Assessing the possible impacts of a 4 °C or higher warming in Amazonia.

The Amazonian forest’s ability to provide environmental services is threatened by anthropogenic forcing at various scales, such as deforestation, fire, global and regional climate change, and extreme events. In addition to the impacts resulting from each one of these drivers, the synergistic effec...

Land use and land cover transition in Brazil and their effects on greenhouse gas emissions.

Changes in natural environments caused by human activities through land use and land cover changes (LUCC) have increased during the last three centuries. LUCC is a key sector of climate change, and it is responsible for an important amount of greenhouse gas (GHG) emissions. Agriculture, Forestry, an...

Methods to evaluate land-atmosphere exchanges in Amazonia based on satellite imagery and ground measurements

During the last three decades, intensive campaigns and experiments have been conducted for acquiring micrometeorological data in the Amazonian ecosystems, which has increased our understanding of the variation, especially seasonally, of the total energy available for the atmospheric heating process ...

Estoques de carbono orgânico em argissolo vermelho-amarelo sob diferentes sistemas de manejo e uso da terra (suts).

A substituição de ecossistemas naturais por sistemas agropecuários resulta, frequentemente, no declínio do teor de carbono (C) orgânico do solo, em função da redução do aporte, perdas por erosão e da taxa de decomposição da matéria orgânica. Baseando-se neste contexto, este trabalho t...
