNEP), some of the world’s most iconic lakes have deteriorated significantly in recent decades. She warns that reversing this trend is essential, as countless people depend on lakes for their survival. In honor of the first World Lake Day, here’s a closer look at the biggest threats to the world’s lakes – and what can be done about them.

Turning knowledge into action: Scaling solutions for disaster risk

Knowledge, especially practical know-how, is crucial for countries to address development challenges and enhance resilience to disasters. Many people and businesses in emerging economies lack insurance against natural disasters, forcing governments to absorb the costs. In 2023, earthquakes in Morocco, Türkiye, and Syria highlighted this gap. In Morocco and Türkiye, public-private insurance partnerships demonstrated effectiveness in these cases, expanding access and affordability of risk coverage. The World Bank Group Academy launched the Disaster Risk Finance Academy to facilitate sharing of best practices among global experts and officials, with a goal of transforming knowledge into actionable solutions.

Lesotho´s potato farmers: From subsistence to prosperity

In a remote town in Lesotho’s Maseru District, farmer Mabitsoane Diholo has transformed her life through potato farming. Once merely for family consumption, potatoes have become her livelihood, contributing to her home and children's education. In 2022, Lesotho joined the One Country One Priority Product (OCOP) initiative by the Food and Agriculture Organization of the United Nations (FAO), supporting 750 farmers like Mabitsoane. With improved seeds and access to markets like Maluti Fresh Produce Market, farmers are shifting from subsistence to commercial farming, enhancing their incomes and becoming entrepreneurs, thanks to better practices and coordinated efforts.

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.

Ending Poverty

While global poverty rates have been cut by more than half since 2000, one in ten people in developing regions still lives on less than US$1.90 a day — the internationally agreed poverty line, and millions of others live on slightly more than this daily amount.

When war comes home, with Yacoub El Hillo (AAN S11-E4)

“[Serving refugees] is not a job, it's a mission, and there's always fire in the belly that keeps you wanting to do more, but also never giving up. This is the UNHCR I joined.”

Yacoub El Hillo spent more than thirty years serving refugees and displaced people in some of the world’s worst conflict zones. But when cataclysmic war erupted in his hometown of Khartoum, Sudan, the Regional Director for Africa at the United Nations Development Coordination Office (DCO) had to help his own family flee the violence.

“I don't think there's any home in Khartoum that was spared … the assumption is that everything is gone.”

Having served in more than 16 duty stations, from Liberia to Syria, Somalia and Afghanistan, Yacoub El Hillo has rarely seen any conflict as devastating as the one currently decimating Sudan. In this episode, he reflects on the scale of the human suffering there, looks back on a rich and varied career with the UN, and shares why all nations deserve a chance to strive for a brighter future.

As famine grips Gaza, families turn to desperate measures to survive

Hedaia cradles her 18-month-old son, Mohamed, who suffers from muscular atrophy and is now skeletal due to severe food shortages in Gaza. By the end of September, it is projected that 641,000 people will face catastrophic hunger. Famine has been confirmed in Gaza at the highest Integrated Food Security Phase Classification (IPC) level, which is the global standard for measuring food insecurity. An additional 1.14 million will face Emergency conditions, while 396,000 will be in Crisis. The situation is worsened by ongoing conflict and restricted aid access. Experts call for urgent aid and a ceasefire to save lives, marking the first confirmed famine in the Gaza Strip.

Severe aid cuts threaten survival of returnees in North Kivu

Decades of armed conflict in North Kivu, DRC, have devastated infrastructure and lives. Since January 2025, over 1 million displaced people have been pushed to leave camps and return to villages, but many struggle to access basic services, especially healthcare. In Kabase village, the only health facility is in ruins, with stolen essential equipment, including a vaccine refrigerator. Nurse Lukoo Joseph highlights the dire situation, stating the community cannot afford healthcare. Despite severe funding cuts, the UN aims to assist 11 million people this year but requires more support to meet rising needs. You can help make a difference. Support the DRC Humanitarian Fund.
