On the beaches of Mombasa, where fishing boats have bobbed for generations, something larger than any single vessel took shape this June: a $6.4 billion wave of commitments to protect the world's oceans. The Our Ocean Conference—held for the first time ever in Africa—brought 6,000 delegates to Kenya's Indian Ocean coast, where they witnessed more than 300 voluntary pledges aimed at safeguarding marine life from overfishing, pollution and climate change.
The gathering marked a milestone for a continent where coastal communities have long depended on healthy seas but where ocean conservation pledges have historically lagged behind those from wealthier nations. Kenya itself stepped forward with over 40 commitments backed by more than $1 billion in financing, targeting expanded marine protected areas, improved fisheries monitoring, climate finance and the development of sustainable coastal economies.
"We did not come to Mombasa to add our names to a longer list of promises. We came to turn the tide," said Kenya's President William Ruto at the closing ceremony on June 18. His words echoed the conference's central challenge: converting pledges into verified progress. Since the first Our Ocean Conference launched in 2014, more than 3,200 commitments totaling $176 billion have been made—and roughly 85 percent of those have been fulfilled or are actively underway, a track record that lends credibility to the latest announcements.
With the global deadline for protecting 30 percent of the world's oceans now less than five years away, attention focused sharply on national commitments. Senegal pledged to double its marine protected area network by 2030. Indonesia said it would designate 7,000 square kilometers of new protected waters this year. Tanzania committed to establishing a 2,500 square kilometer marine protected area in Kilwa district by 2028, and to work with Kenya on a cross-border conservation zone spanning coral reefs, mangroves and seagrass beds. On Africa's western shore, Gambia and Guinea-Bissau agreed to advance at least two shared marine protected areas.
Further afield, Portugal announced plans for the D. Carlos Marine Reserve, a 173,000 square kilometer expanse that would raise its protected waters from 19 to 25 percent. Brazil promised to expand its marine protected estate by 240,000 square kilometers over five years and to pursue a high seas protected area in the Southern Atlantic under the U.N.'s High Seas Treaty, which entered into force earlier this year.
For Arthur Tuda, executive secretary of the Tanzania-based Western Indian Ocean Marine Science Association, the numbers matter less than the quality of protection. "We continue to create more marine protected areas. That's a good thing, but I think we are now also more strongly focused on quality," he told Mongabay. As delegates departed Mombasa, that tension—between expansion and effectiveness—remained the central question for an ocean under mounting pressure.
