Abstract

The region known as MATOPIBA (Region of the boundaries of the States of Maranhão, Tocantins, Piauí and Bahia) has, in recent decades, undergone strong changes in its natural vegetation due to the advance of Agribusiness. The Cerrado has given way to pastures and large-scale agriculture. This work aims to compare the advance of agriculture over 30 years, with a special focus on how each class of vegetation has been affected, either through direct replacement by agriculture or due to indirect impacts. For this, environmental scenes produced by the classification of Landsat sub-scenes [5 and 8] were used. Based on those images “Losses and Gains” graphics produced by the LCM (Land Change Modeler) model belonging to the IDRISI Selva software were analyzed. As a final result, an expansion of Agriculture over certain types of native vegetation were observed and the progressive decrease in the density of preserved vegetation were identified as a side effect.
