Changes in Land

The additional demand for agricultural feedstock, and, consequently, agricultural cropland is expected to have an important impact in land use. These changes in land use are displayed in Figure 14. There are three major significant changes. First is the emergence of a whole new type of crop - dedicated energy crops, represented by switchgrass. Dedicated energy crops reach about 34.4 million acres by the year 2030 from very low levels in 2007. Rapid conversion of acreage into new crops is not atypical for agriculture. The most significant and recent conversion has been the case of soybeans, which expanded from near non-existence 40 to 50 years ago, to become the second most important crop in terms of acreage after corn.
