Carbon mitigation payments can reduce the riskiness of bioenergy crop production

Abstract

Perennial bioenergy crops provide substantial carbon mitigation benefits but have risky returns. We couple economic analysis with a biogeochemical model (DayCent) to examine the effect of carbon mitigation payments on the spatially varying bioenergy crop returns and risk profiles relative to conventional crops across the rainfed United States. These payments increase the likelihood of positive profit in the Midwest for miscanthus and southern states for switchgrass. At low biomass prices, these payments make bioenergy crops appealing to risk-averse farmers. At moderate biomass prices, these payments make bioenergy crops appealing to all farmers regardless of risk preference.
