ResumoIn tropical areas, pioneer occupation fronts steer the rapid expansion of deforestation, contributing to carbon emissions. Up-to-date carbon emission estimates covering the long-term development of such frontiers depend on the availability of high spatialtemporal resolution data. In this paper, we provide a detailed assessment of carbon losses from deforestation and potential forest degradation from fragmentation for one expanding frontier in the Brazilian Amazon. We focused on one of the Amazonias hot-spots of forest loss, the BR-163 highway that connects the high productivity agricultural landscapes in Mato Grosso with the exporting harbors of the Amazon. We used multidecadal (19842012) Landsat-based time series on forested and non-forested area in combination with a carbon bookkeeping model. We show a 36% reduction in 1984s biomass carbon stocks, which led to the emission of 611.5 TgCO2 between 1985 and 1998 (43.6 TgCO2 year-1 ) and 959.8 TgCO2 over 19992012 (68.5 TgCO2 year-1 ). Overall, fragmentation-related carbon losses represented 1.88% of total emissions by 2012, with an increasing relevance since 2004. We compared the Brazilian Space Agency deforestation assessment (PRODES) with our data and found that small deforestation polygons not captured by PRODES had increasing importance on estimated deforestation carbon losses since 2000. The comparative analysis improved the understanding of data-source-related uncertainties on carbon estimates and indicated disagreement areas between datasets that could be subject of future research. Furthermore, spatially explicit, annual deforestation and emission estimates like the ones derived from this study are important for setting regional baselines for REDD? or similar payment for ecosystem services frameworks.

ResumoThe distribution of sources and sinks of carbon among the world's ecosystems is uncertain. Some analyses show northern midlatitude lands to be a large sink, whereas the tropics are a net source(1); other analyses show the tropics to be nearly neutral. whereas northern mid-latitudes are a small sink(2,3). Here we show that the annual flux of carbon from deforestation and abandonment of agricultural lands in the Brazilian Amazon was a source of about 0.2 g C yr(-1)over the period 1989-1998 (1 Pg is 10(15)g). This estimate is based on annual rates of deforestation and spatially detailed estimates of deforestation, regrowing forests and biomass. Logging may add another 5-10 percent to this estimate(4), and fires may double the magnitude of the source in years following a drought(4), The annual source of carbon from land-use change and fire approximately offsets the sink calculated for natural ecosystems in the region(5,6). Thus this large area of tropical forest is nearly balanced with respect to carbon, but has an interannual variability of +/- 0.2 PgC yr(-1).

ResumoThe Brazilian Amazon is a hotspot of deforestation and forest degradation caused by logging, fire, and deforestation-associated fragmentation and edge effects. While the extent of deforestation and associated carbon losses are relatively well known, the quantification of the carbon losses caused by degradation and the carbon gained by recovery of degraded forest ranges widely. We present a detailed analysis of forest changes and associated carbon gains and losses by using repeated randomized airborne lidar surveys for 2016 and 2017 over 102 different transects covering more than 50,000 ha throughout the Brazilian Arc of Deforestation . We directly measured changes in canopy height and used previously calibrated allometric equations to estimate aboveground carbon changes. After gridding the surveyed area to 50 m x 50 m, we found that 21.6% of the area analyzed suffered losses in canopy height that exceeded 0.5 m, while only 16.3% of the area had canopy height recovery higher than 0.5 m. This translates to an annual carbon loss of 102.8 GgC, while carbon gained through forest regrowth was 33.4 GgC. Canopy height losses that exceeded 5 m accounted for 6.1% of the loss area identified but were responsible for 28.3% of the total aboveground carbon loss. When separated according to legally protected status, carbon changes on loss areas averaged -7.1 ± 7.6 (standard deviation) MgC/ha-y inside indigenous territories, -9.8 ± 13.0 MgC/ha-y within conservation units and -10.1 ± 12.1 MgC/ha-y outside the two protected categories. Carbon changes in gain areas averaged 4.0 ± 1.8 MgC/ha-y with no discernible differences among the three categories. To attribute carbon losses to different degradation drivers, we trained a machine learning model based on lidar point cloud metrics and visual interpretation of high resolution satellite imagery to differentiate between multiple types of deforestation and forest degradation (e.g. logging, fire). Extrapolating the results to the extent of the Arc of Deforestation represented by our randomized airborne campaigns, we find that forest degradation would account for a substantial portion of Brazilian carbon emissions were it considered in national budgets. Our study presents one of the first large-scale quantifications of carbon losses due to forest degradation from logging and fire.

ResumoWe present a generic spatially explicit modeling framework to estimate carbon emissions from deforestation (INPE-EM). The framework incorporates the temporal dynamics related to the deforestation process and accounts for the biophysical and socioeconomic heterogeneity of the region under study. We build an emission model for the Brazilian Amazon combining annual maps of new clearings, four maps of biomass and a set of alternative parameters based on the recent literature. The most important results are: (a) Using different biomass maps leads to large differences in estimates of emission; for the entire region of the Brazilian Amazon in the last decade, emission estimates of primary forest deforestation range from 0.21 to 0.26 PgCyr−1. (b) Secondary vegetation growth presents a small impact on emission balance because of the short duration of secondary vegetation. In average, the balance is only 5% smaller than the primary forest deforestation emissions. (c) Deforestation rates decreased significantly in the Brazilian Amazon in recent years, from 27 Mkm2 in 2004 to 7 Mkm2 in 2010. INPE-EM process-based estimates reflect this decrease even though the agricultural frontier is moving to areas of higher biomass. The decrease is slower than a non-process instantaneous model would estimate as it considers residual emissions (slash, wood products and secondary vegetation). The average balance, considering all biomass, decreases from 0.28 in 2004 to 0.15 PgCyr−1 in 2009; the non-process model estimates a decrease from 0.33 to 0.10 PgCyr−1. We conclude that the INPE-EM is a powerful tool for representing deforestation-driven carbon emissions. Biomass estimates are still the largest source of uncertainty in the effective use of this type of model for informing mechanisms such as REDD+. The results also indicate that efforts to reduce emissions should focus not only on controlling primary forest deforestation but also on creating incentives for the restoration of secondary forests.
