Are Blue Carbon Habitats the New Trend?

As climate change continues to affect environments worldwide, many regions are investing in resource development projects to create blue carbon habitats that sequester atmospheric carbon and reduce urban footprints in nature. Restored blue carbon habitats are quickly appearing along coastlines worldwide, and many scientists have mixed reviews over their contributions to carbon sequestration on a global scale. 

Blue carbon habitats along coastlines are a natural phenomenon observable in mangroves, saltmarshes, and seagrass meadows. These vital coastal habitats sequester large amounts of carbon from the atmosphere and serve as an essential barrier to storm surges and water inundation. Many coastal areas have been degraded due to modernization. Mangrove forests are bulldozed to make way for new beach high rises, and seagrass meadows are quickly eradicated. 

These invaluable coastal habitats support an array of life, with some of the highest biodiversity found anywhere in the world. Areas like mangroves often involve a community of intertwined plants and foliage that create an almost impenetrable wall, preventing the onset of incoming storm surges and rising water levels from reaching areas of land on their adjacent side. After removing large sections of mangrove forests, areas in Florida along the southeastern United States faced millions of dollars in damages after previously mundane tropical storms escalated into national disasters without any natural barriers. What was once a moderate storm surge quickly turned into urban flooding, beach erosion, and unprecedented damages. 

As environmentalists and lawmakers quickly realized the monetary and public safety significance of such vital resources, they began investigating ways to restore and instill new habitat areas that can contribute the same kind of preventative measures these areas once had. The additional benefit of these coastal regions’ ability for carbon sequestration increased their market value on a global scale, as it was thought that large-scale climate change could even be combated. 

Conservation of these regions provides natural climate solutions by conserving greenhouse gas emissions stored inside of their systems and by increasing the carbon dioxide drawn down as areas are restored or created. Experts argue the individual use of these systems to reduce carbon emissions in the atmosphere is negligible on a global scale and should only be practically used as a mitigation measure while focusing on preserving their valuable biodiversity potential. 

The presumed carbon footprint benefits of restoring coastal ecosystems must have contributions from elsewhere. Otherwise, atmospheric carbon will continue to provoke future climate change. These blue carbon habitats and the associated movement will still have lasting impacts on coastal biodiversity and infrastructure defense, even if their carbon impacts are not as significant as previously thought.

Coastal regions should continue to develop and explore the benefits of restoring their coastal ecosystems to restore natural balance to their native flora and fauna while also contributing to mitigating carbon emissions in the atmosphere.
