15. Carvão vegetal e siderurgia: de elo perdido a solução para um mundo pós-Kyoto / Charcol based iron &steelmaking: from primitive technological model to solution for a post-Kyoto world
In a global-warming-frightened world, the positive carbon balance of charcoal-based iron &steel making recovers it from a past outshined by the dominance of the large fossil fuel mills. Nevertheless, the risk of not being able to profit from the global decarbonization consensus is material, owing to the dependency on deforestation. This is true even being th

17. Changes in the soil carbon stocks due to agricultural land use in the Southwest Amazonian / Mudança no estoque de carbono do solo devido ao uso agrícola da terra no Sudoeste da Amazônia
Land use changes such as conversion of natural ecosystems to agro ecosystems are shown to cause alterations in the transformations of soil organic matter (SOM), as well they are responsible for crescent emissions of greenhouse gases (GEE), therefore representing around 20% of total GEE emissions. Over the last 30 years, land deforestation has occurred more i

20. Alterações no estoque e taxa de sequestro de carbono em um Latossoto vermelho submetido a sistemas de manejo.
The objective of this study was to quantify the changes of the total carbon (C) and total nitrogen (N) stock, and the variation of the C pools in monthly soil samples, and the C balance and C sequestration rates provoked by the soil tillage systems. The soil samples were accomplished in a long term experiment implanted in 1988, in the experimental station of
