We are talking about an industry which competitiveness is historically attached to a slaver structure. Up to current times there are serious issues regarding the labor conditions at sugarcane crops, not to mention atmospheric emissions due to the burning process that precedes harvesting and soil & water pollution due to the use of agrochemicals.
I would see investigation assessing in which context(s) this industry would be [really] sustainably competitive. I mean, considering fair remuneration for employees throughout the value chain; accounting for the greenhouse gases (GHG) emissions due to exports, transportation of inputs, employees and products, and the use of petrochemical fertilizers; and seriously considering the issue of subsidies and other governmental incentives.
Is it really market competitive? Would it be someday?
Because up to know we only had years of transfer of population money (payment of taxes and tariffs) to the pocket of sugarcane farmers and sugar and ethanol producers through the governmental policies.
