Levers and leverage points for pathways to sustainability.
Humanity is on a deeply unsustainable trajectory. We are exceeding planetary boundaries and unlikely to meet many international sustainable development goals and global environmental targets. Until recently, there was no broadly accepted framework of interventions that could ignite the transformatio...

Land degradation mapping in the MATOPIBA region (Brazil) using remote sensing data and decision-tree analysis.
The expansion of agricultural activities in Brazil resulted in a loss of approximately 50% of the native vegetation of the Cerrado biome, mainly to the north of the biome in a region known as MATOPIBA. Besides contributing to accelerate climate change, the removal of native vegetation is associated ...

A multi-data assessment of land use and land cover emissions from Brazil during 2000-2019
Brazil is currently the largest contributor of land use and land cover change (LULCC) carbon dioxide net emissions worldwide, representing 17%-29% of the global total. There is, however, a lack of agreement among different methodologies on the magnitude and trends in LULCC emissions and their geogra...

Amazonia as a carbon source linked to deforestation and climate change.
Amazonia hosts the Earth's largest tropical forests and has been shown to be an important carbon sink over recent decades(1-3). This carbon sink seems to be in decline, however, as a result of factors such as deforestation and climate change(1-3). Here we investigate Amazonia's carbon budget and the...

. Non-structural carbohydrates mediate seasonal water stress across Amazon forests.
Non-structural carbohydrates (NSC) are major substrates for plant metabolism and have been implicated in mediating drought-induced tree mortality. Despite their significance, NSC dynamics in tropical forests remain little studied. We present leaf and branch NSC data for 82 Amazon canopy tree species...

Advancing a toolkit of diverse futures approaches for global environmental assessments
Global Environmental Assessments (GEAs) are in a unique position to influence environmental decision-making in the context of sustainability challenges. To do this effectively, however, new methods are needed to respond to the needs of decision-makers for a more integrated, contextualized and goal-s...

Is domestic agricultural production sufficient to meet national food nutrient needs in Brazil?
Reducing the impacts of agriculture on the environment is one of the greatest challenges of this century. In Brazil, it is often argued that more land use change is needed to achieve food security. However, analyses seeking to understand the dynamics between agricultural production for exports and f...

Case Studies on Concentric Gravity Waves Source using Lightning Flash Rate, Brightness Temperature and Backward Ray Tracing at São Martinho da Serra (29.44°S, 53.82°W).
We relate the spatial and temporal distribution of lightning flash rates and cloud top brightness temperature (CTBT) to concentric atmospheric gravity wave (CGW) events observed at the Southern Space Observatory (SSO) in São Martinho da Serra (29.44°S, 53.82°W, 488.7m) in southern Brazil. The ...

Extreme Rainfall and Hydro-Geo-Meteorological Disaster Risk in 1.5, 2.0, and 4.0°C Global Warming Scenarios: An Analysis for Brazil.
With the inclusion of demographic characteristics of the population living in vulnerable areas, a combination of empirical and climate models was used to project changes to climate and in hydro-geo-meteorological disasters in Brazil. This study investigated the effect of extreme rainfall changes and...

Smoldering characteristics of high bulk density peat.
Low-density peats from many countries have long been studied by many authors. They are mostly forest and moss peats. Different peat types, from different locations in the world, may present degradation behavior that differs significantly. Bulk density, which is one the most important physical parame...
