New analysis reveals 'encouraging' global mangrove cover increase despite losses in key regions
Global mangrove cover—vegetation vital to tackling climate change—has increased over the past 40 years, despite significant losses in some key regions, according to a new analysis.
A new analysis led by Aberystwyth University reveals a global increase in mangrove cover over the past four decades, despite significant losses in certain regions. Mangroves, vital ecosystems that protect coastlines and sequester carbon, have experienced a net gain of 47,720 hectares, according to the Global Mangrove Watch's latest update.
However, the overall rise in mangrove cover does not hide major declines in key areas. Indonesia, home to the world's largest mangrove area, has lost 2,044 square kilometers since 1985, while Myanmar, Malaysia, and Nigeria have also reported substantial losses. Dr. Pete Bunting, a contributor to the research, emphasizes that while the overall increase is encouraging, the progress is uneven.
He notes that some regions continue to suffer from significant mangrove declines, caused by both restoration efforts and natural processes. The improved mapping capabilities of the Global Mangrove Watch, powered by advanced satellite imagery and machine learning, provide detailed insights into mangrove gains, losses, and stability.
This information aids researchers, conservationists, and policymakers in understanding the complexities of mangrove change and supporting effective conservation efforts.
