Marine Ecosystem Restoration

Nearly 50% of Tanzania’s coral reefs and mangroves have been degraded or lost threatening food security, coastal protection, and biodiversity.

The ocean can recover, but only if we help it breathe again.
AFO leads large-scale marine restoration that blends science with community power bringing corals, mangroves, and seagrass meadows back to life along the coast of Tanzania.

We work to heal the ocean as a living system: rebuilding habitat, restoring natural balance, and helping communities become guardians of the seas that sustain them. Every reef restored becomes a classroom for resilience, every mangrove planted a carbon bank for the planet and a source of community resilience.

Our restoration work doesn’t stop at ecology it rebuilds dignity, income, and identity.
Because when people are part of the solution, restoration becomes regeneration.

The ocean can’t wait and neither can we.

By 2030, AFO envisions coastlines where restoration is no longer an emergency response, but a way of life.

Our goal is to restore 20 square kilometers of marine habitats, train 150 new divers, and equip 25 local innovators to pioneer homegrown restoration solutions. This future isn’t theoretical; it’s already unfolding through the hands of young Tanzanians welding coral frames, women leading mangrove nurseries, and coastal communities turning degraded reefs into living classrooms.

We call it ecosystem recovery but at its core, it’s human recovery. When people and nature rebuild together, the results ripple far beyond the shoreline.

Frequently Asked Questions

What is marine ecosystem restoration?

Marine ecosystem restoration is the active repair of degraded coastal habitats — coral reefs, mangroves, and seagrass meadows — so they can recover their natural ability to support fish stocks, protect coastlines, and store carbon.

How does Action For Ocean restore coral reefs and mangroves in Tanzania?

AFO trains and certifies local divers and community members to lead hands-on restoration: building coral frames, planting mangrove nurseries, and monitoring seagrass recovery across Tanzania’s four seascapes — Tanga, Kilwa, Mtwara, and Dar es Salaam.

What is AFO’s restoration target by 2030?

AFO aims to restore 20 square kilometres of marine habitat, train 150 new divers, and equip 25 local innovators with homegrown restoration solutions by 2030.

Why does coral and mangrove restoration matter in Tanzania?

Nearly 50% of Tanzania’s coral reefs and mangroves have already been degraded or lost, threatening food security, coastal protection, and biodiversity for millions of people who depend on the ocean.
