World Post Day: Innovate to recover 

World Post Day (9 October) was declared by the 1969 Universal Postal Congress in Tokyo to mark the anniversary of UPU’s creation in 1874. This year’s observance highlights the postal sector’s ability to adapt to new realities, taking on new roles founded on digitalization, e-commerce and financial services. UN Secretary-General António Guterres emphasizes that beyond just a service, “the vast postal network – involving millions of workers moving billions of pieces of mail through hundreds of thousands of post offices – is woven into our societies, connecting communities the world over.”

Life Below Water: coral reefs

Coral reefs occur in more than 100 countries and territories. They support at least a quarter of marine species and underpin the safety, coastal protection, wellbeing, food and economic security of hundreds of millions of people. However, coral reefs are among the most vulnerable ecosystems on the planet due to global threats from climate change and ocean acidification, and local impacts from land-based pollution, marine pollution, overfishing and destructive fishing practices. A new report examines the status of the world's coral reefs over the last 40 years.

On My Mind: children’s mental health

The COVID-19 pandemic has raised concerns about the mental health of a generation of children. But the pandemic may represent the tip of a mental health iceberg – an iceberg we have ignored for far too long. The State of the World’s Children 2021 examines child, adolescent and caregiver mental health. It focuses on risks and protective factors at critical moments in the life course and delves into the social determinants that shape mental health and well-being. It calls for commitment, communication and action as part of a comprehensive approach to promote good mental health for every child.

World Mental Health Day 2021

The COVID-19 pandemic has had a major impact on people’s mental health. Some groups, including health and other frontline workers, students, people living alone, and those with pre-existing mental health conditions, have been particularly affected. And services for mental, neurological and substance use disorders have been significantly disrupted. Yet there is cause for optimism. Governments from around the world recognize the need to scale up quality mental health services at all levels. Mental health care for all: let’s make it a reality

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.

The UN’s 75th anniversary in 2020 arrived at a time of great upheaval and peril. To secure a world where everyone can thrive in peace, dignity and equality on a healthy planet we need a multilateral system that is inclusive, networked and effective.

In less than a year, scientists made multiple vaccines to help combat the Covid-19 pandemic. However some countries are missing out as they do not have equitable access to the vaccines. WHO encourages we work together, to produce and deliver doses to vaccinate 70% of every country by the middle of 2022. But we are in a race against time and we all must do more, faster. No one is safe until we’re all safe. #VaccinEquity

Shifting gears for sustainable transport

A farmer carrying produce to local markets, a ship being loaded with medical supplies, a child seated on a school bus – the movement of people and goods, whether local, trans- or intercontinental, shapes sustainable development. Sustainable transport – with its objectives of universal access, enhanced safety, reduced environmental and climate impact, improved resilience, and greater efficiency – is the focus of the 2nd Global Sustainable Transport Conference.

Educators and the changing world of education and work

Effective lifelong learning and quality education for all is essential for a better future of work. If teachers, trainers and support workers are to fill this need they will need to master new technologies and learning techniques and receive support to deal with their expanded responsibilities. ILO works to increase support for education workers.

Making alternative Indigenous food markets mainstream

It has since grown into a tribal producer company that uses organic production and sustainable harvests of local crops, has been awarded the UNDP’s Equator Prize 2021 along with nine other Indigenous peoples and local communities. The Equator Prize recognizes effective and scalable nature-based solutions to our world’s most pressing environmental, food and economic dilemmas.

How Africa is using nature to adapt to climate change

Preparing for the impacts of climate change, known as climate change adaptation, will be key for African nations. Adaptation – the reduction of vulnerability to climate change by increasing the ability to absorb impacts and remain resilient – is a key pillar of the Paris Agreement. UNEP’s Adaptation Gap Report 2020 found advancements in planning and implementation adaptation projects, yet huge gaps remain, especially in finance for developing countries. UNEP shows us how eight communities in Africa are using nature-based solutions to adapt to a changing world.
