Mitigating Climate Change
February 20, 2013
The switch to conservation tillage uses less fuel and keeps more carbon in the soil – helping farmers mitigate climate change. For example, in Brazil, lower fuel use associated with the adoption of biotechnology from 1996/97 to 2010/11 reduced C02 emissions by 468,400 tons, which equates to preserving 3.5 million trees. Higher crop yields also help mitigate climate change.
The net effect of higher-yielding crops has avoided emissions of up to 590 billion tonnes of carbon since 1961.
By increasing yields on existing fields, farmers are under less pressure to clear carbon-rich forests for more farmland. This avoids billions of tonnes of greenhouse gas emissions that would have occurred through forest clearing. For example, the net effect of higher-yielding crops has avoided emissions of up to 590 billion tonnes of carbon since 1961.
