Essays On The Economics Of Regional Development And Public Policy, Wai Yan Siu

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

My dissertation integrating theory and practice into fostering sustainable, ecofriendly, and equitable public policy that promote the well-being of generations to come. My main research questions are: how can we transform the complex socioeconomic systems to build future resilience? In the first chapter, I identify and quantify the effect of the presence of tight oil and gas extraction on the agricultural productivity. This study informs evidence-based policymaking on pressing environmental issues. In the next chapter, I studied the effectiveness of existing policy of urban growth control from an evolutionary landscape and found that the decades-old regulation does not fulfill its …

Space-Time Dynamics Of The Uinta Fremont Agricultural Transition In Eastern Utah And Northwestern Colorado, Trista N. Schiele

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Recent work in Utah’s northern Uinta Basin documents associations between variability in precipitation and fluctuating populations during the Fremont period, AD 300-1350. In this study, I evaluate the role that precipitation variability had on observed regional population density and settlement patterns. I test a model of village formation in Cub Creek, Utah across the larger Uinta Basin and its periphery by creating two predictive statistical models using archaeological data anchored in space and time. I conclude that while precipitation variability plays a role in the initial adoption of farming practices which itself leads to higher population densities, changes in patterns …

Subsistence Strategy Tradeoffs In Long-Term Population Stability Over The Past 6,000 Years, Darcy A. Bird

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

I conduct the first comparative analysis of long term human population stability in North America. Questions regarding population stability among animals and plants are fundamental to population ecology, yet no anthropological research has addressed human population stability. This is an important knowledge gap, because a species’ population stability can have implications for its risk of extinction and for the stability of the ecological community in which it lives. I use archaeological and paleoclimatological data to compare long term population stability with subsistence strategy and climate stability over 6,000 years. I conduct my analysis on a large scale to better understand …

The Value Of Farmland: Mapping Assessor Data To Understand Land Use Change, Lyndi Perry

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Ideas developed by regional economists have potential applications within the urban planning field. One potential application is toward conserving farmland, and within this thesis this topic is examined for the study area of Utah County, Utah. Using assessor data, a land value map is created and further used to develop a regional economic model and spatial models that were analyzed for patterns of land use change.

Findings show that representing land value as continuous surface maps is a useful approach. The maps reveal that Utah County has densified as its population increased while farmland loss still occurred in agriculturally-important areas. …

The Power Law Distribution Of Agricultural Land Size, Lauren Chamberlain

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This paper demonstrates that the distribution of county level agricultural land size in the United States is best described by a power-law distribution, a distribution that displays extremely heavy tails. This indicates that the majority of farmland exists in the upper tail. Our analysis indicates that the top 5% of agricultural counties account for about 25% of agricultural land between 1997-2012. The power-law distribution of farm size has important implications for the design of more efficient regional and national agricultural policies as counties close to the mean account for little of the cumulative distribution of total agricultural land. This has …

Assessment Of Potential Changes In Crop Yields In The Central United States Under Climate Change Regimes, Neil Matthews-Pennanen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Climate change is one of the great challenges facing agriculture in the 21^st century. The goal of this study was to produce projections of crop yields for the central United States in the 2030s, 2060s, and 2090s based on the relationship between weather and yield from historical crop yields from 1980 to 2010. These projections were made across 16 states in the US, from Louisiana in the south to Minnesota in the north. They include projections for maize, soybeans, cotton, spring wheat, and winter wheat.

Simulated weather variables based on three climate scenarios were used to project future crop …

Nutritional And Economic Analysis Of Small-Scale Agriculture In Imbabura, Ecuador, Jake Erickson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Intervention projects in the developing world normally aim to satisfy either the nutritional needs of a group, or advancing the economic stability, but not both. One of the many issues that may arise by narrowly focusing and creating an aid program is that although a group may be fed, they are not equipped to mitigate risks that will arise after project completion and thus continue or revert back to a malnourished state. A bridge is required to join the economic and nutritional programs to create aid interventions that are sustainable past the point of donor separation.

This paper proposes the …

The Influence Of Collective Action And Policy In The Development Of Local Food Systems, Lori Porreca

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The modern global agrifood system has had significant negative impacts on consumers and producers. This has precipitated the rise of local food systems that are purported to improve the health and livelihoods of consumers and producers. High expectations have led to significant public and private resources dedicated to the development of local food systems. Despite this, there has been little systematic research exploring the social and institutional conditions that facilitate or frustrate local food system development.

Using a comparative case study approach, this study explored the ways local structural conditions, collective action, food system policies, and the political context affect …

Random Forests Applied As A Soil Spatial Predictive Model In Arid Utah, Alexander Knell Stum

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Initial soil surveys are incomplete for large tracts of public land in the western USA. Digital soil mapping offers a quantitative approach as an alternative to traditional soil mapping. I sought to predict soil classes across an arid to semiarid watershed of western Utah by applying random forests (RF) and using environmental covariates derived from Landsat 7 Enhanced Thematic Mapper Plus (ETM+) and digital elevation models (DEM). Random forests are similar to classification and regression trees (CART). However, RF is doubly random. Many (e.g., 500) weak trees are grown (trained) independently because each tree is trained with a new randomly …

Nursery Production Of Selected Actinorhizal Species, Taun D. Beddes

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

An important aspect of sustainable landscaping includes utilization of plants requiring few to no inputs once installed. Limited research exists for many of these species. For this research, we chose four with potential for use: Mexican cliffrose (Purshia mexicana), silver buffaloberry (Shepherdia argentea), roundleaf buffaloberry (Shepherdia rotundifolia), and seaside alder (Alnus maritima). All are actinorhizal, meaning they form a symbiotic relationship with soil-borne Frankia bacteria that fix atmospheric N₂ for plant use. Many actinorhizal species are also native to arid environments where soils have low organic matter (OM) content. We suspect …

Agroforestry Practice Adoption Among Solomon Island Women On The Island Of Malaita, Etta K. Sechrest

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The goal of agricultural training is the adoption and diffusion of introduced agriculture techniques. New subsistence agricultural techniques have been introduced mainly to the male population in many developing countries, even though most subsistence farmers are women. Therefore, an understanding of how new subsistence agricultural techniques can be introduced and adopted by women would be important to achieve. This study focuses on women's adoption of agricultural techniques. It takes place on the island of Malaita, in the Solomon Islands. The study looks at the adoption of agroforestry and several other subsistence techniques that were introduced under a joint program by …

Treatment Of Saltcedar (Tamarix Spp.): Economics And Feasibility, Christopher L. Thompson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The invasive species Saltcedar is affecting water and land resources throughout the western states of America. Because of great water use capabilities and other ecosystem detriments, Saltcedar has been targeted for treatment.

For successful management of Saltcedar, individual landowners need to be aware of the costs and benefits of treating Saltcedar. Eleven of the most commonly reported treatment methods were evaluated for firm level economic feasibility. Evaluated on the basis of treatment cost, treatment effectiveness, Saltcedar water-use, and re-vegetation water-use, a production plan of ten years was created for each treatment method. Some treatment methods required re-treatment and were evaluated …

The Value Of Microcomputers In Agriculture, John P. Gibney

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this paper was two-fold. To examine the hardware and software purchased, training taken, and benefit recieved by farmers recently purchasing micro computers and to demonstrate a systematic approach of evaluating software. Over five hundred farmers that use microcomputers were surveyed on farm size and type, personal and computer system characteristics, and perceived benefit from the computer. Farmers that use computers were found to be younger, have higher incomes and benefit more from their computer systems with time than averages for all farmers. The use of printers and/or modems appeared to be justified for all levels of income. …

Economic Impacts Of Water Conservation Measures In Agriculture And Energy Within The Upper Colorado River Basin, Douglas R. Franklin

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The demand for water is increasing in the western United States. Coupled with growing emphasis on development of the western resources, the limited supply of water will create an expanding competitive market for water by agricultural, energy, industrial and municipal users.

The Upper Colorado River Basin is faced with a question of what water conservation measures in the agricultural and energy sectors can be instigated without reducing agricultural output. If the decision is made to adopt water conservation technology measures, this study addresses the impacts in the private and public investment sectors under alternative public policies, i.e., regulation or non-regulation …

The Impact Of The Prototype Oil Shale Development On Agricultural And Municipal Water Supplies In The Uintah Basin, Roger Orson Tew

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In this paper the institutional factors affecting water distribution in the Upper Colorado River Basin in general and the Uintah Basin are presented. The historical development of the appropriation doctrine of water allocation is outlined and Utah water policy is examined. These institutional factors are analyzed in light of the prototype oil shale development in the Uintah Basin and potential impact on the area's agricultural sector. Oil shale water estimates are compared with Uintah Basin water availability and examined with regard to population projections and municipal water use. Lastly, Utah water policy and the appropriation doctrine are viewed as restraints …

Changes In Agricultural Production And Cash Farm Income In Cache County, Utah, 1909-1949, Lavon S. Fife

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

During the period 1909-1949 many changes took place in agricultural production and cash farm income in Cache County, Utah. Important factors which caused changes in agricultural production and cash farm income during this period were technological developments in farm power and machinery, plant and animal breeding, changes in consumer demands price changes, and climatic conditions. The influence of these factors on both production and income varied with the enterprise, the commodity, and the year studied.
