Avoided Conversion of Grasslands and Shrublands to Crop Production

2.0

Version 2.0 of ACR's Avoided Conversion of Grasslands and Shrublands to Cropland Production (ACoGS) methodology is currently open for public comment.  The revised methodology is posted below along with the summary of changes since version 1.0. 

The updated methodology was developed with Ducks Unlimited and The Nature Conservancy, with financial support provided by a USDA NRCS Conservation Innovation Grant. Multiple revisions have been proposed in version 2.0 of the methodology to make it simpler to use, better aligned with conservation programs, and reflecting the latest trends in conversion.

The methodology quantifies the emissions avoided from preventing the conversion of grasslands and shrublands to commodity crop production in the U.S. Grassland and shrubland soils are significant reservoirs of organic carbon that, if left uncultivated, will continue to store this carbon below ground. Grassland and shrubland ecosystems may also support greater plant biomass than annual cropland, especially below ground. In addition to the avoided cultivation and oxidation of soil organic carbon, several crop production practices, such as fertilizer application, may also be avoided. Livestock, primarily cattle, are anticipated to be common in the project scenario and their associated emissions from enteric fermentation and manure deposition are accounted for. 

Please submit questions and/or comments to through November 18, 2018.
