Within the past two decades, the forests of Brazil have undergone widespread and large scale clearing. The clearing of tropical rainforests may have serious global and local consequences. Global effects include a decrease in biodiversity with the elimination of plant and animal species; increases in atmospheric carbon dioxide, which may affect climate; and disruption of hydrological regimes. Local effects include soil erosion, siltation, decreases in soil fertility, loss of plant cover and extractive resources, and disruption of indigenous populations. Nowhere in the Brazilian Amazon has deforestation increased at a faster rate than in the state of Rondonia. Deforestation in Rondonia has grown at increasing rates during the past decade mainly because of official colonization schemes, road construction, and the subsequent settlement of farmers. This paper contains a historical summary of colonization and road construction in the Amazon Basin of Brazil relative to deforestation in Rondonia. 60 refs., 11 figs., 14 tabs.
