increase carbon above ground if farmers plant significant numbers of trees
(the success of which depends on rainfall ). If overgrazing converts grassland to
bushland, then above-ground carbon will increase, but below-ground effects are
unknown. In addition, rangelands are a significant carbon sink (IPCC, 2000),
but the potential of these areas for further sequestration is not clear.
