Rangelands: Recognize. Respect. Restore.

On World Day to Combat Desertification and Drought  (17 June), let's recognize the vital importance of rangelands. Covering more than half of the Earth’s land surface, they support nearly two billion people and provide almost 70% of global livestock feed, making them essential for food security, biodiversity and climate resilience. Yet up to half of the world’s rangelands are degraded or at risk. This observance calls for greater recognition, protection and restoration of these critical ecosystems and the communities that steward them. Join the campaign: "Rangelands: Recognize. Respect. Restore".

The observance coincides with the celebration of the UN International Year of Rangelands and Pastoralists in 2026.

UNESCO charts a new path for people and nature

UNESCO’s biosphere reserves reverse the traditional conservation model by treating local communities as partners rather than obstacles. With more than 700 reserves in 142 countries, covering 7.5 million square kilometers, these “living laboratories” integrate biodiversity protection, scientific research, and sustainable livelihoods. Last week, 250 experts from 34 countries gathered in Paraguay for the Man and the Biosphere Programme’s International Coordinating Council. The host, Paraguay’s Itaipu Biosphere Reserve, protects the country’s largest remaining Upper Paraná Atlantic Forest corridor while supporting 250,000 residents. Through restoration efforts, nearly 4 million trees have been planted. The meeting also welcomed 14 new reserves, including the first in Montenegro and Timor-Leste.

From Innovation to Impact: AI’s Role in Transforming Global Health

Good health underpins education, employment, and economic growth, yet 4.5 billion people still lack access to essential health services. AI offers practical solutions by expanding access through virtual triage, remote diagnostics, and clinical decision support, helping patients receive timely and appropriate care. Examples from Brazil, Ethiopia, and India show how low-cost “Small AI” tools can improve disease detection and maternal health in low-resource settings. AI can also strengthen health workers’ capacity, create jobs across the health ecosystem, and improve efficiency. However, realizing its potential requires investment, training, strong governance, privacy protections, and safeguards against bias. With responsible deployment, AI can help build stronger, more equitable health systems and expand quality care to millions.

Betting on herding and herself

Before dawn breaks over Nepal’s eastern highlands, 28-year-old Subita Rai tends her herd of 20 yaks and chauris, continuing a tradition many of her peers left behind in search of opportunities abroad. Defying gender norms in a male-dominated profession, she balances herding, family responsibilities, and the growing challenges of climate change. Through support from the  Food and Agriculture Organization of the United Nations-hosted Mountain Partnership Secretariat and partners, Subita gained training and access to cheese-processing facilities, enabling her family to turn perishable yak milk into higher-value artisanal cheese. The shift has reduced losses, improved income stability, and strengthened local livelihoods. Now a cooperative board member, Subita represents a new generation of women pastoralists building resilient futures in Nepal’s mountain communities.

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.

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.

Protecting ocean gold: The Pacific’s sustainable tuna success story

The ocean sustains life and livelihoods, producing at least half of Earth’s oxygen, supporting vast biodiversity, and providing food and jobs for millions. Yet overfishing and ecosystem decline threaten its future. In the Pacific, however, a different story has emerged. Through more than 20 years of collaboration among 14 Pacific Island nations, regional organizations, scientists, and development partners, Pacific tuna fisheries have become the world’s first major tuna fishery where all four key stocks are harvested sustainably. Science-based management, regional unity, and initiatives such as the Vessel Day Scheme have strengthened food security, generated billions in economic value, and supported thousands of jobs. The Pacific’s success demonstrates how cooperation, stewardship, and long-term investment can protect marine resources while advancing sustainable development.

Young leaders driving climate resilience across East Africa

Across East Africa, climate change is driving displacement and disrupting livelihoods, from rising waters along Burundi’s Lake Tanganyika to recurrent flooding in Kenya’s informal settlements. As communities face growing climate pressures, young leaders are developing practical solutions to build resilience. In Burundi, ISHAKA 2250 supports flood-displaced families through reforestation, livestock distribution, and livelihood restoration. In Kenya, Dreams Redefined combines climate action with community development through improved waste management, environmental practices, and financial literacy. Supported by an IOM climate mobility programme and grants, these youth-led initiatives demonstrate how local action can help communities adapt, recover, and thrive. Their work highlights the vital role of young people in addressing climate-driven displacement and building a more resilient future.
