英文文献摘要：
Feedstock production for large scale development of the U.S. ethanol industry and introduction of cellulose–to-ethanol technology will require extensive changes in land use and impact water demand and quality. This study compares two scenarios: attaining a 60 billion gallon per year target of ethanol by 2030 and a billion gallon per year biodiesel target by 2012 with cellulose-to-ethanol technology introduced in 2012 and also delayed until 2015. Results suggest water demands and quality will vary regionally with cellulosic feedstock production. Policy emphasis on reduced and no-till practices needs to be complementary to increased crop residue use.

美国乙醇工业大规模发展的原料生产和纤维素转化乙醇技术的引进，将需要对土地使用进行广泛的改变，并影响水的需求和质量。这项研究比较了两种情况:在2012年引入纤维素制乙醇技术(同样推迟到2015年)的情况下，到2030年实现每年600亿加仑的生物柴油目标和到2012年实现每年10亿加仑的生物柴油目标。结果表明，水的需求和质量将随纤维素原料生产的不同而不同。对减少和免耕做法的政策强调需要与增加作物残留使用相辅相成。
