Modeling South America regional smoke plume: aerosol optical depth variability and shortwave surface forcing.
Intra-seasonal variability of smoke aerosol optical depth (AOD) and downwelling solar irradiance at the surface during the 2002 biomass burning season in South America was modeled using the Coupled Chemistry-Aerosol-Tracer Transport model to the Brazilian developments on the Regional Atmospheric Mod...

Climate change in Brazil: perspective on the biogeochemistry of inland waters.
Although only a small amount of the Earths water exists as continental surface water bodies, this compartment plays an important role in the biogeochemical cycles connecting the land to the atmosphere. The territory of Brazil encompasses a dense river net and enormous number of shallow lakes. Human ...

Overcoming barriers to collective action in community-based fisheries management in the Amazon.
A set of freshwater fisheries management institutions in the central Brazilian Amazon leads us to propose an expansion of the common pool resource (CPR) management models developed by Ostrom. We analyze the origins and effectiveness of a community-based CPR system that has emerged despite several fe...

Nitrogen mass balance in the Brazilian Amazon: an update.
The main purpose of this study is to perform a nitrogen budget survey for the entire Brazilian Amazon region. The main inputs of nitrogen to the region are biological nitrogen fixation occurring in tropical forests (7.7 Tg.yr -1), and biological nitrogen fixation in agricultural lands mainly due to ...

Extreme climatic events in the Amazon basin: climatological and hydrological context of recent floods.
During 2009 the Amazon basin was hit by a heavy flooding with a magnitude and duration few times observed in several decades. Torrential rain in northern and eastern Amazonia during the austral summer of 20082009 swelled the Amazon River and its tributaries. By July 2009, water levels of the Rio Neg...

Development of regional future climate change scenarios in South America using the Eta CPTEC/HadCM3 climate change projections: climatology and regional analyses for the Amazon, São Francisco and the Parana River basins.
The objective of this study is to assess the climate projections over South America using the Eta-CPTEC regional model driven by four members of an ensemble of the Met Office Hadley Centre Global Coupled climate model HadCM3. The global model ensemble was run over the twenty-first century according ...

The carbon balance of South America: status, decadal trends and main determinants.
We review the carbon balance and trends over the last decades, as well as their determinants, for South America as part of a catalogue of similar regional syntheses covering the globe for the RECCAP (REgional Carbon Cycle Assessment and Pro- 5 cesses) effort. South America as a region has attracted ...
