Quantifying The Carbon Stored And Sequestered By The Trees On Pomona College’S Campus, Paola A. Giron-Carson

Scripps Senior Theses

We are experiencing a climate crisis that must be confronted with strategic mitigation. Pomona College contributes to the climate crisis through its emissions for which there is a baseline record. However there is no baseline record of the climate mitigation currently performed by the trees on Pomona’s campus through carbon storage. This study seeks to determine a current baseline quantity of carbon stored and sequestrated by Pomona’s trees as well as possible courses of climate mitigation for Pomona College to take. Initial information gathering was conducted through interviews with several stakeholders. This study was conducted using data collected prior to …


Intercropping For Water Conservation: Environmental And Economic Implications Of A Sustainable Farming Practice In California's Central Valley, Sophie Baker Jan 2020

Intercropping For Water Conservation: Environmental And Economic Implications Of A Sustainable Farming Practice In California's Central Valley, Sophie Baker

Scripps Senior Theses

California’s agricultural sector is the biggest water consumer in the state and faces intense pressure to reduce its overall water usage. Industrialized monoculture systems dominate the industry and often disregard long-term environmental and economic externalities for short-term profit maximization. To maintain longstanding food security and economic stability as well as protect the state’s water supply, it is critical that these systems transition to more sustainable and resilient production mechanisms. As an alternative to monoculture, intercropping affords greater potential to conserve water, protect soil quality, and increase crop yields, among other metrics of sustainability. However, there has been much controversy over …


Shrimp Farming In Thailand: A Pathway To Sustainability, Warinyupa Phornprapha Jan 2020

Shrimp Farming In Thailand: A Pathway To Sustainability, Warinyupa Phornprapha

Pomona Senior Theses

Throughout this thesis I have laid out several factors that have contributed to the sustainability of shrimp farming in Thailand, and if sustainability whilst maintaining production can ever be achieved. To find out the current situation of shrimp farming in Thailand, the history of global and Thai shrimp farming is described. The social and environmental problems of the unsustainable history of shrimp farming in Thailand is then considered. Solutions to these effects conclude that it is up to the consumer to demand for better regulations from the government and the shrimp companies to ensure a sustainable future for shrimp farming …


Island Invasion: The Silent Crisis In Hawaii, Sophia Janssen Jan 2019

Island Invasion: The Silent Crisis In Hawaii, Sophia Janssen

Pomona Senior Theses

Keeping out invasive species may, upon first review, seem like a trivial environmental cry from ecologists and deep environmentalists; a belated wish to return to an undeveloped world where nature was pristine. However invasive species create problems that impact all of us and can have far more severe consequences than changing a stunning landscape. These problems are heightened in islands like Hawaii, where the fragile ecosystems have developed over centuries of evolution and adaptation. The introduction of a disease-carrying mosquito can put the people of Hawaii at risk to many vector-born illnesses and create an epidemic, taking human life. The …


Colonialism And Its Aftermaths In Vieques, Puerto Rico: How U.S. Hegemony Led To Contamination, A Superfund Site, And Local Mistrust, Kaya Mark Jan 2018

Colonialism And Its Aftermaths In Vieques, Puerto Rico: How U.S. Hegemony Led To Contamination, A Superfund Site, And Local Mistrust, Kaya Mark

Scripps Senior Theses

After sixty-two years of U.S. military testing, the small Puerto Rican island of Vieques and its residents continue to fight against ongoing environmental and social effects of U.S. hegemony. Starting with the arrival of the Spanish, then with U.S. occupation and use of Vieques as a military stopover, Viequense residents are used to U.S. governmental presence on their land. Despite the military’s removal from Vieques in 2003, many local residents have a fundamental lack of trust for the U.S. government. Because of this lack of trust and transparency with U.S. governmental actions in the post- World War II period, residents …


Sustainability-Efficiency Paradox: The Efficacy Of State Energy Plans In Building A More Sustainable Energy Future, Austin Zimmerman Jan 2018

Sustainability-Efficiency Paradox: The Efficacy Of State Energy Plans In Building A More Sustainable Energy Future, Austin Zimmerman

Pitzer Senior Theses

State energy plans are created at the request of a sitting governor or State Legislature in order to provide guidance set goals for the state’s energy sector. These plans will be critical indicators of energy trends such as the future market share of coal, natural gas, and renewables. If the future of energy in the United States is to be remotely sustainable, low-carbon policies must headline state plans. The strength of a state’s energy plan in terms of sustainability is directly related to that state’s willingness to prioritize and commit to incorporating energy sources that produce negligible carbon emissions. Questions …


Stormwater Capture In The Built Watershed: Fostering Public Awareness Of Water Conservation Through A Parcel-Level Approach To Stormwater Management, Benjamin Rigby Jan 2018

Stormwater Capture In The Built Watershed: Fostering Public Awareness Of Water Conservation Through A Parcel-Level Approach To Stormwater Management, Benjamin Rigby

Pitzer Senior Theses

As California contends with climate change and more extreme cycles of drought and deluge, water management agencies and conservation groups are looking towards solutions to the decreasing reliability of imported water supplies. Stormwater has historically been perceived as a threat to development but when captured properly, it presents a resource that can augment local water supplies. Solutions to water supply issues in California have traditionally employed technical and centrally controlled methods for importing water, but there is a growing understanding that parcel-level capture through vegetated swales presents an opportunity for reducing the impact that development has on California’s hydrology. Vegetated …


One View: Fire Fuels Regeneration In Eastern Sierra, Char Miller Jun 2016

One View: Fire Fuels Regeneration In Eastern Sierra, Char Miller

Pomona Faculty Publications and Research

Sometimes it’s the small things that can best tell big stories.

Like the Marina Fire, which currently has burned a modest 800 acres to the north of Lee Vining, threatened but did not burn any structures, and whose greatest disruption has been periodically to shut down US 395. It hardly seems worth much attention.


Malheur Occupation In Oregon: Whose Land Is It Really?, Char Miller Jan 2016

Malheur Occupation In Oregon: Whose Land Is It Really?, Char Miller

Pomona Faculty Publications and Research

The Malheur National Wildlife Refuge, a 187,757-acre haven for greater sandhill cranes and other native birds in eastern Oregon, is usually a pretty peaceful place. But its calm was shattered on Saturday, January 2 when Ammon Bundy and a group of armed men broke into and occupied a number of federal buildings on the refuge, vowing to fight should the government try to arrest them. Their insurrectionary goal appears to be, simply put, to destroy the national system of public lands – our forests, parks and refuges – that was developed in the late 19th century to conserve these …

The special project is geared to design and present a new paradigm to integrate college education, scholarship, and service. The relevance of the initiative and the special project to STEAM education is discussed.


Ensuring Our Future Or Sowing The Seeds Of Our Own Destruction? Crop Insurance And Water Use In Texas, Michael Shapiro Jan 2015

Ensuring Our Future Or Sowing The Seeds Of Our Own Destruction? Crop Insurance And Water Use In Texas, Michael Shapiro

Pomona Senior Theses

Agriculture is the largest consumer of water in the United States. Policies that affect agriculture therefore have the potential to have a large effect on the overall use of water. Crop insurance is one such policy, which was found to significantly increase water use in the state of Texas. Much, but not all of this effect can be explained by an increase in planting density, and results vary widely by crop and by region.


The Future Of Squaw Valley And Alpine Meadows, Brian Friel Jan 2015

The Future Of Squaw Valley And Alpine Meadows, Brian Friel

Pomona Senior Theses

This paper examines the ongoing conflict between Squaw Valley Ski Holdings and the local Tahoe community and analyzes this conflict within the greater historical context of ski resort consolidation and development across the Western United States.


Reforestation, Renewal, And The Cost Of Coal: Opposing A Manichean Worldview In Central Appalachia, Elizabeth R. Hansen Jan 2015

Reforestation, Renewal, And The Cost Of Coal: Opposing A Manichean Worldview In Central Appalachia, Elizabeth R. Hansen

Pomona Senior Theses

Surface coal mining is a major form of land change and environmental degradation in Central Appalachia. Traditional mine reclamation iresults in unmanaged, unproductive grasslands that fail to mitigate many of the environmental costs of coal mining and are of minimal use to communities. Forestry reclamation is an alternative reclamation tactic that has the potential to address both environmental and socioeconomic concerns in Central Appalachia. A case study of Laurel Fork Mine in Eastern Kentucky is included.


San Diego’S Options For Alternate Sources Of Water: A Comparative Analysis Of Water Recycling And Desalination As Alternative Methods To Importing Water, Alana O. Pokorny Jan 2015

San Diego’S Options For Alternate Sources Of Water: A Comparative Analysis Of Water Recycling And Desalination As Alternative Methods To Importing Water, Alana O. Pokorny

Scripps Senior Theses

This paper describes the processes, methods, backgrounds, and economic challenges, of Desalination and Water Recycling and provide current examples of both. To create a baseline with which to compare the two methods, I will also delve into the history of California water policy. This complicated past is the reason water importation into Southern California remains the main method of obtaining water. Yet, as the current drought continues and technology advances, the need for imported water will become obsolete as the methods for recycling and desalinating water become less expensive, more convenient and more equitable. In the conclusion, all the methods …


Changing The Climate Narrative: How A Long-Term Climate Change Might Save Our Lives, Natalie P. Harreld Jan 2014

Changing The Climate Narrative: How A Long-Term Climate Change Might Save Our Lives, Natalie P. Harreld

CMC Senior Theses

The goal of this paper is to offer new insights into the climate change debate by shifting away from the heated anthropologic arguments that dominate politics, media, and popular science. Instead, I choose to rely on the long-term impacts of a changing climate on our planet. The paper begins with a break down of key processes involved in short-term and long-term climate change, using the latest research. After a foundational understanding of climate sciences is established, we will discuss the failure of the climate change debate in educating the general public about the facts of a changing climate. Finally, the …


A Policymaker's Guide To Feed-In Tariffs: Encouraging A Responsible Transition To Renewable Electricity In California, Roland P. Thayer May 2013

A Policymaker's Guide To Feed-In Tariffs: Encouraging A Responsible Transition To Renewable Electricity In California, Roland P. Thayer

Pomona Senior Theses

The feed-in tariff is a flexible, yet effective mechanism in promoting the proliferation of renewable electricity in California. The tariff creates a stable investment environment that protects both the utilities and the renewable electricity generators. Not only does the system foster capacity growth, but also technological advancement to the point where renewable electricity can compete in the market without assistance. From an environmental standpoint, the feed-in tariff contributes significantly towards achieving the emissions reduction goals set forth by AB32 without causing harmful increases to electricity prices.

The feed-in tariff model has been used in countries all over the world and …


The Full Cost Of Renewables: Managing Wind Integration Costs In California, William Savage May 2012

The Full Cost Of Renewables: Managing Wind Integration Costs In California, William Savage

Pomona Senior Theses

Wind power will be an important component of California's aggressive strategies to meet its greenhouse gas reduction targets by the year 2020. However, the costs of integrating wind power's variable and uncertain output are often ignored. I argue that California must take prudent action to understand, minimize, and allocate wind integration costs. A review of numerous studies suggests that for wind penetration levels below 20%, integration costs should remain modest. However, costs are heavily dependent on market structure, and I suggest numerous ways that California can optimize its market design to manage wind integration costs.


Arsenic Contamination In Groundwater In Vietnam: An Overview And Analysis Of The Historical, Cultural, Economic, And Political Parameters In The Success Of Various Mitigation Options, Thuy M. Ly May 2012

Arsenic Contamination In Groundwater In Vietnam: An Overview And Analysis Of The Historical, Cultural, Economic, And Political Parameters In The Success Of Various Mitigation Options, Thuy M. Ly

Pomona Senior Theses

Although arsenic is naturally present in the environment, 99% of human exposure to arsenic is through ingestion. Throughout history, arsenic is known as “the king of poisons”; it is mutagenic, carcinogenic, and teratogenic. Even in smaller concentrations, it accumulates in the body and takes decades before any physical symptoms of arsenic poisoning shows. According to the World Health Organization (WHO), the safe concentration of arsenic in drinking water is 10 µg/L. However, this limit is often times ignored until it is decades too late and people begin showing symptoms of having been poisoned.

This is the current situation for Vietnam, …


Aquculture And Deforestation In The Peruvian Amazon, Gator Halpern May 2012

Aquculture And Deforestation In The Peruvian Amazon, Gator Halpern

Pomona Senior Theses

This study examines whether aquaculture has the potential to reduce deforestation in the Peruvian Amazon. The natural resources of the Peruvian Amazon are subject to extreme pressures due to increases in subsistence farming, cattle ranching, and logging in the region. The resulting loss of biodiversity has affected the delicate soil balance that is characteristic of the Amazon, and has contributed to water pollution as well as erosion (Guerra et al. 2001). One of the highest rates of deforestation in the Amazon basin can be found at the foothills of the eastern Andes (Lepers et al. 2005), which includes the area …


Sediment Removal From The San Gabriel Mountains, Mary C. Ferguson May 2012

Sediment Removal From The San Gabriel Mountains, Mary C. Ferguson

Pitzer Senior Theses

The issue of sediment removal from the San Gabriel Mountains has been a complex issue that has created problems with beach replenishment, habitat destruction and the need to spend millions of dollars at regular intervals to avoid safety hazards. Most recently 11 acres of riparian habitat, including 179 oaks and 70 sycamores, were removed for sediment placement. Other sites including Hahamongna Watershed Park and La Tuna Canyon also face a similar fate. This thesis questions: How did we get to this point of destroying habitat to dump sediment which is viewed as waste product? What are the barriers for creating …

Overcoming The Obstacles To Sustainability In Ghana, Ashley M. Scott Jan 2011

Overcoming The Obstacles To Sustainability In Ghana, Ashley M. Scott

CMC Senior Theses

For several decades following its independence from Great Britain, Ghana’s policies continued to promote over-extraction of natural resources to the detriment of its economy and rural communities. Agricultural and forestry policy has gradually evolved to foster more sustainable and equitable practices, as in building partnerships with the private sector to fund infrastructure improvements. Policy has recently recognized the dire need to adopt agricultural practices and means of forest resource extraction that are compatible with ecological stewardship. However, many shortcomings are still apparent. Large logging operations completely disregard forestry regulations with impunity, whereas rural sustenance extractors are severely punished in the …


Effective Environmental Management Of The National Park Service: A Case Study Of Channel Islands National Park, Daniel T. Olmsted Jan 2010

Effective Environmental Management Of The National Park Service: A Case Study Of Channel Islands National Park, Daniel T. Olmsted

CMC Senior Theses

The topic of protected area management serves as the focal point of my thesis. The fundamental question I seek to answer is; what constitutes effective environmental management and how is it exemplified in the National Park Service (NPS)? How exactly does the NPS continually earn the trust and confidence of the American people when so many other government agencies are viewed in a negative light? How does the Channel Islands National Park, in particular, shape the economic and political framework in which it operates to achieve its goals? How does this agency effectively manage such a complex ecosystem spanning across …

Sustainability Reporting At Higher Education Institutions, Robert Heilmayr Jan 2006

Sustainability Reporting At Higher Education Institutions, Robert Heilmayr

CMC Senior Theses

Multiple declarations, governmental and non-profit organizations and universities have issued a call for proper reporting of social and environmental impacts and initiatives within academia. Such reporting can increase awareness of environmental and social impacts, encourage development of sustainable policy and build a campus culture more committed to sustainability. Sustainability reporting at Higher Education Institutions (HEIs) has the added benefit of being a powerful teaching aid. This paper follows multiple lines of inquiry in order to determine whether HEIs are taking advantage of the opportunities afforded by sustainability reporting. The analysis evaluates the history of sustainability reporting at HEIs and compares …


Hawaiians Fight For The Rainforest, Paul Faulstich May 1990

Hawaiians Fight For The Rainforest, Paul Faulstich

Pitzer Faculty Publications and Research

On March 25, 141 were arrested as part of the largest demonstration yet against the drilling of geothermal wells in the Wao Kele O Puna Rainforest on the Big Island of Hawaii. The geothermal project, undertaken by True Geothermal Company and endorsed by Hawaii's governor and other high-powered, short-sighted people, has already invaded the largest intact tropical lowland rainforest in the United States. The demonstration drew over 1500 protesters,
