How can diverse national food and land-use priorities be reconciled with global sustainability targets? Lessons from the FABLE initiative.
There is an urgent need for countries to transition their national food and land-use systems toward food and nutritional security, climate stability, and environmental integrity. How can countries satisfy their demands while jointly delivering the required transformative change to achieve global sus...

A comparison of global mangrove maps: assessing spatial and bioclimatic discrepancies at poleward range limits.
Mangrove distribution maps are used for a variety of applications, ranging from estimates of mangrove extent, defor-estation rates, quantify carbon stocks, to modelling response to climate change. There are multiple mangrove distribu-tion datasets, which were derived from different remote sensing da...

Mapping tropical forest cover and deforestation with planet NICFI satellite images and deep learning in Mato Grosso State (Brazil) from 2015 to 2021.
Monitoring changes in tree cover for assessment of deforestation is a premise for policies to reduce carbon emission in the tropics. Here, a U-net deep learning model was used to map monthly tropical tree cover in the Brazilian state of Mato Grosso between 2015 and 2021 using 5 m spatial resolution ...

Spatial–temporal analysis of a summer heat wave associated with downslope flows in southern Brazil: implications in the atmospheric boundary layer.
This study investigates a summer heat wave (HW) associated with downslope winds (DWs) affecting the central region of the state of Rio Grande do Sul (RS), Brazil. The temporal evolution of both phenomena is analyzed in the atmospheric boundary layer (ABL) using a combination of micrometeorological a...

Diverse anthropogenic disturbances shift Amazon forests along a structural spectrum.
Amazon forests are being degraded by myriad anthropogenic disturbances, altering ecosystem and climate function. We analyzed the effects of a range of land-use and climate-change disturbances on fine-scale canopy structure using a large database of profiling canopy lidar collected from disturbed and...

What comes after crises? Key elements and insights into feedback amplifying community self-organization.
In face of complex socio-environmental issues experienced in different social-ecological systems, we ask if comprehensive lessons could be learned from cases of community self-organization that were successful in solving collective problems at the local level. Considering that the trajectory of each...

The drivers and impacts of Amazon forest degradation.
Approximately 2.5 × 106 square kilometers of the Amazon forest are currently degraded by fire, edge effects, timber extraction, and/or extreme drought, representing 38% of all remaining forests in the region. Carbon emissions from this degradation total up to 0.2 petagrams of carbon per year (Pg C ...

Evaluation of surface data simulation performance with the Brazilian Global Atmospheric Model (BAM).
In this study, we evaluated the performance of the Brazilian Global Atmospheric Model (BAM), in its version 2.2.1, in the representation of the surface variables solar radiation, temperature (maximum, minimum, and average), and wind speed. Three experiments were carried out for the period from 2016 ...
