Enhanced Rock Weathering Boosts Carbon Removal for India’s Farmers

Enhanced rock weathering is rapidly emerging as one of the most promising carbon removal solutions for farmers across India. By accelerating the natural process of weathering using finely crushed basalt, we can remove atmospheric carbon dioxide, restore soil health, and provide substantial economic benefits.

“Enhanced rock weathering can remove up to 3.7 billion tons of CO2 globally each year.”

Introduction: Enhanced Rock Weathering and India’s Role in Carbon Removal

As our planet faces increasing climate challenges, the urgency for efficient carbon removal solutions is higher than ever. The XPRIZE Carbon Removal competition recently recognized a significant breakthrough spearheaded from London and being implemented in India, where startups like Mati Carbon are showcasing the practical use of enhanced rock weathering. By applying finely crushed basalt over agricultural lands, this highly durable solution not only fast-tracks atmospheric carbon dioxide removal (CDR) but also delivers remarkable agronomic and economic benefits to smallholder farmers.

With carbon dioxide emissions accounting for more than two-thirds of all anthropogenic greenhouse gas emissions, removing these gases from the Earth’s atmosphere and oceans is paramount. The XPRIZE’s recognition validates the science and promotes building the infrastructure needed for scalable climate resilience across developing economies including Tanzania and Zambia.

Understanding Enhanced Rock Weathering: The Science Driving Carbon Removal Solutions

Enhanced rock weathering employs a natural process that is fundamental to the Earth’s climate system. Here, we spread finely crushed basalt—a silicate-rich volcanic rock—across agricultural lands. When basalt interacts with rainwater and soils, it chemically reacts with CO2 from the atmosphere, forming stable carbon compounds that are washed into the oceans, thus removing atmospheric carbon dioxide permanently.

• Basalt application on farmland accelerates the time needed for natural weathering and boosts global greenhouse gas emissions reduction.
• This durable solution draws down carbon while replenishing soils with minerals invaluable for crop health.

How Enhanced Rock Weathering Works: Accelerating a Natural Process for Permanent Carbon Capture

Let’s break down the process:

1. Basalt Crushing: Basalt rocks, abundant and rich in minerals, are mined and finely crushed to increase surface area and reactivity.
2. Spreading Over Farmlands: This crushed basalt is then spread across agricultural lands at the beginning of the cropping season.
3. Chemical Reaction: In the presence of rainfall and humid conditions, basalt reacts with CO2 in the atmosphere, forming stable carbonates and other minerals.
4. Permanently Draws Down CO2: The result is permanent carbon capture as these compounds are leached into water bodies and sequestered for thousands of years.

This cycle not only achieves effective greenhouse gas removal but also rejuvenates soils by restoring nutrients like calcium, magnesium, and potassium that contribute to healthy crop growth.

“Indian smallholder farmers could increase income by 15% through scalable enhanced rock weathering practices.”

India’s Potential for Carbon Removal Through Weathering: A Global Catalyst

With over 150 million hectares of arable land and more than 100 million smallholder farmers, India offers unparalleled potential for the adoption of enhanced rock weathering as a scalable climate resilience strategy. The sheer scale of agricultural lands means even modest per-hectare rates of carbon removal can translate into immense results nation-wide and inspire climate action across developing economies worldwide.

Mati Carbon’s model, celebrated in London and lauded in the global competition, demonstrates that by engaging thousands of farmers in India, Tanzania, and Zambia, we can employ a locally-led, scientifically robust, and economically inclusive approach. This strategy directly empowers those who are least responsible for climate change but most vulnerable to its consequences.

Climate Resilience, Greenhouse Gas Emissions Reduction & the Power of Weathering

Enhanced rock weathering offers a rare win-win in climate action in agriculture. It substantially reduces greenhouse gas emissions and also improves soil structure and fertility. These outcomes are vital in the context of India’s smallholder-dominated agricultural model, where climatic shocks hit degraded lands and financially strained farmers the hardest.

• Extreme weather events—from droughts to floods—have a disproportionate impact on smallholders with limited infrastructure and financial resources.
• Fixing climate resilience through permanent carbon capture addresses both immediate agronomic risks and long-term sustainability in developing economies.

Benefits for Smallholder Farmers: Improving Income & Restoring Soil Health Naturally

At the heart of this solution lies our commitment to improving smallholder farmer income and restoring soil health naturally. Free basalt application on farmland not only removes atmospheric CO₂ but also increases yields by an average of 20%. This translates to empowered farming communities who can pay off debts, invest in better farm inputs, and build resilience against climate uncertainties.

• Income Boost: The enhanced output from rejuvenated soils means more crops can be sold, further buffers are available for financial hardship, and debts can be paid faster.
• Soil Rejuvenation: Basalt restores minerals lacking in degraded lands, leading to long-term soil health gains.
• Zero Cost to Farmers: The program is expressly built to require zero financial outlay from smallholder farmers, making it universally accessible.
• Climate Resilience: Improved nutrition, yield reliability, and carbon removal deliver an integrated response to climate threats.

For those with limited access to fertilizers or credit, enhanced rock weathering interventions are a lifeline—delivering both agronomic empowerment and planetary healing.
