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.

Indigenous Peoples and the Reducing Emissions from Deforestation and Forest Degradation (REDD+) mechanism in the Brazilian Amazon – Subsidies to the Discussion of Benefits Sharing

The purpose of this publication is to provide a better understanding on the contribution of indigenous perspectives to the discussion of REDD+ benefit sharing, based on some indig- enous’ points of view and experiences of the Amazon indigenous peoples in Brazil. More specifically, the aim from a participatory and consultative process is to provide support for the construction benefit sharing models for REDD+ programs, which actually promotes inclu- sion of these people, focusing on the Brazilian context.
