Space Agencies and Google To Monitor Deforestation From Satellites

Space agencies from Europe, the U.S., and several other nations are joining forces with Google Earth and a conservation organization to annually monitor deforestation rates around the globe using satellite imagery. The Group on Earth Observations (GEO), a global partnership of 80 governments and more than 50 organizations, is launching pilot projects in Australia, Brazil, Cameroon, Guyana, Indonesia, Mexico, and Tanzania to inventory forests and track rates of deforestation. Such annual monitoring — which until recently has been carried out every five years — will be instrumental in helping support programs in which governments, conservation groups, and investors pay to preserve tropical forests, GEO officials said. An international mechanism for preserving forests using carbon credits is expected to be approved at the Copenhagen climate conference in December. “The only way to measure forests efficiently is from space,” said Jose Achache, director of GEO. “Investors will want some sort of guarantee that… forests will remain there and remain in good condition.” Google Earth, which already is involved in using satellite technology to monitor deforestation, will participate in the GEO effort, Achache said.
