Various tools and methods are used in participatory modelling, at different stages of the process and for different purposes. The diversity of tools and methods can create challenges for stakeholders and modelers when selecting the ones most appropriate for their projects. We offer a systematic overview, assessment, and categorization of methods to assist modelers and stakeholders with their choices and decisions. Most available literature provides little justification or information on the reasons for the use of particular methods or tools in a given study. In most of the cases, it seems that the prior experience and skills of the modelers …

Residential Zoning And Near-Roadway Air Pollution: An Analysis Of Los Angeles, C. J. Gabbe

Environmental Studies and Sciences

Air pollution from motor vehicles harms the health of those who live near freeways and other high-traffic roads. Land use regulations may permit, prohibit, or impose special conditions on housing near major roadways. This paper answers two questions: First, how is residential development near major roadways regulated? Second, how common are zoning changes near major roadways, and what factors explain these changes? This paper compares the zoning designations of near-roadway parcels with others in the city, and uses two sets of logistic regression models to analyze near-roadway zoning. The results show that residential development is permitted on most near-roadway parcels, …

"Waste Is Not Just Waste Anymore": Deconstructing The Relationship Between Sustainable Waste Prevention And Individual Socio-Demographic Characteristics (The Juxtaposition Of Ushongo Mtoni Village And Moshi Urban, Tanzania), Mahalia Smith

Independent Study Project (ISP) Collection

I am going to tell you a story about humans — their lives, livelihoods, environments, and their individual relationships to sustainable waste prevention. As developing countries, such as Tanzania experience economic growth, waste overflow and proper waste disposal become even more arduous challenges. Thus, it is becoming increasingly important to explore sustainable solutions such as waste prevention. Through conducting semi-structured interviews in two distinctly unique locations, Moshi Urban of the Kilimanjaro Region and Ushongo Village on the coast of Tanga Region, Tanzania, I explored how levels of awareness and involvement in sustainable waste prevention practices, specifically reducing, reusing, and recycling, …

Garden Pollinators And The Potential For Ecosystem Service Flow To Urban And Peri-Urban Agriculture, Gail A. Langellotto, Andony Melathopoulos, Isabella Messer, Aaron Anderson, Nathan Mcclintock, Lucas Costner

Urban Studies and Planning Faculty Publications and Presentations

Hedgerows, flowering strips, and natural areas that are adjacent to agricultural land have been shown to benefit crop production, via the provision of insect pollinators that pollinate crops. However, we do not yet know the extent to which bee habitat in the form of urban gardens might contribute to pollination services in surrounding crops. We explored whether gardens might provision pollinators to adjacent agricultural areas by sampling bees from gardens in the Portland, Oregon metropolitan area, and estimating typical foraging distances in the context of commercialand residential-scale pollination-dependent crops up to 1000 m from garden study sites. We estimate that …

The Role Of The Local Community On Federal Lands: The Weaverville Community Forest, Erin C. Kelly

Humboldt Journal of Social Relations

In the wake of the timber wars, communities across the American West have struggled to redefine their relationships to nearby federal forests. The timber-dependent model of the pre-Timber War era, with clear timber targets and economic outputs, has been replaced by more nuanced and less clearly-defined model: ecosystem management. This case study research uses interviews with participants in the Weaverville Community Forest (WCF) to explore the role of a community in managing its nearby federal lands. Momentum for the WCF flowed from a small group of citizens who were invested in the forest despite their cultural and ideological differences regarding …

Beyond 'Owls Versus Jobs': A Twenty-Year Retrospective Of The Headwaters Forest Controversy, Jennifer Bernstein

Humboldt Journal of Social Relations

In 1999, the Headwaters Forest Reserve was established in Humboldt County after more than 20 years of community activism, negotiations, and litigation. The ‘last stand’ of unprotected, privately-owned old growth redwood had finally been safeguarded, though many on the North Coast felt that the final deal fell far short of what was needed to protect the watershed’s ecological functioning. This article uses academic and journalistic research, supplemented by oral histories, to make three main points about the North Coast ‘post deal.’ One, forest management practices in the region have evolved to be more consistent with the practices of ecological forestry. …

Morphological And Histological Description Of Small Metoposaurids From Petrified Forest National Park, Az, Usa And The Taxonomy Of Apachesaurus, Bryan M. Gee, William G. Parker

United States National Park Service: Publications

Metoposaurids are Late Triassic temnospondyls that are abundant components of freshwater deposi- tional settings. Although metoposaurids are represented by hundreds of specimens in collections around the world, the vast majority pertain to large-bodied, relatively mature individuals, and as a result, the early stages of ontogeny are still poorly characterised. Small-bodied metoposaurids from North America have traditionally been assigned to Apachesaurus gregorii, interpreted as a diminutive taxon, but this interpretation has not been rigorously tested. Here we provide a morphological description of two new small-bodied metoposaurid specimens from Petrified Forest National Park, AZ, USA. Both provide various anatomical details that improve …

Radical Social Ecology As Deep Pragmatism: A Call To The Abolition Of Systemic Dissonance And The Minimization Of Entropic Chaos, Arielle Brender

Student Theses 2015-Present

This paper aims to shed light on the dissonance caused by the superimposition of Dominant Human Systems on Natural Systems. I highlight the synthetic nature of Dominant Human Systems as egoic and linguistic phenomenon manufactured by a mere portion of the human population, which renders them inherently oppressive unto peoples and landscapes whose wisdom were barred from the design process. In pursuing a radical pragmatic approach to mending the simultaneous oppression and destruction of the human being and the earth, I highlight the necessity of minimizing entropic chaos caused by excess energy expenditure, an essential feature of systems that aim …

Speleogenetic Evolution And Geological Remote Sensing Of The Gypsum Plain, Eddy County, New Mexico, Jessica Shields

Electronic Theses and Dissertations

Permian evaporites of the Gypsum Plain region of the Delaware Basin host extensive karst phenomena, as well as unique diagenetic alterations of host strata. Because of the complex, poorly understood hydrogeologic system, little has been established concerning the relation and evolution of the overprinted, modern and ancient karst manifestations within the Gypsum Plain, as a whole. Through a combination of traditional field studies and the development of improved remote sensing methodologies, this study established the speleogenetic evolution of the Gypsum Plain in relation to the greater tectonic, stratigraphic, hydrogeologic and climatic history of the Delaware Basin. Emphasis was focused on …

Science, Advocacy, Policy, Planning: Tools For Advancing Transportation Equity, Garrett S. Mcallister

Graduate Student Portfolios, Professional Papers, and Capstone Projects

The theme of this portfolio is how different tools and approaches can be used for advancing transportation equity. Broadly defined, transportation equity is about fairness in transportation. There are a number of ways this fairness can be assessed. The most common way to assess transportation equity is by looking at the fairness of outcomes, distributed geographically, socially, or even by mode of transportation. Equity can also be defined by the fairness of processes. The first half of the portfolio illustrates some of the problems with the current transportation system and how it is unhealthy (Piece 1) and unjust (Piece 2). …

Testing Methods To Mitigate Caribbean Yellow-Band Disease On Orbicella Faveolata, Carly J. Randall, Elizabeth M. Whitcher, Tessa Code, Clayton Pollock, Ian Lundgren, Zandy Hillis-Starr, Erinn M. Muller

United States National Park Service: Publications

Outbreaks of coral diseases continue to reduce global coral populations. In the Caribbean, yellow band is a severe and wide-spread disease that commonly affects corals of the Orbicella spp. complex, significantly impeding coral reproduction, and hindering the natural recovery of Orbicella spp. populations. Caribbean yellow-band disease (CYBD) lesions may be severe, and often result in the complete loss of coral tissue. The slow spread of CYBD, however, provides an opportunity to test methods to mitigate the disease. Here we report the results of in situ experiments, conducted within Buck Island Reef National Monument in St. Croix, USVI, to test the …

A Socioeconomic Valuation Of Urban Wetland Ecosystems And Policy Recommendation For College Lake, Michael Dunmyer

Undergraduate Theses and Capstone Projects

Cityscapes in the United States are often viewed dichotomously in regards to natural environments. Preserved sites can be seen as an obstacle to urban development, and the concept of a functioning ecosystem within city limits is fictitious to many; we assume the two cannot coexist. Lynchburg, Virginia’s College Lake offers a unique case study for how urban ecosystems can not only subsist within cities but provide pivotal functions for them as well. With the potential for a dam-breaching storm event increasing in possibility with each passing year, concerns regarding the structural integrity of the College Lake dam in Lynchburg, Virginia …

Seabird Distribution And Oil & Gas Potential Along The Northern Sea Route, Russia: An Arctic Marine Conservation Case Study, Meghan Kelly

Sustainability and Social Justice

Seabirds are indicator species for the marine environment. Their populations are simultaneously affected by access to food resources and anthropogenic pressures including direct disturbance and habitat degradation associated with industrial development (Parsons et al. 2007). Therefore, using seabird distribution as a policy-relevant indicator for the Arctic marine environment supports an ecosystem based management approach aimed at protecting sensitive habitats from increased offshore oil and gas development.

This research identifies seabird habitat in the Russian Arctic utilizing in situ seabird observations from the Northern Sea Route to create a species distribution model. The spatial location of these areas will be compared …

Degrowth Lessons From Cuba, Claire S. Bayler

Sustainability and Social Justice

Cuba is the global leader in practicing agroecology, but agroecology is just one component of a larger climate-ready socio-economic system. Degrowth economics address the need to constrain our total global metabolism to within biophysical limits, while allowing opportunity and resources for "underdeveloped" countries to rebuild themselves under new terms. Degrowth recognizes the role of overdeveloped countries in surpassing the ecological limits of our planet at the cost of wellbeing for billions of dispossessed people within and between countries. Cuba's circumstances during and following the Special Period exemplify both sides of the degrowth scenario, as well as demonstrating policy and grassroots …

Applying Place-Based Social-Ecological Research To Address Water Scarcity: Insights For Future Research, Jodi Brandt

Human-Environment Systems Research Center Faculty Publications and Presentations

Globally, environmental and social change in water-scarce regions challenge the sustainability of social-ecological systems. WaterSES, a sponsored working group within the Program for Ecosystem Change and Society, explores and compares the social-ecological dynamics related to water scarcity across placed-based international research sites with contrasting local and regional water needs and governance, including research sites in Spain and Sweden in Europe, South Africa, China, and Alabama, Idaho, Oklahoma, and Texas in the USA. This paper aims to provide a commentary on insights into conducting future solutions-oriented research on water scarcity based on the understanding of the social-ecological dynamics of water scarce …

Winter Bat Activity In A Landscape Without Traditional Hibernacula, Amy M. Hammesfahr, Rene E. Ohms

United States National Park Service: Publications

Abstract

Prior to 2014, bat research at Devils Tower National Monument (DETO) focused on bats present during the summer months. Biologists at DETO assumed local bats were strictly summer residents due to the presumed lack of typical habitat features associated with bat hibernation, such as caves and mines. This lack of traditional hibernacula features at DETO discouraged staff and research cooperators from studying winter bat populations. Despite the earlier assumption that bats were unlikely to hibernate on the monument, DETO documented significant winter bat activity through passive winter acoustic monitoring. This study is the first study at DETO that documents …

This collaborative effort is part of a long-term monitoring program established to better …

Irrigation Practice Adoption: Causes And Consequences In The Arkansas Delta, Kerr James Adams

Graduate Theses and Dissertations

Concerns about groundwater depletion from conventional irrigation agriculture in the Arkansas Delta region have led to the promotion of more efficient irrigation practices. With Arkansas being the largest producer of rice, the 10th largest producer of soybeans and the 16th largest producer of corn in the United States, the irrigation demand of these crops has put pressure on producers to find ways to irrigate more efficiently. Not only are the alternative technologies supposed to reduce water use, it is also believed that their adoption can also yield economic benefits for the producer. Despite these assumed benefits, adoption of alternative technologies …

Disequilibrium Of Fire-Prone Forests Sets The Stage For A Rapid Decline In Conifer Dominance During The 21st Century, Josep M. Serra-Diaz, Charles Maxwell, Melissa S. Lucash, Robert M. Scheller, Danelle M. Laflower, Adam D. Miller, Alan J. Tepley, Howard E. Epstein, Kristina J. Anderson-Teixeira, Jonathan R. Thompson

Environmental Science and Management Faculty Publications and Presentations

As trees are long-lived organisms, the impacts of climate change on forest communities may not be apparent on the time scale of years to decades. While lagged responses to environmental change are common in forested systems, potential for abrupt transitions under climate change may occur in environments where alternative vegetation states are influenced by disturbances, such as fire. The Klamath mountains (northern California and southwest Oregon, USA) are currently dominated by carbon rich and hyper-diverse temperate conifer forests, but climate change could disrupt the mechanisms promoting forest stability– regeneration and fire tolerance— via shifts in the fire regime in conjunction …

Devonian Stromatoporoid Interactions At The Falls Of The Ohio State Park, Clarksville, Indiana, Morgan Sierra Hall

Undergraduate Theses

Stromatoporoids are calcitic sponges that occurred in the fossil record from the Early Ordovician to Late Devonian period. These sponges interacted with other organisms, especially rugose and tabulate corals. Some corals appear to benefit from the rigidity of stromatoporoids in response to turbulent waters. Stromatoporoids and many corals went extinct during the Frasnian-Famennian crisis when paleoenvironmental parameters were shifting. Studying the relationships between these taxa may provide insight to their vulnerability during the extinction.

This research was performed at the Falls of the Ohio in Clarksville, Indiana. Organisms in the Coral Zone were studied using transect sampling. Each fossil along …

This study considers the various factors that regulate nutrients supply in the Red Sea. Multi-sensor observation and reanalysis datasets are used to examine the relationships among dust deposition, sea surface temperature (SST), and wind speed, as they may contribute to anomalous phytoplankton blooms, through time-series and correlation analyses. A positive correlation was found at 0–3 months lag between chlorophyll-a (Chl-a) anomalies and dust anomalies over the Red Sea regions. Dust deposition process was further examined with dust aerosols’ vertical distribution using satellite lidar data. Conversely, a negative correlation was found at 0–3 months lag between SST anomalies …
