This objective was outlined when we noted a large number of households (about 2000) located in an area considered relevant in terms of environmental and social conditions, notably because of the existence of lakes, sand dunes and rivers that contribute to groundwater recharge Dunas/Barreiras Furthermore, this area is widely used for agricultural activities. The methodology used during this research is accorded to the literature review about the concept of vulnerability, consultations in public agencies for data acquisition, field research and questionnaires. Data collected from each category of vulnerability (social and environmental) were tabulated, analyzed and presented as tables, maps and texts. According to theoretical concepts and methodology of Alves (2006), Cutter (1996), Torres (2000), Acselrad (2006) e Hogan e Marandola Junior (2005; 2006; 2007), the research is structured in the preparation of an environmental diagnosis of the neighborhoods of Blue Lagoon and Paju?ara and subsequent analysis of socio-environmental vulnerability in the Zone of Environmental Preservation -9, especially Area 1, 2 and 3.There was a variation in results between the social vulnerability and environmental vulnerability categories for each area of the Zone of Environmental Preservation -9. However, the crossing between the two categories above showed that Area 3 had the highest level of environmental vulnerability, followed by Area 1. On the other hand, the Area 2 was considered of minor environmental vulnerability. In this sense, this work presents relevant subsidies to the planning of public policies, to identify and characterize the critical areas with high socio-environmental vulnerability / A presente pesquisa tem por objetivo analisar a vulnerabilidade socioambiental na Zona de Preserva??o Ambiental -9, localizada na zona administrativa norte do munic?pio de Natal/RN. Este objetivo foi tra?ado ao constatarmos um n?mero elevado de resid?ncias (cerca de 2.000) situadas em uma ?rea considerada relevante do ponto de vista ambiental e social, notadamente pela exist?ncia de lagoas, dunas e rios que contribuem para a recarga do aq??fero Dunas/Barreiras, al?m de ser uma ?rea largamente utilizada para atividades agr?colas. Fundamentada na revis?o bibliogr?fica sobre o conceito de vulnerabilidade, consultas em ?rg?os p?blicos para aquisi??o de dados, al?m da pesquisa de campo e aplica??o de question?rios. Os dados coletados de cada categoria da vulnerabilidade (social e ambiental) foram tabulados, analisados e apresentados em forma de tabelas, mapas e textos. Baseando-se nas concep??es te?ricas e metodol?gicas de Alves (2006), Cutter (1996), Torres (2000), Acselrad (2006) e Hogan e Marandola Junior (2005; 2006; 2007) a pesquisa esta estruturada na elabora??o de um diagn?stico socioambiental dos bairros de Lagoa Azul e Paju?ara e a posterior an?lise da vulnerabilidade social e ambiental da Zona de Preserva??o Ambiental-9, notadamente as ?reas 1, 2 e 3. Constatou-se uma varia??o nos resultados entre as categorias vulnerabilidade social e vulnerabilidade ambiental para cada ?rea da Zona de Preserva??o Ambiental-9. Entretanto, o cruzamento entre as duas categorias citadas mostrou que a ?rea 3 apresentou o maior n?vel de vulnerabilidade socioambiental, seguida da ?rea 1. J? a ?rea 2 foi considerada de menor vulnerabilidade socioambiental. Neste sentido, este trabalho tr?s subs?dios relevantes para o planejamento de pol?ticas p?blicas, ao identificar e caracterizar as ?reas cr?ticas, com alta vulnerabilidade socioambiental

From the analysis of the remaining railway assets along the line and its relation with the formed urban tissues, it is intended to reflect on the selection and preservation criteria of the cultural heritage. To understand the dynamics that operate in the studied territory, two groups of territorial analysis are developed that cover the three municipalities: the first group presents the urban physical expansions in spots, dated for periods of 20 in 20 years; The second presents the land uses of the Cia. Paulista railway. The analyzes are intended to interweave changes in the territory and the remaining rail heritage in this set of cities, where the railway and its stations formed the whole responsible for the first urbanization of these cities. As a result of this process is obtained the conformation of a characteristic landscape, conformed by the railway axis. For the recognition of these remnants, the analysis of new concepts of protection, such as the cultural landscape and the cultural itinerary, both published by UNESCO, made it possible to note how the preservation, conservation and promotion policies of cultural heritage in the municipal spheres are still fragile and Unprepared to face the preservation of more complex sets. / A pesquisa prop?e-se a estudar a implanta??o da antiga Cia. Paulista de Estradas de Ferro e a import?ncia da linha na forma??o e configura??o das cidades m?dias e pequenas paulistas, especificamente as cidades de Vinhedo, Valinhos e Louveira, do trecho da linha entre Campinas e Jundia?. A partir da an?lise dos patrim?nios ferrovi?rios remanescentes ao longo da linha e sua rela??o com dos tecidos urbanos formados, pretende-se refletir sobre crit?rios de sele??o e preserva??o dos bens. Para entender as din?micas e os fen?menos que atuam no territ?rio estudado, desenvolvem-se dois grupos de an?lise territorial que abrangem os tr?s munic?pios: o primeiro grupo apresenta as expans?es f?sicas urbanas em manchas, datadas por per?odos de 20 em 20 anos; o segundo apresenta os usos do solo do entorno da ferrovia da Cia. Paulista. As an?lises t?m o intuito de entrecruzar as mudan?as ocorridas no territ?rio e o legado ferrovi?rio remanescente neste conjunto de cidades, onde a ferrovia e suas esta??es formavam o conjunto respons?vel pela primeira urbaniza??o destes n?cleos. Como resultado desse processo obt?m-se a conforma??o de uma paisagem caracter?stica, conformada pelo eixo ferrovi?rio. Para a recogni??o destes remanescentes, a an?lise de novos conceitos de prote??o, como a paisagem cultural e o itiner?rio cultural, ambos chancelados pela UNESCO, possibilitou constatar o quanto as pol?ticas de preserva??o, conserva??o e promo??o do patrim?nio cultural nas esferas municipais ainda s?o fr?geis e despreparadas para enfrentar a preserva??o de conjuntos mais complexos.

Searchs discuss the function of the law like as a induction in the territorial occupation, and the conduction urban planning. Wants to understand why the disordered occupation occurs intensely on the fringes of legality in areas with legal restrictions on their occupation. These areas with specific legal restrictions are often occupied by informal settlements, with different patterns of income and, ultimately, by virtue of legal restrictions remain on the fringe of the city's legal benefits, deepening the process of environmental degradation, social and urban development. Takes as a case study the city of Suzano/SP, which has part of its territory that is inserted into the protection area of the watershed (73%), Tiet?

The urban segregation, the move towards the outskirts, the intense migratory flow and the physical conurbation among the towns, affect mainly the appropriation of their public spaces. Considering such transformations and the growing loss of the public way of living in the cities, as well as the urban and buildings patrimony, it is in the public spaces where the importance of the identity preservation and the social contacts are observed. The public spaces are also an essential element for the urban centers re-qualification, for they are being depleted from their civic and recreational functions, due to historical processes of real estate speculation and space segregation. Through research, surveys and comparative analyses of actual data about the Valinhos municipality s public spaces with patrimonial value, it is intended to investigate the main transformations and impacts that these spaces experienced with the continuous and disperse onward march of the urbanization process and the devaluation of the original urban fabric. / As cidades que comp?em a Regi?o Metropolitana de Campinas v?m sofrendo nas ?ltimas d?cadas com o processo de regionaliza??o e metropoliza??o das atividades, tendo conseq??ncias na estrutura??o de seu tecido urbano e na organiza??o de sua popula??o.

Also, the cost associated with the carbon sequestration service was calculated and how much the municipality would benefit from creating a market for the carbon credits generated in the reforestation projects in these areas. It was shown that the commercialization of credits would cover up to 46% of the project implementation costs. In addition to carbon sequestration, the recovery of PPAs along watercourses provides additional ecosystem services to the municipality, which if contemplated in the cost-benefit analysis of reforestation projects represent the largest portion of the total benefits. Therefore, the inclusion of the benefits generated by the additional ecosystem services has proved to be fundamental to make the recovery of PPAs economically viable. / Este trabalho apresenta o potencial de fixacao de carbono e provisao de demais servicos ecossistemicos das Areas de Preservacao Permanente ao longo dos cursos d?agua do municipio de Campinas-SP. Ainda, calculou-se o custo associado ao servico de fixacao de carbono e o quanto o municipio se beneficiaria ao criar um mercado para os creditos de carbono gerados nos projetos de reflorestamento destas areas. Foi demonstrado que a comercializacao dos creditos cobriria ate 46% dos custos de implantacao dos projetos. Alem da fixacao de carbono, a recuperacao das APPs ao longo de cursos d?agua proporciona servicos ecossistemicos adicionais ao municipio, e que se contemplados na analise custo-beneficio dos projetos de reflorestamento representam a maior porcao dos beneficios totais. Portanto, a inclusao dos beneficios gerados pelos servicos ecossistemicos adicionais mostrou-se fundamental para tornar a recuperacao das APPs economicamente viavel.

Esta Tesis se enmarca dentro del estudio de las aplicaciones lineales entre subespacios de funciones continuas definidas en espacios métricos y que toman valores en espacios normados. En concreto, el Capítulo 1 está dedicado al estudio de las aplicaciones separadoras entre espacios de funciones absolutamente continuas. En el Capítulo 2 consideramos aplicaciones biseparadoras definidas entre espacios de funciones de Lipschitz. Por otro lado, las isometrías entre espacios de funciones de Lipschitz se estudian en el Capítulo 3 y, finalmente, analizaremos las aplicaciones que preservan ceros comunes entre ciertos subespacios de funciones continuas que incluyen, entre otros, los mencionados anteriormente.Así, nuestro objetivo es proporcionar algunos resultados acerca de la representación de las aplicaciones lineales consideradas. Además, observamos que la continuidad de las aplicaciones biseparadoras y de las que preservan ceros comunes se puede deducir de manera automática bajo ciertas condiciones. / In this Thesis we deal with linear maps between subspaces of continuous functions defined on metric spaces and taking values in normed spaces. In particular, the Chapter 1 is devoted to study separating maps between spaces of absolutely continuous functions. In Chapter 2 we consider biseparating maps between Lipschitz function spaces. On the other hand, the isometries between spaces of Lipschitz functions are studied in Chapter 3 and, finally, we consider maps preserving common zeros between some subspaces of continuous functions, which include the subspaces given above.Therefore, our aim is providing some results about the representation of each linear map that we consider in this Thesis. Besides, the automatic continuity of biseparating maps and maps preserving common zeros is derived in some cases.

This fact has been perpetuated during years and added the current social found problems in the large cities and contributed for the environmental degradation caused by irregular nestings. The Environmental Sensible Areas vary between environmental interests to risk areas. Beyond the predatory occupation of the urban spaces with intense urbanization without planning, the precarious nestings also contribute with the alteration of the vegetation, of the ground, hydro resources and even in the change of the microclimate, becoming also a risk to the health and the physical-mental integrity of the there resident population. These urban inadequacy must be prevented and avoided, reparable and compensatory measures with adjusted technologies must be adopted to solve the diverse problems of degradation. Ahead of such situation, it is necessary to know the public politics, especially the habitation ones, directed to equate the deriving problems of occupations and the programs and techniques of urban and environmental recovery. The city of Campinas, studied region, has similarities with other regions of Brazil, with innumerable nestings also in Environmental Sensible Areas, being, therefore, a representative case. / Ao longo da hist?ria do urbanismo brasileiro, observamos a aus?ncia do Estado com medidas mais eficazes para atender ? demanda por habita??o.
