Full textAbstract:
O etanol de cana-de-açúcar tem se destacado no cenário mundial como uma potencial fonte de energia alternativa aos combustíveis fósseis. Entretanto, sua produção é fortemente baseada na monocultura, intensificando os impactos adversos nos recursos ambientais. Esses impactos podem se combinar e persistir ao longo do tempo, possibilitando o acúmulo destes nos recursos ambientais, tornando-se necessário um planejamento mais adequado da produção do bioetanol, para que uma abordagem mais sistêmica seja integrada a esse processo. Em meio a esses fatores, a consideração de impactos cumulativos é um elemento essencial para a sustentabilidade do etanol, por conseguir avaliar de maneira mais holística as implicações da monocultura, sendo obrigatória durante o processo de licenciamento ambiental do setor. Essa prática pode ser viabilizada por meio da AIA, possibilitando que esses impactos possam ser identificados e avaliados para que a viabilidade ambiental dos empreendimentos do setor possa ser atestada, principalmente pela elaboração de um EIA. Apesar da exigência, há indícios de que a prática da inserção destes impactos não tem sido realizada adequadamente. Diante do exposto, a pesquisa teve como objetivo analisar de que maneira os impactos ambientais cumulativos estão sendo inseridos em Estudos de Impacto Ambiental do setor sucroenergético paulista, à luz dos elementos preconizados pela AIC. Para tal, foram caracterizados potenciais impactos ambientais cumulativos provenientes da monocultura de cana-de-açúcar nos componentes ambientais águas superficiais, águas subterrâneas, biota aquática e fauna e flora terrestre; além da definição de critérios para as análises nos estudos ambientais. Assim, verificou-se a prática atual da consideração desses impactos nos EIAs do setor canavieiro. A metodologia foi baseada em pesquisa bibliográfica, entrevistas semiestruturadas, modelo causal e análise documental. Como resultados, constatou-se que os impactos ambientais cumulativos não têm sido considerados adequadamente nos EIAs, tendo como base os critérios adotados na análise. Dentre as fragilidades encontradas, destaca-se a falta da identificação e consideração nas análises de outras atividades do passado, presente e futuro, bem como a definição de limites temporais. Além disso, observou-se que alguns dos impactos cumulativos identificados pela pesquisa são contemplados nos estudos como impactos diretos e indiretos. Considerando que as monoculturas podem ser caracterizadas como fontes de mudanças ambientais sob ampla perspectiva espacial e temporal, e diante de sua natureza repetitiva, há uma necessidade de estabelecimento de requisitos, procedimentos e métodos a serem empregados para avaliação destes impactos. Neste contexto, os Termos de Referência poderiam direcionar essa avaliação por meio da definição de critérios a serem contemplados nos estudos, possibilitando uma compreensão das perturbações das áreas de cultivo em sistemas ambientais e a definição de limites a serem observados, além de agregar valor aos processos de tomada de decisão sobre a viabilidade ambiental de empreendimentos do setor sucroenergético no estado de São Paulo.Sugarcane ethanol has distinguished itself worldwide as a potential alternative energy source to fossil fuels. However, its production is heavily based on monoculture, intensifying the adverse impacts on environmental resources. These impacts may combine to persist over time, allowing the accumulation of these on environmental resources, making necessary a more appropriate planning of bioethanol production, for a more systemic approach into this process. Amidst these factors, addressing cumulative impacts is an essential element for the ethanol sustainability, able to assess a more holistic manner the implications of monoculture, being required during the environmental licensing process industry. This practice can be conducted through the EIA, enabling these impacts can be identified and assessed for environmental feasibility of projects in the sector can be attested, mainly by establishing an EIS. Despite the demand, there is evidence that the practice of addressing these impacts have not been adequately performed. Given the above, the research aimed to analyze how the cumulative environmental impacts are being entered into the Environmental Impact Statements of São Paulo sugarcane industry in light of the elements recommended by the CIA. To this end, potential cumulative environmental impacts from sugarcane monoculture in the environmental components surface waters, groundwater, aquatic biota and terrestrial fauna and flora were characterized, beyond the definition of criteria for analysis in environmental studies. Thus, we found the current practice of considering these impacts in EIS of sugarcane industry. The methodology was based on a literature review, semi-structured interviews, document analysis and causal model. As a result, it was found that the cumulative environmental impacts have not been adequately considered in EIS, based on the criteria used in the analysis. Among the weaknesses found, there is a lack of identification and the analyze of other activities of the past, present and future, as well as setting time limits. Moreover, it was observed that some of the cumulative impacts identified by the survey are included in the studies as direct and indirect impacts. Whereas monocultures can be characterized as sources of environmental changes on large spatial and temporal perspective, and before their repetitive nature, there is a need to establish requirements, procedures and methods to be employed for the assessment of these impacts. In this context, the Terms of Reference could direct this review by defining the criteria to be included in the studies, enabling an understanding of the disturbances growing areas in environmental systems and setting limits to be observed, besides adding value to decision- making process on the environmental feasibility of the sugarcane industry developments in the state of São Paulo.

Mebine, P. "Minimum environmental impact discharging." Thesis, Loughborough University, 2006. https://dspace.lboro.ac.uk/2134/12945.
Full textAbstract:
Many contaminants exhibit decay. Decay mechanisms include consumption by bacteria or radioactive decay (temporal decay uniform across the flow), heat loss or evaporation through the surface (decay decreasing with depth), and break up by turbulence (decay proportional to the product of velocity and depth). This thesis investigates how the decay of pollutants in a river effects the dilution process and the selection of discharge siting to achieve minimum environmental impact. For a non-symmetric river with non-reversing flow, exact solutions are presented that illustrate the effect on the optimal position for a steady discharge of cross-channel variation in the decay (uniform, decreasing or increasing with depth). The optimal position is shifted to deeper or to shallower water accordingly as the temporal decay divided by flow speed decreases or increases with water depth. When advection dominates diffusion, there are special directions (rays) along which information is carried. For steady, unstratified, plane parallel flow, the effects of decay are allowed for in specifying these special directions. Two special cases are considered. Firstly, for a smoothly varying depth, a general result has been derived for the curvature of the rays as effected by spatial non-uniformity in decay, mixing, flow speed and flow direction. Secondly, for discontinuous variations in depth, diffusivity, velocity and decay, approximate concentration formulae are derived. Ray bending indicates that the downstream propagation of pollutant is principally in the low-decay region. Computational results are used to give pictorial illustration of the concentration distributions and of the difference between discharging at non-optimal and optimal sites.

Full textAbstract:
One of the major tools for assisting in the implementation of sustainable development is environmental assessment (EA). This thesis has sought to develop a model and associated techniques required to provide an effective and efficient EA of projects in the water environment. The challenge has been to integrate a number of disparate elements into a cohesive model that provides workable procedures and outputs. The conceptual elements of the EA process have included the needs of environmental ethics and values; the political decision-making processes; current legislation and policy; the communication of infonnation for a range internal and external stakeholders and decisionmakers; the links with technical and economic issues; and The Environmental Agency's project management systems.

Full textAbstract:
Questions of uncertainty and value conflict are increasingly pervasive challenges confronting policy makers seeking to address the range of environmental problems generated by contemporary technological systems. Yet these questions are ultimately political and moral in nature, and require a framework of strategic environmental assessment (SEA) that is marked by informed and democratic civic governance. Reflecting this, the original, civic purposes of environmental assessment (EA) embraced science and public participation as interdependent elements in the creation of more sustaining forms of human-nature interaction.
However, formal models of EA have forsaken meaningful democratic engagement to technique. Based on the instrumentalist assumption that better science automatically leads to better policy, EA has externalised the civic source of political energy that underpins its environmental expertise. Moreover, debates become polarised when science is uncritically imported into the adversarial forums of interest-based politics, so that environmental science is increasingly unable to support political action. I shall argue that the revolutionary potential of SEA to transform the policy process rests upon a recovery of its original, civic purposes.
My thesis is that a deeper understanding of the relationship between scientific knowledge and political action is required if SEA is to be rigorous, and also relevant to public concerns. Philosophical pragmatism contributes epistemological resources vital to this task. By situating knowledge in the context of practice, and by recognising the dialogical, judgmental nature of rationality, the practical philosophy of pragmatism reclaims the contextually embedded nature of inquiry. When science is embedded in a wider ethical context, the meaning and purposes of environmental knowledge become central questions of policy.
The procedural ethics of both liberal and Habermasian politics cannot address these questions, however, because they relegate questions of the public good to the realm of individual choice. Instead, I argue that public dialogue, guided by a praxisoriented virtue ethics, is required to recover objective environmental goods in the policy process. I also argue that Aristotlean rhetoric, with its focus on the credibility of expertise, is the mode of persuasive argument most appropriate for dialogical public forums. The public philosophy of civic environmental pragmatism is therefore presented as a richer theoretical framework for understanding the contribution of both experts and citizens in the development of environmental knowledge for policy. As a dialogical framework for SEA, civic environmental pragmatism constructively combines the critical/normative and instrumental/descriptive aspects of policy inquiry, both of which are required in the development of socially robust knowledge and politically feasible policy decisions.

Full textAbstract:
According to Swedish law municipalities have to assess if detailed development plans may lead to a significant effect on the environment, a screening. In this the- sis we have investigated how municipalities present their assessment in the de- tailed development plan brief. We have examined all plans that came into legal force in 2012 in the county of Stockholm 259 plans in total. Of all the plans, 223 include a screening in the detailed development plan brief. We have studied the municipalities explanations, why they make a screening on detailed development plans, if the municipalities provide a statement whether a significant environmental impact may occur or not, and if the municipalities justi- fied their statement. Furthermore, we have studied whether municipalities state that consultations have taken place and if they refers to environment-related doc- uments in their screening. We also have classified the explanation and the justifi- cations as clear or unclear. Finally, we investigated what impact the acreage of the plan has on the screening. Almost all plans with a screening in the detailed development plan brief make statement. About a quarter of the plans making a statement lacks justifications. For more than half of the plans with statement and justification, the justification is unclear. We have observed that plans prepared in a simplified way have poorer screenings. Furthermore, the result implies that the quality of screenings is higher for plans concerning national interest and/or shore protection and for plans primarily con- cerning green land. We can see that the number of plans that may lead to signifi- cant environmental effects increases with larger plan areas, as does the amount of clear justifications. Out of all plans, only 3.5 percent was considered being able to cause such a significant effect on the environment that an environmental impact assessment was conducted. Finally, we suggest a law enforcement that the screenings must be presented in the detailed development plan brief. Additionally, we think that the legislation con- cerning screenings has to be clearer, simpler and more specific.Vi tycker slutligen att det ska lagstadgas att kommuners bedömning av detaljpla- ners miljöpåverkan ska redovisas i planbeskrivningen. Vidare anser vi att lagtex- ten på området måste förtydligas, bli mer specifik och förenklas. Enligt gällande rätt ska kommuner göra en bedömning av om planer kan medföra betydande miljöpåverkan, en så kallad behovsbedömning. I detta examensarbete har undersökts hur kommuner redovisar sin bedömning i planbeskrivningen. Samtliga detaljplaner som vann laga kraft år 2012 i Stockholms län studerats, to- talt 259 planer. Av samtliga planer har 223 stycken en behovsbedömning i plan- beskrivningen. Vi har studerat om kommunerna förklarar varför de behovsbedömer detaljplaner, om kommunerna gjort ett ställningstagande till om en betydande miljöpåverkan kan uppkomma och om kommunerna motiverat sina ställningstaganden med skäl. Vidare har studerats om kommunerna redovisat att samråd enligt förordningen om miljökonsekvensbeskrivningar ägt rum och om kommunerna hänvisar till miljöre- laterade dokument i bedömningen. Vi har även klassat förklaringen och skälen som tydliga respektive otydliga. Därtill har vi studerat hur planområdenas storlek påverkar behovsbedömningen. Nästan alla planer med en behovsbedömning i planbeskrivningen har ett ställ- ningstagande. Cirka en fjärdedel av planerna med ställningstagande saknar skäl och mer än hälften av planerna med skäl har otydliga skäl. Vi har observerat att planer som upprättas med enkelt planförfarande har behovs- bedömningar av lägre kvalité. Vidare talar resultatet för att kommunerna genom- för behovsbedömningarna bättre när planer berör riksintresse och/eller strand- skydd samt när planer främst avser grönmark. Vi kan se en ökning av antal miljö- bedömningar och andelen tydliga skäl ju större planareorna blir. Av samtliga pla- ner ansågs endast 3,5 procent kunna medföra en betydande miljöpåverkan.

Bibliography: p. 94-95.The purpose of this report is to: * assess the biophysical and socio-economic impacts of closure of De Beers Namaqualand Mines (DBNM) * provide preliminary suggestions for mitigation measures. DBNM anticipate that they will close in approximately 10 years' time. By the year 2002, all diamond deposits which are currently economically viable to mine on a large-scale would have been exploited. Closure is anticipated to have a significant impact on DBNM employees, their households, and towns where the households of employees live. Furthermore, closure is anticipated to have a significant impact on the Namaqualand economy. Therefore, DBNM commissioned the EEU to undertake an assessment of the impacts resulting from mine closure, to ascertain the effects on their employers and their affected households and communities. Through discussions with DBNM the scope for this assessment was established: * Briefly to describe the current biophysical, social and economic environments in Namaqualand and identify different trends in the region. * To assess in detail the socio-economic impacts resulting from the closure of DBNM. In addition, this report considers the impacts on the biophysical environment resulting from the closure of DBNM, because the socio-economic well-being of employees from rural areas of Namaqualand and Transkei is intrinsically linked to changes in the biophysical environment. Lastly, this report also contains preliminary suggestions for mitigating the impacts of closure.

Full textAbstract:
In the United States, biodiversity impact assessment has historically received little attention. Responding in 1993, the Council on Environmental Quality (CEQ) released guidelines on incorporating biodiversity into environmental impact assessment under the National Environmental Policy Act of 1969. The objectives of the study here were to identify the level of documentation of biodiversity impact assessment in sample Environmental Impact Statements (EISs); identify whether in the years following the
release of 1993 CEQ guidelines any significant changes have taken place in assessment of biodiversity; identify deficiencies, and if the need exists, formulate appropriate recommendations and approaches for addressing biodiversity in EISs. The study involved a systematic review of 30 EISs published since the release of CEQ guidelines, and five EISs published prior to it. The review involved answering a series of standard questions, which attempted to ascertain the level of biodiversity impacts included in each
impact statement. Trends in approaches to biodiversity impact assessment were investigated and deficiencies summarized. The analysis resulted in a series of recommendations for improving the manner in which biodiversity impact assessment can be approached.

The importance of preserving the Amazonian biome given its ecological relevance to the planet does not prevent the concentration of energy projects in the Amazon region due to its unique hydro potential. The hydrographic basins of the Amazon River, which includes the Teles Pires River and the Tocantins River, account for about 80% of the new hydroelectric plants planned to meet the demands of electricity in Brazil according to planning documents. The debate about the significant socio-environmental impacts associated with the advance of the hydroelectric frontier for the Amazon region has been intense. In the country since 2003, the hydroelectric sector, besides having their projects evaluated by the Environmental Impact Studies (EIS), also began to be discussed in the context of watersheds through the Integrated Environmental Assessment (IEA). Given the socio-environmental vulnerability of the Amazon region to the construction and operation of hydroelectric plants, it is relevant to discuss the cumulative impacts resulting from multiple hydroelectric plants in the same basin. The objective of this research is to study the environmental studies carried out in the Teles Pires river basin and three hydroelectric projects in this basin, respectively, the Teles Pires river basin IEA and the Colider Hydroelectric plant EIS, the Teles Pires Hydroelectric plant and the Sinop Hydroelectric plant. Thus, it is established as a research question: How the cumulative impacts of hydroelectric projects inserted in a hydrographic basin in the Amazon region are being analyzed in the environmental planning instruments through the Integrated Environmental Assessment and Environmental Impact Study? The general objective of the research is to analyze the evaluation of cumulative impacts from the Teles Pires river basin scale in the Amazon region to the hydroelectric scale by environmental impact assessment instruments applied to the environmental planning of hydroelectric dams. The results of the research show that there is an association between the cumulative impacts presented in the Integrated Environmental Assessment for the Teles Pires river basin and the Environmental Impact Studies of the uses inserted in this basin. The results also point out that the good practices of Cumulative Impact Assessment are present mainly at the river basin level. It is considered that the cumulative impacts of hydroelectric projects inserted in a hydrographic basin in the Amazon region are being analyzed in the environmental planning instruments, mainly through the Integrated Environmental Assessment of the basin and, to a lesser extent, through the Environmental Impact Study of Hydroelectric use.
A importância da preservação do bioma Amazônico dado sua relevância ecológica para o planeta não impede a concentração de projetos de energia na Amazônia motivados pelo seu singular potencial hídrico. As bacias hidrográficas do rio Amazonas, que abrange a do rio Teles Pires, e do rio Tocantins concentram cerca de 80% das novas usinas hidrelétricas previstas para atender as demandas de energia elétrica no Brasil segundo documentos do planejamento. O debate sobre os significativos impactos socioambientais associados ao avanço da fronteira hidrelétrica para a região amazônica tem sido intenso. No país, desde 2003, o setor hidrelétrico além de ter seus empreendimentos avaliados pelos Estudos de Impactos Ambiental (EIA) também passaram a ser discutidos no contexto de bacias hidrográficas por meio da Avaliação Ambiental Integrada (AAI). Dada a vulnerabilidade socioambiental da região amazônica frente à construção e operação das usinas hidrelétricas, torna-se relevante discutir os impactos cumulativos resultantes de múltiplos aproveitamentos hidrelétricos em uma mesma bacia. O objeto da pesquisa refere-se aos estudos ambientais realizados na bacia do rio Teles Pires e em seis aproveitamentos hidrelétricos nesta bacia, respectivamente, a AAI da bacia do rio Teles Pires e os EIAs da UHE Colider, da UHE Teles Pires, da UHE Sinop, da UHE Foz do Apiacás, da UHE São Manoel e da UHE Magessi. Assim, estabelece-se como questão de pesquisa: Como os impactos cumulativos de aproveitamentos hidrelétricos inseridos em bacia hidrográfica na região amazônica estão sendo analisados nos instrumentos de planejamento ambiental por meio da Avaliação Ambiental Integrada e Estudo de Impacto Ambiental? O objetivo geral da pesquisa refere-se a analisar a avaliação de impactos cumulativos desde a escala de bacia do rio Teles Pires na região amazônica até a escala de hidrelétricas por meio dos instrumentos de avaliação de impacto ambiental aplicados ao planejamento ambiental de hidrelétricas. Os resultados da pesquisa mostram que há associação entre os impactos cumulativos apresentados na Avaliação Ambiental Integrada para a bacia hidrográfica do rio Teles Pires e os Estudos de Impacto Ambiental dos aproveitamentos inseridos nesta bacia. Os resultados apontam ainda que as boas práticas de Avaliação de Impactos Cumulativos estão presentes sobretudo no nível de bacia hidrográfica. Considera-se que os impactos cumulativos de aproveitamentos hidrelétricos inseridos em bacia hidrográfica na região amazônica vêm sendo analisados nos instrumentos de planejamento ambiental, principalmente, por meio da Avaliação Ambiental Integrada da bacia e, em menor proporção, por meio do Estudo de Impacto Ambiental do aproveitamento hidrelétrico.

Full textAbstract:
Activities, conducted in the logistics sector, contribute to pollute the world. Especially, road transportation contaminates the environment with the release of exhaust emissions. Transport volumes as well as the proportion of the road sector are constantly rising, which intensifies its environmental impacts. In order to determine the main culprits of pollution, Environmental Impact Analysis (EIA) are used. These concepts are mostly ambiguous, fuzzy and hard to present in a comprehensive way. The main purpose of the present thesis is to develop an analysis in order to investigate the environmental impacts of road transportation along a certain supply chain. An academic resource was used as database, in order to develop and test an exhauste mission calculation in cooperation with a case company. Besides CO2, this assessment also focuses on the measurement of other exhauste missions like Nox, PM or CO. Furthermore, economic factors like, costs caused per transport are calculated. Aspects, like capacity utilization, the use of environmentally friendly tires or eco-friendly driving styles, are included in the analysis. These factors influence fuel consumption and thus the final production of exhaust emissions. A detailed description of each factor and calculation step is illustrated in this thesis. Due to a high complexity of transportation, this analysis is limited to road transportation. The fundament of the analysis builds the categorization of crafts due to the Euro standards. Hence, just transports conducted with crafts, manufactured within the European Union, can be evaluated. A validation test and in-depth interviews were conducted in order to approve the practicability of the developed assessment. During this process, strengths and weaknesses of the analysis were identified. Finally, the analysis is critically examined by showing its application constraints as well as prospective development opportunities. An enlargement, to include other transport modes, material handling activities in order to measure impacts during intermodal transportation along a whole transportation chain, is a prospect outlook.

The paper identifies three topics in order to evaluate the improvements in the regulation of the National System of EnvironmentalImpact Assessment, looking to benefit the people’s trust in the environmental certification. The first one consists in the gradual transition from the prevention paradigm to the integration one, as the purpose of the different instruments that compose the system; the second involves the enrichment in the evaluation of the Environmental Impact Study (EIS), by incorporating the scoping phase; and the third involves adopting additional measures that reinforce the independence of the teams in charge of the elaboration and evaluation of the EIS.El artículo identifica tres áreas para evaluar mejoras a la regulacióndel Sistema Nacional de Evaluación de Impacto Ambiental, con miras a favorecer la aparición de confianza ciudadana respecto de la certificación ambiental. La primera tiene que ver con transitar gradualmente del paradigma preventivo al integrativo como finalidad de los instrumentos que componen el sistema; la segunda, con enriquecer la evaluación del estudio de impacto ambiental (EIA) incorporándole una etapa de scoping a cargo del Estado; y la tercera, con adoptar medidas adicionales que refuercen la independencia de los equipos de elaboración y evaluación del EIA.

Full textAbstract:
This thesis will investigate the possibility of leasing as a 'greener' form of business transaction. With leasing, the customer pays for the service obtained form the product, but does not own the physical asset; ownership remains with the lessor. This has been claimed to increase resource productivity and close material loops. Numerous complications exist, however, such as tax regulations limiting operating leases to terms of 75% of the total product's life. In addition, no clear pattern has emerged in leasing practices, and in most cases manufacturers approach leasing on an ad hoc basis. Research has found that usage-phase impacts play a major role in determining the advantages realized by leasing. Products such as vehicles or refrigerators that continually consume energy negatively impact the environment much more during their use than during manufacturing or transportation. Because most lease agreements contain maintenance contracts, the opportunity to upgrade and increase product efficiency during this use-phase is paramount to reducing negative impacts. Remanufacturing also shows potential to further reduce resource requirements. However, if product efficiency is not improving significantly, remanufacturing alone does not make a significant impact. In some cases, such as carpets, remanufacturing is not practical, but recycling can be utilized. However, tax regulations require leased terms to be less than that of a product's designed life, hastening replacement. This has the potential to offset any advantages seen with a lease agreement. Academic work in this area remains very limited and product-specific. Case study analyses performed in this thesis found that increased product turnover can actually be environmentally beneficial when product technology is improving. These gains can be further improved with remanufacturing and optimized product replacement moderated by lease agreements. If usage energy is significantly less than manufacturing energy, leasing has little value for reducing impacts. Also leasing may motivate closed material loops, without improving product efficiencies there is no advantage to optimizing life cycles with lease contracts.

A formação do reservatório de Itaipu propiciou a colonização para o curso superior do rio Paraná de mais de 15 espécies de peixes, incluindo as arraias do gênero Potamotrygon, as quais já se estabeleceram na área do alto rio Paraná, com ocorrências comprovadas nos reservatórios de Porto Primavera e Jupiá, nos rios Paranapanema, Sucuriú e baixo Tietê. A região de estudo apresenta atividades diretamente ligadas ao rio, como prática de esportes náuticos, pesca e formação de balneários. Assim, sua ocorrência pode configurar uma preocupação para a população local. Em entrevistas realizadas, percebe-se como esse animal está conseguindo se dispersar e estabelecer no ambiente. Esta dissertação teve como objetivos: conhecer os impactos que esses animais causam à região do alto curso do rio Paraná e alguns de seus afluentes, estimar o conhecimento da população ribeirinha e demais freqüentadores dos locais em relação às arraias, pesquisar sobre a utilização destes animais para fins comerciais e consumo da carne, relatar a ocorrência de acidentes e obter informações sobre estórias, mitos e dúvidas a respeito do animal em estudo. As comunidades tradicionais têm conhecimentos sobre as arraias, ao contrário dos demais frequentadores dos rios, sendo estas, consideradas animais perigosos por ambos. Entre as conclusões, verificouse a falta de medidas que protejam os balneários e praias da região contra acidentes. A carne de arraia não tem valor comercial algum, assim como as pessoas da região não têm o costume de consumir este tipo de alimento. As estórias locais geram mais temor, discriminação e repulsa ao animal. É necessário um trabalho de educação ambiental que faça com que as pessoas reflitam sobre a questão do aparecimento desses animais, pois isto ajudaria a diminuir o temor e preconceito que existe com as arraias de água doce
The formation of the Itaipu reservoir gave way to the colonization of the upper part of the Paraná river for more than 15 species of fish, including the freshwater stingray of the genus Potamotrygon, which had already established in the high area of the river Paraná, with occurrences proved in the reservoirs of Porto Primavera and Jupiá powerplants, in the Paranapanema, Sucuriú e low Tietê rivers. The region of study presents activities directly related to the river, such as the practice of nautical sports, fishing and formation of bathing places. So, its occurrence may be a concern for local people. In interviews, it was noticed how the animal is able to disperse and establish in the environment. This dissertation aimed to: know the impacts that these animals cause in the region of the upper course of the Paraná river and some of its tributaries, measure the knowledge of the riverside population and other regular visitors of the place about the freshwater stingray, research the use of these animals for trade and consume of meat, report the occurrence of accidents and information on the stories, myths and doubts about the animal studied. The traditional communities have knowledge about the freshwater stingray, otherwise the regular visitors of the rivers do not have it, but the animals are considered dangerous by both groups. Among the conclusions, there was the lack of measures to protect the region's bathing places and beaches from accidents. The meat of freshwater stingray is not a commercial, and the people of the region haven’t the habit of consuming such food. The local stories generate more fear, discrimination and rejection for the animal. It is necessary a work in environmental education capable to make people reflect on the question of the appearance of these animals, as this would help reduce the fear and prejudice that the freshwater stingray can cause

We investigate how the requirement that organic chemistry be possible constrains the values of the quark masses. Specifically, we choose a slice through the parameter space of the Standard Model in which quark masses vary so that as many as three quarks play a role in the formation of nuclei, while keeping fixed the average mass of the two lightest baryons (in units of the electron mass) and the strength of the low-energy nuclear interaction. We classify universes on that slice as congenial if they contain stable nuclei with electric charge 1 and 6 (thus making organic chemistry possible in principle). Universes that lack one or both such stable nuclei are classified as uncongenial. We reassess the relationship between baryon masses and quark masses, using information in baryon mass differences in our world and the pion-nucleon sigma term [sigma]IIN. We generalize the Weizsacker semi-empirical mass formula through a degenerate Fermi gas model that handles the kinetic energy of new baryonic species as they begin to participate in the nucleus, and derive an expression for the asymmetry energy equivalent in the SU(3) limit through a minimization procedure on the quadratic Casimir operator. We spell out the conditions for decay by weak nucleon emission. Finally, we study the congeniality of various regions in the quark mass space, primarily by direct comparison to analog nuclei in our universe. Considering only two light quarks u and d, we find a band of congeniality roughly 29 MeV wide in mu - md, with our universe living comfortably away from the edge. We find multiple congeniality regions in the three quark mass space. For an important region around the SU(3) limit, we have not determined conclusive results but we have constructed the machinery to aid in its analysis and formulated the relevant problems. We have succeeded in formulating a well defined question about congeniality, and have made concrete progress toward answering it.

This thesis was intended to investigate the environmental impact of grinding in the United States manufacturing industry. Grinding is an ideal method for producing parts with a fine surface finish and high dimensional accuracy and for shaping hard or brittle workpieces. There are a wide variety of different types of grinding machines, each with different applications and slightly different energy requirements. Workpieces are generally flooded with a stream of coolant while being ground or placed in a spray of coolant mist. Coolant recycling systems are used to filter ground off chips out of coolant and to remove foreign oils and bacteria which pose health hazards. Oil mist collectors both clean mist coolant and prevent the toxic coolant from being inhaled by machinists. In total, 63 *10¹⁵ joules of energy are consumed per year by grinding in manufacturing, 57% of which is directly used in material removal. A total of 1.5*10¹⁰ pounds of scrap chips, spent grinding wheels, and used filters are produced each year as a result of grinding, over 99% of that being scrap chips. About 2.3 million gallons of fluids per year of grinding fluids are incinerated. Grinding creates a significant environmental footprint, creating a need for methods to reduce energy use in grinding and for ways to recycle solid waste that would otherwise be sent to landfills or incinerated.

Full textAbstract:
The aquatic macrophyte Crassula helmsii is a non-native species and classed as 'invasive' in the UK. This study was carried out in an attempt to provide empirical evidence as to whether the establishment and growth of Crassula helmsii has a measurable impact on the ecology of invaded sites. Dispersal and distribution patterns across England were explored using databases and GIS interpretation. Ecological impact was measured by comparing invaded sites with uninvaded control sites on a range of habitats and waterbody types across Kent and East Sussex. The analysis of spread patterns provided evidence that the plant is likely to have been dispersed due to the horticultural trade, as well as natural vectors into neighbouring habitats. Macrophyte analysis showed that species losses did not occur when C. helmsii was present. Changes to species composition did occur, with rarer plant species being associated with the presence of C. helmsii. Freshwater macroinvertebrates showed no change in either species number or species rarity. The seed banks of invaded and control sites showed no difference, but active management was shown to reduce the total number of seeds in the soil significantly. The water chemistry of invaded and uninvaded sites showed a relationship between the presence of C. helmsii and reduced total organic nitrogen. The results of this study show that the expected species loss associated with non-native species may not be occurring with C. helmsii. Active management may be impacting the ability of native species to recolonise. Further work on other habitats and waterbodies across a wider geographic range are required to explore whether this is a localised effect.

Full textAbstract:
Aquaculture has great potential to help supply the nutritional needs of a growing population. To date, however, the benefits that aquaculture can have, have largely been overshadowed by the environmental degradation some segments of the industry have caused. The following body of work describes my efforts to help reduce the environmental impacts of aquaculture. By integrating aquaculture production into traditional agriculture, the impact of farming on already limited water resources and the reliance on chemical fertilizers can be reduced. Recent expansion of the aquaculture industry in Arizona has made it possible to study the integration of olive groves with marine shrimp culture. In chapter 3, I describe the characterization and evaluation of the effluent from an inland, low-salinity shrimp farm as a potential source of irrigation water. I found that 0.41 kg of ammonia-nitrogen, 0.698 kg of nitrite-nitrogen, 8.7 kg of nitrate-nitrogen and 0.93 kg of total phosphorus (TP) were made available as fertilizer each day in the effluent water. Based on the results of this first study, I decided to conduct a farm trial to quantify the effects of these shrimp farm effluents on olive trees. This work is described in chapter 4. Trees in all treatment groups grew an average of 40.1 cm over the four month study period. While growth of trees irrigated with shrimp farm effluent did not improve in respect to the other treatments, our results do indicate that irrigating with low-salinity water had no noticeable negative effects. Chapter 5 describes work conducted in Idaho, as part of a larger study aimed at reducing the effluent loads of phosphorus (P) from high density, flow-through aquaculture facilities. Research steps were taken to establish a relationship between TP and the carbon 12/13 isotope ratio (δ¹³C) and/or the nitrogen 14/15 isotope ratio (δ¹⁵N). Our findings suggest that both δ¹⁵N and δ¹³C are good better proxies for P, after correcting for P retention. A linear regression of %P (corrected) on δ¹³C and δ¹⁵N resulted in R2 values of 0.843 and 0.8622, respectively. This suggests that by tracking δ¹⁵N and/or δ¹³C through a high-density, flow-through aquaculture facility over time I will be able to determine the residence time of P with a high degree of accuracy.

Resumo: O Relatório de Impacto Ambiental (RIMA), por muitas vezes sub-estimados em seu valor, apresenta-se apenas como um capítulo no Estudo de Impacto Ambiental (EIA) sem o devido reconhecimento e grau de relevância. O objetivo do presente estudo foi à proposição de um novo método de avaliação de impactos ambientais, no qual, a caracterização e formatação apresentaram-se direcionadas ao público leigo e distinto dos profissionais que realizam os trabalhos ambientais, porém, de grande relevância em processos licenciatórios. Este estudo teve inicio por via de uma pesquisa bibliográfica detalhada em métodos: de avaliação de impacto ambiental existentes; ensino a adultos e a adolescentes; e, bancos de dados à área de meio ambiente; e finalizou em um método dinâmico de estudo, no qual profissionais de pouco conhecimento no assunto encontram-se embasados, suportados por um programa computacional o qual apresenta seu banco de dados livre com grande e rápida comunicação, acessibilidade e transporte. Os resultados dos estudos de caso demonstraram a facilidade de implantação do método, entretanto, quanto aos questionamentos envolvendo especificamente o tempo de implantação bem como a troca dinâmica informações verificou-se a necessidade de novos levantamentos no assunto, a serem realizados em estudos futuros.
Abstract: The Environmental Impact Report is often a poorly addressed chapter in the Study of Environmental Impact. In most cases, the chapter fails to transmit to the general public the relevance and importance of such report. The objective of this study is to propose a reform in the method of analyzing and reporting environmental impact, making it more comprehensive, clear, and relevant to the general public. The study was carried out with a detailed bibliographic research in the following areas: A) methods of evaluating environmental impact; B) Adolescent and Adult Pedagogy; C) Environmental Studies Database. Later on, a more interactive study was conducted. This study observed a group of professionals, who had limited knowledge in environmental studies, as they interacted in a closed environment equipped with computers connected to various natural sciences databases, containing a strong and reliable system. The study found the proposed method of Environmental Impact Report to be easy to implement. However, more research is needed in order to address specific questions, such as the time of implementation of the new method and the dynamics of the exchange of data.

A Avaliação de Impacto Ambiental é um instrumento que auxilia o processo decisório, a elaboração de projetos e propostas de desenvolvimento, e que oferece campo para a integração de valores associados à sustentabilidade e ao desenvolvimento sustentável. Para que a avaliação de impacto ambiental seja efetiva, deve estar embasada na delimitação das questões prioritárias, bem como em respostas adequadas e necessárias aos tomadores de decisão, em um processo conhecido como scoping. A delimitação do escopo de um Estudo de Impacto Ambiental (EIA) tem como principal objetivo definir os estudos considerados adequados para a correta avaliação dos impactos potencialmente significativos relacionados a um projeto, orientado pelo diagnóstico preliminar de suas áreas de influência. Diante da necessidade de avaliar a efetividade dessa etapa dentro do quadro geral da AIA praticada, o objetivo do trabalho foi avaliar a etapa de delimitação do escopo de estudos de impacto ambiental de processos de Avaliação de Impacto Ambiental ocorridos no Estado de São Paulo, utilizando-se como marco referencial a promulgação da Resolução SMA 54/2004. A fim de estudar o processo de scoping no estado de São Paulo, nos termos da regulamentação vigente e com base nas melhores práticas preconizadas para este instrumento, foram analisados 34 processos de licenciamento ambiental que tramitaram na Secretaria de Meio Ambiente do Estado de São Paulo (SMA/CETESB), para diferentes tipologias de empreendimento. Os resultados obtidos demonstram que a estrutura preconizada para o scoping no estado, ainda que seja potencialmente diferenciada em relação aos demais estados do país, não tem assegurado a formulação de Termos de Referências concisos e focados nos impactos significativos dos empreendimentos, pouco contribuindo para a efetividade das avaliações de impacto.The Environmental Impact Assessment is an instrument which helps in the decision making, the elaboration of projects and development of proposals, also offers a way for the integration of values associated with the sustainability and sustainable development. For the environmental impact assessment to be effective, it should be based on delimitation of priority issues, as well as responses appropriate and necessary to the decision makers, in a process known as scoping. The main objective of the EIA scoping is define the studies considered suitable for the correct evaluation of potentially significant impacts related to a project, directed by the preliminary diagnosis of their areas of influence. Considering the need to evaluate the effectiveness of this step within the overall framework of the EIA carried, the aim of this study was to evaluate de scoping phase in environmental impact statement of Environmental Impact Assessment processes occurred in São Paulo State, under the current regulation and based on best practices recommended for this instrument. The study evaluated 34 environmental licensing process which were proceed through the Secretary of Environment of the São Paulo State (Secretaria de Meio Ambiente do Estado de São Paulo - SMA/CETESB), with different development typologies. The results obtained showed that the structure recommended for the scoping in the São Paulo State, although it is potentially different than the other states in Brazil, it hasnt ensured the elaboration of Terms of Reference concise and focused on significant impacts of the projects, with few contribution to the effectiveness of environmental impact assessment.

Full textAbstract:
This thesis examines environmental impact assessment (EIA) practices and limitations in Malaysia, and assesses the potential for integrating environmental monetary valuation to the EIA process. This thesis has four research objectives: 1) to analyse the application of EIA in Malaysia and to identify the current practices particularly with respect to valuing environmental impacts; 2) to identify appropriate environmental monetary valuation techniques that could be used in EIA; 3) to apply an appropriate environmental monetary valuation technique to Malaysian EIA through a case study; and 4) to provide an initial evaluation of the proposed technique by EIA practitioners. The content analysis of 165 EIA reports indicates a lack of environmental monetary valuation in EIA in Malaysia, and that project costs were poorly presented. In addition, the semi-structured interviews indicate that the quality of EIA in Malaysia depends on the quality and experiences of the EIA consultants. The case study using CV MS technique in EIA indicated that CV MS is an appropriate technique in the Malaysian context. It is concluded that the CV MS technique can facilitate wider public participation in EIA for a balanced and societal decision for economic development and environmental protection. As a result, CV MS can bring together scientific, social, and economic input within EIA reporting. This thesis concludes with recommendation for integrating the CV MS technique to the EIA process in Malaysia, and makes suggestions regarding how the limitations of CV MS in EIA might be overcome to ensure a balance between development needs and Malaysian environmental objectives within the context of the Malaysian people.

Full textAbstract:
Introdução: A Avaliação de Impactos à Saúde (AIS) é adotada em vários países como estratégia para abordar os potenciais impactos à saúde relacionados a políticas, planos, programas ou projetos, mas não é ainda utilizada no Brasil. Objetivo: Identificar as condições brasileiras que podem corroborar com vantagens e limitações da AIS já descritas na literatura internacional, considerando sua aplicação futura no Brasil, especialmente no caso de projetos. Métodos: Revisão da literatura científica e de outros documentos internacionais sobre AIS, identificados através de bases de dados (Pub Med e Science Direct), e de portais especializados, para entender o contexto e compilar vantagens e limitações da AIS. Revisão da literatura científica nacional e de outros documentos sobre avaliação de impactos e saúde, identificados através das bases de dados LILACS, SCIELO e outros portais brasileiros que tratam desses temas. Pesquisa qualitativa complementar com profissionais e pesquisadores brasileiros. Resultados e discussão: A AIS ainda está se desenvolvendo no mundo, por isso há vantagens e limitações igualmente importantes associadas aos seus indutores; ao objeto da avaliação (políticas, planos, programas ou projetos); à fase em que é conduzida (prospectiva ou retrospectiva); aos patrocinadores e avaliadores; ao tipo de AIS adotada; à sua institucionalização; à integração a outras formas de avaliação de impactos (AIA ou AAE); à abordagem em saúde, ao escopo e aos métodos adotados; à participação das partes afetadas e a sua influência no processo de tomada de decisão. No Brasil, os estudos que abordam os impactos à saúde são frequentemente retrospectivos e a abordagem de saúde na AIA apresenta lacunas. Os poucos estudos prospectivos ainda não utilizam as ferramentas e passos da AIS. O Ministério da Saúde vem articulando o processo de introdução da AIS no país. Conclusões e Recomendações: Há oportunidades para introduzir a AIS de projetos no país. Entretanto, é urgente o engajamento dos profissionais brasileiros da área de saúde e de avaliação de impactos com as redes de profissionais nacionais e internacionais, visando aprimorar a discussão e prepará-los para enfrentar questionamentos à AIS eventualmente levantados por aqueles que veem no processo de avaliação de impactos obstáculos para a eficiência e rapidez da tomada de decisão sobre projetos. É também preciso organizar padrões mínimos para que não sejam reproduzidos no Brasil problemas já vivenciados e solucionados em outras localidadesIntroduction: Health Impact Assessment (HIA) is adopted as a strategy to address the potential health impacts associated with policies, plans, programs or projects in various countries, but not yet in Brazil. Objective: To identify the Brazilian conditions that can contribute to HIA advantages and constraints already described in the literature, considering its future adoption in Brazil, particularly in the case of projects. Method: Review of scientific literature and other documents on HIA, identified in Pub Med and Science Direct, as well as in HIA websites, in order to understand the context and compile HIA advantages and constraints already described in the literature. Review of Brazilian scientific literature and other Brazilian documents on impact assessment and health, identified through LILACS and SCIELO databases as well as other Brazilian web sites that address the subject. Additional qualitative research with Brazilian stakeholders. Results and discussion: HIA is still developing worldwide. Due to that, there are equally important advantages and limitations associated to its drivers, its object (policies, plans, programs or projects), when it is conducted (prospective or retrospective), HIA sponsors and assessors, HIA types, if HIA is institutionalized, if it is integrated with other forms of impact assessment (AIA, SEA), its approach to health, its scope and methods, the participation of affected parties and its influence to decision making. In Brazil, health impact assessments are frequently retrospective and do not adopt HIA tools and its steps. The Brazilian Ministry of Health is working to introduce HIA in the country. Conclusions and recommendations: There are opportunities to introduce HIA of projects in the country. However, it is urgent to engage Brazilian health and impact assessment professionals with national and international networks, in order to deepen and improve the discussion and to prepare them to face future questioning to HIA eventually raised by those that view the impact assessment process as an obstacle to efficiency in the context of project decision making. It is also necessary to develop minimum standards so that some issues already faced and solved elsewhere are not repeated in Brazil

Society needs information and communication technology (ICT) hardware to produce, process and store highly valuable information. This hardware, of course, affects the environment throughout its whole life cycle, starting with manufacturing, where the necessary scarce and precious resources (e.g. rare earth metals) are often mined under miserable environmental conditions. This leads to pollution of soil, water and air in the present as well as for the future. During the use phase of ICT hardware, energy consumption impacts the environment. At the end of life of ICT hardware, recycling, disposing as e-waste in landfills or disassembling are additional impacts that affect the environment. More and more producers and users, especially companies, want to measure these impacts, which is a complex task. However, approaches to measure the impacts are at hand, either as single indicators, measuring one specific impact, or as composed indicators, combining different single indicators into one "summarizing" indicator. However, collection of data, measurement, assessment and interpretation are challenging. Unfortunately, guidelines for those who want to measure the impact of ICT hardware are rare. With our research, we aim to shed light on the various approaches to measure impacts of ICT hardware as well as their application in practice. Based on a literature review, we identified different indicators and them to the attention of experts from companies to assess these approaches in terms of practicability, significance and value for practice. The results show that research investigates and proposes a variety of different more or less complex indicators. However, business prefers single indicators, which are easy to measure and understand.

In the first part of the article, a theoretical and doctrinal development of the concept of environmental impact and its positive and negative side is proposed. Further, a comparison and theoretical differentiation between the environmental impact and environmental pollution is developed.In the second part of the article, the theoretical concepts are reflected on a practical level, developing the implications of negative environmental impact before, during and after the implementation of productive activities.En la primera parte del artículo se propone un desarrollo teórico – doctrinario del concepto de impacto ambiental y de su vertiente positiva y negativa. Asimismo, se desarrolla una comparación y diferenciación teórica del concepto impacto de ambiental negativo y de contaminación ambiental. En la segunda parte, se plasman los conceptos teóricos a nivel práctico, desarrollando así las implicancias de los impactos ambientales negativos antes,durante y después de la ejecución de actividades productivas.

Mestrado em Engenharia do Ambiente / Instituto Superior de AgronomiaEach European Union state member performs analysis on certain projects possible impacts on the environment through the instrument of Environmental Impact Assessment. This procedure has been implemented on each member state level, being altered and improved e several occasions, finding itself under constant evolution. The content of that assessment verified in the correspondent documents of the EIA, specifically in the Environmental Impact Statement, appear to be somewhat subjective, being that the description of the affected environmental resources by the project implementation under that procedure is presented with a certain level of abstraction. This work looks forward to present ways to enhance the objectivity and consequently the clearness of those Environmental Impact Assessments, focusing mainly on demonstrate the valuation the environmental resources affected by the Environmental Impact Assessment project, allowing a better comprehension by the stakeholders about the real value of the pre-existent resources in the area of the project. The great problematic directly linked to the resources valuation is centred in the easy monetary value attribution whenever a resources has a market price counter pointing the remaining non-marketed resources. Such approach involves the adoption of a classification system of ecosystem goods and services, particularly in this case the Common International Classification of Ecosystem Services that comprises the environmental resources considered in the Environmental Impact Assessments Finally the application of the Common International Classification of Ecosystem Services approach integrated in the Environmental Impact Assessment is demonstrated and the valuation of the environmental resources is performed through the benefit transfer method serving as example for the potentiality of this procedure
