Modernizing Mount Royal Park : Montréal’s Jungle in the 1950s

Caron, Matthieu 02 1900 (has links)
Durant les années 1950, les autorités municipales, sous la pression du département de la police, ont demandé le déboisement d’une section du parc du Mont-Royal. Cette section, communément appelée la « Jungle » et principalement composée de broussailles, de buissons et d’arbres, était fréquentée par une clientèle considérée comme indésirable. Cette dernière comprenait, essentiellement, des alcooliques, des voyous, des pervers, et, surtout, des homosexuels. Leur éradication s’est alors déployée selon un plan en trois étapes qui avait pour objectif de simplifier les techniques de surveillance utilisées par le département de la police. D’abord, une augmentation de l’éclairage, puis, le déboisement de la « Jungle », et, finalement, la construction d’une route, aujourd’hui connue sous le nom de Camillien-Houde. Le parc devenait ainsi plus accessible et plus sécuritaire. Les coupes, que l’on a appelées les « coupes de la moralité », ont eu un effet considérable sur l’environnement et la composition écologique du parc, donnant, entre autres, aux Montréalais, l’impression que le parc était devenu chauve (ce qui lui conféra d’ailleurs le surnom de Mont Chauve). Les transformations du parc du Mont-Royal n’étaient cependant pas limitées à sa Jungle. En fait, des modifications furent aussi mises en application dans d’autres sections considérées comme sous-développées. La métamorphose du parc et de sa « Jungle » était un acte de développement caractéristique de l’ère moderniste de la planification du Montréal d’après-guerre. La re-planification du parc du Mont-Royal témoigne ainsi d’une volonté sans bornes des autorités d’instaurer la moralité et la modernité dans la ville, volonté qui aura pour conséquence d’altérer la composition écologique du parc. C’est ce qui sera à l’origine d’une campagne nommée « Save-the-Mountain Movement », qui a cherché à empêcher la modernisation de l’espace et milité pour la réhabilitation du parc en tant que boisé paisible. / During the 1950s, the municipal authorities, under pressure from the Police Department, called for the clearing of a section of Mount Royal Park—the so-called “Jungle” (composed mainly of undergrowth, bushes, and trees)—where a community of undesirable Park patrons had established themselves. This cohort of undesirables was understood as being composed mainly of alcoholics, thugs, perverts and most importantly homosexuals. Their eradication was undertaken through a threefold plan which would simplify the techniques of surveillance used by the Police Department; this would be achieved through (1) increased lighting, (2) clearing the Jungle, (3) construction of a roadway, now known as the Camillien-Houde roadway, thus making the Park more accessible and safe. The cuts, known as the Morality Cuts, had a lasting effect on the environmental and ecological composition of the Park, with the immediate repercussion of “balding” the Park, thereby giving it the nickname of Mount Baldy. Yet Mount Royal Park’s transformation was not limited to its Jungle. In fact, the transformation was undertaken in a number of the Park’s sections which were deemed undeveloped. The development Mount Royal Park and of its Jungle were therefore acts of development, under the umbrella of Montréal’s modernist postwar planning. Indeed, the re-planning of Mount Royal Park testifies to the unbounded will of the authorities to instill morality and modernity within the city, going to lengths that ultimately altered the ecological composition of the Park. This would in the end lead to an all out campaign named the Save-the-Mountain Movement, which sought to end the modernist encroachment of this space and rehabilitate the Park as a wooded and tranquil environment.

Caminho velho das Minas Gerais: uma análise das transformações sócio-ambientais da fronteira de colonização do século XVIII / The old path to Minas Gerais: an analysis of XVIII century socio-ecological transformations of colonized frontiers in Brazil

Alexia Helena de Araujo Shellard 11 April 2013 (has links)
Fundação de Amparo à Pesquisa do Estado do Rio de Janeiro / Natureza é uma idéia complexa forjada na tradição ocidental de oposição entre espírito e matéria; a natureza, contudo, comporta não apenas significados biofísicos, mas também dimensões míticas e evocativas. Baseada nessa perspectiva, a presente dissertação analisa as transformações ambientais que ocorreram na esteira da colonização das Minas Gerais através do Caminho Velho. Estudando aspectos simbólicos, econômicos e ecológicos do processo de ocupação dos sertões, tentamos compreender os distintos elos materiais e imateriais que conectam seres humanos e espaço. O ouro atraiu para o interior da América portuguesa multidões de pessoas que necessitavam alimento e abrigo. Se a existência do ouro pode ser considerada um fator físico, o que dizer da valorização do metal pelas populações européias? Se o alimento é uma necessidade fisiológica para a sobrevivência humana, o que pensar da preferência de garimpeiros por carne de boi? Traçando relações entre fisicalidade e cultura, evidenciamos as transformações como resultado do dialogismo entre sociedade e natureza. A natureza dos sertões mineiros ao longo de um século foi totalmente alterada: milhares de espécies nativas foram substituídas por algumas poucas espécies exóticas. A agência humana teve um papel crucial nessa revolução, mas o imperialismo ecológico, embora impulsionado pelo expansionismo europeu, não rendeu exatamente os frutos ansiados pelos colonizadores.

A QUEST FOR ENVIRONMENTAL SOVEREIGNTY : Chicana/o Literary Experiences of Water (Mis)Management and Environmental Degradation in the US Southwest

Perez-Ramos, María Isabel January 2017 (has links)
The U.S. Southwest is a semi-arid region affected by numerous environmental problems. Chicana/o communities have been directly affected by such problems, especially ever since the region was annexed from Mexico by the United States in the mid-nineteenth century. From this moment onwards they lost their environmental sovereignty, mostly through their dispossession of the natural resources.   This environmental humanities dissertation focuses on the ethics, politics, and practices around water (management), for water is a key natural resource and a central element of Chicana/o cultural identity. It explores the ways in which Chicana/o culture is interconnected with environmental practices and sites in subaltern literary works about the Chicana/o experience. It investigates how the hegemonic Anglo-American environmental, political, and economic practices have challenged and undermined Chicana/o culture, identity, and wellbeing, and how this has been addressed in fiction; and it questions whether establishing such a connection adds any useful insights to the larger discussion on the global socio-environmental crisis. This dissertation also analyzes the writer activist character of the subaltern narratives of the corpus, with attention to the relevance of rhetoric in subverting and constructing environmental discourses and ethics.   By examining regional and border narratives, as well as fiction and non-fiction narratives about the socio-environmental struggles of other ethnic minorities in the Southwest and in other parts of the world, this dissertation puts literature about the Chicana/o experience in a regional, national, and transnational context. It moreover explores the pivotal role of literature in reclaiming environmental sovereignty, in asserting cultural identities, and in countering the environmental crisis by imagining alternative managerial practices and socio-environmental relations, as much as in challenging cultural hegemonies. / <p>QC 20170508</p>

A History under Siege : Intensive Agriculture in the Mbulu Highlands, Tanzania, 19th Century to the Present

Börjeson, Lowe January 2004 (has links)
This doctoral thesis examines the history of the Iraqw’ar Da/aw area in the Mbulu Highlands of northern Tanzania. Since the late nineteenth century this area has been known for its intensive cultivation, and referred to as an “island” within a matrix of less intensive land use. The conventional explanation for its characteristics has been high population densities resulting from the prevention of expansion by hostility from surrounding pastoral groups, leading to a siegelike situation. Drawing on an intensive programme of interviews, detailed field mapping and studies of aerial photographs, early travellers’ accounts and landscape photographs, this study challenges that explanation. The study concludes that the process of agricultural intensification has largely been its own driving force, based on self-reinforcing processes of change, and not a consequence of land scarcity.

Guld och gröna skogar? : miljöanpassningen av Rönnskärsverken 1960-2000

Bergquist, Ann-Kristin January 2007 (has links)
The aim of this thesis is to reach further understanding of the development of environmental adaptation in Swedish heavy industry by studying the case of the Rönnskär Smelter 1960-2000. More specifically, the aim of the thesis is to investigate the interplay between firm level environmental adaptation and national environmental politics and economic development. To fulfil this aim, the following questions are asked: How have company activities such as production processes, organisation and company strategies been developed and adopted in order to meet environmental demands with maintained competitiveness? How have company activities been framed by environmental policies and the specific environmental regulations, relevant for this case? What other factors, beside environmental regulations, have driven and framed the environmental adaptation process of the firm? The study concludes that a long-range competitive environmental adaptation was reached by a combination of investments in environmental technology with an overall rationalisation and modernisation of the enterprise. The study suggests that the environmental adaptation process of the Rönnskär Smelter became part of an overall process of industrial modernisation during the period, which reflects a wider context than the environmental issue itself. It mirrors technological development on other fields than the environment, and an increasing competition on a global scale that called for lower unit costs of production. This led to a modernisation for pollution reduction strategy that enabled the firm to increase production but still cutting its pollution levels considerably over time. The result is partly consistent with the Porter hypothesis that suggests that strict environmental regulation can strengthen firms’ and nations’ competitiveness. Time series data shows that emissions from the Rönnskär factory have radically declined since the 1960s. For these changes, process technology has proven to be most important. Technological adjustments came about through a step-by-step adaptation. It is clear that internal solutions, developed by the companies’ own engineers were more important at an early stage, when the supply of external solutions was limited. The study also concludes that environmental regulation has strongly influenced the environmental adaptation at the Rönnskär Smelter. Of most importance is the Environmental Protection Act (EPA: Miljöskyddslagen) implemented in 1969. In the economic historian Nathan Rosenberg’s terminology, this study suggests that the EPA model of individual testing promoted long-term innovative and cost-effective technical solutions, because it was consistent with decentralised experimental activity and the specific conditions that characterise the dynamics of technological development. However, not much can be said before comparative studies within the Swedish system have been conducted, or perhaps most fruitful, between various national systems of environmental protection. This study also concludes that the environmental issue became of strategic dignity at the very beginning of the 1970s, mainly as a consequence of the implementation of the EPA. Even though environmental issues did not become important for market strategies until the 1990s, the environmental issue called already in the 1970s for adjustments that required financial and personnel resources that demanded priorities and strategic decisions at the highest level of the organisation. The study also concludes that even though the technological dimension has played the most decisive role for lowering emissions, the significance of organisation has increased over time. While the 1960s, and especially the 1970s, brought about substantial pollution reductions through new technology, organisational aspects became relatively more important when the costs of abatement were rising in the 1980s. Organisational co-ordination, division of local responsibilities and education of personnel became a supplement to technology to obtain further pollution reductions. The technician as the “environmental hero” of the firm was successively replaced by the organisational co-ordinator.

Undercurrents of urban modernism : water, architecture, and landscape in California and the American West

Faletti, Rina Cathleen 01 September 2015 (has links)
"Undercurrents of Urban Modernism: Water, Architecture, and Landscape in California and the American West" conducts an art-historical analysis of historic waterworks buildings in order to examine cultural values pertinent to aesthetiteics in relationships between water, architecture and landscape in the 19th and early 20th centuries. Visual study of architectural style, ornamental iconography, and landscape features reveals cultural values related to water, water systems, landscape/land use, and urban development. Part 1 introduces a historiography of ideas of "West" and "landscape" to provide a context for defining ways in which water and landscape were conceived in the United States during turn-of-the-century urban development in the American West. Part 2 provides a historical context for California waterworks with a discussion of major U.S. city waterworks from 1799 to 1893 in Philadelphia, Louisville, New York, and New Orleans. Primary architectural styles discussed are Greek Revival, Egyptian Revival, and Roman Revival. Part 3 presents the dissertation's central object of study: waterworks and hydropower architecture for the greater San Francisco Bay Area between 1860 and 1939. From substations to dams, architects who designed waterworks structures drew from historical revival, academic eclecticism, and structural design traditions. The specific waterworks structures anchoring inquiry in this chapter are two round, peripteral, neoclassical water temples built for San Francisco's water supply to mark key underground aqueduct features. I analyze these two temples--the Sunol Water Temple from 1910 and the Pulgas Water Temple from 1939--in formal terms as well as from within broader urban and historical contexts. Part 4 culminates the dissertation with a case study of two dams whose aesthetic features were obscured by unneeded buttresssing when concerns for dam safety arose after a Southern California dam failure had killed several hundred people in 1928. I inquire into a cultural ambivalence stemming that seems to stem from historical conflicts determining the relative aesthetics of "use" and "beauty" in utilitarian waterworks structures. The overall questions in this dissertation inquire into ways in which aesthetic aspects of architectural design of waterworks structures expressed cultural values regarding water, architecture, and landscape in California between 1860 and 1939. / text
