Consisting of smartphones tethered to solar panels, the devices — nicknamed “Guardians” — listen in on animal calls, wind, rain, and other ambient sounds and continuously transmit the audio to the cloud, where they’re analyzed by machine-learning algorithms similar to those police use to detect gunshots in urban areas.
The Amazon, the single largest tropical rainforest and home to 10% of the world’s known species, could lose half of its plants and animals by the end of the century as global warming ravages the planet—and that loss of biodiversity is just a snapshot of what’s happening to the world’s forests, wetlands, and seas.
During a late 19th-century rubber boom, Amazonia became increasingly well mapped out as the young nations of Peru, Bolivia, Brazil and Colombia vied for territorial control. The rights and interests of Amazonian peoples were never included in this process and they would be continually denied rights, recognition and citizenship from these nations until the 1980s and 1990s. Even following legal recognition, their territorial rights – critical for their continued existence – are still often ignored in practice.
The world’s tropical forests are so degraded they have become a source rather than a sink of carbon emissions, according to a new study that highlights the urgent need to protect and restore the Amazon and similar regions.
Brazil’s government has abolished a vast national reserve in the Amazon to open up the area to mining.
Humans have destroyed a tenth of Earth’s remaining wilderness in the last 25 years and there may be none left within a century if trends continue, according to an authoritative new study.
Researchers found a vast area the size of two Alaskas – 3.3m square kilometres – had been tarnished by human activities between 1993 and today, which experts said was a “shockingly bad” and “profoundly large number.”
Deforestation in the Amazon has been a growing problem over the past five decades, with ranchers leading the way in clearing rainforest for cattle and cultivation. But while Brazil, the largest country in South America, seems on track to reduce deforestation, other major Amazonian countries like Peru are increasingly struggling to protect their share of the world’s largest rainforest.
Thousands of residents in the northern Peruvian jungle are facing a water quality emergency following two pipeline ruptures that spilled crude oil into various waterways — including a tributary of the Amazon River — damaging a vast area known for its ecological value.
Peru, the host for December’s UN climate change summit, stores nearly seven billion metric tons of carbon stocks, mostly in its Amazon rainforest. That’s more than US annual carbon emissions for 2013 which were calculated at 5.38 billion tons, the new research by the Carnegie Institute for Science (CIS) shows.
