A temporal analysis of land use and cover in the para river basin after the implementation of 1988's federal constitution of brazil.

The present research aimed to analyze the land use and cover of the Para River Basin territory, located in Minas Gerais, Brazil, between the years 1990 and 2020, considering the period after the enactment of the 1988's Federal Constitution, which imposed on the Public Power and the community the duty to defend and preserve the environment for present and future generations. In this sense, we assessed whether the constitutional command that recognizes that everyone has the right to an ecologically balanced environment has been observed. To this end, changes in land use and land cover (LULC) were quantified, using as database classified images provided by the MapBiomas Project. These analyzes were performed through the application of landscape metrics and the Land Change Modeler (LCM) tool, to determine the spatial pattern assumed by the LULC classes and define the contributions of each class to the landscape changes. The temporal analyzes reveal that the vegetation cover has been explored without the concern of replacing the native vegetation and demonstrate that the environmental constitutional commands haven't had a positive impact on an ecologically balanced environment in the study area.
