Harnessing the power of nature-based solutions

Coastal lands and waters across the Pacific are under intense pressures. Project Halo is working alongside local communities to build a new future through nature-based solutions.

Why Project Halo?

Mangroves are a type of halophyte — a salt-loving plant that grows in or near tidal waters. As tropical and subtropical ecosystems, mangrove forests create a green ring (a halo!) that encircles the earth, delivering benefits for people and the planet.

Our research

The challenge

Globally, coastal communities are impacted by biodiversity loss and climate change. These joint challenges are profoundly impacting the Oceania region. How can national and international goals to address societal, environmental, and carbon reduction needs be achieved hand-in-hand with community empowerment?

The solution

We believe that nature-based solutions, such as mangroves, have the capacity to provide coastal protection services while also increasing biodiversity and supporting communities. To achieve this we are implementing large-scale mangrove restoration projects while also integrating mangroves into maritime infrastructure.

The benefits

By combining biophysical, social, and policy research with on-ground engineering, Project Halo will showcase the world's best approaches for nature-based solutions. Our evidence-based approach ensures that the outcomes of Project Halo are transparent, scaleable, and encourage collaboration.
