Abstract

Sugarcane-based bioenergy systems are critical in Brazil's renewable energy sector, contributing significantly to global efforts to reduce fossil fuel dependence. However, climate change introduces uncertainties related to sugarcane yield, water use efficiency, and greenhouse gas emissions. Rising atmospheric carbon dioxide (CO2) levels, increasing temperatures, and shifts in precipitation patterns are expected to impact Brazil's bioenergy cultivated areas, necessitating a comprehensive evaluation of their effects on sugarcane production and environmental sustainability.
