Over the past three decades, tropical forest clearing and burning have greatly altered the Amazonian landscape by increasing the cover of pastures and secondary forests. The alteration of biogeochemical processes on these lands is of particular interest on highly weathered Oxisols that cover large areas in the region because of concerns regarding possible nutrient limitation in agricultural land uses and during forest regrowth. The objectives of this study were to quantify (1) the reaccumulation of nutrients in biomass of secondary land uses, (2) changes in soil nutrient contents, (3) internal nutrient cycles, and (4) input–output budgets for the landscape mosaic.
Paving the REDD road in the Brazilian Amazon
In this publication, IPAM briefly presents two on-the-ground initiatives with potential for REDD in the Brazilian Amazon that could be useful to create the basis of a National REDD regime in Brazil and, perhaps, in other tropical countries. ALENCAR, A.; CASTRO, I.;...
