Mangrove Restoration

Action For Ocean has helped restore 287,240 mangroves across Tanzania’s coastline — planted, protected, and monitored by the communities who depend on them.

Mangroves are a carbon bank and a nursery for marine life in one — they shelter juvenile fish, stabilise shorelines against erosion, and store far more carbon per hectare than most tropical forests. Nearly half of Tanzania’s mangroves have been degraded or lost to clearing and coastal development.

Our Approach

Through community-led nurseries — many of them women-led — AFO replants and protects mangrove forest across all four seascapes. Initiatives like the Mangrove Blue Carbon Project bring together local communities, students, and researchers to restore degraded stands and monitor their recovery, contributing to the 367,500 hectares of coastal habitat AFO has helped protect to date.

Mangrove restoration feeds directly into AFO’s 2030 target of 20 square kilometres of marine habitat restored across Tanzania’s four seascapes — Tanga, Kilwa, Mtwara, and Dar es Salaam.

Every mangrove planted is a carbon bank for the planet and a source of resilience for the community that planted it.

Frequently Asked Questions

How many mangroves has Action For Ocean restored?

AFO has helped restore 287,240 mangroves across Tanzania’s coastline as part of its community-led restoration work.

How does AFO restore mangroves in Tanzania?

AFO works with coastal communities, including women-led mangrove nurseries, to replant and protect mangrove forest across Tanzania’s four seascapes — Tanga, Kilwa, Mtwara, and Dar es Salaam.

Why do mangroves matter for marine conservation?

Mangroves act as nurseries for the fish stocks that sustain coastal fisheries, protect shorelines from erosion and storms, and store significant amounts of blue carbon.

What is AFO’s mangrove restoration approach?

AFO trains local communities, particularly women-led groups, to run mangrove nurseries and lead replanting efforts, treating restoration as a livelihood activity rather than an external intervention.
