Index-Based Insurance And Risk Management Among Nomadic Mongolian Herders , Kelsey Larson Dec 2014

Index-Based Insurance And Risk Management Among Nomadic Mongolian Herders , Kelsey Larson

Independent Study Project (ISP) Collection

Mongolian herders must contend with the risk of dzuds, harsh winters that can kill large numbers of livestock. To do so, they use a mixture of formal financial tools and traditional risk mitigation techniques. This paper is a study of the interaction between the Mongolian Index-based Livestock Insurance Program and traditional informal risk mitigation techniques. The researcher interviews herders in Bulgan soum, Arhangai aimag and Galuut soum, Bayanhongor aimag to compare the IBLI program’s impact in a community that has had IBLI since 2006 and one that only received IBLI in 2012. This study finds that insurance purchase is ...


Stream Temperature Management In The Tualatin Watershed: Is It Improving Salmonid Habitat?, Raymond Banks Hennings Nov 2014

Stream Temperature Management In The Tualatin Watershed: Is It Improving Salmonid Habitat?, Raymond Banks Hennings

Geography Masters Research Papers

The purpose of this paper is to examine the literature from scientific and governmental entities that describes the problems with elevated stream temperatures in the Tualatin basin, the actions being taken to resolve those problems, and to assess whether these actions are meeting the goal of improving salmonid habitat in the basin. Elevated stream temperatures are considered a pollutant under the US Clean Water Act (Clean Water Act 1972, as amended) because increased stream temperatures can be harmful to native aquatic biota, particularly salmonid fish species that have evolved to use cold water (IMST 2004).

Michigan's Clay Bluffs: The Description And Comparison Of An Erosion-Dependent Natural Community, Nathaniel G. Fuller Aug 2014

Michigan's Clay Bluffs: The Description And Comparison Of An Erosion-Dependent Natural Community, Nathaniel G. Fuller

Master's Theses

The clay bluffs of Michigan are a natural community found along the shores of the Great Lakes. Groundwater is found to be critical to sustaining the alkaline wetlands on the face of the bluff as well as the source of most erosion events. The clay bluffs are unusual in their vegetation, disturbance regime and geographical context. This thesis focuses primarily on describing seeping clay bluffs and exploring the comparison to other natural communities. The purpose of this is twofold, to better understand the ways in which natural communities are described as distinct from one another, and to assess the distinctness ...


The Retention, Revival, And Subjugation Of Indigenous Fire Knowledge Through Agency Fire Fighting In Eastern Australia And California, Christine Eriksen, Don Hankins Jul 2014

The Retention, Revival, And Subjugation Of Indigenous Fire Knowledge Through Agency Fire Fighting In Eastern Australia And California, Christine Eriksen, Don Hankins

Christine Eriksen

This article explores the potential impact of training and employment with wildfire management agencies on the retention of Indigenous fire knowledge. It focuses on the comparative knowledge and experiences of Indigenous Elders, cultural practitioners, and land stewards in connection with “modern” political constructs of fire in New South Wales and Queensland, Australia, and California in the United States of America. This article emphasises the close link between cross-cultural acceptance, integration of Indigenous and agency fire cultures, and the ways in which knowledge types are shared or withheld. While agency fire fighting provides an opportunity for Indigenous people to connect and ...


Climate Change Vulnerabilities: Case Studies Of The Maldives And Kenya, Katherine A. Peinhardt May 2014

Climate Change Vulnerabilities: Case Studies Of The Maldives And Kenya, Katherine A. Peinhardt

Honors Scholar Theses

This paper examines the political and social vulnerabilities of climate change, with the use of two salient case studies, the Republic of the Maldives and Kenya as exemplars of effects observed and projected. The susceptibilities for each nation are examined, with unique sensitivities highlighted and common themes synthesized between the two states. Examples of existing conflict, and implications of projected territorial conflict will be discussed. Policy outcomes will also be discussed for the situation of each nation, each with its own set of contextual sensitivities in the face of climatic shifts. Generalized policy options will be proposed for the common ...


Integrating Seismic Activity Into Land Use Management: A Case Study From Central Arkansas Using Hazus Software Application, Robert Dean Breashears May 2014

Integrating Seismic Activity Into Land Use Management: A Case Study From Central Arkansas Using Hazus Software Application, Robert Dean Breashears

Theses and Dissertations

Almost 20 years after a remarkable swarm of more than 30,000 micro-earthquakes, a new swarm revisited the same region of central Arkansas, less than 30 miles northeast of Conway, Arkansas. A main shock on May 4, 2001 of magnitude MR = 4.4 was followed by a large number of aftershocks in a small crustal volume about 2,500 events for about 2 months. Preliminary locations of aftershocks from the portable network together with the locations based on data from regional networks lead us to conclude that both swarms (2001 and 1982) occupy virtually the same crustal volume. In following ...


A Multidimensional Analysis Of The Great Green Wall: The Environmental And Social Effects Of Reafforestation In Senegal, Anna Eugenia Alsobrook May 2014

A Multidimensional Analysis Of The Great Green Wall: The Environmental And Social Effects Of Reafforestation In Senegal, Anna Eugenia Alsobrook

Masters Theses

The north-central region of Senegal is home to the Great Green Wall (GGW)—a reafforestation project aimed at restoring decades–old, degraded land conditions by establishing tree belts and community gardens. Its presence on the ground has changed the local landscape and altered the social institutions governing the daily lives of the people it aims to protect.

My study is an in-progress assessment of the GGW towards its two major goals: 1) improving the lives of the people of the Sahel and increasing their capacity to adapt to climate change and drought, and 2) improving the state of the ecosystem ...


Salmonid Habitat Restoration On The Chocolay River, Michigan, Ross J. Crawford Apr 2014

Salmonid Habitat Restoration On The Chocolay River, Michigan, Ross J. Crawford

Master's Theses

This project seeks to improve salmonid habitat quality by improving riparian vegetation on the adjacent banks (from toe to terrace) on the Chocolay River in Michigan's Upper Peninsula. Quantities of large woody debris (LWD) were also analyzed to determine the heterogeneityof stream habitats, or channel roughness. Percentages of rock, gravel, sand, and silt were analyzed to determine spawning habitat quality. As the proportions of fines (


No Fracking Way! A Study On The Spatial Patterns Of And Changes In Perception And Distance From A Michigan Horizontal Hydraulic Fracturing Site, Shannon Mcewen Apr 2014

No Fracking Way! A Study On The Spatial Patterns Of And Changes In Perception And Distance From A Michigan Horizontal Hydraulic Fracturing Site, Shannon Mcewen

Master's Theses

The research investigates whether Michigan residents' perception of risk from an oil and natural gas (ONG) well site that employs the use of horizontal hydraulic fracturing (fracking) changes with distance. The research goal is to determine if residents that live farther from a fracking site perceive it to be more dangerous than those who live closer. Secondary research goals include determining if increasing distance from a fracking site cause residents to overestimate their proximity to a fracking site and if gender and education levels have an effect on residents' perception levels. Data were collected from residents in three counties in ...


Managing Dispersed Recreation In The Allegheny National Forest, Anne Santa Maria Apr 2014

Managing Dispersed Recreation In The Allegheny National Forest, Anne Santa Maria

Master's Theses

In the Allegheny National Forest, an unregulated dispersed camping policy has led to significant impacts to the natural environment. This study used data gathered from visitor surveys, interviews with managers, and environmental conditions of campsites to recommend management actions for campsites along seven roads in the National Forest. The seven road areas fell into two categories. Primitive recreation was more common in some areas and solitude was more highly valued by campers. Other areas had more frequent visitor use, motorized camping, and solitude was less important to campers. These factors influenced management recommendations, which include designing and constructing campsites to ...

Habitat wetlands in Libya may be grouped into several distinct varieties, according to climate, water supply, soils, and biotic diversity. They include coastal Sabkhas (salt marshes), karst lakes, Wadi estuaries, below sea-level desert lakes, and balat flats (playas) where the soil is saturated part of some rainy seasons forming a kind of ephemeral, shallow lakes in pre-desert areas. The most prominent, however, are the extensive coastal salt marshes. These have either organic or inorganic soils, or both, depending on their location and climate conditions. Soils common to most coastal wetlands are composed largely of inorganic material in the form of ...


Sustainability Policy’S Inherent Dilemmas – Exemplified Via Critical Examination Of The Las Vegas Metropolitan Sustainability Campaign, Kathryn A. Zimmerman Jan 2014

Sustainability Policy’S Inherent Dilemmas – Exemplified Via Critical Examination Of The Las Vegas Metropolitan Sustainability Campaign, Kathryn A. Zimmerman

All Master's Theses

In response to a dual problem of critical water scarcity and rapid population growth, leaders of metropolitan Las Vegas implemented a region-wide, internationally marketed sustainability campaign. Preliminary studies found that, while sustainability policy attains its rhetorical goals, solutions initiated not only perpetuate but also purposefully expand the original dual problem to justify continuous water resource acquisitions. To examine this sustainability conundrum constructed by leadership—problem-perpetuation rather than problem-resolution—a critical examination in resource management asked two basic questions: what is being sustained and by what means? Via this inquiry, specific processes by which leaders perpetuate problems can be identified; and ...


Paradoxes Of Democratisation: Environmental Politics In East Asia, Mary Alice Haddad Dec 2013

Paradoxes Of Democratisation: Environmental Politics In East Asia, Mary Alice Haddad

Mary Alice Haddad

This chapter examines environmental politics in four polities that run the full spectrum of political regimes: mainland China (authoritarian), South Korea and Taiwan (newly democratic), and Japan (mature democracy). The chapter argues that variation in environmental politics in each place resulted primarily from the timing of their environmental movements, with subsequent movements learning from predecessors and gaining increasing access to global NGO networks. Paradoxically, when environmental movements became linked to democratization movements (in South Korea and Taiwan), they also became linked to political parties, which hindered access to government policymaking when non-allied parties were in power.
