The late industrialization, together with other factors, ended up directing much of the rural population to cities, without adequate planning, resulting in high density and irregular settlements in risk areas to low-income population. The man settled in the urban site to break environmental laws that eventually causing an imbalance in the natural environment, causing or exacerbating the shortage in availability of water resources. This situation also happened in Presidente Prudente, especially in the east, the focus of this research. Therefore, this study aims to understand the causes of degradation of waterways in urban areas, focusing on society's relationship with nature and its consequences on environmental quality and quality of life of urban population located in the watershed of stream of Gramado, Presidente Prudente - São Paulo. In this catchment there is the irregular deposition of solid waste in the valley, remnants of old pollution release of domestic sewage and industrial (currently collected and intended for treatment), accelerated processes of erosion in some areas of intensive use of the relief and consequently, the bed siltation of streams that are part of the basin. The quality of urban life was seen through socioeconomic and environmental indicators, which were identified through questionnaires to residents, according to local residence in the landscape, divided into three segments: the tops 60 residents, 90 residents and 112 residents in the areas in valley bottoms. With these data we can relate them to the degradation of the basin and aggregate them to the quality of life of residents. Field studies were needed to visualize the changes that occurred in the watershed over the past three years, with the implementation of works aimed at improvements to the community as the conduit stream of Gramado and construction and operation of Sewage Pumping Stations...

Currently the mobile services represent an essential tool in daily life of the population. However, while offering greater convenience to its users, there is growing concern about the harmful effects to human health, derived from daily exposure of the public to electromagnetic fields from radio base stations (RBS), since even today, there is no study proving that longterm exposure to low-level fields are not harmful to health. In Presidente Prudente has not been a study reporting values of measurements of electromagnetic fields from base stations installed in the city. Based on these data, this study aimed to assess the levels of electromagnetic exposure in the city of Presidente Prudente regarding recommended by international bodies, as well as propose measures that can reduce public exposure to electromagnetic fields. For measuring values of electromagnetic fields, we used appliance Electromagnetic Field Meter Portable Digital - DRE-050, the Instrutherm, following the methodology suggested and adapted from the Adilza Condessa Dode’study. In total, 49 points were mapped corresponding to the areas at risk of exposure to electromagnetic fields generated by the substations of power grid, transmission towers and telecommunication towers located in the city of Presidente Prudente (SP)

Over the years, the concern with the detection of the levels of radionuclides in the environment has increased, given that they are carcinogenic to the human respiratory system. Present in the air, waters, soil and building materials, among other substances, radionuclides are unknown by most of the population. In this paper, we present the radioactive gas 222Rn, predominant element among all others and one way of detecting it in an example study of the waters of the Presidente Prudente - SP, through the plastic detector called CR-39. Likewise, we realized the need to approach this issue more broadly in schools and even in higher education, since this field of modern physics and environmental physics usually appears only in master's and doctorate. Thus, we attempted to perform the didactic transposition schooluniversity, through the construction of an object Educational, OE, to be placed on the Bank for International Educational Objects - bioethanol and by developing this contribute to the knowledge and understanding of the importance of monitoring of radioactivity in a way accessible to the population as a whole

The environmental issue has been considered of fundamental importance for the well being of the present and future generations and is inserted into the commitment of political parties at federal, state and municipal government programs, into the interests of popular organizations and business planning. The Parque Ecológico Cidade da Criança is one of the most sought after places for visitation at Presidente Prudente – SP. Located outside the Raposo Tavares Highway, next to the exhibition grounds and beside the agricultural school, has more than 30 acres of area with an infrastructure designed for recreation and leisure activities for all ages and has received new investment of the public power. Given the importance of the ecological aspects, the objective of this work is to perform an environmental diagnosis in order to be able to submit proposals for solving the problems encountered and improve the use of the environmental resources. Therefore, the study was divided into three foci: sewage disposal, erosion process and control of the stormwater drainage system. It was checked the discharge of sewage from the restaurant on exposed soil, erosion processes that develop at the camel and llama cages ground and erosion processes resulting from the convergence of the stormwater in the highest region of the park. Based on these studies, proposals of solution were made for each case, having considered the effectiveness of the project

Environmental diagnosis fits in analysis social-spatial organization insofar it contributes to understanding past and present aspects of how a territory works as well as enables the creation of statements for future ordainment. In this context, the present study aims at contributing with data for creating recovery and environmental preservation projects for the basin of Macacos‟ stream‟s headwaters, located in the north of Álvares Machado county in São Paulo state. To achieve this purpose, the main characteristics and existing uses in the basin have been analyzed and its main environmental problems were identified in the data and information collected in journals, field work and interviews with dwellers from the interested area and local government authorities. On this way, a diagnosis of the environmental state of the studied area was performed considering its specific issues regarding the natural and physical process as well as human influences. From the analysis carried out it was possible to identify environmental impacts on different levels resulting from the conflictuous relation between uses and occupations and the natural dynamics of the studied basin.

This work presents results of art state that searched articles to bring in its wake the relationship between Teaching of Chemistry (TC), Environmental Education (EE) and the Teaching of Chemistry directed from the Science Technology and Society (STS) standpoint. The research was carried by articles surveying in major magazines Brazilian Environmental Education and a reference in the research magazine of Science Education, being performed a qualitative analysis of those items that were identified. It was noted that little is produced on the subject of interest within this field, in mid-1998 to June 2012. In the articles analyzed did not find a perspective that allied relationship STS and EE, or EE, STS and TC. Nine articles were found in relation EE and TC, and TC and three articles STS, constituting two thematic axes: Relationship between Environmental Education and the Teaching of Chemistry and Relationship between Science and Technology Society and Chemistry Teaching, The discussion was given from the contents that comprised the categories created. The first axis involved: a) Teacher of Chemistry and EA b) Contents of Chemistry and EE, and c) Concepts and practices of EE Chemistry teachers. The second axis of the categories are: a) formative processes and conceptions of chemistry teachers in STS: b) Analysis of TC practice focusing STS. There were works produced by the same authors, who mostly used the same theme in different magazines for publication only changing the perspective of analyzing the results. Finally, a scenario indicates that restricted thematic research and the need to advance with future work

The development of the sugar and alcohol sector and its sugar cane cultivation has been given in an accelerated way in Pontal do Paranapanema, mainly from the last decade, and with this has taken quick changes in the dynamic socio-economic and environmental of the region, further accentuating some conflicts and dilemmas social and environmental legacy. This work was done in order that these issues are further explored, that of moving towards a greater theoretical-scientific maturity, and even has a better apparatus to support measures (corrective or preventive) that show required anti such conflicts. For this purpose, we used the environmental licensing as a means of doing this analysis, since it is one of the main instruments of control/ regulation of the State against the development of activities of the sugar and alcohol sector. We also used a little of the vast potential of information that is contained in the environmental agencies. In this case, we used six Environmental Impact Study / Environmental Impact Report (EIS /EIR), six Preliminary Environmental Reports(PER), five Characterization of Enterprise Memorials (CEM), among other documents /studies present there. Some of the information, organized and made available in this work, has even greater potential to be exploited. It was also made an essential literature survey and of the laws related to licensing and alcohol and sugar sector

The concern with the environmental planning has become important in Brazil recently. Until then, nature was conceived as a resource, because of the implementation of developmental policies that perdured to the 1970s, based on the expansion of the industrial complex, altogether hadn´t preoccupation by the federal government with the relationship between society and nature. During this period, after the threat of not receiving more international investment to finance large projects in the country, accompanied by pressure from civil society organizations, the federal government began to take some action related to the environment, such as the creation of federal agencies (IBAMA), application of environmental laws and decrees in order to create rules for the proper use of natural resources such as water, soil and air. From the decade of 1990 onwards the master plans have become a mandatory document for all municipalities in the country with a population over 20,000 inhabitants, ranging from health issues to the development of urban, rural and environmental planning. Thus, the environmental planning gained prominence in the political scene. Therefore, to achieve environmental planning is necessary to follow some social and environmental parameters, which for this survey, conducted in the District of Ameliópolis – Presidente Prudente...
