This includes an understanding of the extent of forest area, information about what the forest contains and how the forest resource is managed. Forest monitoring provides this information.
Brazil confirms rising deforestation in the Amazon
(03/14/2015) The Brazilian government has officially confirmed that deforestation in the Amazon is pacing sharply higher than a year ago. Figures released last week by the National Institute for Space Research (INPE) shows that forest clearing detected by DETER — a short term deforestation monitoring system based on coarse satellite imagery — is 63 percent higher for the twelve months ended January 31, 2015 relative to the year earlier period.
Rainforest loss increased in the 2000s, concludes new analysis
(02/25/2015) Loss of tropical forests accelerated roughly 60 percent during the 2000s, argues a paper published in the journal Geophysical Research Letters. The findings contradict previous research suggesting that deforestation slowed since the 1990s. The study is based on a map of 1990 forest cover developed last year by Do-Hyung Kim and colleagues from the University of Maryland. The map, which includes 34 countries that contain 80 percent of the world's tropical forests, enabled the researchers to establish a consistent baseline for tracking forest cover change across regions and countries over time.
