Blue Ventures | Protecting Mangroves With Coastal Communities

Since 2019, One Earth has supported Blue Ventures' work developing integrated mangrove forestry and fisheries conservation projects at three sites in Madagascar (Ambanja, Mahajamba, and Velondriake) and two sites in Indonesia (Sembilang National Park and Kuba Raya). 

Mangrove forests sustain the daily lives of hundreds of millions of coastal people across the tropics, providing them with critical services from timber and fuel to shrimp, crab and fish. They underpin wider offshore fisheries, stop coastal erosion and improve water quality. Without them, coral reefs, seagrass meadows and the broader marine ecosystem cannot thrive.

And that’s not all. Mangroves act as natural storm barriers, saving lives and protecting infrastructure against extreme weather and rising seas. They also capture and store staggering amounts of atmospheric carbon. By protecting and restoring mangroves, we can keep this “blue carbon” locked away and help achieve the large-scale carbon drawdown needed to limit global warming to 1.5°C.

Yet despite their enormous value, at least one quarter of the world’s original mangrove cover has already been deforested, and the rate of this decline is forecast to increase.

The drivers of this mangrove loss are complex and interconnected. Many people who depend on mangroves live in conditions of extreme poverty with few viable alternatives to mangrove fishing and charcoal or timber production. People often have no choice but to use mangroves unsustainably, and many communities don’t have the access rights to stop clearance of their local mangroves by outside developers, such a commercial aquaculture or coastal development projects.

Continued loss of mangroves and their many benefits will have devastating economic, social and environmental impacts, worsening food insecurity, impoverishing communities and biodiversity, and heightening the vulnerability of communities already living on the front lines of climate breakdown. A solution is urgently needed that provides a viable pathway to protecting mangroves at scale.

Over the last 15 years, Blue Ventures has been innovating ways for coastal communities to both safeguard mangroves and earn a better living from them. Our Blue Forests approach secures mangrove rights, builds strong governance, improves mangrove fisheries and forestry management, and establishes initiatives for alternative livelihoods. This lays the foundation for projects that can monetise the value of blue carbon in order to finance community-led conservation and restoration of mangroves.
