World's mangrove forests see net gain after decades of losses

Global mangrove forests have shifted from net loss to net gain since around 2010, a study published in Science found after analysing four decades of satellite data. The world lost nearly 2,900 sq km of mangroves between the 1980s and 2010, but recorded a net gain of 2,033 sq km from 2010 to 2023, leaving an overall decline of 0.5%.
