| Abstract | The 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). |
