Modelo de análise para os impactos cumulativos de pequenas centrais hidrelétricas em cascata.
Há importantes lacunas metodológicas para se analisar devidamente os impactos cumulativos de um conjunto de empreendimentos, considerando as complexidades e interações entre os impactos. Esse é o caso de aproveitamentos hidrelétricos, os quais afetam funções ecossistêmicas de forma signific...- por Portal Padrão

Collaborative methodological approaches towards Water-Energy-Food Nexus.
The Food-Water-Energy (FWE) nexus represents, above all, a perspective, a way of looking at the world, the problems, the solutions, providing a view of the three main resource systems of food, water and energy, not in isolation, but as a system, with many and diverse cross-links between the subsyste...- por Portal Padrão

Tropical ecosystem greenhouse gas accounting.
In this chapter, we examine the main components of greenhouse gas budgets from tropical terrestrial and aquatic environments, including how these components are measured and modeled at scales ranging from field plots to regions. We discuss uncertainties associated with measurements and models, revie...- por Portal Padrão

Efeito do uso e cobertura da terra na dinâmica do carbono e nitrogênio em turfeiras na várzea do rio Paraíba do Sul
As turfeiras armazenam grande quantidade de carbono (C) e têm atuado como sumidouros de CO2 atmosférico, mas também podem se comportar como importantes fontes de Gases de Efeito Estufa (GEE) para a atmosfera (CO2, CH4 e N2O) quando submetidas a drenagem e mudança no seu uso alterando a cobertura...- por Portal Padrão

Compound drought–heat extremes in the Pantanal region during 2019–21: causes and environmental impacts
The Pantanal region in South America is one of the worlds largest wetlands. Since 2019, the Pantanal has suffered a prolonged drought that has spelled disaster for the region, and subsequent fires have engulfed hundreds of thousands of hectares, and this situation has worsened in 2021. The lack of r...- por Portal Padrão

Validation of the Brazilian Global Atmospheric Model with the inclusion of aerosols.
The Suns radiation is the primary energy source for chemical, biological, and physical processes that happen in the climate system. Thus, the earth-atmosphere radiative balance system is one of the main aspects of climate change. Natural fluctuations in incident solar radiation caused by the sunspot...- por Portal Padrão

Impacts of land use and land cover changes on hydrological processes and sediment yield determined using the SWAT model.
Land use and land cover (LULC) changes strongly affect local hydrology and sediment yields. The current study focused on a basin in the Brazilian Amazon and had the following three objectives: (1) to perform an effective diagnosis of flow and sediment yield, (2) to evaluate the impacts of LULC chang...- por Portal Padrão

Characteristics of lightning-caused wildfires in central Brazil in relation to cloud-ground and dry lightning
Lightning ignition is the major cause of natural wildfires in several regions worldwide. Determining if wildfires in remote uncontrolled areas result from natural lightning as opposed to anthropic action is a relevant and yet-unsolved challenge for large regions of the planet, with scientific and ma...- por Portal Padrão

Environmental vulnerability assessment of Brazilian Amazon Indigenous lands.
Amazonian Indigenous Lands (ILs) are human-environment systems facing a multitude of environmental threats. Yet, the resulting vulnerability of these systems are to date unknown. We adopt the theoretical vulnerability framework of the IPCC to assess the environmental vulnerability of Brazilian Amazo...- por Portal Padrão
