Outline• Introduction• 2005-2007 Indiana EQIP Model• Case Study: EQIP MCDA System• Results• Conclusion

Introduction• Agricultural activities contribute to numerous
environmental and resources problems
• Voluntary Federal programs (CRP, EQIP,WRP, CSP) offer technical, financial, and educational support to farm and ranch operators
• Long-term, continuing societal support depends on determining
– Positive changes directly linked to the applied conservation practices, and
– Beneficial changes are worth the large expenditures of Federal funds

Federal Conservation Programs• Reasons for this disconnect
– Voluntary program– Problematic, low productive lands– Program design
• Not including all the objectives,• Mismatched objectives and criteria, • Weighting criteria without deliberate intent,• Inappropriate criteria and scoring methods for
ranking applications
6
Multiple Criteria Decision Analysis• Provides guidance and structure• Leads to well-documented, reproducible
decisions• Encourages precise explanations of a
decision maker’s values and beliefs and the trade-offs
• Can be used to assess and evaluate environmental policies and programs
7
Objectives• Incorporate the broader, formal decision
system and its associated framework• Structure
• Generic specification
• Correct several flaws through adoption of multiple criteria decision analysis procedures, methods, and tools
• Integrate hydrologic simulation models to reintroduce spatial heterogeneity and quantitative attributes

Indiana EQIP MCDA System Measurement of Attributes
• The hydrologic simulation models– Quantify the loadings of pollutant before and
after implementation of BMPs– Consider heterogeneous physical conditions,
climate, and BMPs– Produce the amount changes of major
pollutants• Groundwater Loading Effects of Agricultural
Management Systems - National Agricultural Pesticide Risk Analysis (GLEAMS-NAPRA)
27
Indiana EQIP MCDA System Measurement of Attributes - Scenarios• Base scenario – No BMPs have been applied• Remaining scenarios
– Residue Management/No-Till– Filter Strip– Nutrient Management
• Before BMP – 222 N kg/ha and 125 P2O5 kg/ha • After BMP – Tri-State Recommendation
– Pest Management• Before BMP – 2 lb/ac• After BMP – 1.5 lb/acre or incorporation
• Totally 16 scenarios28
Indiana EQIP MCDA System Measurement of Attributes
• Six Outcomes:– nitrate loading to surface water, – phosphorus loading to surface water, – nitrate loading to ground water, – sediment loading, – atrazine loading to surface water and – atrazine loading to ground water.

Conclusion• Design and assessment of Federal
conservation programs following MCDA approach– Improve program performance by enrolling more
cost efficient applications– Minimize common flaws
• Mismatched objectives and criteria, • Weighting criteria without deliberate intent,• Inappropriate criteria and scoring methods for ranking
applications – Reintroduce spatial heterogeneity– Identify problematic nonpoint-source areas
34
Next• Replace the “categorical-converted-to-
quantitative” scores• Calculate application’s overall value• Score and rank applications• Distribute available program funds • Compare MCDA system with actual EQIP
2005 program– Number and type of applications– Location of applications– Estimated environmental benefits
