Fundamentos jurídicos do meio ambiente criado e os principais instrumentos de proteção do patrimônio ambiental cultural material

Boch, Queli Mewius 01 April 2011 (has links)
O meio ambiente cultural, composto de natureza e cultura, é parte integrante do direito ambiental, e sua proteção caracteriza-se como direito constitucional fundamental de todo cidadão, vez que visa a manter viva a história e identidade de um povo, evitando dissipar a geração antecedente daquelas que ainda estão por vir. A preservação do patrimônio ambiental cultural pode ser considerada como o direito à preservação do meio ambiente cultural, que é meio para a garantia da sadia qualidade de vida humana. Os valores que retratam a proteção do patrimônio ambiental cultural estão presentes no ordenamento jurídico brasileiro, com previsão constitucional, infraconstitucional e legislações esparsas, com caráter nacional e internacional, voltadas à proteção desse patrimônio de forma abrangente. A tutela do patrimônio ambiental cultural, que porta referência à ação, à memória e à identidade do povo brasileiro, encontra guarida nos principais instrumentos jurídicos de tutela administrativa e judicial dos bens culturais, bem como naqueles de ordem local, regulamentados no Estatuto da Cidade e executados pelo Plano Diretor Municipal, os quais buscam tutelar e fiscalizar a proteção que faz jus o patrimônio cultural, mantendo preservado o meio ambiente cultural, histórico e paisagístico de uma comunidade, resguardando suas memórias históricas, suas origens, seus costumes e, em especial, sua identidade. A preservação do meio ambiente histórico e cultural de uma localidade, cidade ou região, deve ser incentivada na atual sociedade, pela própria comunidade local, que deverá reconhecer o valor intrínseco de cada bem que pretende ver preservado, bem como mediante políticas públicas que visem não deixar cair no esquecimento a história do povo que a colonizou, evitando dissipar a memória da geração antecedente. / The cultural environment, consisting of nature and culture, is an integral part of environmental law and its protection is characterized as a fundamental constitutional right of every citizen, as it seeks to keep alive the history and identity of a people, preventing the absorption of previous generation from those who are yet to come. The preservation of cultural heritage environment can be considered as the right to preservation of cultural environment, which is the way to guarantee healthy quality of life. The values that reflect the cultural heritage protection environment are present in Brazilian law, with constitutional and infra-constitutional provision and sparse legislation, with national and international character, that aim to protect this heritage in a comprehensive manner. The preservation of the cultural heritage environment, which carries a reference to action, memory and identity of the Brazilian people, find shelter in the main legal instruments for administrative and judicial protection of cultural property, as well as those of local order, regulated by the Statute of the City and performed by the Municipal Master Plan, which seek to protect and enforce the protection that lives up the cultural heritage preserved by keeping the cultural environment, history and landscape of a community, protecting its historic memories, their origins, their habits and, in particular, their identity. The preservation of historic and cultural environment of a city, town or region should be encouraged in today´s society, by the local community itself, which should recognize the intrinsic value of each item you want to see preserved as well as through public policies that do not allow the history of the colonized people to be forgotten, avoiding dispel the memory of the previous generation.

À l'ombre de la montagne : le paysage archéologique du versant nord du mont Royal, Montréal, 1698-1900

Janssen, Valérie 02 1900 (has links)
Ce mémoire s’inscrit dans un projet de recherche plus global sur l’évaluation du potentiel archéologique du mont Royal réalisé par l’Université de Montréal en partenariat avec la Ville de Montréal et le ministère de la Culture et des Communications du Québec. Plus précisément, il a pour objectif de mettre en œuvre et d’apporter une réflexion sur l’outil dans la gestion du patrimoine archéologique. Au Québec, malgré l’importance de cet outil à l’étape du diagnostic en archéologie préventive, il existe peu de connaissances empiriques sur son efficacité et sur la validité des différentes méthodologies employées. Nous avons donc voulu mieux comprendre la démarche de l’évaluation du potentiel à partir de l’approche du paysage culturel et de celle de l’écologie historique, et ce, afin de voir comment cela pouvait apporter une nouvelle façon d’envisager le potentiel archéologique. L’élaboration de notre cadre théorique s’est appuyée, notamment, sur une trentaine d’études de potentiel archéologique produite au Québec. À l’aide de ce cadre théorique, le potentiel archéologique du versant nord du Mont-Royal a été documenté sur une période allant de la fin du XVIIe siècle jusqu’au XXe siècle. La recherche théorique a été complétée par des inspections visuelles des zones, permettant ainsi de documenter plus finement certains éléments environnementaux, tels la topographie, le couvert végétal, l’hydrographie, etc. Dans la construction du paysage culturel, c’est l’aspect mythique et symbolique de la montagne qui nous intéresse. Nous en avons retenu trois thèmes principaux qui s’échelonnent dans le temps, c’est-à-dire la montagne pittoresque et le paysage forestier, la montagne agricole et l’industrie des tanneries et, enfin, l’arrivée des cimetières et des établissements religieux. Pour chacun de ces thèmes, des orientations de recherche sont énoncées en guise de réflexion sur les éléments d’intérêt archéologique présentés. Ces thèmes, nous le suggérons, pourront être pris en compte dans un contexte d’archéologie préventive. / This thesis is part of a broader research project on the archaeological potential of Mount Royal carried out by Université de Montreal in partnership with the City of Montreal and the Ministry of Culture and Communications of Quebec. More specifically, it aims to assess the utility and efficiency of archaeological potential studies as a tool in cultural resource management. In Quebec, despite the importance of this tool in preventive archaeology at the diagnostic stage, there has been very little empirical study of its effectiveness and the validity of the different methodologies used. We therefore wish to bring a better understanding to the assessment of archaeological heritage potential by using a cultural landscape and historical ecology approach, in order to see how this can bring about a new way of considering archaeological potential. The development of the theoretical framework for this paper was based on some thirty archaeological assessments produced in Quebec. It is through this theoretical framework that the archaeological potential of the territory under study, namely the northern slopes of Mount Royal, was documented for a period starting at the end of the 17th century up to the 20th century. The theoretical research was complemented by visual inspections of the geographical zones, thereby permitting a more precise documentation of certain environmental features such as the topography, the ground vegetation and tree cover, the hydrography, etc. In the construction of the cultural landscape, the mythical and symbolic aspects of the mountain retain our interest. We have chosen three main themes, namely the picturesque mountain and the forest landscape, the agricultural mountain and the tanning industries and, lastly, the arrival of cemeteries and religious institutions. For each theme, research orientations are formulated in order to reflect the elements of archaeological interest that we present. These themes may be taken into account for archaeological resource management.

Tables de concertation et préservation du patrimoine, solution porteuse ou chimère ? : deux cas d’étude, le Vieux-Montréal et le mont Royal

Krim, Nacéra 05 1900 (has links)
La concertation est un phénomène récent, de plus en plus répandu. Elle s’applique à de nombreux domaines notamment en urbanisme et plus récemment à la protection du patrimoine. Elle semble être un outil approprié pour les autorités municipales afin de faire face aux conflits autour des projets d’aménagement particulièrement ceux liés à la protection du patrimoine. Notre questionnement porte sur l’apport de la concertation dans le domaine de la préservation du patrimoine et sur la pertinence des moyens mis en place pour atteindre un tel objectif. Les tables de concertation, en tant que processus de concertation, sont-elles appropriées pour la gestion des sites patrimoniaux ? À la lumière d’une discussion théorique sur le concept de la concertation en aménagement, nous faisons l’analyse comparative de deux Tables de concertation, celle du Vieux-Montréal et celle du Mont-Royal. Notre analyse porte sur l’évaluation du processus de concertation et sur la construction d’une vision globale pour le devenir des secteurs patrimoniaux concernés. L’objectif est de caractériser le processus de concertation utilisé à Montréal et d’en apprécier l’apport dans le domaine de la protection du patrimoine. L’analyse de nos deux cas d’étude révèle l’existence d’un processus de concertation propre à Montréal, avec ses caractéristiques spécifiques, mais qui reste à parfaire pour son optimisation. Notre recherche se conclut sur la nécessité d’améliorer le processus de concertation, tel qu’étudié, à travers un certain nombre de pistes à explorer. / Consensus building is a recent and increasingly widespread phenomenon. It is used in many areas, including urban planning, and more recently heritage protection. Consensus building appears to be an appropriate tool for municipal authorities to handle conflicts in development projects, especially those projects that are related to heritage protection. Our research focuses on the contribution of consensus building in the area of heritage preservation, and on the means put in place to achieve such a goal. Are round tables, as part of the consensus building process, appropriate in managing heritage sites? Based on a theoretical discussion on consensus building in development issues, we compare two case studies, namely the Old Montréal and the Mount Royal round tables on consensus building. This analysis focuses on assessing the consensus building process and on developing a global vision for the future of the two heritage sectors under study. Our goal is to characterize the consensus building process used in Montréal and to evaluate its contribution to the field of heritage protection. The analysis of our two case studies reveals the existence of a distinctive consensus building process specific to Montréal, a process which however needs to be optimized. We conclude our research with the need to improve the assessed consensus building process through a number of avenues to explore.

Coopération internationale et protection du patrimoine au Laos : analyse du programme UNESCO-Chinon-Luang Prabang à la lumière des Policy transfer studies / International cooperation and heritage protection in Laos : analysis of the UNESCO-Chinon-Luang Prabang program in the light of the policy transfer studies

Sisaykeo, Phimpha 18 December 2015 (has links)
La coopération au développement met en jeu de puissantes forces de changement et de résistance à l’interface de systèmes d’acteurs paramétrés culturellement, économiquement, politiquement et institutionnellement de manières souvent très différentes. Des demandes d’assistance sont émises et des offres de service sont proposées sur des problèmes pour lesquels doivent être bâties des réponses adaptées aux situations pour lesquelles elles ont été sollicitées. Comment se construisent ces réponses ? Comment sont prises en compte les spécificités des acteurs ? Comment sont intégrées les caractéristiques culturelles, économiques, politiques et institutionnelles des partenaires lorsque ceux-ci se retrouvent en situation d’altérité significative ? Comment finalement s’élabore une solution de développement en coopération ? Ce travail propose des éléments de réponse à partir de la coopération à la protection du patrimoine entre Luang Prabang, Chinon et l’UNESCO de 1995 à 2015 et la mobilisation d’un protocole de recherche dont les principaux outils sont empruntés aux analyses en termes de transfer studies. / The development cooperation brings into play powerful forces of change and resistance at the interface of different culturally, economically, politically and institutionally systems of actors. Requests for assistance are emitted and services offerings are proposed on problems for which must be built answers adapted to situations for which they are requested. How are these answers built ? How are taken into account specificities of the actors ? How are integrated the partners cultural, economic, political and institutional characteristics in situation of significant otherness ? Finally, how is a solution of development in cooperation worked out ? This research proposes replies starting from the cooperation to heritage protection between Luang Prabang, Chinon and UNESCO from 1995 to 2015, and the mobilization of a protocol of research whose principal tools are borrowed from the analyses in terms of transfer studies.

Stadtplanung in der zweiten Hälfte des 20. Jahrhunderts am Beispiel Dresdens

Lerm, Matthias 30 June 2011 (has links)
Gegenstand der Habilitationsschrift sind die wesentlichen Strömungen der städtebaulichen Entwicklung Dresdens in der zweiten Hälfte des 20. Jahrhunderts. Der Zeitraum umfasst Planungen und Realisierungen zwischen der Zerstörung Dresdens am 13./14. Februar 1945 und der Vereinigung mit der Bundesrepublik Deutschland am 3. Oktober 1990. Wichtige Etappen bilden dabei die Konzeptionssuche nach der Zerstörung, der Städtebau der „nationalen Tradition“, die Rückbesinnung auf die Konzepte der Moderne, die Generalbebauungs- und Generalverkehrsplanung, das Wohnungsbauprogramm und die Wiederentdeckung des innerstädtischen Bauens. Aspekte der städtebaulichen Entwicklung Dresdens vor 1945 mit dem Schwerpunkt der 30er und frühen 40er Jahre des 20. Jahrhunderts sowie im wiedervereinigten Deutschland nach 1990 wurden ergänzend einbezogen. Die Schrift besteht aus einem Einführungstext, der die Dresdner Entwicklung in die städtebaulichen Leitbilder einordnet, und dem Hauptteil mit Auszügen aus 33 wissenschaftlichen Veröffentlichungen des Autoren über den gesamten Betrachtungszeitraum hinweg. Neben der städtebaulichen Entwicklung insgesamt wird auch auf Teilaspekte wie Wohnungsbau, Verkehrsentwicklung oder die Leitbilddiskussion eingegangen. Der breite Katalog der städtebaulichen Lösungen, in mehreren Jahrzehnten und über Paradigmenwechsel hinweg entstanden, bildet einen wertvollen Erfahrungsschatz. Vor allem der Aspekt der Besonderheit der städtebaulichen Entwicklung Dresdens, der Radikalität, aber auch Beschränktheit der vielfach gewählten Lösungen, stellt im Sinne einer Bestandsaufnahme einen wesentlichen Ausgangspunkt für jegliche gegenwärtige und zukünftige Auseinandersetzung mit dem physischen Körper der Stadt dar. Einerseits wird es erleichtert, schutzwürdige Qualitäten der städtebaulichen Entwicklung des behandelten Zeitraumes zu erkennen, andererseits werden aber auch Ansatzpunkte für eine zukunftsfähige künftige Stadtentwicklung geboten. / The subject of this study (Habilitation) is Dresden’s city planning in the second half of the twentieth century and the main strands of its development. The time frame comprises planning and realizations of building projects between the destruction of Dresden on 13/14 February 1945 and German reunification on 3 October 1990. Important stages are the search for planning concepts after destruction, projects of the “national tradition”, rediscovery of Modernist concepts, general city and transport plans, the programme for housing and the further development of inner-city planning. Additionally included are aspects of planning development before 1945 – with an emphasis in the 1930s and early 40s – as well as the situation in reunified Germany after 1990. The study consists of an introduction, which places Dresden’s development within planning paradigms. The middle section is a compilation of extracts from the author’s 33 scholarly publications spanning the entire time frame of this study. Apart from planning history in general, the study also considers housing, transport and theoretical discussions. The rich catalogue of planning solutions, acquired over decades and across changes in paradigms, builds a valuable store of experience. Especially through the uniqueness of Dresden‘s planning history, the radicalism, but also often the narrowness of chosen solutions, compiled here as a first inventory, a vital starting point for any current and future engagement with the body of this city is formed. On the one hand, the study facilitates the identification of the qualities that are worth preserving; on the other, suggestions for future-oriented city planning are offered.

Estudio y caracterización de las estructuras laminares de hormigón armado en la Comunitat Valenciana

Arnau Paltor, Fernando Amadeo 13 October 2021 (has links)
[ES] Las láminas de hormigón armado utilizan principalmente su forma como meca-nismo resistente. Son estructuras extremadamente eficientes y bellas. El desarrollo de este tipo de estructuras se inicia en torno a los años 20 del siglo XX alcanzando su esplendor cuantitativo y cualitativo en torno a los años 50 y 60. Su ocaso les llega en las décadas siguiente, fundamentalmente por motivos económicos. Su breve período de existencia hace que los ejemplos que tenemos de esta tipología sean muy limitados. Por cuestiones relativas a la durabilidad del hormigón armado, la protección de este singular patrimonio arquitectónico resulta necesaria y urgente, de modo especial en la Comunitat Valenciana (España) con un clima costero con cloruros agresivos para las estructuras de hormigón, especialmente para aquellas de escaso espesor y por lo tanto reducido recubrimiento del armado. El presente estudio pretende la caracterización histórica, constructiva y estructural de las estructuras laminares de hormigón armado en la Comunitat Valenciana. Para ello se ha realizado una labor previa de localización y documentación de die-cisiete estructuras para su completa catalogación. El objetivo final es la divulgación y puesta en valor, de esta tipología estructural en la Comunitat Valenciana con la esperanza de que administraciones y propietarios emprendan acciones para su conservación, rehabilitación y protección. Con su puesta en común podemos estudiar los distintos tipos de subcategorías de esta tipología, sus características comunes y diferenciadoras, el contexto histórico de su aparición, la evolución de su tecnología constructiva a lo largo de la historia, comparar los problemas que han afrontado en las fases de proyecto y ejecución o las lesiones que han sufrido a lo largo de su vida útil de cara a la prevención necesaria para una adecuada conservación. En la segunda parte de este trabajo, basada en tres artículos publicados, se estudia en detalle de la iglesia de San Nicolás del Grao de Gandía (España), de modo que sirva como primer paso para posteriores estudios en profundidad de los otros ejemplos de láminas en la Comunitat Valenciana. La iglesia de San Nicolás de Gandía (1962) es la obra póstuma del prestigioso ingeniero Eduardo Torroja Miret (1899-1961) en colaboración con el arquitecto Gonzalo Echegaray Comba y el ingeniero Jaime Nadal Aixalá. Torroja, fue pionero en el uso del hormigón pretensado, utilizándolo de modo variado e ingenioso en muchas de sus obras. Esta tecnología le permitió conseguir el estado tensional adecuado en el hormigón a la vez que garantizar su estanqueidad. Su intuición y experiencia le llevaron a asesorar en el desarrollo del método de tesado y anclaje patentado como "Método Barredo". La estructura de la iglesia de San Nicolás consiste en dos láminas plegadas de hormigón armado apoyadas en los pórticos testeros del edificio. Se trata de una solución innovadora, para salvar una luz de 29 m. El comportamiento de las láminas fue mejorado mediante una serie de costillas de rigidización y un sistema de tendones postesados que permitió minimizar los efectos de flexión esviada derivados de la sección asimétrica de dichas láminas. Los valores obtenidos de dos modelos informáticos de elementos finitos muestran una buena correspondencia con los cálculos realizados a manos por el ingeniero, reafirmando su excelente intuición estructural. Los resultados ayudan a comprender el funcionamiento de esta ingeniosa y compleja estructura. En 1996 se realizó un estudio detallado de la patología constructivas presentes en la iglesia, especialmente fisuras y desprendimiento del recubrimiento de hormigón por corrosión de las armaduras. Se describen también las lesiones presentes en el edificio y el proyecto y obras de rehabilitación que comenzaron en el año 2001 y culminaron en el año 2012, 50 aniversario de la iglesia. / [CA] Les làmines de formigó armat utilitzen principalment la seva forma com a mecanisme resistent. Són estructures extremadament eficients i belles. El desenvolupament d'aquest tipus d'estructures s'inicia al voltant dels anys 20 de segle XX aconseguint els seus any daurats quantitatius i qualitatius al voltant dels anys 50 i 60. El seu ocàs comença a la dècada següent, fonamentalment per motius econòmics. El seu breu període d'existència, és causa de que els exemples que tenim d'aquesta tipologia siguin molt limitats. Per qüestions relatives a la durabilitat del formigó armat, la protecció d'aquest singular patrimoni arquitectònic resulta necessària i urgent, de manera especial a la Comunitat Valenciana (Espanya) amb un clima de costa amb clorurs agressius per a les estructures de formigó, especialment per a aquelles d'escàs gruix i per tant reduït recobriment de l'armat. El present estudi pretén la caracterització històrica, constructiva i estructural de les estructures laminars de formigó armat a la Comunitat Valenciana. Per a això s'ha realitzat una tasca prèvia de localització i documentació de disset estructures per a la seva completa catalogació. L'objectiu final és la divulgació i posada en valor, d'aquesta tipologia estructural a la Comunitat Valenciana amb la esperança que administracions i propietaris emprenguin accions per a la seva conservació, rehabilitació i protecció. Amb la seva posada en comú podem estudiar els diferents tipus de subcategories d'aquesta tipologia, les seves característiques comunes i diferenciadores, el context històric de la seva aparició, l'evolució de la seva tecnologia constructiva al llarg de la història, comparar els problemes que han afrontat en les fases de projecte i execució o les lesions que han patit al llarg de la seva vida útil de cara a la prevenció necessària per a una adequada conservació. A la segona part d'aquest treball, basada en tres articles publicats, s'estudia en detall de l'església de Sant Nicolau del Grau de Gandia (Espanya), de manera que serveixi com a primer pas per a posteriors estudis en profunditat dels altres exemples de làmines a la Comunitat Valenciana. L'església de Sant Nicolau de Gandia (1962) és l'obra pòstuma de el prestigiós enginyer Eduardo Torroja Miret (1899-1961) en col·laboració amb l'arquitecte Gonzalo Echegaray Comba i l'enginyer Jaime Nadal Aixalá. Torroja, va ser pioner en l'ús del formigó pretesat, utilitzant-lo de manera variada i enginyosa en moltes de les seves obres. Aquesta tecnologia li va permetre aconseguir l'estat tensional adequat en el formigó a l'hora que garantir la seva estanquitat. La seva intuïció i experiència van portar a assessorar en el desenvolupament del mètode de tesat i ancoratge patentat com "Mètode Barredo". L'estructura de l'església de Sant Nicolau consisteix en dues làmines plegades de formigó armat recolzades en els pòrtics extrems de l'edifici. Es tracta d'una solució innovadora, per salvar una llum de 29 m. El comportament de les làmines és millorat mitjançant una sèrie de costelles de rigidització i un sistema de tendons posttesats que va permetre minimitzar els efectes de flexió esviada derivats de la secció asimètrica d'aquestes làmines. Els valors obtinguts de dos models informàtics d'elements finits mostren una bona correspondència amb els càlculs realitzats a mà per l'enginyer, reafirmant la seva excel·lent intuïció estructural. Els resultats ajuden a comprendre el funcionament d'aquesta enginyosa i complexa estructura. El 1996 es va realitzar un estudi detallat de les patologies constructives presents a l'església, especialment fissures i despreniment de el recobriment de formigó per corrosió de les armadures. Es descriuen també les lesions presents a l'edifici i el projecte i obres de rehabilitació que van començar l'any 2001 i van culminar en l'any 2012, 50 aniversari de l'església. / [EN] Shell concrete structures mainly use their shape as a resistant mechanism. They are extremely efficient and beautiful structures. The development of this type of structures began around the 20s of the 20th century, reaching its quantitative and qualitative golden years around the 50s and 60s. Its decline came in the following decades, mainly for economic reasons. The examples we have of this typology are very few because its short period of existence . The protection of this unique architectural heritage is necessary and urgent, especially in the Valencian Region (Spain) because durability of reinforced concrete in a coast environment with chlorides floating in the air attacking reinforced concrete structures, especially for those of fewer thickness and reduced coating of the reinforcement. The present study aims at the historical, constructive and structural characterization of the reinforced concrete shell structures in Valencian Region. At this point, a preliminary task of locating and documenting seventeen structures has been carried out for their complete cataloging. The final objective is the dissemination and enhancement of this structural typology in the Valencian Region with the hope that administrations and owners will undertake actions for its conservation, rehabilitation and protection. In the catalogue are exposed the different types of subcategories of this typology, their common and different characteristics, their birth historical context, the evolution of their construction technology throughout history, compare the problems they have faced in the design and execution phases or the injuries that they have suffered throughout their useful life with a view to the prevention necessary for proper conservation. In the second part of this work, based on three published articles, the church of San Nicolás del Grao in Gandía (Spain) is studied in detail, so that it serves as a first step for later in-depth studies of the other examples of shells in Valencian Region. The church of San Nicolás de Gandía (1962) is the last work of famous engineer Eduardo Torroja Miret (1899-1961) in collaboration with architect Gonzalo Echegaray Comba and engineer Jaime Nadal Aixalá. Torroja, was a pioneer in the use of prestressed concrete, using it in diferent and ingenious ways in many of his works. This technology allowed it to achieve the desired tension state in the concrete while its tightness is guaranteed. His intuition and experience led him to advise on the development of the patented tensioning and anchoring method "Barredo Method". San Nicolás' Curch's structure consists of two folded plates of reinforced concrete supported on the extreme concrete frames of the building. It is an innovative solution for a span of 29 m. The behavior of the plates was improved by means of a series of stiffening ribs and a post-tensioned tendon system that made it possible to minimize the effects of skewed bending produced by the asymmetric section the plates. The values obtained from two finite element computer models show a good correspondence with the calculations carried out by the engineer, reaffirming his excellent structural intuition. The results help to understand how this ingenious and complex structure works. In 1996 a detailed study of the construction pathologies present in the church was carried out. cracks and detachment of the concrete coating due to corrosion of the steel reinforcements, were specially studied. The project and rehabilitation works that began in 2001 and culminated in 2012, the 50th anniversary of the church, are also described. / Arnau Paltor, FA. (2021).
