Peru’s deforestation rates surged in 2005, according to new analysis published in the journal Science.

Using high resolution satellite data from the Peruvian Amazon, a team led by Stanford University scientists found a marked increase in forest disturbance and clearance for the 2004-2005 year. Forest degradation for the year — including 1,174 square kilometers of forest cleared and 1,070 disturbed — was about 175 percent of the mean for the six-year period examined.
The researchers say that new logging concessions appear to have been a factor in the increase in forest disturbance between 2003 and 2005. Higher commodity prices for agricultural products may have also played a part.
The research nonetheless revealed some positive results.
“Overall, only 2% of the forest disturbances and 1% the deforestation detected in the entire study area occurred within the boundaries of natural protected areas. Furthermore, territories occupied by indigenous communities contained 11% and 9% of the total forest disturbance and deforestation, respectively,” wrote the authors. “These results clearly show that these two forms of land-use allocation can provide effective protection against forest damage.”
Peru has some 661,000 square kilometers of tropical forests—an area a little larger than France—and one of the lowest annual deforestation rates in the Amazon basin.
