Geotecnologias aplicadas à gestão de bacias hidrográficas e certificação ambiental: estudo de caso da empresa Palma Sola S/A

Abstract

The current study aims through some geotechnologies generating a data basis characterized with three hydrographic basins which are inserted in the Palma Sola S/A properties that works with logs in the county of Palma Sola. After characterizing the basins, it has been mapped the properties and it has been analyzed their representativeness in such basins, besides establishing conceptual basis needed to understand the matter. The work has aimed also to subsidy the environmental certification for the company which has acquired the FSC international seal, adjusting to the legislation encouraging the good practices of deforestation management. It has been made the proprieties digital maps of soil use and occupation, following the INCRA (Institute of Colonization for Agrarian Reform) technical policies for geo-referencing of rural properties for registration of the property, maps of use and soil occupation of hydrographic basins, maps with hydrographic and use of the soil in areas of permanent preservation, hypsometric maps, declivity and Numerical Model of the Terrain of hydrographic basins, 3D view and the profile of the hydrographic basins. The data obtained allowed to consider that the geotechnologies are a great tool in helping the environmental planning of hydrographic basins and forest certification, they generate information that answer the FSC principles and help on the reduction of environmental impact in hydrographic basins. The forest certification appeared as a great inductor of forest management good practices according to the environmental legislation.
