Este perfil paÍs presenta una descripción detallada de las GTT en Brasil a partir de datos extraídos utilizando filtros regionales del sitio web de Land Matrix. En algunos casos, se incluyeron transacciones que cumplían con criterios diferentes a los de la base de datos global, tales como aquellas transacciones de alcance meramente nacional o doméstico.
This paper presents a new approach for rapidly assessing the extent of land use and land cover (LULC) areas in Mato Grosso state, Brazil. The novel idea is the use of an annual time series of fraction images derived from the linear spectral mixing model (LSMM) instead of original bands.
Este livro trata da história da Amazônia desde a chegada do homem no vale do Amazonas há mais ou menos 11000 a.C. até os dias atuais. Nele você vai poder compreender os períodos históricos seguindo a linha do tempo, a qual marca com ícones os acontecimentos mais importantes na região. Os textos do livro estão intercalados por ilustrações que representam cada época.
Land-use change (LUC) is a complex process that is difficult to project. Model collaboration, an aggregate term for model harmonization, comparison and/or coupling, intends to combine the strengths of different models to improve LUC projections. Several model collaborations have been performed, but to the authors’ knowledge, the effect of coupling has not been evaluated quantitatively.
Brazil has become an agricultural powerhouse, producing roughly 30 % of the world’s soy and 15 % of its beef by 2013 – yet historically much of that growth has come at the expense of its native ecosystems. Since 1985, pastures and croplands have replaced nearly 65 Mha of forests and savannas in the legal Amazon.

Demand for agricultural exports in Brazil has stimulated the expansion of crop production and cattle raising, which has caused environmental impacts. In response, Brazil developed public policies such as the new Forest Code (FC) and supply chain arrangements such the Soy and the Cattle Moratoriums.
Growing domestic and international ethanol demand is expected to result in increased sugarcane cultivation in Brazil. Sugarcane expansion currently results in land-use changes mainly in the Cerrado and Atlantic Forest biomes, two severely threatened biodiversity hotspots. This study quantifies potential biodiversity impacts of increased ethanol demand in Brazil in a spatially explicit manner.
