O presente Trabalho de Tese objetiva a concepção e o desenvolvimento de um sistema estrutural treliçado modular em madeira. Avalia o comportamento de alguns dos seus principais elementos constituintes, através de experimentos realizados em laboratório e apresenta provas com programas funcionais, tornando factível a implantação do artefato arquitetônico em terrenos difíceis com mínimo impacto ambiental. Compara de forma estimativa os custos dessa estrutura executada em madeira, concreto e aço. É permeado em sua primeira fase por um breve relato da Arquitetura Brasileira em madeira, do colonial ao contemporâneo e pela descrição sucinta das características da madeira, privilegiando sua capacidade portante e finalmente pela concepção e desenvolvimento do sistema estrutural em madeira, objeto desse trabalho, denominado Sistema estrutural treliçado modular em madeira SET 2M. Em sua segunda parte, procura-se dotar o sistema com provas de programas funcionais: três residências unifamiliares, uma multifamiliar e uma pousada. O sistema baliza-se no princípio que, para se pensar e construir uma edificação de boa qualidade com baixo custo de construção, deve-se introduzir altos níveis de racionalidade e criatividade na concepção do espaço e na sua construção. O SET 2M é caracterizado pela aplicação metodológica da sucessão e continuidade de eventos, assim como da coerência de decisões, em função de suas racionalidades de concepção e de construção, as quais objetivam organizar e prever diferentes operações em oficinas de marcenaria e serralharia em suas montagens no canteiro de obras. Essas montagens processam-se através da utilização de: 1) recursos simples, exigindo equipamentos e ferramentais disponibilizados correntemente no mercado na construção civil; 2) equipe composta por um número reduzido de pessoal; 3) prazo de execução exíguo, devido às suas características projetuais de concepção e de construção. A madeira se apresenta como um material atraente para essas concepções, pois equipara-se, em termos de custos, ao aço, material altamente empregado nos dias atuais e supera em muito o concreto protendido, material possível de execução quando pensado com as características específicas do SET 2M. Para a concepção e o desenvolvimento do SET 2M realizouse, no laboratório do LAME da FAUUSP, maquetes e protótipos de alguns dos mais significativos de seus elementos constituintes, que atestaram de forma bastante satisfatória o comportamento do sistema. A estrutura foi calculada no nível de desenvolvimento inicial, possibilitando, assim, sua estabilização geral. / The present Thesis aims the conception and the development of a wooden modulated latticed structural system. This work evaluates the behavior of some of its main constituent elements, through experiments carried through in laboratory, and presents tests with functional programs, becoming feasible the implantation of the architectural device in difficult lands with minimum environmental impact. It compares and esteems the costs of this structure executed in wood, concrete and steel. It is composed in its first phase by a brief story of the Brazilian Architecture in wood, from the colonial to the contemporary, a quick description of the characteristics of the wood, privileging its carrying capacity, and finally by the conception and development of the wooden structural system, the object of this work, called Wooden modulated latticed structural system SET 2M. In its second part, it looks to endow the system with tests in functional programs: three single residences, one familiar residence and a resort inn. The system is based in this principle: to think and to construct a building of good quality with low cost of construction, we must introduce high levels of rationality and creativity in the conception of the space and its construction. The SET 2M is characterized by a methodological application of the succession and continuity of events, as well as of the coherence of decisions, in function of its rationalities of conception and construction, which aim to organize and to foresee different operations in joineries, carpentries and locksmiths in its assemblies in the building. These assemblies are processed by the use of: 1) simple resources, demanding equipment and tools currently available in the market in the civil construction; 2) team composed by a reduced number of staff; 3) short stated period, due to its projected characteristics of conception and construction. Wood presents itself as an attractive material for these conceptions, because it compares in cost to the steel, highly used nowadays, and it surpasses the extended concrete, a possible material of execution when thought with the specific characteristics of SET 2M. For the conception and the development of the SET 2M, we built in the laboratory of the LAME of the FAUUSP mockups and prototypes of its expressive constituent elements, which certified satisfactorily the behavior of the system. The structure was calculated in the level of initial development, making possible, thus, its general stabilization.

O objetivo desta pesquisa foi estudar a influência da utilização deste resíduo nas propriedades tecnológicas de diversos concretos, determinando assim a sua viabilidade técnica como um agregado alternativo aos agregados convencionais. A metodologia para fabricação dos concretos, bem como para a determinação de todas as propriedades foi de acordo com as Normas da ABNT (Associação Brasileira de Normas Técnicas). Os resultados mostraram que as resistências obtidas tiveram apenas ligeiras alterações, para mais ou para menos, quando comparadas às resistências dos concretos com agregados convencionais. As menores alterações foram observadas para as composições contendo menores consumos de cimento por m3 de concreto, as quais foram também consideradas as mais eficientes. Concluiu-se que o concreto com agregados de pedra mineira é tecnicamente viável, inclusive para estruturas e seu uso pode trazer para a comunidade local uma solução para um problema de impacto ambiental de potencial significativo / Abstract: The quarrying of a flagstone known as ¿pedra mineira¿ at the Southwest of the Minas Gerais State has caused serious environmental issues since this extractive activity has as characteristics a expressive volume of debris. This may reach eighty per cent of the total volume of the stones quarried. The goal of this research is to verify the influence of this quarrying material on the mechanical properties when it is utilized as coarse aggregate in concrete and to determinate whether its employment is technically and economically practicable. The methods used to produce the concrete studied and to carry out the tests were those of the Brazilian Standards (Associação Brasileira de Normas Técnicas). The tests showed that the resistances of the new concrete presented little variation when compared with those of the concrete made with conventional coarse aggregates. The smallest variations were observed for the mixtures containing the smallest content of cement per cubic meter of concrete, being these mixtures considered the most efficient. One concludes that concrete made with the alternative aggregate is technically practicable for structural building and its massive utilization may contribute to a partial solution for the mentioned environmental problem / Mestrado / Edificações / Mestre em Engenharia Civil

The mining industry has been associated with environmental pollution throughout the ages. Old abandoned mines are of particular concern due to the lack of remediation and monitoring of the pollution. The abandoned Edendale Lead Mine in Tshwane, South Africa, was in operation from the 1980’s until 1938 and mined primarily galena for the lead content, although some silver was also recovered in the early years. The mine was decommissioned before environmental legislation in South Africa, namely the National Environmental Management Act 107 of 1998 and the Minerals and Petroleum Resources Development Act 28 of 2002, required the mitigation of environmental impacts associated with mining. Consequently, the environmental effects of Edendale Lead Mine have not been determined. This study is aimed at establishing the source, extent and magnitude of environmental pollution associated with metal contamination from mining operations in the area. Such investigation is of particular interest as there are two schools in the area, namely the Edendale Primary and High School, and the mine site is located immediately adjacent to the Edendalespruit. Furthermore, there are numerous farms and some private residences in the area that rely on borehole water that may potentially be polluted. The ore at Edendale Lead Mine was mined from a hydrothermal deposit, with irregularly disseminated argentiferous galena being the only ore mineral of importance. Two mineralisation stages can be recognised from material available on waste rock dumps, i.e. an intensely fragmented and strongly silicified breccia and a carbonate-dominated breccia with minor pyrite. The galena is restricted to the first mineralisation stage. Water and solid samples were collected from the mine site and from the surrounding area. Through ion chromatography, Inductively Coupled Plasma - Optical Emission Spectrometry (ICP-OES) and Inductively Coupled Plasma - Mass Spectrometry (ICP-MS) analysis, the water of the area is found to be of good quality according to the South African Department of Water Affairs and Forestry Domestic Water Guidelines. The main concern is the presence of hazardous concentrations of lead in the Edendalespruit below the old plant site and in a pit near shaft one; determined to be from the abundance of relatively soluble anglesite (PbSO4) and susannite/leadhillite (Pb4(SO4)(CO3)2(OH)2) in the slag heap and the waste rock dump. Solid samples were mineralogically and chemically analysed using X-Ray Powder Diffraction (XRD) and X-Ray Fluorescence Spectrometry (XRF), which determined the soil to be enriched in lead, zinc, and copper. The lead, zinc and copper are from secondary minerals of galena, sphalerite and chalcopyrite, respectively. Metal mobility and availability was found to be limited through high soil pH conditions, which encourage metal-carbonate precipitation reactions and absorption by iron oxides and hydroxides. However, the high concentrations of lead in the soil are of considerable concern due to its toxicity and the number of people at risk, namely at the Edendale Primary and High Schools as well as users of the Edendalespruit and local ground water sources. The soil lead levels exceed the European Union target and intervention standards, therefore, requiring immediate mitigation and remediation measures. Recommendations for remediation and prevention measures may include the removal of the slag heap at the old mine site and the use of phytoremediation. / Prof. J.M. Huizenga Prof. J. Gutzmer Mr. H.

M.Sc. (Geography) / Over the last three years, a number of environmental impact assessment reports (EIARs) pertaining to renewable energy (RE) projects have been submitted for environmental authorisation in South Africa. However, the quality of EIARs have been criticised internationally as well as in South Africa. Poor quality EIARs has the potential to negatively impact environmental decision-making processes and therefore it is vital to provide baseline data regarding the appraisal of such EIARs in South Africa. The present study has evaluated the quality of basic assessment reports (BARs) dealing with RE projects in South Africa. This is crucial in providing key insights to environmental management practice, especially if we are to determine whether or not RE projects have the potential to achieve sustainable development goals linked to clean development mechanisms (CDMs). Apart from assessing quality aspects, the goal of the study was also to analyse the strengths and weaknesses inherent in the EIARs involved. To address the research problem adequately, the Lee-Colley Review Package was utilised with minor adaptations where feasible. Based on the analyses derived from the review package selected, the overall quality of EIARs was found to be 70% satisfactory whilst 80% of the overall scores were borderline quality grades. The review areas pertaining to the description of the development and environment, together with the identification and evaluation of impacts, were better performed than the review areas concerning alternatives, mitigation measures and communication aspects of the EIARs. The strengths of the EIA processes related to the description of the project (purpose, objectives and nature) and site descriptions. Weaknesses of EIARs pertaining to RE projects were identified as insufficient non-technical summaries and poor summaries of the main issues. The review categories pertaining to waste management, mitigation measures and emphasis were not graded as weaknesses of the EIARs. Nevertheless, low numbers of satisfactory quality scores were documented for these review categories, which are particularly concerning. The fairly marginal quality of EIARs pertaining to RE projects may be attributed to lack of sufficient (human resources) capacity and transparency throughout the EIA process in South Africa. These aspects became evident through vague descriptions of impact prediction methods, insufficient elucidation of mitigation measures, a high degree of subjectivity and generally poor communication of EIA results to stakeholders involved. Apart from these findings, the study also made some recommendations for further studies such as the need to examine the following EIA aspects, namely, (1) the characterisation and reduction of elements of subjectivity within existing reports, (2) an assessment of the effectiveness of screening processes in South Africa and (3) the identification of obstacles and barriers hindering effective communication in the presentation of EIA results.

Does the lead industry have a future, in the face of the developing environmental challenge? This thesis addresses this question and concludes, it should have for the foreseeable future, providing it adopts the changes detailed. These changes are posited within a framework, which consists of a strategy, approaches and tools. The changes are both technical and philosophical. They are technical, in the sense that the tools and approaches provide practical means whereby the environmental `risks' may be identified, assessed and managed. They are philosophical, because they set out and identify the features of a new conceptual paradigm, whose basis is in the concept of the `risk society'. The paradigm is significantly more holistic, multi-dimensional, inherently flexible, and is intended to be reflexive. Adoption of the elements of the framework, will facilitate a more effective establishment, and management of environmental `risk' credentials, which will help encourage better environmental decision making. Hence, it will facilitate, the balancing of resource consumption and environmental impact costs, versus social and economic benefits, in an improved manner. The modelling approaches, and selected inventory and environmental impact assessment tools, enclosed within this thesis, have been designed to facilitate the development of, and to function within, the new paradigm. These have been developed for BRM and MIM case studies, and function at the site-specific and the cradle-to-gate scales. The former consider the company site of Britannia Refined Metals (BRM) Ltd., where refining to produce primary and secondary refined lead products takes place, whilst the latter consider the life-cycle of the refined primary lead products of MIM Ltd. The modelling approaches have also been designed so, that they may be re-aggregated into models able to operate at many different scales, as required. The framework, and its elements, are applicable for all industries facing similar challenges.

Under den senaste tiden har man tagit upp plastbärkassars negativa miljöpåverkan, i EU men även lokalt i Borås. EU anser att plastpåsar är skadliga för miljön och har tagit fram direktiv som gör att alla medlemsstater måste vidta åtgärder för att begränsa förbrukningen av plastpåsar. För att man ska kunna fatta rätt beslut krävs det att man ökar kunskapen om vilka åtgärder som krävs och vilka åtgärder som är mest effektiva för att minska förbrukningen.I detta examensarbete är syftet att jämföra plastpåsars miljöpåverkan mot bärkassar i olika material samt att se över hur plastpåsar hanteras idag, presentera en metod för att utföra en insamling av plastpåsar för återvinning i Borås och utreda om det är miljömässigt lönsamt. Resultaten visar att bestämandet av en bärkasses miljöpåverkan är en mycket komplex fråga då väldigt många faktorer måste vägas in. Vi ser även att införandet av ett separat återvinningssystem för plastpåsar inte är det ultimata då det skulle försvåra logistiken samt kräva komprimering av plastpåsarna för att minska deras volym. Det befintliga återvinningssystemet för plast där man blandar hårdplast och mjukplast är mera lämpligt att använda då det ger en tätare blandning. / The negative environmental impact of plastic bags has recently been brought up in the EU but also locally in Borås. The EU considers that plastic bags are hurtful for the environment and has developed directive to reduce the consumption of plastic bags which all member states must follow. In order to be able to make the correct decisions it is necessary to have the accurate information of what measures are necessary to reduce consumption. In this thesis, the aim is to compare the environmental impact of plastic bags compared to bags in various materials and to review how plastic bags are managed today, present a method for how to collect plastic bags for recycling in Borås and investigate whether it is environmentally viable. The results show that the determination of the environmental impact of different bags is a very complex issue because so many factors must be considered. We also see that the introduction of a separate recycling system for plastic bags is not the ultimate method when it would complicate logistics and require compression, to reduce their volume. The existing recycling system for plastic which blends hard plastic and soft plastic, is more convenient to use as it provides a denser mixture.

The improvement of environmental impacts from production and consumption is an important sustainability target for Belgium, defined in federal and regional strategies for sustainable development. In order to monitor the implementation of sustainability targets a framework that can consistently link production and consumption and assess multiple environmental impacts such as climate change or resource use is needed. The most recognised method for the quantification of environmental impacts of product systems is life cycle assessment (LCA). Most LCAs focusing on production and consumption activities are carried out at national level. However, when regional differences in production and/or consumption structure exist, which is the case for Belgium, the use of more regionalised datasets and assessments seems more appropriate. This PhD thesis develops a multi-regional environmentally extended input-output model (EE-MRIOM) that can account for regional variation in production and consumption patterns and analyse environmental impacts of products from life cycle perspective. The model analysis three Belgian regions (Brussels, Flanders, Wallonia with a special focus on the latter) and their connections via trade flows with the rest of the world. The regional input-output tables (IOTs) of Belgium were linked to a global input-output database (EXIOBASE) and integrated into the LCA framework. The initial regional environmental data on major air emissions were extended by resource use and other emission data, so that a wide spectrum of potential environmental impacts can be analysed. The model represents all economic activities in 2003, 2007 and 2010 with a higher resolution in environmentally important sectors (e.g. energy, construction products, waste).The analysis of environmental impacts from production and consumption perspective confirms the relevance of the life cycle thinking approach, as, for example only 10 % of Walloon household environmental impacts are direct impacts and only 20 % of the Walloon production-related impacts occur on the regional territory. The results show that certain environmental impacts of production have decreased due to the economic crises and structural changes, while environmental impacts from household consumption have increased during the same period. Therefore, we conclude that only the joint improvement from production and consumption perspective will effectively reduce environmental impacts and particular efforts from the consumer side are needed. The regional comparison of impact intensities indicates significant regional variation for production, at economy scale, but also at product level. However, the results do not suggest a systematically lower or higher environmental impact intensity for a certain region. From the household consumption perspective, the results indicate low regional variation when comparing environmental impacts on a per habitant basis. Based on the results from the regional comparison of impact intensities, we conclude that there is no universal concept that could be transferred from one region to the other to improve environmental impacts. Instead, product-specific best cases at a regional scale must be identified in order to propose improvement options. For the Walloon region ‘priority products’, i.e. products or services that contribute significantly to a certain impact category in terms of total impact and impact intensities, are identified with the developed EE-MRIOM. Further model applications are demonstrated in this work such as comparative assessment within a priority sector, detailed sector analysis and scenario analysis to support the policy-making process. The developed model helps to identify most efficient measures to reduce environmental impacts from production and consumption perspective and suggests further methodological developments. / Doctorat en Sciences / info:eu-repo/semantics/nonPublished

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / In front of the current and growing demand for natural resources, especially of the water resources, it seeks to find a way to minimize the impacts caused by the anthropic interference in areas of riparian vegetation. These environments have an important functionality to the ecosystems belonging and surrounding due to the fact of this vegetation possesses intrinsic characteristics and adapted to the hydro and ecological environment. The rivers barring for water use as an energy source (study subject of this work) cause various impacts to the environment, one of the major is the alteration of the natural regime of pulses and often, the reducing the downstream flow of the works. The flow reduction in certain stretches of the waterway, besides requiring an in-depth study about the impacts caused by the reduction of the downstream water level of the utilization section, it becomes essential to the vegetation analysis, soil and local geology. These related factors to the morphophysiological characteristics of the different species found in these locations will determine if the current ecosystem, observed in natural altimetric quotes previously found in the area of riparian vegetation, will be able to adapt to the lower quotes checked after implementation of the barring, in other words, in the stretch of reduced flow (SRF). For determination and differentiation of the vegetation it was necessary the study and development of a methodology of analysis by quotes. This analysis was performed using the points method that consisted of a classification and identification by functional character of the existing plants in three sampling units (SU's) located in the SRF of the hydroelectric unit Passo São João town of Roque Gonzales-RS. Furthermore, were performed the gathering of soil samples in the different quotes of the three SU's for physical and chemical analysis. Thus, it was possible to determine that the soil variable (physical and chemical characteristics), has no significant variation by quotes gap and therefore, are not considered necessary for studies of adaptive variations of the vegetation established there. However, in front of this fact and of the generated results, one can strengthen the hypothesis that the hydrological variable is directly responsible for the adaptive variation of the vegetal species in these areas. / Diante da atual e crescente demanda por recursos naturais, em especial dos recursos hídricos, busca-se uma forma de minimizar os impactos causados pela interferência antrópica em áreas de vegetação ribeirinha. Estes ambientes possuem uma importante funcionalidade aos ecossistemas pertencentes e circundantes devido ao fato desta vegetação possuir características intrínsecas e adaptadas ao meio hidro ecológico. O barramento de rios para utilização da água como fonte energética (objeto de estudo deste trabalho) causa vários impactos ao meio ambiente, um dos principais é a alteração do regime natural de pulsos e, muitas vezes, a redução da vazão a jusante das obras. A redução da vazão em determinados trechos do curso d´agua, além de necessitar um estudo aprofundado a respeito dos impactos causados pela redução do nível de água a jusante da seção de aproveitamento, torna-se indispensável a análise da vegetação, solo e geologia local. Estes fatores relacionados com as características morfofisiológicas das diferentes espécies encontradas nestes locais determinarão se o ecossistema atual, observado nas cotas altimétricas naturais anteriormente encontradas na área de vegetação ribeirinha, terá condições de se adaptar às cotas inferiores verificadas após a implantação do barramento, ou seja, no trecho de vazão reduzida (TVR). Para determinação e diferenciação da vegetação foi necessário o estudo e desenvolvimento de uma metodologia de análise por cotas. Esta análise foi realizada pelo método de pontos que consistiu em uma classificação e identificação por caracteres funcionais das plantas existentes em três unidades amostrais (UA‟s) locadas no TVR da UHE Passo São João, município de Roque Gonzales-RS. Além disso, foram realizadas coletas de amostras de solo nas diferentes cotas das três UA‟s para análise física e química. Desta forma, foi possível determinar que a variável solo (características físicas e químicas), não possuem variação significativa por intervalo de cotas e, portanto, não são consideradas necessárias para estudos de variações adaptativas da vegetação ali estabelecida. Contudo, diante deste fato e dos resultados gerados, pode-se fortalecer a hipótese de que a variável hidrológica é, de forma direta, responsável pela variação adaptativa das espécies vegetais destas áreas.

The evaluation of the costs involved in a production process becomes an increasingly essential tool for making decisions. In rice production there are several factors that may affect, directly or indirectly, the productivity and profitability. Besides the natural factors, like soil and climate, the choice of cultivar, the infra-structure and management system of the field, the logistic, and others, will be directly associated with the expected return of the investment. Besides these factors, is unthinkable to accomplish any activity without worry about an environmentally safe technology and production. The general objective of this dissertation is: search and compare the costs of production, productivity and environmental impacts between the systems of rice cultivars: Conventional, Clearfield and hybrid . Thus, the study started from the needs of a rice producer in the central region of Rio Grande do Sul State (Brazil) to know the production costs, productivity and environmental impacts associated with three types of rice cultivar systems most commonly used today, the Conventional Rice IRGA 417, IRGA 422 CL Clearfield System and the hybrid Arize 1003. Through unstructured interviews with the producer and the agronomist, observation "in loco" and documentary research lead to the production costs to be obtained for the goal of comparison in the diverse steps needed to the rice field production to facilitate data analysis and achieve the proposed goals. The results obtained allowed the producer the correct verification of which cultivar showed the highest efficiency in technical, economical end environmental subjects. / O levantamento dos custos envolvidos em um processo produtivo torna-se cada vez mais ferramenta imprescindível para a tomada de decisões. Na produção de arroz existem diversos fatores que podem afetar, direta ou indiretamente, a produtividade e a rentabilidade da atividade. Além dos fatores naturais como o solo e clima, a escolha da cultivar, a infra estrutura, o sistema de condução da lavoura e a logística, entre outros, estão associados diretamente ao retorno esperado do investimento. Além desses fatores, não se pode imaginar qualquer atividade sem a preocupação com tecnologia e produção ecologicamente correta. O objetivo geral desta dissertação é: apurar e comparar custos de produção, produtividade e impactos ambientais entre os sistemas de cultivo de arroz: Convencional, Clearfield e híbrido . Sendo assim, o estudo partiu da necessidade de um orizicultor da região central do Estado do Rio Grande do Sul (Brasil) de conhecer os custos de produção, a produtividade e os impactos ambientais associados aos três tipos de sistemas de cultivo de arroz mais usados atualmente: o Arroz Convencional (IRGA 417), Sistema Clearfield (IRGA 422 CL) e o híbrido (Arize 1003). Através de entrevistas não estruturadas com o produtor e o agrônomo, observação in loco e pesquisa documental foram apurados os custos de produção a fim de compará-los nas diversas fases necessárias para o cultivo do arroz visando facilitar a análise dos dados e alcançar os objetivos propostos. Os resultados apurados permitiram ao produtor a correta verificação de qual cultivar apresentou maior eficiência técnica, econômica e ambiental.

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / This present work has as main objective to engage in the environmental and social im'pacts analysis caused bu the construction of the Dona Francisca hidroelectric power plant situated in the central region of the Rio Grande do Sul state, Brazil. Initially, the work is based on reports of social impacts of the Dona Francisca hidroelectric power plant, to comprehend how the individuals that had chosen the rellocation based on great lot amount are studied and understood. Complementing this first analysis and the bibliographical review of authors that study general sociology, as Antony Giddens, Ignacy Sachs, Ulrich Beck and Amartya Sen to complement the same theories. These authors will help me to scope the tools used to analyse the social and environmental studies by stugying the effected individuals. The rationality was captured based on a structured questionário containing closed and opened questions. The closed questions part consisted in a description of the structual issue and social phenomenon that surroud the ressetled and its community. The opened questions explored issues that demanded a recall from the ressetlement, by considering the current social and economical life and also a projection of their future. The data showed that considering both closed and opened questions, it is clear some reflection points about the object. It was used the approach of Amartya Sen to make an analytical cleavage of the impacts in their lifes. The data demonstrated that in a general way, the individuals dont fit in the theory of human developing from Amartya Sen. Considering that, it is possible to comprehend that the ressetled individuals chase development trough the economical activities. The research demonstrates through epistemological data that it is necessessary to strengthen the social and environmental studies by using cases that exist already. These type of word would improve some solutions to those individuals. / Este trabalho tem por finalidade analisar os impactos socioambientais causados em decorrência da construção da Usina Hidrelétrica Dona Francisca, situada na região central do Rio Grande do Sul, Brasil. Esse trabalho conta inicialmente com a leitura detalhada dos relatórios de impacto ambiental, da usina em questão, para compreender como os indivíduos que escolheram o reassentamento por grandes lotes, são compreendidos pelos estudos. Complementando essa primeira análise, juntamente com a revisão bibliográfica dos autores que teorizam sobre uma sociologia geral, como Anthony Giddens, e através de autores selecionados para complementar a idéia do mesmo, como Ignacy Sachs, Ulrich Beck, Amartya Sen. Esses autores serão utilizados no empreendimento desse trabalho, que visa um refinamento das ferramentas utilizadas pelos estudos de impacto ambiental. Refinamento que é alcançado pelo pesquisador através da análise da racionalidade dos indivíduos que vivem nos reassentamentos. A compreensão é direcionada sobre as alterações e os impactos socioambientais que eles sentiram e que convivem, dez anos após o reassentamento. Alguns aspectos da racionalidade foram obtidos a partir de um questionário estruturado contendo perguntas fechadas e abertas. A parte fechada consistiu em uma descrição de questões estruturais e de fenômenos sociais que circundam o reassentado e sua comunidade. A parte aberta contou com questões que exigiam do entrevistado um exercício de rememoração do processo de reassentamento, através de sua situação social e econômica atual. Além disso, contou com uma atividade de projeção do que espera para seu futuro, frente suas expectativas de qualidade de vida. Constatou-se com essa pesquisa que a parte fechada, analisada descritivamente através do SPSS, e a parte aberta complementaram-se de modo a deixar claro alguns pontos de reflexão sobre o objeto. Utilizando a abordagem de Amartya Sen para realizar a clivagem analítica dos impactos socioambientais na qualidade de vida dos reassentados, foi possível compreender que os indivíduos analisados, de forma geral, não se encaixam na idealização de desenvolvimento humano de Amartya Sen. Sobretudo é possível compreender que outras formas de buscar o desenvolvimento, que não a econômica são pouco apontadas como saídas para seus problemas. A pesquisa assinala através do recorte epistemológico dado, o que é necessário fortalecer nos estudos de impacto ambiental, utilizando para isso, casos já existentes e análise dos problemas socioambientais, partindo do entendimento de quem o vive. A utilização deste saber local, juntamente com o resgate histórico das práticas sociais e econômicas no local de origem desses indivíduos são recursos mínimos para serem contemplados na formatação de medidas mitigadoras para indivíduos que vivem situações semelhantes.
