First Nations And Adaptive Water Governance In Southern Ontario, Canada, Thomas Dyck Jan 2017

First Nations And Adaptive Water Governance In Southern Ontario, Canada, Thomas Dyck

Theses and Dissertations (Comprehensive)

Water quality and quantity are prominent concerns for First Nations across Canada. The federal government shares the responsibility with First Nations to ensure water resources on-reserves meet the needs of First Nations. Federal approaches have been predominantly technical, focused on addressing issues related to infrastructure, maintenance, training, and monitoring. This approach is important. However, water issues concerning First Nations go beyond technical issues and relate to inadequate participation in decision making, poorly defined roles and responsibilities, and approaches to managing water resources on-reserve that have not accounted for local context. These issues parallel historical nation-to-nation (i.e., First Nations and federal …

Fire Data As Proxy For Anthropogenic Landscape Change In The Yucatán, Marco Millones, John Rogan, B. L. Turner, Benoit Parmentier, Robert Clary Harris, Daniel A. Griffith

Geography

Fire is one of the earliest and most common tools used by humans to modify the earth surface. Landscapes in the Yucatán Peninsula are composed of a mosaic of old growth subtropical forest, secondary vegetation, grasslands, and agricultural land that represent a well-documented example of anthropogenic intervention, much of which involves the use of fire. This research characterizes land use systems and land cover changes in the Yucatán during the 2000-2010 time period. We used an active fire remotely sensed data time series from the Moderate Resolution Imaging Spectroradiometer (MODIS), in combination with forest loss, and anthrome map sources to …

Estimating Energy Fluxes And Evapotranspiration Of Corn And Soybean With An Unmanned Aircraft System In Ames, Iowa, Áthila Gevaerd Montibeller

Dissertations and Theses @ UNI

Evapotranspiration (ET) is a key hydrological variable and has been studies to plan irrigation schedule, understand surface-atmospheric interactions, assess crop sensitivity to droughts, etc. On top of that, ET is a proxy for evaluating water availability in trees canopies and assess soil moisture content. The recent advent of the Unmanned Aircraft Systems (UAS) has presented new opportunities and challenges in mapping ET at a much finer scale and under various atmospheric conditions. In this research, we integrate traditional remote sensing techniques with the novel UAS technology to estimate ET and surface energy fluxes for a corn and soybean field near …

Spatial Competition In Airport Markets: An Application Of The Huff Model, Joel Heilman Jan 2017

Spatial Competition In Airport Markets: An Application Of The Huff Model, Joel Heilman

Dissertations and Theses @ UNI

Airports typically attract travelers from the immediate vicinity, but travelers may be willing to travel farther for better fares and more frequent flights. This study attempts to map the spatial variation of airport catchment areas using the Huff model. This model, originally designed to analyze retail store competition, can be applied to many forms of spatial competition, but it is a relatively unexplored approach in the context of airports. Unlike other air transportation travel choice models, it emphasizes spatial variation in market share and provides spatial representation in the form of a map. It is used in this study to …

Denver Food Deserts, Emily Connor Dec 2016

Denver Food Deserts, Emily Connor

Ursidae: The Undergraduate Research Journal at the University of Northern Colorado

Over time, socioeconomic factors, store type, and transportation distance have defined what types of foods are available to residents in urban areas and determining the overall well-being of people in that area, especially when it comes to obesity. Most cities, in one way or another, have neighborhoods that have these factors and create what is known as a food desert. Much like a desert lacking in water, a food desert lacks the availability of nutritious foods, and Denver is no exception. While Denver is known to be a healthy city, there are areas that share similar socioeconomic factors, store types, …

The New Normal? Climate Variability And Ecoviolence In Sub-Saharan Africa, Alfonso Sanchez Dec 2016

The New Normal? Climate Variability And Ecoviolence In Sub-Saharan Africa, Alfonso Sanchez

LSU New Orleans Theses and Dissertations

Climate change presents a wide range of concerns that can jeopardize international security. Among those concerns are neo-Malthusian worries of diminishing natural resources. Predictive models suggest that rainfall and temperature anomalies have the potential to reduce water basins, crop production, increase land degradation among other perils that threaten human security. This concern is particularly true in sub-Saharan Africa given the region’s strong dependence on rain-fed agriculture. Despite strong claims from various world leaders and scientists of a direct climate-conflict nexus, little empirical evidence has been devoted to find a systematic causal pathway of this kind. What is more, the literature …

Ironstone Gravel Types In Western Australia: Re-Purposing A Geological Survey To Improve Soil Management, Edward A. Griffin, Karen Holmes, Tim Overheu Dec 2016

Ironstone Gravel Types In Western Australia: Re-Purposing A Geological Survey To Improve Soil Management, Edward A. Griffin, Karen Holmes, Tim Overheu

Conference papers and presentations

The deeply laterised landscapes of Western Australia’s wheatbelt contain large amounts of ferruginous concretions or pisoliths, referred to locally as ironstone gravel. Soil surveys over the years have described ironstone gravel presence and abundance, and the state soil classification system recognises their importance in agriculture by designating ‘ironstone gravel soils’ at the highest level of the classification hierarchy. These gravels have generally been assumed inert in agricultural soils; however, farm trials and anecdotal experience suggest they may play a more active role in nutrient and water retention than previously recognised. Gravelly soil performance under dryland agriculture varies dramatically across the …

Mapping Trends In Bike Theft On Furman Campus From 2001 To 2016, Tindall Ouverson Dec 2016

Mapping Trends In Bike Theft On Furman Campus From 2001 To 2016, Tindall Ouverson

Earth and Environmental Sciences Presentations

The Furman University Police Department categorizes bike thefts as "bike larcenies" in their reporting system. However, most bike thefts on a college campus are not for monetary gain but as a means of transportation for opportunistic students. Though the goal of student bike thieves may be to get to class on time, the United States Department of Justice classifies them as "joyriders". Campus bike theft is a concern because it results in a monetary loss for students.

Habitat Quality Modeling For Bird Species At Furman University, Emma Cook Dec 2016

Habitat Quality Modeling For Bird Species At Furman University, Emma Cook

Earth and Environmental Sciences Presentations

In rapidly urbanizing areas, such as Greenville County in Upstate South Carolina, it is important to study habitat use and quality across land cover types in order to maximize conservation. Habitat fragmentation is a threat to many species of birds in areas with increasing development, especially those species that utilize larger forest patches for nesting and foraging. While land cover type and patch size are extremely important factors in determining habitat quality for birds, recent research has shown that the matrix of surrounding landscape proves to be very important as well. The landscape matrix, sometimes called landscape mosaic, considers the …

Soundscape Mapping: Spatial Variability Of Sound At Furman University, Alec Schindler Dec 2016

Soundscape Mapping: Spatial Variability Of Sound At Furman University, Alec Schindler

Earth and Environmental Sciences Presentations

Looking at the entire soundscape and studying its spatial variability can often give us important information about the health of the ecosystem. However, most previous studies only measure sound intensity, and are therefore limited in their depiction of the soundscape. Another tool for mapping soundscapes is SPreAD-GIS. This tool models sound propagation in an area. However, previous studies have only used it to evaluate the effects of noise pollution, but not applied it towards depicting the soundscape as a whole. I mapped the soundscape of Furman University’s campus using sound intensity as well as many different soundscape indices in order …

Evaluating Lithology As An Erosional Control On A Fluviokarst System In Northeastern Kentucky, Andrew K. Francis Dec 2016

Evaluating Lithology As An Erosional Control On A Fluviokarst System In Northeastern Kentucky, Andrew K. Francis

Theses and Dissertations

Longitudinal stream profiles can be used to evaluate landscape evolution. Lithology as a control on a stream profile is especially of interests because fluviokarst systems are characterized by the contact of carbonate and non-carbonate rocks at the surface. Due to the difference in weathering processes between carbonates and non-carbonate rocks, it is likely that there is a difference in their rates of erosion. Cave Branch and its tributary Horn Hollow, are fluviokarst systems located in northeastern Kentucky. This area is primarily comprised of sandstone and limestone. The objectives of this study were to determine if variation in lithology was creating …

Landsat 5 Thematic Mapper Reflectance And Ndvi 27-Year Time Series Inconsistencies Due To Satellite Orbit Change, Hankui Zhang, David P. Roy Dec 2016

Landsat 5 Thematic Mapper Reflectance And Ndvi 27-Year Time Series Inconsistencies Due To Satellite Orbit Change, Hankui Zhang, David P. Roy

GSCE Faculty Publications

The Landsat 5 Thematic Mapper (TM) sensor provided the longest single mission terrestrial remote sensing data record but temporally sparse station keeping maneuvers meant that the Landsat 5 orbit changed over the 27 year mission life. Long-term Landsat 5 TM reflectance inconsistencies may be introduced by orbit change induced solar zenith variations combined with surface reflectance anisotropy, commonly described by the Bi-directional Reflectance Distribution Function (BRDF). This study quantifies the local overpass time and observed solar zenith angle changes for all the Landsat 5 TM images available at two latitudinally separated locations along the same north-south Landsat path (27) in …
