Description: Remote sensing techniques can significantly contribute to environmental monitoring of the low cost mineral extraction of sand pits. This study aims to evaluate the increase of sand pits mining activity between the period of 2004 to 2009, in municipalities of the Paraiba do Sul basin of São Paulo State, Brazil, that are not included in the mineral zoning of this basin. Visual interpretation of Landsat-5 (Thematic Mapper ? TM sensor) images indicated areas of sand extraction for the municipalities of Aparecida, Cachoeira Paulista and Roseira with an annual average increase of 10.1 ha, 20.5 ha and 33.5 ha, respectively. The municipality with the highest percentage of sand mining area increase was Lorena (233%). Results presented in this study can be used to justify the mineral zoning expansion to these municipalities.
