Reforesting degraded landscapes to improve human health.

[Who we are]

What we do.

Fractile Institute, Inc. is a 501(c)(3) nonprofit organization driving the reforestation of degraded landscapes to improve health and economic outcomes in Madagascar and Uganda.

The work on the ground is carried out by Fractile Institute Madagascar and Fractile Institute Uganda, each a registered NGO in its own country. Together, we plant coffee and native trees on degraded hillsides, build rainwater tanks and boreholes, pay field workers roughly twice the local going rate, and test whether restoring forest cover reduces malaria and waterborne disease.

Tojosoa Raherinirainy
Rooted in rural Ihosy, Tojo is dedicated to rural development and planetary well-being. His commitment began at 15, when he co-founded the environmental group Club Masoandro for local tree-planting. A passionate illustrator and photographer, he trained in graphic design in Germany, working for firms like Rova Caviar Company and illustrating seven children's books. His communication skills and international relations expertise were honed over seven years as a Language and Cross-Cultural Facilitator for U.S. Peace Corps Madagascar. He now leverages this experience through his own company, MADEinDAGO, and proudly serves as our Executive Director in Madagascar, merging visual artistry with impactful grassroots service.

Paul Kato
Growing up, Paul witnessed the harsh reality of poverty and extreme suffering. He saw children dropping out of school because their parents and caretakers couldn't afford fees, farmers losing harvests because they lacked access to credit, storage facilities, fluctuating prices, and families forced into endless cycles of debt. These experiences planted a question in him: What if finance wasn't just about profit, but about dignity, opportunity, and hope? Paul believes access to small loans, savings, storage facilities, steady and good market prices for agri-produce and financial education can help transform lives.

Hannah has deep experience and a strong passion for decarbonization solutions that provide community co-benefits. After studying Applied Mathematics and Environmental Engineering at UCLA, she spent several years advising major corporations on reducing emissions across their supply chains. She currently works at a climate-focused asset manager that invests in carbon markets, aiming to drive down global emissions by pricing pollution and holding emitters accountable. Hannah's passion for nature, and her commitment to implementing nature-based solutions that deliver community benefits, stems from a childhood spent deeply connected to the mountains and beaches of Northern California, linking directly to Fractile Institute's mission to improve human health and livelihoods through reforestation.

[what we have built]

On the ground in two countries.

In Madagascar, 2.5 acres of land has been reforested and sixty 5,000 liter rainwater harvesting tanks have been constructed across three villages.

In Uganda, 1.3 acres of degrades land is under restoration and a deep-water borehole serving 4 villages has been drilled.

[how we work]

Run by the people who live there.

The Malagasy and Ugandan teams are salaried and work year round. Every program is delivered by people who live in the communities it serves, not by visitors who leave when the season ends.

“Fractile Institute isn't just an employer. It's a space where I'm allowed to be fully myself. I found a place where two of my deepest aspirations finally have room to breathe: putting my skills and knowledge in service of rural development and planetary health, and growing as a person first.”

Comments from Our Collaborators

Duke PlanetLabDuke University

“The Fractile Institute promises to take the lessons learned in the realm of academic research on Planetary Health out of the Ivory Tower and into the real world, where real people are facing real problems. While the Duke University PlanetLab is a team of researchers working diligently to understand very complex problems associated with global environmental change, we are not in the business of implementing solutions. For that, we need partners like Fractile that are experienced in the regions where they work and have strong connections with local leaders who understand the environmental and social nuances. This is one pathway of many required that will help us to make headway on reducing suffering due to global change.”

“We’re proud to support the Fractile Institute’s mission to restore degraded landscapes, expand access to clean water, and improve health and livelihoods in under-resourced rural communities in Madagascar and Uganda. By bringing Acorn’s molecular testing technology into the field, we hope to give Fractile better tools to understand water quality and measure their work's real-world impact. Meanwhile, their projects give us the opportunity to deploy our technology where it can make a meaningful difference in people’s lives.”
