The Role of Blue Carbon in Combating Climate Change

 

As the world grapples with the impacts of climate change, scientists are increasingly turning their attention to the potential of blue carbon ecosystems to mitigate carbon emissions. Blue carbon refers to carbon stored in coastal and marine ecosystems, including mangrove forests, seagrass meadows, and salt marshes.

According to a study published in Nature, these ecosystems are estimated to store over 30 billion tonnes of carbon globally. Restoring and conserving these ecosystems could significantly contribute to offsetting the world's carbon emissions, potentially canceling out around three percent of annual emissions.

Unlike terrestrial ecosystems, where carbon is stored in vegetation, blue carbon ecosystems store carbon in their sediments. This makes them highly effective carbon sinks, removing carbon dioxide from the atmosphere and storing it for long periods.

Maitha Al Hameli from the Environment Agency - Abu Dhabi (EAD) emphasizes the importance of these ecosystems in carbon sequestration. She explains that as long as these ecosystems remain undisturbed, they can continue to store carbon for many years, making them valuable tools in the fight against climate change.

In addition to their role in carbon sequestration, blue carbon ecosystems provide a range of ecosystem services, including coastal protection, habitat for biodiversity, and water filtration. Protecting and restoring these ecosystems not only helps mitigate climate change but also provides valuable benefits for both nature and society.
