Power Play: The President's Role In Shaping Renewable Energy Regulation And Policy, Luke Bartol
Honors Projects
With the impacts of climate change becoming more and more apparent every day, finding means of effective action to mitigate its effects become increasingly critical. While localized work can play an important role, federal action is necessary to have the most widespread and effective impact, especially on interconnected issues such as clean energy. Congressional action is the avenue of change at this level, however in an increasingly partisan and divided environment, progress on this front is far short of what is needed.
Looking to the president is logical here, both as a single actor more insulated from partisan fights, but …

24/7 Clean Energy, Todd Aagaard
24/7 Clean Energy, Todd Aagaard
University of Colorado Law Review
In the face of the rapidly escalating climate crisis, the electricity sector is moving toward renewable energy. To date, policies and strategies have focused on increasing overall renewable energy generation, with little regard for timing and location. The result has been a misalignment of supply and demand in renewable energy markets. Renewable power projects produce energy when and where it is least expensive, leaving supply scarce at other times and places. Consumers, meanwhile, continue to use power when and where they need it. This mismatch increases the electricity grid’s dependence on fossil fuel–fired electricity to meet electricity demand at times …

Trademark's Grip Over Sustainability, Daniel R. Cahoy
University of Colorado Law Review
Entrepreneurs and larger firms are waking up to the fact that there is a viable market for recycled, repaired, and even upcycled goods. There is also an increasing desire on the consumer end for more sustainable products as well as measures to reduce landfill and other product disposal harms to the environment. Although some legal barriers to this new market are being actively debated, other barriers have taken a back seat and seem primed to surge only when increased business activity exposes the liability. This is the case with trademark law, which has the potential to substantially deter the small-firm …

Polytech To Polytek: Traditional Ecological Knowledge, Indigenous Science, And The Future Forward Polytechnic University, Cutcha Risling Baldy, Kaitlin P. Reed, Kayla Begay
Humboldt Journal of Social Relations
It is clear from Cal Poly Humboldt’s Polytechnic Prospectus that Traditional Ecological Knowledge (TEK) and Indigenous communities are key parts of what elevates Humboldt’s development of a polytechnic university for the next century. The prospectus demonstrates Humboldt's proposed framework for a different comprehensive polytechnic "will also be informed by Indigenous communities and ways of knowing, as many Native peoples have lived sustainably in their places since time immemorial” (19). There are many considerations when engaging with TEK, especially around sustainable use. It is also important that engagement with TEK and Indigenous science not only center knowledge sharing, but also how …

Middle Savannah River: An A/R/Tographic Ecopedagogical Ethnography Experimenting With Rhizomatic Perspectives, Lisa Augustine-Chizmar
Electronic Theses and Dissertations
This research is an experiment in perspective. Using the four commonplaces (Schwab, 1978), I practiced letting the Savannah River teach me what there is to know about the water, the land, the people, and the other entities that depend on ki through artistic, ethnographic, and ecopedagogical lenses. The ethnographic findings describe the social actors that depend on ki and give a voice to the River. The a/r/tographic findings display the River on a canvas map through two hundred years using paint, clay, photography, video, abstract acrylics, and fabric. Together, these methods contribute to a unique ecopedagogical journey. This word cloud …

Climate Justice In The Anthropocene And Its Relationship With Science And Technology: The Importance Of Ethics Of Responsibility, Paolo Davide Farah, Alessio Lo Giudice
Articles
Climate change is a global phenomenon. Therefore, globalization is the necessary hermeneutical horizon to develop an analysis of the metamorphosis climate change could cause at a political, social, and economic level. Within this horizon, this Article shows how the relationship between the concept of the Anthropocene epoch and the request for justice allows for framing a climate-justice and intergenerational equity–focused political interpretation of the effects of climate change. In order to avoid reducing such an interpretation to merely an ideological critique of capitalism, the conception of climate justice needs to be grounded in a rational, ethical model. This Article proposes …

Hydrologic Outcomes For Ecological Meadow Restoration In The Northern Sierra Nevada, Emma Sevier
Hydrologic Outcomes For Ecological Meadow Restoration In The Northern Sierra Nevada, Emma Sevier
Cal Poly Humboldt theses and projects
Ecologically functioning meadows provide critical ecosystem services including improving a catchment’s water yield, flood dispersion and attenuation, fostering groundwater-dependent ecosystems, and creating natural fire breaks (Loheide and Booth 2011). Degradation from past and current land use has resulted in incised channels that change the magnitude and timing of watershed and meadow fluxes and cause water table decline. Process-based restoration (PBR) is an approach which leverages fluvial processes to increase restoration efficiency. Though PBR is a promising tool to restore degraded meadow ecosystems, more studies are needed to understand its hydrologic outcomes and whether hydrodynamic modeling can be used as a …

Macrolichen Inventory Of The Horse Mountain Botanical Area, Six Rivers National Forest, California, Usa, Sarah Norvell Conway
Cal Poly Humboldt theses and projects
Macrolichen diversity and community composition was determined for an area of high botanical interest in the Coast Ranges of Northern California – the Horse Mountain Botanical Area (HMBA) in Six Rivers National Forest. The Coast Ranges have been suggested to have high epiphytic macrolichen diversity, yet detailed site-specific macrolichen surveys are lacking for the area. Here we present comprehensive data on macrolichens of the HMBA integrated with environmental metadata at the landscape level. Twenty 0.4 ha sampling plots were positioned across the varying habitats of the HMBA and macrolichens were intensively sampled from all substrata. Out of 888 total collections, …

The Effects Of Post-Harvest Residue On Plantation Forest Soils And Early Growth Of Redwood And Douglas-Fir Seedlings In Humboldt County California, Robert W. Raibley
Cal Poly Humboldt theses and projects
Forest harvest residue (slash) usefulness has been up for debate among private timberland owners, public land managers, and the timber industry for decades. The disposal of slash, viewed as having low ecological value, has received considerable attention as wildfire risk has made burning it harder. In recent years, forest scientists and ecologists have recognized the importance of decaying wood and its relationship to forest growth and regeneration. At this site in Northern California, we looked at whether forest harvest residue enriches soil near slash windrows through soils coring and lab analyses, looking for primary limited nutrients nitrate (NO3-N) …

Food Waste Storage Gaseous Emissions Detection And Quantification Using Infrared Spectroscopy, Ryley A. Burton-Tauzer
Cal Poly Humboldt theses and projects
A growing interest in sustainable waste management and the implementation of new policies have prompted a shift towards alternative resource recovery methods for organic waste, including food waste. To effectively assess alternative food waste treatment scenarios, it is important to evaluate the life cycle impacts associated with each scenario. The storage phase of food waste, encompassing its accumulation in kitchens, and storage in bins for collection and transportation, has been overlooked as a source of greenhouse gases in previous studies. This investigation aimed to identify the greenhouse gases emitted during the initial five-day period of low-oxygen storage. An open dynamic …

Occurrence Of Per- And Polyfluoroalkyl Substances (Pfas) In New Hampshire Biosolids, Katherine A. Wieck
Occurrence Of Per- And Polyfluoroalkyl Substances (Pfas) In New Hampshire Biosolids, Katherine A. Wieck
Honors Theses and Capstones
Per- and polyfluoroalkyl substances (PFAS) are a group of over 4,000 compounds used in the manufacturing of products including aqueous film forming foams for firefighting, stain repellents, waterproofing agents, and nonstick cookware since their initial development in the 1940s. The long fluorinated carbon chain structure of PFAS causes chemical and thermal stability, and thus resistance to biodegradation. Biosolids produced at wastewater facilities for uses such as agricultural land-applied compost and fertilizer for lawns and athletic fields, as well as sludge disposed in landfills can cause contamination of groundwater and surface water. This poses a significant threat to human and environmental …
