Where will AI send travellers next, and who gets to decide?

As travellers increasingly rely on artificial intelligence to decide where to stay, what to see and where to go, the technology is reshaping how destinations are discovered and experienced. World Tourism Day 2026 puts this transformation centre stage in El Salvador, where tourism meets the global conversation on AI governance. The event explores how emerging technologies can create new opportunities for destinations, businesses, governments and tourism workers, while helping to build a shared vision for the sector’s digital future.

World Tourism Day, observed since 1980, exists to make the world see what tourism is worth.

Justice for People and Planet in the Digital Age

As technology transforms our lives, it is also reshaping crime — and challenging how justice systems respond. From 26 September to 1 October, the 15th UN Crime Congress in Abu Dhabi brings together governments, civil society, academia and experts to explore how criminal justice can keep pace with rapid technological change. Discussions will focus on protecting people, especially the most vulnerable, and the environment from crime, violence and exploitation. From access to justice and smarter prevention to stronger partnerships and emerging forms of crime, the Congress will seek practical solutions for a safer, fairer digital age.

Moving beyond crisis

Surviving a crisis is only the beginning. A child still needs a school, a farmer safe land and a family a place to call home. Yet more than 160 million people lack the support they need to rebuild their lives. UNDP is working to close the gap between emergency relief and long-term recovery, restoring services and livelihoods while crises are still unfolding. From clearing dangerous land in Ukraine and Syria to supporting businesses in Afghanistan and housing in Gaza, the goal is to help communities regain stability, rebuild local economies and prepare for a future beyond crisis.

Children want a say in their education

Children are calling for a greater say in decisions about their education. At a UN Human Rights discussion on the right to education, young participants highlighted barriers that continue to exclude children from learning and stressed the need for education systems that respond to different needs and circumstances. Inclusive education requires more than access to a classroom: it means removing discrimination and other barriers, providing appropriate support and ensuring children can participate in decisions that affect their learning.

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.

The Spotlight series

This series shines a light on communities facing conflict, displacement, public health emergencies and other humanitarian challenges around the world. Drawing on reporting from across the UN system, it amplifies voices from countries including Haiti, Gaza, DR Congo, Yemen, Afghanistan and Myanmar, to foster understanding, encourage engagement, and help mobilize support, assistance, and protection for the most vulnerable people.

Climate Change

Climate Change is one of the defining issues of our time and we are at a pivotal moment. From shifting weather patterns that threaten food production, to rising sea levels that increase the risk of catastrophic flooding, the impacts of climate change are global in scope and unprecedented in scale. Taking decisive action today will make adapting to these impacts in the future more effective and less costly.

UN Advocate Joseph Gordon-Levitt calls for human-centred AI rulebook

As artificial intelligence rapidly reshapes society, actor and UN Global Advocate for Human-centric Digital Governance Joseph Gordon-Levitt is calling for stronger rules to ensure the technology remains accountable to people.

In an interview with UN News, Mr. Gordon-Levitt argued that AI should be “governed by people and for people.”

His comments come as the global debate on AI guardrails moved to UN Headquarters this week, with many world leaders citing concerns from the podium. 

Speaking to UN News’s Charlotte Dawson, he said one of his biggest concerns is the growing influence of AI on children, particularly its potential effects on attention and human relationships.

Armed drones and the growing toll on civilians

For civilians caught in conflict, danger increasingly comes from the sky. Béatrice Maniraguha, 23, a disabled mother of three, displaced by conflict in DRC's North Kivu, where drone attacks are prevalent has been sheltering in a hangar for a year. Armed drone attacks worldwide rose by at least 4,000 per cent between 2020 and 2024, according to OCHA. In Sudan, drone strikes accounted for 80 per cent of recorded civilian deaths in the first four months of 2026, while drones were a leading cause of recorded civilian deaths and injuries in Ukraine in 2025. Beyond casualties, strikes are damaging hospitals, water systems and aid facilities and making humanitarian work more dangerous. The UN is urging parties to protect civilians and comply with international law in the use of armed drones.

Hunger increases as humanitarian funding falters

Hunger is rising just as resources to fight it are under growing pressure. Some 266 million people face acute food insecurity, while 2.69 billion cannot afford a healthy diet. Climate shocks are adding to the strain: the current El Niño cycle could push another 49 million people into acute hunger by the end of 2027. Yet early action can make a difference. In 2025, WFP helped 6.3 million people prepare for climate shocks before disaster struck. WFP is calling for action to end conflict, protect humanitarian access, close funding gaps and invest in early warning and innovation.
