Identificação de áreas indubitavelmente da União na gleba Palmeirante como instrumento para gestão de políticas ambientais

Abstract

The federal government in recent years has been trying to advance land regularization in areas of its dominance, especially those located in the Legal Amazon, in order to ensure that the properties of the Union fulfill their socio-environmental function. The present study aims at the compatibility of environmental policies, such as the rural environmental register (RER), with the policies of management of the Union's assets, such as the delimitation of the undoubted areas and the land regularization of these. The identification of these indubitable land ranges considered inalienable on the banks of the federal Tocantins river in the Gleba Palmeirante was carried out using geotechnologies such as remote sensing and geoprocessing techniques, applying the morphological prediction methodology that is being used in the Planning, Development And Management Ministry for delimitation of these areas. This methodology consists essentially in the use of the Otto Bacias database generated by ANA(NWA) - National Water Agency. After identification and selection of the basin, the vector data was used as a polygon to cut the SRTM data produced by NASA and made available by INPE, thus generating the Digital Elevation Model used in this work. With the MDE mounted, treated and trimmed by the reference basin, the Saga Wetness Index algorithm was applied, which is to identify concentration environments. This algorithm is similar to the topographic index of humidity, which aims to identify environments with water saturation. The methodology of morphological prediction proved to be efficient in identifying the undoubtedly areas of the Union in the Gleba Palmeirante. This fact was confirmed by the characterization of the soils of the region, because the soils found in the undoubted range (flossic neoses, plinthsols, and quartzarenic neosols) have poor drainage and presented high humidity indexes, close to the final modeling index, which was 26,36. The Permanent Preservation Areas were also delimited according to the Brazilian Forestry Code, through which it was possible to verify that the entire GPA of Gleba Palmeirante is inserted in the area undoubtedly of the Union. Therefore, the present study aimed to propose according to Established in Law No. 11.952 / 2009 the land regularization of these areas, inserting clause delimiting the permanent preservation area and its current status in the CDRU title, these data can be obtained from the rural environmental register. In addition, environmental charges are also created, setting deadlines for the recovery of degraded APP or for preservation of these areas, under penalty of cancellation of the concession title of real right of use. The delimitation and regularization of these areas undoubtedly aims to contribute to the environmental policies for the monitoring, restoration and conservation of permanent preservation areas on the banks of the federal river Tocantins in order to guarantee the ecological and environmental functions of these areas.
