Introduction: Land-use change in the humid tropics leads to a net release of 1.1 to 2.1 Pg C y-1. The uncertainty in the CO2flux is from inadequate estimates of land use change, the biomass of the vegetation that is cleared, and the biomass and regrowth rates of the subsequent land use systems.ASBwas initiated in 1991 to address the agronomic, environmental, social and political implications of slash and burn agriculture. A major activity was the characterization of patterns of land clearing and subsequent land use and to quantify the changes in carbon stocks. Methods: Carbon stocks were measured in the vegetation, litter, and soils in 94 sites in Brazil, Cameroon, and Indonesia. The sites sampled in each country included undisturbed or selectively logged forests as the reference point and systems representing increasing land-use intensity.
