The Human And Environmental Health Impacts Of Food Quality Among Emergency Food Providers, Alexina Cather Aug 2015

The Human And Environmental Health Impacts Of Food Quality Among Emergency Food Providers, Alexina Cather

Master's Projects and Capstones

Abstract

Human health and environmental health are inextricably entwined, and the ways in which we grow, process, package, transport, market, and consume food are critical factors for both human and environmental health. The current industrial food system in the United States has numerous adverse effects on environmental and human health, which significantly impact the millions of food insecure Americans who receive their nutritional needs from emergency food providers (American Public Health Association, 2007). The widespread food insecurity in the United States and the increasing prevalence of obesity among adults and children have drawn attention to the role that emergency food …

Protecting Ecosystems, Culture, And Human Rights In Chile Through Indigenous And Community-Conserved Territories And Areas, William G. Crowley

Capstone Collection

In environmental conservation circles around the world, the contributions of indigenous peoples and local communities to the sustainable maintenance of ecosystems and natural resources are being given increased attention. Whether for cultural, spiritual, economic, or other purposes, the use of traditional and local knowledge of habitat and resource management is slowly making its way into the modern environmental movement, and is being incorporated into the dominant conservation paradigms. These managed areas, known as Indigenous and Community-Conserved Territories and Areas, or ICCAs, are defined by the International Union for Conservation of Nature as “natural and/or modified ecosystems containing significant biodiversity …


The Price Of Snow: Albedo Valuation And A Case Study For Forest Management, David A. Lutz, Richard B. Howarth Jun 2015

The Price Of Snow: Albedo Valuation And A Case Study For Forest Management, David A. Lutz, Richard B. Howarth

Dartmouth Scholarship

Several climate frameworks have included the role of carbon storage in natural landscapes as a potential mechanism for climate change mitigation. This has resulted in an incentive to grow and maintain intact long-lived forest ecosystems. However, recent research has suggested that the influence of albedo-related radiative forcing can impart equal and in some cases greater magnitudes of climate mitigation compared to carbon storage in forests where snowfall is common and biomass is slow-growing. While several methodologies exist for relating albedo-associated radiative forcing to carbon storage for the analysis of the tradeoffs of these ecosystem services, they are varied, and they …


Using An Obcd Approach And Landsat Tm Data To Detect Harvesting On Nonindustrial Private Property In Upper Michigan, Riccardo Tortini, Audrey L. Mayer, Pieralberto Maianti Jun 2015

Using An Obcd Approach And Landsat Tm Data To Detect Harvesting On Nonindustrial Private Property In Upper Michigan, Riccardo Tortini, Audrey L. Mayer, Pieralberto Maianti

College of Forest Resources and Environmental Science Publications

Forest dynamics influence climate, biodiversity, and livelihoods at multiple scales, yet current resource policy addressing these dynamics is ineffective without reliable land use land cover change data. The collective impact of harvest decisions by many small forest owners can be substantial at the landscape scale, yet monitoring harvests and regrowth in these forests is challenging. Remote sensing is an obvious route to detect and monitor small-scale land use dynamics over large areas. Using an annual series of Landsat-5 Thematic Mapper (TM) images and a GIS shapefile of property boundaries, we identified units where harvests occurred from 2005 to 2011 using …

Impacts Of Consumer Horticulture On Stormwater And Nutrient Management: Investigating Public Perception, Knowledge, And Practices In The Shenandoah River Watershed, Christopher P. Parker

Masters Theses, 2010-2019

The South Fork Shenandoah River is a tributary to the Chesapeake Bay that is a significant contributor to nitrogen and phosphorus that enter the Bay and leads to increased eutrophication. These nutrients also cause problems in the South Fork Shenandoah River. The United States Environmental Protection agency has implemented strict regulation to reduce nutrients entering the Bay by developing the Chesapeake Bay TMDL. While the TMDL has strict regulation on wastewater treatment, agriculture, and industry, there are still sources of nutrients entering the Bay through unregulated sources. Urban/suburban runoff is one of these sources, particularly runoff from home owner’s lawns. …


Shorebird Migratory Stopover Responses To Local And Regional Change: Habitat Decisions In A Vanishing Landscape, Caitlyn Gillespie May 2015

Shorebird Migratory Stopover Responses To Local And Regional Change: Habitat Decisions In A Vanishing Landscape, Caitlyn Gillespie

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

Understanding the consequences of anthropogenic change for migratory species is challenging because although they have evolved to cope with environmental uncertainty, migrants still rely on predictable relationships within and among habitats to make informed decisions. Calidris shorebirds rely on ephemeral wetlands during northward migration through mid-continental North America, where favorable habitat conditions are annually and regionally unpredictable and increasingly altered by land-use change. During spring 2013 and 2014, we assessed Calidris habitat use in the Rainwater Basin (RWB) and the Prairie Pothole Region (PPR) at both local and landscape scales. Although anthropogenic change has altered the wetland landscape in both …

Using Network Models To Predict Steelhead Abundance, Middle Fork John Day, Or, Monica R. Blanchard May 2015

Using Network Models To Predict Steelhead Abundance, Middle Fork John Day, Or, Monica R. Blanchard

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

It is important in the management of threatened and endangered species to have informed population estimates. Population estimates are used to gage whether or not recovery goals are being met. When assessing Pacific salmonids this assessment involves sampling a small subset of the population and then scaling up to estimate larger populations units. This is complicated by the fact that fish populations are not evenly distributed along river systems but respond to fluctuating physical and biological stream properties. We used rapid assessment survey methods and the River Styles classification to explore fish-habitat relationships. River Styles is a classification system that …


Branching Out: How Virginia Can Strategically Use Trees To Combat Biodiversity Loss, Taylor Pfeiffer Apr 2015

Branching Out: How Virginia Can Strategically Use Trees To Combat Biodiversity Loss, Taylor Pfeiffer

Environmental Studies Senior Seminar Projects

Biodiversity loss is a particularly concerning effect of climate change because as greenhouse gas emissions increase global temperatures, decreases in the abundance and diversity of species has reduced ecosystem resiliency to these changes (Verchot et al. 2007). Weakened ecosystems and threatened species decrease the environment’s capacity to provide humans with services like safe drinking water, fuel, and protection from natural disasters, just to name a few (US EPA 2013). The agricultural industry plays a unique role in this environmental conversation, as farmland both contributes to climate change and is jeopardized by the negative effects created by the issue in a …


Taking Root: An Analysis Of The Best Method For Active Forest Regeneration In The Cloud Forest, Charlotte Startin Apr 2015

Taking Root: An Analysis Of The Best Method For Active Forest Regeneration In The Cloud Forest, Charlotte Startin

Independent Study Project (ISP) Collection

The cloud forest is a biodiversity hotspot and provides many vital ecological and economic services. Unfortunately, deforestation for pastures in the lower montane cloud forest is high. Many pastures become abandoned, leaving highly disturbed open areas of land where natural forest regeneration is poor. Human intervention to encourage ecological restoration is very important to re-establish the proper structure and functioning of the ecosystem. Forest regeneration projects are rare and often unsuccessful, which is why increased knowledge and skills of successful and practical methods for assisted regeneration are needed. The Inti Llacta Reserve in the Pichincha province in Ecuador protects a …

Fauna Census Of Intertidal Cliffs, Mangapwani, Zanzibar, Emily Jankowski Apr 2015

Fauna Census Of Intertidal Cliffs, Mangapwani, Zanzibar, Emily Jankowski

Independent Study Project (ISP) Collection

Due to their extreme variations in condition over the course of a day, intertidal zones are challenging environments. Organisms that live there must be prepared to cope with both exposure and submersion, not to mention the temperature variations that accompany these conditions. The differing tolerances and adaptations of various organisms to these conditions generally cause patterns of vertical zonation to occur in the intertidal zone, especially when the shore is steep and rocky. Understanding the ecology of shore environments is important to future conservation and management efforts. This study was conducted on a beach in Mangapwani, Zanzibar at at 6˚ …

Updated Marine Mammal Distribution And Abundance Estimates In British Columbia, Benjamin D. Best, Caroline H. Fox, Rob Williams, Patrick H. Halpin, Paul C. Paquet

Population Distribution and Habitat Collection

Information relating to the distribution and abundance of species is critical for effective conservation and management. For many species, including cetacean species of conservation concern, abundance estimates are lacking, out of date and/or highly uncertain. Systematic, line-transect marine mammal surveys were conducted in British Columbia’s (BC) coastal waters over multiple years and seasons (summer 2004, 2005, 2008, and spring/autumn 2007). In total, 10,057km of transects were surveyed in an 83,547km2 study area. Abundance estimates were calculated using two different methods: Conventional Distance Sampling (CDS) and Density Surface Modelling (DSM). CDS generates a single density estimate for each stratum, whereas DSM …
