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
    process

  • High rainfall is an essential driver
    of CO₂ capture

  • Active 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

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
    conditions

  • Monitoring 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
