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,...

Probabilistic flood forecasting in the Doce Basin in Brazil: effects of the basin scale and orientation and the spatial distribution of rainfall.

We critically examined the performance of probabilistic streamflow forecasting inthe prediction of flood events in 19 subbasins of the Doce River in Brazil using theEta (4 members, 5 km spatial resolution) and European Centre for Medium-RangeWeather Forecasts (ECMWF; 51 members, 32 km resolution) we...

Using a hydrologic model to assess the performance of regional climate models in a semi-arid Watershed in Brazil.

This study assessed the impact of climate change on the hydrological regime of the Paraguaçu river basin, northeastern Brazil. Hydrological impact simulations were conducted using the Soil and Water Assessment Tool (SWAT) for 20202040. Precipitation and surface air temperature projections from two ...

Neotectonics and tree mortality in a forest ecosystem of the Negro basin: geomorphic evidence of contemporary seismicity in the intracratonic Brazilian Amazonia.

Neotectonic activity was increasingly recorded over the Amazonian lowlands, even during historical times of a few tens of centuries. However, detailed analyses linking structures and styles of deformation are still few considering the large dimension of the region. Such events in a relatively recent...
