In the plant world, mangroves are unique. Inhabiting a hostile environment, they have adapted to survive. Their roots stand in waterlogged ground, almost devoid of all oxygen. Their leaves and trunks are engineered to regulate salinity. To reproduce, they drop not seeds but seedlings – the plant equivalent of a live birth.文章源自英文巴士-https://www.en84.com/11862.html




However, mangroves are much more than marvels of nature. Standing in the intertidal zone between land and sea, mangroves perform a range of services for coastal communities in tropical and sub-tropical regions. They protect biodiversity by sheltering and nurturing marine life. They function like filtration systems, absorbing nutrients and pollutants. They fight coastal erosion, acting as breakwaters to dissipate storm surges and wave energy. Above all, they play an essential role as carbon sinks, sequestering atmospheric and oceanic carbon for long periods of time.




The health of humans has always depended on the health of the planet, but in today’s changing world, the importance of mangrove ecosystems is all too clear. Yet it is estimated that some countries lost more than 40% of their mangroves between 1980 and 2005, often due to coastal development. These plants currently cover a surface of just 14.8 million hectares – an area equivalent to the size of Greece.




The world is now waking up to the importance of mangroves – and other blue carbon ecosystems, including salt marshes, seagrass beds and coastal wetlands. UNESCO has long worked to conserve these essential areas in its World Heritage sites, Global Geoparks and Biosphere Reserves. The ecosystems in its marine World Heritage sites alone span 207 million hectares – 10% of all marine protected areas globally.




When it comes to protecting ecosystems like these, UNESCO’s Biosphere Reserves offer a unique blueprint. In these areas, UNESCO is committed to implementing science-based solutions in coordination with local and indigenous communities, to support humanity’s ability to cope with socio-ecological change. In this way, we are protecting mangrove forests across the globe – from the Ranong Biosphere Reserve in Thailand, to the Delta du Saloum Biosphere Reserve in Senegal, via the Marawah Biosphere Reserve in the United Arab Emirates.




This year, the UNESCO World Network of Biosphere Reserves is celebrating its fiftieth anniversary – five decades of dialogue, knowledge sharing and poverty reduction, to rethink the relationship between people and nature. This year, we also celebrate the launch of the United Nations Decade of Ecosystem Restoration. Through these initiatives and others, we are working to protect mangroves and to better support scientific research into these environments.




However, we cannot do this alone. We also need you – to participate in scientific research, monitoring, education and awareness; to contribute to conservation efforts. Please join us, so that, together, we can put a stop to mangrove habitat destruction, and restore what we have already lost.
