75 years of connecting the world

International Civil Aviation Day, 7 December, commemorates the signing in 1944 of the Convention on International Civil Aviation. Known as the ‘Chicago Convention,’ this landmark agreement established the core principles governing international transport by air and led to the creation of the International Civil Aviation Organization (ICAO), in charge of setting civil aviation standards and policies in support of a safe, efficient, secure, and environmentally responsible civil aviation sector. This year ICAO marks 75 years of connecting the world.

Stand up for human rights

We need to stand up for our rights and those of others. We can take action in our own daily lives, to uphold the rights that protect us all and thereby promote the kinship of all human beings. Wherever there is discrimination, we can step forward to help safeguard someone's right to live free from fear and abuse. The UN Human Rights Office upholds values that are the roots of peace and inclusion. Join us. It starts with each of us. This Human Rights Day and every day stand up for human rights.

A staff member’s reflections on peacekeeping deployment

Like many prospective staff members, Lonjezo Hamisi envisioned serving at some point in his career in a region beset by war, injustice, poor governance and poverty, with the hope of easing the plight of the people most in need on the ground. He got his chance when he was posted to the United Nations-African Union Hybrid Operation in Darfur (UNAMID), where he served as Special Assistant to the Mission Chief of Staff.

Bolivia’s sweet new industry

In the Bolivian countryside an appetizing industry has taken off, bringing a sweet new business to rural communities: chocolate production. When it comes to chocolate, Bolivia might not be the first place you think of yet - but thanks to the combined efforts of FAO, smallholder farming collectives and indigenous producers, it soon will be. Over the past five years, Bolivia’s chocolate producers have been quietly racking up the achievements and gaining global recognition for the quality of their products

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:

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.

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.

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.

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.

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.

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).

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.

Women and girls represent half of the world’s population and, therefore, also half of its potential. Gender equality, besides being a fundamental human right, is essential to achieve peaceful societies, with full human potential and sustainable development.

While global poverty rates have been cut by more than half since 2000, one in ten people in developing regions still lives on less than US$1.90 a day — the internationally agreed poverty line, and millions of others live on slightly more than this daily amount.

Still, many invalid opinions hold back millions of people with disabilities globally from entering and progressing in the workplace. Oftentimes, people with disabilities continue to be dismissed, judged or belittled. Mostly, these invalid opinions and comments aren’t even intended to be malicious. They’re well-meaning, but miss the mark, because the person making them assumes the person they’re addressing is weaker, more vulnerable, or less likely to succeed professionally and in life in general because of their disability. The #invalidopinions campaign puts a spotlight on a number of individuals defying these invalid opinions everyday. Your opinion matters. Make sure it’s valid.

A Teenager Takes on Restrictive Exam Rules, and Wins!

Maria Alexandrova became Bulgaria's first adolescent living with cerebral palsy to take the prestigious Cambridge Assessment in English. Her advocacy led to the local exam centre agreeing to change the timing of the test and let her use a computer. These changes pave the way for other students with physical challenges to take the exam, boosting their chances to go to university, find work and live independent lives. Maria's story is part of the UNICEF Europe and Central Asia Office's ongoing look – as the world marks the 30th anniversary of the UN Convention on the Rights of the Child – at young heroes using their voice to protect and promote the rights of their peers.

Celebrating the ‘Power and Potential’ of Volunteerism

Volunteerism opens doors and impacts peace and development throughout local communities as well as on a national and global level, according to the chief of UN System Affairs and New York Office of UN Volunteers (UNV). Particularly for those excluded, it provides a concrete way to “impact their own lives and play a constructive role in their communities," Naoual Driouich said, in an interview with UN News ahead of International Volunteer Day.

She knows her way around the UN system, having previously served with UN Women and the UN Development Programme, UNDP, in Iraq, Yemen and other hotspots, seeing “first-hand” the difference volunteering can make.

Co-operation for Co-existence

There are less than 400 Spoon-billed Sandpiper (SBS) worldwide. The critically endangered bird is a small migratory wader that breeds in north-eastern Russia and winters in South and South-East Asia; small numbers are recorded in the inner Gulf of Thailand. The good news is mudflats in Khok Kham salt-farming community are rich in food resources for SBS. Salt farming methods have created ecosystems particularly well-suited for feeding and sheltering migratory shorebirds. The bad news is there are just 28 salt-farmers left in the Khok Kham. If salt farming disappears, it will render the return of SBS unlikely. The recognition of symbiosis between bird and farmer is key to preserving biodiversity via sustainable development.

Bridging the HIV Divide

"At first they used to say 'these things are for older people; you can't be here talking.' Now they have started getting used to it and started talking to me,” Reginalda Elias (16) said. Globally, an estimated 6,000 young women and girls become infected with HIV each week. This is particularly stark in Angola where new HIV infections among women aged 15-24 are more than double those of young men. The end of the 27-year civil war in 2002 heralded a new beginning. But widespread inequalities, poverty and a climate change-induced drought in the Eastern and Southern provinces have pushed people’s coping mechanisms to the limit. Angola is one of the few countries in Africa where new HIV infections and AIDS-related deaths have risen in the last 10 years. But the next generation of female activists are fighting back.

What is it like to live with a disability when you’re displaced?

Bawk Ra from Myanmar lost the ability to walk when she was 5. Then she lost her home. With a smartphone, training and help from her family, she captured her life on camera. "I wish someone could understand my worries." As a result of ongoing conflict in Myanmar’s Kachin State, more than 107,000 people live in camps for the internally displaced. Many camps have few livelihood opportunities and limited access to health care and education. This photography project, run by UNHCR and Yangon Photo Festival, gives people like Bawk Ra the skills to share their own stories. Bawk Ra has since won an award for these photos – and a brand new Canon camera.

Climate Change and Health in Pictures

“The Marathwada region in India was hit by the worst drought in 40 years, affecting nearly nine million farmers and their families. With taps and wells running dry, drinking water was brought in with tankers - 17 liters per person, once every 14 days.” WHO's message: implement and monitor national policies that protect the health of your citizens from climate change. This is one of the five key WHO messages on climate and health, captured by five powerful images.
