The earth’s soil stores a lot of carbon from the atmosphere, and managing it with the climate in mind may be an important part of reducing greenhouse gas emissions to curb global warming, according to a paper published Wednesday in the journal Nature.

“Climate-smart” soil management, primarily on land used for agriculture, can be part of an overall greenhouse gas reduction strategy that includes other efforts like carbon sequestration and reducing fossil fuel emissions, the paper’s authors said. Many scientists believe new efforts to reduce greenhouse gases in the atmosphere are needed to keep global warming to an internationally agreed-upon limit of 2°C (3.6°F).

“One way to do that is by locking up carbon in soils,” said study co-author Pete Smith, professor of soils and global change at the University of Aberdeen in Scotland. “If we can do this, we can complement efforts in other sectors to stabilize the climate and deliver on the Paris agreement.”

Margaret Torn, co-head of the climate and carbon sciences program at the Lawrence Berkeley National Laboratory, said that some approaches to more climate-friendly soils management are things farmers already know how to do, but others, such as growing crops with deeper roots, aren’t available to many farmers globally.
