International Day for the Conservation of the Mangrove Ecosystem

26 July

Mangroves are rare, spectacular and prolific ecosystems on the boundary between land and sea. These extra ordinary ecosystems contribute to the wellbeing, food security, and protection of coastal communities worldwide. They support a rich biodiversity and provide a valuable nursery habitat for fish and crustaceans. Mangroves also act as a form of natural coastal defense against storm surges, tsunamis, rising sea levels and erosion. Their soils are highly effective carbon sinks, sequestering vast amounts of carbon.

Yet mangroves are disappearing three to five times faster than overall global forest losses, with serious ecological and socio-economic impacts. Current estimates indicate that mangrove coverage has been divided by two in the past 40 years.

"Mangroves are in danger: it has been estimated that more than three-quarters of the world��s mangroves are under threat along with all the aquatic and terrestrial organisms that depend on them. For this reason, UNESCO is acting to protect them and other valuable blue carbon ecosystems, through its networks of Biosphere Reserves, Global Geoparks and natural World Heritage sites."

Did you know ?

Mangroves are extraordinary ecosystems

located at the interface of land and sea in tropical regions, which offer a considerable array of ecosystem goods and services.

Mangrove forests are globally rare

Although they are found in 123 nations and territories, they represent less than 1% of all tropical forests worldwide, and less than 0.4% of the total global forest estate

Mangroves contribute to the wellbeing, food security, and protection of coastal communities worldwide.

These forested wetlands are rich in biodiversity

They support complex communities, where thousands of other species interact. They provide a valuable nursery habitat for fish and crustaceans; a food source for monkeys, deer, birds, even kangaroos; and a source of nectar for honeybees.

Mangroves help ensure food security for many coastal communities

Managing and restoring mangrove ecosystems is an achievable and cost effective way to help ensure food security for many coastal communities.

UNESCO��s Biosphere Reserves offer a unique blueprint to protect mangrove ecosystems

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.

Mangroves play a role in climate mitigation.

Mangrove ecosystems are highly effective carbon sinks

sequestering vast amounts of carbon within the soil, leaves, branches, roots, etc.

One hectare of mangrove can store 3,754 tons of carbon

it��s the equivalent of taking 2,650+ cars off the road for one year.

If destroyed, degraded or lost, mangroves become sources of carbon dioxide

Experts estimate that carbon emissions from mangrove deforestation account for up to 10% of emissions from deforestation globally, despite covering just 0.7% of land coverage.

UNESCO marine World Heritage sites host 9% of global mangrove carbon assets

Mangroves act as a natural coastal defense against storm surges, tsunamis, rising sea levels and erosion.

Mangroves play an important role in reducing vulnerability to natural hazards

and increasing resilience to climate change impacts.

"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."

Audrey AzoulayUNESCO Director-General

UNESCO is engaged deeply in supporting the conservation of mangroves, while advancing the sustainable development of their local communities. The inclusion of mangroves in Biosphere Reserves, and UNESCO Global Geoparks contributes to improving the knowledge, management and conservation of mangrove ecosystems throughout the world.

UNESCO is engaged at the scientific and policy levels to protect, manage or restore global (mangroves, seagrasses and tidal/salt marshes) for addressing climate change. Healthy blue carbon ecosystems also provide habitat for marine species, support fish stocks and food security, sustain coastal communities and livelihoods, filter water flowing into our oceans and reef systems, and protect coastlines from erosion and storm surges.
