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.

In recent years, the Western United States has experienced an increase in fire activity due to multiple factors, including anthropogenic climate change, historical forest management focused on suppression, and the expanding wildland urban interface (WUI). In response, California is working to accelerate the pace and scale of forest management and fire hazard reduction efforts. Although fuel treatment projects are being implemented, they often encounter various barriers. While existing literature highlights these barriers, it tends to overlook the solutions being applied in practice to overcome them. Using an ethnographic approach that includes key informant interviews and participant observation in four sites within California’s Coast Ranges, we identify both the barriers and the solutions being used ‘on the ground.’ Our findings reveal that many of the previously identified barriers elsewhere also exist in the Central California Coast Ranges. Trust emerges as a critical factor for the successful implementation of fuel treatments, yet it is not just about recognizing its importance. Our research builds on existing literature by documenting specific strategies used to overcome these barriers, showing not only that relationships and trust are valuable, but also how they can be actively developed. By addressing the interconnected variables underlying fuel treatment barriers through the intentional development of personal and professional relationships, practitioners can more effectively implement fuel treatment projects in California.

Access to water from San Antonio Creek was critical in Claremont’s growth from a small stop on the Santa Fe Railroad to an agricultural powerhouse and an elite college town. While Claremont has sought to distinguish itself from surrounding communities since its founding in 1882, the innovative Pomona Valley Protective Association (PVPA) aligned Claremont with the City of Pomona and its other neighbors in a scheme to conserve the Creek’s resources at the turn of the century. Organized around the discovery of local confined aquifers and the development of a strategy to recharge them with water from the San Antonio Creek, the Association was a contradictory moment of cooperation in an otherwise highly contentious zero-sum game of water rights politics. As conflicts wore on, the PVPA quietly orchestrated the purchase of large tracts of land in the San Antonio Creekbed, where the construction of diversion dams and spreading grounds served dual purposes of water conservation and flood control. As dam building in the Creekbed continued, large tracts of the previously undevelopable Wash were transferred to the aggregate mining institutions that gouged the area’s many gravel pits. This thesis uses the story of the PVPA and the contemporary example of the Claremont University Consortium Gravel Pit to explore the context of development in the San Antonio Creek Wash. Understanding the political and social contexts of the gravel quarry problem reveals possibilities for a more integrative, conscious, and sustainable approach to improving the former gravel quarries that currently occupy the Wash landscape.

This dissertation examines how confusion and lack of access to information about subsurface property rights facilitates the rapid acquisition of mineral rights by mining interests, leaving those who live 'above the surface' to contend with complicated corporate and bureaucratic apparatuses. The research focuses on the first proposed state-run large scale mining project in Ecuador, believed to contain copper ores, and on the natural gas hydrofracking industry in three counties in north central West Virginia. Qualitative and visual methods, including mapping, are employed to determine (i.) how the geography of subsurface ownership patterns is changing, (ii.) links between changes in subsurface ownership and surface ownership, and (iii.) how these changes are facilitated or impeded by institutional and governance practices. Rights and permit acquisitions are facilitated by state institutions, which often have strategic interests in mineral development. Accordingly, this research also considers the role of state strategy with respect to the establishment, bureaucratic management, and enforcement of vertical territory, which reflects the state’s interest in and sovereign claim over subterranean resources to benefit the nation. The research finds that the historical separation of subsurface property rights from the surface is associated with a persistent weakening of surface holder claims to land in favor of mining development, and that this weakening has contributed to the long-term persistence of absentee ownership and control over land in Ecuador and West Virginia. Viewing subsurface land deals from the perspective of those whose lives are disrupted on the surface, I conclude from this work that mundane practices such as deed transfers and local micropolitics about land use are significant factors in the lead up to larger scale violences and silences, such as forced displacement and even political imprisonment of activists opposed to extraction.
