Relationship between the streamflows and precipitations in Itapemirim River Basin.
The present paper analyzed the relationship between streamflow and rainfall at the stream of Itapemirim River Watershed (BHRI). The minimum streamflow with duration of seven days (Q7), the average annual streamflow (Qmed) and the annual maximum streamflow (Qmax) of 11 BHRIs sub-basins were determine...

Fire responses to the 2010 and 2015/2016 Amazonian droughts.
Extreme droughts in Amazonia cause anomalous increase in fire occurrence, disrupting the stability of environmental, social, and economic systems. Thus, understanding how droughts affect fire patterns in this region is essential for anticipating and planning actions for remediation of possible impac...

Evaluating monetary-based benefit-sharing as a mechanism to improve local human development and its importance for impact assessment of hydropower plants in Brazil.
Although hydropower companies and governments have promoted monetary-based Benefit-Sharing Mechanisms alone as a vector of local development for flooded municipalities, it is not possible to identify this evidence in the scientific literature. The present work investigates the quantitative influence...

First measurements of the ocean-atmosphere CO2 fluxes at the Cabo Frio upwelling system region, Southwestern Atlantic Ocean.
This study presents novel results about ocean-atmosphere CO2exchanges based upon novel directin situmea-surements of turbulentfluxes using the eddy covariance (EC) methodology. This study was carried out on theSoutheast coast of Brazil and the adjacent open ocean during two days of the austral winte...

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...

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,...
