This study analyzes the long-term impacts of large-scale expansion of biofuels on land-use change, food supply and … lands in a few countries. The results also suggest that the expansion of biofuels would cause a reduction in food supply …. Although the magnitude of the impact on food supply at the global level is not as large as perceived earlier, it would be …
