Episode notes
Tea Estate Embraces Carbon Removal
- Shreya Garwal, fourth-generation tea planter, shares how her tea estate in India adopted enhanced rock weathering.
- This method revives degraded land, improves tea quality, and supports biodiversity.
India’s Ideal Conditions for Rock Weathering
- India's climate and abundant basalt rocks create ideal conditions for fast rock weathering.
- These factors could enable carbon removal at a billion-tonne scale in India.
Rock Dust Boosts Tea Yields and Soil
- Basalt rock dust improves soil health by releasing nutrients and increasing crop yields.
- At the Selam tea garden, yields improved by 15-20%, boosting revenue alongside carbon removal.
