Across East and Central Africa, smallholder farmers face harsh realities: poor soil, unpredictable weather, and relentless crop loss. Fires rage to clear land, filling the air with deadly smoke, while expensive fertilizers remain out of reach. 

​But one woman is sparking a quiet revolution—armed with nothing but knowledge, a shovel, and a commitment to share.

Biochar is a proven, ancient solution made by burning biomass in a low-oxygen pit or drum. Even the poorest farmers can do it—with a shovel and a bit of knowledge.
Sr. Paulette teaches:

• Drum biochar systems for those with access to barrels
• Trench and pit biochar for those with only soil and a shovel

 No chemicals. No big investments. Just results.

What began as a small experiment has grown into a movement:

• Farmers across Malawi, Burundi, Uganda, Kenya, Zimbabwe, DR Congo, and Tanzania are now making and using biochar.
• They’re growing corn, millet, vegetables—and raising pigs, chickens, cows, even quail—with healthier soil and stronger animals.
• And yes, they’re teaching their neighbors.

The results? Bigger harvests. Cleaner air. Healthier communities.
