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.

If everything is connected, everything is important

Dayana Blanco, from Bolivia, and Maggie Bukowa, from Zambia, represent two influential voices of change within a global network dedicated to talent, conviction, and passion, which serves as the foundation for the Equator Initiative. This initiative recognizes the invaluable wisdom and knowledge of Indigenous Peoples and local communities worldwide. Supported by the governments of Norway and Germany, the Equator Initiative aligns with the UNDP's Nature Pledge and Climate Promise initiatives, which aim to enhance livelihoods while safeguarding nature and human rights. The inaugural Equator Prize was established in 2002 during the World Summit on Sustainable Development in Johannesburg, also known as Rio+10, building upon the commitments made during the landmark 1992 Earth Summit.

Youth Rights Academy: Learning skills to lead change

A group of 45 young human rights advocates from all over the world gathered recently in Geneva for a Youth Rights Academy. They emphasized the importance of knowing their rights to create real change, with speakers like Avril Murillo from Bolivia and Yara Al-Zinati from Gaza highlighting how young people understand the urgency of the situation today. The Academy was set up through a partnership between UN Human Rights and Qatar’s Education Above All, focusing on empowering youth, especially in conflict zones. They previously launched a Youth Advocacy Toolkit to help with this mission. During the Academy, participants engaged in workshops covering various topics such as international law, education rights, the climate crisis, and how to use social media for advocacy.

From sea to soil

Paulo Benedito, a lifelong fisherman from Quissanga, a small coastal town in northern Mozambique’s Cabo Delgado province, faced devastating changes in 2021 when armed Islamist insurgents attacked his community, forcing him and his family to flee. They sought refuge at the Meculane Centre for Internally Displaced Persons, where Paulo had to transition from fishing to farming. Despite the challenges, he embraced agricultural training offered by the Food and Agriculture Organization (FAO). He soon excelled in his new role, expressing a newfound preference for farming over fishing, as it provided more stability and ensured food for his family.

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.

Circular fashion: the $700 billion opportunity to #beatpollution

The global textile sector is massive, but so is its environmental impact. The current "take, make, and dispose" model needs a revolution. InTex, a programme by the UN Environment Programme and funded by the European Commission and Denmark, is working to transform the industry into a sustainable, circular model through better data. By shifting to circular business models, and reducing carbon footprints across Africa and Asia, it has the potential to generate $700 billion by 2030. Find out more at UNEP InTex.

Chad: the reality of hunger

In Chad, more than 3.3 million Chadians (19% of the population) are facing high levels of acute food insecurity. The continued influx of people fleeing conflict in Sudan, persistent insecurity, and increased risks of flooding and drought place the country on the list of hotspots for malnutrition and hunger.

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.

Guardians of what remains

Franklin Olivo was exploring the Tagarkunyal jungle in Panama's Darién province when he encountered a harpy eagle, the largest eagle in the Americas. This bird, recognized as Panama's national symbol, holds significant cultural importance for Indigenous groups and plays a crucial role in the rainforest ecosystem. However, it faces threats from hunting and habitat loss, particularly in the Darién region, which is also plagued by poverty and illegal activities. Despite economic pressures from agriculture, logging, and mining, the Guna and other Indigenous Peoples play a vital role in conserving the rainforest through their traditional knowledge and community stewardship. Franklin's sighting of the eagle was part of a monitoring project initiated by Guna leaders to empower local youth as environmental guardians.

In Afghanistan change starts close to home 

Earlier this year, Fatima, a resident of a remote village in Herat Province, received humanitarian cash assistance that provided much-needed relief. However, two local men seized the funds from 23 recipients, claiming they needed redistribution. Despite the risk of retaliation, Fatima contacted Awaaz Afghanistan, a nationwide platform for reporting issues related to humanitarian aid. The team acted on her complaint, leading to a field visit that confirmed the misuse of funds. Within ten days, each affected household received their full assistance. This case underscores the impact of speaking out and the responsiveness of humanitarian actors, facilitated by Awaaz Afghanistan, which has assisted nearly 600,000 calls and reached almost 4 million people.
