Rays of hope for sustainable tuna fishing

Since the UN designated May 2 as World Tuna Day to highlight the importance of responsible tuna fishing, significant progress has been made. In 2017, only 75% of catch came from sustainable tuna stocks; today, that figure exceeds 90%. This recovery is the result of coordinated efforts by governments, fisheries organizations, scientists, and fishers, supported by the FAO-led Common Oceans Program. However, vigilance remains essential. Climate change, bycatch, and other challenges persist. Global cooperation is key to securing truly sustainable tuna fisheries and preparing for what lies ahead.

Out of the 23 tuna stocks, only two stocks are still being overfished according to the latest data.

UNHCR organizes first voluntary return convoy from northeastern Syrian camps

On April 15, 84 residents from the Areesha camp for internally displaced people (IDPs) in northeast Syria began their journey home after more than seven years, assisted by UNHCR, the UN Refugee Agency. Among them was Shahrzad and her two daughters, aged 7 and 8, who were excited to reunite with their father in Al Mayadin, after he spent two months in Damascus for medical treatment. Shahrzad expressed her long-awaited joy, having fled a military offensive in 2017. Her youngest daughter was born in the camp, and both children have no memories of their parents' hometown. While UNHCR plans to support the return of about 3.5 million Syrian refugees and IDPs by 2025, their efforts face significant obstacles due to drastic cuts to global humanitarian funding, resulting in job reductions and the closure of community centers in Syria.

Dignity and struggle: The right to land in Honduras

In the 1970s, the Bajo Aguán region of Honduras became the focus of agrarian reform, with hundreds of families relocated to its fertile lands. However, this area has since become plagued by violence and corruption, leading to land dispossession and murders, as noted by Bardia Jebeli from the UN Human Rights office in Honduras. Legislative changes in the 1990s facilitated land purchases by agro-industrial entrepreneurs, further exacerbating these issues. Rural poverty is significant, with many affected individuals being small-scale farmers facing systemic discrimination and human rights challenges. Despite this, communities in Bajo Aguán, led by women and youth, resist these adversities, viewing their land as a vital life project. International support, especially from UN Human Rights, has provided hope and solidarity, emphasizing the importance of their role as allies in the fight for justice and equity in land rights.

Out of its cocoon

A new silk farming industry is emerging in Mukono, Uganda, managed by Waiswa Aggrey Mubeerwa for the Seres Textile Company Limited. Established in 2019, the facility awaits the arrival of an extracting machine to begin exporting silk. This initiative is part of a South-South Cooperation (SSC) project implemented by FAO, working with the Ugandan government and China's Ministry of Agriculture. Uganda's climate is ideal for mulberry trees, the sole food for silkworms. With proper training and resources, farmers can significantly increase their income, as a kilogram of silk can earn around USD 50 in China. By the end of 2024, the project had distributed 200,000 mulberry cuttings and trained 44 farmers. The SSC project aims to enhance agricultural productivity across Uganda, benefiting 70,000 farmers in various sectors, transitioning from subsistence farming to commercial operations essential for poverty alleviation.

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.

‘If you want to make your country great again, don’t retreat from the world’: UN relief chief

UN Humanitarian Affairs chief Tom Fletcher has been forced to make “brutal cuts” to his organization, as major donors in the rich world slash their aid and international development spending.

UN News’s Conor Lennon spoke to him on Thursday via video-link from the UN offices in the Afghan capital Kabul, at the end of a three week visit to some of the most vulnerable communities in the country, where he has witnessed first-hand the deadly consequences of the dramatic aid slowdown.

Mr. Fletcher has publicly challenged policymakers who signed off on cuts to come to Afghanistan to see the effect they're having on the population, saying that “the effect of aid cuts, is that millions die”.

A bio-cultural treasure

India is recognized as a mega-diverse country, with the Northeast region—comprising eight states—being a significant biodiversity hotspot that holds over 30% of the nation’s biodiversity. This area is home to unique species and a rich cultural tapestry of around 220 ethnic communities that maintain a harmonious relationship with nature. Local governance has preserved tribal identities and traditional practices, which contribute to biodiversity conservation. However, extreme weather events linked to climate change are threatening the livelihoods of these communities, leading to increased urbanization, abandonment of agricultural practices, and loss of traditional knowledge. To combat these challenges, the UNDP has launched the North-East India Biocultural Initiative (NEBI) under the ICCA-GSI, aiming to empower Indigenous and ethnic communities by revitalizing traditional knowledge and promoting ecosystem-based solutions that align with their cultural and ecological systems.

Cultivating solutions against climate change in Central America

In the countries of the Central American Integration System (SICA) lies the Dry Corridor, considered one of the most vulnerable ecoregions to climate variability and change. It is characterized by long periods of drought with rising temperatures or intense rainfall. People dependent on agriculture are the most affected socially, economically, and environmentally, with serious consequences for their food security and nutrition. The Food and Agriculture Organization of the United Nations (FAO) works with Central American governments to promote innovative solutions that support the work, leadership, and knowledge of women and men in preparing, alongside their rural communities, to face climate change, the degradation of natural resources, and limited access to technology and innovation — all key to achieving inclusive rural development, thus strengthening resilience and improving livelihoods.
