Learn about the History of the Network
Until 1988, sugar and ethanol production in Brazil was heavily regulated and subsidized by the Federal Government. With the enactment of the new federal constitution in 1988, a new economic policy framework was established, ending subsidy programs, including PROÁLCOOL. Consequently, all incentives for sugarcane research, including genetic improvement, were halted with the dissolution of the IAA in 1990, and consequently, the PLANALSUCAR agency was shut down. That same year, the incorporation of units of the defunct PLANALSUCAR by Federal Universities opened new perspectives for both researchers and the sugarcane sector.
