The Land Institute was one of a handful of organizations asked in to submit a white paper in December 2019 to the Bipartisan Policy Center to assist in informing the House Select Committee on the Climate Crisis on the science of carbon sequestration in forests and soils. The Center was working to develop policy options related to this topic for its report, Solving the Climate Crisis, published in June 2020. This opportunity allowed TLI to share its vision of the benefits of transitioning from annual to perennial agriculture with policy makers at a high level. The paper argues that an actionable level of scientific knowledge exists right now to say that converting annual agriculture to perennial agriculture is the single most promising route to sequestering carbon in the soil, and that developing perennial grain crops is a critical and urgent step to enable fully perennializing the landscape.
