Blue Carbon Ecosystems
Blue carbon ecosystems refer to coastal and marine habitats such as mangroves, salt marshes, and seagrass meadows that capture and store large amounts of carbon dioxide from the atmosphere. These ecosystems play a crucial role in mitigating climate change by sequestering carbon in both their plants and soils. Protecting and restoring blue carbon ecosystems helps reduce greenhouse gas emissions, supports biodiversity, and provides important benefits for coastal communities.

❓ Frequently Asked Questions
What are blue carbon ecosystems?
Coastal and marine habitats that store carbon in plants and soils, especially in sediments. Key examples include mangroves, salt marshes, and seagrass meadows.
Which habitats are typically classified as blue carbon ecosystems?
Mangroves, salt marshes, and seagrass meadows.
How do blue carbon ecosystems help combat climate change?
They remove CO2 from the atmosphere and store it in vegetation and, especially, in sediments for long periods.
Why is protecting blue carbon ecosystems important?
They help store carbon, protect coastlines from erosion and storms, and support biodiversity and water quality.
What threats do blue carbon ecosystems face?
Coastal development, land conversion and drainage, pollution, and climate change; restoration and conservation can help recover their carbon stores.
