All living things mostly the humans, as builders of civilizations, have always been in intrinsic bonds with water. This interaction between water (oceans, seas, lakes, rivers etc.) and settlements has existed since ancient civilizations. Among water resources, &lsquo / flowing waters&rsquo / such as rivers, streams, creeks, etc. have a prominent role as they are the lifeblood of most cities in terms of providing transportation, security, energy, irrigation, commerce, and recreation. By the late 19th century, developments of terrestrial transportation modes diminished the magnetism of rivers and riverfronts, and growing industries led to the deterioration of rivers. Owing to these reasons, along with many others, they turned into sewage channels, were covered up, and became water scopes detached from the urban life. Particularly since the 1970s, with more attention given to sustainability of resources, a greater awareness has grown of the vital role of urban rivers as a resource for humans and a lifeline for cities. After being neglected for decades, urban rivers have started to be rehabilitated to solve the related problems. The new approach to urban river rehabilitation beyond classical practices that aim at recovering the physical conditions of rivers has come to the fore to address the problems comprehensively. Instead of independent and one-dimensional practices, the urban rivers have become to be seen as a vital part of urban water system and of the city itself. While rehabilitating urban rivers, recovering river health can be ensured provided that the entire urban water ecosystem is taken into consideration. The ecocity approach is one of the major new approaches that geared toward achieving a healthy city, and sustainability of water system is the significant goal within this approach. In this regard, the thesis first asserts that the ecocity criteria are likely to give way to a more sustainable future for urban rivers. Besides being a part of the ecosystem, urban rivers have transformed together with the surrounding built environment throughout the history of cities. Significant focal elements of the urban pattern, urban rivers should be dealt with other urban focal points, with the introduced concept of river-city integration, which is proposed as the second assertion of the thesis. In this respect, the study attempts to investigate urban rivers and their rehabilitation in relation with both the ecocity approach, and the river-city integration concept. The research methodology in the present study involves comparative anaysis of best practices and case study analysis. Porsuk River and the city of Eskisehir, which the river passes through, were selected as a case for empirical study. Criteria sets that determined within the frames of ecocity and river-city integration, and the testing of the criteria in the case area offers an opportunity to contribute to literature of river and city coexistence.

Relatively little published information on cyanoprokaryote (blue-green algal) blooms in the freshwater wetlands in Western Australia is available. There has been little research on the urban lakes and rivers, examining the relationship between environmental conditions and toxin-producing blooms. In this project the ecology, morphology and toxicity of cyanoprokaryota blooms in 27 metropolitan lakes and sumplands, as well as three major rivers, from 2000 to 2003, on the Swan Coastal Plain (SCP) in the southwest of Western Australia were investigated. / A total of 24 species were identified and described, of which nine species had not been previously documented in the area. This included the potentially toxic species Cylindrospermopsis raciborskii, Aphanizomenon ovalisporum and Anabaena bergii var. limnetica. An illustrated guide to the common bloom-forming species was generated using conventional taxonomic criteria. / Microcystis flos-aquae and Microcystis aeruginosa were the dominant bloom-forming cyanoprokaryotes, widespread in their distribution. Anabaena circinalis, A. bergii var. limnetica and Anabaenopsis elenkinii were the common filamentous species. Anabaena circinalis was common to certain freshwater sites, while A. bergii var. limnetica and A. elenkinii occurred in salinity ranging from fresh (< 1ppt) to hyposaline (3-10 ppt). Sites with similar species assemblages were identified using two-way indicator species analysis and clustering analysis. From this, a distinct distribution pattern emerged, which was defined by the main genera observed in the lakes – Microcystis, Anabaena, Aphanizomenon and Anabaenopsis. / The spatial and temporal distribution of the common bloom-forming cyanoprokaryote species was examined in conjunction with spring-summer physico-chemical data using principal component analysis. It was found that pH, water temperature and electrical conductivity/salinity accounted for variations among the lakes, with electrical conductivity the variable explaining the greatest variation. Lakes located on the coast, or further inland at the base of the Darling Scarp, were more hyposaline to saline, and the remaining lakes were fresh. Although the SCP lakes form consanguineous groups based on geochemistry and hydrology, no similarities among them were found in terms of water quality. / The relationship between nitrogen (N) and phosphorus (P) concentrations (total and dissolved inorganic) and cyanoprokaryote community structure (N-fixing versus non-N-fixing species) was investigated in five selected lakes; Yangebup Lake, Bibra Lake, Blue Gum Lake, Tomato Lake and Emu Lake. The lakes ranged from mesotrophic to eutrophic and supported spring-summer blooms containing multiple species. Overall an inverse relationship between cyanoprokaryote abundance and total ambient nutrient concentrations at the time of the blooms was evident. No transition in dominance in the community was observed in Yangebup Lake, Emu Lake and Bibra Lake, as they were dominated by non-heterocytic species (M. aeruginosa and M. flos-aquae) throughout spring and summer. For Yangebup Lake and Bibra Lake, the abundance of non-heterocytic species decreased concomitantly with decreasing dissolved inorganic N. In contrast, heterocytic species (A. circinalis) dominated the spring community in Tomato Lake, and summer community in Blue Gum Lake, when N and P concentrations were at their highest. / The presence of microcystins in Microcystis dominated blooms was examined using high performance chromatography. A total of 32 natural bloom samples, representing 13 lakes, were analysed for microcystin variants; -LR, -RR and -YR. Twenty-eight samples proved to be toxic with the highest total microcystin concentration from 1645 to 8428.6 µg L[superscript]-1, the lowest concentrations were less than 10 µg L[superscript]-1 with some below the detection limit. Microcystis aeruginosa and M. flos-aquae were associated with these microcystin-containing blooms, although M. flos-aquae appear to be less toxic. The presence of Nodularia spumigena in the Lake Yangebup was associated with high concentrations of nodularin (1664 µg L[superscript]-1). / Employing enzyme-linked immunosorbent assay for microcystins and the brine shrimp (Artemia) bioassays allowed a greater number of lake samples to be analysed and provided a rapid assessment of toxicity. The three methods for cyanotoxin detection verified Yangebup Lake, Herdsman Lake, Hyde Park, Jackadder Lake and Emu Lake as highly toxic sites. Low toxicity was demonstrated in samples from Lake Goollelal, Lake Joondalup, Lake Claremont, Blue Gum Lake and North Lake. These results provided the first evidence of cyanotoxin producing blooms in urban lakes of the SCP. / A comparative study on cyanoprokaryota blooms in Swan River estuary, upper Canning River and upper Serpentine River found that these sites, although hyposaline to saline, contained species that were common in the freshwater lakes. Sampling the river systems showed M. aeruginosa, M. flos-aquae, A. circinalis, A. elenkinii and Planktothrix planctonica to be cosmopolitan in distribution, present in SCP wetlands of varied salinity. Similarities between the upper Canning River and lakes in environmental conditions and species assemblage were demonstrated using multivariate analyses. / Toxin analysis of bloom samples from the Swan River and upper Canning River revealed microcystin concentrations were less than that of the surrounding lakes (1.05-124.16 µg L[superscript]-1). Similarly, nodularin concentrations were higher in Yangebup Lake than the upper Serpentine River. However, the dominance of Anabaena in Canning River samples, and the highly toxic result from the Artemia bioassay suggests microcystin is not the predominant cyanotoxin in this wetland. / This study has produced an overview of the distribution and morphology of cyanotoxin-producing cyanoprokaryotes in the SCP wetlands. The data presented provide the basis for further cyanoprokaryote research in Western Australia, in particular the molecular characterisation of bloom-forming toxic species.

A preocupação com recursos hídricos tem sido crescente em meios urbanos. O despejo de resíduos sólidos em rios é comum por populações ribeirinhas, favorecendo a ocorrência de enchentes, a proliferação de vetores e doenças e o desprezo da comunidade pelos rios. Nesse contexto, programas que relacionam lixo, recursos hídricos e população ribeirinha têm sido objeto de várias iniciativas governamentais. Este trabalho busca avaliar uma delas: o Programa Municipal de valorização de rios e lagoas Águas do Rio (Guardiões dos rios) que foi desenvolvido pela prefeitura do Rio de Janeiro entre abril de 2001 a março de 2008. O programa buscou aliar interesses de ordem técnica, de saúde pública e de cunho social para a comunidade por utilizar mão de obra local para a manutenção da calha do rio, visando à retirada de lixo e entulhos do rio, geralmente em áreas de pequena extensão territorial, com manutenção adequada de margens e entornos. A partir de entrevistas abertas e questionários aplicados junto aos envolvidos de 27 frentes de trabalho, constatou-se um resultado bastante positivo nas comunidades onde o Programa foi implantado: diminuição de enchentes, redução de vetores e melhoria da paisagem urbana. Contudo, observou-se também profundo descontentamento com a interrupção do Programa, atribuído principalmente ao uso indevido por determinados políticos (ampliação descontrolada do Programa com abandono de critérios técnicos) e a transferência da sua gestão para uma instituição municipal que não o manteve funcionando. Conclui-se, sobretudo, que o Programa Guardiões dos rios é uma iniciativa criativa de ações emergenciais em rios urbanos, em nível municipal, que combina a retirada de lixo dos rios, um trabalho social e campanhas de educação ambiental junto às comunidades. / The worry with water resources has increased in urban areas. The dumping of solid waste is common and done by riverside populations which favor the occurrence of flood, the increasing of vectors, the spread off illnesses and the populations refuse to care for the rivers. In this context, programs that include garbage, water resources and riverside population have been the aim of lots of government initiatives. The objective of this research is to assess the results of one of them: the City Program of making rivers and lakes worthwhile The River Waters of Rio ("The River Guardians") that was developed by the city hall of Rio de Janeiro from April from 2001 to March of 2008. The program tried to form an alliance with technical order, public health and of social interests to the population for using local labor to maintain the river to aim taking the garbage of the river, generally in small areas, with the adequate maintenance of the bank and surrounding areas of rivers. From interviews and questionnaires given to 27 labor fronts, a positive result has been brought to the Program had been introduced: the fall of flood and vectors and also the improvement of the urban view. However, people realized a profound unhappiness with the Program break, related mainly to the wrong usage of some politicians (the out of control enlargement of the Program with of technical withdraw) and the management transfer to a municipal institution that did not maintain this program working. Its been concluded that the Program The River Guardians is a creative initiative of emergencial actions in urban rivers, at municipal level, that combines the taking off rivers garbage, a social work and environmental education campaigns in the communities.

Os problemas ambientais são cada vez mais comuns e de magnitudes e escalas variadas, atingindo principalmente as áreas urbanas. Poluição atmosférica e dos corpos dágua, deslizamentos de encostas e enchentes são alguns dessas situações adversas. São Gonçalo não foge á regra. Localizada na Região Metropolitana do Rio de Janeiro, essa cidade sofre com as situações exemplificadas, principalmente em relação a degradação dos rios urbanos e as enchentes que acometem algumas áreas do município. Partindo-se da problemática exposta, a presente pesquisa tem como objetivo principal promover uma discussão teórica e reflexiva sobre a importância da efetivação da educação ambiental com foco na bacia hidrográfica urbana, tomando-se a bacia hidrográfica do rio Imboassú no município de São Gonçalo (RJ), como recorte. A fundamentação metodológica deste trabalho está pautada na análise ambiental que prioriza a participação pública e a educação ambiental no processo de planejamento e gestão, visando minimizar as diversas situações de desequilíbrio e degradação que acometem a bacia. A operacionalização deu-se do seguinte modo: análise inicial a partir da sistematização de estudos diagnósticos e de consultas de documentos, relatórios, dentre outros de órgãos governamentais; análise intermediária a partir da observação em campo do atual estado de degradação da bacia hidrográfica do rio Imboassú e da identificação do conjunto de políticas públicas vigentes; análise integrada análise dos estudos diagnósticos, análise da situação atual da bacia (in loco e documental), análise final com identificação de lacunas de gestão e propostas viáveis no âmbito da educação ambiental. Verificou-se que essa bacia está urbanizada e os rios que a compõem descaracterizados e poluídos, com histórico de enchentes. Falta de ordenamento urbano, degradação ambiental e descaso do poder público são alguns problemas enfrentados pelos moradores dessa bacia, resultando na falta de ordenamento territorial urbano e falta de qualidade de vida da população. Diante do exposto, fica claro a necessidade de se criar mecanismos que amenizem essa degradação e tragam equilíbrio ao funcionamento e dinâmica da bacia, influenciando positivamente o dia-a-dia da população residente em seu interior. Um eficiente caminho para promover essa mudança é a educação ambiental como ferramenta para a transformação da sociedade, conscientizando-a de seu papel participativo e modificando a maneira como esta se relaciona com o meio ambiente. Verificou-se que na prática, na bacia do Imboassú, o poder público não efetiva os pressupostos presentes, tanto na legislação ambiental, quanto no plano diretor municipal e alguns órgãos (CEDAE, INEA, SEMMA) não atuam de forma satisfatória. Logo, levantar a discussão da importância da Educação Ambiental como política pública a ser promovida pelos gestores municipais e apontar para a participação e atuação da sociedade de forma crítica na estruturação do espaço urbano é de extrema importância para promover melhoria na relação sociedade meio ambiente. / Environmental problems are increasingly common and varying magnitudes and scales, affecting mainly the urban areas. Air pollution and water bodies, landslidesand floods are some of these adverse situations. São Gonçalo is no exception. Located in the Metropolitan Region of Rio de Janeiro, the city has exemplified with situations, especially in relation to degradation of urban rivers and floods affectingsome areas of the city. Based on the problems exposed, this research has as main objective to promote a reflective and theoretical discussion about the importance of effective environmental education with a focus on urban watershed, taking the river basin Imboassú in São Gonçalo ( RJ), such as clipping. The methodological foundation of this work is based in the environmental analysis that prioritizes environmental education and public participation in planning and management in order to minimize the number of imbalances and degradation that affect the basin. The operation took place as follows: initial analysis from the systematic diagnostic studies and consultation documents, reports, among other government agencies; interim analysis from the field observation of the current state of degradation of river basin Imboassú and identify the set of policies in force, integrated analysis - analysis of diagnostic studies, analyzing the current situation of the basin (on-site and documentary), the final analysis to identify gaps in management and viable proposals in the context of environmental education. It was found that the basin is urbanized and the rivers that make up the defaced and polluted, with a history of flooding. Lack of urban planning, environmental degradation and neglect of the public are some problems faced by residents of the basin, resulting in the disorder and lack of urban land quality of life. In this light, it is clear the need to create mechanisms that mitigate this degradation and bring balance to the function and dynamics of the basin, positively influencing the lives of the residents inside. An efficient way to promote such change is the environmental education as a basis for transformation of society, making them aware of their role in participatory and modifying the way it relates to the environment. It was found that in practice the government did not effectively present the assumptions, both in environmental legislation, as in the municipal master plan and some organs (CEDAE, INEA, SEMMA) do not work satisfactorily. So raise the discussion of the importance of environmental education as public policy to be promoted by municipal and point to the participation and performance in a critical society in the structuring of urban space is extremely important to promote better value society - environment

Ces espaces se sont rendus alternative d'accès au logement pour une masse de pauvres qui ne peuvent pas acquérir un espace sûr la ville. La jonction de pauvreté, d'habitation improvisée, peu d'infrastructure, avec l'occupation d'espaces exposés à des aléas naturels, a créé des territoires de risques et des vulnérabilités, qui fréquentement coïncident avec les environnements fluviaux urbains. Ainsi, il s'est défini comme principale proposition de cette thèse analyser les risques et les vulnérabilités socio-environnementaux de fleuves urbains au Brésil, en ayant le bassin hydrographique du fleuve Maranguapinho, localisé dans la Région Métropolitaine de Fortaleza - RMF, Ceará, comme espace d'étude de cas pour compréhension des interrelations entre des vulnérabilités sociales et exposition aux risques naturels, principalement les risques d'inondations. La méthodologie utilisée a employé des techniques statistiques, de la superposition cartographique, des incursions dans l’espace d’étude, pour produire un indice de vulnérabilité socio-environnementaux du secteur étudié. Il s'est conclu qu'il y a des forts coïncidences entre les espaces susceptibles à des processus naturels dangereux, comme est le cas des inondations - processus naturel remorque à la dynamique des fleuves et de leurs bassins hydrographiques, et les espaces de la ville qui présentent les pires indicateurs sociaux, économiques et de l'accès à des services et l'infrastructure urbaine / Os rios urbanos no Brasil são sinônimos de ambientes degradados, desvalorizados e negados pela sociedade. Esses espaços se tornaram a alternativa de acesso à moradia para uma massa de pobres que não podem adquirir um espaço seguro na cidade. A junção de pobreza, habitação improvisada, pouca infraestrutura, com a ocupação de espaços expostos a perigos naturais, criou territórios de riscos e vulnerabilidades, que frequentemente coincidem com os ambientes fluviais urbanos. Assim, definiu-se como principal proposta desta tese analisar os riscos e as vulnerabilidades socioambientais de rios urbanos no Brasil, tendo a bacia hidrográfica do rio Maranguapinho, localizada na Região Metropolitana de Fortaleza – RMF, Ceará, como área de estudo de caso para compreensão das inter-relações das vulnerabilidades sociais e exposição aos riscos naturais, principalmente os riscos de inundações. A metodologia utilizada empregou técnicas estatísticas, sobreposição cartográfica, trabalhos de campo, para produzir um índice de vulnerabilidade socioambiental da área estudada. Concluiu-se que há fortes coincidências entre os espaços susceptíveis a processos naturais perigosos, como é o caso das inundações – processo natural atrelado à dinâmica dos rios e de suas bacias hidrográficas, e os espaços da cidade que apresentam os piores indicadores sociais, econômicos e de acesso a serviços e infraestrutura urbana / The urban rivers in Brazil are synonymous of degraded, devaluated and denied environments for the society. These spaces had become the alternative access to housing for a mass of poor persons who cannot acquire a safe space in the city. The junction of poverty, improvised habitation, little infrastructure, with the occupation of prone spaces to the natural hazards, created territories of risks and vulnerabilities, that frequently coincide with urban fluvial environments. Thus, the main proposal of this thesis is to analyze the risks and the socioenvironmental vulnerabilities of urban rivers in Brazil, having being chosen the the Maranguapinho river hydrographic basin as case study area, located in the Metropolitan Region of Fortaleza - MRF, Ceará, to the understanding of the inter-relations between social vulnerabilities and exposure to the natural risks, mainly the risks of floodings. The methodology used statistical techniques, cartographic overlapping, field research, to produce an socio-environmental vulnerability index of the case study area. It was concluded that it has serious coincidences between the susceptibles spaces to natural hazards processes, e.g floodings – natural process linked to the rivers’ dynamics and its hydrographic basin, and the spaces of the city that present the worse social, economic, access the services and urban infrastructure index

Diante das modificações ocorridas com o crescimento urbano ao longo dos anos e a consequente falta de saneamento básico observada no início deste crescimento, a degradação dos rios e córregos da Região Metropolitana de São Paulo foram devastadoras para a sua qualidade, trazendo desconforto e doenças de veiculação hídrica para a população do entorno. Este projeto tem por objetivo analisar como os corpos dágua que não possuem relevância para o abastecimento e que estão localizados na Bacia do Alto Tietê estão sendo tratados pela legislação e por seus gestores, compilando as ações tomadas que favorecem a despoluição dos mesmos. Desenvolveu-se uma pesquisa qualitativa de estudo de caso, com caráter exploratório a partir de dados fornecidos pelo Comitê de Bacia Hidrográfica do Alto Tietê e dados secundários. Conclui-se que apesar de ser discutido dentro do Comitê, os corpos hídricos inseridos na Região Metropolitana de São Paulo não possuem grande importância, tendo o Comitê assuntos prioritários, como abastecimento, assim como a destinação de recursos indicados e aprovados pelo FEHIDRO e os investimentos da SABESP / In the face of the changes that have occurred with urban growth over the years and the consequent lack of basic sanitation observed at the beginning of this growth, the degradation of the rivers and water streams of the São Paulo Metropolitan Area were devastating to its quality, bringing discomfort and waterborne diseases of circulation for the surrounding population. The objective of this project is to analyze how the water bodies among those that do not have relevance for the supply and that are located in the Alto Tietê Watershed are being treated by the legislation and its managers, compiling the actions that were taken to favor the depollution of those specific kind of water body. A qualitative study of a case study was developed, with an exploratory character based on data provided by the Committee of the Alto Tietê Watershed and secondary data. It was concluded that, despite being discussed within the Committee, the water bodies inserted in the São Paulo Metropolitan Region are not of great importance, with the Committee having priority subjects, such as supply, as well as the allocation of resources indicated and approved by FEHIDRO and investments of SABESP

A presente tese analisa o processo de apropriação privada dos rios de São Paulo e sua participação na produção do espaço da cidade, aprofundando aspectos relativos ao desenvolvimento social, político e econômico, desde sua fundação no século XVI até o início do século XX. Partindo das obras de canalização dos rios Tamanduateí, Tietê e Pinheiros, a pesquisa realiza um recuo histórico até o momento em que os rios e córregos de São Paulo se constituíam como um bem comum e sua principal característica era o uso de suas águas e terras. As diversas atividades relacionadas aos rios e córregos, nos primeiros séculos da ocupação, caracterizam-se pela convivência entre o consumo imediato, a utilização de mão de obra cativa e a obtenção de renda através do trabalho livre, em um momento em que a economia de São Paulo era tímida e a poluição dos rios já era percebida. Durante o século XIX, a partir da cultura do café e da imigração, estabeleceu-se uma economia baseada no trabalho livre assalariado e na valorização da propriedade fundiária. Na cidade de São Paulo, o crescimento populacional e a insuficiência da distribuição de água e esgotamento, associados ao significado econômico da propriedade e a disponibilidade de mão de obra, passaram a representar a possibilidade de valorização do capital a partir do estabelecimento de condições gerais de produção. Os rios de São Paulo foram então incorporados ao processo de provisão de infraestruturas e redes de serviços urbanos. Esse processo de acumulação de riqueza, baseado na expropriação da terra e da água, transformou os rios de São Paulo em recursos econômicos e engendrou um espaço que se caracteriza pela sobreposição do domínio particular sobre o domínio comum. / This thesis analyzes the process of private appropriation of the São Paulo and his participation in the production of the city\'s space, Aspects related to social, political and economic development, From its foundation in the 16th century to the beginning of the 20th century.
