Years of deforestation in Peru are visible from space, tracked in a new animation created from NASA satellite views. And the forest loss is escalating at an alarming rate.
The image series was captured by satellites Landsat 7 and Landsat 8 from 2013 to 2018. Shared on April 19 by NASA Earth Observatory, the animated sequence reveals devastating depletion in the forests of southeastern Peru's Madre de Dios region, covering approximately 1,350 square miles (3,500 square kilometers).
Andrea Nicolau, a graduate research assistant at the University of Alabama in Huntsville, mapped forest loss in the images using a technique known as spectral mixture analysis, which differentiates between types of land cover based on light properties in every pixel, according to NASA. Using this method, Nicolau determined that about 79 square miles (206 square km) of forest disappeared during the five-year period, and the greatest loss took place between 2017 and 2018.

The hardest-hit areas were found in buffer zones close to protected areas. Illegal gold mining is responsible for much of the deforestation on lands belonging to the indigenous Peruvian tribe known as Kotsimba Native Community. Indeed, those involved with mining operations and other activities that threaten Peruvian forests now have easier access to remote locations following the recent completion of Peru's Interoceanic Highway, NASA reported.
