Policy Implications Of The Covid-19 Pandemic On Food Security In Rural America: Evidence From Appalachia, Kathryn M. Cardarelli, Emily M. Dewitt, Rachel Gillespie, Rachel Hogg-Graham, Heather Norman-Burgdolf, Janet T. Mullins

Rural communities are disproportionally affected by food insecurity, making them vulnerable to the consequences of supply disruptions caused by the COVID-19 pandemic. While access to food was initially diminished due to food supply disruptions, little is known about the mechanisms through which federal emergency assistance programs impacted food access in rural populations. Through a series of five focus groups in spring 2021, we examined the impact of the COVID-19 pandemic on food access in a rural Appalachian community in Kentucky. Data were analyzed using a Grounded Theory Approach. Findings revealed the following four primary themes: food scarcity in grocery stores; …


Sugar-Sweetened Beverage Consumption Among Adults In Rural Appalachia, Heather Norman-Burgdolf, Emily M. Dewitt, Kathryn M. Cardarelli, Rachel Gillespie, Stacey A. Slone, Alison A. Gustafson Nov 2021

Sugar-Sweetened Beverage Consumption Among Adults In Rural Appalachia, Heather Norman-Burgdolf, Emily M. Dewitt, Kathryn M. Cardarelli, Rachel Gillespie, Stacey A. Slone, Alison A. Gustafson

Dietetics and Human Nutrition Faculty Publications

Sugar-sweetened beverage (SSB) consumption is decreasing nationally, yet intakes remain high in certain sub-populations as new varieties of SSBs are introduced. This study aims to expand on SSB intake patterns among adults living in Appalachia to develop policy, systems, and environmental (PSE) interventions to reduce consumption. Baseline cohort surveys were conducted to examine beverage consumption patterns of adults in one rural Appalachian county in Kentucky using a validated BEVQ-15 instrument. Ages were collapsed into three generational groups – Millennials (22–38 years), Generation X (39–54 years), and Boomers/Silents (≥55 years). Over half (n = 81; 54%) of the sample (n = …


Soil Macroinvertebrates Responses To Wildfires In The Blue Ridge Mountains, Usa, Madeline Olliff May 2021

Soil Macroinvertebrates Responses To Wildfires In The Blue Ridge Mountains, Usa, Madeline Olliff

Biology Theses

Fire has been a prevalent disturbance on Earth for millions of years. Around the globe there are several regions that have become fire adapted, including the Southeastern United States. There have been few studies examining the effects of wildland fires on soil macroinvertebrates in the Blue Ridge Mountains, in spite of the importance of these animals to soil processes and their contributions to the biodiversity of these ecosystems. During the fall of 2016, the Southeastern USA experienced numerous, large wildfires. These fires offered an opportunity to study the effects of wildland fire on soil macroinvertebrates. We sampled sites from three …


Development Of Mine Soils In A Chronosequence Of Forestry-Reclaimed Sites In Eastern Kentucky, Kenton L. Sena, Kevin M. Yeager, Christopher D. Barton, John M. Lhotka, William E. Bond, Kimberly J. Schindler Apr 2021

Development Of Mine Soils In A Chronosequence Of Forestry-Reclaimed Sites In Eastern Kentucky, Kenton L. Sena, Kevin M. Yeager, Christopher D. Barton, John M. Lhotka, William E. Bond, Kimberly J. Schindler

Lewis Honors College Faculty Publications

Surface mining for coal has contributed to widespread deforestation and soil loss in coal mining regions around the world, and particularly in Appalachia, USA. Mined land reforestation is of interest in this and other regions where forests are the dominant pre-mining land use. This study evaluated mine soil development on surface-mined sites reforested according to the Forestry Reclamation Approach, representing a chronosequence of time ranging from 0 to 19 years after reclamation. Soils were sampled in depth increments to 50 cm and analyzed for a suite of soil physical and chemical characteristics. Overall, soil fines (silt + clay) tended to …


A Study Of The Social, Cultural, And Environmental Influences On Appalachian Agriculture, Morganne May Apr 2021

A Study Of The Social, Cultural, And Environmental Influences On Appalachian Agriculture, Morganne May

Senior Theses

Appalachia, despite its rich history and abundant biological and cultural diversity, is commonly associated with a generalized notion of ignorance, resistance to progress, and "backwardness." This study aims to shed light on the socioeconomic, cultural, and environmental influences which have shaped the present food systems of Appalachia through a review of relevant literature. This history provides the necessary context to strategize a region-specific, socioeconomically and environmentally sustainable food system moving forward.


Assessing The Toxicity Of A Reconstituted Water Simulating Streams Influenced By Mountaintop Mining In Central Appalachia, Benjamin David Browning Jan 2021

Assessing The Toxicity Of A Reconstituted Water Simulating Streams Influenced By Mountaintop Mining In Central Appalachia, Benjamin David Browning

Theses, Dissertations and Capstones

Freshwater ecosystems in Central Appalachia experience increased concentrations of manganese (Mn) and total dissolved solids from the runoff of surface mines and valley fills. Biological communities have been impacted by these surface mining operations and it has been suggested that the increase in total dissolved solids may contribute to these negative effects, but standard laboratory toxicity tests have not found increased concentrations of total dissolved solids to have such negative effects as seen in the field. The elevated total dissolved solids in mining influenced streams may only be toxic in conjunction with another toxicant that is presence in these systems …


Maternal Proximity To Mountaintop Removal Mining And Birth Defects In Appalachian Kentucky, 1997-2003, Daniel B. Cooper Jan 2021

Maternal Proximity To Mountaintop Removal Mining And Birth Defects In Appalachian Kentucky, 1997-2003, Daniel B. Cooper

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

Background: Extraction of coal through mountaintop removal mining (MTR) alters many dimensions of the landscape, and explosive blasts, exposed rock, and coal washing have the potential to pollute air and water with substances known to increase risk of developmental and birth anomalies. Previous research suggests that infants born to mothers living in MTR coal mining counties have higher prevalence of most types of birth defects.

Objectives: This study seeks to examine further the relationship between MTR activity and birth defects by employing individual level exposure estimation through precise satellite data of MTR activity in the Appalachian region and maternal residence …


Environmental Controls On The Terrestrial Water Cycle In Forested Mountain Ecosystems., Luis Andrés Guillén Jan 2021

Environmental Controls On The Terrestrial Water Cycle In Forested Mountain Ecosystems., Luis Andrés Guillén

Graduate Theses, Dissertations, and Problem Reports

Water is a key resource to natural ecosystems and human societies alike, and the water cycle is fundamentally linked to the climate and the characteristics of catchments. However, the challenges posed by environmental change makes it imperative to understand how the water cycle is affected by biotic and abiotic factors, in particular, in areas that are crucial sources of water like forested headwater catchments. Therefore, this doctoral dissertation aims to advance the knowledge on the dynamics between climate, vegetation and landscape that determine the water balance of forested mountain ecosystems. This document presents five chapters, an introductory chapter, three standalone …
