UN talks begin on a new law to save our oceans Updated for 2026





The United Nations has resolved to modernise international law on the sustainable use of the high seas and their wildlife.

The move could lead to new laws to address many of the oceans most severe problems, including measures to combat over-fishing and illegal fishing, the regulation of ‘by catch’ by fishing vessels, and the conservation of endangered species.

Other issues on the agenda include the protection of the seabed from deep sea mining, ocean acidification from rising levels of carbon dioxide in the atmosphere, marine biodiversity prospecting, regulation of offshore oil and gas prospecting, and the clean up of vast floating islands of plastic waste.

Following the decision by the United Nations Informal Working Group on Biodiversity Beyond National Jurisdiction (BBNJ), negotiations will now begin for a new international agreement for the sustainable use and conservation of marine biodiversity in the high seas.

Encouraging and historic

The decision was welcomed by David Miliband, Co-chair of the Global Ocean Commission (GOC), who had himself addressed delegates at the BBNJ meeting. It was “encouraging to see the UN agreeing to take action”, he said.

“This was one of the main demands identified by the Global Ocean Commission. I’m glad the message is getting across. The consensus reached last week will be remembered as a milestone in the modernisation of ocean governance.”

GOC Commissioner Robert Hill, who was the first Chairperson of the BBNJ when it was formed in 2006, called last week’s decision “historic”, adding:

“As always with UN processes, the work is far from over. First, we have to ensure the consensus recommendation is not undermined when it goes before the General Assembly in a few months and, second, it will be important to monitor closely the treaty negotiation – including the Preparatory Committee process and ultimately the international conference.”

Last year the GOC called for a new Implementing Agreement under the UN Convention on the Law of the Sea (UNCLOS) to prioritise ocean health and resilience, restore ocean productivity, guard against irresponsible, inefficient and wasteful exploitation, and allow for the creation of high seas marine protected areas (MPAs).

Such an agreement would extend governance to the 64% of the global ocean – and 45% of the planetary surface – that lies outside national jurisdiction, and provide a mechanism to conserve valuable high seas services such as carbon sequestration, worth between US$74 and US$222 billion annually, currently in jeopardy.

Time to end the high seas ‘failed state’

“The high seas are like a failed state , said Miliband. Poor governance and the absence of policing and management mean valuable resources are unprotected or being squandered. The high seas belong to us all. We know what needs to be done but we can’t do it alone. A joint mission must be our priority.”

The GOC’s call was relayed and supported by more than 285,000 citizens from 111 countries, who signed a petition that was delivered to the UN Secretary General at the opening of the current Session of the UN General Assembly in September last year.

The BBNJ was mandated by the Rio+20 2012 Earth Summit to address the governance and conservation of the high seas – the portion of the ocean beyond a country’s 200-mile Exclusive Economic Zone. These areas beyond national jurisdiction represent 64% of the ocean’s surface, and 45% of our entire planet.

How small rodents in the Arctic affect birds in New Zealand Updated for 2026

The complicated predator-prey interactions are one of the most fascinating fields in ecology. They have been studied for decades, and the more we learn, the more surprising and unpredicted stories that we find. For me, finding that small rodents (lemmings) in the high Arctic may affect the populations of waders on the coast of Australia, New Zealand or South Africa was a real amazement.

Lemming populations have been known to show 3-5 years cycle, driven by either top-down or bottom-up control. In the Early View paper “Loss of periodicity in breeding success of waders links to changes in lemming cycles in Arctic ecosystems”, we have studied the interactions between the breeding success of high-Arctic nesting migratory shorebirds and lemming abundance, as they were suggested to be linked via the ‘alternative prey hypothesis’: In years of low lemming abundance, their predators, mainly Arctic fox, would switch to alternative prey, including chicks and eggs of shorebirds. In light of the large amount of evidence that lemming cycles have now changed and even disappeared in some parts of the Arctic, we found that the breeding success of these migrants used to follow the cycles of lemmings, but these cycles have too started to disappear, suggesting a cascading effect of changes in lemming cycles.

The reason for these changes in lemming cycles is still not entirely known. One possible explanation is that climate change caused alteration of the snow structure which is a crucial hiding and feeding place for lemmings during winter. It might also be the natural tendency of populations in nature to go in and out of cycle. As shorebirds are known to consume considerable amount of benthic invertebrates, these changes in lemming cycle in the high Arctic potentially not only affect shorebird populations in the other side of the worlds, but also have a far-reaching cross-systems consequences on the ecosystem on the southern hemisphere.
