In Brazil, forest conservation policies have centered primarily on the Amazon rainforest, given its significance to the actual discussion on climate change. Until 2018, and under a period of rigorous macroeconomic conditions, Brazil had successfully decreased Amazon’s deforestation by strengthening national environmental policies. On the other hand, in 2015, the Brazilian government had institutionalized the Matopiba region, placed in the northeast of the Cerrado biome. In the present study, we used linear and spatial regression models to evaluate determinant factors of land-use change in the southwest region of Piauí, Brazil, placed among Cerrado and Caatinga biomes. We considered determinant factors: distribution and proportions of deforestation and significant temporary agricultural products. Our results show that the natural vegetation represented 69.68% of the total area in 2016. The distance to roads variable does not play a substantive function in defining the deforestation patterns (Coef. = − 0.03). We found that variables as distance to ports, large proprieties size, and land price significantly impact land-use transition models. Also, the study shows that protected areas have reduced the probability of deforestation in the region (Coef. = − 0.22).
