Global Mangrove Forests Rebound, Offering Hopeful Sign for Climate and Coastal Resilience
Mangrove forests, once considered one of the world’s most threatened coastal ecosystems, are showing signs of recovery worldwide, according to new research from Tulane University that finds decades of losses largely offset by regrowth and expansion.
The study, based on four decades of satellite data and published in the journal Science, finds that mangrove forests worldwide are no longer in net decline and are now growing overall. After decades of loss driven by deforestation and coastal development, mangroves are expanding in many regions, largely through natural regeneration and expansion into newly formed coastal areas.
The findings suggest a more hopeful trajectory for these ecosystems, which play a critical role in protecting coastlines, supporting fisheries and storing climate-warming carbon.
“After decades of loss, we’re finally seeing a global turning point for mangroves,” said Zhen Zhang, a postdoctoral scholar at Tulane University School of Science and Engineering and lead author of the study. “This highlights their strong resilience and their potential as a powerful nature-based solution for climate mitigation and coastal protection.”
