MUMBAI – It takes 2 kilolitres of water to produce 1 litre of ethanol from sugarcane, compared to 3 kl of water needed for other crops, the Indian Sugar & Bio-Energy Manufacturers Association said in a study released today. This underscores sugarcane's efficiency in converting water into economic value, it added.
The Indian Institute of Sugarcane Research, Lucknow, in collaboration with ISMA has released the first-year report of the two-year project on the study of "Improving Water Use Efficiency and Economising Water Use in Sugarcane Cultivation in India". The study is being conducted at the Indian Institute of Sugarcane Research's Lucknow, Tamil Nadu, Karnataka, Maharashtra and Madhya Pradesh centres.
The research also found that sugarcane uses a total of 1,313 cubic metres per hectare per month of water, which is less than other rival crops like maize and rice, at over 1,600 cubic metres.
The project aims to challenge the myth that sugarcane is a water-intensive crop. The research showed a comparative analysis of the total water requirement and productivity of sugarcane with other crops and its correlation with ethanol production at different locations in India, the sugar association said in a release.
Sugarcane demonstrates exceptional water utilisation efficiency, producing approximately 7.14 kg of cane per cubic metre of water, which is significantly higher than the productivity of maize, rice, and wheat, according to the research.
"The preliminary results of this study clearly highlight the efficiency of sugarcane in water utilisation and ethanol production. These findings are instrumental in demonstrating the benefits of sugarcane cultivation in terms of water conservation and productivity," Deepak Ballani, director general of ISMA said, as per the relesae.
The study reiterates that the sugarcane crop helps bring down the overall water footprint of agriculture through enhanced water use efficiency and contributes to the national and global goals of sustainability, according to the release. End
