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 educationalsupport 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
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
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
OBJECTIVES ATTRIBUTES ALTERNATIVES EQIP Applications 2005 Indiana EQIP Model The components of 2005 Indiana EQIP program organized in a hierarchical structure GOAL OUTCOMES
2005 Indiana EQIP Model Weights of the four National Priorities Weights are equally distributed among the sub-objectives
2005 Indiana EQIP Model • Decision rule to rank, select and enroll applications • maximizing environmental benefits considering cost-effectiveness • TS – Total Score • AS – Application score • LS – Local score • TC – Total Cost
2007 Indiana EQIP Model • National Programs Ranking Tool • To evaluate, rank and select applications for enrollment • Application Evaluation and Ranking Tool (AERT) • Based on the information in the Field Office Technical Guide • Made up of four basic components: • The Efficiency component • The National Priorities Component • The State Issues Component • The Local Issues component
2007 Indiana EQIP Model Application Evaluation and Ranking Tool (AERT) Cost Efficiency State Priorities Local Priorities National Priorities
Indiana EQIP MCDA System • The multiple criteria decision system to accommodate requirements of the Environmental Quality Incentives Program in Indiana • The issues I am addressing • Identification of goals, objectives and attributes • Development of hierarchical structure • Evaluation of applications • Incorporation of GLEAMS-NAPRA model • Weighted-additive value function method
Indiana EQIP MCDA Hierarchy • nitrate loading to surface water • phosphorus loading to surface water • nitrate loading to ground water • sediment loading • atrazine loading to surface water • atrazine loading to ground water
Indiana EQIP MCDA SystemConservation Practice Physical Effect (CPPE) Matrix • 86 eligible Best Management Practices (BMPs) • BMPs impact on environmental and natural resource problems • Same BMP – Same score
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)
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 scenarios
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.
GLEAMS - NAPRA Nitrate Loading to Surface Water After No-Till Nitrate Loading to Surface Water - Base Scenario Changes in NO3 loading between no-till scenario and base scenario Nitrate Loading to Surface Water After No-Till Nitrate Loading to Surface Water Base Scenario
EQIP 2005 Application Loading Changes Replace “categorical converted-to- quantitative” scores with changes in loadings Indiana EQIP 2005 Applications Nitrate Loadings to Surface Water Change After No-till Practice
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
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
