What drives intensification of land use at agricultural frontiers in the Brazilian Amazon? evidence from a decision game.
Land-use change results from the decisions of diverse actors in response to economic and political contexts. Identification of underlying decision-making processes is key to understanding land-use patterns, anticipating trends, and designing effective environmental governance mechanisms. Here, we us...

Desafios para a consolidação de um sistema de alerta de risco de desastre associado à secas no Brasil.
No Brasil, a seca é um fenômeno caracterizado pela sua ampla cobertura espacial e recorrência na região semiárida, principalmente devido à sua vulnerabilidade hídrica. Quase 28 milhões de pessoas vivem na região, que concentra a maior parte da população mais pobre do Brasil. Assim, a seca...

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...

Monitoring of soil moisture for drought risk assessment over the Brazilian semiarid region.
Soil moisture is being monitored over the Brazilian semiarid since 2014 using a network of 595 stations. The network was implemented by Cemaden, the National Center for Monitoring and Early Warning of Natural Disasters, with the objective of monitoring of spatial and temporal patterns of soil water ...

Net ecosystem exchange and evapotranspiration in a contrasting climate and land-use conditions in a tropical deciduous dry forest in Brazil.
The largest single block of seasonally dry forest in the world is the Caatinga biome found in northeastern Brazil. It covers 844,453 km2 and houses a high level of endemic plant species adapted to the low precipitation (400-800 mm year-1), high mean air temperature (26-28 oC), and elevated potential...

Changes in the Amazon and Brazilian Cerrado’s water resources due to land use change in the last 40 years.
Understanding how land use change can affect natural dynamics of water resources in Amazon and Brazilian Cerrado is of importance due to the constant pressure for deforestation suffered by these biomes. In this work, the dynamic vegetation model with river routing and flood dynamics INLAND-THMB (Int...

Soil moisture variation along a toposequence in the northeast Brazilian caatinga.
Soil moisture variations and soil water potentials are crucial to understand the plant behavior under water stress conditions. Such kind of data are also valuable for modeling efforts in hydrology, ecophysiology, soil-plantatmosphere interactions and earth system models. Here we present soil moistur...

Exposure assessment of rainfall to interannual variability usingthe wavelet transform.
It is generally accepted that El NiñoSouthern Oscillation (ENSO) is the main modulator of rainfall variability over Northern South America in the interannual scale. Assuming that, an index is proposed to quantify this expected interannual variability in time series of rainfall. The result is the ex...

Response of the river discharge in the Tocantins River Basin, Brazil, to environmental changes and the associated effects on the energy potential.
Climate change is expected to impact the hydrological regime worldwide, and land use and land cover change may alter the effects of the former in some cases. Secondary growth in deforested and abandoned areas is one of the main consequences of land use and cover changes in Amazonia. Among land uses,...
