Pipelines are linear construction that intersect several environments, requiring integration of environmental and technical aspects in its various elaboration steps. Environmental impact assessment if made to integrate the environmental information to enable environmental characterization, possibility identify previously fragilities of environment what contributes to the safety forecast of the significant impacts. These studies shall consider superimpose of the elements and the worsening of critical situations that already exists. In this way, meet and analyse informations about the environmental impact assessment, constructive aspects related to pipelines transport and get environmental impact studies of the case studies, providing the student a critical vision for the discussion of the apropiate balance between description and analysis, methodological rigour and the interface between construction and the environmente with inserts. Performing the critical analysis of methodologies and applied criteria for the environmental diagnosis and impact identification, search improve the methodologies for elaboration of environmental impact studies for linear construction, particulary pipelines, minin conflicts and giving security for the license process. Await provide subsidy to direction data collection, for choosing environmental indicator and for the prognosis and indentification of impacts.

Uberaba municipality, Western Minas Gerais State, has a great geotouristic potential, regarding its geological heritage. The igneous rocks from Serra Geral Formation are found in 12 points, highlighting Ponte Alta (40 meters) and Peirópolis III (7 meters) waterfalls. The sedimentary rocks from Uberaba Formation were described in 11 points, especially Giovane Cave and Waterfall (12 meters). In Marilia Formation sedimentary rocks, the Caieira outcrop (three-meter cave with stalactites and stalagmites) and Vale Encantado Waterfall (8 meters) can be pointed out, among other 8 spots. After the geodiversity assessment, an environmental diagnosis was conducted throughout the potential geotourism attractions, by using the Visitor Impact Management Method. The results indicate that only Vale Encantado Waterfall presents a moderate impact, the least when compared to 22 other sites, exhibiting high or worrisome impact, and 7 with very high impact. In addition to setting the management strategies, and monitoring the environmental impact indicators, this work provides the basis so that activities in the potential Geopark of Uberaba (MG) can be conducted with environmental responsibility and / or geoconservation.

Nowadays, there is a search for knowledgment that could be applied in the solution of the problems caused by petrolific activities involving the environment, like the biodiversity preservation and the ecosystems monitoring and management. Foraminifera (Protista) are used as an important tool to the environment characterizarion, because they answer quickly to the fisic-quimic variations and indicate local alterations. The goal of this job is to create models of foraminiferal communities composition through the screening of subsuperficial samples obtained from a core collect from Bertioga Channel, Baixada Santista (SP), trying to understand the influence of the environmental variations along the time upon the indicator species presence, as well as making paleoenvironmentals reconstructions of the area. A 80 cm-core was removed in the outer edge of marsh adjacent to Bertioga Channel, not far from the confluence with the Itapanhaú River. There are presented in abundance, equitability, diversity and species richness obtained in nine samples along the sediment. The lower part of the core is compound by calcareous species (rotalideos and miliolideos) with domain Ammonia (Biofacies 1) and the intermediate and upper parts contain mainly agglutinated species (Biofacies 2 and 3, which is dominated by species of Ammotium). The qualitative and quantitative study of the microfauna of foraminifera present in the core reveals that in recent decades the sampling area passed from a condition of infra-marginal strip under significant coastal marine influence for the condition of inter-coastal swamp covered with mangrove vegetation. This change indicates that the site has undergone a process of sediment progradation, a phenomenon that may have been timely, localized, or a reflection of a relative fall in sea level at the regional level

Interessada em atividades com foco conservacionista, a Ong SOS Cuesta Botucatu foi selecionada pelo programa Petrobrás Ambiental para desenvolver o Projeto Córrego da Cascata no município de Botucatu. Este projeto é uma proposta de mobilização e educação ambiental para envolver a sociedade, principalmente a população ribeirinha, na gestão e no planejamento estratégico de recuperação e conservação ambiental da Microbacia Hidrográfica do Córrego da Cascata. O foco do projeto é promover a reversão dos processos de degradação e planejar ações estratégicas integradas e participativas de manejo e de gestão para a preservação da qualidade ambiental desse córrego urbano, por meio de uma caracterização socioambiental da referida Microbacia. Em relação à caracterização ambiental, o presente estudo refere-se ao levantamento da mastofauna em fragmentos de Mata Atlântica situados na área da Microbacia. O levantamento dos mamíferos terrestres de médio e grande porte foi realizado no período de abril de 2011 a fevereiro de 2012, com a utilização de dois métodos: parcelas de areia e câmeras trap. Outros dois métodos complementares também foram utilizados na tentativa de conseguir resultados que, invariavelmente, não seriam obtidos com as metodologias acima, como entrevistas e registro de atropelamentos. O objetivo é avaliar a riqueza da mastofauna da região comparando com trabalhos anteriores feitos em fragmentos com características semelhantes aos inseridos na Microbacia do Córrego da Cascata, Botucatu, São Paulo. Foram registradas 14 espécies de mamíferos pertencentes a sete Ordens distintas, sendo duas espécies consideradas ameaçadas. Houve predominância de registros de animais generalistas/oportunistas em áreas com menor diversidade de mastofauna

There is a demand to incorporate the nature in the city in order to meet the wishes of the entire population. The valuation of water, a key component of the quality of the landscape, becomes a key element in this context both for its ecological potential because of their potential for recreational activities. The areas that suffer most impacts are the Permanent Preservation Areas (PPAs) and this paper will be a weighting on the urban interface - PPA. With the study area the basin of the stream of Limoeiro, in the context of the Friendship Fountain Balneary, especially the source contained between residential neighborhoods Maré Mansa and Parque Imperial, the city of Presidente Prudente and Álvares Machado, Sao Paulo, this paper aims to search and use of knowledge about technologies and techniques of environmental restoration, with emphasis on bioengineering, through an environmental characterization of the basin, with a view the incorporation of nature in the lives of the urban population. The methodology includes: literature review priority issues related to the PPAs, linear parks, relevant environmental legislation, environmental characterization of the watershed of the stream Limoeiro; study of technologies and techniques for environmental remediation of soil bioengineering and implementation of parks linear, development of proposals for the environmental recovery of PPA in the basin of the stream Limoeiro, focusing on emerging...
