Comparação de eficiências do uso de sistemas construídos de áreas alagadas (Constructed Wetland Systems - CWS), tipos ascendente e descendente, para tratamento de efluentes

Water is an essential element for life. The use of this element, to support the community, defines it as water resource. This feature is being misused and degraded by the dumping of highly contaminated effluents. The impoverishment of its quality poses a risk to human consumption. The necessity to manage this resource, treating the wastewater properly, requires the constant improvement of treatment systems. Another need is to adjust the cost of systems to the demands of communities with less financial clout. This study aimed to adapt and understand the systems of wetlands, improving its efficiency, in an attempt to collaborate with the enrichment of this technology. The practical evidence, with lab-scale prototypes, assembled in ETE Piracicamirim with urban sewage effluent contributed to highlight the problems and operating system design. The bibliographic review showed that several studies had effectiveness for treatment. But it was evident the need for better understanding of dimensioning definitions that better attempted to the answers into the project. Moreover, standardization of system conditions for the specific wastewater treatment is an interesting field, identified, for future studies yet contribute to environmental engineering and sanitation

Sensibilidade ambiental fluvial a derrames de óleo e biocombustível: vulnerabilidade e impactos à mastofauna

O trabalho apresentado é constituído de dois capítulos distintos, ambos com preocupação recorrente de realizar uma ciência que tenha interface com a realidade, uma Ecologia aplicável às questões e demandas da sociedade contemporânea como ferramenta para compreender a realidade, mediar conflitos. No capítulo I - Integrando o meio físico, biológico e sócioeconômico na proposição de novos Índices de Sensibilidade Ambiental (ISA) propomos o desenvolvimento de índices que combinem aspectos bióticos, socioeconômicos e ecológicos como: a) Índice de Sensibilidade Ambiental Biológico (ISAB), pautado na comunidade de mamíferos de médio e grande porte; b) Índice de Sensibilidade Ambiental Socioeconômico (ISASE), composto pelo tipo de atividade econômica e pelas características da comunidade do entorno e c) Índice de Sensibilidade Ambiental Ecológico (ISAEc). No capítulo II - Contribuição da área do fragmento e dos corredores ecológicos para a comunidade de mamíferos de médio e grande porte das matas ciliares, ressaltamos a importância da Ecologia da Paisagem para a presença/ausência de espécies de mamíferos de médio e grande porte. Quais correlações são relevantes e como as métricas da paisagem têm influência sobre a comunidade da mastofauna. Há a clara intenção de compreender a realidade e propor soluções para as problemáticas modernas visando o bem estar da sociedade e a conservação e preservação da biota

Diagnóstico ambiental do município de Ipeúna: subsídios para o planejamento do turismo

Contextualizing the theme of sustainable tourism, or ecotourism, the reality of the city of Ipeúna, there is the incipient state of efforts in this activity because, predominantly, its territory is occupied by the monoculture of cane sugar and pastures, which damages the maintenance of vegetation fragments, as well as degrading areas that often could take a value tour. Through environmental planning, was intended to raise major issues of interface tourism / environment in order to seek alternatives to the implementation and development of tourism in Ipeúna. As a result, it presents an environmental diagnosis of the study area through which to assess the current status of tourist attractions in relation to environmental and socio-economic dynamics of the city.

Levantamento da mastofauna terrestre de médio e grande porte ao longo da Rodovia Alcides Soares, Botucatu-SP, como subsídio para ações de conservação

Atropelamentos associados à fragmentação dos habitats naturais, tanto para construção de estradas, quanto para agricultura, são uma das principais causas de mortalidade para várias espécies de animais silvestres pelo mundo todo. Durante o período de agosto de 2011 e junho de 2012, em um trecho da Estrada Vicinal Alcides Rodrigues Soares do município de Botucatu, interior do estado de SP, foi realizado o levantamento de mamíferos terrestres de médio e grande porte através do método de parcelas de areia e transecto, além da procura de carcaça de animais atropelados. Espécies como Onça-parda (Puma concolor) e Tamanduá-bandeira (Myrmecophaga tridactyla), ambas em situação vulnerável de extinção, foram registradas em proximidade da estrada. Através dos dados obtidos, tem se como objetivo demonstrar a importância da valorização da fauna local, com a construção de passagens de fauna, como uma das medidas para a sua conservação e consequente redução dos diversos distúrbios e impactos causados por estradas

SIG e álgebra de mapas na elaboração de um mapa de potencial de erosão em áreas de silvicultura

Cette étude visait à générer une carte du potentiel d'érosion pour la Ferme Santa Edwirges, située à Lorena /SP. Les résultats ont etés classifiés en faible, modéré, élève et très élève potentiel d'érosion et la carte obtenue a été comparé par rapport aux autres cartes existantes pour la zone d'étude. La méthodologie proposée se basant sur une application qualitative simple L’équation Universelle de Perte de Sol (USLE ou EUPS), en considérant les parties de l'équation: érodibilité, la topographie et l'utilisation des terres. Les donnés ont etés intégrés par l'algèbre de carte dans l’environnement SIG de ArcGIS. Pour la représentation de chacune de ces parcelles, nous avons utilisé une carte des formations superficielles de la ferme, généré à partir d'une ré-interprétation de la carte géologique, une carte de la pente et une carte d'utilisation des terres, attribuant un poids d’important pour chaque catégorie de ces cartes dans le processus d'érosion et dans l'algèbre proposée. Les résultats obtenus sont compatibles avec les zones identifiées comme les plus critiques sur terrain. La ferme a été identifiée comme de potentiel d'érosion modérée et la partie sud de la ferme le plus critique, suivi du groupe conduit par la zone de cisaillement, par contre les plaines proches des rivières ont eté identifié comme la zone plus stable avec moins de potentiel d'érosionDe la comparaison des résultats de ce travail et d'autres qui ont fait antérieurement dans la zone d’intéresse, qui ont utilisé les paramètres géotechniques dans la représentation de l'érosivité des sols, nous avons pu voir des résultats similaires, en particulier dans les zones à potentiel élevé et faible pour l'érosion. De la discussion et analyse des résultats, la méthodologie proposée à eté validée

Proposta de elaboração de carta de sensibilidade ambiental aplicada a postos de combustíveis em Rio Claro-SP

Leaking of hydrocarbon in fuel underground storage tanks constitute object of concern for urban environmental management, because therefore they provoke damages to the physical, biological and socioeconomic environment. Though laws that regulate this essential activity exist, aiming at to prevent contamination with hydrocarbon, we observe that this still happens. This fact evidences that the selection of places for installation of gas stations has not considered the characteristics of the natural environment, implying in more critical consequences associated to the leaking. The objective of this work is to elaborate a chart applied to the gas stations in Rio Claro/SP. The determination of the Index of Environmental Sensitivity for elaboration of such chart was carried through breaking the selection of factors of Environmental Sensitivity of physical, biological and socioeconomic environment. The balance of these factors was given by means of Ad hoc consultation. The crossing of the information was carried through using the method of overlapping of overlays. The result is a chart that shows us areas with classes of high, middle and low Environmental Sensitivity. One gives credit that this type of material can be used as criterion in the selection of adjusted areas for installations of new gas stations and management of the already installed gas stations. The diagnosis of the current situation of the gas stations in the area and recommendations had also been elaborated.

Diagnóstico ambiental de atividades de mineração com ênfase em olarias no município de Rio Claro (SP)

The environmental diagnosis of any area affected for mining activities contributes in a positive form for the analysis of the characteristics of the environment, biological and social, thus being able to establish control parameters. The clay extration for red ceramics promotes the environment degradation as any another one cultivates of mineral goods, but in lesser scale, which had to the dimensions of potteries. Being thus, some decurrent environment characteristics of the clay extration had been inquired clearly used for potteries located in the city of Rio Claro, SP. For this, the followed method was the cadastre of these areas and potteries in created tables, searching, with this, the contribution for the involved people in the extract activity of related potteries and the facilitation in the visualization of the main problems, necessities and proposals for each one. It could be perceived that the environmental diagnosis of the areas had in common presented referring points to the places where if they find the activities. The same ones are located in the region the northwest of Rio Claro and well next one to the others. Moreover, they have in common, referring characteristics to the process of manufacture of bricks. In common, all the responsibility for the administration and course of the activities competes to the proper families, since the administrative part, even though to the process of manufacture of the bricks. Moreover, from the comment of the areas through field work, the prominent use of diverse areas in the region for the clay extration is noticed, making with that the region has great importance in the regional scene.

Sensibilidade ambiental ao derrame de biocombustível e óleo: uma análise da estrutura genética populacional do Curimba (Prochilodus lineatus)

As atividades humanas vêm causando grandes pressões nos ecossistemas aquáticos continentais e nos organismos que ai vivem, sendo os peixes o grupo mais afetado. Para compreender o grau de impacto sofrido por uma comunidade é necessário conhecer como esta se encontra estruturada. Este estudo foi organizado em dois capítulos: 1) dedicado a compreender aspectos relacionados à comunidade de peixes da represa de Barra Bonita; 2) análise sobre a estrutura genética do curimba (P. lineatus) no rio Tietê, em diversos segmentos antes e depois das barragens. A estrutura da comunidade de peixes reflete a integridade ecológica do ecossistema, uma vez que diversos comportamentos dependem de determinadas condições ambientais. Por se tratar de um ambiente modificado e exposto a diversos agentes impactantes, estudos sobre a comunidade de peixes na represa de Barra Bonita (rio Tietê) se tornam essenciais para verificar as condições ambientais, auxiliando na gestão deste ecossistema. Para uma análise mais profunda das condições ambientais deste ecossistema, foi realizada também uma análise genética da população do curimba (Prochilodus lineatus), uma vez que o conhecimento da estrutura populacional é fundamental para auxiliar no manejo e conservação das populações de peixes nativos. Os resultados das análises populacionais mostraram que a comunidade de peixes encontrada é típica de ambientes represados, sendo formada por uma maioria de espécies de pequeno e médio porte, do tipo restrategistas, com desova parcelada, sedentárias e que apresentam uma alta plasticidade trófica. No entanto, a presença de espécies com algum grau de ameaça mostra que a região ainda mantém espécies sensíveis mantidas provavelmente pelos tributário que deságuam no rio Tietê. Mesmo a comunidade sendo formada por uma maioria de espécies autóctones, a presença de espécies não nativas nos faz pensar sobre a falta de valorização e conhecimento...

Estatuto do índio, direito indígena e impacto ambiental: aldeias Guarani do Jaraguá (SP)

In Brazil, there are three main codes that surround the issue of right or possession of various lands according to concepts of ownership or purchase. When it comes to indigenous issues in Brazil is difficult to say which legal code applies more fairly the native population of the country. In the case of the Indians who have their reserves near urban areas there is such a conflict of laws becomes more evident and takes even greater than in other regions of Brazil. As is the case in the indigenous villages of the District of Jaragua in Greater São Paulo, the Tekoá YTU and Tekoá Pyau. The two villages are located in northeastern São Paulo and currently are surrounded by continuous growth and disorderly city of Sao Paulo while their inhabitants fight to preserve the customs and traditions of the Guarani people. They prevail on the City Statute (2001), the Indian Statute (EDI) Environmental Laws and the National Council of Environment (CONAMA) and the Forestry Code, the latter solely because they are near the State Park Jaragua - area environmental preservation

Aplicação de técnicas alternativas para recuperação de foco eosivo em área rural situada no município de Álvares Machado – SP Presidente Prudente 2012

When handling soil conservation practices isn’t applied correctly, they cause problems at the level of structure, cohesion and fertility in soils and lack of water availability. In the case of this monograph, conducted in a rural property located at Álvares Machado City, identified that most areas are intended for use activities of beef cattle and dairy and subsistence agriculture, which historically addition to withdraw native flora, resulting in problems such as compaction and increase soil exposure to climatic agents, generating a serious frame of erosion problems. In the case of water from rainfall, the soil exposed, causes the “splash” effect and therefore when it becomes runoff carries the spalled particles mainly for low land areas. Without the vegetation, especially trees or shrubs species, the velocity of runoff increases, initiating the appearance of furrows, which consequently may become a kind of ravine erosion and gully, which makes invalid any area in your surroundings...

A política nacional de resíduos sólidos e o plano diretor municipal de Rio Claro/SP: o uso como instrumento para a gestão urbano-ambiental municipal

Due to the large economic development associated with the growing consumerist lifestyle of our capitalist society, the problem of uncontrolled solid waste generation worsens, which one is considered to be one of the main responsible factors for environmental degradation. As a case study and in order to solve the problem of large generation of municipal solid waste, this work aims to study the “plano diretor” of Rio Claro city, São Paulo. The “plano diretor” is a municipal law that provides guidelines for the administration of the city, which include guidelines for the management of solid waste generated in the city. The guidelines required in order to write the “plano diretor” are provided by the national law “estatuto da cidade”, providing information for the planning and development of the cities, as well as the management of the urban environment. However, only the “estatuto da cidade” does not provide enough instructions for creating management plans in order to solve the many problems from the urban environment. Thus, studies have been done about urban and environmental management, to understand how municipal management plans should be structured. As a form of seeking information that can complement the “plano diretor” to the creation of policies for managing solid waste of the city, the “Política Nacional de Resíduos Sólidos”(PNRS) emerges in 2010 as a document which provides principles, objectives and guidelines to create plans for Solid Waste Management at the national, state, regional and municipal levels. Therefore, it was possible to make a joint analysis of the “plano diretor” of Rio Claro with the PNRS to identify what is already done within the municipality about the solid waste management, and identify which aspects are most significant in the municipal solid waste management that the national policy provides. Yet studies have been done on the current municipal solid waste management...

Indicação e avaliação de potenciais áreas para implementação de aterros sanitários municipais – Apuí/AM

About eighty percent of the Brazilian municipalities have their residues in environmentally unsuitable sites and socially insalubrious. In this context, in the year 2010, instituted the National Policy on Solid Residues, which aims to integrated management and management environmentally appropriate of solid residues in Brazil (JUCA, 2002).The problem of urban residues is related to its origin and production in the same way that the concept of inexhaustibility and reflexes of compromising the environment, especially the pollution of soil, air and water resources (LIMA, 1995). Seeking a better residues management in the municipality of Apuí / AM and continuing work already started, Plan Solid Residues Management of the Apuí / AM, this work came to propose a better environmental compliance in relation to solid residues compared to 12305/2010 law that established deadlines / timelines on some actions such as landfills and the consequent elimination of environmentally sound disposal of residues by 2014 and thus began a study of potential areas for the implementation of the landfill were evaluated taking into consideration technical aspects (soil, vegetation, climate, hydrography, etc), legislation and Google Earth imagery. The result of the work over the 6 areas proposed by the City Hall was the choice of AREA 4 as the most indicated for the implementation of the landfill for the city of Apuí, which has 18,325 inhabitants (IBGE, 2011); some considerations were made if a new area can be proposed by the city to implement the landfill

Diagnóstico Ambiental da Cidade de Presidente Bernardes - SP

The new modes of production imposed by capitalism and its relentless pursuit of development triggered several impacts on the natural environment and thereby the quality of life of society. These impacts become more visible when we look the urban place. For the identification and proposal of solutions is necessary to carry out an environmental diagnosis to have knowledge of the real situation of a given area. The Presidente Bernardes city is located in West of the São Paulo State, and even being a small city has many problems resulting of the unplanned urban growth. Thus, the present work intends to conduct an environmental diagnosis of the city Presidente Bernardes-SP, through the analysis of water supply systems, sewage treatment, collection and disposal of solid waste and green areas in the urban area and if required, indicate plausible alternatives to solve any problems
