                         last few years have varied by a factor of four. Reliable estimates 
                         are needed because of deforestation's contribution to global 
                         concerns such as greenhouse warming and loss of biodiversity. A 
                         new estimate for forest area cleared through 1989 (Tardin et al., 
                         1990)provides a much more reliable point of reference than was 
                         previously available, and permits the re-evaluation of previous 
                         data to drive deforestation rates. In the recent study, 222 
                         LANDSAT Thematic Mapper (TM)images covering all of the forested 
                         portion of Brazil's Legal Amazon region were interpreted manually 
                         on color composites of TM bands 3,4 and 5 at a scale of 1:250,000. 
                         The measured deforested area in the region covered by the map 
                         sheets of that work was 394,722sq.Km. Inclusion of small 
                         deforested areas in the remainder of the region (totalling 
                         1,930sq.Km), and adjustment for cloud cover, weighted by 
                         deforestation extent for each image, yields a best estimate for 
                         the deforested area by 1989.",
