Amazonian forests continuously accumulate carbon (C) in biomass and in soil, representing a carbon sink of 0.42?0.65 GtC yr−1. In recent decades, more than 15% of Amazonian forests have been converted into pastures, resulting in net C emissions (~200 tC ha−1) due to biomass burning and litter mineralization in the first years after deforestation. However, little is known about the capacity of tropical pastures to restore a C sink. Our study shows in French Amazonia that the C storage observed in native forest can be partly restored in old (≥24 year) tropical pastures managed with a low stocking rate (±1 LSU ha−1) and without the use of fire since their establishment. A unique combination of a large chronosequence study and eddy covariance measurements showed that pastures stored between −1.27 ± 0.37 and −5.31 ± 2.08 tC ha−1 yr−1 while the nearby native forest stored −3.31 ± 0.44 tC ha−1 yr−1. This carbon is mainly sequestered in the humus of deep soil layers (20?100 cm), whereas no C storage was observed in the 0- to 20-cm layer. C storage in C4 tropical pasture is associated with the installation and development of C3 species, which increase either the input of N to the ecosystem or the C:N ratio of soil organic matter. Efforts to curb deforestation remain an obvious priority to preserve forest C stocks and biodiversity. However, our results show that if sustainable management is applied in tropical pastures coming from deforestation (avoiding fires and overgrazing, using a grazing rotation plan and a mixture of C3 and C4 species), they can ensure a continuous C storage, thereby adding to the current C sink of Amazonian forests.

The global interest in biofuels has increased significantly in recent years, mainly due to the concern about climate change. In Brazil, the land area under sugarcane cultivation has expanded in unprecedented ways to meet the increasing ethanol demand of both the domestic and international markets. São Paulo is the Brazilian state with the highest production of sugarcane, and the expansion of this activity can impact both the environment and society. The purpose of this paper was to assess and map the sensitivity of the areas used for sugarcane cultivation in São Paulo state and to provide a holistic approach to sugarcane production from the sustainability perspective by integrating indicators of the environmental, social and economic spheres without focusing on one single element. Five environmental indicators (related to water resources, slope, environmental conservation areas, land use and agricultural potential) and six socioeconomic indicators (related to employment, income, education, gender equality, child labor and forced labor) were selected for the analysis. The methodology comprised the Categorical Principal Components Analysis (CATPCA) technique and the spatialization of results in a Geographic Information System. The resulting maps of sensitivity show the patterns of the three retained principal components and provide an information-rich tool that the government can use in decision making, policy formulation and the integrated planning of land use, thereby enabling the identification of both hotspots and which issues should be prioritized.
