Working together to harness the power of nature-based solutions in the Pacific

Coastal lands and waters across the Pacific are under intense pressures. Project Halo is working alongside local communities, using science and innovation to revitalise mangrove ecosystems.

The power of mangroves

Mangrove forests are among the most vital ecosystems on Earth. They shield coastlines from storm surges, sequester carbon far more efficiently than terrestrial forests and maintain thriving ecosystems that are vital for food security.

For communities in the Pacific, mangroves are more than just a part of the natural environment, they are a lifeline. Mangroves protect homes, support livelihoods and offer cultural connection.

By nurturing these powerful coastal forests, Project Halo is serving as a model for climate adaptation and community empowerment that can be replicated across island nations worldwide.

Our research

Restoring the tide

Our tidal research and novel solutions are reversing the high failure rates of mangrove planting efforts and securing long term mangrove success. By better understanding and reinstating natural hydrological processes, we’re supporting the natural regeneration of mangrove forests in degraded coastal lands.

Floating forests

Our world-first Mangrove Integrated Coastal Infrastructure pontoons are being refined, deployed and monitored in urbanised coastal sites. Integrated into existing and new marine infrastructure, they’re improving water quality, absorbing wave energy. reducing deforestation pressures and providing valuable green habitat.
