A survey of 174 farmers was conducted in eight districts along the basin by using the random walk and quota sampling method. The questionnaire was designed to acquire data about the amount and types of pesticides …

“We’Re, Like, The Most Unhealthy People In The Country”: Employing An Equity Lens To Reduce Barriers To Healthy Food Access In Rural Appalachia, Kathryn Cardarelli, Emily M. Dewitt, Rachel Gillespie, Heather Norman-Burgdolf, Natalie Jones, Janet Tietyen Mullins

Dietetics and Human Nutrition Faculty Publications

Introduction

Obesity disproportionately affects rural communities, and Appalachia has some of the highest obesity rates in the nation. Successful policy, systems, and environmental (PSE) interventions to reduce obesity must reflect the circumstances of the population. We used a health equity lens to identify barriers and facilitators for healthy food access in Martin County, Kentucky, to design interventions responsive to social, cultural, and historical contexts.

Methods

We conducted 5 focus groups in Martin County, Kentucky, in fall 2019 to obtain perspectives on the local food system and gauge acceptability of PSE interventions. We used grounded theory to identify perceived barriers and …

A Crisis Of Kelp, Rachel L. Sherman

Capstones

Along with insects and lab-grown meat, for years seaweed has been lauded as a sustainable “food of the future” by the U.N. Food and Agricultural Organization. As the world increasingly turns to alternative foods in pursuit of a healthier Earth, seaweed has all the makings of an ecological savior. It’s plentiful — seaweeds and ocean algae make up roughly nine tenths of all the plant life on Earth — it’s cheap to harvest and get to market, packed with nutrition, and keeps oceans clean, absorbing more carbon dioxide and releasing more oxygen than the world’s rainforests.

But outside of Japanese …

An Economic Analysis Of Using Retired Vessels To Create Artificial Reefs In Costa Rica, Josué González

Electronic Theses and Dissertations

ABSTRACT

The Republic of Costa Rica is a Central American country with only 0.03% of the world’s landmass, but 5% of the world’s biodiversity, making it a leading ecotourism destination. Ecotourism is one of the main sources of revenue for the country, but the degradation of coastal reefs has resulted in a significant loss of financial income for developing areas. As a result, many of these areas are searching for methods to revert the degradation of coral reefs.

Artificial reefs play an important ecological role in marine ecosystems due to their complexity and size. They help in the development of …

Assessment Of Grain Safety In Developing Nations, Jose R. Mendoza

Department of Food Science and Technology: Dissertations, Theses, and Student Research

Grains are the most widely consumed foods worldwide, with maize (Zea mays) being frequently consumed in developing countries where it feeds approximately 900 million people under the poverty line of 2 USD per day. While grain handling practices are acceptable in most developed nations, many developing nations still face challenges such as inadequate field management, drying, and storage. Faulty grain handling along with unavoidably humid climates result in recurrent fungal growth and spoilage, which compromises both the end-quality and safety of the harvest. This becomes particularly problematic where there is little awareness about health risks associated with poor …

Market Trends In Food Consumption Expenditures Away From Home Prior To The Covid-19 Pandemic, Rebecca Weir

Undergraduate Economic Review

U.S. food consumption expenditures away from home increased from 19 percent of total food expenditures in 1955 to 48 percent in 2015. Simultaneously, female participation in the labor force grew by 52.7 million women from 35 to 57 percent, signifying increased opportunity cost for women to prepare meals at home. This research uses an ordinary least squares regression to examine socioeconomic factors influencing the rise in U.S. food consumption expenditures away from home in 2018. Results inform food production and service industries’ marketing strategies, and set the stage for whether a new pattern emerges in response to the COVID-19 pandemic.
