Virginia farmers work to reduce carbon emissions

Virginia farmers’ carbon sequestration efforts play into a national trend of reducing agricultural emissions, even as cropland productivity increases.

Carbon emission levels have remained consistent for 30 years while agriculture production has grown significantly. This is due to climate-smart farming practices and associated technologies embraced by agricultural producers, according to a new analysis of U.S. Environmental Protection Agency data.

The analysis highlights agricultural emissions reductions, and the importance of developing new research and technologies to capture more carbon in cropland and pastureland. The American Farm Bureau Federation also examined trends in U.S. carbon sequestration as climate-smart farming practices increase.

The EPA report showed U.S. carbon sinks offset 12% of greenhouse gas emissions, and sequestered 764 million metric tons during 2018. A carbon sink is a natural system that lowers carbon concentration in the atmosphere by accumulating and storing carbon dioxide. A variety of practices with carbon capturing or reduction benefits are widely used on agricultural lands in Virginia, including cover crops, no-till and reduced-tillage planting, anaerobic digesters and nutrient management plans.

The report also said cropland productivity has increased by almost 50% since 1990, while the associated carbon emissions and carbon sinks remained consistent. This supports existing evidence that farmers are raising more food and fiber and producing more renewable fuels using fewer resources by utilizing smarter practices.

Ben Rowe, national affairs coordinator for Virginia Farm Bureau Federation, said the state’s farmers are open to new technologies and practices to improve efficiency. What’s good for a farmer’s bottom line is often beneficial to the environment as well, but help is needed to implement those strategies.
