Description:
Tropical evergreen forests (TEF) of southeast Mexico experienced a deforestation rate of approximately 206,000 ha/yr and an efflux of nearly 21 TgC/yr between 1980 and the present. and formerly occupied by these forests have potential to mitigate greenhouse gas emissions. his paper examines the effects of two TEF management scenarios in the eight-state region of southeast Mexico and the effects on CO2 mitigation. e also modeled two scenarios to examine possible adjustments to the region's -flux estimate by accounting for regrowth of degraded forests and increase of C stocks in mature forests. otential TEF distribution in the study area and current data from a Mexican forest inventory are compared to calculate areas available for modeling land-based C flux and mitigation options. imple spreadsheet model was developed to evaluate possible C conservation through reforestation and reduced deforestation as well as improvements to the region's C-flux estimates from degraded land regrowth and C accretion in mature forests. otal C flux modeled in the four scenarios totaled up to 29 TgC/yr, and illustrates the significant impacts that land management may have on carbon balance estimates and accounting for a portion of the missing global carbon sink.
