Soil carbon storage in mangrove forests.

Soil Carbon Storage in Mangrove Forests
Neftaly Environmental Conservation Spotlight

Mangrove forests are among the most powerful carbon sinks on Earth, playing a pivotal role in climate regulation and coastal protection. These unique coastal ecosystems store vast amounts of carbon, particularly in their soils, making them essential allies in the fight against climate change.

Why Mangroves Matter for Carbon Storage

Mangroves accumulate carbon through their dense root systems and thick layers of organic-rich soil. Unlike terrestrial forests, up to 90% of the carbon stored in mangrove ecosystems is found belowground, locked away in soils for centuries—sometimes millennia—if undisturbed.

Key Features of Mangrove Soil Carbon

• High Sequestration Rate: Mangrove soils can sequester carbon up to four times faster than tropical upland forests.
• Long-Term Storage: Waterlogged, anaerobic soils slow decomposition, allowing carbon to remain stable over long periods.
• Protection from Erosion: Root structures trap sediment and organic material, further enriching carbon content.

Threats to Mangrove Soil Carbon

Despite their importance, mangroves face serious threats:

• Coastal development and land conversion for agriculture or aquaculture often involve clearing mangroves and disturbing carbon-rich soils.
• Pollution and rising sea levels can degrade mangrove health, reducing carbon uptake and storage.

When mangroves are destroyed, decades of stored carbon are released, contributing significantly to atmospheric greenhouse gas levels.

Protecting Mangrove Carbon Stores

To maximize the climate benefits of mangroves, we must:

• Preserve intact mangrove forests through strict conservation policies.
• Restore degraded mangrove areas using native species and community-led initiatives.
• Incorporate mangrove soil carbon into blue carbon strategies and national climate plans.
• Support local and indigenous stewardship, recognizing their role in protecting these ecosystems.
