The model was based on a set of four representative house-holds occupying four distinct agroecological zones. Households in the model were assumed to choose crop shares, defined over a portfolio of subsistence food crops, annual and perennial cash crops, to maximize a mean-variance utility function.text/plainen-USIn CopyrightEconomic policyWatershed managementEconomic modeling and analysisSustainable developmentGovernanceAbstractCopyright 2005 CAB International
