This pair of images reveals how dramatically and rapidly the Amazon can be transformed. The images compare deforested areas (tan) to forest (green) in 2000 (top) versus 2006 (bottom). The area, which is in southern Rondônia southwest of the Pacaás Novos National Park, was almost completely cleared during the period. The decreased greenness of the remaining forest in 2006 may be from a variety of causes: drought, degradation from logging or accidental fire, or different angles of observation during the two satellite overpasses.

Acquired May 27, 2003, this true-color Landsat ETM image shows part of a plantation in Malaysian Borneo, along the edge of the forest. The area outlined in white in the ETM image appears in greater detail in the image acquired on June 18, 2002, by the commercial satellite Ikonos. The images show the differences between forest, cleared land, and palm plantation.

In June 2008, an international team of researchers released a report on the state of Papua New Guinea’s forests. The study summarized the findings from a five-year project in which the scientists compared high-resolution satellite imagery from the early 1970s and the early 2000s. The researchers found evidence of rapid deforestation and degradation, driven primarily by logging, subsistence agriculture, fires, and the development of mines and plantations.
