Clean Water In Haiti, Hannah Mchugh

2012 Awards for Excellence in Student Research & Creative Activity - Documents

In the past few years, Haiti has been a topic that has been in the news here in the United States for many reasons. These reports typically show the faces of hundreds of starving and injured Haitians who live in turmoil and they discuss the disasters that have befallen the country. While these reports do not usually show the more pleasant aspects, they are relatively accurate in showing the state of the majority of the country. A major impact on a country that is in such a dire state is the presence and availability of clean water. But to understand …

The Effect Of Climate Change On Mongolian Herding Communities: Investigating The Current Prevalence Of Ecomigration And Community Perceptions Of And Responses To Migration In The Countryside, Rachael Diniega

Independent Study Project (ISP) Collection

The livelihoods of Mongolian herders depend on rangeland conditions, which are being threatened by land degradation and climate change. These changes may cause some Mongolian herders to move to a different land. Thus, the prevalence of ecomigration today and the perceptions and responses of herding communities to migrants were examined to understand ways government could form adaptation policy to climate change in the future. Interviews were conducted with both migrant and host herders as well as government officials in Mungunmorit, Tov and Delgerkhan, Khentii, including the state reserve Herlen Bayan-Olaang. A survey was used to evaluate the prevalence of ecomigration …

Independent Study Project (ISP) Collection

The purpose of this Independent Research Project is to make a documentary film about the effects modernization has had on the apple farming industry in Lower Mustang since its 1967 introduction. This film focuses on both the influence of Buddhi Ratna Sherchan, the senior horticulturalist who first introduced apples to Mustang, as well as the both positive and negative effects modernization and climate change have had on the region. Findings indicate a general movement towards mass production of apples that utilizes the new road to export high volume production. The heavy hail and rain fall brought about by climate change …

Implications For Old-Field Restoration: Diversity And Abundance Of Arbuscular Mycorrhizal Fungi In Soils Of Restored York Gum (Eucalyptus Loxophleba Subsp. Loxophleba) Sites Vs. Remnants., Jessica Wong

Independent Study Project (ISP) Collection

Arbuscular mycorrhizal fungi (AMF) may be critical to the restoration of ecosystem function in old-fields. Whether the diversity of the plant community is promoted by the AMF community or is the driving force of AMF diversity is unknown. We investigated two questions in the context of old-field restoration in southwestern Australia: 1) Does restoration of the plant community achieve the restoration of AMF and 2) Is AMF species diversity and abundance influenced by the plant species composition? Our study sites were located in the Ridgefield Experiment in the University of Western Australia’s “Future Farm”. Soil samples were collected from beneath …

Modeling The Impact Of Cracking In Low Permeability Layers In A Groundwater Contamination Source Zone On Dissolved Contamination Source Zone On Dissolved Contaminant Fate And Transport, Katherine W. Sievers

Theses and Dissertations

The storage and transport of a dense non-aqueous phase liquid (DNAPL) was evaluated using a numerical model. Many DNAPLs are used as solvents by the DoD and industry. The improper disposal and handling of these chemicals has led to long term contamination of groundwater. When spilled, a DNAPL will pool atop low permeability layers and slowly dissolve creating a contaminant plume. The dissolved contaminant within a low permeability layer serves as long-term sources of contamination once the source is removed. In this study, cracks are hypothesized to exist in the low permeability layers, allowing for enhanced transport. A numerical model …

The Ecology Of Pulse Events: Insights From An Extreme Climatic Event In A Polar Desert Ecosystem, U. N. Nielsen, D. H. Wall, B. J. Adams, R. A. Virginia

Dartmouth Scholarship

Climate change is occurring globally, with wide ranging impacts on organisms and ecosystems alike. While most studies focus on increases in mean temperatures and changes in precipitation, there is growing evidence that an increase in extreme events may be particularly important to altering ecosystem structure and function. During extreme events organisms encounter environmental conditions well beyond the range normally experienced. Such conditions may cause rapid changes in community composition and ecosystem states. We present the impact of an extreme pulse event (a flood) on soil communities in an Antarctic polar desert. Taylor Valley, McMurdo Dry Valleys, is dominated by large …

Groundwater Pollution Risk Assessment Under Scenarios Of Climate And Land Use Change In The Northern Great Plains, Ruopu Li

School of Natural Resources: Dissertations, Theses, and Student Research

Modeling groundwater vulnerability to pollution is critical for implementing programs to protect groundwater quality. Traditionally, groundwater vulnerability was modeled based on current hydrogeology and land use conditions. However, groundwater vulnerability is strongly dependent on factors such as depth-to-water, recharge and land use conditions that may change in response to future changes in climate and/or socio-economic conditions. For example, global warming may lead to northward shifts in cropping patterns and changes in crop mixes (and use of farm chemicals). Meanwhile, growing demands for biofuels are resulting in expanding corn acreage, and may lead to pressures to remove land from the Conservation …

Agriculture Futures: Potential Rural Land Uses On The Palusplain, Rodney Safstrom, Nicolyn Short Dr

Resource management technical reports

The purpose of this project was to identify agricultural land use options and opportunities within the Serpentine–Jarrahdale and Murray Shires, with particular focus on the Palusplain wetland section. The report will contribute to the Department of Planning’s natural resource management plan for the region and guide development of regional and local planning strategies. Historically, the Palusplain was a slowly moving, interconnected, seasonal wetland system with areas of higher ground. Extensive clearing and drainage occurred in the late 1800s through to the mid-1900s to facilitate agriculture; however, agriculture has been found to be a major contributor of nutrients to the system. …

Changing Water Quality In Great Pond: The Roles Of Lake Sediments, Invasive Macrophytes, And The Watershed, Colby Environmental Assessment Team, Colby College, Problems In Environmental Science Course (Biology 493), Colby College

Colby College Watershed Study: Great Pond (2012, 2010, 1998)

Eutrophication as a result of human activity is a threat to lake water quality globally and within the state of Maine. Great Pond, in the Belgrade Lakes region of Maine, has traditionally been an oligotrophic lake that is experiencing early signs of eutrophication and is currently classified as a mesotrophic lake. In the fall of 2012, the Colby Environmental Assessment Team (CEAT) measured the primary sources of nutrient loading to Great Pond including the catchment and the lake sediment, current water quality in Great Pond, and the potential impact of the variable milfoil invasion on the lake’s water quality. An …

Rural Inhabitant Perceptions Of Sandhill Cranes In Wintering Areas Of Northern Mexico, Ingrid Barcelo, Juan Carlos Guzmán-Aranda, Felipe Chávez-Ramírez, Larkin A. Powell

School of Natural Resources: Faculty Publications

Trends in the mid-continent population of sandhill cranes (Grus canadensis) indicate that the species is increasing. A large proportion of this population winters in northern Mexico where possible conflicts between local inhabitants and cranes can occur. We conducted interviews of 40 rural inhabitants living near wetlands used by cranes in three Mexican states. All interviewees had knowledge of cranes and were capable of describing them. The arrival of cranes affected 43% of interviewees. The negative effects were mainly destroyed crops with a subsequent diminished production. Seventy percent of those affected implemented scare tactics to deter the birds, while others (15%) …

Alaska encompasses several climate types because of its vast size, high-latitude location, proximity to oceans, and complex topography. There is a great need to understand how climate varies regionally for climatic research and forecasting applications. Although climate-type zones have been established for Alaska on the basis of seasonal climatological mean behavior, there has been little attempt to construct climate divisions that identify regions with consistently homogeneous climatic variability. In this study, cluster analysis was applied to monthly-average temperature data from 1977 to 2010 at a robust set of weather stations to develop climate divisions for the state. Mean-adjusted Advanced Very …

Drought Monitoring: Historical And Current Perspectives, Michael J. Hayes, Mark D. Svoboda, Brian D. Wardlow, Martha C. Anderson, Felix Kogan

National Drought Mitigation Center: Faculty Publications

Drought is a normal, recurring feature of climate throughout the world, with characteristics and impacts that can vary from region to region. Figure 1.1 illustrates the regular occurrence of drought within the United States between 1895 and 2010 with approximately 14% of the country, on average (plotted by black dotted line), experiencing severe to extreme drought conditions during any given year. Drought conditions can persist in a region for several years, as occurred in the United States in the 1930s, 1950s, and early 2000s, and tree ring and other proxy records confirm that multiple-year droughts are part of the long-term …

Future Opportunities And Challenges In Remote Sensing Of Drought, Brian D. Wardlow, Martha C. Anderson, Justin Sheffield, Bradley D. Doorn, James P. Verdin, Xiwu Zhan, Matthew Rodell

National Drought Mitigation Center: Faculty Publications

The value of satellite remote sensing for drought monitoring was first realized more than two decades ago with the application of Normalized Difference Vegetation Index (NDVI) data from the Advanced Very High Resolution Radiometer (AVHRR) for assessing the effect of drought on vegetation, as summarized by Anyamba and Tucker (2012, Chapter 2). Other indices such as the Vegetation Health Index (VHI) (Kogan, 1995) were also developed during this time period and applied to AVHRR NDVI and brightness temperature data for routine global monitoring of drought conditions. These early efforts demonstrated the unique perspective that global imagers like AVHRR could provide …

Microwave Remote Sensing Of Soil Moisture Science And Applications, Son V. Nghiem, Brian D. Wardlow, David Allured, Mark Svoboda, Doug Lecomte, Matthew Rosencrans, Steven K. Chan, Gregory Neumann

National Drought Mitigation Center: Faculty Publications

Soil moisture is a fundamental link between global water and carbon cycles and has major applications in predicting natural hazards such as droughts and floods (National Research Council, 2007). From precipitation data, soil wetness can be estimated by hydrological land-surface models. In the United States, preliminary precipitation data are based on measurements gathered from many active stations nationwide each month, and it takes 3–4 months to assemble final, quality-controlled data. In the western United States, some climate divisions may have no stations reporting in a particular month or may lack first- or second-order stations, and significant blockages by mountains limit …

Drought Triggers And Declarations: Science And Policy Considerations For Drought Risk Management, Linda Courtenay Botterill, Michael J. Hayes

National Drought Mitigation Center: Faculty Publications

This paper explores the value of triggers and declarations in the management of drought, bringing together two disciplinary perspectives, those of the public policy scholar and the climate scientist. These two perspectives highlight the complexity of the development and use of triggers in drought risk management by drawing on the experience of the United States, which has the most sophisticated system of drought triggers in the world, and that of Australia that has the most developed and longest standing national drought policy based on principles of risk management. The paper explores the advantages and disadvantages of triggers in managing drought, …

Watershed Sciences Faculty Publications

We used a stable isotope tracer to measure nitrogen (N) assimilation and transfer through Bull Trout Lake, a 0.3-km2 mountain lake in Idaho, specifically to explore the relative importance of pelagic and benthic producers. was added into the inflow stream above the lake during spring runoff and the resulting mass of tracer was measured within the various ecosystem compartments, including the outflow stream. Although a portion of the moved through the lake quickly due to a low hydraulic residence time during the addition, the tracer was also assimilated rapidly by seston in the water column and at a slower rate …

A Synoptic Perspective Of The Record 1-2 May 2010 Mid-South Heavy Precipitation Event, Joshua D. Durkee, Lee Campbell, Kyle Berry, Dustin Jordan, Gregory Goodrich, Rezaul Mahmood, Stuart Foster

High Plains Regional Climate Center: Staff Publications

During 1–2 May 2010, a series of strong thunderstorms led to 41, 57, and 43 tornado, severe wind, and severe hail reports, respectively, across portions of the southern United States. In addition to severe weather, these storms also distributed recordsetting rainfall amounts across the mid-South region, which contributed to historic flooding across portions of central and western Kentucky and Tennessee (Fig. 1). This heavy precipitation event was sampled by multiple surface observational networks, including (but not limited to) 48 research-grade automated stations from the Kentucky Mesonet (www.kymesonet .org), first-order automated stations from the National Weather Service (NWS; www.ncdc.noaa.gov /oa/ncdc.html), and …

The Feasibility Of Switchgrass For Biofuel Production, Rob Mitchell, Kenneth P. Vogel, Daniel R. Uden

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Switchgrass research has been conducted cooperatively by the US Department of Agriculture and the University of Nebraska since the mid-1930s, with a primary focus on bioenergy since 1990 at several institutions. Progress has been made in switchgrass breeding and genetics, molecular genetics, establishment, fertility management, production economics, production energetics, harvest and storage management, ecosystem services and ethanol yield. A complete field-validated biomass production system has been developed for the Midwest and Central Plains. Even with favorable economic and sustainability results from field trials, switchgrass for bioenergy has not been adopted on a large scale. Lack of adoption is likely due …

Thermal-Based Evaporative Stress Index For Monitoring Surface Moisture Depletion, Martha C. Anderson, Christopher R. Hain, Brian D. Wardlow, Agustin Pimstein, John R. Mecikalski, William P. Kustas

National Drought Mitigation Center: Faculty Publications

The standard suite of indicators currently used in operational drought monitoring reflects anomalous conditions in several major components of the hydrologic budget—representing deficits in precipitation, soil moisture content, runoff, surface and groundwater storage, snowpack, and streamflow. In principle, it is useful to have a diversity of indices because drought can assume many forms (meteorological, agricultural, hydrological, and socioeconomic), over broad ranges in timescale (weeks to years), and with varied impacts of interest to different stakeholder groups. Farmers, for example, may be principally interested in soil moisture deficits, river forecasters will focus on streamflow fluctuations, and water managers will be concerned …
