Protecting Ocean Life on the High Seas
The high seas make up about two-thirds of the world’s ocean, covering the vast expanses beyond the jurisdiction of any country.

Research has shown that the high seas hold some of the largest reservoirs of biodiversity on Earth, supporting abundant fisheries, providing migratory routes for whales and sharks and harboring remarkable ecosystems such as deep-water corals and other majestic marine life.

But the high seas lack consistent and effective oversight. A patchwork of rules and regulations provides little to protect marine life from commercial activities such as fishing, oil and gas exploration and deep-sea mining, all of which are expanding.

The designation of marine protected areas and reserves—the equivalent of national parks at sea—would be a good first step toward providing the needed protection. In an area that is part of the global commons, the challenge starts with establishing an international legal instrument—the biodiversity beyond national jurisdiction treaty—to create high seas reserves. This treaty can fill critical governance gaps and ensure effective management of high seas marine resources.

Pew is working to meet that challenge, primarily though the United Nations, which has committed to negotiate an international treaty to protect the high seas.

The high seas—the ocean area beyond the jurisdiction of any country—covers two-thirds of the ocean and is home to a wealth of biodiversity. And yet only 1% of the high seas is protected. Illegal fishing, overfishing, new and emerging activities such as geoengineering, and climate change are among the many threats to high seas marine life.

Issue Brief

Les membres des Nations Unies travaillent actuellement sur un traité visant à préserver et exploiter de manière durable la biodiversité des zones ne relevant d’aucune juridiction nationale, et notamment des eaux internationales que l’on désigne généralement sous le terme de « haute mer ».
