National Bulletin: NB 290-22-2 Date: November 8, 2021
Subject: INV - Peer Review of Conservation Effects Assessment Project (CEAP) Conservation Benefits Indicator (CCBI) Field Level User Guide 1.0 for NRCS Staff Use


 

Purpose.  To announce the Agency peer review of the CEAP Conservation Benefits Indicator (CCBI) Field Level User Guide 1.0 and web application.   

 

Expiration Date.  October 30, 2022

 

Background.  Since 2009, the CCBI has shown that it can be a simple, fast screening tool for conservation planners. The tool helps planners “screen” or quickly identify farmers’ fields most vulnerable to losses of sediment, crop nutrients, and pathogens. Such screening helps prioritize the allocation of future NRCS conservation resources by ranking conservation needs within a given geographic region.

Over the past decade, the Resource Inventory and Assessment Division has worked to improve rulesets and access to the most up-to-date soil vulnerability index for cultivated cropland (SVI-cc) enterprise data layer. The CCBI builds on the SVI-cc by ranking fields according to their inherent vulnerabilities and intersecting those vulnerability levels with the conservation practices applied since 2005 that meet avoid, control and trap (ACT) criteria to identify where practices have been applied and where potential needs exist. The CCBI Field Level tool is intended to help NRCS staff prioritize conservation management choices to minimize loss of excess agricultural nutrients, chemicals, and pathogens into surface and ground water (including drinking water source areas) based on local soil landscape limitations. The current release uses FY 2020 USDA NRCS detailed soil survey geographic database, FY 2019 CEAP cultivated cropland information, agency conservation histories, and related landscape attributes. When agency infrastructure allows, these products will be updated with current fiscal year soil and cropland data.

 

Explanation.  The CCBI web application was created to visualize potential treatment needs at the field level. The user guide provides a step-by-step description on how to use the web application and basic information about how CCBI Field Level datasets were prepared. The user guide also provides definitions of terms, data sources, CCBI Field Level rulesets, GIS processing steps, example calculations, citations, and selected references. We are asking States to review both the web application and user guide to help us improve them.

The CCBI Field Level Web App is available through the Geoportal. Quick Start instructions are provided in Appendix A of the User Guide. Appendix B provides instruction on completing peer review questions. Appendix C provides the listing of conservation practices that meet ACT criteria.

Attachment A provides a full copy of the CCBI Field Level User Guide 1.0.
