Evaluating spatial coverage of data on the aboveground biomass in undisturbed forests in the Brazilian Amazon.

Background: Brazilian Amazon forests contain a large stock of carbon that could be released into the atmosphere as a result of land use and cover change. To quantify the carbon stocks, Brazil has forest inventory plots from diferent sources, but they are unstandardized and not always available to th...

Solar smart grid as a path to economic inclusion and adaptation to climate change in the Brazilian Semiarid Northeast.

Purpose: This study aims to exploit the abundance of solar energy resources for socioeconomic development in the semi -arid Northeastern Brazil as a potent adaptation tool to global climate change. It points out a set of conjuncture factors that allow us to foresee a new paradigm of sustainable deve...

The seasonal variability and trends for the surface solar irradiation in northeastern region of Brazil.

Earlier studies have demonstrated that the Northeastern Brazilian region (NEB) has the most abundant solar energy resource of the Brazilian territory due to its geographical location, and its environmental characteristics. However, the spatial and seasonal variability was little evaluated. This work...

Multi-scale approach to estimating aboveground biomass in the Brazilian Amazon using Landsat and LiDAR data.

Forest degradation from either natural or anthropogenic drivers involves processes that change the capacity of the ecosystem to provide services. In Brazil, estimates of carbon emissions do not currently take into account emissions from forest degradation caused by fire or by selective logging. Here...

Effects of climate and land‐use change scenarios on fire probability during the 21st century in the Brazilian Amazon.

The joint and relative effects of future land-use and climate change on fire occurrence in the Amazon, as well its seasonal variation, are still poorly understood, despite its recognized importance. Using the maximum entropy method (MaxEnt), we combined regional land-use projections and climatic dat...

Amazon forest response to CO2 fertilization dependent on plant phosphorus acquisition.

Global terrestrial models currently predict that the Amazon rainforest will continue to act as a carbon sink in the future, primarily owing to the rising atmospheric carbon dioxide (CO 2 ) concentration. Soil phosphorus impoverishment in parts of the Amazon basin largely controls its functioning, bu...

Combining LiDAR and hyperspectral data for aboveground biomass modeling in the Brazilian Amazon using different regression algorithms

Accurate estimates of aboveground biomass (AGB) in tropical forests are critical for supporting strategies of ecosystem functioning conservation and climate change mitigation. However, such estimates at regional and local scales are still highly uncertain. Airborne Light Detection And Ranging (LiDAR...

Expanding the soy moratorium to Brazil’s Cerrado

The Cerrado biome in Brazil is a tropical savanna and an important global biodiversity hot spot. Today, only a fraction of its original area remains undisturbed, and this habitat is at risk of conversion to agriculture, especially to soybeans. Here, we present the first quantitative analysis of expa...

Hydraulic traits explain differential responses of Amazonianforests to the 2015 El Niño-induced drought

Reducing uncertainties in the response of tropical forests to global change requires understanding how intra- and interannual climatic variability selects for different species, community functional composition and ecosystem functioning, so that the response to climatic events of differing frequency...

Evaluation of an ensemble of regional climate model simulations over South America driven by the ERA-Interim reanalysis: model performance and uncertainties

The capability of a set of 7 coordinated regional climate model simulations performed in the framework of the CLARIS-LPB Project in reproducing the mean climate conditions over the South American continent has been evaluated. The model simulations were forced by the ERA-Interim reanalysis dataset fo...
