According to a report from CNN, farmers could potentially practice farming in a way that would remove carbon from the air and put in into the ground.
From soybeans to corn to pine trees, plants already move carbon out of the air. The report suggests that with enough financial motivation and innovation, farmers could continue growing food while also practicing carbon management. Substances like biochar, charcoal and other organic material that is almost pure carbon, can be sprinkled over soil to keep carbon in the ground for thousands of years, and it doesn’t go back into the atmosphere.
The 2018 IPCC Lands Report says that nearly a quarter of greenhouse gas emissions come out of the agriculture sector, pointing to diesel fuel and synthetic fertilizer. Gene Tackle, a co-author of the National Climate Assessment, said in the CNN report that farmers could be key allies in helping to reduce, and even eliminate, global greenhouse gas emissions.
The National Climate Assessment projects that the amount of days that exceed 90 degrees in Des Moines could increase from 17 days to 70 by mid-century. Additionally, the latest IPCC report finds that growing food around the world will only become more difficult as the weather becomes more unpredictable.
Farmers in Iowa were burdened this past year with extremely heavy rainfall and flooding, as well as an ongoing trade dispute between the U.S. and China that has made it hard for some farmers to sell goods. There are currently no mandatory conservation practices that farmers must practice in Iowa – extra conservation practices are done on a voluntary basis across the state.
