Technical Abstract: Large-scale biofuels development as a source of renewable energy will shift current dynamics in the agricultural sector that deliver food, feed, and fiber. This chapter examines the potential for modern agriculture to support a biofuels industry without comprimising its critical role for delivering food, feed, and fiber. Four key questions are examined. They are: (1) Does enough land exist to sustainably produce large quantities of biofuels in addition to that needed to meet increasing demand for food, feed, and fiber?; (2) Are the physical and geoclimatic attributes of land bases adequate to support and sustain biofuel production?; (3) How do existing agricultural production systems economically integrate biofuels production?; and, (4) What is the sustainable vision for the next-generation agricultural sector? We conclude that: (1) Sufficient land is available for increased agricultural production including crops for biofuel, but the land is disappropriately located; (2) Biofuels production will have some effect on land use change, but other factors such as changing food consumption patterns are likely to be more detrimental than producing biofuel feedstocks; and, (3) There are strategies worthy of investigation, such as integrated cropping systems, that could not only mitigate potential negative impacts, but also enhance overall sustainabilty. Finally, an integrated landscape vision is presented to illustrate that there is enough land for biofuel production without impacting food, feed, and fiber availability provided the entire agricultural system is operated using sustainable, well-managed strategies and practices.
