Les historiens de l’environnement s’attachent à déchiffrer les modes de relation entre l’homme et la nature aux Etats-Unis. La manière dont elle est définie conditionne les politiques environnementales, et donc contribue à la transformation matérielle du continent. Cinq traditions de la pensée environnementale américaine sont décrites : la nature comme ressource transformée par le travail ; le préservationnisme ; le conservationnisme ; l’écologie ; et la justice environnementale. Ces idées perdurent au XXIème siècle dans les discours construits au sujet de la nature : elles se juxtaposent ou se confrontent. L’objectif de ce travail est de savoir si elles se transforment, en évoluant vers une définition de la relation homme/nature comme hybride socionaturel. À cette fin, trois cas sont étudiés, tous situés dans la région de Los Angeles au début des années 2000. Le premier concerne le ranch Tejon, dont l’accord passé en 2008 entre associations de protection de la nature et propriétaires pose la question du sens donné à une préservation qui veut prendre en compte les aspects à la fois écologiques, mythiques et économiques de ce territoire, vestige du passé de l’Ouest. Le second se rapporte à la décision prise en 2007 par la ville de Los Angeles de revitaliser son fleuve et fournit un exemple de l’élargissement de la définition de la nature : celle-ci peut être urbaine. Enfin, troisième cas, la justice environnementale appliquée à la ferme communautaire de South Central Los Angeles, entretenue de 1994 à 2006, est signe de la transition de la pensée de la nature américaine d’un objet délimité dans l’espace vers une problématique mondiale. / Environmental historians have worked at redefining the modes of relationship between man and nature in the United States. The way this relation is defined conditions environmental politics, and therefore contributes to the material transformation of the continent. Five major trends of thought about nature are described: nature as a resource transformed by work ; preservationism ; conservationism ; ecology ; and environmental justice. Those ideas endure to this very day in the discourses constructed about nature: they either juxtapose or confront each other. The goal of this thesis is to understand whether they undergo a transformation, evolving towards a definition of the man/nature relationship as a socionatural hybrid. To this end, three cases are examined here, all of which are connected with the Los Angeles area in the early 2000s. The first concerns Tejon Ranch and the agreement passed in 2008 about Tejon Ranch between environmental associations and the owners : it poses the question of the meaning given to a preservation that would incorporate ecological, mythical and economic aspects of that territory, a remain of the Western past. The second deals with the decision that was made in 2007 by the City of Los Angeles to revitalize its river and offers a good example of the broadening of the definition of nature: it can also be urban. The ecological and cultural preoccupations about the river complicate the conservation problematic in Southern California. Finally, South Central Farm’s environmental justice case (1994-2006) is the sign of a transition in American environmental ideas from a clearly spatially limited object to a world issue.

This thesis deals with waste and waste management in 19th century in Prague. The theoretical basis is the concept of "urban metabolism", which part is waste, as the metabolic output. Waste is also seen as an example of interactions between city and its hinterland. The intention of this thesis is to prove the proposition on the case of Prague, that the 19th century wasn't the century of waste. At the time of progressing industrialization and demand of raw materials there was the tendency to reuse every potentially usable material. This thesis describes based on literature and especially on analysis of archival documents the particular steps of waste management in 19th century in Prague (city cleaning, collection, transport and disposal of waste), whereas the main concern lays in interaction of city and its hinterland in context of waste disposal. The results of the analysis are widely interpreted in conclusions. key words: waste, waste management, Prague, "the long" 19th century, process of industrialization, interactions of city and its hinterland, social and urban metabolism, environmental history

Mammoth Cave in Kentucky is the longest known cave in the world. This dissertation examines the history of how scientists and non-scientists alike contributed to a growing body of knowledge about Mammoth Cave and how that knowledge in turn affected land use decisions in the surrounding neighborhood. During the nineteenth century visitors traveled through Mammoth Cave along with their guides, gaining knowledge of the cave by using their senses and spreading that knowledge through travel narratives. After the Civil War, cave guides, now free men who chose to stay in the neighborhood, used the cave as a way to build and support their community. New technologies and new visitors reconstructed the Mammoth Cave experience. Competing knowledge of locals and science-minded individuals, new technologies to spread the cave experience, and a growing tourism industry in America spurred the Kentucky Cave Wars during the late-nineteenth century. In the twentieth century, cutthroat competition between caves crystallized support for a national park at Mammoth Cave. Park promoters met resistance. Cave owners’ knowledge of what they owned underground helped them resist condemnation. Those affected by the coming of the national park made their protests known on the landscape, in newspapers, and in courtrooms. The introduction of New Deal workers, primarily the Civilian Conservation Corps, at Mammoth Cave and a skeleton staff of National Park Service officials faced antagonism from the local community. Important discoveries inside Mammoth Cave hastened the park’s creation, but not without lingering bitterness that would affect later preservation efforts. The inability of the park promoters to acquire two caves around Mammoth Cave was a failure for the national park campaign but a boon for exploration. The postwar period saw returning veterans and their families swarming national parks. While the parking lots at Mammoth Cave grew crowded and the Park Service attempted to balance preservation and development for the enjoyment of the visiting public, underground explorers were pushing the cave’s known extent to new lengths. This new knowledge inspired a new generation of environmentalists and preservationists to use the Wilderness Act to advocate for a cave wilderness designation at Mammoth Cave National Park.

<p>This project argues that industrial fires have the capacity to illuminate the complex entanglements (political, ecological, economic, etc.) of life in the era of industrial capitalism. It retells and reframes the stories of five such fires, each off which shines a light on the networks of social, political, technological, economic, and ecological relationships in particular communities at particular moments. It thus contributes to the interdisciplinary fields of American Studies and the environmental humanities, furthering our understanding of the unfolding experience of industrial capitalism in the twentieth and twenty-first century United States. It takes the form of a public humanities project and is produced for a popular audience, using journalistic, literary, historical, and other techniques to tell the stories of these fires. In doing so, I also hope to contribute to the expansion of public humanities scholarship and help foster a thriving and creative future for the humanities both in academia and beyond.</p>

[pt] O processo de ocupação humana no território brasileiro tem provocado, há séculos, profundas alterações no meio ambiente. Desde os primeiros habitantes, a natureza tem sofrido alguma mudança no seu formato, em algum grau de escala. Se os povos tradicionais nativos possuem uma preocupação em conciliar a relação homem-meio ambiente, a invasão europeia inverteu toda essa lógica. Dos processos primitivos até o uso da mecanização moderna, o Brasil pós-1500 mostrou a força humana sobre a natureza e seus consequentes impactos. Apesar dos esforços maiores ou menores, das denúncias propaladas desde do período colonial, avança-se a destruição de ecossistemas de suma importância local e global. Diante desse cenário, o país possui biomas com enorme perigo de perdas irreversíveis se nada for feito. Neste contexto, esta tese tem como objetivo entender essas transformações com olhares histórico, geográfico e econômico, culminando numa análise quantitativa do uso da terra de 2004 a 2019 focada nos municípios dos dois principais biomas brasileiros ameaçados, Cerrado e Amazônia. Por meio de diferentes instrumentos da econometria espacial cujos princípios são as primeiras leis da Geografia, se pretende identificar os fatores que modificaram o uso da terra no período citado e propor medidas para atenuar o impacto do principal vetor de desmatamento direto nos biomas citados: a pecuária. Por meio dessa análise, pretende-se avaliar como a intensificação da bovinocultura de corte altera as emissões, a configuração do uso da terra, pode auxiliar no cumprimento da Lei de Proteção da Vegetação Nativa e gerar ganhos econômicos dentro de uma área com mais de 1.700 municípios. O objetivo final é determinar qual a melhor política de intensificação da atividade de pecuária de corte considerando o trade-off meio ambiente e economia. A escolha permitirá que o país consiga oferecer aos consumidores domésticos e internacionais uma atividade mais sustentável com minimização do impacto ambiental gerado e receitas majoradas. Com isso, a tese mostra que as alterações no uso da terra em quatro diferentes classes – agricultura, pecuária, floresta e outros usos – são fenômenos locais cujo somatório tem um impacto global relevante. Os resultados reforçam a importância de políticas públicas ambientais e agrícolas e observarem as diferenças entre os municípios em sua formulação e implementação. Há, para o Brasil, um imenso potencial tanto de ampliar a área florestal com a intensificação e de restaurar grandes áreas liberadas com o incremento do sistema produtivo de carne bovina. Assim, o país tem nas suas mãos uma chance ímpar de ter uma pecuária sustentável econômica e ambientalmente com uma política governamental que considere a diversidade local. / [en] The process of human occupation in Brazilian territory has caused profound changes in the environment for centuries. Since the first inhabitants, nature has undergone some change in its shape, to some degree of scale. If native traditional peoples have a concern to reconcile the man-environment relationship, the European invasion has reversed all this logic. From primitive processes to the use of modern mechanization, post-1500 Brazil showed human strength under nature and its consequent impacts. Despite the major or minor efforts, the denunciations proposed since the colonial period, the destruction of ecosystems of great local and global importance is advanced. Given this scenario, the country has biomes with enormous danger of irreversible losses if nothing is done. In this context, this thesis aims to understand these transformations in historical, geographical, and economic views, culminating in a quantitative analysis of land use from 2004 to 2019 focused on the municipalities of the two main threatened Brazilian biomes, Cerrado and Amazon. Through different instruments of spatial econometrics whose principles are the first laws of geography, it is intended to identify the factors that modified land use in the period mentioned and propose measures to mitigate the impact of the main vector of direct deforestation in the biomes mentioned: livestock. Through this analysis, it is intended to evaluate how the intensification of beef cattle culture alters emissions, the configuration of land use, can assist in complying with the Native Vegetation Protection Law and generates economic gains within an area with more than 1,700 municipalities. The goal is to determine the best policy of intensification of beef livestock activity considering the trade-off environment and economy. The choice will allow the country to be able to offer domestic and international consumers a more sustainable activity with minimization of the environmental impact generated and increased revenues. Considering all these facts, the thesis shows that changes in land use in four different classes – agriculture, livestock, forest, and other uses – are local phenomena whose sum has a relevant global impact. The results reinforce the importance of environmental and agricultural public policies and the observer in the differences between the municipalities in their formulation and implementation. For Brazil, there is an immense potential for both expanding the forest area with intensification and restoring large areas released with the increase of the beef production system. The country has in its hands a unique chance to have a sustainable livestock economically and environmentally with a government policy that considers local diversity. / [fr] Le processus d occupation humaine sur le territoire brésilien a provoqué de profonds changements dans l environnement pendant des siècles. Depuis les premiers habitants, la nature a subi quelques changements dans sa forme, à un certain degré d échelle. Si les peuples autochtones traditionnels ont le souci de concilier la relation hommeenvironnement, l invasion européenne a inversé toute cette logique. Des processus primitifs à l utilisation de la mécanisation moderne, le Brésil post-1500 a montré la force humaine sous la nature et ses impacts conséquents. Malgré les efforts majeurs ou mineurs, les dénonciations proposées depuis la période coloniale, la destruction d écosystèmes d une grande importance locale et mondiale progresse. Compte tenu de ce scénario, le pays a des biomes avec un énorme danger de pertes irréversibles si rien n est fait. Dans ce contexte, cette thèse vise à comprendre ces transformations avec des vues historiques, géographiques et économiques aboutissant à une analyse quantitative de l utilisation des terres de 2004 à 2019 des municipalités des deux principaux biomes brésiliens menacés, le Cerrado et l Amazonie. A travers de différents instruments d économétrie spatiale dont les principes sont les premières lois de la géographie, il est prévu d identifier les facteurs qui ont modifié l utilisation des terres dans la période mentionnée et de proposer des mesures pour atténuer l impact du principal vecteur de déforestation directe dans les biomes mentionnés : l élevage. Grâce à cette analyse, il est prévu d évaluer comment l intensification de la culture des bovins modifie les émissions, la configuration de l utilisation des terres, peut aider à se conformer à la Loi sur la protection de la végétation native et générer des gains économiques dans une zone comptant plus de 1.700 municipalités. L objectif est de déterminer la meilleure politique d intensification de l activité du bétail en tenant compte de l environnement et de l économie compromis. Ce choix permettra au pays d être en mesure d offrir aux consommateurs domestiques et internationaux une activité plus durable avec une minimisation de l impact environnemental généré et une augmentation des revenus. Avec cela, la thèse montre que les changements dans l utilisation des terres dans quatre classes différentes – l agriculture, l élevage, la forêt et d autres utilisations – sont des phénomènes locaux dont la somme a un impact mondial pertinent. Les résultats renforcent l importance des politiques publiques environnementales et agricoles et regardent les différences entre les municipalités. Pour le Brésil, il existe un immense potentiel à la fois pour l expansion de la zone forestière avec l intensification et la restauration de grandes zones libérées avec l augmentation du système de production de bœuf. Le pays a entre ses mains une chance unique d avoir un élevage durable économique et écologiquement avec une politique gouvernementale qui prend en compte la diversité locale.

While the role of photography in enforcing hegemonic ideologies has been amply studied, this thesis addresses the under-researched topic of how photography undermined dominant narratives in specific historical circumstances. I argue that, in the later part of the long nineteenth century, photographs were used to represent the natural world in contexts where their functions were uncertain and their capacities not clearly defined, and that these hesitations allowed for the expression of resistances to dominant social attitudes towards nature. I analyse how these divergences were articulated through three independent case studies, each addressing a corpus of photographs which has been marginalised in scholarly discourse. The case studies all concern photographs of vegetation. The first one discusses photographs produced around Fontainebleau during the Second French Empire, commonly understood as auxiliary materials for Barbizon painters, and argues that they were in fact autonomous representations, reflecting marginal modes of experiencing nature which resisted its prevailing construction as spectacle. The second case study examines a photographic series depicting Amazonian vegetation, published between 1900 and 1906, and shows how, in attempting to satisfy conflicting ideological demands, these photographs undermined the hierarchies enforced upon the natural world by colonial science. The third case study analyses photographs from an early twentieth-century environmentalist treatise, and demonstrates how, while the author's discourse seemingly complied with conventional attitudes towards nature, the photographs instituted an ethical stance opposed to early conservation's aesthetic focus and anthropocentrism. Throughout the case studies, I argue that the photographs were consubstantial to the emergence of these resistances; that dissenting representations stemmed from a tension between their producers' lived experience and the ideological frameworks which informed each context; and that this process engendered remarkable formal innovations, which are not usually associated to non-artistic images. I contend that radical renewals of visual expression occur in all representational contexts, as image producers adapt their tools or forge new ones according to circumstances, and that more attention must be paid to such visual innovations outside the field of artistic production.
