Construction of linear engineering as, roads, ducts and multiducts as roads, has a strong feature of the diversity of land on which they are deployed. This diversity involves properties geological, geomorphological and structural variety. The purpose of this work is to characterize the physical environment in relation to their ability to support the implementation of civil works linear. To achieve this, the use of orbital remote sensing, in this case, Landsat - TM. Interpretative techniques are applied to images in order to assess the forms of relief and drainage found that they can set properties and have built a favorable meaning or not to implement these works. The results and thematic maps presented in this study allow us to promote the geoenvironmental analysis for the planning phase sustainable linear civil constructions (roads and multiducts)

This research presents the result of the engineering geological mapping in a 1:50.000 scale, in Bairro do Peão region, in Piracaia (SP), represented by means of homogeneous units which are susceptible to superficial dynamic processes. To serve as basis for the elaboration of a Chart of Susceptibility to Processes of Superficial Dynamic, a series of physical samples was collected, considering erosive processes and registers of information of usage and soil occupation. The procedure used for elaborating the geotechnical chart is based on Vedovello (2000), which suggests the physiographic compartimentation of the area through photointerpretation and further geotechnical characterization of the selected samples. The geotechnical characterization of the samples was made by identifying the features and properties of the material and forms of the physical environment determining the geotechnical conditions through geological-geotechnical profile descriptions typical of/ peculiar to each unit defined in the area. Thus, for each unit selected, the susceptibility level was established in very high, high, average and low, as well as the prevalent erosive processes.

Due to the new discoveries of oil and gas reservoirs, and also the increasing production of bio-fuels, the brazilian general pipeline system is being vertiginously extended. On the other hand, there is a lack of clear parameters that would allow a better utilization of the geological-geotechnical studies in the process of environmental licensing of pipeline systems. Therefore, this paper presents guidelines that would orientate the environmental licensing procedures to build pipeline systems, and also the geological-geotechnical studies that would support the characterization of the physical context. The method applied in this study consisted in the existing data survey and in their organization, analysis and review. In doing so, there is a well-subsidy integration of the many steps of the pipeline system implementation, the required environmental licenses and the investigation methods of the correlated physical context. As a result, it’s presented a flowchart of the guidelines, detailing the interaction between the environmental licensing, the geological-geotechnical studies and the phases of the pipeline’s project.

Biodiversity is a result of millions of years of biological evolution, and is the component of the system which supports life on our planet. Besides the intrinsic value of each species, all of them as a whole, as well as of the interactions among the species, and their interaction with the physical and chemical environment, result in ecosystem services vital for supporting life on Earth. Because of that, the science of biodiversity is largely recognized as a priority area of scientific investigation both in developed and developing countries. In Brazil, the research on biodiversity can be divided in three parts: 1) discovery and characterization of biodiversity – including marine and human-altered landscapes – systematics and taxonomy; 2) understanding the functioning of ecosystems and environmental services, including in marine and human-altered landscapes; 3) bioprospecting of the chemical diversity of the Brazilian biota.
