No. of bitstreams: 1 CIBELLE MARA REZENDE FELINTO - DISSERTAÇÃO (PPGECA) 2016.pdf: 3852337 bytes, checksum: 70e2fd1ed39a58e0a5b5613b077460c0 (MD5) Previous issue date: 2016-05-23 / Capes / Nesse estudo objetivou-se identificar a sustentabilidade da utilização dos recursos hídricos para João Pessoa, capital do Estado da Paraíba e localizada na Bacia Hidrográfica do rio Paraíba. Foram identificadas as principais forças motrizes, pressões, estado do meio ambiente e impacto sobre os recursos hídricos exercidos por essa cidade nas bacias em que ela está inserida, bem como as referidas medidas de respostas existentes e potenciais. A pesquisa utilizou-se do Sistema de Indicadores de Sustentabilidade Força Motriz-Pressão-Estado-Impacto-Resposta (FPEIR) para alcançar os seus objetivos. Após a montagem do modelo, foram selecionados 26 indicadores para representar a sustentabilidade das bacias, e alguns dos quais foram analisados em conjunto. Esses indicadores ajudaram a analisar a disponibilidade e a qualidade das águas superficiais e subterrâneas da região estudada. A aplicação do modelo FPEIR mostrou que os mananciais das duas bacias que abastecem João Pessoa não estão sendo geridos sustentavelmente. Os resultados mostram que a população de João Pessoa exerce notável pressão sobre os recursos hídricos das bacias em estudo em ambos os aspectos: qualitativo e quantitativo. Evidencia-se, ainda, a necessidade de serem realizadas avaliações frequentes das condições de sustentabilidade das bacias hidrográficas envolvidas. Para isso, é necessário a atualização periódica dos dados referente às bacias, desenvolvendo estudos que possam auxiliar no planejamento integrado. / This study aimed to identify the sustainable use of the water resources to João Pessoa, the state capital of Paraíba, located in the basin of the river Paraíba. The main driving forces were identified, pressures, state of the environment and impact on the water resources held by this city in the basins in which it operates, as well as the measures of existing and potential responses. The research used the Sustainability Indicator System Driver-Pressure-State-Impact-Response (DPSIR) to achieve their goals. After fitting the model, were selected 26 indicators to represent the sustainability of basins and indicators 26 have been identified, some of which were analyzed together. These indicators helped to analyze the availability and quality of the surface and groundwater in the region studied. The application of DPSIR model showed that the sources of the two basins that supply Joao Pessoa are not being managed sustainably. The results show that the population of Joao Pessoa exerts considerable pressure on the water resources in the basins studied in both aspects: qualitative and quantitative. It is evident also need to be carried out frequent assessments of the conditions of sustainability of watersheds involved. This requires periodic updating of data related to basins, developing studies that can assist in the integrated planning.

FundaÃÃo Cearense de Apoio ao Desenvolvimento Cientifico e TecnolÃgico / O planejamento e gestÃo ambiental em uma bacia hidrogrÃfica sÃo necessÃrios para o estabelecimento da utilizaÃÃo adequada dos recursos naturais existentes. Daà se ressalta a importÃncia de estudos que reÃnem e discutam os aspectos naturais, econÃmicos e sociais que influenciam na dinÃmica daquela unidade ambiental. Com efeito, realizou-se o diagnÃstico ambiental da bacia hidrogrÃfica do rio Guaribas, litoral oeste do CearÃ, Nordeste do Brasil, com a aplicaÃÃo de indicadores do modelo DPSIR (Driving Forces, Pressures, State, Impact, Responses). Dentre os objetivos especÃficos, citam-se: (i) realizar a caracterizaÃÃo ambiental e socieconÃmica da bacia hidrogrÃfica do rio guaribas, (ii) analisar o conjunto de indicadores do modelo DPSIR como instrumento de apoio à tomada de decisÃo no Ãmbito de polÃticas pÃblicas, (iii) Forncer um conjuto de propostas que visam melhorar a qualidade de vida da populaÃÃo presete na Ãrea de estudo. O embasamento teÃrico-metodolÃgico foi alicerÃado no modelo conceitual DPSIR, desenvolvido pela OrganizaÃÃo para a CooperaÃÃo e Desenvolvimento EconÃmico em 2002. O modelo citado privilegia a anÃlise das relaÃÃes ecossistÃmicas e antropogÃnicas inseridas nos sistemas ambientais presentes na Ãrea de estudo. Desse modo, a pesquisa proporcionou uma anÃlise integrada dos problemas ambientais em relaÃÃo Ãs causas que os produzem, sendo ainda incluso as respostas entendidas como aÃÃes propositivas que podem ser fomentadas e desenvolvidas pelas administraÃÃes pÃblicas, pela sociedade civil e pelos setores econÃmicos. Entende-se que a apropriaÃÃo do espaÃo na Ãrea de estudo ocorre em funÃÃo do processo de urbanizaÃÃo, das instalaÃÃes do complexo portuÃrio e da utilizaÃÃo dos recursos naturais, atraÃdos pela polÃtica de desenvolvimento econÃmico estadual que, ao entrar em conflito com as comunidades tradicionais, evidencia uma distribuiÃÃo desigual dos usos do espaÃo litorÃneo. Assim, à possÃvel afirmar que a aplicabilidade do modelo DPSIR foi de grande relevÃncia, pois proporcionou uma anÃlise integrada dos problemas socioambientais, sendo ainda incluso as aÃÃes propositivas que podem ser fomentadas pelas administraÃÃes pÃblicas, sociedade civil e setores econÃmicos. Considera-se que hà necessidade urgente de disciplinamento na utilizaÃÃo dos ambientes litorÃneos presentes no setor oeste do Estado do CearÃ. / The planning and environmental management within a watershed are needed to establish the appropriate use of natural resources. From this, it is emphasized the importance of studies that gather and discuss the aspects of natural, economic and social dynamics that influence the environmental unit. In effect, it was done the environmental diagnosis of river basin of Guaribas, west coast of CearÃ, Northeast of Brazil, with the application of indicators of DPSIR model (Driving Forces, Pressures, State, Impact, Responses). Among the specific objectives are: (i) identify the main environmental problems affecting the population that inhabits the river basin of Guaribas, (ii) analyze the set of indicators of the DPSIR framework as a tool to support decision making in context of public policy, (iii) identify the actions needed to solve the environmental problems found in the study area. The theoretical and methodological framework was founded on DPSIR conceptual model, developed by the Organization for Economic Cooperation and Development in 2002. The above model focuses on the analysis of the ecosystemic and anthropogenic relationships embedded in the environmental systems present in the study area. Thus, the research provided an integrated analysis of environmental problems in relation to the causes that produce them, and even included the answers understood as purposeful actions that can be fostered and developed by government, civil society and economic sectors. It is understood that the appropriation of space in the study area occurs as a result of the urbanization process, the facilities of the port complex and the use of natural resources, attracted by the policy of state economic development state that, when conflict with the traditional communities, shows an uneven distribution of uses of coastal space. Thus, it was possible to say that the applicability of the DPSIR model was of great importance because it provided an integrated analysis of environmental problems, which still included the purposeful actions that can be fostered by government, civil society and economic sectors. It is considered that there is urgent need for discipline in the use of coastal environments present in the western sector of the State of CearÃ.

En France, les phénomènes de périurbanisation imposent une réflexion sur les conditions d’un développement urbain durable. En zone languedocienne, dans un contexte de forte attractivité démographique, l'urbanisation rapide et mal maîtrisée se fait aux dépens des terres agricoles les plus productives de la région, sur la plaine littorale. L’évolution des demandes sociales et les enjeux autour de la sécurité alimentaire mondiale interrogent sur la façon dont les politiques de planification périurbaine intègrent le foncier agricole. Pour objectiver les débats et appuyer les décisions, les instances agricoles expriment des besoins urgents en indicateurs spatialisés. L’objectif de cette thèse est de proposer une démarche de co-construction d’un système d’indicateurs pour suivre les processus d’artificialisation des terres. Modélisation systémique et concertation itérative ont été retenues comme les approches adaptées pour guider le processus de constitution et de sélection des indicateurs. Cette recherche revisite le modèle DPSIR en l’adaptant au concept de système territorial et propose d’organiser la participation des acteurs pour garantir une légitimité d'utilisation des indicateurs. L’application de la méthode, inscrite dans des impératifs d’opérationnalité, porte sur la production et la mise à disposition en ligne d’un ensemble organisé de 141 indicateurs spatialisés liant l’évolution du capital foncier à celle de la tache artificialisée languedocienne. / In France, suburbanization phenomena impose to think the conditions for sustainable urban development. In the Languedoc region, in a context of a strong demographic attractiveness, fast and uncontrolled urbanization happens at the expense of the most productive farmland in the region, on the coastal plain. The evolution of social demands, as well as issues around food security on a world scale, raise the question how suburban planning policies deal with the agricultural land issue. In order to objectify discussions and support the decisions, the agricultural authorities have expressed an urgent need for spatial indicators. The objective of this thesis is to propose an approach to co-build a system of indicators so as to monitor the land urbanization process. Systems modeling and iterative consultation were chosen as the appropriate approaches to lead the making up process and the selection of indicators. This research revisits the DPSIR model by adapting it to the concept of territorial system and proposes to organize the participation of stakeholders to ensure legitimacy for the use of indicators. The method application, part of the operational requirements, covers the production and availability online of a structured set of 141 spatial indicators linking the evolution of land assets and the one of the languedocian “artificialized patch”.
