Plant Community Composition And Structure Monitoring For Agate Fossil Beds National Monument, 2013 Annual Report, Isabel W. Ashton, Michael Prowatzke

United States National Park Service: Publications

Introduction

During the last century, much of the prairie within the Northern Great Plains has been plowed for cropland, planted with non-natives to maximize livestock production, or otherwise developed, making it one of the most threatened ecosystems in the United States. Within Nebraska, greater than 77% of the area of native mixed-grass prairie has been lost since European settlement (Samson and Knopf 1994). The National Park Service (NPS) plays an important role in preserving and restoring some of the last pieces of intact prairies within its boundaries. The stewardship goal of the NPS is to “preserve ecological integrity and cultural …

Folk Food Webs And The Role Of Praxis In Substantive Ecological Knowledge, Yancey Orr, Brian Hallmark

Environmental Science and Policy: Faculty Publications

In the second half of the 20th century, investigations of indigenous environmental knowledge have been the subject of broader anthropological debates over how knowledge and experience are formed. Many such approaches have focused on environmental nomenclature and taxonomy, or what Roy Ellen has called "formal lexical knowledge" (1999). Such knowledge is readily available to an ethnographer and also more easily transmitted through language between subjects. These characteristics of formal lexical knowledge have led to considerable attention given to differences in environmental knowledge between cultures and have possibly resulted in the inflation of the efficacy of language in forming knowledge. However, …

A Discussion Of The Impact Of Political And Economic Forces On Equitable Access To Potable Water In Ecuador And Recommendations For Improvement Through Better Watershed Management, Eliza States

Pitzer Senior Theses

This thesis will address the impact of political and economic forces on the equitable access to fresh water in Ecuador. Demographic factors such as the rural-to-urban migration and the political and economic forces have strongly influenced the debate over the privatization of the provision of potable water and sanitation services. Within the context of Ecuador, two different approaches by the largest cities, Quito and Guayaquil, are analyzed; in Guayaquil, the services were privatized, while in Quito, the public utility was corporatized, remaining under public control. It concludes arguing that in the face of political instability and a lack of regulatory …

Renewable Energy, Mary Finley-Brook

Geography and the Environment Faculty Publications

Renewable energy installations are expanding around the globe. Although there is excellent potential for achieving sustainability with multiple types of renewable energy, no energy source is a panacea. There are place-specific costs and benefits from every energy type, and the scale of production influences impacts. Industrial-scale renewable energy sources usually merge into existing energy grids and may often be connected to broader economic and political initiatives. Such as regional integration, development of new growth poles to stimulate economic expansion in areas without infrastructure, job creation, or trade expansion. With the exception of desert solar projects or initiatives in remote areas, …

Assessing Resilience In Stressed Watersheds, Kristine T. Nemec, Joana Chan, Christina Hoffman, Trisha L. Spanbauer, Joseph A. Hamm, Craig R. Allen, Trevor Hefley, Donald Pan, Prabhakar Shrestha

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Although several frameworks for assessing the resilience of social-ecological systems (SESs) have been developed, some practitioners may not have sufficient time and information to conduct extensive resilience assessments. We have presented a simplified approach to resilience assessment that reviews the scientific, historical, and social literature to rate the resilience of an SES with respect to nine resilience properties: ecological variability, diversity, modularity, acknowledgement of slow variables, tight feedbacks, social capital, innovation, overlap in governance, and ecosystem services. We evaluated the effects of two large-scale projects, the construction of a major dam and the implementation of an ecosystem recovery program, on …

Modeling Effective Shade To Prioritize Riparian Restoration Efforts In The Johnson Creek Watershed, Or, Brittany Sahatjian

Environmental Science and Management Professional Master's Project Reports

The influence of stream temperature on the survival and reproductive success of anadromous salmonid populations has become an increasingly concerning issue in the Pacific Northwest. Enhancing the height, density and extent of riparian vegetation is widely accepted as one of the most effective strategies for reducing stream temperatures, while also providing numerous ancillary benefits. Effective shade is defined as the percentage of direct beam solar radiation attenuated and scattered by riparian vegetation before reaching the stream surface and is a commonly used criterion for choosing where to restore riparian vegetation. This project aims to prioritize sites for riparian restoration through …

Mangroves Facing Climate Change: Landward Migration Potential In Response To Projected Scenarios Of Sea Level Rise, D. Di Nitto, G. Neukermans, N. Koedam, H. Defever, F. Pattyn, J. G. Kairo, F. Dahdouh-Guebas

East Africa

Mangrove forests prominently occupy an intertidal boundary position where the effects of sea level rise will be fast and well visible. This study in East Africa (Gazi Bay, Kenya) addresses the question of whether mangroves can be resilient to a rise in sea level by focusing on their potential to migrate towards landward areas. The combinatory analysis between remote sensing, DGPS-based ground truth and digital terrain models (DTM) unveils how real vegetation assemblages can shift under different projected (minimum (+9 cm), relative (+20 cm), average (+48 cm) and maximum (+88 cm)) scenarios of sea level rise (SLR). Under SLR scenarios …

Assessing Possible Cruise Ship Impacts On Huna Tlingit Ethnographic Resources In Glacier Bay, Douglas Deur, Thomas Thornton

Anthropology Faculty Publications and Presentations

This report provides a thematic summary of an ethnographic study addressing the effects of cruise ships within Glacier Bay proper on the people known as the Huna Tlingit. Occupying the heart of Glacier Bay National Park and Preserve, Glacier Bay proper is considered to be the core homeland of Huna Tlingit. The Huna occupied the Bay prior to its most recent glaciation and, though they now live nearby in Hoonah and other communities, they have continued to use, occupy, and value the lands and waters within the Bay since the glaciers began to retreat over two centuries ago. Simultaneously, since …

Let's Not Eat Alone: A Search For Food Security Justice, Emma Shorr

Pitzer Senior Theses

The food justice movement has taken off in recent years. Despite its call for justice in the food system, it has been critiqued as being inaccessible to people who need food the most. The food system marginalizes women, minorities, and low-income people, making these groups the most at risk for food insecurity. Solutions to food insecurity come from both government and non-governmental avenues. This thesis calls for a merger of solutions to food insecurity and food justice in food security justice, and assesses the ability of solutions to food insecurity to confront issues of injustice. Community-based solutions currently have the …

“It’S Like We Are Free”: An Analysis Of Soccer-Based Programming In A California Prison, Lillian S. Barrett-O'Keefe

Pitzer Senior Theses

The concept of space goes well beyond just buildings and infrastructure; it can represent feelings of attachment and belonging, it can interact with us and generate meaning. The built environment is not just the “backdrop” of our lives, but rather it plays a major role in them. In the state of California prisons have become a prominent element of our communal landscape, now housing 2.4 million Americans today. This paper explores prisons as a rich site of analysis in terms of how our built environment affects our daily lives. In order to delve into this analysis, I will explore sport-based …

Missing Voices, Hidden Fields: The Gendered Struggles Of Female Farmworkers, Keiko A. Budech

Pitzer Senior Theses

Known for its fertile soil and ideal climate, California has been one of the most agriculturally productive areas in the world. Often left out of this picture are the farmworkers who make it possible. Within this farmworker community, females are a sub-class that has been even more marginalized. This thesis investigates the gendered aspects of fieldwork and exposes female leadership working towards changing these specific struggles, such as sexual harassment in the fields, domestic abuse, pesticide exposure, and the perpetuation of submissive gender roles in the household and workplace. An in-depth case study of Lideres Campesinas, a community- based grassroots …

The experiences of current users are presented describing how they have incorporated the BA curriculum into their courses, as well as how BA affected teaching and learning. The experiences demonstrate that BA can be used in whole or in part, is …

Natural Phenomena As Potential Influence On Social And Political Behavior: The Earth’S Magnetic Field, Jackie R. East

Theses and Dissertations--Political Science

Researchers use natural phenomena in a number of disciplines to help explain human behavioral outcomes. Research regarding the potential effects of magnetic fields on animal and human behavior indicates that fields could influence outcomes of interest to social scientists. Tests so far have been limited in scope. This work is a preliminary evaluation of whether the earth’s magnetic field influences human behavior it examines the baseline relationship exhibited between geomagnetic readings and a host of social and political outcomes. The emphasis on breadth of topical coverage in these statistical trials, rather than on depth of development for any one model, …

Monitoring The Influence Of Acid Deposition On Soil And Implications To Forest Health In The Daniel Boone National Forest, Tyler M. Sanderson

Theses and Dissertations--Forestry and Natural Resources

Combustion of fossil fuels has contributed to many environmental problems including acid deposition. The Clean Air Act (CAA) was created to reduce ecological problems by cutting emissions of sulfur and nitrogen. Reduced emissions and rainfall concentrations of acidic ions have been observed since the enactment of the CAA, but soils continue to receive some acid inputs. Soils sensitive to acid deposition have been found to have low pH, a loss of base cations and a shift in the mineral phase controlling the activity of Al³⁺ and/or SO₄^2-. If inputs continue, soil may be depleted of base …

Reconstruction Of The Hirnantian (Late Ordovician) Palaeotopography In The Upper Yangtze Region, Linna Zhang, Junxuan Fan, Qing Chen, Shuang-Ye Wu

Department of Earth, Environment and Sustainability Faculty Publications

Reconstruction of the Hirnantian (Late Ordovician) palaeotopography in South China is important for understanding the distribution pattern of the Hirnantian marine depositional environment. In this study, we reconstructed the Hirnantian palaeotopography in the Upper Yangtze region based on the rankings of the palaeo-water depths, which were inferred according to the lithofacies and biofacies characteristics of the sections. Data from 374 Hirnantian sections were collected and standardized through the online Geobiodiversity Database. The Ordinary Kriging interpolation method in the ArcGIS software was applied to create the continuous surface of the palaeo-water depths, i.e. the Hirnantian palaeotopography. Meanwhile, the line transect analysis …

Preliminary Multifactorial Analysis Of Parkinson's Disease, Max James Miller

Conservation Without Nature: The Trouble With In Situ Versus Ex Situ Conservation, Irus Braverman

Journal Articles

Although understudied in academia and mostly unheard of by the general public, the in situ/ex situ dichotomy has shaped — and still very much shapes — the development of the nature conservation movement and its institutional alliances in the last few decades. Latin for “in” and “out” of place, the in/ex situ dichotomy often stands for the seemingly less scientific dichotomy between wild nature and captivity. Drawing on ethnographic engagements with zoo professionals and wildlife managers, this article explores the evolution of the in situ/ex situ dyad in nature conservation, which traverses the worlds of dead and live matter, artificilia …

Comeback Of Community-Based Forest Management: The Need To Revamp Strategies To Promote Decentralized Environmental Governance In India And Brazil, Naysa Ahuja

Florida A & M University Law Review

The governance of forests and their resources has always been a contentious issue. It has created a divide between developing and developed countries, as well as within them. With the increasing recognition of forests as valuable commodities in the global market, the management of forests in developing countries is becoming a matter of constant concern for ecologists, economists, and politicians.

Part I of this article provides an overview of the Participatory Forest Management (PFM) approach in the international context. Part II and III examine environmental governance in the forest sector of two rapidly emerging economies of the world, India and …

Application Of Ce-Qual-W2 On Tigris River In Iraq, Muhanned Al-Murib

Civil and Environmental Engineering Master's Project Reports

The Tigris River is the eastern member of the two great rivers in Iraq. Two big rivers pass through Iraq, Mesopotamia. Tigris and Euphrates Rivers with their tributaries form a major river system in the Middle East. Four riparian countries, Turkey, Syria, Iran, and Iraq, share the Tigris River basin area and Iraq has the majority of this basin area. The total length of the Tigris is 1850 km from which 1418 km is within Iraq. A study area of 880 km from Mosul dam to Kut barrage is modeled using a water quality CE-QUAL-W2 model. CE-QUAL-W2 is a two-dimensional …

A Comparison Of Capacity For Resilience Among Coastal Communities In The Northeast U.S. And The Northern Gulf Of Mexico Region, Emily Gootee

LSU Master's Theses

Coastal communities face many threats from their surrounding environment, including floods and severe storms. These threats are exacerbated by climate change and sea level rise, which may cause increased frequency and severity of these events. Despite these hazards, population density along the coasts continues to rise. These areas of dense population and infrastructure are highly vulnerable to extreme weather events. Hurricane Sandy of 2012 was a powerful demonstration of the impact that severe storms can have on coastal populations. In the face of this reality, coastal communities must adapt and become more resilient to environmental changes. In order to assess …

The Adoption Of State Wetland Policies: How Do Wetlands Fit Within The Theoretical Framework Of Environmental Policy Determinants?, Rachel Bogart Krech

LSU Master's Theses

Wetlands are an extremely important natural resource in the United States. They offer storm surge protection, sediment stabilization, groundwater recharging, carbon sequestration, and habitat for many species. Despite their values, wetlands have a long history of being misunderstood. It was not until the mid-1970s that scientific understanding helped transform policy from that of rapid conversion to that of conservation. By this time, the lower 48 states had already lost 53 percent of its total wetlands. The nature of wetlands and federal limitations make the management of this natural resource a primarily state-based responsibility. However, the way that states construct their …

Sampling For Effective Ex Situ Plant Conservation, Edward O. Guerrant Jr., Kayri Havens, Pati Vitt

Environmental Science and Management Faculty Publications and Presentations

Sampling a whole flora or any significant subset for ex situ conservation purposes is a complex, long-term proposition. Thus, it is important to consider what constitutes an adequate sample not only for all taxa as a whole but also for each taxon individually as well as how to strategically schedule collection over time. There are five basic sampling questions: from which species to collect, from how many and which populations, from how many and which individuals, how many and what kind of propagules to collect, and, finally, at what point is the desired sample size too great for a population …

Improving The Representation Of Roots In Terrestrial Models, Erica A.H. Smithwick, Melissa S. Lucash, M. Luke Mccormack, Gajan Sivandran

Environmental Science and Management Faculty Publications and Presentations

Root biomass, root production and lifespan, and root-mycorrhizal interactions govern soil carbon fluxes and resource uptake and are critical components of terrestrial models. However, limitations in data and confusions over terminology, together with a strong dependence on a small set of conceptual frameworks, have limited the exploration of root function in terrestrial models. We review the key root processes of interest to both field ecologists and modelers including root classification, production, turnover, biomass, resource uptake, and depth distribution to ask (1) what are contemporary approaches for modeling roots in terrestrial models? and (2) can these approaches be improved via recent …

An African-Centered Approach To Land Education, Salvotore Engel-Dimauro, Karanja Keita Carroll

Publications and Research

Approaches to environmental education which are engaging with place and critical pedagogy have not yet broadly engaged with the African world and insights from Africana Studies and Geography. An African-centered approach facilitates people's reconnection to places and ecosystems in ways that do not reduce places to objects of conquest and things to be exploited for profitability and individual gain. Such an approach offers effective critiques of settler coloniser perspectives on the environment and deeper understandings of the relationship between worldview and ecologically sensitised education. Through examples from Africana Studies and Geography, this article provides an introduction to how an African-centered …

Detecting The Influence Of Best Management Practices On Vegetation Near Ephemeral Streams With Landsat Data, Matthew Rigge, Alexander Smart, Bruce Wylie, Kendall De Van Kamp

Natural Resource Management Faculty Publications

Various best management practices (BMPs) have been implemented on rangelands with the goals of controlling nonpoint sourcepollution, reducing the impact of livestock in ecologically important riparian areas, and improving grazing distribution.Providing off-stream water sources to livestock in pastures, cross-fencing, and rotational grazing are common rangeland BMPsthat have demonstrated success in drawing livestock grazing pressure away from streams. We evaluated the effects of rangelandBMP implementation with six commercial-scale pastures in the northern mixed-grass prairie. Four pastures received a BMPsuite consisting of off-stream water, cross-fencing, and deferred-rotation grazing, and two pastures did not receive BMPs. Wehypothesized that the BMPs increased the quantity …

Conflict Translates Environmental And Social Risk Into Business Costs, Daniel M. Franks, Rachel Davis, Anthony J. Bebbington, Saleem H. Ali, Deanna Kemp, Martin Scurrah

Geography

Sustainability science has grown as a field of inquiry, but has said little about the role of large-scale private sector actors in socio-ecological systems change. However, the shaping of global trends and transitions depends greatly on the private sector and its development impact. Market-based and command-and-control policy instruments have, along with corporate citizenship, been the predominant means for bringing sustainable development priorities into private sector decision-making. This research identifies conflict as a further means through which environmental and social risks are translated into business costs and decision making. Through in-depth interviews with finance, legal, and sustainability professionals in the extractive …
