Continuing the earlier post, below is Figure 3 from “Our share of the planetary pie,” a paper from the Proceedings of the National Academy of Sciences in 2007. The upper map shows the percentage of net primary productivity used by humans for food; the lower map shows the percentage of net primary productivity (NPP) used by humans for non-food and luxury crops such as cotton and coffee. See Figure 1 at the link for a map showing croplands and pastures.
A few things worth noting: compare human appropriation of net primary productivity (HANPP, the biosphere bounty humans skim off before flora and fauna can get it) in the US Northwest and Europe. Look at the equatorial regions, where most biofuel-related land use changes have and would occur and where most biodiversity lives. Look at Borneo, the big island northwest of Australia: the purple in the lower map probably represents palm oil plantations, which result in nearly 100% HANPP where they occur. In general, areas with no HANPP are tropical, temperate, or boreal forest, arctic/antarctic regions, or desert.
