When the whole is less than the sum of all parts – Tracking global-level impacts of national sustainability initiatives.
The United Nations Sustainable Development Goals (SDGs) are described as integrated and indivisible, where sustainability challenges must be addressed across sectors and scales to achieve global-level sustainability. However, SDG monitoring mostly focuses on tracking progress at national-levels, for...

Hybrid power generation for increasing water and energy securities during drought: Exploring local and regional effects in a semi-arid basin.
Reservoirs of hydropower plants (HPP) can amend water, energy, and food security in semi-arid regions. However, during severe droughts, the priority of energy demand leads to critical conditions of water availability. To reduce water use for energy, one possible measure is the adoption of solar powe...

Obtaining the daily actual evapotranspiration through remote sensing techniques application in Brazilian Semiarid.
Large volumes of water are released to the atmosphere through evaporation from soil and transpiration from vegetation, constituting evapotranspiration (ET). Estimating the water consumption in vegetated areas is important for the management and rational use of this resource. For this study were proc...

Assessment of CMIP6 Performance and Projected Temperature and Precipitation Changes Over South America.
We evaluate the performance of a large ensemble of Global Climate Models (GCMs) from the Coupled Model Intercomparison Project Phase 6 (CMIP6) over South America for a recent past reference period and examine their projections of twenty-first century precipitation and temperature changes. The future...

Phytoplankton community in a tropical estuarine gradient after an exceptional harmful bloom of Akashiwo sanguinea (Dinophyceae) in the Todos os Santos Bay.
The objective of this study was to evaluate variations in the composition and abundance of the phytoplankton community after an exceptional harmful bloom of Akashiwo sanguinea that occurred in Todos os Santos Bay (BTS) in early March, 2007. Samples were collected every ten days, between April, 2007 ...

Satellite Image Time Series Analysis for Big Earth Observation Data.
The development of analytical software for big Earth observation data faces several challenges. Designers need to balance between conflicting factors. Solutions that are efficient for specific hardware architectures can not be used in other environments. Packages that work on generic hardware and op...

Too Fine to be Good? Issues of Granularity, Uniformity and Error in Spatial Crime Analysis.
Objectives: Crime counts are sensitive to granularity choice. There is an increasing interest in analyzing crime at very fine granularities, such as street segments, with one of the reasons being that coarse granularities mask hot spots of crime. However, if granularities are too fine, counts may be...

Improving victimization risk estimation: A geographically weighted regression approach.
Standardized crime rates (e.g., homicides per 100,000 people) are commonly used in crime analysis as indicators of victimization risk but are prone to several issues that can lead to bias and error. In this study, a more robust approach (GWRisk) is proposed for tackling the problem of estimating vic...

Determining ecosystem functioning in Brazilian biomes through foliar carbon and nitrogen concentrations and stable isotope ratios.
By analyzing 6,480 tree leaf samples from 57 sites within Brazilian biomes, we considered whether vegetation types in terrestrial ecosystems reflect biogeochemical diversity and whether they fit into a leaf economics spectrum (LES). To achieve this, we investigated the relations among leaf carbon (C...

The role of ENSO flavours and TNA on recent droughts over Amazon forests and the Northeast Brazil region.
Amazon tropical forests and the semiarid Northeast Brazil (NEB) region have registered very severe droughts during the last two decades, with a frequency that may have exceeded natural climate variability. Severe droughts impact the physiological response of Amazon forests, decreasing the availabili...

Nitrogen emissions in Latin America: A conceptual framework of drivers, impacts, and policy responses.
Reactive nitrogen has both positive and negative effects on environment and human health. The use of nitrogen fertilization enabled raising crops and livestock to feed an increasing world population, but at the same time resulted in a succession of unwanted impacts occurring through air, soil, and w...
