Chile Creates Ocean Reserve Network the Size of Nigeria

Chile has established one of the world's largest marine protected areas, signing a presidential decree to safeguard 337,000 square kilometers of ocean around the Juan Fernández archipelago — an area roughly the size of Germany. Combined with two existing reserves, Chile now protects 899,268 square kilometers of ocean, equivalent to the entire land area of Nigeria.

The protected waters support diverse marine life including whales, seabirds, and the Juan Fernández fur seal, a species once thought extinct that has recovered through conservation efforts. The reserve network showcases how ambitious local conservation can drive global leadership in ocean protection.

Chile now has over 50% of its territorial waters under protection, far exceeding the international target of protecting 30% of oceans by 2030 that was agreed by 190 nations in 2022. This positions Chile as a global leader in marine conservation at a time when ocean ecosystems face unprecedented pressure from climate change, overfishing, and pollution.
