Jornal Do Brasilia - UN tries anew to finish treaty protecting the high seas

After more than 15 years of formal and informal talks, this is the third time in less than a year that negotiators have converged on New York in what, yet again, is supposed to be a final and conclusive round.

But as the talks, set to run through March 3, opened on Monday cautious optimism appeared to be taking hold.

"I hope we've come together here with a will to get us to the finish line," said conference chair Rena Lee as the talks began, adding that "an agreement that is universal, that is effective, that is implementable and that is futureproof is within our reach."

An historic agreement reached in Montreal in December during the UN's COP15 conference on biodiversity is helping to fuel the sense of promise.

Countries then committed themselves to protecting 30 percent of the world's lands and seas by 2030 -- a nearly impossible challenge if it fails to include the high seas, of which only about one percent is now protected.

"We're optimistic the COP15 biodiversity agreement will provide the shot in the arm needed for governments to get this important agreement over the line," Pepe Clarke, Oceans Practice Leader for WWF International, said in a press release.

The high seas begin at the border of countries' Exclusive Economic Zones, which extend up to 200 nautical miles, or 370 kilometers, from coastlines. They thus fall under the jurisdiction of no country.

While the high seas comprise more than 60 percent of the world's oceans and nearly half the surface of the planet, they have long drawn far less attention than coastal waters and a few iconic species.

But with no borders at sea, there is "just one ocean, and a healthy ocean means a healthy planet," Nathalie Rey of the High Seas Alliance told AFP. Her group includes about 40 NGOs.

Ocean ecosystems, threatened by climate change, pollution and overfishing, create half the oxygen we breathe and limit global warming by absorbing much of the carbon dioxide emitted by human activities.

- 'Last chance' -

Despite the optimism of some observers and the informal talks that have taken place since the last formal session in August, the oceans' defenders warn that failure is still possible.

"If they do fail again, I think it really calls into question the process itself," Liz Karan of Pew Charitable Trusts told AFP.

Laura Meller of Greenpeace Nordic warned that "we're already in extra time."

"These talks are one final chance to deliver. Governments must not fail."

The draft treaty, full of parenthetic clauses and multiple options, reflects the long list of contentious issues still on the table.

While the principle of creating marine protected areas is a core part of the mandate, delegations remain divided on how exactly these sanctuary zones would be established.

There is also no agreement on how to assess the environmental impact of activities such as mining in the high seas.

And debate continues on how to divide eventual profits from the collection -- by pharmaceutical, chemical or cosmetic manufacturers, for example -- of newly discovered marine substances.

Developing countries, without the means to afford costly research, say they fear being left aside while others make windfall gains.

And during the August session, observers accused rich countries, notably European Union member states, of making only a last-minute gesture in this direction.

On behalf of ocean defenders around the world, actor and activist Jane Fonda plans on Monday to present the conference's president, Rena Lee, with a petition signed by five million people calling for a "strong" treaty.

Given the complexity and vast reach of a treaty and the need to work with other agencies with varying authority in parts of the ocean, strong language is vital, they say.

For even with an accord, they add, the devil is in the details.
