How much does loss of organic matter in soil (due to land degradation) contribute to national CO2 emissions; how much fixation will result from intensification of agriculture and conservation?

Land degradation is a widespread phenomenon in which large quantities of C are involved. Its contribution to national C-balances has not been quantified.
Explicit knowledge of this aspect of land degradation may stimulate government interest in the value of land, which is often one of the main assets of poor farmers.
