School of Natural Resources: Faculty Publications

A secondary analysis of 1999–2002 Nebraska case-control data was conducted to assess the risk of non-Hodgkin lymphoma (NHL) associated with exposure to nitrate- and atrazine-contaminated drinking water. Water chemistry data were collected and weighted by well contribution and proximity of residence to water supply, followed by logistic regression to determine odds ratios (OR) and 95% confidence intervals (CI). We found no association between NHL risk and exposure to drinking water containing atrazine or nitrate alone. Risk associated with the interaction of nitrate and atrazine in drinking water was elevated (OR, 2.5; CI, 1.0–6.2). Risk of indolent B-cell lymphoma was higher …

Gathering, Buying, And Growing Sweetgrass (Muhlenbergia Sericea): Urbanization And Social Networking In The Sweetgrass Basket-Making Industry Of Lowcountry South Carolina, Patrick T. Hurley, Brian Grabbatin, Cari Goetcheus, Angela Halfacre

Environment and Sustainability Faculty Publications

Despite the visibility of natural resource use and access for indigenous and rural peoples elsewhere, less attention is paid to the ways that development patterns interrupt nontimber forest products (NTFPs) and gathering practices by people living in urbanizing landscapes of the United States. Using a case study from Lowcountry South Carolina, we examine how urbanization has altered the political-ecological relationships that characterize gathering practices in greater Mt. Pleasant, a rapidly urbanizing area within the Charleston-North Charleston Metropolitan area. We draw on grounded visualization—an analytical method that integrates qualitative and Geographic Information Systems (GIS) data—to examine the ways that residential and …

Quality Revolutions, Solidarity Networks, And Sustainability Innovations: Following Fair Trade Coffee From Nicaragua To California, Christopher M. Bacon

Environmental Studies and Sciences

Nicaraguan smallholder cooperative leaders working in partnership with a California-based small-scale roasting company pioneered an alternative approach to confronting the post-1999 coffee crisis. They built coffee tasting laboratories and integrated grassroots organizing efforts to create a national smallholder cooperative association that dramatically improved the quality, consistency, and prices from of the coffee they exported. Cooperative leaders used this development project to gain a more significant share of political economic power in a domestic coffee industry historically dominated by colonial powers, and corporate and domestic elites. This alliance between the artisanal small-scale roasting companies and cooperative leaders also proved that smallholders …

Experiments To Measure The Effects Of Timber Harvesting Equipment On Surface Lithic Scatters, Douglas J. Baughman

All Master's Theses

The importance of cultural resource preservation cannot be overstated; however local economies are at least as important. Due to conservative archaeological site protection practices in Region 5 of the United States Forest Service, the economy of Northeastern California is being adversely affected. In an attempt to help the Forest Service make more informed management decisions and improve the Northeastern California economy, I undertook experiments on the effects of timber harvesting on lithic scatters on Modoc National Forest. The experiments involved placement of 225 glass tiles (proxy lithics) in each of three plots subject to vehicle traffic and log dragging by …

The Elwha River Restoration: Landscape Change, Salmon, And Sense Of Place, Kelseyanne Johnson

This effort was the second year in a multiple-year venture to document the current …

Beyond Adaptive Capacity Checklists: Examining The Construction Of Capacity In Mexico City And Santiago, Patricia Romero-Lankao, Sara Hughes, Angélica Rosas-Huerta, Roxana Borquéz, Melissa Haeffner

Environmental Science and Management Faculty Publications and Presentations

Cities are vulnerable to a range of environmental hazards that are likely to be exacerbated by climate change: floods, droughts, poor air quality, and heat islands are a few examples. Assessments of this vulnerability often include an evaluation of a city’s adaptive capacity, or its potential to respond to changes in the frequency or severity of environmental hazards as well as its ability to take advantage of or mitigate these changes. For example, at the city (e.g., institutional) level, a common metric of adaptive capacity is the availability and effective use of information. In many cases, a city would receive …

Peer Influence Of Non-Industrial Private Forest Owners In The Western Upper Peninsula Of Michigan, Jillian R. Schubert, Audrey L. Mayer

College of Forest Resources and Environmental Science Publications

Understanding how non-industrial private forest (NIPF) owners gain and share information regarding the management of their property is very important to policy makers, yet our knowledge regarding how and to what degree this information flows over privately owned landscapes is limited. The work described here seeks to address this shortfall. Widely administered surveys with close-ended questions may not adequately capture this information flow within NIPF owner communities. This study used open-ended questions in interviews of clusters of NIPF owners to determine whether and to what extent owners influence each other directly (through conversations or referrals to sources of advice) or …

Unveiling Assigned Amount Unit (Aau) Trades: Current Market Impacts And Prospects For The Future, Elizabeth Lokey Aldrich, Cassandra L. Koerner

CAES Energy Policy Institute Faculty Publications and Presentations

The sale of assigned amount units (AAUs) from countries whose emissions have declined since their baseline year under the Kyoto Protocol has led critics to be skeptical of carbon markets due to the lack of actual emission reductions that occur as a result of these trades. This policy review describes the historical context of AAU trading, current market price and volumes, and environmental and economic impacts of the current AAU trading rules. Options for how to handle current, and prevent the creation of future, surplus AAUs are discussed.

West Of Eden: Resource Wars And Nature-Cultures In The American West, Scout Calvert

University of Nebraska-Lincoln Libraries: Faculty Publications

The richness and variety of the western landscape is what is at stake in hot political contests for the resources of the West: much of this public land is available to economic activity, including for mining, grazing, logging, and recreation. These uses threaten to outpace the land’s ability to renew these resources along with others, like air and water. Now in the first decade of the millennium with a new environmental awareness emerging partly from media coverage of global warming and peak oil, The American West at Risk offers a wide-ranging look at the degradation of the environment in the …

The Cenozoic Climatic And Topographic Evolution Of The Western North American Cordillera, C. Page Chamberlain, Hari T. Mix, Andreas Mulch, Michael T. Hren, Malinda L. Kent-Corson, Steven J. Davis, Travis Horton, Stephan A. Graham

Environmental Studies and Sciences

Herein we present oxygen isotope records from Cretaceous to Recent terrestrial sediments in the western North American Cordillera. The purpose of this analysis is to use oxygen isotope records to understand the coupled surface elevation and climate histories of this region through the Cenozoic. To do this we constructed δ¹⁸(O) maps of surface waters for time intervals that trace the development of topography of western North America. These maps are based on 4861 oxygen isotope analyses from both published (4478) and new (383) data. We determined the δ¹⁸(O) values of surface waters using paleotemperatures derived previously from floral assemblages and …

Scotts Bluff National Monument, Plant Community Resource Brief, Isabel Ashton, Mike Prowatzke

United States National Park Service: Publications

2011 Monitoring Status

Overview

In 2011, the first year of vegetation monitoring by the Northern Great Plains Network Inventory and Monitoring staff at Scotts Bluff National Monument, efforts resulted in the documentation of 79 plant species. This was the lowest number of species among parks sampled in 2011. Graminoid (grass and grass-like plant) species accounted for only 21 (27%) of the total species, but graminoid cover was much higher than that of any other plant type. Forbs were much more diverse, but did not provide as much foliar cover.

The 5 most abundant native non-graminoids were winterfat (Krascheninnikovia lanata …

Diversified Farming Systems: An Agroecological, Systems-Based Alternative To Modern Industrial Agriculture, Claire Kremen, Alastair Iles, Christopher M. Bacon

Environmental Studies and Sciences

This Special Issue on Diversified Farming Systems is motivated by a desire to understand how agriculture designed according to whole systems, agroecological principles can contribute to creating a more sustainable, socially just, and secure global food system. We first define Diversified Farming Systems (DFS) as farming practices and landscapes that intentionally include functional biodiversity at multiple spatial and/or temporal scales in order to maintain ecosystem services that provide critical inputs to agriculture, such as soil fertility, pest and disease control, water use efficiency, and pollination. We explore to what extent DFS overlap or are differentiated from existing concepts such as …

Food Security And Smallholder Coffee Production: Current Issues And Future Directions, Martha Caswell, V. Ernesto Méndez,, Christopher M. Bacon

Environmental Studies and Sciences

In recent years, there has been growing discussion within the specialty coffee industry about the preva- lence of seasonal food insecurity in coffee growing communities. The idea that coffee producers lack re- sources to feed themselves and their families flies in the face of Fair Trade and other sustainable coffee ini- tiatives, which were designed to ensure a viable livelihood and improved conditions for small-scale coffee farmers around the world. Though these certifications represent an important step toward delivering better prices to farmers, they are inadequate tools to stand alone against the formidable and entrenched barriers faced by this population. …

Producing Edible Landscapes In Seattle's Urban Forest, Rebecca J. Mclain, Melissa R. Poe, Patrick T. Hurley, Joyce Lecompte, Marla R. Emery

Environment and Sustainability Faculty Publications

Over the next decades, green infrastructure initiatives such as tree planting campaigns, and ecological restoration will dramatically change the species composition, species distribution and structure of urban forests across the United States. These impending changes are accompanied by a demand for urban public spaces where people can engage in practices such as gleaning, gardening, and livestock production. This article analyzes the institutional framework that undergirds efforts in Seattle, Washington to normalize the production and use of edible landscapes. We focus attention on the role of grassroots fruit gleaning groups and highlight their bridging function between Seattle's agriculture and forestry policy …

The Journal’S The Thing: Teaching Natural History And Nature Writing In Baja California Sur, John S. Farnsworth, Christopher Beatty

Environmental Studies and Sciences

The skills of making informed observations, synthesizing those observations, and communicating them effectively are central to the naturalist. Developing university courses that optimize instruction in these skills simultaneously can, however, be a challenge. Here we describe a program at Santa Clara University comprised of two integrated co-requisite courses, Writing Natural History (ENVS 142) and The Natural History of Baja (BIOL/ENVS 144). Lectures through the 10-week winter quarter expand students’ knowledge of the ecosystems and biodiversity of the Baja Peninsula and help them to develop descriptive writing skills. The courses culminate in a ten-day expedition to the Baja Peninsula and Isla …

The Social Dimensions Of Sustainability And Change In Diversified Farming Systems, Christopher M. Bacon, Christy Getz, Sibella Kraus, Maywa Montenegro, Kaelin Holland

Environmental Studies and Sciences

Agricultural systems are embedded in wider social-ecological processes that must be considered in any complete discussion of sustainable agriculture. Just as climatic profiles will influence the future viability of crops, institutions, i.e., governance agreements, rural household and community norms, local associations, markets, and agricultural ministries, to name but a few, create the conditions that foster sustainable food systems. Because discussions of agricultural sustainability often overlook the full range of social dimensions, we propose a dual focus on a broad set of criteria, i.e., human health, labor, democratic participation, resiliency, biological and cultural diversity, equity, and ethics, to assess social outcomes, …

Bird Red List And Its Future Development In Mongolia, Sundev Gombobaatar, D. Samiya, Jonathan M. Baillie

Of the 476 assessed native bird species of Mongolia, 10% were categorized as regionally threatened including Near Threatened. A further 0.6% were categorized as Critically Endangered (CR), 1.7% as Endangered (EN), 3.3% as Vulnerable (VU), and 4.4% as Near Threatened (NT). Almost 90% of Mongolian birds are categorized as Least …

Using Participatory Scenarios To Stimulate Social Learning For Collaborative Sustainable Development, Kris A. Johnson, Genya Dana, Nicholas R. Jordan, Kathy J. Draeger, Anne Kapuscinski

Dartmouth Scholarship

Interdependent human and biophysical systems are highly complex and behave in unpredictable and uncontrollable ways. Social and ecological challenges that emerge from this complexity often defy straightforward solutions, and efforts to address these problems will require not only scientific and technological capabilities but also learning and adaptation. Scenarios are a useful tool for grappling with the uncertainty and complexity of social-ecological challenges because they enable participants to build adaptive capacity through the contemplation of multiple future possibilities. Furthermore, scenarios provide a platform for social learning, which is critical to acting in the face of uncertain, complex, and conflict-laden problems. We …

Spatial Variations In Willingness To Pay For Water At The Local And Regional Scales Using Geographically Weighted Regression, Robyn Lane Dennis

Graduate Theses and Dissertations

Two decades of rapid urban growth and increasing per capita water consumption has left water providers in Northwest Arkansas concerned about their ability to meet future demand for water. Beaver Water District (BWD) is the largest of four regional water providers that draw from Beaver Lake, the only source of potable water in the region. Growth projections and per capita consumption patterns indicate that BWD could exhaust its raw water allocation as early as 2031. Municipal water customers served by BWD were surveyed about their stated priorities for water use, their water conservation behaviors, and their attitudes and perceptions about …
