Mangroves, often called "blue carbon ecosystems," play an essential role in fighting climate change. These coastal forests not only protect shorelines and support biodiversity but also capture and store significant amounts of carbon.
As climate change accelerates, understanding and preserving these ecosystems is critical for enhancing carbon sequestration, reducing greenhouse gas emissions, and building resilience in coastal communities..
"Mangroves are one of the planet's most effective carbon scrubbers, storing up to five times more carbon per hectare than tropical rainforests. Protecting and restoring these ecosystems can play a significant role in mitigating climate change."
Mangroves are highly effective at capturing and storing carbon dioxide (CO₂) from the atmosphere, a process known as carbon sequestration. Here's how they do it:
-->Photosynthesis: Like other plants, mangroves absorb CO₂ during photosynthesis. They convert this CO₂ into biomass, which forms the trunks, roots, and leaves of mangrove trees.
-->Soil Carbon Storage: Unlike most terrestrial forests, mangroves store significant amounts of carbon in their soils. The dense, waterlogged soil beneath mangrove forests acts like a carbon vault, trapping organic material and preventing it from decomposing and releasing CO₂ back into the atmosphere.
-->Blue Carbon Ecosystems: Mangroves, along with seagrasses and salt marshes, are known as blue carbon ecosystems due to their ability to store carbon in both biomass and soils. This unique ability makes them some of the most efficient carbon sinks in the world..
Despite their importance, mangroves face numerous threats that jeopardize their role in climate change mitigation:
Deforestation: Mangrove forests are cleared for aquaculture, agriculture, and urban development. This deforestation releases the carbon stored in mangrove biomass and soils into the atmosphere, contributing to greenhouse gas emissions.
Pollution: Industrial runoff, plastic waste, and chemicals pollute mangrove ecosystems, disrupting their ability to store carbon and support marine life.
Climate Change: Rising sea levels, increased temperatures, and changing rainfall patterns all impact mangrove health. These stressors can reduce their growth, lower their carbon sequestration capacity, and eventually lead to habitat loss.
