Sample text

Each image covers a 184 × 184 kilometer square, requiring 229 images to cover the whole of Legal Amazonia. Under cloudy conditions, INPE makes the assumption that the deforestation level is the same in the cloud-covered areas as that in the visible parts identified in the image (Faminow, 1998). 3. Approximately 44 satellite images, or around 20 percent of the total of 229 that cover the whole of Amazonia. These critical images are used to generate partial estimates of gross deforestation throughout the region.

Assuming (a little exaggeratedly) that fallow areas are utilized basically for seasonal livestock rotation, pastures could account for the occupation of up to 88 percent of the deforested areas. Compared with 1970, 91 percent of the increment of the cleared area has been converted to cattle ranching. More detailed analyses would be needed to elucidate changes in land use over time, the predominance of certain uses over others and the eventual stabilization of certain uses over time. These analyses have not been attempted here, but a number of econometric studies have been carried out on these lines (Reis and Margulis 1991; Pfaff 1997; Andersen and Reis 1997b; Ferraz 2000; Andersen et al.

Intensified ranching can also be observed visually when the maps below, showing the geographical density of the cattle herd in Census Years 1970 and 1996, are compared (Figure 3). Socioeconomic Benefits from Deforestation: Early Evidence The data thus far presented demonstrate the dynamism of the rural economy in Amazonia in the last decades. It would be critical, however, to analyze whether the activities which lead to deforestation in the region generate more welfare gains than the social, environmental and economic costs involved and whether these gains benefit in some relevant way the poorer population groups.
