In Rio de Janeiro, Brazil, an international symposium is being held from October 10 to 12, bringing together scientists, authorities, and civil society organizations from multiple countries to discuss the strategies for implementing the first global agreement on protecting the high seas. This event marks the third edition of the symposium and is particularly significant as it coincides with the enforcement of the Marine Biodiversity Beyond National Jurisdiction (BBNJ) treaty, commonly known as the High Seas Treaty, which recently came into effect following nearly two decades of negotiations.

The high seas, which cover almost half of the Earth's surface, previously lacked specific and comprehensive legal protection. The BBNJ treaty, which has the standing of international law, establishes guidelines for the conservation and sustainable use of marine biodiversity in areas beyond 200 nautical miles (370 kilometers) from coastlines. This development not only reflects the increasing recognition of the need to safeguard our oceans but also the collective desire for a more sustainable approach to ocean management as human activities continue to put pressure on marine ecosystems.

Despite the treaty now being in force, challenges remain in its implementation, highlighting the need for ongoing dialogue and collaboration among participant nations. The symposium provides a platform for sharing ideas and best practices, as well as addressing the necessary steps to ensure that the high seas are adequately protected. Strengthening these discussions is essential for the successful achievement of the treaty's objectives and the long-term health of our planet's oceans, which play a crucial role in regulating global climate and supporting diverse marine life.
