Harley Yodhaloka Launches Mangrove Warrior Initiative
Fourteen year old Indonesian environmental advocate leads a mangrove restoration initiative that has planted more than 30,000 trees while supporting coastal communities.
Indonesia, 20th Mar 2026 – In the coastal wetlands of Surabaya, Indonesia, a young environmental advocate is helping lead a movement focused on ecosystem restoration, climate awareness, and community collaboration.
At only 14 years old, Harley Fatahillah Yodhaloka Sunoto has cultivated and planted more than 30,000 mangrove trees through his environmental initiative known as Mangrove Warrior. The project focuses on restoring degraded coastal ecosystems while promoting a model of environmental leadership driven by youth engagement.
Indonesia has experienced significant environmental pressure in recent years. Over the past decade, an estimated 12.5 million hectares of forest have been lost. This decline has contributed to increased coastal erosion, reduced biodiversity, and heightened vulnerability to climate related disasters.
Observing the growing environmental challenges across the country encouraged Harley to begin exploring ways to contribute to solutions at the community level.
Instead of waiting for large scale institutional responses, he began building an initiative of his own centered on mangrove restoration and environmental education.
Mangrove Warrior Emerges From Community Collaboration
Mangrove Warrior was launched roughly one year ago with the goal of restoring coastal ecosystems while increasing climate awareness among young people.
The initiative began with Harley learning directly from coastal farmers in Wonorejo, a community where livelihoods have long depended on healthy mangrove ecosystems. Together, they developed a mangrove nursery system designed to cultivate seedlings before planting them in vulnerable shoreline areas, while also engaging the school community at SMP Negeri 1 Surabaya to support youth participation and environmental education.
Through this collaboration, Mangrove Warrior has restored several coastal areas including Wonorejo, Gunung Anyar, and Keputih.
The initiative has introduced multiple mangrove species chosen for their ability to adapt to local tidal and sediment conditions. These include Rhizophora mucronata, Rhizophora stylosa, Bruguiera gymnorhiza, Avicennia marina, Bruguiera cylindrica, Sonneratia caseolaris, and Ceriops.
By the end of 2025, Mangrove Warrior had successfully reached its first milestone of cultivating and planting 25,000 mangrove seedlings.
Today the number has grown to more than 30,000 trees, and the project has established a new goal of planting 65,000 mangroves by 2026, with a long term vision of reaching one million mangroves across Indonesia.
Restoring Mangroves in Challenging Coastal Terrain
Mangrove restoration work requires significant physical effort and persistence.
The planting sites are located approximately 13 kilometers from Harley’s home, and reaching them often involves navigating thick coastal mud, sharp mangrove roots, and water levels that can reach chest height.
During planting activities, volunteers frequently encounter difficult terrain while working in dense coastal forest environments. Harley himself has experienced scratches and minor injuries while moving through the mangrove roots and mud.
Despite these obstacles, the restoration effort continues to expand.
For Harley and the Mangrove Warrior team, planting mangroves represents more than tree planting alone. Mangroves provide natural coastal protection by reducing erosion, mitigating tidal flooding, and strengthening resilience against climate change.
These ecosystems also support biodiversity and help stabilize coastal environments that communities depend upon.
Supporting Livelihoods Through Conservation
Mangrove Warrior combines ecological restoration with community empowerment initiatives.
Local coastal farmers participate in cultivating and planting mangrove seedlings alongside the environmental organization Wahana Visi Indonesia. Their involvement helps ensure the long term stewardship of restored ecosystems.
The initiative also supports women in coastal communities by encouraging the development of mangrove based products that provide additional economic opportunities.
This effort is supported through collaboration with Lulut Sri Yuliani, a mangrove conservation advocate from Surabaya and recipient of the Kalpataru Award, Indonesia’s highest environmental honor.
Through this partnership, community members gain knowledge and training on transforming mangrove resources into sustainable products without harming the surrounding ecosystem.
Products developed through the initiative include mangrove syrup, mangrove soy sauce, natural shampoo and conditioner made from mangrove extracts, mangrove charcoal briquettes used as alternative fuel, hair and face vitamins derived from mangrove resources, and batik created using natural mangrove dyes.

This model highlights how conservation initiatives can support both environmental protection and community based economic development.
Environmental Education and Public Outreach
Beyond restoration work, Harley has become increasingly involved in environmental education and youth climate advocacy.
He has presented his work in several national environmental webinars and appeared on a podcast organized by Indonesia’s Ministry of Environment and Forestry. His conservation efforts have also been featured on national television programs discussing youth participation in environmental action.
Media coverage has further expanded awareness of the initiative, with Mangrove Warrior being highlighted in more than 20 articles addressing climate action and youth leadership.
Educational outreach remains a key component of the project. Mangrove Warrior regularly organizes learning sessions designed to introduce students to mangrove ecosystems, coastal resilience strategies, and climate science.
These programs encourage students to understand how coastal ecosystems function and why they are essential for protecting communities and biodiversity.
Innovation Through Waste Reduction Initiatives
Harley’s environmental work also extends beyond mangrove conservation.
He created Eco Geniuz Pillow, a sustainability focused product made using recycled plastic waste. Materials used in the project are collected from several community sources including plastic packaging from local coffee stalls, waste generated by small laundry businesses, and plastic debris collected during beach cleanup activities.
Some of these cleanup initiatives are organized with the environmental community Tunas Hijau Indonesia.
Each Eco Geniuz Pillow includes a barcode that connects users to environmental education materials such as articles and videos about waste management and sustainability practices.
The project demonstrates how everyday household items can also function as tools for environmental education and awareness.
Expanding Environmental Leadership Across Indonesia
Looking ahead, Harley plans to expand the Mangrove Warrior initiative to other regions of Indonesia affected by deforestation and coastal degradation.
Future plans include planting one million mangroves across the country, establishing a Mangrove Warrior store dedicated to sustainable mangrove based products, and developing a Mangrove Conservation School where young people can learn about ecosystem restoration, climate science, and sustainable entrepreneurship.
Harley summarized the initiative’s long term vision in a recent statement.
“As long as I am still able to plant, I will continue planting. I hope Indonesia and the world remain safe for future generations. Through mangrove restoration, we can help restore Indonesia’s role as one of the lungs of the Earth.”
Mangrove Warrior is also open to partnerships and collaborations with organizations that share an interest in protecting coastal ecosystems and supporting community driven environmental initiatives.
