To Know The Land With Hands And Minds: Negotiating Agricultural Knowledge In Late-Nineteenth-Century New England And Westphalia, Justus Hillebrand
To Know The Land With Hands And Minds: Negotiating Agricultural Knowledge In Late-Nineteenth-Century New England And Westphalia, Justus Hillebrand
Electronic Theses and Dissertations
Ever since the eighteenth century, experts have tried to tell farmers how to farm. The agricultural enlightenment in Europe marked the beginning of a long arc of new experts aiming to change agricultural knowledge and practice. This dissertation analyzes the pivotal period in the late nineteenth and early twentieth century in Germany and the United States when scientists, improvers, and market agents began to develop comprehensive ways to communicate agricultural innovation to farmers. In a functional approach to analyzing the negotiation of agricultural knowledge through its communication in things, words, and practices, this dissertation argues that the process of change …
Economics Of Managing Loblolly Pine Plantations For Increased Wildlife Biodiversity, Melissa Griffith
Economics Of Managing Loblolly Pine Plantations For Increased Wildlife Biodiversity, Melissa Griffith
Electronic Theses and Dissertations
The goal of this thesis was to identify the differences between the costs incurred and revenues gained from managing loblolly pine (Pinus taeda) plantations in East Texas for strictly timber production or a combination of timber production and wildlife biodiversity. Management regimes evaluated had varying planting densities, thinning frequency and intensities, prescribed burn intervals, and site indices. Economic analyses used to evaluate management regimes over a range of nonindustrial private landowner (NIPF) alternative rates of return (ARRs) and site indexes were net present worth, land expectation value, and equal annual annuity. These economic analyses demonstrated that altering management …
Geophysical Delineation Of Megaporosity And Fluid Migration Pathways For Geohazard Characterization Within The Delaware Basin, Culberson County, Texas, Jonathan David Woodard
Geophysical Delineation Of Megaporosity And Fluid Migration Pathways For Geohazard Characterization Within The Delaware Basin, Culberson County, Texas, Jonathan David Woodard
Electronic Theses and Dissertations
ABSTRACT
Differential dissolution of gypsum karst within the Delaware Basin poses a significant threat to infrastructure that society depends on. The study area is located in Culberson County, Texas and traverses a distance of approximately 54 kilometers along RM 652 within the Gypsum Plain which is situated on the northern margin of the Chihuahua Desert and includes outcrops of Castile and Rustler strata that host karst geohazards. Regions of karst geohazard potential have been physically surveyed proximal to the study area in evaporites throughout the Castile Formation outcrop; minimal hazards, in comparison to the Castile Formation, have been documented in …
Spatiotemporal Analyses Of Recycled Water Production, Jana E. Archer
Spatiotemporal Analyses Of Recycled Water Production, Jana E. Archer
Electronic Theses and Dissertations
Increased demands on water supplies caused by population expansion, saltwater intrusion, and drought have led to water shortages which may be addressed by use of recycled water as recycled water products. Study I investigated recycled water production in Florida and California during 2009 to detect gaps in distribution and identify areas for expansion. Gaps were detected along the panhandle and Miami, Florida, as well as the northern and southwestern regions in California. Study II examined gaps in distribution, identified temporal change, and located areas for expansion for Florida in 2009 and 2015. Production increased in the northern and southern regions …
Social Ecological Food Systems: Sustainability Lessons From Maine Dairy Networks, Julia B. Mcguire
Social Ecological Food Systems: Sustainability Lessons From Maine Dairy Networks, Julia B. Mcguire
Electronic Theses and Dissertations
Milk production has played an integral role in the culture, landscape, and economy of Maine’s agriculture. Maine dairy farmers have faced numerous sustainability challenges to economic, environmental, and social aspects of their industry. Like many other complex social ecological systems, the Maine dairy industry faces a gap between scientific knowledge and actionable management or policy. A cultural dichotomy exists between conventional and organic farming. Shifting the focus from this binary, metrics such as social capital may play a key role in solving sustainability issues. Difficulties arise in the governance of complex social ecological systems when the scales of assessment, management, …
Sharing A Landscape: The Construction Of Sense Of Place On The Maine Coast, Andrea Jane Ednie
Sharing A Landscape: The Construction Of Sense Of Place On The Maine Coast, Andrea Jane Ednie
Electronic Theses and Dissertations
Motivated by interest and concern over the changing coastline in Maine, this study uses the concept of sense of place to develop an understanding of how a range of users share the resource, and to explore how place meanings are associated with their social experiences and perceptions. The site for this study was the Stonington region archipelago, an area that has not yet experienced the same amount of development as seen on the southern Maine coast, yet one that has witnessed a boom in recreational use and an influx of people from other areas. Using a mixed methodology, two groups …
Economic Approaches To Public And Private Land Conservation In The United States, Amy Claire Hudnor
Economic Approaches To Public And Private Land Conservation In The United States, Amy Claire Hudnor
Electronic Theses and Dissertations
This research is composed of two essays, both using economic approaches to evaluate land conservation in the United States. Essay I uses econometric methods to evaluate public lands, and Essay II uses New Institutional Economics to gain insight into private land conservation. Essay I is titled "The Relationship Between Public Conservation Lands and Tourism Employment in the United States." This research examines the relationship between public conservation lands and the importance of tourism in United States counties. A spatial error model is used on three categories of conservation land: general public land, recreational land, and wilderness areas. A positive, significant …
An Engineering, Economic, And Political Approach To Beach Erosion Mitigation And Harbor Development: A Review Of The Beach Communities Of Camp Ellis, Maine, Wells, Maine, And Cape May, New Jersey, Edmund Cervone
Electronic Theses and Dissertations
The history of coastal engineering projects is fraught with problems. In this thesis I examine the federal navigation project at Wells, Maine. In Wells, an incomplete understanding of the coastal setting led to a faulty engineering design responsible for a poorly functioning inlet and harbor and damage to neighboring beaches and wildlife habitat. Project planners and designers did not account for all unforeseen problems that arose. Reviewing the history of Wells Harbor demonstrates how proper attention to the natural setting, economics, and the political environment is essential to a successful project and enables agencies and stakeholders better to address contingencies …
