Plant mangrove trees with Yagasu

Yayasan Gajah Sumatra (Yagasu) is a non-profit organisation planting mangroves in Aceh, North Sumatra, and Riau - Indonesia.

Pure Health Strategy backs Yagasu’s mangrove restoration projects, capturing CO2 while supporting local communities and threatened ecosystems.

About Yagasu

Yagasu has over two decades of experience in mangrove reforestation in coastal ecosystems.

From the North Island to the Interior Groves, they plant a variety of mangrove species, which were cultivated in the local nursery and imported from East Java. Planting trees not only captures lots of carbon, it also creates habitats where wildlife can thrive.

Yagasu also helps the local communities by encouraging sustainable fishing and crab farming. This means they can earn a living without relying on jobs such as cutting down trees. Yagasu also supports a women’s artisanal mangrove project, as well as a silvofishery program.

Why it matters locally

Climate change is a threat to us all. And mangroves are one of our strongest allies in minimizing its impact on the planet. Working directly with the Aceh, North Sumatra, and Riau provinces, planting mangroves makes a difference by:

  • Shielding areas that are prone to extreme weather, such as cyclones and tsunamis
  • Protecting native wildlife which are threatened by deforestation
  • Absorbing and storing more carbon than other trees
  • Supporting livelihoods and the local economy while making local communities more resilient
  • Balancing land and aquatic ecosystems, so plants, animals, and nutrients can move between land and sea

Why this project matters globally

Mangrove forests have a strategic function – connecting and balancing terrestrial and marine ecosystems – where plants, animals and various nutrients are transferred to land or sea through mangroves.

They are also our strongest ally in supporting mitigating climate change and further increase in global warming. Dubbed as “blue carbon” systems, mangroves absorb and lock more carbon into the soil than any other comparable natural terrestrial ecosystem.

As a conservative estimate, each tree in this project will sequester over 250 kilograms of carbon over 20 years of forest growth. This is around 5 times more than any terrestrial forest.

Benefits

  • Benefits Image
    Equitable

    Planting and nursery work is supported by expert foresters and a large contingent of local women's groups.

  • Benefits Image
    Data-driven

    Pre and post-project data is collected and will be published for open-access public review.

  • Benefits Image
    Supporting the local community

    Mangrove restoration will ensure long-term livelihoods for local silvofishery businesses, thereby discouraging deforestation.

Verification

Our methodology is backed by strong science. We use proven algorithms for carbon calculations, and track impact where possible with remote sensing and machine learning.

With our science partners,Global Mangrove Trust and Kumi Analytics, we’re working at the cutting edge of how to measure carbon absorption from space, driving change to make sustainability finance accessible to the humblest communities.

Financial Transparency

We use a mobile app to confirm delivery of all funds to the field.

We will soon write these deliveries on a public digital system, to allow sponsors to follow the flow of donations. We are also creating tools to talk directly to the community about developments in the local community. These peer-to-peer links open the black box of how referral dollars translate into real-world impact!
