Feedback between drought and deforestation in the Amazon.
Deforestation and drought are among the greatest environmental pressures on the Amazon rainforest, possibly destabilizing the forest-climate system. Deforestation in the Amazon reduces rainfall regionally, while this deforestation itself has been reported to be facilitated by droughts. Here we quant...

Comparison of cloud cover detection algorithms on sentinel-2 images of the Amazon tropical forest.
Tropical forests regulate the global water and carbon cycles and also host most of the worlds biodiversity. Despite their importance, they are hard to survey due to their location, extent, and particularly, their cloud coverage. Clouds hinder the spatial and radiometric correction of satellite image...

A climate-change vulnerability and adaptation assessment for Brazil’s protected areas.
Brazil hosts the largest expanse of tropical ecosystems within protected areas (PAs), which shelter biodiversity and support traditional human populations. We assessed the vulnerability to climate change of 993 terrestrial and coastal-marine Brazilian PAs by combining indicators of climatic-change h...

Mapping Atlantic rainforest degradation and regeneration history with indicator species using convolutional network.
The Atlantic rainforest of Brazil is one of the global terrestrial hotspots of biodiversity. Despite having undergone large scale deforestation, forest cover has shown signs of increases in the last decades. Here, to understand the degradation and regeneration history of Atlantic rainforest remnants...

Seasonal changes of the South American monsoon system during the Mid‑Holocene in the CMIP5 simulations.
The South American Monsoon System (SAMS) is a major climatic feature of South America, and its domain extends from Amazon to La Plata basin. The SAMS region is vulnerable to variations of climate and precipitation patterns, which could impact economic activities and lead to potential societal conseq...

Biodiversity-mediated effects on ecosystem functioning depend on the type and intensity of environmental disturbances.
Environmental disturbances affect ecosystem functioning through changes in organisms' metabolism (direct effect) and biodiversity loss (indirect or biodiversity-mediated effect). It is still a challenge to separate direct and biodiversity-mediated effects of environmental changes on ecosystem functi...

Land-water-food nexus of biofuels: discourse and policy debates in Brazil.
Concerns regarding water scarcity, food security, and land/soil degradation are increasing, and these issues are far from being independent of bioenergy production. The competing need for land and water resources in food and bioenergy production have been at the forefront of policy debates. In this ...

Diversity of cattle raising systems and its effects over forest regrowth in a core region of cattle production in the Brazilian Amazon.
Roughly 60% of all deforested lands in the Brazilian Amazon are covered with pastures, putting cattle raising in evidence as a major driver of deforestation and also of forests' regrowth. Still, the role of cattle raising diversity in the landscape dynamics of this region remains poorly understood. ...

Erosion of the nocturnal boundary layer in the central Amazon during the dry season.
In this study, the erosion of the nocturnal boundary layer (NBL) was analyzed in the central Amazon during the dry season of 2014, using data from the GoAmazon 2014/5 Project and high-resolution model outputs (PArallelized Les Model PALM). The dataset consisted of in situ (radiosonde) and remote sen...

Assessing different flood risk and damage approaches: a case of study in progreso, Yucatan, Mexico.
This study applies three different methods to assess the flood risk and damage from the strongest high-pressure cold front (locally known as 'Norte') event in terms of the residual tide from 30 years (1979-2008) of data for Progreso, Yucatan. The most important difference between the three methods i...
