Briefings

Global mangrove cover increased by 477 square kilometers between 1985 and 2025, marking a significant turnaround after decades of decline. This 0.3% net gain over four decades was driven by restoration efforts and stronger protections, as confirmed by the latest Global Mangrove Watch data. Researchers used 10-meter satellite imagery and machine learning to map changes across 108 countries over a 39-year period, with the new assessment spanning 1985 to 2024.

Key points

• Global mangrove cover increased by 477 square kilometers (184 square miles) between 1985 and 2025, representing a 0.3% net gain over four decades.
• The new assessment covers 108 countries and utilized 10-meter resolution satellite imagery and machine learning to track changes since 1985.

Context and limitations

Data coverage is limited to 108 countries and spans a 39-year period from 1985 to 2024; previous versions tracked changes since 1996 covering only about 24 years.
