Coupling the terrestrial hydrology model with biogeochemistry to the integrated LAND surface model: Amazon Basin applications.

We coupled the hydrologic routing and flood dynamics model Terrestrial Hydrology Model with Biogeochemistry (THMB) to the Integrated LAND Surface Model (INLAND) and compared simulations of the discharge and flood extent area against gauge station and satellite-based information in the Amazon Basin. ...

The forest transition in São Paulo, Brazil: historical patterns and potential drivers.

Agricultural expansion has caused extensive deforestation throughout the tropics in the last decades, nevertheless, some countries have experienced native forest gains. In the 20th century, the state of São Paulo, Brazil, transitioned from an agricultural frontier to an agro-industrial state, and i...

Engagement of scientific community and transparency in C accounting: the Brazilian case for anthropogenic greenhouse gas emissions from land use, land-use change and forestry.

To effectively implement the Paris Agreement, capacity in carbon accounting must be strengthened in the developing world, and partnerships with local academic institutions can do the accounting for governments and fill the capacity gap. This paper highlights the Brazilian case, focusing on ways in w...

Topic modeling method for analyzing social actor discourses on climate change, energy and food security.

Debates on climate change, energy and food security concerns have underscored the need for new methods and tools to explore and understand the complexity of these relevant issues. In this study, we used unsupervised probabilistic modeling-latent Dirichlet allocation (LDA)-to examine the changes in s...

Sustainability and governance of sugarcane ethanol companies in Brazil: topic modeling analysis of CSR reporting.

The current debate on corporate social responsibility was triggered by the understanding that companies should be responsible for mitigating the impacts of their activities on the society and the environment. In this paper, drawing on the structural power of business, we examine the rule-setting pow...

Relationships between variability in precipitation, river levels, and beef cattle production in the Brazilian Pantanal.

The hydrology of the Brazilian Pantanal, part of the largest humid tropical area on the planet, follows the rhythm of seasonal floods. The traditional movement of cattle herds in the southern Pantanal is defined by these seasonal flooding patterns, which determine the availability and quality of nat...

Beef cattle production systems in south Pantanal: considerations on territories and integration scales.

Pantanal is one of the largest wetlands in the world. In its southern portion, it hosts significant beef cattle ranching, having a herd of 4,832,200 head of cattle in 2016 (IBGE, 2018). Yet it presents intra-regional differences and complementarities. This article discusses such current territory de...

21st Century drought-related fires counteract the decline of Amazon deforestation carbon emissions. Nature Communications, v.9, n.1, e536, 2018.

Tropical carbon emissions are largely derived from direct forest clearing processes. Yet, emissions from drought-induced forest fires are, usually, not included in national-level carbon emission inventories. Here we examine Brazilian Amazon drought impacts on fire incidence and associated forest fir...

Measuring resilience and assessing vulnerability of terrestrial ecosystems to climate change in South America.

Climate change has been identified as the primary threat to the integrity and functioning of ecosystems in this century, although there is still much uncertainty about its effects and the degree of vulnerability for different ecosystems to this threat. Here we propose a new methodological approach c...

Airborne laser scanning for terrain modeling in the Amazon forest.

Very few studies have been devoted to understanding the digital terrain model (DTM) creation for Amazon forests. DTM has a special and important role when airborne laser scanning is used to estimate vegetation biomass. We examined the influence of pulse density, spatial resolution, filter algorithms...
