NRI Applications

Conservation Effects Assessment (CEAP) with the NRI

The NRI provides the scientific framework for the National Assessment component of CEAP -- the Conservation Effects Assessment Project -- an interagency effort to quantify the natural resource benefits delivered through conservation actions on private land.

The Resources Inventory & Assessment Division leads the NRI effort in cooperation with Iowa State University's Center for Survey Statistics and Methodology and support from:

• NRCS National Cartography and Geospatial Center
• NRCS Information Technology Center
