The article reports on the significant losses[/INST] R$500 million suffered by Brazilian sugarcane plantations due to fires, with an additional R$500 million loss expected from drought. The drought, which has increased production costs and led to a 12% decrease in sugarcane harvest expectations, has also caused the value of ethanol and sugar futures to surge on the New York Stock Exchange. The fires have affected production in several states, necessitating rapid harvesting or replanting of affected crops. The article also highlights an agreement in São Paulo, signed in 2007, that banned the practice of burning sugarcane straw, which was previously common but now contributes to the losses.
