Hiroshima and Nagasaki: 80 years after the atomic bombings

This year marks the 80th anniversary of the atomic bombings of Hiroshima and Nagasaki, Japan, on 6 and 9 August. Every year, Hiroshima holds the Peace Memorial Ceremony to console the souls of those lost to the atomic bombing, as well as pray for the realization of lasting world peace. Weapons of mass destruction, in particular nuclear weapons, remain a major concern due to their destructive power and threat to humanity. The UN has sought to eliminate such weapons ever since its establishment. Let’s work together to banish these devices of destruction to the history books, once and for all.

Even though nuclear weapons have only been used twice in warfare, approximately 12,500 of them are still in existence today.

Risk is our new reality

Development has led to significant achievements like longer lives and less poverty, but these gains are threatened by deep global changes, including geopolitical tensions, shifting populations, and climate shocks. The UNDP's report "Development at Risk: Protecting Gains and Unleashing Opportunities Amid Crisis" urges the global community to prioritize risk reduction. It recommends three key actions: rethink development outcomes by incorporating measures of wellbeing and resilience beyond GDP, reimagine governance through empowering local institutions and data use, and reboot cooperation by investing in long-term, flexible solutions. These strategies aim to transform risks into opportunities for advancing development effectively.

UNHCR and IOM launch "Train-to-Hire" to boost refugee employment

The International Organization for Migration (IOM) and the UN Refugee Agency (UNHCR) have launched a "train-to-hire" program for refugees in the Asia-Pacific region, funded by the Australian Government for an initial 22-month period. This initiative aims to enhance refugee skills and connect them with international job opportunities, addressing labor market gaps and promoting self-reliance. It seeks to strengthen collaboration among UN agencies and facilitate safe migration, leveraging refugees' skills to reduce reliance on irregular routes. Despite significant numbers of skilled refugees, barriers to employment remain, making this targeted training vital for aligning talent with labor needs.

They feel a responsibility to preserve these traditional strains that have adapted to their local soil and climate. By cultivating these heirloom varieties for their bakery, they aim to share their heritage with customers. What began as a simple passion has turned into a commitment to rediscover and rejuvenate forgotten Georgian wheat varieties.

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.

What next for Syria’s refugees, with Gonzalo Vargas Llosa (AAN S11-E1)

Welcome back to Awake at Night! We are launching season 11 and our first episode is an interview with the UN High Commissioner for Refugees’ Representative to Syria: Gonzalo Vargas Llosa.

“Something happened to me in those hours that we spent in that orphanage, because I remember that on the plane back ... I told my father...I don't want to be a writer for sure. Second, I don't want to be a translator or an interpreter. I want to do humanitarian work.”

Rather than follow in the footsteps of his late father, a Nobel-prize winning writer, Gonzalo Vargas Llosa opted instead to serve humanity. Now the UN High Commissioner for Refugees’ Representative to Syria, he just witnessed a historic end to 14 years of conflict and crisis.

“There were these long, long lines of cars of Syrian refugees coming back from Lebanon. So many of them stopped the car the moment that they entered Syria, they got out of the car, they kissed the ground … saying we are so happy to be back in this new Syria.”

The fall of the Assad regime has brought fresh hope for millions of displaced Syrians. Yet with a lack of housing, services and jobs still preventing most from returning, the UN is calling for action to support returnees.

Gonzalo Vargas Llosa looks back on a career full of seismic turning points, and reflects on the painful sacrifices of a life spent in service.

Sudan: Born in the shadows of shattered walls

When war erupted in Sudan in April 2023, it tore a deadly path through the capital, Khartoum. In the years since, fighters have brutally targeted civilians across the country, resulting in the world’s largest displacement crisis with some 12 million people forced from their homes. Today, as families begin to return to Khartoum, the scars of conflict remain painfully visible, especially in the shattered health system. UNFPA, the United Nations sexual and reproductive health agency, is part of the effort to restore what has been lost.

Tigers know no borders

In April 2025, wildlife officials confirmed the sighting of the critically endangered Malayan tiger in Southern Thailand after a decade-long absence. This discovery, captured by camera traps in Bang Lang National Park, also revealed other wildlife like tapirs and wild elephants, emphasizing the idea that thriving tiger populations benefit the entire forest ecosystem. The Malayan tiger, native to Peninsular Malaysia, numbers fewer than 150 in the wild. Successful population rebounds in countries like Bhutan and India highlight the importance of political commitment and conservation efforts supported by organizations like the United Nations Development Programme (UNDP) and the Global Environment Facility.
