Addressing the condition of conjoined twins

Conjoined twins are a rare type of identical twins that share a placenta and an amniotic sac. The estimated incidence of this condition can be 1 in 50,000 births. On the World Conjoined Twins Day (24 November) we emphasize the need to address the condition of conjoined twins by raising awareness of their cases at all levels and through a life-course approach, as well as by advocating for their well-being and social inclusion, while taking into account relevant agreed international standards, norms and principles.

Ending child poverty: Our shared imperative

Poverty severely impacts childhood, endangering children's lives, health, and development while denying their fundamental rights. Today's children face crises like conflict and climate change, exacerbating their suffering. While monetary poverty is critical, it only tells part of the story; many children experience deprivations in housing, nutrition, sanitation, education, and healthcare. This multifaceted poverty leads to poor health outcomes, limited learning opportunities, and bleak future prospects. Ultimately, poverty threatens societal stability and economic growth, fostering conditions conducive to violence and extremism. Urgent action is needed to address these issues.

Pakistan's Anti-Rape Crisis Cells transforming support for survivors.

Nadia, a young tutor from Karachi, faced harassment through WhatsApp from a trusted neighbor, leading to a traumatic assault. In the past five years in Pakistan, around 1.8 million women have experienced cyber-crimes, but only 3.5% of offenders face conviction. The Prevention of Electronic Crimes Act (PECA) 2016 aims to combat such crimes, but enforcement is weak. After her attack, Nadia found support at Pakistan's first Anti-Rape Crisis Cell, established in 2023. There, she received medical, legal, and psychological help, helping her regain confidence and a sense of justice, inspiring her to advocate for all silenced women.

Disasters cost global agriculture $3.26 trillion over three decades

Agriculture and food security face severe threats from increasing disasters, which have caused an estimated $3.26 trillion in losses over the past 33 years, about $99 billion annually. A new report by the Food and Agriculture Organization (FAO) highlights how digital technologies are enhancing risk monitoring and response. It provides a comprehensive assessment of how various disasters disrupt food production and nutrition. Digital innovations are facilitating a shift from reactive crisis management to proactive resilience-building, with tools such as parametric insurance and early warning systems enabling communities to mitigate risks effectively.

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.

Vanishing rivers: Water crisis impacts women's lives in southern Angola

Helena collects water from a borehole in Giraul village in Angola, where the river has stopped flowing. Women are desperate to collect water for their families amid prolonged drought, but cholera outbreaks have been reported in the area due to contaminated water. Clean water is essential during childbirth – without it, the risk of infection increases. Birthing equipment must be properly cleaned, and new mothers need safe water for bathing. Maria, a traditional midwife in Giraul, who provides a lifeline for women who can’t make the journey to a hospital, asks women to collect water before they go into labour. UNFPA is training midwives to help women deliver safely, as well as delivering youth programmes that help pregnant adolescents get the care and support they need and stay in school. UNICEF and the World Food Programme are working with the Government of Angola to manage drought and provide water and food support to the region.

What happens when we trust youth to lead climate action?

The world is heating. Inequalities are deepening. And yet, across continents, young people are stepping into the cracks of broken systems and reimagining what’s possible. While the world works to respond to the climate crisis, youth from around the world are showing what happens when youth are not just invited to the table but trusted to lead. This article introduces five of these young leaders: Sundus from Pakistan (seen here with her team that brings damaged reefs back to life), Elvis from Liberia, Luís from Bolivia, Pablo from Colombia, Specioza from Uganda. All of them, with support of Youth4Climate, are building new systems of food, energy, mobility and education, from the ground up. Their projects are different, but their experiences and drive are shared. What they show us is clear: when young people are trusted and supported with the right resources, they can drive meaningful and lasting change.
