United in Diversity: Embracing Peace and Solidarity

Rooted in the UN's post-World War II mission to prevent conflict and uphold human rights, the UN General Assembly declared the International Day of Living Together in Peace (16 May) to emphasize the importance of accepting and respecting differences while striving for peace, tolerance, inclusion, and solidarity, and to promote reconciliation and sustainable development by encouraging forgiveness, compassion, and cooperation. Likewise, various UN initiatives emphasize that peace requires positive engagement and the elimination of discrimination and intolerance, not just the absence of conflict.

Humanitarian funding cuts threaten women’s rights: What’s at stake and how to help

A new UN Women report warns that half of women-led and women's rights organizations in humanitarian crisis zones may close within six months due to funding cuts, jeopardizing vital services for millions of women and families. In a survey of 411 organizations across 44 crisis-affected countries, 90% reported financial impacts from reduced foreign aid, with over 60% already cutting back on services like emergency healthcare and shelter. Between 2021 and 2022, women’s rights organizations received less than 1% of humanitarian aid funding and heavily depend on government support, which is now diminishing. These organizations play a crucial role in delivering essential humanitarian services in Myanmar, Palestine, Sudan, and Afghanistan.

What are National Adaptation Plans and why do they matter?

National Adaptation Plans (NAPs) help countries incorporate climate adaptation into their existing policies and programs, particularly in key sectors like agriculture and water. By proactive planning, governments can reduce risks and enhance climate resilience. NAPs also facilitate access to climate finance and promote collaboration across different societal levels to implement adaptation measures, such as improved water management and resilient infrastructure. NAPs are especially vital for the 1.2 billion people already facing severe climate hazards, particularly in Least Developed Countries (LDCs) and Small Island Developing States (SIDS), which are highly vulnerable to climate impacts.

Where the wind carries hunger

Lutfi Çetin, an expert in rust research with over 30 years of experience, is inspecting wheat fields in Türkiye, where the threat of rust infections looms large. Wheat is crucial for food security in Central Asia and the Caucasus, but airborne fungal diseases known as wheat rusts—such as yellow, leaf, and stem rust—pose a significant global threat, destroying up to 15 million tonnes of grain annually. These rust strains, which have evolved and spread more rapidly than in the past, require effective long-term management through surveillance and the development of disease-resistant wheat varieties. In response to this challenge, a coalition of scientists, farmers, and governments from several Central Asian countries, supported by the Food and Agriculture Organization (FAO) and Türkiye, is working together to strengthen defenses against these pathogens.

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.

Lives changed forever by war in Gaza

The weeks since the breakdown of the ceasefire in Gaza have seen yet more pain and tragedy piled on top of what was already almost unfathomable loss. The ongoing bombardments, and the complete block on aid and supplies entering the Gaza Strip, have strained the humanitarian response to the limit. Since the start of this war in Gaza, thousands of children have been killed and many thousands more have been injured. But even for those who survive the injuries, life will never be the same. These are some of their stories.

The small-scale farmers tending to Mother Earth

Our planet sustains all life by providing clean air, water, and food. Rural communities, including farmers, fishers, and herders, recognize that their well-being is connected to the health of the earth. Diverse ecosystems support food production and economic prosperity. To support these communities, the International Fund for Agricultural Development (IFAD) collaborates with governments to finance sustainable projects, investing $4 billion in sustainable land management and $1.4 billion in climate finance since 2000. From 2018 to 2023, 70% of IFAD projects focused on conserving biodiversity, and 60% promoted agroecological practices. These initiatives empower rural people to care for the environment while benefiting from its resources.
