The treasures of the high seas – 50% of the planet – are up for grabs and undefended: some marine life could be disappearing before it is even discovered. With fishing, mining and pollution encroaching ever further and deeper into the Ocean, the existing legal and governance framework is out of date and out of its depth. The current process to negotiate a new high seas treaty must lead to a robust agreement fit for guarding Ocean life against 21st century perils, and for the benefit of all.
COMMON HERITAGE, COMMON RESPONSIBILITY
- The high seas are the international waters covering over two thirds of our Ocean that are owned by everyone but managed by no-one. That’s nearly 50% of the planet’s surface area and because of the depth of the Ocean, if you think in 3-dimensions, it is so much more!
- The high seas are part of the global commons and governed collectively by all nations. Once thought to be barren and devoid of life, it is now known that the high seas are one of the largest reservoirs of biodiversity on Earth.
- Many marine species, such as whales, tunas, and sharks, spend much of their lives on the high seas, migrating along the highways and byways of great Ocean basins from feeding to spawning grounds, and back again.
- Other species spend their entire lives in the high seas, living and breeding along the mighty submerged mountain ranges that span the global Ocean.
- Discoveries made in ancient, deep-sea coral fields and on seamounts teeming with life yield potentially life-saving medicines and enhance our understanding of global biodiversity. Yet we know more about the surface of the Moon than we do about the deep-sea bed of the high seas.
- More people have ventured into outer space than to the deepest depths of our Ocean. At its deepest point, the Ocean is nearly 11 km deep (over 2 km deeper than Mount Everest is high), yet the deep sea seems a whole different world away.
- Only 0.0001% of the deep seafloor has so far been studied and it is estimated that millions of species living there are yet to be discovered, as well as potential cures for fatal diseases.
- The high seas provide critical ecosystem services for our planet – from fisheries to climate regulation. As examples, current estimates of the economic value of carbon storage by the high seas range from US$74 billion to US$222 billion per year while high seas fisheries raise up to US$16 billion annually in gross catch.
- Increasing impacts from human activity, continue to negatively affect biodiversity on the high seas. For example, fish stocks are in trouble because dwindling stocks nearer to shore mean that vessels are going further and deeper looking for fish. Destructive fishing practices, such as bottom trawling, and illegal fishing are threatening high seas marine life. And new and emerging unregulated activities are adding another layer of concern. Combine these threats with the impacts of a changing climate, and you have a very unhealthy cocktail that is poisoning our blue planet.
- So why has so little been protected? Firstly, the high seas are not the responsibility of any one State, but belong to all of us. And whilst it is pretty straightforward to protect areas within national waters, for most of the high seas there are no clear rules, which has meant that for too long protecting high seas marine life has been placed on the “too difficult pile”.
- The United Nations Law of the Sea Convention (UNCLOS), an international treaty that many call ‘the Constitution of the Ocean’ was negotiated through the 1990s to determine which marine areas States have jurisdiction over, and which are areas of international responsibility. Since then, several agreements have been made to regulate specific activities, like seabed mining and fishing for highly migratory and straddling fish stocks. Under these treaties, particularly for fishing, a plethora of organizations have been set up to manage different types of fishing or specific species on the high seas.
- It is an expensive, ungainly and ineffective system that needs fixing. And it still leaves major gaps in coverage. With a focus on organizing States around extracting life from the Ocean, inadequate attention has been focused on organizing to keep marine life in the sea.
- Currently, there is no legal mechanism with which to establish fully protected marine areas in most parts of the high seas, no mechanism to undertake environmental impact assessments and no agreement for access and benefit sharing of marine genetic resources in areas beyond national jurisdiction.
- However, that is all about to change! In 2017, the world’s governments at the United Nations finally agreed, after more than 10 years of discussion, to start negotiations to develop a treaty text that protects the biodiversity on the high seas.
WHAT NEEDS TO HAPPEN?
- For the Ocean to carry on functioning as a key life-support system, providing food, jobs and oxygen to name just a few of the things we term economic “services”, we cannot ignore the 2/3 of the Ocean that makes up the high seas (as this short film shows).
- Over the past decade, negotiators at the United Nations have been discussing what best to do to protect marine life in the high seas.
- A breakthrough was reached on the 24th December 2017, when governments at the United Nations formally agreed through a UN resolution to negotiate a new treaty on high seas biodiversity protection. Negotiations will start in September 2018, and are expected to last into the first half of 2020.
- This agreement will include the use of area-based management tools like marine protected areas and reserves, the need for prior environmental impact assessments to assess potential harm, the access to and fair sharing of marine genetic resources, as well as capacity building and the transfer of marine technology. The treaty should also incorporate modern environmental governance principles such as requirements for transparency and incorporate ecosystem-based management and the precautionary principle.
- Given what we now know about the impacts of climate change on the Ocean and the critical role of a healthy Ocean as a carbon sink and source of Oxygen, the sooner this agreement gets finalized and enters into force, the better.
- This would be the first global treaty process focused specifically on protection of marine biodiversity for life in the Ocean beyond national boundaries (the high seas and its seabed floor below).
- Securing the health of the global Ocean is critical if we want to build resilience to change and secure the health of the world’s biosphere for future generations. We need government leaders to encourage their negotiators to work quickly for a strong agreement to secure the health of the global Ocean and meet the ambition of the Paris climate deal.
- Now is the time for a robust international agreement that reflects the realities of the 21st century and turns the tide so that instead of destroying life in the sea, we revitalize and rebuild it.
