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...

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...

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...
