Optimizing Solid Thermal Storage In Insulated Solar Electric Cookers, Stefan Avramov

Physics

Insulated Solar Electric Cookers, more commonly known by their acronym ISECookers, are an alternative to biomass cooking. The ISECooker in its simplest form is a solar panel connected to a heating element, in contact with a cooking pot in an insulated chamber. An aluminum puck can be heated as solid thermal storage (STS) for increased power and night time cooking. Power was limited to about 500 W by the interface between the STS and cookpot. Powdered graphite and silver were separately applied to increase thermal flow. However, the powdered graphite decreased the thermal flow, while powdered silver decreased the temperature …

Assessing Equity Of Green Infrastructure Strategies To Address Heat Vulnerability In Los Angeles Sustainable City Planning, Sophia N. La Herran

Master's Projects and Capstones

Urbanization has brought about many undesirable environmental changes, with extreme heat and urban heat island (UHI) effect being some of the most significant. In addition to the challenge of UHI effect and increase of extreme heat events, heat also disproportionately affects different types of urban populations with higher populations of minority and low-income residents, who are more exposed and have limited capacity to adapt to extreme. The increased vulnerability to heat faced by socially vulnerable communities can be linked to the inequalities in neighborhood level exposure to extreme heat events, underlying health conditions, workplace conditions, housing quality, and other lasting …

Sustainability Analysis: Large-Scale Desalination Implications For Coastal California, Elizabeth H. Whitford

Master's Projects and Capstones

In response to prolonged drought, desalination is gaining popularity as an alternative water production method for fresh water. However, water desalting technology poses concerns; the process is energy intensive, creates brine waste, and has the potential to damage sensitive coastal ecosystems. Significant research is available on the technological, economic, and energy efficiency aspects of desalination, while only a small percentage of the current literature focuses on environmental impacts. This research analyzes the desalination literature holistically in terms of both energy consumption and environmental impacts by conducting 1) a historical and current state review of the sector, 2) a technology analysis …

Increasing Access And Sustainability For Camping Along The Bay Area Ridge Trail, Hannah F. Bartee

Master's Projects and Capstones

The Bay Area Ridge Trail (Ridge Trail) is a long-distance, multi-use trail that connects parks and open space on the ridge lines encircling the San Francisco Bay (Bay). Like the Pacific Crest Trail and Appalachian Trail, the Ridge Trail offers continuous travel through protected natural areas, but this trail is unique as it is located in a densely populated metropolitan area. The trail is currently incomplete, with gaps where the trail does not connect. The Ridge Trail also lacks the number and distribution of overnight accommodations needed to support a full circumnavigation of the Bay. Addressing gaps in the current …

A Consumer's Guide To Greenwashing, Katie Fowler

Marketing Undergraduate Honors Theses

Over the past 37 years since the term greenwashing was coined, there have been sparse attempts to regulate this deceptive environmental marketing. The Federal Trade Commission (FTC) created its Guides for the Use of Environmental Marketing Claims, also known as the Green Guides, in 1992. The Guides have been revised on three separate occasions – 1996, 1998, and 2012 – in an attempt to remain relevant with the proliferation of environmental marketing claims and trends. However, the Guides were created as interpretive rules that do not give the FTC the authority to enforce the regulations unless they can prove that …

Potential Control Of Invasive Mesquite Through Improving The Consumer’S Understanding Of Liquid Smoke Applications., Seth W. Ellsworth

Graduate Theses and Dissertations

Mesquite trees continue to invade forests and range lands in many countries across the world. The cost to remove these trees is staggering. In Texas, landowners spent $25 million over a 10- year period to clear 300,000 ha of mesquite trees, a fraction of the 22 million ha of Texas land affected by this invasion. Estimates are that the mesquite continues to negatively impact one to two percent of additional land in selected counties each year in Texas. However, the problem is not unique to Texas, but rather to the 44 species of mesquite trees, belonging to the genus Prosopis …

Inner Mongolian Herders Move Toward Sustainability And Elevate Their Incomes From Cashmere Goat Production By Reducing Grazing Pressure On Fragile Grasslands, B. P. Fritz, M. Zhao

IGC Proceedings (1993-2023)

Overgrazing, mainly caused by Cashmere goats, is contributing to the desertification of West Erdos fragile grasslands resulting in the threat of extinction of several endangered wild plant species. This transition area between desert and grassland includes some 400,000 ha and some 72 unique, relic and endangered plant species. The area is home to 5,000 inhabitants, mainly subsistent goat farming families and coal mining activity. Industrial land use in the reserve adds additional economic pressure to herders operating on a shrinking land base. This phenomenon has elicited the entrenched, traditional response of producing more livestock thus jeopardizing current levels of production …

A Gravity Model Integrating Land-Use And Transportation Policies For Sustainable Development: Case Study Of Fresno, California, Chih-Hao Wang, Na Chen

Mineta Transportation Institute

The idea of urban compaction has been long proposed and promoted to address the problem of urban sprawl in many American cities. However, there are still rare successful cases of such implementation in the United States. This study uses a classic gravity model, TELEM (Transpiration, Economic, and Land-Use Model) to examine to what extent a land-use or transportation policy must be regulated to make the urban compaction occur in a typical auto-dependent city—Fresno, California. Five scenarios are considered (BL, L1, L2, T1, and T2), in which the baseline (BL) is a natural growth scenario. Without any policy interventions, the city …

Graduate, 2nd Place: Assessing The Knowledge, Attitude, And Everyday Life Practices Adopted Among Eastern Illinois University Students Towards Sustainability, Joel Holison

2023 Awards for Excellence in Student Research and Creative Activity - Documents

The concept of sustainable development gained attention and came into focus with the publication of the Brundtland Report (Brundtland, 1987). later the Education for Sustainability (EfS) initiative was presented in 1997 through the “Thessaloniki Declaration” as a carrier of the common and single message (Knapp, 2000). Sustainable development is the way a country pursues its economic development that does not jeopardize the opportunity for future generations to achieve their development (Brundtland, 1987). Deforestation, land destruction, soil degradation, air and water pollution, and other types of environmental deterioration are paid in the name of economic progress. This detriment may outweigh the …

A Decision Support System For Rangeland Management In Degrading Environments, R. G. Bennett, F. J. Mitchell

IGC Proceedings (1993-2023)

The continued viability and productivity of commercial and emerging agriculture in KwaZulu-Natal Province, South Africa, depends on the accurate assessment and sustainable utilization of available natural resources. Sustainability implies that growth and development must take place, and be maintained over time, within the limits set by natural ecosystems. Utilizing an extensive GIS database, field surveys and remote sensing technology, a land assessment decision support system (LADSS) has been developed in an attempt to define these limits for the Province. This system has been developed to assess the appropriate use of existing resources as well as the suitability of current land …

Australian Pasture Systems: The Perennial Compromise, L. W. Bell, M. A. Ewing

IGC Proceedings (1993-2023)

Dryland salinity, soil acidification and weed herbicide resistance challenge traditional agricultural production systems in south Australia. The pasture component of such systems rely on annuals like Trifolium subterraneum and Medicago spp. Replacing annual with perennial pastures allows some redress of the sustainability challenges, but few well-adapted species are available (Ewing & Dolling 2003). A range of perennial species are under evaluation to supplement current options. Some of these new perennial pastures may need modified production systems that allow full expression of their productive potential, especially when integrated with annual crops including cereals, pulses and oil seeds. Integrated systems rely on …

Precious Plastics - Plastic Brick Machine Fabrication, Timothy Ukaobasi Kanu, Evi Paraskevi Troulis

Architectural Engineering

The goal of this research is to determine the structural parameters of the recycled plastic polypropylene when molded into bricks resembling CMU blocks. To accomplish this, three mechanisms had to be assembled: the shredder, the injector, and the 1x1 mold. A tensile and compression test were to be performed on the plastic brick, and the values would be used to compare the tensile and compressive strength of PP plastic bricks, as well as their modulus of elasticity and stress vs. Strain performance. These values would be analyzed to determine whether it would be feasible to build an entire plastic wall. …

What Research Is Required For Economically And Environmentally Sustainable Farming?, W. Taylor

IGC Proceedings (1993-2023)

This Congress is being held on an island that is a Nitrate Vulnerable Zone. No other land area in the western world has achieved such a status!

With this designation come completely new parameters for agriculture in general and grassland production in particular. Alongside this change in emphasis for the grass based industry is the implementation of the Common Agricultural Policy reform. For farming within the European Union it is not completely about maximising production, about “growing two blades of grass where one grew before”. It’s also about creating a diverse landscape, about less pollution about greater recreational opportunities, about …

Grassland Research: Goals For The Future, J. R. Roche

IGC Proceedings (1993-2023)

Our goal as scientists must be to provide sufficient food for the world’s population, while returning sufficient income for effort to the food producer. It has been established elsewhere in the conference that pasture-based systems can return high milk production per hectare at low input cost, but are limited to highly fertile, temperate regions with evenly dispersed rainfall patterns and moderate maximum and minimum temperatures. There should be two goals of grazing research in the future; to sustain or improve the profitability of current grazing production systems, and to develop plant and animal varieties that allow grazing in currently less …

Fossil Fuel Divestment In U.S. Higher Education: Endowment Dependence And Temporal Dynamics, Alexander R. Barron, Rachel C. Venator, Ella V.H. Carlson, Jane K. Andrews, Junwen Ding, David Deswert

Environmental Science and Policy: Faculty Publications

Since 2012, students and others have pushed U.S. Higher Education Institutions (HEIs) to divest their endowments from fossil fuel producing industries. In the past decade, fossil fuel divestment has become the fastest growing divestment movement in history, with over 140 U.S. HEIs announcing divestment commitments. We conduct a quantitative analysis of the three phases of U.S. 4-year HEI divestment announcements (as well as rejections of divestment) to better understand the dynamics. Announcements began (2012-2017) with a number of schools divesting, followed by a second phase where new divestment announcements slowed. The current phase, which began around 2019, shows a renewed …

Assessing The Effectiveness Of Integrated Multi-Trophic Aquaculture For Growing West Coast Venus Clams, Avery Wallace

Theses

With demand for sustainable sources of seafood on the rise, California is looking to expand aquaculture with a focus on innovative culturing methods and use of native or resident species. Therefore, this study examined the potential for culturing native North American west coast venus clams (Chione californiensis and Chione undatella) using integrated multi-trophic aquaculture (IMTA). An ITMA approach was chosen because it is a culture method that uses species from different but functionally complementary trophic levels that have been found to reduce the potential negative effects of traditional monoculture. California sea cucumber (Parastichopus californicus) and the seaweeds red ogo (Gracilaria …
