Drinking Water Governance For Whom? An Institutional Analysis Of Rural Drinking Water Systems In New Mexico, Tucker Colvin

Geography ETDs

Rural community drinking water systems in New Mexico are facing many challenges, including a lack of personnel, deteriorating infrastructure, lack of funds, overly burdensome and confusing regulation, environmental concerns, and concerns over water rights. Governing agencies are creating vulnerability by making managers prioritize some issues and neglect others. Water systems designated a Mutual Domestic Water Consumers Associations are especially problematic because they are small and managed by volunteers but have as much regulatory burden as larger municipalities. I use the theory of institutional work to explain how an institution that was originally designed to help low-income and rural communities is …

Analyzing Climate Risk To Maritime Cypress Swamps And Pine Savannas Of The Gulf Of Mexico Coastal Plain, Clay Stephens Tucker

LSU Doctoral Dissertations

As sea levels rise, coastal trees are increasingly stressed by saltwater inundation, and stressed trees are ideal for studying changes in the environment through time. Dendrochronology has been used for more than a century to explain changes in past environments using tree rings. Using ring widths and stable isotopes from coastal trees, the effects of tropical cyclones and freshwater moisture availability are shown in regard to tree growth and ultimately are discussed in terms of change to the environment as a whole. Changes in tree growth as they relate to various climate parameters are measured using superposed epoch analysis, moving-window …

Automatic Features Extraction From Time Series Of Passive Microwave Images For Snowmelt Detection Using Deep-Learning – A Bidirectional Long-Short Term Memory Autoencoder (Bi-Lstm-Ae) Approach., Bienvenu Sedin Massamba

LSU Master's Theses

The Antarctic surface snowmelt is prone to the polar climate and is common in its coastal regions. With about 90 percent of the planet's glaciers, if all of the Antarctica glaciers melted, sea levels will rise about 58 meters around the planet. The development of an effective automated ice-sheet snowmelt monitoring system is therefore crucial.

Microwave remote sensing instruments, on the one hand, are very sensitive to snowmelt and can see day and night through clouds, allowing us to distinguish melting from dry snow and to better understand when, where, and for how long melting has taken place. On the …

An Atmospheric And Spatiotemporal Examination Of Lightning-Initiated Terrestrial Gamma-Ray Flashes Detected By The Fermi Satellite And Tetra Ii, Deirdre Colleen Smith

LSU Doctoral Dissertations

Terrestrial Gamma-ray Flashes (TGFs) are sub-millisecond bursts of the highest naturally occurring light-energy found within Earth’s atmosphere. TGFs are associated with the electric fields produced in thunderstorms and are geolocated by coincident sferics from lightning strokes. Though billions of lightning strokes occur globally each year, fewer than 1,000 TGFs are detected via satellite and ground-based sensors and only a small fraction are geolocated via sferics.

To date, few studies have focused on individual thunderstorms and climates that produce TGFs. This dissertation examines TGFs from two differing data samples: 1) NASA's Fermi Gamma-Ray Burst Monitor (2013-2018) and 2) The TGF and …

Dry-Land Farming, Jerry L. Williams

Homestead Geography Project - Oral Histories and Publications

Dry-land farming is a system of land use, crop management, and timing of operations that are designed to cope with the conditions of climate and rainfall of a semiarid land. Experiments began on dry-land techniques as early as the 1860s and the methods became well-known in the Great Plains by the end of the 1880s. A major component of dry farming, which is a term (along with dry-land farming) of western American origin, is the conservation of soil moisture during dry weather by special methods of tillage and plant adaptation. It is not farming without moisture, but farming where moisture …

Reasons For Vacating The Land, Jerry L. Williams

Homestead Geography Project - Oral Histories and Publications

According to interview data, the mid droughts began very early. The first was in 1908 and 1909 followed by a low rainfall period of 1910 and 1911. These mild droughts were followed by another dry period in 1925 and 1926 and later by the dust bowl period of the mid-1930s. To experience even a mild drought was sufficient to weed out the land speculators who had little interest in farming the land. There were also a number of people who intended to farm, but arrived with insufficient funds to purchase the necessary equipment to produce enough surplus to ride through …

Subdividing The Public Lands: The Apportionment And Settlement Of Northeast New Mexico, Jerry L. Williams

Homestead Geography Project - Oral Histories and Publications

The land of northeastern New Mexico, outside of the recognized title rights of the former Mexican citizens, became the public domain of the United States by the treaty of Guadalupe Hidalgo in 1848. This immediately allowed for US control over 10,000 square miles of land within the area east of the 105° meridian and north of a line roughly defined by Interstate 40 in Quay County and the boundary between San Miguel and Guadalupe counties. Portions of the northeast which were excluded from this public domain by the action of the Court of Private Land Claims between 1891 and 1904 …

Peopling The Northeast Plains, Jerry L. Williams

Homestead Geography Project - Oral Histories and Publications

During the 1880s and the early part of the 1890s the cattle companies were continuing to hire ranch hands to prove up homesteads around water holes. At the same time the early farmers began to appear in the northeast, but not in the form of the sodbusters who were to later swarm over the highland llanos during the early part of the twentieth century. The early farmers were not labeled "nesters," which was the derogatory term coined by the stockmen for the people who turned small parcels of the grassland into fields and began erecting fences over the plains. The …

Natural Elements Of Northeastern New Mexico, Jerry L. Williams

Homestead Geography Project - Oral Histories and Publications

Northeastern New Mexico is one of the most diverse natural landscapes in the state. Large volcanic vents dot the basalt flows that cap the piedmont surface, providing a very rugged horizon rather than the flat monotonous topography usually associated with the Great Plains of the United States. The dissected and rolling plains are broken by severely eroded canyons that have cut through the sandstone layers topped with caliche. In some areas where the major drainages confluence (such as the intersection of the Ute and Canadian or the Conchas and the Canadian) the narrow canyons broaden into extensive valleys characterized by …

Missouri Avenue On The Caprock, Jerry L. Williams

Homestead Geography Project - Oral Histories and Publications

Lured by reports about grama grass that was so high it tickled the belly of a horse, the settlers poured onto the high plains of New Mexico during the first decade of the twentieth century. Boom towns began to sprout up along the sidings that the single-line railroads needed for intersecting trains and for locating maintenance crews. The towns especially blossomed if the siding was next to a highland area of prairie that appeared capable of dryland farming. The railroad companies, which were provided with large blocks of land to promote settlement, and the merchants of the new railroad towns …

Interviews With Pioneers, Jerry L. Williams

Homestead Geography Project - Oral Histories and Publications

There are many first-generation pioneers still living in northeastern New Mexico. Most are over eighty years of age and several are nearing the century mark. Their recall of the era of farming is remarkable and it is fascinating to record the events which are firmly locked into their minds. Many decades have passed since their families abandoned the farm and the homestead and either migrated to urban areas for employment or remained on the land by converting to a cattle economy. When probed or reminded of events through the line of questioning, most interviewees would discourse with clear details and …

Homesteading And Public Land Law, Jerry L. Williams

Homestead Geography Project - Oral Histories and Publications

It is important to the discussion of Butcher and Wyatt as homesteaders to understand the public land laws which affected their choice of land. Consequently, a review of the history of land legislation affecting the allocation and use of the public domain is in order and particularly that legislation under which Butcher and Wyatt made entry: the Homestead Act of 1862. Through this act early settlers around Tucumcari were able to acquire, at little expense, 160 acre tracts of land. In addition, the shortcomings and beneficial aspects of other acts of Congress concerning the acquisition of public domain will be …

Elements To Assist The Farmers And Promote Immigration, Jerry L. Williams

Homestead Geography Project - Oral Histories and Publications

The purpose of this portion of the resource survey of the northeastern plains is to reconstruct the settlement phase which occurred between 1880 and 1940, the period generally referred to as the homesteading era. To reconstruct the 60 years of human settlement and resettlement required an extensive review of secondary information resources as well as a field project(?) oriented around the collection of data from primary information resources. Much of the information that was compiled was directed toward a mapping project of the northeastern plains which included the location of the places named by the settlers as well as identifying …

Backyard Wildlife Refuges In Albuquerque, Nm: An Urban Land Ethic In Practice, Laurel E. Ladwig

Geography ETDs

In the urban setting, biodiversity conservation requires intentionally creating spaces humans and wildlife can share. An urban land ethic can guide this process. Developing and practicing this ethic requires asking questions that consider approaches from multiple disciplines and avoid anthropocentric framing. Both More-Than-Human and Critical Physical Geography bring multiple knowledges into conversation to make complex realities visible. This project explores these fields of scholarship as guides for reconciling the needs of the land community.

Sharing familiar spaces creates opportunities for developing ethical relationships between humans, non-humans, and natural systems. Wildlife gardening creates habitat in our residential and community areas, providing …

Unpacking The Process And Outcomes Of Ethical Markets: A Focus On Certified B Corporations, Renée Bogin Curtis

Dissertations and Theses

The growth in conscious consumption presents an opportunity to 1) better understand the potential outcomes of ethical market practices as a community-advocacy tool and 2) to consider potential policy considerations. The marketplace has increasingly become an arena for social action. This leads to the question of how can markets facilitate ethical business practices and community benefits? The recent rise of social benefit corporations warrants an evaluation of the outcomes of ethically-driven markets. Using a comparative research design and qualitative interview methods, this study examines certified Benefit Corporations (B Corps) in two selected cities: Philadelphia and Portland. Through interviews with B …

Learning Set Representations For Lwir In-Scene Atmospheric Compensation, Nicholas M. Westing, Kevin C. Gross, Brett J. Borghetti, Jacob A. Martin, Joseph Meola

Faculty Publications

Atmospheric compensation of long-wave infrared (LWIR) hyperspectral imagery is investigated in this article using set representations learned by a neural network. This approach relies on synthetic at-sensor radiance data derived from collected radiosondes and a diverse database of measured emissivity spectra sampled at a range of surface temperatures. The network loss function relies on LWIR radiative transfer equations to update model parameters. Atmospheric predictions are made on a set of diverse pixels extracted from the scene, without knowledge of blackbody pixels or pixel temperatures. The network architecture utilizes permutation-invariant layers to predict a set representation, similar to the work performed …
