"Modeling Soy–Corn Multicropping: A New Approach for Brazilian Agriculture" Authors: Marques Do Prado Tanure, Tarik, Angelo Gurgel, Pedro Gilberto Cavalcante Filho, Marcelo Pereira Da Cunha, Igor Lucas Rodrigues Dias, Matheus Lacerda and Danilo Garofalo Abstract Abstract This article develops a new approach to represent soy–corn double-cropping systems in Brazil within the GTAP-AEZ framework. Using a modified GTAP-AEZ v.11 database implemented in GTAPinGAMS/MPSGE for 2017, the model distinguishes between monocropping and integrated soy–corn systems, in which both crops are produced on the same land area within a single year. The framework also refines the spatial representation of Brazilian agroecological zones and updates land intensification parameters using FAO and GTAP-AEZ data. By explicitly incorporating second-crop corn, livestock feed, corn ethanol and DDG coproducts, the model improves the representation of land intensification and is expected to generate more realistic estimates of land-use change, biofuel expansion and emissions in Brazil. Keywords: double cropping; land use change; GTAP-AEZ; corn ethanol; agricultural intensification |
