Influence Of Internal Variability On Population Exposure To Hydroclimatic Changes, Justin S. Mankin, Daniel Viviroli, Mesfin Mekonnen, Arjen Y. Hoekstra, Radley M. Horton, Jason E. Smerdon, Noah S. Diffenbaugh

Daugherty Water for Food Global Institute: Faculty Publications

Future freshwater supply, human water demand, and people’s exposure to water stress are subject to multiple sources of uncertainty, including unknown future pathways of fossil fuel and water consumption, and ‘irreducible’ uncertainty arising from internal climate system variability. Such internal variability can conceal forced hydroclimatic changes on multi-decadal timescales and near-continental spatial-scales. Using three projections of population growth, a large ensemble from a single Earth system model, and assuming stationary per capita water consumption, we quantify the likelihoods of future population exposure to increased hydroclimatic deficits, which we define as the average duration and magnitude by which evapotranspiration exceeds precipitation …

How Lessons From A Past Disaster Can Influence Resilience And Climate Adaptation In Broward County, Florida, Hannah Rose Torres

USF Tampa Graduate Theses and Dissertations

The first phase (Chapter 2), explored the concept of resilience to understand how it was defined in three South Florida communities. Content analyses of city and …

The Response Of High Elevation Wetlands To Past Climate Change, And Implications For The Future, Ian Arthur Slayton

Electronic Theses and Dissertations

As part of the ongoing investigation of mid-latitude fens in Colorado by University of Denver paleoenvironment researchers, research directed at examining the response of mid-latitude subalpine fens to past climatic events potentially analogous to modern anthropogenic climate change was undertaken. As part of this research, a 4.18 m sediment core was retrieved from Harbison Pond (2651 m elev) near Grand Lake, CO and a 3.12 m peat core was collected from Whiskey Fen (2792 m elev) in the Never Summer Range. Stratigraphic evidence indicates the kettle lake formed shortly after the Last Glacial Maximum, at least 16,201 cal yr BP …

Exploring Historical Coffee And Climate Relations In Southern Guatemala: An Integration Of Tree Ring Analysis And Remote Sensing Data, Diego Pons

Electronic Theses and Dissertations

This dissertation makes use of a physical geography perspective to examine the relationship between agriculture and climate in Guatemala using dendrochronology. I examined the potential of high-resolution climate proxy data from dendrochronology to help fill in the gaps of past climate information to better understand the natural and anthropogenic variability of precipitation which, in turn, can inform Guatemala’s agriculture sector. This research has demonstrated successful cross-dating and climate sensitivity of Abies guatemalensis in the Pacific slope of Guatemala. Based on this, I have produced a 124-year record of mean precipitation from June-July-August. The mean precipitation from June-July-August at this site …

The Role Of Natural Gas In The Clean Power Plan, Lincoln L. Davies, Victoria Lumen

Utah Law Faculty Scholarship

This article overviews the role that natural gas has played over time in the United States. It identifies and surveys five key historical roles that natural gas has served: (1) as an early competitor for lighting, (2) as a nuisance byproduct in oil production, (3) as a heating and appliance fuel, especially as pipeline technology improved, (4) as a catalyst for legal change during the energy crises, and (5) as an increasingly important fuel for electricity production. The article then examines the likely role of natural gas as way to address climate change in the United States, using the ideas …

Political Ecology Of Medicinal Plant Use In Rural Nepal: Globalization, Environmental Degradation, And Cultural Transformation, Emily Dovydaitis

Honors Undergraduate Theses

Prior to the advent of biomedicine, rural communities in Nepal relied on phytochemically active compounds in medicinal plants as their primary source of medicine; however, ethnobotanical practices have shifted over time due to economic, environmental, and sociocultural stimuli. Findings from 2016 fieldwork conducted in Dumrikharka, Nepal and Tutung, Nepal are compared to existing literature to describe the political ecology of medicinal plants in rural Nepal.

Anthropogenic climate change threatens individual plant species and ecosystem biodiversity. Globalized markets unabated by weak conservation programs place increasing demands on medicinal plants. As indigenous plants become overharvested and more difficult to access, Nepalis incorporate …

Collaborating For Coastal Resilience: Stakeholder Assessment And Perception Of Interdependence In Seabrook, Nh, Emily Bialowas

Master's Theses and Capstones

Like many coastal communities, the beach and dune ecosystems in Seabrook, New Hampshire are vulnerable to storm surge, sea-level rise, and extreme weather. Fostering coastal resilience in Seabrook requires local, regional, state, and federal stakeholders to collaborate on a broad range of issues. According to alternative dispute resolution (ADR) theory, stakeholders need to recognize their interdependence to be willing to collaborate. Interdependent stakeholders are aware their interests cannot be met by working alone and that their independent actions impact one another through complex social and ecological feedback loops. ADR practitioners often conduct a stakeholder assessment(SA) as a first step in …

An Analysis Of Long-Term Effects Of Climate Change And Socioeconomic Activities On Grassland Productivity Of Inner Mongolia, Siyu Fan

Master's Theses and Doctoral Dissertations

In recent years, researchers have recognized the complexity of the interactions between the ecological system and the economic development of human society. However, the complicated relationships overwhelm traditional statistical procedures and require an innovative approach to investigate their dynamics. We proposed this study to provide a unique perspective in analyzing the long-term causal relationships between the grassland productivity, climate change, and socioeconomic development of Inner Mongolia Autonomous Region (IMAR) of China. Our attempt began with acquiring remotely sensed satellite imagery, climatic variations, and aggregated annual reports of the socio-economy of the IMAR in vegetation growing seasons for 15 years. The …

Information Technology Approaches To Forest Management, Mary Snow, Richard Snow

Publications

The majority of the world’s forests occur where there is a dry season long enough to affect a seasonal change in the forest community. The seasonal forest may include evergreen, semi-deciduous, deciduous trees, or some combination of these. Local differences in soil or other site characteristics often determine which community persists. Since the seasonal forests exist where there is seasonal precipitation, the character of the forest is closely associated with the length of the rainy season. As the length of the rainy season decreases, the density of the canopy decreases. If the global climate system warms and prolonged drought gives …

Complexity Confers Stability: Climate Variability, Vegetation Response And Sand Transport On Longitudinal Sand Dunes In Australia’S Deserts, Paul P. Hesse, Matt W. Telfer, Will Farebrother

School of Geography, Earth and Environmental Sciences

Abstract The relationship between antecedent precipitation, vegetation cover and sand movement on sand dunes in the Simpson and Strzelecki Deserts was investigated by repeated (up to four) surveys of dune crest plots (≈25 × 25 m) over a drought cycle (2002–2012) in both winter (low wind) and spring (high wind). Vegetation varied dramatically between surveys on vegetated and active dune crests. Indices of sand movement had significant correlations with vegetation cover: the depth of loose sand has a strong inverse relationship with crust (cyanobacterial and/or physical) while the area covered by ripples has a strong inverse relationship with the areal …

Antioch University Dissertations & Theses

Around the world, municipalities are facing new challenges, not the least of which is climate change. This is especially true for rural communities that, for a variety of reasons, will be disproportionately affected by the climatic changes and accompanying policies or programs.

This dissertation, written in manuscript-style, integrates climate change and social-ecological scholarship to address the unique character of rural communities, to communicate the complexity of rural identity through the term "rural character"; and to empower rural communities to incorporate adaptation strategies into their daily municipal operations and planning.

Specifically, this dissertation seeks to answer the following questions: What is …

Assessing The Vulnerability Of Fishery Villages Influenced By Climate Change And Anthropogenic Activity In The Coastal Zone Of The Tamsui River, Sheng-Yuan Teng, Ming-An Lee, Jhen Hsu, Tzu-Ping Lin, Yu-Chen Lin, Yi Chang

Journal of Marine Science and Technology–Taiwan

Coastal zones located in populated and rapidly developing areas face high risks of natural and anthropogenic disasters. In this study, a framework was developed to determine the indicators of vulnerability to natural and anthropogenic disasters in Chuwei and Tamsui, two northern Taiwanese fishing villages in the coastal zone of the Tamsui River. The analytical hierarchy process (AHP) was used to determine the vulnerability indices of the locations, with experts evaluating the weights assigned to a range of criteria, namely hydrological data (such as sea surface temperature and sea level), stakeholder perceptions, and fishery data. These two villages have a considerably …

Biopolarity: Coral Scientists Between Hope And Despair, Irus Braverman

Journal Articles

Biopolarity draws on extensive interviews with dozens of coral scientists and on my observations of the international coral reef symposium in Hawaii on June 2016 to document the oscillation of coral scientists between hope and despair in their imaginations of coral futures. At one extreme of the oscillation are catastrophic predictions of the death of corals by the mid-21st century. In this despondent narrative, corals are getting fried and nothing short of an abrupt (and unlikely) shift in how humans use fossil fuels will save them. The pessimistic trajectory of this swing of the pendulum comes replete with daunting maps, …

Flood Realities, Perceptions, And The Depth Of Divisions On Climate, Lawrence C. Hamilton, Cameron P. Wake, Joel N. Hartter, Thomas G. Safford, Alli J. Puchlopek

Sociology

Research has led to broad agreement among scientists that anthropogenic climate change is happening now and likely to worsen. In contrast to scientific agreement, US public views remain deeply divided, largely along ideological lines. Science communication has been neutralised in some arenas by intense counter-messaging, but as adverse climate impacts become manifest they might intervene more persuasively in local perceptions. We look for evidence of this occurring with regard to realities and perceptions of flooding in the northeastern US state of New Hampshire. Although precipitation and flood damage have increased, with ample news coverage, most residents do not see a …

Future Decreases In Freezing Days Across North America, Michael A. Rawlins, Raymond S. Bradley, Henry F. Diaz, John S. Kimball, David A. Robinson

Numerical Terradynamic Simulation Group Publications

This study used air temperatures from a suite of regional climate models participating in the North American Climate Change Assessment Program (NARCCAP) together with two atmospheric reanalysis datasets to investigate changes in freezing days (defined as days with daily average temperature below freezing) likely to occur between 30-yr baseline (1971–2000) and midcentury (2041–70) periods across most of North America. Changes in NARCCAP ensemble mean winter temperature show a strong gradient with latitude, with warming of over 4°C near Hudson Bay. The decline in freezing days ranges from less than 10 days across north-central Canada to nearly 90 days in the …

The Impact Of A Large-Scale Climate Event On Antarctic Ecosystem Processes, Andrew G. Fountain, Grace Saba, Byron Adams, Peter Doran, William Fraser, Michael Gooseff, Maciej Obryk, John C. Priscu, Sharon Stammerjohn, Ross A. Virginia

Faculty Publications

© 2016 The Author(s) 2016. Extreme climate and weather events, such as a drought, hurricanes, or ice storms, can strongly imprint ecosystem processing and may alter ecosystem structure. Ecosystems in extreme environments are particularly vulnerable because of their adaptation to severe limitations in energy, water, or nutrients. The vulnerability can be expressed as a relatively long-lasting ecosystem response to a small or brief change in environmental conditions. Such an event occurred in Antarctica and affected two vastly different ecosystems: a marine-dominated coastal system and a terrestrial polar desert. Both sites experienced winds that warmed air temperatures above the 0°C threshold, …

Assessing Climate Change Impacts On Water Resources In The Songhua River Basin, Fengping Li, Guangxin Zhang, Y. Jun Xu

Faculty Publications

The Songhua River Basin (SRB) in Northeast China is one of the areas most sensitive to global climate change because of its high-latitude location. In this study, we conducted a modeling assessment on the potential change of water resources in this region for the coming three decades using the Soil and Water Assessment Tool (SWAT). First, we calibrated and validated the model with historical streamflow records in this basin. Then, we applied the calibrated model for the period from 2020 to 2049 with the projected and downscaled climatic data under two emission scenarios (RCP 4.5 and RCP 8.5). The study …

The International Whaling Commission—Beyond Whaling, Andrew J. Wright, Mark P. Simmonds, Barbara Galletti Vernazzani

Wildlife Population Management Collection

Since its establishment in 1946 as the international body intended to manage whaling, the International Whaling Commission (IWC) has expanded its areas of interest to ensure the wider conservation of whales. Several key conservation topics have been taken forward under its auspices including climate change, chemical and noise pollution, marine debris and whale watching. Work on each of these topics at the IWC has grown substantially since the 1990s and remains ongoing. Important developments were the establishment of the Standing Working Group on Environmental Concerns in 1996 and the IWC’s Conservation Committee in 2003. Trying to address this diverse set …

Coastal Louisiana: Adaptive Capacity In The Face Of Climate Change, Tara Lambeth

LSU New Orleans Theses and Dissertations

Extreme weather events can result in natural disasters, and climate change can cause these weather events to occur more often and with more intensity. Because of social and physical vulnerabilities, climate change and extreme weather often affect coastal communities. As climate change continues to be a factor for many coastal communities, and environmental hazards and vulnerability continue to increase, the need for adaptation may become a reality for many communities. However, very few studies have been done on the effect climate change and mitigation measures implemented in response to climate change have on a community’s adaptive capacity.

This single instrumental …

Wildfire, Climate, And Perceptions In Northeast Oregon, Lawrence C. Hamilton, Joel N. Hartter, Barry D. Keim, Angela E. Boag, Michael W. Palace, Forrest R. Stevens, Mark J. Ducey

Sociology

Wildfire poses a rising threat in the western USA, fueled by synergies between historical fire suppression, changing land use, insects and disease, and shifts toward a drier, warmer climate. The rugged landscapes of northeast Oregon, with their historically forest- and resource-based economies, have been one of the areas affected. A 2011 survey found area residents highly concerned about fire and insect threats, but not about climate change. In 2014 we conducted a second survey that, to explore this apparent disconnect, included questions about past and future summertime (fire season) temperatures. Although regional temperatures have warmed in recent decades at twice …

Linking In-Situ Data With Remote Sensing To Analyze Tropical Glacier Stability And Retreat In The Cordillera Blanca, Peru, Chandler H. Santos

Masters Theses & Specialist Projects

Glaciers are a major source of freshwater around the world, but they are melting at an increased rate due to atmospheric warming resulting from anthropogenic climate change. In addition to temperature increases, light-absorbing particulates on glaciers also are contributing to glacial melt. This research examines how black carbon, released into the air through partial combustion of biofuels, is affecting the surface albedo of glaciers. I also delineate possible sources of black carbon in the Cordillera Blanca region of Peru. Ground data were collected each year from 2011 to 2013 during the local dry season. Effective black carbon (eBC) values were …

Agenda: Coping With Water Scarcity In River Basins Worldwide: Lessons Learned From Shared Experiences, University Of Colorado Boulder. Getches-Wilkinson Center For Natural Resources, Energy, And The Environment

Coping with Water Scarcity in River Basins Worldwide: Lessons Learned from Shared Experiences (Martz Summer Conference, June 9-10)

Water scarcity is increasingly dominating headlines throughout the world. In the southwestern USA, the looming water shortages on the Colorado River system and the unprecedented drought in California are garnering the greatest attention. Similar stories of scarcity and crisis can be found across the globe, suggesting an opportunity for sharing lessons and innovations. For example, the Colorado River and Australia's Murray-Darling Basin likely can share many lessons, as both systems were over-allocated, feature multiple jurisdictions, face similar climatic risks and drought stresses, and struggle to balance human demands with environmental needs. In this conference we cast our net broadly, exploring …

Extraterritoriality, Externalities, And Cross-Border Trade: Some Lessons From The United States, The European Union, And The World Trade Organization, Max S. Jansson

Pace Environmental Law Review

In this article, process and production method (PPM) rules are analyzed under three jurisdictions: the United States, the European Union (EU), and the World Trade Organization (WTO. The approach is justified by the fact that their rules on interstate trade reflect very similar basic objectives related to anti-protectionism. Moreover, the regimes, to a large extent, share the same structure of rules on prohibition balanced with rules on justification. All in all, the regimes reveal similar syntax. The comparability of the U.S. Dormant Commerce Clause Doctrine with both WTO law and EU free movement law has been highlighted already in previous …
