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...

Implementing Brazil’s Forest Code: a vital contribution to securing forests and conserving biodiversity.

Meeting Brazil's ambitious national commitments on both climate change mitigation and biodiversity conservation depends on securing its reserves of forest carbon and biodiversity. Brazil's 'Forest Code' is a key tool to reconcile environmental preservation and agricultural production; it limits defo...

Segurança hídrica da bacia do Rio Paraíba do Sul

A intensificação de extremos climáticos, o aumento da demanda, e a falta de um planejamento integrado dos recursos hídricos no Brasil vêm se tornando mais evidente ano após ano. No ano de 2014, deparamo-nos com cheias nas regiões Norte e Sul, enquanto o Sudeste e Nordeste sofrem com deficiên...

Mind the gap: New insights on large-scale forest dynamics over Amazonian forests from airborne lidar and canopy gap data.

Tree mortality has been pointed out as a key factor to quantify global forests carbon stocks and turnover. While there have been recent developments on observational studies aiming at detection and attribution of tree mortality using remote sensing data in temperate forests, the spatial and temporal...

Assessment of land use and land cover datasets for Brazil and impact on C emissions.

Brazil is responsible for about one third of the global land use and land cover change (LULCC) carbon dioxide emissions. However, there is a disagreement among different methodologies on the magnitude and trends in emissions and their geographic distribution. One of the main uncertainties is associa...

Isotopic composition of precipitation in a southeastern region of Brazil during the action of the south Atlantic convergence zone.

The use of stable isotopes of hydrogen and oxygen is a tool widely used to trace water paths along the hydrological cycle, providing support for understanding climatic conditions in different spatial scales. One of the main synoptic scale events acting in southeastern Brazil is the South Atlantic Co...

Evapotranspiration in the Amazon: spatial patterns, seasonality, and recent trends in observations, reanalysis, and climate models.

Water recycled through transpiring forests influences the spatial distribution of precipitation in the Amazon and has been shown to play a role in the initiation of the wet season. However, due to the challenges and costs associated with measuring evapotranspiration (ET) directly and high uncertaint...
