The research objective is to examine, at different scales, the processes that govern the advection and reaction of carbon in the lowest reach of the Amazon River and along the near-shore coastline of the Western Tropical Atlantic Ocean. The mainstem of the river is a large supplier of carbon dioxide (CO2) to the atmosphere, most of which is sourced as organic carbon from the surrounding l…
The expansion of intensive crop agriculture in tropical forests is a global phenomenon driven by land availability, shifts in diet to more meat consumption and growth of human populations and incomes. These land-use changes have not been accompanied by significant improvements in water governance. This will become increasingly important as changes to climate impact the amount, timing and …
The premise of this project is that C02 outgassing and respiration rates are supported by the cycling of a large variety of OM fuels - derived from allochthonous, autochthonous, and macrophytic biomass - each with an inherent lability and unique rate of degradation, varying systematically over the hydrograph. Using new methods, these processes can be tracked, quantified and understood wit…

Continental aquatic ecosystems are important contributors to the global carbon balance. The lower Amazon region alone is responsible for about 25% of global CO2 and CH4 emissions from rivers. With the justification of dedicating efforts to understand how the hydrodynamics of the final portion of the Amazon River basin influences environmental variables, this study aim evaluates the dynami…
In the last decades, a striking agribusiness expansion and intensification in Brazilian Amazon agricultural frontier is promoting a fast shift in land use and cover, associated with high deforestation rates and environmental impacts. The Alto Xingu River Basin is located in Mato Grosso, the Brazilian state with one of the highest rates of agricultural and livestock production, as well as …
The growing awareness on issues related to natural resources world wide, decision-making processes of environmental issues have received increasing attention. Ensuring that these processes are based on solid scientific information is crucial to guarantee their effectiveness in meeting environmental challenges. In this context, this project, intitule "Dynamics of land use and land cover in…
The amazon biodiversity has been impaired by historical forms of occupation and land-use that cause habitat loss and forest fragmentation. These anthropogenic disturbances associated with climate change have direct consequences on the distribution of species. Modeling capabilities with added ecological foundations have been employed as potential alternatives for acquiring knowledge about …

The southeastern Amazonia has been submitted to a rapid change in land use. There are studies indicating that combined effects of forest loss and climate change have altered the energy and water balances components in many regions of Amazon Basin. Evaluate the changes on water balance components of Amazon region is essential to understand how the anthropogenic activities and the climate c…
This proposal aims to study the dynamics of land use intensification and its interaction with socioeconomic and environmental indicators in the Alto Xingu Basin - agricultural frontier of the Brazilian Amazon. Intensification is the increase in agricultural production without the increase in cultivated area. This phenomenon is characterized by its complexity and multidimensionality due to…
The amazon rainforest has been impaired by historical forms of occupation and land-use that cause habitat loss and forest fragmentation. These anthropogenic disturbances associated with climate change have direct consequences on the distribution of species. Amazon nut (Bertholetia excelsa Bonpl.) is an endangered amazon native species and protected by Ministry of Environment of Brazil (MM…
