“…Dinamica EGO is a free platform available at the website of Federal University of Minas Gerais. It is used to develop from simple to complex spatial models in different environmental studies COSTA, 2009), such as the one focused on investigating deforestation dynamics in agricultural frontiers (MATRICARDI et al, 2018), and future projections on deforestation (CRUZ; BLANCO; OLIVEIRA JUNIOR, 2021), as well as on performing biodiversity and biogeography analyses (OLIVEIRA et al, 2019), analysis of areas susceptible to floods (RIEGEL et al, 2021), of fire incidence likelihood (SAHAGUN-SÁNCHEZ, 2021) and of urban water demand scenarios (ALMINO; RUFINO, 2021), among others. Thus, the aim of the current study was to simulate the spatial-temporal dynamics of deforestation in the area covering the Caatinga biome in Piauí State, for the next five decades.…”
