- Abstract
The objective is to analyze the growth of permanent and temporary crops in Piauí biomes, pointing out the changes that these crops caused in the vegetation cover of the state of Piauí. For this purpose, data from the Municipal Agricultural Survey and satellite images from the Project for the Annual Mapping of Coverage and Use of Soil in Brazil (MapBiomas) were used, referring to the period from 1985 to 2019. The results revealed that permanent plantations practically did not alter the natural cover in the study area. The Savannas represent the most suppressed type of coverage, while in the Caatinga, the main transformations resulted from the use of the land for pastures. In the Cerrado, temporary plantations caused the greatest transitions, especially with regard to soy. Therefore, it is suggested to intensify the monitoring of soybean growth in the south of the state of Piauí.
