Rising Gold Prices Mean Deforestation in Peruvian Amazon Up 600%

One side effect of gold prices continuing to rise (now at a new record of $1500/ounce): Deforestation in parts of the Peruvian Amazon have increased up to 600% since 2003. That's according to a new study in PLoS ONE, which shows how unregulated mining in Peru, done by small-scale miners just trying to support their families has caused approximately 15,200 acres of previously pristine forest to be cleared between 2003-2009, with a marked uptick since 2006.

Though such small-scale mining has taken place in the region for generations recent gold price rises has clearly increased the pace of gold mining and environmental degradation.

Report co-author Jennifer Swenson says that the mining is "now plainly visible from space" and that deforestation caused by mining has "largely outpaced nearby deforestation caused by human settlement" since 2006.

Beyond the deforestation, mercury is used to process the ore, which contaminates the water and soil as well as puts the health of miners and their families into jeopardy.

Swenson notes, "Virtually all mercury imported into Peru is used for artisanal gold mining and imports have risen exponentially since 2003, mirroring the rise in gold prices."
