Mangrove forests are quietly regrowing worldwide, reversing decades of loss, new satellite study finds

A new study published in the journal Science used satellite data from the 1980s to 2023 to track global mangrove cover. The researchers found that natural regrowth has largely offset the historic decline caused by shrimp farming, urban expansion, and agriculture. Mangrove losses have slowed significantly, and in many regions forests are expanding again. Mangroves are one of the most carbon-dense ecosystems on the planet. They store far more carbon per hectare than most terrestrial forests and protect coastlines from storm surges. This study suggests that conservation efforts combined with natural regeneration can produce measurable results over decades. For anyone tracking nature-based carbon removal or coastal resilience, this is a concrete data point. It shows that restoration is possible at scale, though the study also notes that regrowth is uneven and some regions still face net loss. The full paper is worth reading for the regional breakdown.
