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...

CO2 physiological effect can cause rainfall decrease as strong as large-scale deforestation in the Amazon.
The climate in the Amazon region is particularly sensitive to surface processes and properties such as heat fluxes and vegetation coverage. Rainfall is a key expression of the land surface atmosphere interactions in the region due to its strong dependence on forest transpiration. While a large numbe...

Disaster risk areas in Brazil: outcomes from an intra-urban scale analysis.
This study investigates the main threats related to environmental degradation that affect Amazonian Indigenous Lands (ILs). Through a cluster analysis, we group ILs according to the set of common environmental threats that occur within and outside their limits. The results show that most of the 383 ...

Understanding water and energy fluxes in the Amazonia: Lessons from an observation-model intercomparison.
Tropical forests are an important part of global water and energy cycles, but the mechanisms that drive seasonality of their land-atmosphere exchanges have proven challenging to capture in models. Here, we (1) report the seasonality of fluxes of latent heat (LE), sensible heat (H), and outgoing shor...

Nutrient Balance and Use Efficiency in Agricultural Lands in the Vermelho River Watershed, Upper Pantanal, Brazil.
Agricultural systems play a key role in achieving many of the Sustainable Development Goals, established by the United Nations, given the current challenge of producing enough food to feed a global population that is expected to reach 10 billion people by 2050. More efficient and sustainable use of ...
