From Access To Excess: Agribusiness, Federal Water Programs, And The Historical Roots Of The California Water Crisis, Tracy Marie Neblina

UNLV Theses, Dissertations, Professional Papers, and Capstones

The purpose of this paper is to show the link between water use, land consolidation, agribusinesses, and the water crisis that California began to experience in 2011. In order to better understand the relationship between the growth of agribusiness in the state and the evolution of water policy, this paper explores the historical context of land policy, the growth of farming in the San Joaquin Valley, and the development of federally funded water projects in the Central Valley. Years of expanding farmland and use of surface and underground water with limited regulation played an important role in exacerbating California’s water …

Uncertainty Analysis Of The Performance Of A System Of Best Management Practices For Achieving Phosphorus Load Reduction To Surface Waters, Jason D.M. Igras

Electronic Thesis and Dissertation Repository

The repeated occurrence of Lake Erie’s harmful algal blooms suggests an inadequate phosphorus management system that results in excessive loads to the lake. In response, Canadian and United States’ governments have issued a new management objective, a 40% reduction in total and dissolved reactive phosphorus loads relative to 2008. To provide scientific evidence to guide managers toward achieving their management objective, we used the International Organization of Standardization (ISO) 31010 Bowtie Risk Analysis Tool to analyze the performance of the phosphorus management system. The effectiveness of agricultural best management practices (BMPs) and their adoption were combined into a Bayesian belief …

Sustainable Agriculture: How France Promotes Sustainability, Jordan Pulling

Honors Theses

High consumption lifestyles led to a rapid decline in natural resources. The daily gestures of the people of the world use a quantity massive resource and energy that cannot be replaced. Decision makers of the world are invited to consider what changes will be needed to focus about sustainable and sustainable practices if we want to continue living in the way which we have become accustomed to. The development of renewable energies was a first step towards total sustainable development. Recently, however, we have seen a new way to reduce negative impacts on the rights of the Earth: changes in …

From Empty Lot To Garden Plot: Urban Agriculture In Chula Vista, Jennifer E. Gutierrez

Undergraduate Honors Theses

This project is an exploration of how agriculture can be incorporated into the fabric of the city of Chula Vista, which has both uniquely urban and suburban areas. The proposal is to integrate agriculture as a design tool to reconnect to the city’s agricultural past and as a model for cities of the future. First, I discuss Chula Vista’s history and contemporary context, including demographics. I review the existing urban agriculture policies Chula Vista has and compare them to other cities in California. The second part of the project is concerned with how to choose and develop a site for …

Effects Of Agricultural Restoration Practices On Stream Health In The Shenandoah Valley, Virginia, Erin L. Thady

Senior Honors Projects, 2010-2019

The Shenandoah Valley encompasses some of the highest agricultural producing regions in Virginia, many of which are large contributors of nutrients and sediment. The Conservation Reserve Enhancement Program (CREP) assists landowners in the installation of riparian restoration projects in which cattle are fenced out or a riparian buffer is planted. We examined the temporal effects of riparian restoration and the impact of upstream landuse on water quality for eleven farms participating in the CREP program for various times (from 1 to 14 years). We hypothesized that the length of time that the CREP program has been established would have a …

Quantifying Soil Greenhouse Gas Emissions And Soil Carbon Storage To Determine Best Management Practices In Agroecosystems, Tyler Goeschel

Graduate College Dissertations and Theses

Intensive agriculture, coupled with an increase in nitrogen fertilizer use, has contributed significantly to the elevation of atmospheric greenhouse gases (GHGs), including carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O). Rising GHG emissions usually mean a decrease in soil carbon. Currently, soil C is twice that of all standing crop biomass, making it an extremely important player in the C cycle. Fortunately, agricultural management practices have the potential to reduce agricultural GHG emissions whilst increasing soil C. Management practices that impact GHG emissions and soil C include various tillage practices, different N fertilization amounts and treatments (synthetic N, cattle …

Global And Regional Assessments Of Unsustainable Groundwater Use In Irrigated Agriculture, Danielle S. Grogan

Doctoral Dissertations

Groundwater is an essential input to agriculture world-wide, but it is clear that current rates of groundwater use are unsustainable in the long term. This dissertation assesses both current use of groundwater for country- to global-scale agriculture, and looks at the future of groundwater. The focus is on 1) quantifying food directly produced as a result of groundwater use across spatially-varying agricultural systems, 2) projecting future groundwater demands with consideration of climate change and human decision-making, and 3) understanding the system dynamics of groundwater re-use through surface water systems. All three are addressed using a process-based model designed to simulate …

The Golden Pandemic, Leo Dylan Stevens-Lubin

Senior Projects Spring 2016

The work in my senior show is a representation on how I feel about conventional focusing specifically on corn. The reason that I have chosen corn is because it is one of the most detrimental crops that we are growing in the US. It is grown specifically for livestock feed and ethanol with a minimal fraction for direct human consumption. Corn itself offers minimal nutritional benefits in comparison to most other vegetable crops and the overproduction of corn crops decreases the benefits all the more.
