sustainable agriculture and climate-smart farming with Enhanced rock weathering.
SINC.EARTH is piloting Enhanced Rock Weathering in West Africa. Sequestering carbon from the atmosphere, whilst improving livelihoods of smallholder farmers.
What is eRw?
Accelerated natural weathering process by use of silicate rocks
Basalt reacts with CO₂ + rainwater and permanently stores carbon
Releases nutrients that improve soil fertility and crop performance
One solution that addresses climate change,
soil degradation, and farm resilience simultaneously
The ghanaian context
Soils are increasingly depleted due to intensive cropping. Decreasing fertility limits yields and food insecurity
Heavy reliance on chemical fertilisers, increasing costs for smallholders
Farmers are actively seeking low-cost, regenerative solutions that improve yields and long-term soil health.
Why Ghana?
Land Availability
15 million hectares cultivated
Strong agricultural education network
60% of population is farmer
Tropical Climate
Tropical climate speeds up
processHigh rainfall is an essential driver
of CO₂ captureActive soils & strong biological activity
Silicate Availability
Local availability of basalt
Large, industrial mining sector
Low transport emissions
Good infrastructure
Our approach
1. Basalt sourcing
2. Application on land
3. weathering & MRV
4. Carbon credits
The pilot
LocationS:
Demonstration plots at three agricultural colleges: Kwadaso, Ejura and Wenchi
Colleges have expert instructors and engaged students in agronomy and sustainable farming
Located close to local basalt sources, ensuring easy logistics and relevance
Methodology
Three sites per college with 0 / ½ / full dose
Application of locally sourced basalt
Testing ERW in Ghana-specific farming
conditionsMonitoring includes carbon uptake, soil fertility, and crop performance
Impact
Validate ERW effectiveness in Ghana’s climate and soils
Generate high-quality MRV data for scaling across West Africa
Build capacity among students, instructors, and surrounding farmer communities
