Restoring And Sustaining Smallholder Kappaphycus Alvarezii Farming Post-Typhoon Haiyan/Yolanda In Molocaboc, Central Philippines, David C. Fenlon Jan 2017

Restoring And Sustaining Smallholder Kappaphycus Alvarezii Farming Post-Typhoon Haiyan/Yolanda In Molocaboc, Central Philippines, David C. Fenlon

Dissertations, Master's Theses and Master's Reports

The farming of marine seaweed has the potential to provide both nutritional and financial resources to developing communities such as the Molocaboc Islands in the Philippines. To foster this mariculture development approximately $1,000 USD in grant funds received from the US-Philippines Society was used to purchase materials needed to replace seaweed production infrastructure lost to Typhoon Haiyan (known as Super Typhoon Yolanda in the Philippines). The goal was to restore and expand smallholder farming of the seaweed Kappaphycus alvarezii (locally known as ‘guso’ in the Visayan dialect) in the Molocaboc Islands, thereby increasing harvest yields as compared to those …


Critical Agrarian Studies In Theory And Practice, Marc Edelman, Wendy Wolford Jan 2017

Critical Agrarian Studies In Theory And Practice, Marc Edelman, Wendy Wolford

Publications and Research

Abstract: In this introductory article we argue for renewed attention to life and labor on and of the land—or what we call the field of Critical Agrarian Studies. Empirically rich and theoretically rigorous studies of humanity’s relationship to “soil” remain essential not just for historical analysis but for understanding urgent contemporary crises, including widespread food insecurity, climate change, the proliferation of environmental refugees, growing corporate power and threats to biodiversity. The article introduces an innovative and varied collection of works in Critical Agrarian Studies and also examines the intellectual and political history of this broader field.

Sustaining Uber: Opportunities For Electric Vehicle Integration, David Wagner Jan 2017

Sustaining Uber: Opportunities For Electric Vehicle Integration, David Wagner

Pomona Senior Theses

Uber and Lyft, the “unregulated taxis” that are putting traditional taxi companies out of business, are expanding quickly and changing the landscape of urban transportation as they go. This thesis analyzes the environmental impacts of Transportation Network Companies, particularly in California, with respect to travel behavior, congestion, and fuel efficiency. The analysis suggests that fuel efficient taxis are being replaced by less fuel efficient Uber and Lyft vehicles. Linear regressions were run on data from the Clean Vehicle Rebate Project’s Electric Vehicle Consumer Survey of electric vehicle owners in California. The findings indicate that Uber drivers are more reliant upon …


Lost Opportunities: Ecuador's Yasuní Itt Initiative, Julianna Hitchins Jan 2017

Lost Opportunities: Ecuador's Yasuní Itt Initiative, Julianna Hitchins

Pomona Senior Theses

In 2007, President Rafael Correa of Ecuador proposed the Yasuní ITT Initiative at the United Nations General Assembly in an effort to contribute to the reduction of carbon dioxide emissions and the local preservation of biodiversity. The initiative proposed enacting an indefinite ban on oil exploration and extraction within the Ecuadorian Yasuní National Park so long as the developed world was willing to contribute to half the forgone costs of drilling. However, despite initial support, the Yasuní Initiative was unsuccessful, and due to a lack of financial support, Correa terminated the proposal in August 2013.

The Effects Of Thermal Stress On Fluorescent Protein Expression In An Indo-Pacific Scleractinian Coral Species, Acropora Tenuis, Anna Knochel Jan 2017

The Effects Of Thermal Stress On Fluorescent Protein Expression In An Indo-Pacific Scleractinian Coral Species, Acropora Tenuis, Anna Knochel

Independent Study Project (ISP) Collection

The scleractinian coral species that so heavily define tropical coral reefs are increasingly threatened by anthropogenic global warming. Rising sea surface temperatures in combination with light stress causes the photosynthetic breakdown of the coral’s algal symbiont, Symbiodinium. Corals have developed a number of physiological responses to handle acute stressors, such as the production of ultraviolet-protecting amino acids, heat shock proteins, the ability to shift symbionts, and the production of fluorescent proteins. The latter has been thought to play a photoprotective role in the coral holobiont, and studies have shown evidence that corals orient these pigments to divert harmful light away …

International Lessons For The Future Spatial Direction For Ireland: Aspects Of Agglomeration And Their Influences On The Economic Role Of Cities, Brian Hughes

Conference papers

Ireland’s demography in the world context is unique. Its population count remains the same as it was some 200 years ago and yet it has experienced profound movements. This paper contrasts Ireland’s changing demography with that of Japan since the 1840’s, for these the two offshore nations, located off either end of the Eurasian land mass. Historic urban literature identifies that governmental policies towards cities and city-based industry and services appears to explain many of these contrasts. In Ireland’s case such policy both prior to and since the formation of the State has been an ambivalent one that has not …

Russell Lord And The Permanent Agriculture Movement: An Environmental Biography, Margaret L. Eppig Jan 2017

Russell Lord And The Permanent Agriculture Movement: An Environmental Biography, Margaret L. Eppig

Antioch University Dissertations & Theses

This work is an environmental biography of agricultural journalist Russell Lord and a history of the agricultural conservation organization he co-founded. Today the work of the Society for the Friends of the Land (1940 – 1960) is little known to contemporary agricultural and environmental history, yet its influence continues through the fields of sustainable agriculture and landscape restoration. This work chronicles how modern revolutions in scientific and ecological thought transformed the future of American agriculture. It formed the cornerstone of an emerging environmental movement. I argue that this movement, with Lord as its literary vanguard, was the lynchpin that bound …


From Disposable Culture To Disposable People: Teaching About The Unintended Consequences Of Plastics, Sasha Adkins Jan 2017

From Disposable Culture To Disposable People: Teaching About The Unintended Consequences Of Plastics, Sasha Adkins

Antioch University Dissertations & Theses

Plastics, the epitome of disposable culture, pose both a toxicological and a spiritual problem. This dissertation examines plastics at a molecular level using the discourse of endocrine disruption, and at a sociological level using the discourses of eco-theology and environmental justice. Adding to the literature on the adsorption of toxicants to plastic marine debris, I demonstrate that certain types of plastic -- those containing mercaptans, such as styrene butadiene block copolymer -- efficiently concentrate methyl mercury from seawater. Further, samples of polycarbonate contributed mercury to seawater. I propose the term plastic-mediated magnification to describe the phenomenon that plastics, along with …

First Nations And Adaptive Water Governance In Southern Ontario, Canada, Thomas Dyck Jan 2017

First Nations And Adaptive Water Governance In Southern Ontario, Canada, Thomas Dyck

Theses and Dissertations (Comprehensive)

Water quality and quantity are prominent concerns for First Nations across Canada. The federal government shares the responsibility with First Nations to ensure water resources on-reserves meet the needs of First Nations. Federal approaches have been predominantly technical, focused on addressing issues related to infrastructure, maintenance, training, and monitoring. This approach is important. However, water issues concerning First Nations go beyond technical issues and relate to inadequate participation in decision making, poorly defined roles and responsibilities, and approaches to managing water resources on-reserve that have not accounted for local context. These issues parallel historical nation-to-nation (i.e., First Nations and federal …
