Combining Climate Science and Social Science to Develop Decision Support Toolsfor Corn Producers and Advisors (2011-2016)Linda Stalker Prokopy, PhDU2U Project Director, Associate ProfessorPurdue University5
U.S. CORN BELT• Nearly one-third of global supply• Over $50B to US economy
CurrentWork• Model the impact of climate and farm management on cropproductivity and profits– Using past and future climate scenarios• Understand beliefs and concerns about climate change andwillingness to use climate information– Surveys and focus groups (also network analysis)Models and Data Stakeholder InputDecisionSupport Tools
CropModelingandDataAnalysis• Develop an ensemble of crop models on a 4-km grid, Midwest– DSSAT, Hybrid-Maize, ISAM– Range of agronomic outcomes for various climate scenarios (past & future)• Impact of climate and management on productivity and profits– Agroclimatic trends analysis (1900-2011)– Regional ENSO analysis– NASS ‘field work days’ climatology – trends, patterns, future scenarios– Effects of crop mix, climate, etc. on capital investment decisions (case studies)Objective 1: What are the contributions of anomalous weather tocrop variability and implications for future management options?
Producer Survey• CS-CAP partnership• Mail survey of +19,000 farmers• 22 HUC6 watersheds, 60% of UScorn production• Data joined to NASS Ag CensusAdvisor Survey• Web-based survey of 8,000+ advisors– All advisors in pilot states, Extension in 12 states• Crop consultants, Extension, bankers/lawyers, agro-business, state andfederal, crop associations, etc.ClimateNeedsAssessment Surveys

Specific Tasks:(1) develop retrospective drought and wet period scenariosusing statistical modeling of DCV indices and theirassociations with hydro-meteorological variables in theBasin(2) conduct sectoral impact evaluations through use of theHydrologic Unit Model of the United States (HUMUS) andthe Erosion Productivity Impact Calculator (EPIC) driven bythe retrospective scenarios(3) Gather impact information on recent drought and wetperiods and explore potential for developing future decadalclimate outlooks with stakeholders during three regionalworkshops in Kansas City, MO; Helena, MT; and Lincoln, NEPotential Applications of Decadal Climate Predictionsin Water and Agriculture Sectors in the Missouri River BasinCody L.

Status of State Drought Planning in the U.S.
URL: http://www.drought.unl.edu/Planning/PlanningProcesses.aspxNDMC 10-Step Drought Planning Process• Created in 1990• Revised in 2005• Increased emphasison drought mitigation
• Monitoring and early warning system– assess, communicate, and trigger action– foundation of a drought mitigation plan• Vulnerability assessment– who and what is at risk and why?• Mitigation and response actions– actions/programs that reduce risk and impactsand enhance recoveryMost processes and plans in the past focused onmonitoring and responseEssential Drought Plan Components
Ex) Nebraska Municipal Water Supply, Health,and Energy SubcommitteeDrought Impact Ranking1. Municipal water supply shortages2. Rural water district mechanical problems3. Private well water quantity and quality problems4. Excessive irrigation pumping/aquifer conflicts5. Mental anguish6. Industrial users drawing down aquifers7. Health problems from blowing dust8. Temperature extremes/increased electricalusage
Colorado Drought Mitigation and Response Plan2010-2011Prepared as Drought Annex to:Colorado Natural Hazard Mitigation Plan and Emergency Operations PlanVulnerability Assessment
Inspiration:Fontaine, M., and A.C. Steinemann. 2009. Assessing vulnerability to natural hazards: Animpact-based method and application to drought in Washington State. Natural HazardsReview 10(1):11-18.
- Instream flows and hatcheries - highest impact scores are countieswith most junior water rights
Concluding thoughts…• Our assessments are largely project-based; few basin-wide• Several studies qualitative / some quantitative (or both)• Progression toward more quantitative/integrated assessments• Integration can be challenging• Integrating models and perspectives• obtaining data; identifying meaingful vulnerability metrics• Some local resistance to climate change funding andadaptation (e.g. grant proposals and farmer/advisor survey)
