Demand for gold pushing deforestation in Peruvian Amazon Jeremy Hance mongabay.com April 19, 2011
Using satellite imagery from NASA, researchers were able to follow rising deforestation due to artisanal gold mining in Peru. According the study, published in PLoS ONE, Two large mining sites saw the loss of 7,000 hectares of forest (15,200 acres)—an area larger than Bermuda—between 2003 and 2009. "We present recent evidence of the global demand for a single commodity and the ecosystem destruction resulting from commodity extraction, recorded by satellites for one of the most biodiverse areas of the world," the researchers write.
Swenson and her colleagues clearly link the rise in unregulated mining to rising gold prices. "Over the last decade, the price of gold has increased 360% with a constant rate of increase of [around] 18% per year. The price continues to set new records, rising to over $1400/oz at the time of this article's publication. As a response, nonindustrial informal gold mining has risen in developing countries along with grave environmental and health consequences," the authors write. Beyond forest loss, the mining also impacts wildlife and people in the region due to mercury pollution. Miners use mercury to amalgamate with the metal, but unregulated the dangerous toxin also poison the ecosystem. According to Peru's Environment Minister fish in the area have mercury levels that are three times higher than the amount approved by the World Health Organization. These toxins make their way up the food chain. People dependent on fish, game animals, and river water in the region are likely to be impacted as well. The miners, who are often poor, uneducated, and marginalized, are most at risk given their direct handling of mercury. After fossil fuel burning, small-scale gold mining is the world's second largest source of mercury pollution contributing around 1/3 of the world's mercury pollution. The illegal gold trade also produces numerous social problems, according to the BBC, including drug trafficking, indentured labor, and child prostitution. Recently, Peru has begun a campaign to stamp out these illegal mines. In February, Around a thousand Peruvian soldiers and police officers destroyed seven and seized thirteen boats used by illegal gold miners in the region. The operation aims to destroy 300 pieces of illegal mining. But given the high price for gold its questionable whether this will work in the long-term. Swenson says Peru should also think outside the box and consider limiting the importation of mercury. "Virtually all mercury imported to Peru is used for artisanal gold mining and imports have risen exponentially since 2003, mirroring the rise in gold prices," she says. "Given the rate of recent increases, we project mercury imports will more than double by the end of 2011, to about 500 tons a year." CITATION: Jennifer J. Swenson, Catherine E.

(03/03/2011) A new report has uncovered 90 oil spills by Pluspetrol in northern Peru's Amazon rainforest over the past 3 years. Covering two oil blocs—1-AB and 8—the report, complied by the Federation of Indigenous Communities of the Corrientes River (FECONACO), recorded 18 major oil spills in just the last year. "A week after the landmark ruling against Chevron in Ecuador for $9 billion of
damage from operations in the 1970's and 80's, this new report highlights
the ongoing devastation caused by the oil industry on the fragile Amazon
ecosystem and the people that live there," said Atossa Soltani, Executive
Director at Amazon Watch, in a press release.
(09/06/2010) Scientists using a combination of satellite imagery, airborne-laser technology, and ground-based plot surveys to create three-dimensional high resolution carbon maps of the Amazon rainforest have documented a surge in emissions from deforestation and selective logging following the paving of the Trans-Oceanic Highway in Peru. The study, published this week in the early edition of the Proceedings of the National Academy of Sciences, reveals that selective logging and other forms of forest degradation in Peru account for nearly a third of emissions compared to deforestation alone.
