2. Research Problem: Meeting the demands for FEW while reducing multiple environmental externalities - - incorporating the potential for emerging productivity enhancing technologies (cellulosic biofuels, big data enabled precision farming) and designing policy incentives.Scale of analysis: Microunit of analysis in behavioral models vs ecosystem modelsTrade-off between heterogeneity and overall geographical scale of analysis Technological change: Dynamic and spatially heterogeneousInvolves lumpy, indivisible investmentsAffected by non-economic behavioral factors; Risk, uncertainty, adaptive expectations and absence of perfect foresightModeling multiple externalities requires linking more than one type of biophysical/hydrological model (SWAT, DayCent, GREET) with economic modelConsistency across modelsDesigning mix of policy instruments that achieve multiple environmental objectives that are complements/conflictingUncertainty due to natural variability: Implications for policy
