O desenvolvimento exigia muita água para suprir a demanda tanto da população ascendente quanto dos novos empreendimentos. Embora a cidade fosse servida por diversos arroios, sua capacidade de fornecer água era baixa. Poços e chafarizes não eram o suficiente, sendo obrigatória a busca por rios de maior volume d’água para construção de um sistema de abastecimento e esgoto. Durante todo o processo, da busca até a distribuição, o primeiro jornal da cidade, “O Progresso”, encarregava-se de informar a população sobre os trâmites legais, decisões da prefeitura, reclamações dos moradores, entre outras notícias da região. Para regrar a população, era preciso um Código de Posturas, o qual buscava impor certas normas necessárias para o convívio urbano e sobretudo, em tempos de expansão, evitar a proliferação de doenças. Contudo, os arroios sofreram os impactos da modernização, passaram a ser cada vez mais poluídos e vistos como carregadores de doenças. Seus cursos começaram então a ser canalizados com o intuito de mitigar o problema e levar o esgoto para longe da cidade. Para esta pesquisa, alguns moradores que viviam próximo aos arroios até a década de 1950 cederam entrevistas contando como era o ambiente durante a sua infância e juventude, suas lembranças sobre esses cursos d’água e como avaliam as transformações da paisagem urbana de lá para cá. / In the early 20th century, Ponta Grossa began to grow and stand out as one of the most important cities in the inland of Paraná. Development required a lot of water to supply the demand of both the rising population and the new ventures. Although the city was served by several streams, its capacity to provide water was low. Wells and fountains were not enough, being mandatory the search for rivers of greater volume of water for the construction of a system of supply and sewage. Throughout the process, from the search to the distribution, the city's first newspaper, "O Progresso", was in charge of informing the population about legal procedures, city hall decisions, residents' complaints, among other news in the region. To regulate the population, it was necessary a Code of Postures, which sought to impose certain norms necessary for the urban conviviality and above all, in times of expansion, to avoid the proliferation of diseases. However, the streams suffered the impacts of modernization, became increasingly polluted and seen as carriers of disease. Their courses then began to be channeled in order to mitigate the problem and take the sewage away from the city. For this research, some residents who lived near the streams until the 1950s gave interviews by telling how the environment was during their childhood and youth, their memories about these watercourses and how they evaluate the transformations of the urban landscape from here to here.

Mandioca, a rainha do Brasil? - Ascensão e queda da Manihot esculenta em São Paulo / Cassava, the queen of Brazil?: ascension and fall of the Manihor esculenta in São Paulo

Henrique Ataide da Silva 08 August 2008 (has links)
O cultivo da mandioca possui uma estreita relação com o campesinato brasileiro, estando presente entre seus cultivos desde sua gênese e ainda hoje é parte obrigatória da alimentação de vários segmentos da população brasileira das áreas rurais. Atualmente a maior parte da produção do tubérculo provém de áreas econômica e ecologicamente marginais sendo cultivado por meio de práticas agrícolas tradicionais, denominadas de agricultura de corte-e-queima. Porém, nos últimos anos a produção de mandioca tem apresentado uma contínua queda, principalmente no Estado de São Paulo, onde as transformações agrícolas foram mais intensas. Assim, é mediante a importância histórica do cultivo da mandioca entre os camponeses e a atual situação deste cultivo que colocamos nosso problema da seguinte forma: O declínio do cultivo da mandioca apresentado hoje não é um fenômeno recente, mas sim histórico se iniciando em outras épocas. Assim nosso objetivo principal é localizar as bases históricas do declínio do cultivo deste tubérculo entre os camponeses do Estado de São Paulo. Para atingir nosso objetivo adotamos o referencial teórico-metodológico da Historia Ambiental, que nos fornece elementos para fazer esta análise na perspectiva das relações entre as sociedades humanas e o mundo natural, usando para isso dados de diversas áreas como a Economia, a Antropologia, a Arqueologia, a Ecologia, além da História Social e Econômica. / The culture of the cassava has a narrow relationship with the Brazilian small rural culture, being present among its cultures since its genesis and until today it is a mandatory part of the feeding in some segments of the Brazilian population in the agricultural areas. Currently most of the tubercle production comes from economic and ecologically outskirt areas being cultivated through traditional agriculturists methods, called slash and burn agriculture. However, during the last years the cassava production has presented a continuous fall, mainly in the São Paulo state, where the agricultural transformations had been more intense. Thus, due the historical importance of the cassava culture between the peasants and the current situation of this culture, we place our problem on the following form: The current decline of the cassava culture is not a recent phenomenon, but historical and initiating at other times. Thus our main objective is to locate the historical bases of the decline of this tubercle culture among the peasants of the Sao Paulo state. To reach our objective we adopt the theoretician-methodological referential of the Environmental History, that supplies us elements to make this analysis in the perspective of the relations between the human societies and the natural world, using for this data from several areas as the Economy, the Anthropology, Archaeology, the Ecology, and also Social and Economic History.

Diagnosing A Silent Epidemic: The Historical Ecology of Metal Pollution in the Sonoran Desert

January 2019 (has links)
abstract: This research investigates the biophysical and institutional mechanisms affecting the distribution of metals in the Sonoran Desert of Arizona. To date, a long-term, interdisciplinary perspective on metal pollution in the region has been lacking. To address this gap, I integrated approaches from environmental chemistry, historical geography, and institutional economics to study the history of metal pollution in the desert. First, by analyzing the chemistry embodied in the sequentially-grown spines of long-lived cacti, I created a record of metal pollution that details biogeochemical trends in the desert since the 1980s. These data suggest that metal pollution is not simply a legacy of early industrialization. Instead, I found evidence of recent metal pollution in both the heart of the city and a remote, rural location. To understand how changing land uses may have contributed to this, I next explored the historical geography of industrialization in the desert. After identifying cities and mining districts as hot spots for airborne metals, I used a mixture of historical reports, maps, and memoirs to reconstruct the industrial history of these polluted landscapes. In the process, I identified three key transitions in the energy-metal nexus that drove the redistribution of metals from mineral deposits to urban communities. These transitions coincided with the Columbian exchange, the arrival of the railroads, and the economic restructuring that accompanied World War II. Finally, to determine how legal and political forces may be influencing the fate of metals, I studied the evolution of the rights and duties affecting metals in their various forms. This allowed me to track changes in the institutions regulating metals from the mining laws of the 19th century through their treatment as occupational and public health hazards in the 20th century. In the process, I show how Arizona’s environmental and resource institutions were often transformed by extra-territorial concerns. Ultimately, this created an institutional system that compartmentalizes metals and fails to appreciate their capacity to mobilize across legal and biophysical boundaries to accumulate in the environment. Long-term, interdisciplinary perspectives such as this are critical for untangling the complex web of elements and social relations transforming the modern world. / Dissertation/Thesis / Doctoral Dissertation Sustainability 2019

Cultivating leisure : agriculture, tourism, and industrial modernity in the North Carolina sandhills, 1870-1930

Winslow, Michael G. 01 December 2016 (has links)
This project is an environmental and cultural history of the sandhills region of North Carolina as it was transformed after the Civil War. It brings together agricultural science and the creation of a leisure industry in the sandhills to argue that they were interdependent in the transformation of the region. Chapter One narrates the gradual emergence and transformation of agricultural science in North Carolina from a venture of learned planters to a state-run institution, located in universities and government buildings, but still heavily influenced by the heirs of planters. Chapter Two examines the trajectory of resort creation in the sandhills after the region had been tapped out and cutover by naval stores producers and loggers. Its remained an agricultural problem area, while its acres of sandy land were available to be remade by developers. Importantly these new investors, like Pinehurst’s James and Leonard Tufts, reconstructed the sandhills to reflect a fantasy of yeoman agriculture—while deploying scientific findings and commercial fertilizers as advocated by state agricultural experts. Chapter Three analyzes a community that developed in the vicinity of Pinehurst after 1910, when a generation of idealistic Northern progressives turned to the sandhills, both to uplift the region and to escape the nervous problems they had experienced in the industrial North. Just as Pinehurst used agricultural science to create a leisure landscape, this group of Ivy Leaguers was inspired by visions of using agricultural technologies to turn the “sand barrens” into a state-of-the-art farmscape. Chapter Four turns to a literary account of the sandhills in the work of Charles Chesnutt, taking Chesnutt’s motif of gift-giving as a lens for understanding the author’s short stories set in the sandhills. This chapter focuses especially on Chesnutt’s conception of usufruct and an economy based in local social connections as an alternative to the version of commodity agriculture that had animated so many other projects in the sandhills. This dissertation reveals how the conceptual and material tools of an industrializing culture reconfigured this region, long seen as barren, from a cutover turpentine district into a tourist paradise.

An Environmental History of the Bear River Range, 1860-1910

Hansen, Bradley Paul 01 May 2013 (has links)
The study of environmental history suggests that nature and culture change all the time, but that the rate and scale of such change can vary enormously. During the late 19th and early 20th centuries, Anglo settlement in the American West transformed landscapes and ecologies, creating new and complex environmental problems. This transformation was particularly impressive in Cache Valley, Utah's Bear River Range. From 1860 to 1910, Mormon settlers overused or misused the Bear River Range's lumber, grazing forage, wild game, and water resources and introduced invasive plant and animal species throughout the area. By the turn of the 20th century, broad overuse of natural resources caused rivers originating in the Bear River Range to decline. To address the water shortage, a small group of conservation-minded intellectuals and businessmen in Cache Valley persuaded local stockmen and farmers to support the creation of the Logan Forest Reserve in 1903. From 1903 to1910, forest managers and forest users attempted to restore the utility of the landscape (i.e., bring back forage and improve watershed conditions) however, they quickly discovered that the landscape had changed too much; nature would not cooperate with their human-imposed restoration timelines and desires for greater profit margins. Keeping in mind the impressive rate and scale of environmental decline, this thesis tells the heretofore untold environmental history of the Bear River Range from 1860 to 1910. It engages this history from an ecological and social perspective by (1) exploring how Mormon settlers altered the landscape ecology of the Bear River Range and (2) discussing the reasons why forest managers and forest users failed to quickly restore profitability to the mountain landscape from 1903-1910. As its value, a study of the Bear River Range offers an intimate case study of environmental decline and attempted restoration in the western United States, and is a reminder of how sensitive our mountain ranges really are.

Jordens kretslopp : lantbruket, staden och den kemiska vetenskapen 1840-1910

Mårald, Erland January 2000 (has links)
This study of the institutionalization and professionalization of agricultural chemistry during the second half of the nineteenth century analyses the relationship between chemical theories and social issues, ideas and experience of recycling, the development of fertilizers, and industrialization of agriculture. The study mainly takes a history of science and environmental history perspective with focus on the Swedish case. It does, however, address the international context offering a historical perspective of issues such as the relationship between population and natural resources, the sustainability of society and connections between science, technology and nature. The center of this study consists of an analysis of the work of the following agricultural chemists employed by the Swedish Royal Agricultural Society, enumerated in chronological order: Alexander Müller, Carl Erik Bergstrand, and Lars Fredrik Nilson. Other actors, such as agriculturists, administrators and politicians, were also important in the formation of agricultural chemistry in Sweden. Changes of aims and agricultural chemical ideals during the period of study reflect changes in society and shifting ideologies. During the second half of the nineteenth century a national "agricultural scientific infrastructure" was erected with experimental stations, agricultural schools, local experimental fields and agrarian experts. This network constituted a basis for agricultural science in society and functioned as an important channel for the modernization of agriculture and society. With agricultural chemistry as an empirical point of departure, this thesis also analyzes the transformations of agriculture with the establishment of cultural, economical and physical links between agriculture and the surrounding world. Theories about chemical cycles promoted recycling of nutrition and other materials between the city and the countryside, thereby connecting agriculture to the city. The development of new mineral and nitrogenous fertilizers gradually involved an increased use of inorganic raw materials and energy to manufacture nutrition. This process resulted in the intertwining of agriculture, science, mining, industry and energy production and the creation of an agro- industrial network, which was crucial for the development of agriculture during the twentieth century. In this context, agricultural science legitimized the development toward resource intensive farming methods. / digitalisering@umu

Framing Transfrontier Nature Conservation : The Great Limpopo Transfrontier Park and the Vision of 'Peace Parks' in Southern Africa

Berglund, Kristina January 2015 (has links)
Within the broad field of global environmental history this master thesis analyses transfrontier conservation areas (TFCAs) also known as 'peace parks', and explores how the Great Limpopo Transfrontier Park (GLTP) has been envisioned, described, motivated and implemented. Using Actor-Network Theory and Framing Analysis, the thesis analyses how the idea of the GLTP and the critique against it has been framed over time through the analysis of official reports and academic research in combination with in-depth interviews with key actors. By approaching the topic of transfrontier conservation in a broad manner, and by incorporating a wide variety of sources, the thesis attempts to go beyond single explanations of the phenomenon and, instead, provide a more comprehensive and nuanced understanding of the transfrontier conservation idea linked to the GLTP and its history. The thesis shows that the rise of transfrontier conservation involves a complex network of actors, spanning over local-global and public-private scales. Integrated networks are formed between key actors including national governments and conservation authorities, donor agencies, NGOs – in particular the Peace Parks Foundation, and civil society. The GLTP has been framed as a way to achieve three main goals: biodiversity conservation, community development through ecotourism and public-private partnerships, and regional peace and security. The thesis shows that the framing has shifted over time, from a strict conservation focus to more inclusive approaches where social aspects are seen as increasingly important for the long term sustainability of TFCAs. But the idea that transfrontier conservation can resolve all regional problems, from political cooperation to wildlife management to local socio-economic development, is also contested in this study. The thesis illuminates a gap between official policy/management reports and academic studies related primarily to the role of community development in the framing and implementation of the GLTP. Despite various challenges that hinder the effective implementation of the goals and visions of the park such as wildlife crime, insufficient community involvement and problematic legal and policy arrangements, the thesis concludes that the GLTP represents an important contribution to global conservation commitments and needs to be viewed as a complex, long-term and constantly evolving project.

The Wolf Dilemma : Following the Practices of Several Actors in Swedish Large Carnivore Management

Ramsey, Morag January 2015 (has links)
The wolf is an endangered animal in Sweden and the issue of conserving the species is a polarizing one. Specific attention has been given to this issue in environmental social sciences with studies focusing on the divide between wolf support and opposition. These studies include looking at historical interactions with the wolf, contemporary attitudes about the issue, and the way the law shapes policy. Following this focus on the disputed nature of wolf conservation, this thesis addresses whether polarization over the issue occurs between several stakeholders in large carnivore management in Sweden. Using Actor Network Theory, this thesis examines the similarities and divergences in the stakeholders’ conservation practices and maps their interactions with one another. Emphasis is placed on how the European Union’s regulations and the Swedish State’s policies conflict and/or influence the stakeholders. Overall results show that despite a discourse of polarization surrounding wolf management in Sweden, the actors in this study cannot be easily positioned against each other, and despite some divergences, share many similarities in their large carnivore management practices.

Locality and empire : networks of forestry in Australia, India, and South Africa, 1843-1948 / Networks of forestry in Australia, India, and South Africa, 1843-1948

Bennett, Brett Michael 13 November 2012 (has links)
This dissertation draws from national and regional archives to argue that many important aspects of forestry science, education, and culture in colonial Australia, India, and South Africa developed according to unique local environmental, political, social, and cultural influences. Local environmental constraints, combined with unique cultures of experimentation, encouraged the innovation of new scientific methods for forming timber plantations that differed from existing European and British methods. Debates over how to create forestry schools to train foresters in each region emphasized local problems and contexts rather than focusing primarily on continental European precedents or methods. The culture of foresters in each region corresponded to local cultures and social conditions as much as to a larger imperial ethos inculcated by training in continental European or British forestry schools. / text

Masters not friends : land, labor and politics of place in rural Pakistan

Rizvi, Mubbashir Abbas 07 November 2013 (has links)
This dissertation analyzes the cultural significance of land relations and caste/religious identity to understand political subjectivity in Punjab, Pakistan. The ethnography details the vicissitudes of a peasant land rights movement, Anjuman-e Mazarin Punjab (Punjab Tenants Association) that is struggling to retain land rights on vast agricultural farms controlled by the Pakistan army. The dissertation argues that land struggles should not only be understood in tropes of locality, but also as interconnected processes that attend to global and local changes in governance. To emphasize these connections, the dissertation gives a relational understanding of 'politics of place' that attends to a range of practices from the history of colonial infrastructure projects (the building of canals, roads and model villages) that transformed this agricultural frontier into the heart of British colonial administration. Similarly, the ethnographic chapters relate the history of 'place making' to the present day uncertainty for small tenant sharecroppers who defied the Pakistan Army's attempts to change land relations in the military farms. Within these parameters, this ethnographic study offers a "thick description" of Punjab Tenants Association to analyze the internal shifts in loyalties and alignments during the course of the protest movement by looking at how caste, religious and/or class relations gain or lose significance in the process. My research seeks to counter the predominant understanding of Muslim political subjectivity, which privileges religious beliefs over social practices and regional identity. Another aspect of my work elucidates the symbolic exchange between the infrastructural project of irrigation, railway construction and regional modernity in central Punjab. The network of canals, roads and railways transformed the semi-arid region of Indus Plains and created a unique relationship between the state and rural society in central Punjab. However, this close relationship between rural Punjab and state administration is not void of conflict but rather it indicates a complex sense of attachment and alienation, inclusion and exclusion from the state. / text
