Bioplastics In The Consumer Market, Elena Strom
Bioplastics In The Consumer Market, Elena Strom
Master of Science in Environmental Sciences and Management Projects
The global production and mismanagement of plastic has led to plastics deposited and scatted across marine environments. Conventional plastic, which most Americans encounter every day, is produced from fossil fuels and lacks the ability to fully break down upon disposal, breaking down into microplastics that can remain in the natural environment for hundreds of years. Moving away from petroleum-based plastics could lead to a reduction in greenhouse gas emissions and decrease plastic particles in the ocean. Based on existing literature, there are three biopolymers that could serve as replacements to conventional plastics in the marketplace. These biopolymers are seen as …
Climate Adaptation And Water Conservation Decision-Making In Paso Robles, California Vineyards, Christopher R. Klier
Climate Adaptation And Water Conservation Decision-Making In Paso Robles, California Vineyards, Christopher R. Klier
Master's Theses
This paper examines vineyard perceptions and adoption of climate change adaptation and water conservation measures in the Paso Robles American Viticultural Area (AVA). A survey was distributed to all 220 vineyards and vineyard management companies that operate in the AVA, with a 53.64% response rate. The objective of the survey was to determine vineyard manager and owner attitudes towards climate change and adaptation, as well as their perceptions of how these threats would impact their operation. A second objective was to document the current level of water conservation and climate adaptation while identifying the barriers and opportunities for further adoption …
A Comparative Review Of Cell-Based Mariculture And Conventional Seafood Life Cycle Assesments, Kyle Rathbone
A Comparative Review Of Cell-Based Mariculture And Conventional Seafood Life Cycle Assesments, Kyle Rathbone
Master of Science in Environmental Sciences and Management Projects
The global fishing and aquaculture industries inflict significant environmental impacts on our planet’s oceans. The overfishing, pollution, and environmental degradation currently caused by these industries threatens the sustainability of marine ecological and industrial systems. Despite this, demand for seafood is expected to rise in the coming decades to service the growing global population with nutrient-rich foods. The difficulty in reconciling the need for drastic improvements in marine sustainability and the need to continue meeting global seafood demand has produced an interest in alternative solutions to seafood production. The emerging cell-based foods industry may hold the potential to produce seafood products …
An Evaluation Of The Central Coast Rangeland Coalition: Trust And Other Factors Important For Collaborative Conservation, Dustin Tran
Master of Science in Environmental Sciences and Management Projects
The proliferation of collaborative partnerships across the western United States and the lack of tools and protocols to evaluate them have been well documented. As the number and types (conservation-based, policy actions, information sharing) of collaboratives rises, there is a need for research that aims to evaluate these partnerships' performance and collaborative process considering their importance and potential to solve complex ecological, economic, and social problems. This study aims to contribute to this pool of research by interviewing the Steering Committee (SC) members of the Central Coast Rangeland Coalition (CCRC), a volunteer-based and information-sharing rangeland collaborative coalition. We evaluate and …
A System Dynamics Model Of Soil Carbon Stock And Flows In Grasslands Under Climate And Grazing Scenarios., Deirdre Sommerlad-Rogers
A System Dynamics Model Of Soil Carbon Stock And Flows In Grasslands Under Climate And Grazing Scenarios., Deirdre Sommerlad-Rogers
Master's Theses
Carbon sequestration is paramount to reducing climate change. Grasslands, representing 40% of all terrestrial area, can serve as a primary sequestration location if optimal management strategies can be realized. This study used system dynamics modeling to examine the temporal dynamics of carbon stocks and flows in response to grass species composition, grazing intensity, and temperature and precipitation changes at the landscape level. While there are other biogeochemical models in existence, they are either meant to model large areas, including globally, or are meant to be at a farm level and have limited plot sizes, limiting the options for rangeland managers …
Soarnet, Deep Learning Thermal Detection For Free Flight, Jake T. Tallman
Soarnet, Deep Learning Thermal Detection For Free Flight, Jake T. Tallman
Master's Theses
Thermals are regions of rising hot air formed on the ground through the warming of the surface by the sun. Thermals are commonly used by birds and glider pilots to extend flight duration, increase cross-country distance, and conserve energy. This kind of powerless flight using natural sources of lift is called soaring. Once a thermal is encountered, the pilot flies in circles to keep within the thermal, so gaining altitude before flying off to the next thermal and towards the destination. A single thermal can net a pilot thousands of feet of elevation gain, however estimating thermal locations is not …
A Retrospective Analysis Of The Impact Of Wind Power Generation On Residential Natural Gas Prices In The United States, Maya Vikstrom
A Retrospective Analysis Of The Impact Of Wind Power Generation On Residential Natural Gas Prices In The United States, Maya Vikstrom
Economics
Heightened concern over the environmental impact and price volatility of natural gas has led to an increased demand for renewable energy. Wind energy is one of the fastest-growing sources of electricity and is the United States’ top renewable energy source. As a substitute for natural gas, wind energy has a direct impact on the demand for natural gas and consequently, the price. Using data from the U.S. Energy Information Administration, the Bureau of Economic Analysis, and the U.S. NOAA, this paper determines a causal relationship between wind generation and natural gas prices because of the random component of weather. Employing …
Comparing The Environmental Impacts Of Using Mass Timber And Structural Steel, Khang Hoang Nguyen, Steelee Knight Morgan
Comparing The Environmental Impacts Of Using Mass Timber And Structural Steel, Khang Hoang Nguyen, Steelee Knight Morgan
Construction Management
Although mass timber has seen a gradual rise in demand in the past, there has been a lack of extensive research on the environmental impacts of using mass timber as a primary structural framing material. This paper compares structural steel, and mass timber’s total embodied carbon emissions. Accurate estimates were made using plans and specs for different projects retrieved from semi-structured interviews. The estimates were input through the EC3 Calculator to provide extensive total carbon emissions measurements between each construction material. Using structural steel framing increased the project’s overall environmental impact by roughly 84% compared to using mass timber. The …
