Thousands of square kilometers of the world’s second-largest rainforest, the Congo Basin, sit on the verge of destruction, according to a new report released today by Earthsight, the London-based non-profit…
Study: 142 existing and under construction Andean dams are fragmenting the Amazon, putting ecosystems at risk and impacting up to 30 million people. Another 160 dams are planned.
Forest fires are no longer driven mainly by deforestation in the Brazilian Amazon, with climate change induced drought now taking a major role.
A new study finds that putting a price on carbon could drastically reduce the amount of deforestation in the tropics by 2050: $20 per metric ton (about $18/short ton) could…
When a farmer cuts down a tree in the Democratic Republic of Congo, there’s often a reason for it. She’s most likely clearing the land to plant crops — the…
It’s become a trend for big corporations to pledge that their products won’t cause any more deforestation. And while many experts believe in the potential of these “zero-deforestation” commitments to…
Imagine you needed to map the spread of an invasive plant species in a tropical forest. Hyperspectral imaging and LiDAR are great at identifying vegetation, but have their limitations and…
The Brazilian Amazon lost 184 km2 of forest in December 2017, according to the country’s Institute of Man and the Environment of the Amazon (Imazon). The data, obtained exclusively by…
Experts say 2017 Brazilian wildfires were caused not principally by drought, but mostly set by people, and worsened by human-caused forest degradation. Agency budget cuts worsened the crisis.
Pres. Trump’s 2018 budget would kill new satellites vital to climate research and weather forecasting, hobbling international science. A congressional budget vote may come next week.
Technology above the clouds is helping scientists study sharks beneath the waves. A new initiative combines shark movement data with publicly available vessel identification data—both transmitted to researchers via satellite—to…
A satellite-based alert system can now detect fine-scale deforestation in near-real time, enabling managers or rangers in tropical forests to respond to early stages of deforestation. Anyone can now register…
Carbon-rich tropical forests, which are often among the least-disturbed habitats, seem to be ideal bastions for sensitive and threatened animals, particularly compared to lower-carbon areas like timber and oil palm…
A new study found that mining caused nearly 10 percent of deforestation in the Brazilian Amazon between 2005 and 2015, not the 1-2 percent assumed by past assessments.
A recent study mapped the world’s dry forests using a relatively new tool that combines creative satellite image analysis with local- and national-scale knowledge. Natural resource agencies worldwide inventory their…
During the wet season, manatees swim Amazon basin floodplains; in dry times they migrate to lakes. Hundreds of planned dams could disrupt that cycle.
Summer sea ice didn’t reach its lowest extent on record in 2017, but that’s not the only measurement that matters, experts warn.
Study warns that six hydroelectric mega-dams proposed for Andean highlands would put environment and food security at risk in Amazon basin.
Tool helps communities, researchers, policymakers, activists assess a proposed dam’s economic viability, greenhouse gas emissions and more.
