Modelling Deforestation in Amazonia n High coefficients of multiple determination were obtained on all models built (R 2 from 0. 80 to 0. 86). n The main factors identified were: ¨ ¨ n Population density; Connection to national markets; Climatic conditions; Indicators related to land distribution between large and small farmers. The main current agricultural frontier areas, in Pará and Amazonas States, where intense deforestation processes are taking place now were correctly identified as hot spots of change.
