Biodynamic Agriculture: A Valuable Alternative To The Industrial Farming System, Eden K. Olsen
Biodynamic Agriculture: A Valuable Alternative To The Industrial Farming System, Eden K. Olsen
Scripps Senior Theses
Since the Scientific and Industrial revolutions, advancing technologies and cutting-edge science have enabled our society to continually promote a growing global economy. Industrial growth has increasingly become a top priority for most governments, notably in the agricultural realm. The advances towards agricultural industrialization began in the 17th century and escalated during the Green Revolution, which examined the possibility of using synthetic fertilizers and mechanization in farming to decrease labor and improve yields. Although seen as economically beneficial, the shift from an agrarian lifestyle to industrial farming has created an ecological, economic, and ideological crisis to our modern world. This …
Urban Farm And Community Garden Hybrid Models: A Case Study Of The Huerta Del Valle Community Garden, Leah Hochberg
Urban Farm And Community Garden Hybrid Models: A Case Study Of The Huerta Del Valle Community Garden, Leah Hochberg
Scripps Senior Theses
This study examines models of community gardens and urban farms and determined a successful hybrid model for future implementation at the Huerta del Valle Community Garden. This was accomplished through analyzing the unique benefits and drawbacks of community gardens and urban farms as defined by the author, and then determining the components of each model that would maximize Huerta del Valle’s social and economic potential. Community gardens are defined in this thesis as places where community members can grow their own food in individual plots, and these spaces often contribute to community building, hands-on gardening education, and improved food access. …

Impacts And Feasibility Of The Us And The Eu Sustainability Criteria On Existing Land-Use Practices, Krissana Treesilvattanakul
Open Access Dissertations
Several studies have examined the land use and economic consequences of national and multi-national biofuel policies. They explored the impacts of biofuels mandates mainly based on the quantitative biofuel targets. However, the recently updated renewable policies of the United States and the European Union, which are the US Renewable Fuel Standard (RFS) and EU Directive 2009/28 of the Renewable Energy Directive (RED) both place restrictions on land that can be used to produce biofuel, and these restrictions are generally known as sustainability criteria. This research aims to determine to what extent sustainability criteria are actually binding; that is, would they …
The Effect Of Mulch Type And Thickness On The Soil Surface Evaporation Rate, Michael Mcmillen
The Effect Of Mulch Type And Thickness On The Soil Surface Evaporation Rate, Michael Mcmillen
Horticulture and Crop Science
There is a continual drive to conserve water and improve irrigation efficiency in agriculture, especially in regions where water resources are limited and regulated. Mulching is one cultural practice which can be used to reduce water needs. Using certain agricultural byproducts as mulch is a sustainable practice which can provide other benefits as well such as improving soil. Wheat straw, grass clippings, and leaf debris are fairly abundant byproducts which can be used as mulch. An experiment was conducted to determine which of these readily available mulching materials would be best at conserving soil moisture, and at which thicknesses, 5, …
Analyzing Healthy, Local Food Systems: A Case Study Of Owensboro, Kentucky, Callie Hayden
Analyzing Healthy, Local Food Systems: A Case Study Of Owensboro, Kentucky, Callie Hayden
Theses and Dissertations--Community & Leadership Development
Across the US, support is ever-growing for the local food movement. This growing trend promotes food security, supports farming families, ensures universal access to safe and healthy food products, enhances local economies, and encourages environmental and social well-being. People around the US are implementing sustainable local food systems as a means of meeting their individual community’s needs. While this movement is being popularized dramatically around the world, many cities and regions have yet to address it. This study reviews the existing literature on local food system models in an effort to answer the research question: What are the “ingredients” of …
Energy In The Corn Belt: Is Maize Production Sustainable?, Matthew Bernau
Energy In The Corn Belt: Is Maize Production Sustainable?, Matthew Bernau
Electronic Theses and Dissertations
Technological and scientific innovation has transformed agricultural production. Corn production methods changed from a sustainable, nutrient recycling production system to one reliant on imported fossil energy inputs. Located in the Western Corn Belt, Union County, South Dakota was chosen as the study area. Changes in production methods are represented by four technological epochs: 1) The Draft Horse Epoch, 1890-1920; 2) The Tractor Epoch, 1920-1950; 3) The Fertilizer Epoch, 1950-1980; and 4) The Biotechnology and Precision Agriculture Epoch, 1980-2010. The energy budget method was used to measure the energy sustainability of corn production. The findings show that the volume of corn …
Evaluating The Sustainability Of Four Organic Vegetable Production Systems, Delia W. Scott
Evaluating The Sustainability Of Four Organic Vegetable Production Systems, Delia W. Scott
Theses and Dissertations--Plant and Soil Sciences
A field study evaluating the sustainability of four organic vegetable production systems was conducted in Lexington, Kentucky in 2006 and 2007. The four systems included no-till, raised beds covered with biodegradable black mulch, bare ground with shallow cultivation, and bare ground with shallow cultivation and wood chip mulch. The two-year study compared yield, weed control, labor, and costs associated with each system, as well as physical, chemical, and microbiological soil characteristics. In 2006, tomatoes (Lycopersicon esculentum Mill.) were grown in the four systems, with no significant difference in yield. Summer squash (Cucurbita pepo L.) was grown in the …
Impacts Of Agricultural Disturbance On Communities Of Selected Soil Fungi (Agaricomycetes), Jessie R. Wong
Impacts Of Agricultural Disturbance On Communities Of Selected Soil Fungi (Agaricomycetes), Jessie R. Wong
Electronic Thesis and Dissertation Repository
The objective of this study was to use phylogeny-based and community-based analyses to compare the community composition of Agaricomycetes among four different agricultural treatments at the Kellogg Biological Station Long Term Ecological Research (KBS LTER) site. A phylogenetic tree that included 591 ribosomal DNA sequences previously obtained from KBS LTER documented the composition of Agaricomycete communities in each treatment. Sequences from KBS LTER were placed into 472 OTUs (putatively species-level operational taxonomic units defined by 99% or greater sequence similarity) and these were dominated by the Agaricales (with 330 OTUs), Cantharellales (39 OTUs), Hymenochaetales (29 OTUs), and Polyporales (23 OTUs). …

A Baseline Study Of Biofuel Feedstock Growth On Non-Traditional Agronomic Land In Utah, Dallas A. Hanks
A Baseline Study Of Biofuel Feedstock Growth On Non-Traditional Agronomic Land In Utah, Dallas A. Hanks
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Nearly all highway, airport, and military areas in Utah cost money to maintain and are often safe harbor for noxious weeds and pests. This project hypothesized that money could be saved and biofuel feedstocks could be grown in these areas, improving sustainability. Agronomic conditions and growth methods were tested to determine if biofuel feedstock production could occur on these marginal, non-traditional plots of land. Models developed illustrate that maintenance costs for these areas can be nullified if oilseed crops grown yield 600 pounds/acre and are used for biodiesel production. This feedstock yield would result in approximately 25 gallons of biodiesel …
Farmers Motivations To Practice Sustainable Agriculture, Kimberly A. Floeser
Farmers Motivations To Practice Sustainable Agriculture, Kimberly A. Floeser
Honors Theses
An increasing awareness of human and environmental health issues and the destruction of family farms and rural communities have caused a significant change in the way many farmers, consumers, and policy‐makers are thinking about and relating to food, the results of which can be seen largely in the growth of the organic and sustainable food industry. This paper attempts to examine and explain farmers’ attitudes towards sustainable agriculture, and their motivations to use sustainable methods of production. A survey was distributed to 533 farms that are members of the Northeast Organic Food Association of New York (NOFA‐NY). The data obtained …

Nerica, Kimaa, And The Sustainability Of Rice Farming In Magbainba Ndohahun Chiefdom, Sierre Leone: An Anthropological Perspective, Christopher M. Thomas
Global Honors Theses
With the looming threat of a world food shortage, it has become increasingly important for developing African countries to strengthen their indigenous farming practices. This thesis examines the system of rice farming within Sierra Leone’s rural Magbainba Ndohahun Chiefdom, which the author visited in 2008 as part of a University of Washington interdisciplinary program on rice farming methods. Practices related to fallowing, fertilization, hired labor, and land tenure (kimaa) are discussed and placed within the context of long-term sustainability.
