The National Assessment

Purpose: Quantify environmental effects andand benefits of conservation practices for national and regional reporting

Page 3: Status of the CEAP National Assessment

Goals

1. Estimate the benefits of conservation practices currently present on the landscape

2. Estimate the need for conservation practices and the benefits that could be realized under “full treatment”

3. Simulate alternative options for implementing conservation programs in the future

4. Incorporate estimates of practice benefits into the Agency’s annual Performance Reporting System

Cropland ComponentTwo Levels of Effects

Field-Level Effects (Onsite)– Productivity and sustainability Productivity and sustainability

– Reduction of potential pollutants Reduction of potential pollutants leaving farm fieldsleaving farm fields

Off-Site Effects– Reduction in water quality impairmentReduction in water quality impairment– Reduction in air quality impairmentReduction in air quality impairment

Analytical Approach

Sampling and modeling approach – About 20,000 NRI cropland sample points and About 20,000 NRI cropland sample points and

about 12,000 NRI CRP sample points will be used about 12,000 NRI CRP sample points will be used to construct the modelto construct the model

Farmer Survey– National Agriculture Statistical Service (NASS) National Agriculture Statistical Service (NASS)

conducting voluntary farmer surveys at the 20,000 conducting voluntary farmer surveys at the 20,000 cropland sample points. cropland sample points.

Physical process model (APEX) Off-site water quality benefits

Modeling Strategy

1. Estimate a CEAP Baseline using farmer survey information

2. Construct an alternative scenario assuming “no practices”

Difference between these two scenarios represents the benefits of the accumulation of conservation practices currently in place.

Wildlife Component

Page 13: Status of the CEAP National Assessment

Wildlife Component Approach

• Work collaboratively with others already engaged in relevant assessments

• Use existing data wherever possible

• Identify critical data gaps and take steps to fill them

• Based on regional priorities
