This study analyzes the production of biogas from the anaerobic digestion of energy crops, and the authors address concerns about potential negative effects on the environment, on competition in the food market, and the progressive changes in land use. In particular, they investigate the trade-offs between water use and bioenergy production by integrating “water footprint and life cycle assessment” methodologies for three different geographical locations (northern, central and southern Italy) and crops (maize, sorghum and wheat.)
