【 摘 要 】

Deforestation often results in massive carbon emissions and loss of ecosystem services. The objective of this paper is to develop an integrated approach to quantitatively derive changes in forest carbon stock and changes in the economic value of forest carbon due to deforestation. Combining the best available remote sensing and socioeconomic datasets, this approach establishes a comprehensive baseline of deforestation in terms of area, carbon and monetary value change. We applied this end-to-end evaluation method in the Brazilian state of Rondonia to assess the ecological and economic effects of its recent deforestation from 2000 to 2005. Our results suggest that deforestation occurred at an average rate of 2834 km2/yr during the study period, leading to 31 TgC/yr "committed carbon emissions" from deforestation. Coupling with the social cost of carbon at $23/tC and a market discount rate at 7%, this translates to $622 million U.S. dollars/yr loss in the economic value of forest carbon.
