Harrison Road, Room 101East Lansing, MI 48823(matricar@bsrsi.msu.edu; pedlowma@uenf.br)During the 1970s, the Brazilian federal government started a massive program ofcolonization projects in the Amazon to decrease increasing population and politicaltension in the middle south of Brazil. As a result of such colonization projects Rondonia,a state located in the western portion of the Brazilian Amazon, faced an explosivepopulation growth that led to rapid deforestation due to logging, mining, farming andcattle ranching. Deforestation increased significantly in Rondonia since the 1970s;growing from 4,200 km 2 in 1978 to 30,000 km 2 in 1988, and has reached 53,300 km 2 in1998. On this study, we analyzed deforestation on conservation units located in Rondoniausing remotely sensed data and thematic covers provided by the Tropical RainforestInformation Center of the Michigan State University and by the Rondonia Secretariat ofEnvironment. We measured deforestation for all protected areas located in Rondonia for1992 and 1999. We also conducted analysis on the most impacted conservations units on1992, 1996, and 1999. Moreover, we conducted a case study on the Bom Futuro NationalForest, which presented the highest deforestation in Rondonia, using satellite data for1992, 1996, 1998, 1999, and 2000. On Bom Futuro we carried out a correlation analysisof roads and soil types with deforestation totals and performed an approach to define riskzones of deforestation. The results of this work provided useful information to agenciesinvolved in defining strategies to preclude the continuation of the present trends ofdeforestation on conservation units in Rondonia.
