‘A missed opportunity’

UN member states ended two weeks of negotiations without a treaty to protect biodiversity in the high seas, an agreement that would have addressed growing environmental and economic challenges.

After 15 years, including four prior formal sessions, negotiators have yet to reach a legally binding text to address the multitude of issues facing international waters -- a zone that encompasses almost half the planet.

"Although we did make excellent progress, we still do need a little bit more time to progress towards the finish line," said conference chair Rena Lee on Friday.

It will now be up to the UN General Assembly to resume the fifth session at a date still to be determined.

Many had hoped the session, which began on August 15 at the United Nations headquarters in New York, would be the last and yield a final text on "the conservation and sustainable use of marine biodiversity beyond national jurisdiction," or BBNJ for short.

One of the most sensitive issues in the text revolved around the sharing of possible profits from the development of genetic resources in international waters, where pharmaceutical, chemical and cosmetic companies hope to find miracle drugs, products or cures.

Such costly research at sea is largely the prerogative of rich nations, but developing countries do not want to be left out of potential windfall profits drawn from marine resources that belong to no one.

The high seas begin at the border of a nation's exclusive economic zone (EEZ) -- which by international law reaches no more than 200 nautical miles from its coast -- and are under no state's jurisdiction.

Sixty percent of the world's oceans fall under this category.

And while healthy marine ecosystems are crucial to the future of humanity, particularly to limit global warming, only one percent of international waters are protected. One of the key pillars of an eventual BBNJ treaty is to allow the creation of marine protected areas, which many nations hope will cover 30 percent of the Earth's ocean by 2030.

But delegations still disagree on the process for creating these protected areas as well as how required environmental impact assessments will be implemented before new high seas activity begins.

"What a missed opportunity...", tweeted Klaudija Cremers, a researcher at the IDDRI think tank.

Laura Meller, of Greenpeace's Protect the Oceans campaign, said: "Time has run out. Further delay means ocean destruction. We are sad and disappointed. While countries continue to talk, the oceans and all those who rely on them will suffer."
