Mise à jour: 08 Juin 2021

Covering more than 70% of the Earth's surface, oceans are essential to human lives and livelihoods. World Oceans Day is the occasion to raise awareness of the benefits humankind derives from the ocean and our individual and collective duty to to use its resources sustainably. Discover more about the vital role oceans play in our lives and the work that is being done in Geneva to preserve marine environments and foster a more sustainable blue economy.

Celebrating the Oceans

The ocean is our planet’s largest ecosystem. It stabilizes climate, stores carbon, nurtures unimaginable biodiversity, and directly supports human well-being through food and energy resources, as well as by providing cultural and recreational services. Unfortunately, despite improved management and conservation actions, the UN Second World Ocean Assessment, launched in April 2021, found that pressures from many human activities continue to degrade the ocean and destroy essential habitats. As the world population will reach an estimated 9 billion people by 2050, impacts on the ocean associated with human activities will increase.

World Oceans Day, celebrated each year on 8 June, reminds every one of the major role the oceans have in everyday life. The purpose of the Day is to inform the public of the impact of human actions on the ocean, develop a worldwide movement of citizens for the ocean, and mobilize and unite the world’s population on a project for the sustainable management of the world’s oceans.

The Ocean: Life and Livelihoods” is the theme for World Oceans Day 2021, as well as a declaration of intentions that launches a decade of challenges to get the Sustainable Development Goal 14, “Conserve and sustainably use the oceans, seas and marine resources”, by 2030.

UN Decade of Ocean Science for Sustainable Development

This year, World Oceans Day will see the launch of the the UN Decade of Ocean Science for Sustainable Development (2021-2030). The Ocean Decade will provide an opportunity for nations to work together to generation the global ocean science needed to support the sustainable development of our shared ocean.

The Ocean Decade provides will to create a new foundation across the science-policy interface to strengthen the management of our oceans and coasts for the benefit of humanity, and strengthen the international cooperation needed to develop the scientific research and innovative technologies that can connect ocean science with the needs of society.

It will also contribute to the UN processes protecting the ocean and its resources, such as the SAMOA Pathway, the United Nations Convention for the Law of the Sea, the post-2020 framework for the Convention on Biological Diversity and the Sendai Framework for Disaster Risk Reduction.

The Ocean Decade requires the engagement of many different stakeholders to create new ideas, solutions, partnerships and applications, these include: scientists, governments, academics, policy makers, business, industry and civil society.

The Importance of Oceans

The ocean covers over 70% of the planet. It is our life source, supporting humanity’s sustenance and that of every other organism on earth. The ocean produces at least 50% of the planet’s oxygen, it is home to most of earth’s biodiversity, and is the main source of protein for more than a billion people around the world. Not to mention, the ocean is key to our economy with an estimated 40 million people being employed by ocean-based industries by 2030.

Even though all its benefits, the ocean is now in need of support. With 90% of big fish populations depleted, and 50% of coral reefs destroyed, we are taking more from the ocean than can be replenished. To protect and preserve the ocean and all it sustains, we must create a new balance, rooted in true understanding of the ocean and how humanity relates to it. We must build a connection to the ocean that is inclusive, innovative, and informed by lessons from the past.

Stopping Plastic Pollution

Plastic pollution is found everywhere from the Mount Everest to the Mariana Trench, and the deepest part of the oceans.  Of the approximately 275 million metric tons of plastic waste produced annually, up to 12 million tons leak into oceans, wreaking havoc on livelihoods and ecosystems . The result is an estimated $13 billion in annual environmental damage to marine ecosystems.

In 2017, the UN Environment Assembly established the Ad Hoc Open-Ended Expert Group (AHEG) on Marine Litter and Microplastics. The expert group concluded its work ahead of UNEA-5.1 in February 2021 and has put forward a series of possible policy responses to reduce plastic pollution in marine environments. Attention is now turned to UNEA-5.2 in February 2022, as many governments, civil society and business organisations are calling for the establishment of an international treaty on plastic pollution.

Ending Overfishing

More than 820 million people depend on fisheries and aquaculture for food, nutrition, and income (FAO, n.d.). But the ability of the world’s fisheries to provide jobs and nutrition is being threatened by an unprecedented crisis of overfishing and improper resource management.  The Second World Ocean Assessment revealed that, while fisheries management is improving in many regions, a third of global stocks are still overfished.

Efforts to reverse the trend are thus essential to secure livelihoods and food security and protect biodiversity. Scientific findings indicate that 98% of currently overfished stocks could recover by the middle of this century if  managed properly. At the global level, negotiations on fisheries subsidies, which can contributes to overfishing, are ongoing at the World Trade Organisation (WTO) in order to achieve SDG 14.6. On World Oceans Day 2021, WTO Director-General Ngozi Okonjo-Iweala and Ambassador Santiago Wills, chair of the Negotiating Group, reiterated their call to governments to conclude negotiations and reach an agreement at the ministerial meeting in July 2021

Fostering Sustainable Blue Economy

The oceans support the livelihoods of more than 3 billion people. The value of the oceans economy sectors, such as fisheries, maritime transport, coastal tourism, off-shore energy and marine bio prospecting, has been estimated at about 3 trillion USD annually. Worryingly, the current mode of operating of oceans economic activities is no longer sustainable. The natural assets that the blue economy depends on are fast eroding under the pressure of human activities.

Therefore, we need to diversify towards economic activities that will have a lower impact on ecosystems, while sustaining livelihoods and stimulating job creation. It’s possible to combine production from the ocean while protecting its economic, social and environmental value for the future. The UN Decade of Ocean Science will be an opportunity to maximize the benefits of effective science-based management of our ocean space and resources.

Role of Geneva

Various Geneva-based organizations or secretariats – listed below in alphabetical order – work actively to protect and restore the oceans and promote a sustainable blue economy. UN system’s engagement with oceans-related issues also goes beyond Geneva, with organizations around the world involved, such as the UN Environment Programme (UNEP) and the Food and Agriculture Organization (FAO).

This is crucial in the fight against Illegal, Unreported and Unregulated fishing practices. UN/FLUX is now implemented in EU member states, with preparations underway to control fish stocks in the North-East Atlantic.

World Economic Forum (WEF)

The WEF is an international organization for public-private cooperation shaping shape global, regional and industry agendas. Its work on oceans aims to shape a new ocean economy, addressing the interlinkages between oceans, climate change, biodiversity, technologies, governance and more. The WEF convenes the Friends of Ocean Action – a coalition of over 65 ocean leaders who are fast-tracking solutions to the most pressing challenges facing the ocean. It also hosts the Global Plastic Action Partnership which supports the transition to a circular plastics economy.

World Meteorological Organisation (WMO)

As a specialized agency of the United Nations, WMO is dedicated to international cooperation and coordination on the state and behaviour of the Earth’s atmosphere, its interaction with the land and oceans, the weather and climate it produces, and the resulting distribution of water resources.

World Trade Organisation (WTO)

The WTO is the only global international organization dealing with the rules of trade between nations. Since 2001, WTO members are negotiations rules to eliminate subsidies for illegal, unreported and unregulated fishing and to prohibit subsidies that contribute to overcapacity and overfishing, with special and differential treatment for developing and least developed countries.
