​Climate change is already hitting the world’s most vulnerable communities hardest—especially the smallholder farmers who produce over 30% of the world’s food. As temperatures rise, rainfall becomes unpredictable, and growing seasons shift, these farmers face shrinking harvests and rising food insecurity.

Floods wash away crops. Droughts leave fields cracked and dry. And pests thrive in the warmer climate, devastating what little survives. In many regions, the soil itself is dying—exhausted by years of overuse and made worse by extreme weather.
​
For families who depend on farming to survive, the impact is immediate and devastating: less food, lower income, and fewer options for the future.
​

At Warm Heart, we’re helping farmers fight back—with biochar.
Biochar is a powerful, low-cost technology made by turning crop waste into a carbon-rich soil amendment. Instead of burning agricultural waste and polluting the air, farmers learn to convert it into biochar, which they return to the soil to rebuild its health.
The results are transformative:

• 🌧️ Resilient Soils: Biochar retains moisture during droughts and protects crops during heavy rain.
• 🌿 Improved Yields: Healthier soil means better harvests—even on depleted land.
• 💨 Cleaner Air: No more crop burning, which means cleaner skies for rural families.
• 🌍 Climate Impact: Biochar captures carbon and stores it in the soil for centuries, helping fight global warming.

This is more than a farming tool—it’s a path to food security, climate resilience, and community empowerment.

🇹🇭 Northern Thailand 
In regions where air pollution from crop burning once choked communities, farmers now turn waste into biochar. Yields have increased, the air is cleaner, and thousands of tons of CO₂ are being captured each year.

🇲🇼 Malawi 
Facing poor soil quality and erratic rainfall, farmers in Malawi are using biochar to rebuild their land. Our training programs are helping communities grow more food with less water while regenerating the soil for long-term productivity.

🇰🇪 Kenya 
In arid regions of Kenya, biochar is restoring the health of overworked soils. Partnering with local groups, Warm Heart is training farmers to use biochar as part of a broader effort to boost food security and climate resilience.

🇨🇩 Democratic Republic of Congo 
Amidst ongoing conflict and displacement, our trainers are helping refugee and host farmers use biochar to restore degraded land. With improved soil fertility, these communities are growing food again—and building hope.

🇹🇿 Tanzania 
​Local women-led cooperatives are using biochar to grow vegetables for both nutrition and income. With better harvests and less dependence on synthetic fertilizers, their farms are healthier and more sustainable.
​

Right now, smallholder farmers are on the front lines of the climate crisis. But with the right tools and training, they’re not just surviving—they’re leading the way toward a more resilient, sustainable future.
Your donation helps us train more farmers, distribute clean technology, and restore soil health where it's needed most. Whether you give once or monthly, you’re putting power directly into the hands of those who need it most.

• $20 trains one farmer in biochar production
