Transforming global
rice production with SRI

ClimateRice is a collaboration between
Cornell University & CarbonFarm

We aim to scale up the System of Rice Intensification (SRI)

to 1/3 of global rice area in 10 years

To get there, we're creating a self-financing model with carbon credits

4 billion people depend on rice every day

The way we grow rice needs to change

  • 15% yield loss expected by 2050 due to climate change

  • 12% of anthropogenic methane emissions come from rice

  • 33% of global fresh water is used to irrigate rice

  • 80% of rice is grown by smallholder farmers

A climate-resilient alternative exist 

The System of Rice Intensification (SRI)

A simple method based on agronomy, agro-ecology and farmer knowledge


Early plant establishment

Transplant young seedlings to maximize time for shoot and root development


Low plant density

Allow for unconstrained root and shoot growth by reducing plant population by 90%


Regenerating soils

Regenerate soils with organic matter, benefiting soil biology that supports plant growth


Intermittent Irrigation

Aerate the soil and allow roots and beneficial soil organisms to thrive

For the farmers

  • +20 to +100% increase in smallholder profits

  • improved soil quality 

For the environment

  • 50% reduction in methane emissions

  • 30% reduction in water use

For food security

  • Increased grain yield of 20-50% and more, independent of varieties

  • Improved resilience to drought, flooding and extreme wind events

Scaling SRI globally requires money to train and support farmers...


... so we're creating a virtuous self-financing model.

This is our self-financing model

1. Train farmers

2. Measure  impact

3. Sell carbon credits

1/ Train farmers

Provide training and support to farmers to adopt SRI

2/ Measure the impact

Use satellites to measure, report and verify the reduction in methane emissions

3/ Sell carbon credits

Issue and sell registry-certified carbon credits to companies striving to reach Net Zero emissions

4/ Repeat

Use carbon credit sales to reward farmers, and train and support new ones

Our Impact

We're targeting 55M hectares over the next 10 years.

That's one-third of global rice farmland.

+40% increase in smallholder profits

Higher yields.

Lower input costs.

Extra revenue from carbon credits.
