The increasing degradation of the environment and the depletion of natural resources, caused by indiscriminate production practices, by current and unlimited human needs and also misconceptions that natural resources are inexhaustible, make current and future environment situation, a constant concern of national and world leaders. With the purpose to confront these issues and to qualify the cities on the environmental situation in the state of São Paulo, the Department of the Environment created, in 2007, the Program “Município VerdeAzul. This paper aims to the study this program of Unit Water Resources Management Pontal Paranapanema through specific analysis of data representing the efficiency of the program directives and a comparative study between two cities unit with discrepant scores and a survey of the possible causes of obtaining low scores for municipalities participating in the project. For such a method was used that consisted of a bibliographical survey related to the main environmental liabilities Brazilians... (Complete abstract click electronic access below)

Morphometric variables such as drainage density, hydrographic density and topographic texture have been successfully used to describe hydrographic basins. This paper deals with possible relationships among those morphological variables and lithological and altimetric aspects, in order to find a classification of several geographical areas in the state of Sao Paulo, Brazil.-from English summary

The following soil classes were identified in the studied area: Quartz Sands (AQ), Yellow Red Podzolic, Dusky Red Latosol (LR), 'Terra Roxa estruturada' (TE), Lithosol substrate sandstone (Lia) and Hidromorphic (Hi). The dimensional analysis method allowed: a) to group the watershed whose percentage (60%) are showing predominance of the same soil (Quartz Sands) and which located in the same relief; b) to group watersheds with different soil classes, but with similar percentages. -from English summary

The present study is about data characterization and evaluation related to private urban users (legal entity) of the Watersheds of the rivers Piracicaba, Capivari, and Jundiai (PCJ), with the PCJ Collection System, sustained by the Department of Water and Power (DAEE), in order to: provide quantitative numbers about this sector, identifying the cities and economic activities corresponding to the largest water consumers, and determine the sector's share in the total charged contribution. The charge for water use is the most recent and the last instrument which has been implemented for the management of water resources, provided by the institution of the State and National Policy of Water Resources in 1991 and 1997, respectively, regarded as an important step towards the preservation and restoration of water resources. According to the data collected in the PCJ Collection System, the urban sector is the private sector that has the highest number of users in these watersheds (52,95% of users), but with less representation in the financial recovery (only 7%), due to its low water demand in their uses compared to the uses of other sectors. The collected data will also serve as both a parameter for comparing the amount of water used by different economic activities and municipalities in the PCJ watersheds and other locations, and as a tool for water resources management
