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.
