Geographers researching cinema have predominantly been interested in how geographic meaning is constructed and negotiated within film, but have been less productive in accounting for how these constructs are received by viewers. Using the method of observational online ethnography, I therefore investigate how fans in online reviews have interpreted the nature/society binary in the film Dersu Uzala. Working from a social constructionist view of nature I begin by deconstructing the binary as it appears in Dersu Uzala before proceeding to illustrate the way this constitutive absence is made up for by the visuality of the film’s landscapes and techniques of geographic realism. Turning to the fan reviews I find that, rather than challenge the historical and constructed division between nature and society, many fans accept the binary as inevitable and consistent with their ideas about contemporary reality. More than passive consumption however, this concurrence is actively rearticulated in the ways that the fans incorporate the binary into their own lives and in the new discursive practices of the internet. In so doing I make headway into the exploration of audience analysis by geographers and continue to advance geography’s foray into cultures of the internet.

Awareness of extreme high tide flooding in coastal communities has been increasing in recent years, reflecting growing concern over accelerated sea level rise. As a low-lying, urban coastal community with high value real estate, Miami often tops the rankings of cities worldwide in terms of vulnerability to sea level rise. Understanding perceptions of these changes and how communities are dealing with the impacts reveals much about vulnerability to climate change and the challenges of adaptation. This empirical study uses an innovative mixed-methods approach that combines ethnographic observations of high tide flooding, qualitative interviews and analysis of tidal data to reveal coping strategies used by residents and businesses as well as perceptions of sea level rise and climate change, and to assess the relationship between measurable sea levels and perceptions of flooding. I conduct a case study of Miami Beach’s storm water master planning process which included sea level rise projections, one of the first in the nation to do so, that reveals the different and sometimes competing logics of planners, public officials, activists, residents and business interests with regards to climate change adaptation. By taking a deeply contextual account of hazards and adaptation efforts in a local area I demonstrate how this approach can be effective at shedding light on some of the challenges posed by anthropogenic climate change and accelerated rates of sea level rise. The findings highlight challenges for infrastructure planning in low-lying, urban coastal areas, and for individual risk assessment in the context of rapidly evolving discourse about the threat of sea level rise. Recognition of the trade-offs and limits of incremental adaptation strategies point to transformative approaches, at the same time highlighting equity concerns in adaptation governance and planning. This new impact assessment method contributes to the integration of social and physical science approaches to climate change, resulting in improved understanding of socio-ecological vulnerability to environmental change.

Given the state of the planet at present —specifically, the linked global ecological and economic crises that conjure dark imaginings and nihilistic actualities of increasing resource depletion, poisonings, and wide-scale sufferings and extinctions—I ask What might we hope now? What points of intervention offer possibility for transformation? At best, the response can only be partial. The approach this thesis takes initiates from specific pre-discursive assumptions. The first understands current conditions as having been produced, and continuing to be so, through practices that enact and sustain neoliberal relations. Secondly, these practices are expressive of a subjectivity tied to a Cartesian worldview, which, therefore, needs to be interrupted at its foundational roots. Thirdly, the scaffolding that supports this subjectivity draws on Newtonian science and neo-Darwinian narratives deemed to be natural law and, therefore, ontological, immutable reality. Contrary to modernist thinking, I premise that these two strains, subjectivity and science, are neither autonomous nor ontological, but that they are materially and contingently integral. Finally, this thesis presumes that different and life-affirming trajectories are, in fact, desired. An integral framing of science and subjectivity provides a productive method of feminist science studies analysis and theorization. Observing the capitalist Western social imaginary through this lens reveals its philosophical and scientific infrastructures to be outdated and crumbling. Observing how emerging scientific narratives in quantum physics and systems-biology intersect with marginalized theories in process-philosophy and subjectivity reveals a life-affirming imaginary of difference, one that arrests nihilism and sets ethical trajectories in motion. Certain, though not all, percepts of feminist new materialism engage twentieth and twenty-first century sciences successfully to show that ethicality matters. Though many questions remain, this points auspiciously towards the possibility for a transformed politics of justice.

In the Portland, Oregon, metropolitan area, suburban cities such as Hillsboro are projected to grow as people seek affordable housing near a rapidly growing metropolis. This thesis examines the combined impact of'c1imate change and urban development on both neighborhood and municipal scale residential water demand in Hillsboro, Oregon. I use two models, a surface energy balance model, Local-scale Urban Meteorological Parameterization Scheme (LUMPS), and a system dynamics model, CCDomestic, to investigate changes in residential water demand in the 2040s at two distinct spatial scales, the neighborhood and the municipality. I calibrate and validate each model to the reference period and then simulate the future (2030-2059) under three statistically downscaled global climate models and two urban development scenarios. The findings of this study indicate that climate change and urban development will not evenly affect water consumption in neighborhoods across a city. Instead, the current land cover and residential density of a neighborhood exert an important influence on the response. Heavily vegetated neighborhoods exhibit large increases in water demand under urban sprawl and warming scenarios, while neighborhoods dominated by impervious surfaces decrease water consumption under sprawl scenarios and show little change in water consumption under combined sprawl and warming scenarios. At the municipal scale findings suggest that water demand is highly sensitive to urban design and management and that the combination of urban densification and water conservation regulations could mitigate increases in water consumption from population growth and climate change.

This thesis explores the forces of change in lives and landscapes that have altered the Lamosangu-to-Everest route in northeastern Nepal and shows how a transect in photographs and conversations across the east-central Himalaya allows us insight and a greater understanding into the processes and consequences of this change. Three forces of change over the last twenty-five years dominated discussions with local informants: the rise of the "People's War"-Nepal's Maoist Insurgency beginning in 1996; the Democratic Revolution of 1990; and dependence on tourism for livelihood after the establishment of Sagarmatha National Park in 1976. Understanding the cultural-historical context for these forces is necessary to understand the concerns of today's residents living along the Lamosangu-to-Mount Everest Base Camp transect. The visual and ethnographic evidence discussed in this thesis takes a larger role than strict analysis of conspicuous large-scale land use change and I hope the comparative 200 I images will be used as benchmarks for future research as well as for further exploration into the ways people and place have been represented.

During the past fifteen years, non-timber or special forest products have become an important economic resource in the Pacific Northwest. These products are primarily derived from understory species and contribute approximately $200 million to the regional economy. Medicinal plants are a little researched component of the non-timber forest product industry that relies on cultivated and wildcrafted (or wild-collected) medicinal plant species. This study examines the commercial extraction of wildcrafted medicinal plants from Mount Hood National Forest. Specifically, this study documents the medicinal plant species extracted from Mount Hood National Forest, their annual yield amounts, harvesting methods, and the changes in cover of target species after harvest. This research uses survey data obtained from employees of two herbal companies and representatives of the U.S. Forest Service to describe medicinal plant extraction and administration as it pertains to the commercial extraction of plant species from Mount Hood National Forest. Field data were also used to examine changes in plant cover for four medicinal plant species (kinnikinnick, yarrow, Oregon grape and valerian) following harvest. Field results indicate that medicinal plant cover decreased significantly in all but one harvested sampling unit. Permanent unit markers were established at all the study sites to provide opportunities for long-term monitoring of target species responses to harvest. Eleven medicinal plant species are commonly collected for commercial purposes from Mount Hood National Forest. The general lack of regulation and enforcement of commercial medicinal plant extraction coupled with an increasing demand for wildcrafted medicinal plants warrant a need for increased collaboration between regulatory agencies, herbal companies, and the general public. Additional management and research recommendations regarding the ecological impacts of medicinal plant removal are also presented.

In-stream aquatic habitat depends on adequate levels of dissolved oxygen. Human alteration of the landscape has an extensive influence on the biogeochemical processes that drive oxygen cycling in streams. Historic datasets allow researchers to track trends in chemical parameters concomitant with urbanization, while land cover change analysis allows researchers to identify linkages between water quality trends and landscape change. Using the Seasonal Kendall's test, I examined water quality trends in oxygen demand variables during the mid-1990s to 2003, for twelve sites in the Rock Creek sub-watershed of the Tualatin River, northwest Oregon. Significant trends occurred in each parameter. Dissolved oxygen (DO (%sat)) increased at five sites. Chemical oxygen demand (COD) decreased at seven sites. Total Kjeldahl nitrogen (TKN) decreased at five sites and increased at one site. Ammonium (NH3-N) decreased at one site and increased at one site. Multiple linear regression indicates that nitrogenous oxygen demand accounts for a significant amount of variance in COD at ten of the twelve sites (adjusted R2values from 0.14 to 0.73). Aerial photo interpretation revealed significant land cover change in agricultural land cover (-8% for the entire basin area) and residential land cover (+10% for the entire basin area). Correlation results between seasonal oxygen demand data and land cover values at multiple scales indicated that: (I) forest cover negatively influences COD at the full sub-basin scale and positively influences NH3-N at local scales, (2) residential land cover positively influences DO (%sat) values at local scales, (3) agricultural land cover does not influence oxygen demand at any land cover assessment scale, ( 4) local topography negatively influences TKN and NH3-N, and (5) urban runoff management infrastructure correlates positively with COD. Study results indicate that, with the exception of forested land, local scale land cover and landscape variables dominate influence on oxygen demand in the Rock Creek basin. Since DO conditions have improved in these streams, watershed management efforts should emphasize local influences in order to continue to maintain stream health.

This thesis is a history of the navigation on the San Joaquin River from 1848 until 1925. The main purpose of the thesis will be to examine chronologically any and all events and factors concerned with the navigation of the river during that period of time. The first chapter will survey the geographical and historical background of the San Joaquin River. The emphasis will be placed on the river's use for navigation. Since the upper, southern third of the San Joaquin Valley does not drain into the San Joaquin River, only those areas between the Kings River on the south and the Cosumnes River on the north will be included in this study.

This thesis examines the changing perceptions of Vietnam’s landscape and the Vietnamese in the eyes of American troops throughout the Vietnam War. Throughout the late 1950s and early 1960s, the Vietnamese were depicted as a people misguided by the French and in need of political mobilization by the American media and government. Following heavy investment and a rigged election in 1956, South Vietnam was painted as a beacon of democracy in Southeast Asia and an example of what American aid is capable of. As an increasing American military presence was being established in South Vietnam in the early 1960s, American troops were reminded by pocket books and other forms of American propaganda that South Vietnam was a land of dignity and respect. At first, troops were shocked by the beauty of the landscape and recalled that Vietnam did not look like a war-torn country at all. Yet as the land became increasingly devastated due to defoliant and numerous bombings, the perceptions of the Vietnamese took a turn for the worst; eventually being subhuman and deceptive. Vietnam’s landscape became perceived as a land of death where youth was expendable. However, less than a decade after the United States had pulled out of Vietnam, veterans and those affected by the war begin to return in mass numbers constituting the largest population of Americans in Vietnam. This resulted in Vietnam’s landscape, which was seen as a land trap-laden wasteland, being seen a place of healing with a beautiful people that Americans helped save.

Encouraging a more sustainable commuter mode shift and improving urban transportation systems have the potential to reduce anthropogenic greenhouse gas emissions (GHGs), a major contributor to climate change. Replacing some single-occupancy vehicle (SOV) trips with alternative modes of transportation, such as public transit, walking, or bicycling, represents one approach to begin reducing transportation-related emissions. Collectively, these shifts in transportation patterns would help to reduce the negative social, economic, and environmental costs associated with high rates of personal vehicle use. Employer-provided benefits programs have the potential to influence commuter behavior by making sustainable, alternative commuting choices a more convenient and economically feasible option. In addition, the implementation of these programs can have broader benefits such as helping to achieve municipal and regional sustainability goals and improving community members’ physical health and quality of life. This study applies qualitative and quantitative analysis to investigate employee commuting behavior in response to employer-provided benefits in Kendall Square, a neighborhood in Cambridge, Massachusetts. The employee and employer survey data analyzed in this research was originally collected by TransAction, a transportation consulting firm in the Greater Boston region. To comply with Cambridge’s Parking and Transportation Demand Management (PTDM) Ordinance, TransAction works closely with companies to coordinate and manage onsite commuter services programs and prepare PTDM Annual Reports. The primary objectives of this research are: 1) to introduce the multi-dimensional benefits of re-envisioning the existing transportation networks; 2) to determine the influence of employer-provided commuting benefits on employee commute mode choice; 2) to provide guidance for employers interested in promoting a more sustainable employee commute mode split; and 3) to present the broader implications and applications of this research for employers, municipalities, and coordinating agencies interested in reducing SOV commuting trips and promoting the use of more sustainable, alternative modes of transportation. Overall, the findings from this research illustrate that while employers have the ability to promote more sustainable transportation choices among their employees, the complexity of the transportation network (and its interdependencies) requires collaboration among all stakeholders to initiate widespread, comprehensive changes.
