Geotechnology application for data acquisition for agricultural and environmental management of the municipality of vitória Brazil-sp

Abstract

The present study aimed at associating geoprocessing procedures for analysis of land use and native vegetation for municipal management, using an easy access and low cost methodology to the public administration of the municipality of Vitória Brazil/SP. Initially, the land use and the land occupation were evaluated, being delimited the municipal hydrographical micro basin and the permanent preservation areas (PPAs). For this purpose, multispectral images of high spatial resolution were used, available by the government partnerships between the City Hall, the state and federal authorities. From the obtained results it was possible to efficiently determine that only 3% of the original vegetation is preserved; the livestock is the main municipal occupation, covering more than 41% of the area; citrus and sugar-cane are also very expressive, occupying, respectively 13% and 7% of the area of the municipality of Vitoria; and around 70% of the municipal PPAs need hydrophilic species for its recovering. These indicators configure a data bank for consulting and supporting the public admiration, as well as a source for the administrative decision making, aiming at guiding the resources for the development of the municipal rural sector, in a more dynamic, efficient and economically viable way.
