Figure 11. Components of total soil carbon stock change 1990-2100. Total carbon stock (in red)<br />
declines, but not as quickly as would be the case if low soil carbon land-uses (e.g. croplands) were not<br />
converted to higher soil carbon land uses (e.g. <strong>for</strong>est, woody bioenergy crops, non-woody, perennial
