Description:	As examples of human activities that may provoke changes in the stability and in the dynamic equilibrium of the river basin system, we have deforestation, burned areas, predatory agriculture, urbanization and other ways of soil occupation without any environmental planning. The combination of remote sensing (TM Landsat and CBERS images ) and geoprocessing products and techniques are valuable tools to subsidize studies of the land use. The results in this first stage of the project indicate a relation between the increasing of the conductivity in the water of microbasin with the increasing of the plantation areas of grains and the decreasing of the primary and secondary forest areas (Capoeiras). The results show that the changes in the use of the land are provoking an increase in the concentration of the nutrients and a consequent diminution of the water quality of the Igarapé Cinqüenta e Quatro
