Even in Colombia, where President Iván Duque has attempted to rein in illegal logging, a recent increase in forest fires led more than 150 international academics and activists last week to send a letter urging the government to take a more aggressive stance. Indeed, local prosecutors and police...
distributed in all vegetation categories in the region. The map uses airborne laser scanning (ALS) data calibrated by field forest inventories that are extrapolated to the region using a machine learning approach with inputs from Synthetic Aperture Radar (PALSAR), vegetation indices obtained from the...
The resultant forest degradation map showed good agreement (86% overall accuracy) with areas of degraded forest visually interpreted from two IKONOS images. In addition, high correlation ( R 2=0.97) was observed between the total live aboveground biomass of degraded forest classes (defined at the ...
Wildfires continue to rage in Brazil’s Amazon rainforest. Our live coverage has ended. Here’s what you need to know about the fires in Brazil: The Amazon is currently facing record-breaking wildfires: Brazil’s space research center (INPE) said this week that the number of fires in ...
The map, like the data, has been taken from TerraBrasilis [28]. It can be observed that in the south and east of the Amazon rainforest there is a higher degree of deforestation; this is in accordance with the number of municipalities in the region. Thus, it can be concluded that, ...
Brazil’s Amazon rainforest is in flames, burning at the highest rate since 2013, when that nation’s space research center first began tracking fires there. Here’s what we know. How big is the Amazon rainforest and what does it matter? The world’s largest rainforest, the Amazon ...
The Amazon rain forest is one of the most diverse places on Earth, home to unknown thousands of species, including thousands of trees. Until now, scientists didn't know which trees dominated the forest and where different tree species were located. A new study published in the Oct. 17, 201...
and soils. Here we show for the first time that an intact forest canopy near artisanal gold mining intercepts large amounts of particulate and gaseous mercury, at a rate proportional with total leaf area. We document substantial mercury accumulation in soils, biomass, and resident songbirds in so...
