This study investigates the water scarcity implications of bioethanol production in Negros Occidental, Philippines. The water footprint (WF) of three bioethanol production scenarios was assessed, revealing respective values of 3,574 L L-1, 3,935 L L-1, and 4,293 L L-1 for Case 2 (molasses bioethanol), Case 3 (50% sugarcane and 50% molasses bioethanol), and Case 1 (sugarcane bioethanol). Predominantly, 99% of the total WF comes from sugarcane plantation activities, with the blue WF (freshwater use) accounting for a mere 1.3%, owing to predominantly rainfed sugarcane farms. Region VI, encompassing Negros Occidental, faces severe blue water scarcity at 41%, with projections indicating exacerbation unless water footprint mitigation strategies are implemented. Notably, the contribution of the bioethanol industry to the total WF of the region is only about 0.1%. Sensitivity analysis for varying sugarcane yield done revealed that increasing yield from 65 t ha-1 to 115 t ha-1 can significantly reduce WF to about 43%. This research underscores the need for water-efficient practices to address potential water scarcity of the region, while emphasizing the limited water scarcity impact of bioethanol industry.
