Latent Dimensions Between Water Use And Socio-Economic Development: A Global Exploratory Statistical Analysis, Edson Elídio Balata, Hugo Pinto, Manuela Moreira Da Silva

Regional Sustainability

Water use and socio-economic development are interconnected in complex ways. Causalities are not easy to identify but it is evident that a nexus between water use and socio-economic development does exist. Considering the diversity of national situations relating to these interrelated phenomena, its study should be considered from a global perspective. This article critically reviews the literature and information from official sources on the relevance of water use and circular economy in order to create a global picture, linking water with socio-economic development. Data from 195 countries were analyzed statistically. A factor analysis defined five essential latent dimensions on the …


Hydrologic Modeling With Remote Sensing For The Estimation Of Groundwater Resources Within The Sand River Catchment, South Africa, Sophia Bakar 2022 Duquesne University

Hydrologic Modeling With Remote Sensing For The Estimation Of Groundwater Resources Within The Sand River Catchment, South Africa, Sophia Bakar

Electronic Theses and Dissertations

The Sand River Catchment is an important tributary of the transboundary Limpopo River in South Africa, which spans Botswana, Mozambique, South Africa, and Mozambique. Groundwater is a critical resource in the region, especially in the context of population growth and climate change. Data are needed for proper management of these water resources. In regions where groundwater data are sparse in time, space, or both, the most promising solutions come from satellites and hydrologic models. Regional literature suggests that the Soutpansberg Mountains, located within the Sand Catchment, are high-elevation water towers with uncertain groundwater resources. Improved understanding of groundwater resources in …

Decreasing Trash In Local Creeks: A Program Evaluation Of The City Of San Jose’S Direct Discharge Trash Control Program, Lakeisha Bryant

Master's Projects

The entire San Francisco Bay was once a navigable waterway in the 1850s during the Gold Rush era. Large amounts of sediment from upstream erosion and mining flowed to the bay resulting in the downsizing of the bay’s square miles (Environmental Protection Agency, 2022). As a result of intense development on the bay shores and adjacent lands, the bay faces several challenges that affect its water quality and threatens aquatic ecosystems. Pesticides, mercury, metals, and pathogens are just a few substances in the bay that cause unhealthy conditions for aquatic life and threaten human health. California’s Water Resources Control Board …

Sturgeon Chub Distributional Patterns And Habitat Use And Benthic Fish Assemblage Structure In Missouri River Tributaries Of South Dakota, Mitchell R. Magruder

Dissertations & Theses in Natural Resources

Native species of the Missouri River drainage inhabiting benthic habitats dominate state and federal lists of species at risk. Sicklefin Chub Macrhybopsis meeki and Sturgeon Chub Macrhybopsis gelida are two native Missouri River benthic minnows that are currently under review for federal listing under the Endangered Species Act (ESA) due to extensive population declines and local extirpations within their native range. Substantial alterations to the Missouri River threaten Macrhybopsis spp. and other benthic fishes; however, large, less impacted tributaries in South Dakota may act as refugia for native species. The extent of Sicklefin Chub and Sturgeon Chub populations is largely …

Human And Hydrologic Influences On Nebraska's Endangered Rainwater Basin Wetlands, Sarah Thompson 2022 University of Nebraska-Lincoln

Human And Hydrologic Influences On Nebraska's Endangered Rainwater Basin Wetlands, Sarah Thompson

Dissertations & Theses in Earth and Atmospheric Sciences

Over half of wetlands in North America have been lost or degraded. Rainwater Basin (RWB) wetlands, located in south-central Nebraska, are a primary example of such loss; an estimated 90% have been destroyed by land conversion for agriculture. Remaining RWB wetlands are often embedded in row-crop fields, where they are threatened by altered surface water runoff flow, drainage features, and excess sediment inputs. Efforts at the state and federal level have been made to preserve this wetland complex due to the critical stopover habitat these wetlands provide for migratory birds. Land managers work to maintain sufficient water levels during migratory …

Hydrogeologic Investigation Of A Covered Karst Terrain, Joseph Peter Honings 2022 Louisiana State University at Baton Rouge

Hydrogeologic Investigation Of A Covered Karst Terrain, Joseph Peter Honings

LSU Doctoral Dissertations

Increasing demand for water for agricultural use within the Dougherty Plain of the Southeastern United States has depleted surface water bodies. In karstic landscapes, such as the Dougherty Plain in southwest Georgia where the linkages between surface and ground waters are close, there is a need to understand the physical characteristics of the subsurface that allow these close linkages. Having a better understanding of the subsurface characteristics will aid numerical modeling efforts that underpin policy decisions and economic analyses. Two common features on this karstic landscape are draws and geographically isolated wetlands. Using LiDAR, aerial imagery, and ground-penetrating radar, this …

Water: Arizona's Ticking Time Bomb, Bailey Wambold 2022 University of Washington, Tacoma

Water: Arizona's Ticking Time Bomb, Bailey Wambold

Access*: Interdisciplinary Journal of Student Research and Scholarship

For a landlocked state dominated by desert, Arizona has done an exceptional job supporting tremendous development and population growth with limited water resources. However, as climate change and anthropogenic environmental degradation further stress the region’s already-strained water resources, the future of Arizona’s still-growing populace hangs in the balance as current water policies and practices are proving inherently unsustainable. Despite an abundance of literature citing the consequences of a liberal attitude towards water in an arid climate, a myopic focus on promoting Arizona’s economic and political growth has resulted in the state’s modern need to adopt previously-unseen conservation measures in order …

Charting A Course To Conserve 30% Of Freshwaters By 2030, Sandra B. Zellmer 2022 William & Mary Law School

Charting A Course To Conserve 30% Of Freshwaters By 2030, Sandra B. Zellmer

William & Mary Law Review

One of President Biden’s earliest executive orders established an ambitious national goal to conserve at least 30 percent of U.S. lands, waters, and oceans by 2030. The Biden administration is not alone; over 100 countries support this goal as a means of combating climate change and slowing the pace of species extinction, both of which are accelerating at a rate that is unprecedented in history.

Despite its vow to pursue a wide-sweeping, all-of-government approach, Biden’s 30 by 30 initiative overlooks a critical component of the conservation goal—it pays virtually no attention to freshwater. Freshwater ecosystems are among the most endangered …


Landscape Change, Scale, And Human Response To Change In The Great Plains, Kate Bird 2022 University of Nebraska-Lincoln

Landscape Change, Scale, And Human Response To Change In The Great Plains, Kate Bird

Dissertations & Theses in Natural Resources

Great Plains landscapes are undergoing changes at multiple spatial and temporal scales due to processes ranging from woody encroachment to climate change. These changes may fundamentally alter the agroecosystems of the Great Plains such that the provisioning of ecosystem services including biodiversity and livestock production is affected. Improving our understanding of the effects of landscape change at multiple scales and how humans perceive and respond to these changes is important for facilitating research and management that enhances the resilience of these agroecosystems. As such, I first applied discontinuity theory and graph theory to evaluate the functional connectivity of the Central …
