Changes in the amount of carbon stored in terrestrial ecosystems are, in part, responsible for the increase in atmospheric CO{sub 2} levels, as observed since about 1750. Changes in atmospheric CO{sub 2} may affect future climate conditions. Therefore, it is important to understand both the distribution of carbon in terrestrial systems and the factors changing that distribution. There are three major sources of uncertainty in estimates of carbon release from terrestrial ecosystems due to land use changes: (1) uncertainties in rates of deforestation, land clearing, and abandonment; (2) uncertainties in estimates of the carbon in biomass of managed and unmanaged ecosystems; and (3) uncertainties in rates of change in carbon storage following conversion from one land use to another. Obtaining better quantitative estimates of these three factors will improve understanding of the effect of land use changes on the flux of carbon from the land to the atmosphere.
