About Yagasu

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

We are moving through successive reforestation work from the North Island to the Interior Groves, planting a variety of mangrove species cultivated in the local nursery and imported from across East Java. In tandem with the mangrove planting work, we’re supporting a women’s artisanal mangrove project for local aquaculture and a silviofishery program with the local cast net fisherman.

Why it matters locally

Yagasu is working together with the local community in Aceh, North Sumatra, and Riau province to increase resilience of the most vulnerable communities and reduce emissions from land-use change. This is a rich forest area with twisting tidal rivers, numerous wading birds, forest animals, and amphibians.

While diverse with plant life, mangroves are at the heart of this forest, performing critical functions to keep the forest alive. Sadly, rampant deforestation has put this area under threat from frequent flooding due to stormwater, coastal erosion, and loss of habitat for numerous non-human animal and plant life.

This mangrove deforestation has also led to loss of ecosystem resources that support livelihoods, secure nutritious food supply, and secure freshwater supply (by preventing saltwater intrusion) for members of the local community.

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.

Project Managers

Bambang Suprayogi

Owner & CEO

I am the Owner & Executive Director of Yagasu. I have an academic background in environmental sciences, forest conservation and management, wetland survey and management, animal science, and economic-development study.

Meilinda Suriani Harefa

Programme Director

I have 25 years of experience working for environmental organisations and have received an award from the President of Indonesia as an environmental fighter in 2019 for efforts to carry out mangrove restoration. I built YAKOPI to expand the ecological restoration area and improve the economy of coastal communities in an environmentally sustainable way.

Benefits

Equitable

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

Data-driven

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

Supporting the locals

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

The Sustainable Development Goals

End poverty in all its forms everywhere

Achieve gender equality and empower all women and girls

Ensure sustainable consumption and production patterns

Take urgent action to combat climate change and its impacts

Conserve and sustainably use the oceans and marine resources

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.

Every X months, a quantified verification report of the impact will be made publicly accessible, making all impact claims evidence-based and scientifically valid.
