Mapeamento e análise das unidades de conservação na faixa de proteção do lago de Itaipu

Abstract

Conservation units are of great importance for the preservation of biodiversity, acting as ecological corridors, protecting endemic or endangered species, as well as allowing interaction between individuals from different fragments, favoring gene flow. Brazil has a significant number of registered Conservation Units classified as Full Protection or Sustainable Use. Paraguay has several conservation units classified as Federal Units or Private Units. This work aims to map and generate georeferenced data on the Conservation Units around Lake Itaipu, both on the Brazilian left bank and on the Paraguayan right bank. In the first methodological stage, data was collected by accessing Brazilian and Paraguayan legislation and carrying out bibliographic research on the websites of official bodies. In the second stage, which involved drawing up the maps, the QGis Desktop 3.32.1 program was used for georeferencing, calibrating the boundaries and drawing up maps of the use and coverage of the Conservation Units. Data from the MapBiomas Brasil and MapBiomas Bosque Atlântico websites was also used to capture satellite images of the Conservation Units. The mapping results made it possible to identify the temporal evolution of land use and cover between 1985 and 2020 for the eight Units on the Paraguayan side and the two Units on the Brazilian side.
