Reevaluating Wilderness Classification And Management In The Face Of Climate Change: A Reconsideration Of Values And Ecology, Katherine Fiedler

Pace Environmental Law Review

In recognizing that the very nature of wilderness is a human construct, the values sought to be preserved can and should be reevaluated, considering the importance of wilderness in light of climate change and global ecosystem resilience, as well as how wilderness is designated and managed. Furthermore, the values that wilderness provides us will dramatically increase as climate change proceeds. Section II of this article describes the basics of wilderness protection, including the evolution of our relationship with wilderness, the history of the Wilderness Act, and what, how, and why wilderness is protected under the Act. Section III explores how …

The Water-Energy-Climate Nexus Under International Law: A Central Asian Perspective, Anatole Boute

Michigan Journal of Environmental & Administrative Law

Water, energy, and climate change are intrinsically related to each other but are nonetheless subject to different international legal regimes. The fragmented nature of water, energy, and climate governance represents a challenge for the sustainable management of resources in the energy and water landscape of the 21st century. Regulatory choices in one field can potentially undermine the policy objectives pursued in the other fields. Promoting conventional and unconventional energy production for energy security purposes increases pressure on the availability of fresh water resources and contributes to climate change. Climate change exacerbates the scarcity of water resources, which leads to increasing …

Investigating The Influences Of Climate On The High Elevation Snowpack Hydrology In The Upper Colorado Region., Claire-Louise Bode

Electronic Theses and Dissertations

A change in climate in the western United States has already affected and will continue to affect the onset of snow melt in many parts of the country. The effect of climate change on snow water equivalent, snowmelt runoff and total streamflow with respect to their elevation distribution is examined across the Colorado Headwaters Basin. This is a high altitude location within the Upper Colorado Basin region. The total streamflow of this region has a significant contribution from the spring season snow melt. An increase in air temperature in the Colorado Headwaters Basin over a few years will change the …

Dynamic Simulation And Numerical Analysis Of Hurricane Storm Surge Under Sea Level Rise With Geomorphologic Changes Along The Northern Gulf Of Mexico, Matthew V. Bilskie, S. C. Hagen, Karim Alizad, S. C. Medeiros, D. L. Passeri, H. F. Needham, A. Cox

Faculty Publications

This work outlines a dynamic modeling framework to examine the effects of global climate change, and sea level rise (SLR) in particular, on tropical cyclone-driven storm surge inundation. The methodology, applied across the northern Gulf of Mexico, adapts a present day large-domain, high resolution, tide, wind-wave, and hurricane storm surge model to characterize the potential outlook of the coastal landscape under four SLR scenarios for the year 2100. The modifications include shoreline and barrier island morphology, marsh migration, and land use land cover change. Hydrodynamics of 10 historic hurricanes were simulated through each of the five model configurations (present day …

Cultural And Economic Factors That Influence Brazilian Public Opinion On Climate Change, Jenna Williams

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Climate change is a commons problem of global proportions. The effects of climate change threaten not only the natural world, but also the human systems that we have established (IPCC 2014, 4). The devastating effects of climate change will not be confined to those regions of the world that have contributed the most to this problem. Already, every continent and ocean has been touched by climate change (IPCC 2014, 4).

A Spatiotemporal Mountain Pine Beetle Outbreak Model Predicting Severity, Cycle Period, And Invasion Speed, Jacob P. Duncan

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The mountain pine beetle (MPB, Dendroctonus ponderosae), a tree-killing bark beetle, has historically been part of the normal disturbance regime in lodgepole pine (Pinus contorta) forests. In recent years, warm winters and summers have allowed MPB populations to achieve synchronous emergence and successful attacks, resulting in widespread population outbreaks and resultant tree mortality across western North America. We develop an age-structured forest demographic model that incorporates temperature-dependent MPB infestations: the Susceptible-Infested-Juvenile (SIJ) model. Stability of equilibria is analyzed as a function of population growth rates, and indicates the existence of periodic outbreaks that intensify as growth rates …

Mapping Temperate Vegetation Climate Adaptation Variability Using Normalized Land Surface Phenology, Liang Liang, Mark D. Schwartz, Xiaoyang Zhang

GSCE Faculty Publications

Climate influences geographic differences of vegetation phenology through both contemporary and historical variability. The latter effect is embodied in vegetation heterogeneity underlain by spatially varied genotype and species compositions tied to climatic adaptation. Such long-term climatic effects are difficult to map and therefore often neglected in evaluating spatially explicit phenological responses to climate change. In this study we demonstrate a way to indirectly infer the portion of land surface phenology variation that is potentially contributed by underlying genotypic differences across space. The method undertaken normalized remotely sensed vegetation start-of-season (or greenup onset) with a cloned plants-based phenological model. As the …

This assessment evaluates the effects of future climate change on a select set of ecological systems and ecosystem services in Alaska’s Kenai Peninsula and Chugach National Forest regions. The focus of the assessment was established during a multi-agency/organization workshop that established the goal to conduct a rigorous evaluation of a limited range of topics rather than produce a broad overview. The report explores the potential consequences of climate change for: (a) snowpack, glaciers, and winter recreation; (b) coastal landscapes and associated environments, (c) vegetation, (d) salmon, and (e) a select set of wildlife species. During the next half century, directional …

How Landscape Ecology Informs Global Land-Change Science And Policy, Buma, Audrey Mayer, Amelie Davis, Sara Gagne, E. Louise Loudermilk, Robert Scheller, Fiona Schmiegelow, Yolanda Wiersma, Janet Franklin

Faculty, Staff, and Students

Landscape ecology is a discipline that explicitly considers the influence of time and space on the environmental patterns we observe and the processes that create them. Although many of the topics studied in landscape ecology have public policy implications, three are of particular concern: climate change; land use–land cover change (LULCC); and a particular type of LULCC, urbanization. These processes are interrelated, because LULCC is driven by both human activities (e.g., agricultural expansion and urban sprawl) and climate change (e.g., desertification). Climate change, in turn, will affect the way humans use landscapes. Interactions among these drivers of ecosystem change can …

Taking The Oceanfront Lot, Josh Eagle

Faculty Publications

Oceanfront landowners and states share a property boundary located between the wet and dry parts of the shore. This legal coastline is different from an ordinary land boundary. First, on sandy beaches, the line is constantly in flux, and it cannot be marked except momentarily. Without the help of a surveyor and a court, neither the landowner nor a citizen walking down the beach has the ability to know exactly where the line lies. This uncertainty means that, as a practical matter, ownership of some part of the beach is effectively shared. Second, the common law establishes that the owner …

Long Live The King? A Gis Analysis Of Climate Change’S Impact On The Future Wintering Range And Economy Of The Monarch Butterfly (Danaus Plexippus) In Mexico, Megan E. Zagorski

Student Publications

The annual migration of the monarch butterfly (Danaus plexippus) is a natural phenomenon widely integrated into the popular and social imagination of North America. However, this migratory population has recently declined. I investigated the threat of climate change on the future distribution of suitable monarch habitat, using ArcGIS to create a model of current and future monarch habitat. I also analyzed municipal data for 5 communities in Mexico State in an examination of the social aspects of the Monarch Butterfly Biosphere Reserve [MBBR]. According to my model, an estimated 38.6% to 69.8% of current monarch habitat may be lost within …

Concerns Of Water Scarcity And Water Quality Among Two Andean Communities In Peru, Kelsey Anne Anderson

USF Tampa Graduate Theses and Dissertations

This thesis sought to explore the perceptions and experiences of Andean women regarding water quality, water scarcity, and health among two communities in Carhuaz province of Ancash, Peru. Household surveys (n=25), semi-structured interviews (n=10), unstructured interviews (n=2), and participant observation were conducted with local women to investigate their concerns and perceptions of water and health. An additional two unstructured interviews were conducted with a local water authority and doctor in order gain another perspective on the issues of water security and health.

The pressure of a changing climate and of a problematic water governance system in Andean Peru create an …

A Tale Of Three Markets: Comparing The Renewable Energy Experiences Of California, Texas, And Germany, Felix Mormann, Dan Reicher, Victor Hanna

Faculty Scholarship

The Obama administration has repeatedly identified the large-scale build-out of clean, renewable energy infrastructure as a key priority of the United States. The President’s calls for a cleaner energy economy are often accompanied by references to other industrialized countries such as Germany, hailed by many as a leader in renewable energy deployment. Indeed, the share of renewables in Germany’s electricity generation mix is twice that of the United States, and the ambitious “Energiewende” commits the country to meeting 80% of its electricity needs with renewables by 2050. While some praise the German renewables experience as successful proof of concept, others …

Alien Invasion! An Ocean Picture Coming To A Sea Near You: An Analysis Of International Frameworks For Aquatic Invasive Species Control, Kelly Cox

University of Miami Inter-American Law Review

Aquatic invasive species are marine, estuarine, or freshwater organisms that adversely impact ecosystems they are not native to. Such impacts include long-lasting or permanent damage to habitats, ecosystem balance, and biodiversity. These impacts have a cascading effect on local economies dependent on these natural resources by impeding recreational and commercial activities. Moreover, aquatic invasive species control and management is both complex and challenging due to the lack of physical barriers in aquatic environments to abate or contain the spread of these nuisance species. The Wider Caribbean Region has been notably impacted by the introduction of the non-native lionfish (Pterois volitans) …

The Grass Is Not Always Greener: Congressional Dysfunction, Executive Action, And Climate Change In Comparative Perspective, Hari M. Osofsky, Jacqueline Peel

Chicago-Kent Law Review

Partisan climate change politics, paired with a legislative branch that is often deeply divided between two parties, has led to congressional gridlock in the United States. Numerous efforts at passing comprehensive climate change legislation have failed, and little prospect exists for such legislation in the foreseeable future. As a result, executive action under existing federal environmental statutes—often in interaction with litigation—has become the primary mechanism for national-level regulation of greenhouse gas emissions from motor vehicles and power plants.

Although many observers critique this state of affairs and wish for a legislature more able to act, this essay argues that more …

Renewable Energy Consumption: Initiatives In Colorado And Washington, Robin K. Doroff

Journal of Environmental and Resource Economics at Colby

This paper examines the use of policy mechanisms to increase renewable energy consumption within the United States. In order to effectively measure the change of renewable energy consumption, I analyze two initiatives that promote energy consumption from renewable sources and overall increases in energy conservation. Colorado and Washington had approved initiatives in the years 2004 and 2006, respectively. Although the results are not entirely statistically significant, I find that the initiatives lead to increases in total renewable energy consumption and decreases in total energy use.

Zoning Neighborhoods For Resilience: Drivers, Tools And Impacts, Shelby D. Green

Elisabeth Haub School of Law Faculty Publications

A new urban design is needed, one that if not climate-determinist, is climate-cognizant. The built environment should be structured and the natural environment must be managed and protected in a way that regards climate forces that if left unchecked will sap the energy, the very existence of the city.7 A new urban design must begin with a statement of clear ends to be achieved, be based upon authoritative scientific, legal and social principles and must be implemented with an understanding of the costs--monetary and socio-political, that are demonstrably justified in the light of the alternatives. The extravagant and pretentious historical …

Forgetting Nature: The Importance Of Including Environmental Flows In International Water Agreements, Amy Hardberger

Faculty Articles

From the moment States created political boundaries to define their territory, they have shared water. There are 263 transboundary lake and river basins worldwide and 300 known transboundary aquifer systems. Whenever sharing is present, the opportunity for conflict is too. Climate change and increasing population are only two factors that may lead to increasing conflict if attention is not given to these situations. Thankfully, sharing water also creates an opportunity for cooperation. Throughout the world, there are increasing examples of conflict and cooperation regarding shared water resources. International water agreements can promote regional peace and security and encourage economic growth. …

Pre-Service Teachers And Climate Change: A Stalemate?, Helen J. Boon

Australian Journal of Teacher Education

Findings from the second phase of a study of pre-service teachers’ attitudes to environmental education and knowledge of climate change are reported in this paper. A sample of 87 pre-service teachers participated in a survey study in the last year of their Bachelor of Education degree to examine developments to their attitudes to environmental education and their knowledge of climate change as a result of training. Results showed their attitudes towards environmental education were consistently favourable, but their climate change science knowledge had not changed as a result of their participation in their degree. Data on preservice teachers’ sources of …

Climate Change On The Therapist's Couch : How Mental Health Clinicians Receive And Respond To Indirect Psychological Impacts Of Climate Change In The Therapeutic Setting, Elizabeth B. Seaman

Theses, Dissertations, and Projects

The scientific community has reached near consensus that climate change (also known as anthropogenic global warming) poses a significant and potentially dire threat to the ecosystems upon which we, as humans and as a society, rest. While climate change is most often discussed in terms of its effect on the natural environmental, its psychological impacts are also expected to be immense and varied and include indirect distress related to the threat that climate change poses. The purpose of this study was to explore how this kind of indirect distress gets talked about in the therapeutic setting. Using a mixed methods …

Understanding The Structure And Functioning Of Polar Pelagic Ecosystems To Predict The Impacts Of Change, E. E. Murphy, R. D. Cavanagh, K. F. Drinkwater, S. M. Grant, J. J. Heymans, E. E. Hofmann, G. L. Hunt Jr., N. M. Johnston

CCPO Publications

The determinants of the structure, functioning and resilience of pelagic ecosystems across most of the polar regions are not well known. Improved understanding is essential for assessing the value of biodiversity and predicting the effects of change (including in biodiversity) on these ecosystems and the services they maintain. Here we focus on the trophic interactions that underpin ecosystem structure, developing comparative analyses of how polar pelagic food webs vary in relation to the environment. We highlight that there is not a singular, generic Arctic or Antarctic pelagic food web, and, although there are characteristic pathways of energy flow dominated by …

The Sea Is Rising… But Not Onto The Policy Agenda: A Multiple Streams Approach To Understanding Sea Level Rise Policies, Juita-Elena (Wie) Yusuf, Katharine Neill, Burton St. John Iii, Ivan K. Ash, Kaitrin Mahar

School of Public Service Faculty Publications

There has been little policy effort to address sea level rise in coastal states in the US. It is important to examine, at the state level, how the multitude of different (and changing) actors with different preferences and perspectives contribute to such inertia. This study examines state-level legislative inaction with regards to sea level rise. Using Kingdon's multiple streams framework, we draw a picture of the policy landscape in Virginia as one where the problem of sea level rise is perceived as a low priority, with little consensus on achievable policy solutions, and is politically controversial. We find that policy …

Building Resiliency In Response To Sea Level Rise And Recurrent Flooding: Comprehensive Planning In Hampton Roads, Joshua G. Behr, Rafael Diaz, Molly Mitchell

VMASC Publications

[Introduction]

Over the past few decades, the Hampton Roads region, with its extensive coastline, has been experiencing more frequent flooding from surges and precipitation caused by tropical storms, nor’easters and heavy thunderstorms (Figure 1). Recurrent flooding is “flooding that occurs repeatedly in the same area over time due to precipitation events, high tides or storm surge.”¹ The recurrence of tidal/surge flooding in Hampton Roads has increased from 1.7 days of “nuisance” flooding per year in 1960 to 7.3 days per year in 2014.² Although there is no definitive region-wide data to document the increases in precipitation-induced flooding, there …

Is The Relationship Between Mast-Seeding And Weather In Oaks Related To Their Life-History Or Phylogeny?, Walter D.

Pesendorfer

School of Biological Sciences: Faculty Publications

Although the functional basis of variable and synchronous seed production (masting behavior) has been extensively investigated, only recently has attention been focused on the proximate mechanisms driving this phenomenon. We analyzed the relationship between weather and acorn production in 15 species of oaks (genus Quercus) from three geographic regions on two continents, with the goals of determining the extent to which similar sets of weather factors affect masting behavior across species and to explore the ecological basis for the similarities detected. Lag-1 temporal autocorrelations were predominantly negative, supporting the hypothesis that stored resources play a role in masting behavior …
