Agricultural Efficiency And The End Of The Oil Age; Building A Future Of Longevity, Keith Mchugh

Pomona Senior Theses

This thesis uses an efficiency analysis of agricultural systems to assert that, in lieu of rising prices of fossil fuel, people need to come into more direct contact with their food systems. With a switch to smaller, more efficient farms that rely less on fossil fuel and are connected with the communities they supply for, we can avoid an energy crisis turning into a famine. These smaller-scale systems can help create self-contained, carbon-neutral communities.

Roger Williams Park Edible Forest Garden, Mark S. Scialla

Senior Honors Projects

An edible forest garden is a low-maintenance system that uses edible native and regionally-adapted plants arranged in beneficial relationships to meet human, wildlife and ecosystem needs. The forest garden in Roger Williams Park will transform underutilized urban land into a highly productive parcel producing market-viable fruits, nuts, vegetables, medicine and fiber. Forest gardens mimic natural forest systems in architecture and complexity. The design follows ecological principles to create a system that promotes biodiversity and enhances the surrounding ecosystem. This project also demonstrates the potential to grow food and create land-based livelihoods in the city.

Food System Assessment, Virgene Hanna, Rosyland Frazier, Khristy L. Parker, Irena Ikatova

ISER Reports

Food assessments are conducted for different reasons such as creating a more sustainable commercial food production system or to target particular policies. The main focus of this effort was to locate indicators that could be updated regularly so current information would be readily available and so that changes or trends could be monitored. Without knowing the current state of food-related indicators it’s difficult to make informed decisions about which issues and goals are priorities. We start with an overview of the food system model we used. Chapter 2 is a demographic overview of Alaska’s residents. The next five chapters present …

Not Your Family Farm Apiculture In South,Central Montana, Miles Lewis

Great Plains Quarterly (through 2013)

The rolling prairies and sheltering mountain ranges of the Upper Musselshell Valley in Montana are nearly perfect for cattle and sheep grazing. Some areas, more topographically similar to the Great Plains than to the mountainous West, are (at least in wet years) highly conducive to growing alfalfa or wheat. Overall, the pastoral setting calls to mind images of weathered cowboys, grizzled sheepherders, and stoic farmers. However, closer inquiry into the region's agriculture reveals that cattle and wheat are by no means the only product being harvested from the land. Found buzzing around flowering foliage or swarming the rearing hindquarters of …

Produce Your Own: A Community Gardening Program, Jolynn Miller, Shannon Arnold

Journal of Extension

Many County Extension offices offer an adult Master Gardener Program, which includes advanced gardening training, short courses, newsletters, and conferences. However, with the comprehensive training provided comes a large time commitment. The Produce Your Own program was created to introduce adults to gardening in a similar manner, but with shorter, less demanding, and less technical sessions. The outreach program consisted of a series of four interactive sessions focused on plot design, crop selection, garden maintenance, harvesting, and preserving. The content can be adapted in many ways for adults, seniors, youth, and other audiences, which allows Extension to reach larger audiences.

Effect Of Level Of Farm Mechanization Early In Life On Bone Later In Life, Lacey A. Mccormack, Teresa L. Binkley, Bonny Specker

Health and Nutritional Sciences Faculty Publications

OBJECTIVE: To determine whether an active rural lifestyle during childhood and adolescence, defined as low farm mechanization, was associated with bone measures later in life.
METHODS: DXA bone data from total body, hip and spine, and pQCT data from 4% and 20% distal radius were obtained on 330 individuals (157 women) aged 20-66 years who farmed at least 75% of their lives. Primary bone outcomes included areal bone mineral density (aBMD), aBMD Z-scores, cortical and trabecular volumetric BMD, cortical thickness and periosteal circumference. Relationship between bone and recall of level of farm mechanization as a child was determined after stratifying …

United States Public Policy Regarding Genetically Modified Foods, Jennifer A. Zimmerman

Theses & ETDs

Genetically modified foods are produced, sold and consumed in the United States, and are undifferentiated from conventional foods. Policy discrepancies in the US, EU and Japan may stem from public opinion, agricultural system design, and other social and economic factors. The purpose was to investigate the current system for labeling foods derived from genetically modified organisms, and to determine if this was desirable by those affected. Through examination of scientific studies on the safety and potential effects of genetically modified foods, evaluation of public opinion poll and survey results, and comparison of the laws and regulatory bodies governing food labeling …

The Impact Of Seasonal Movements By Ovigerous American Lobsters (Homarus Americanus) On Egg Development And Larval Release, Jason Seth Goldstein

Doctoral Dissertations

The American lobster (Homarus americanus) supports one of the most economically successful fisheries in the Gulf of Maine. The continued success of this fishery is attributed in part to vigilant broodstock conservation through the preservation of ovigerous (egg-bearing) females. Previous studies of ovigerous lobster movements indicate that some, if not most, display seasonal inshore-to-offshore movement patterns. While it has been assumed that these movements serve to expose eggs to thermal regimes that are optimal for development, this theory has never been rigorously tested. In Chapter 1, I present results from ultrasonic tracking studies designed to determine if lobsters in coastal …

Flatfish Stock Enhancement: Examining Conditioning Strategies To Promote Success, Michelle Lynn Walsh

Doctoral Dissertations

Conditioning is the process of providing individuals reared for stock enhancement with some degree of "wild" experience prior to release. Flatfish trained for "wild" conditions may more easily and successfully transition to natural environments. This dissertation identifies strategies that optimize feeding-related performance of flatfish in the hatchery and subsequently post release in the wild.

The influence of live feed conditioning on feeding performance of juvenile winter flounder, Pseudopleuronectes americanus, was investigated. In the hatchery, fish reared on live feeds exhibited significantly higher survival (P < 0.0001) and growth (P < 0.01) than those reared on formulated feed. Once released into cages in the wild, amphipodreared fish had higher mean Stomach Contents Index and RNA/DNA of all feed types, including wild fish. Wild and worm-reared fish exhibited the most similar survival, baseline RNA/DNA values, overall stomach fullness, and diet composition profiles over time.

Pre-release, experimental cage conditioning was conducted for stocking Japanese flounder, Paralichthys olivaceus, in Wakasa Bay, Japan. …

Eating Quality And Variability In Carotenoid Content And Profiles In Winter Squash And Sweet Potato, Jennifer Bonina Noseworthy

Doctoral Dissertations

A comprehensive study at the New Hampshire Agricultural Experiment Station (NHAES) of 16 winter squash cultigens (Cucurbita spp.), including inbred lines and open pollinated and F1 hybrid cultivars from the University of New Hampshire breeding program, was undertaken to determine dry weight (%DW), soluble solids contents (%SSC) and carotenoid contents of mesocarp tissue, major attributes for determining acceptable eating quality and nutritional content. Data were recorded at harvest, either 40 or 60 days after pollination (DAP), and after 30 and 60 days of storage at 14 °C. Carotenoid contents were determined spectrophotometrically and using high performance liquid chromatography (HPLC).

Livestock And Climate Change – Annotated Bibliography, Julia Christian, Andrew Kirchner, Derek Nelson, Jessica A. Wentz

Sabin Center for Climate Change Law

Over the past two decades, efforts to address climate change have primarily focused on reducing carbon dioxide (CO2) from fossil fuel combustion. The potential contribution of livestock production to climate change has been largely overlooked. Recent scholarship suggests that activities related to livestock production constitute a significant proportion of anthropogenic greenhouse gas (GHG) emissions. Although estimates of livestock’s contribution to our overall GHG emissions range broadly – from 18% to 51% – there is no question that this impact warrants serious consideration from policy makers.

Coalitions In The Jungle: Advancing Animal Welfare Through Challenges To Concentration In The Meat Industry, Lis Kamila

Animal Law Review

The meat processing conglomerates that currently control the majority of the market share in the meatpacking industry are responsible for its most systemic animal abuses. Increased concentration has enabled these larger processors to dictate animal treatment standards maintained by meat producers, most of whom have caved to economic pressure and moved their animals from small farms into Concentrated Animal Feeding Operations. Animal welfare proponents have failed to adequately challenge the concentration of the meat industry and in 2012 have yet to fully explore strategies made available by the Packers & Stockyards Act of 1921 (PSA). This Article proposes that a …

Markers Of Health Status In Pasture-Fed Versus Total Mixed Ration-Fed Jersey Dairy Cattle, Megan Lee Seneca

Master's Theses and Capstones

Milk from pastured cows contains more beneficial fatty acids than milk from total mixed ration (TMR) fed cows. No studies have been done comparing health status in cows from each system. This study used pastured vs. TMR fed Jersey cows to measure levels of cortisol, haptoglobin (Hp), somatic cells, and production within and between farms over time.

Cortisol was significantly different between farms with means of 126.78 and 93.64 ng/ml for pastured and TMR groups, respectively. Levels in pastured cows trended with temperature and humidity. There was no significant difference in Hp levels between farms though levels did change over …

Development And Evaluation Of Interspecific Cucurbita Maxima X Cucurbita Moschata Hybrids For Processing Squash, Jacob Uretsky

Master's Theses and Capstones

Interspecific hybrids derived from crosses of Cucurbita maxima Duch. x C. moschata Duch. have been utilized for taxonomic studies and introgression of advantageous traits, as well as for cultivation for fresh market squash. The present study involves the development and evaluation of C. maxima x C. moschata F1 hybrids for use as processing squash. Crosses were performed in the summers of 2009, 2010, and 2011 between inbred bush C. maxima breeding lines and vine C. moschata cultigens, and the resulting progeny were evaluated in the greenhouse and field in 2010 and 2011 for phenological growth traits, fruit traits, and fruit …

Effects Of Whole-Tree Harvesting On Site Productivity And Species Composition Of A Northern Hardwood Forest, Gabriel Ethan Roxby

Master's Theses and Capstones

Whole-tree harvesting is widely used in the northeastern United States to supply biomass energy plants with fuel, but questions remain regarding its long-term sustainability. To assess its effects on the northern hardwood forests that make up a significant portion of northern New England, we conducted two regeneration surveys in 2010 and 2011 covering thirty-three small clearcuts. We measured whole-tree (WTH) and conventionally harvested (CH) sites in New Hampshire and Maine, and compared the productivity and species composition of the 10-14 year old regeneration. No significant difference was observed in height, diameter or calculated biomass of stems > 2m in height. Despite …

Variations In Carotenoids And Retinol In Milk And Cheese From Jersey Cows At An Organic Dairy Compared To A Conventional Dairy Over A Pasture Season, Amy Rose Beliveau

Master's Theses and Capstones

Carotenoids, widely distributed in nature, are considered to be potentially beneficial in the prevention of a variety of diseases including cardiovascular disease, certain cancers and eye diseases. As humans are unable to synthesize carotenoids, the diet is the only source of these beneficial components. Carotenoid concentration in cow's milk varies greatly as a result of feeding practice and season, but no research thus far has investigated these variations in Jersey cows over an entire pasture season. The objectives of this experiment were to 1) determine the differences in concentrations of carotenoids and retinol in milk from cows consuming different diets, …

Are There Roles For Technical Communicators In Small Community Food Systems?, Brent William Chisholm

All Graduate Theses, Dissertations, and Other Capstone Projects

The author explores the viability of incorporating technical communication genres, practices, and theory, into various components of small community food systems. He argues that certain types of food systems and users in those food systems allow technical communicators to participate in ways aligning with genres of conservation writing described by Johnson-Sheehan and Morgan (2009). He also incorporates ideas about authorship, describing that technical communicators can improve food systems by reconciling disparate agricultural technical material, advocacy for action, and the articulation of previously non-existent food systems.

Hemoglobin Type, Egg Buoyancy, And Antifreeze Glycoprotein Production As Mechanisms For Adaptive Variation In Gulf Of Maine Atlantic Cod (Gadus Morhua), Amanda R. Clapp

Master's Theses and Capstones

Three physiological traits were examined to compare captive populations of winter- and spring-spawning cod from the Gulf of Maine, as differences in these traits have been observed in other locally-adapted subpopulations. Daily mean neutral buoyancy of hatchery-spawned eggs was observed at three temperatures (5, 10, and 12°C) and three photoperiods (15:9, 9:15, and 24:0 L: D) at 12°C. Body fluids of larvae held at 0°C for five days were tested for antifreeze glycoproteins (AFGPs) to determine the onset of AFGP production. Juveniles held at 0°C were bled between 20 and 35 days to determine induction time for AFGP production. Hemoglobin …

Illinois Local Food Systems: A Geospatial Analysis, Abu S. Khan

Research Papers

Recently, more attention has been paid to studies of local food systems that are specific to a particular place as a potential solution for providing healthy food, reducing carbon emissions, and promotion of local agriculture sustainability. In the United States, the demands of locally produced foods have increased substantially in recent years. There are several reasons for this increase, including long-distance food transportation’s contribution to greenhouse gas emissions, the community food-security movement, and the increase of negative environmental problems related to large scale agriculture, etc., have contributed to the shift of attention from global food systems to local ones. Moreover, …

The Increasing World Population: A Call For Entrepreneurial Leadership & Innovation, Connie I. Reimers-Hild

Kimmel Education and Research Center: Presentations and White Papers

According to the United Nations, the world’s population hit 7 billion on October 31, 2011. The United Nations is projecting the world population to reach 9.3 billion by 2050. The new population landmark set off alarms in governments and organizations around the world. Most of the growth will occur in the poorest and least developed regions of the world, which already must work to resolve issues related to shortages of quality food, soil, air and water. Many people living in these countries also lack access to education, healthcare and global political capital. This white paper discusses the importance of innovation …

Agricultural Irrigation Using Municipal Effluent, Charles M. Burt

BioResource and Agricultural Engineering

The paper describes the development of a design and management plan for disposing of secondary effluent originating in the urban communities. It highlights the differences in approach that a public utility must take, versus a typical agricultural irrigation application. Costs and requirements for municipal effluent irrigation are many times greater. The complexity of regulations and agency procurement procedures relegates the actual irrigation system design to a relatively small role in the total project.

The Transformation Of China’S Agriculture System And Its Impact On Southeast Asia, Phoebe Mingxuan Luo, John A. Donaldson, Qian Forrest Zhang

Research Collection School of Social Sciences

The increased role for agribusiness and larger scale production in China’s agricultural system is limited by China’s severe lack of arable land. The Household Responsibility System provides farmers a measure of power, hampering agribusiness from acquiring land needed for expansion. Some Chinese companies have sought cheaper and often more accessible land in nearby regions, including Southeast Asia. While such investments have the potential to deliver benefits, including increased productivity, structural constraints such as weak land ownership and environmental laws, highly unequal distribution of land and underdevelopment of peasant organizations prevent many poorer farmers from benefiting from these investments.

Characterizing Textural Attributes Of Rainbow Trout, Oncorhynchus Mykiss, Fillets As Affected By Age, Sterility, And Storage Regimen, Aunchalee Aussanasuwannakul

Graduate Theses, Dissertations, and Problem Reports (ETD)

Trout fillets, subjected to refrigeration (4°C; 3 or 7 d) by frozen storage (-25°C; 0 or 30 d) combinations, were cooked; texture, determined by a novel, variable-blade (VB) attachment, was compared with a widely-used Allo-Kramer shear (AK) attachment to determined its sensitivity in detecting variation in fillet texture. Instrumental texture was related to sensory measurements to determine attachments' accuracy in assessing cooked fillet texture. Weight of raw fillets decreased after 30-d frozen storage. Fillet weight further decreased after cooking. Moisture content decreased while fat content remained constant. The AK attachment detected differences in energy of shear, which decreased after 30-d …
