Abstract

Meteorological satellite data were acquired for the southern portion of the Amazon Basin of Brazil in 1984 and 1985. Analysis of these data for the states and territories of Mato Grosso, Rondonia, and Acre has documented a substantial increase in the rate of forest conversion or deforestation from 1984 to 1985. The 1985 data indicated that the deforested area within the states or territories studied totalled 89 000 km2 while the area of forest disturbance totalled approximately 265 000 km2. The forest disturbance area is the bounded area within which deforestation is actively taking place. Data from 1986, while not as comprehensive as the 1984 and 1985 data, indicate continued expansion of large-scale deforestation in many areas of the Amazon Basin south of the Amazon River. Multiplicative increases in large-scale tropical deforestation were associated with the establishment of all-weather roads.
