After the approval of the New Brazilian Forest Code, farmers are required to register their rural property in the Rural Environmental Registry. By April 30, 2017, more than four million farmers were included, an area of approximately 408 million hectares. The collected data add up to hundreds of millions of polygons, requiring a computational effort and geoprocessing techniques to treat the data and turn it into information. The results indicate that the area reserved to vegetation preservation by farmers represents 20.5% of Brazilian territory, thus demonstrating the importance of the agriculture in environmental preservation.  aCadastro ambiental rural  aCAR  aEnvironmental preservation  aNative vegetation  aRural Environmental Registry System1 aCARVALHO, C.
