TAHIRY HONKO overview
Through mangrove conservation, the project supports fisheries management and other initiatives that grow the local economies. These then bring health care, education and wells for the local communities.
Mangroves themselves provide a habitat for sea life and help protect coastal areas from flooding. They sustain local communities with food, fuel for cooking, timber for building and generate local income. The mangroves need managing sustainably, so the project is developing initiatives for alternative livelihoods, including sea cucumber and seaweed farming and mangrove beekeeping.

What people say
“Mangroves and other ‘blue carbon’ ecosystems like sea grasses and salt marshes are incredibly efficient at storing carbon. They can absorb and store as much as 10 times more carbon than terrestrial ecosystems—so it goes without saying that they are a critical part of efforts to overcome climate change.”
