Sheltering hope: Highlight on urban challenges

World Habitat Day, celebrated each year on the first Monday of October, is observed globally on 6 October with a focus on urban crisis response. The UN uses this day to reflect on the state of cities and the right to adequate shelter for all. This year’s theme addresses urban crisis response, such as climate change, conflict, and inequality. With over 122 million people forcibly displaced, many in urban areas, the Day emphasizes the need for inclusive, sustainable solutions that support urban planning, social cohesion, and resilient local governance. Follow the celebration on UN Web TV.

Myanmar’s long road back

Six months after a devastating earthquake hit central Myanmar, particularly Mandalay, the area shows signs of destruction with collapsed structures and a need for recovery. The country, already facing civil war and political unrest, struggled further with the added impact of the disaster on poverty and livelihoods. In response, community groups and international partners rallied together. With support from the United Nations Development Programme (UNDP) and contributions from nations like Korea and Japan, a comprehensive plan was implemented quickly to clear debris, provide temporary shelters, and ensure access to clean water, marking a significant step in the early recovery process.

A mother carries Sudan’s tomorrow through her children

In Abu Shouk camp, North Darfur, Jamila and her four children live under a thin plastic sheet, facing daily struggles for survival. Once, they ran a grocery shop in Zalingei, providing dignity and community. War changed everything; a shell destroyed their home and her husband disappeared without a trace. Fleeing with her children, she endured a harsh journey filled with hunger. Now at the camp, she works in exchange for food, but it’s never enough. Despite the overwhelming loss and uncertainty, Jamila remains determined to keep her children alive. With millions displaced in Sudan, her story reflects the profound struggle for safety and hope.

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.

IMF flags crypto’s role in criminal finance

While countries came together in the late 80s to fight money laundering and the financing of terrorism, technology and the advent of virtual currencies have further complicated the tracking of illicit financial flows across borders. Over $51 billion in cryptocurrency was used by criminals last year to circumvent traditional banking regulations. Chady El Khoury is an assistant general counsel and heads the Financial Integrity Group at the IMF. In this podcast, El Khoury says the anonymity of virtual currency transactions is supercharging the ability for criminals to grow their empires

The aging countryside

Peru is a leading producer of coffee and cocoa, ranking fifth and seventh globally, respectively. These crops are mainly grown by small farmers on the Andean slopes, supporting over 200,000 coffee and 100,000 cocoa families. Cocoa cultivation has been actively promoted as an alternative to illegal coca leaf production, leading to a significant expansion from 41,000 hectares in 2000 to 177,000 hectares today. However, both sectors face challenges like low competitiveness, poor sustainability, and limited access to training and financial services. Most family farms are small, and producers often rely on traditional practices, resulting in low yields and contributing to deforestation. High-quality producers are scarce, and market prices are volatile. Additionally, an aging population continues to bear the burden of agricultural labor in these communities.

When wells run dry

Ugbaad Ducaale, a camel herder and mother of three in Somaliland's Awdal region, travels 20 kilometers to fetch water as local wells have dried up. She leaves one child at home and takes the others on the long journey, causing them to miss school. This is the harsh reality for millions in Somalia, where drought has intensified after yet another failed rainy season. Families already burdened by conflict and displacement now face worsening hunger. Meanwhile, the humanitarian community struggles to meet the rising needs due to global funding cuts. Here are five things to know about the crisis.
