The most frequently used frames throughout the dataset were “policy and government” and “water conscious,” and the sources most frequently utilized for information about …

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 …

Policies and programs have been utilized throughout the United States (U.S.) to reduce water use as a strategy to ensure sufficient water supplies for future demand. As governmental leaders and policy makers face increasing freshwater scarcity and supply unpredictability, along with rising costs and decreased federal funding, Best Practices (BPs) in water conservation are increasingly important to facilitate decision-making in choosing which strategies to employ. This project uses policy analysis to review and summarize various BPs, referencing both academic and professional literature. National fixture efficiency standards enacted in 1992 are credited as among the leading factors reducing indoor water use …

An Economic Assessment Of The Impacts Of Outdoor Water Use Restrictions In South Florida, Lara Kiesau

FIU Electronic Theses and Dissertations

Population growth and climate change are important factors determining residential water demand. Most residential water consumption can be attributed to outdoor use. To reduce water consumption, outdoor water use restrictions (OWRs) have become a popular policy tool in the last decades. We developed an integrated framework consisting of a Difference in Differences (DID) analysis, Value Function approach and Discrete Choice Model to perform an economic assessment of the impacts of OWRs in South Florida. The results reveal a decreasing effect of up to 133 gallons per person per month due to the strictest OWR, equaling a yearly value of almost …

Intercropping For Water Conservation: Environmental And Economic Implications Of A Sustainable Farming Practice In California's Central Valley, Sophie Baker

Scripps Senior Theses

California’s agricultural sector is the biggest water consumer in the state and faces intense pressure to reduce its overall water usage. Industrialized monoculture systems dominate the industry and often disregard long-term environmental and economic externalities for short-term profit maximization. To maintain longstanding food security and economic stability as well as protect the state’s water supply, it is critical that these systems transition to more sustainable and resilient production mechanisms. As an alternative to monoculture, intercropping affords greater potential to conserve water, protect soil quality, and increase crop yields, among other metrics of sustainability. However, there has been much controversy over …

Cost Effectiveness Of Greenhouse Gas Reductions Through Afforestation Of Agricultural Land In The Arkansas Delta, Karli A. Moore

Graduate Theses and Dissertations

Sequestration of atmospheric carbon in forested lands offsets carbon emissions from other industries. Conversion of private lands, particularly agricultural tracts in marginal areas, to forests can bolster carbon abatement. The United States government agencies administer some voluntary, incentive-based programs to encourage landowners to adopt production practices with positive environmental outcomes. This policy stream can be used to increase transition of marginal agricultural land to forests, thereby creating new carbon sinks. We analyze an eleven-county study area in the Arkansas Delta to determine feasibility for a subsidy focused on carbon abatement through afforestation. This study area is significant for two reasons: …

The intent of this study is to compare four California water agencies that have been designated as sustainable groundwater agencies (GSA), and determine what current programs and/or practices those agencies are using to meet the mandated requirements of the Sustainable Groundwater Management Act of 2014 (Act …

Changing Tides In Water Management: Policy Options To Encourage Greater Recycling Of Fracking Wastewater, Romany M. Webb

William & Mary Environmental Law and Policy Review

The U.S. has recently experienced a domestic energy renaissance, made possible by technological advances, enabling the development of unconventional oil and gas resources. Vital to this development is hydraulic fracturing (“fracking”), whereby fluid is injected underground at high pressure to fracture the rock, thereby enabling the flow of oil and gas. Fracking has recently faced growing opposition with many concerned about its environmental impacts, particularly its potential to adversely affect water resources, because fracking uses vast amounts of fresh water that ends up as contaminated wastewater. Most of this wastewater is disposed of through underground injection, resulting in its permanent …

Finding Water Scarcity Amid Abundance Using Human–Natural System Models, William K. Jaeger, Adell Amos, Daniel P. Bigelow, Heejun Chang, David R.

Geography Faculty Publications and Presentations

Water scarcity afflicts societies worldwide. Anticipating water shortages is vital because of water’s indispensable role in social-ecological systems. But the challenge is daunting due to heterogeneity, feedbacks, and water’s spatial-temporal sequencing throughout such systems. Regional system models with sufficient detail can help address this challenge. In our study, a detailed coupled human–natural system model of one such region identifies how climate change and socioeconomic growth will alter the availability and use of water in coming decades. Results demonstrate how water scarcity varies greatly across small distances and brief time periods, even in basins where water may be relatively abundant overall. …

Multi-Scaled Approaches For Protecting Montana's Watersheds And Water Resources, Elizabeth Yoder

Graduate Student Portfolios, Professional Papers, and Capstone Projects

The central theme carried among my four portfolio pieces is: using scientific and governmental approaches to conserve watershed health. For the purposes of this portfolio, I define watershed health as a very general term that describes the state of water quantity and quality that is available for human and ecosystem needs in a watershed. I see each of my portfolio pieces focusing on a different scale and method (i.e., science or government, including different levels of government, local, state and federal) for conserving watershed health. My first portfolio piece reviews water quality degradation caused by pharmaceuticals and personal care products …

Feasibility, Safety, Economic And Environmental Implications Of Whey-Recovered Water For Cleaning-In Place Systems: A Case Study On Water Conservation For The Dairy Industry, Yulie E. Meneses-GonzáLez

Department of Food Science and Technology: Dissertations, Theses, and Student Research

Several countries around the world are facing the challenge of producing food with limited water resources for a growing population. This reality is forcing all sectors involved in the food supply chain to look for water conservation strategies that contribute to assure global food security. Besides water consumption, the food industry has to deal with wastewater generation; therefore, water reconditioning and reuse is an attractive solution to address both issues. The goal of this research was to demonstrate that high quality water can be recovered from whey, a by-product of the cheese making process, and reused in cleaning-in place (CIP) …

Stressors And Strategies For Managing Urban Water Scarcity: Perspectives From The Field, Vivek Shandas, Rosa Lehman, Kelli L. Larson, Jeremy Bunn, Heejun Chang

Urban Studies and Planning Faculty Publications and Presentations

Largely because water resource planning in the U.S. has been separated from land-use planning, opportunities for explicitly linking planning policies to water availability remain unexamined. The pressing need for better coordination between land-use planning and water management is amplified by changes in the global climate, which will place even greater importance on managing water supplies and demands than in the past. By surveying land and water managers in two urbanizing regions of the western United States—Portland, Oregon and Phoenix Arizona—we assessed the extent to which their perspectives regarding municipal water resource management align or differ. We specifically focus on characterizing …

Due to stresses on the water supply in southern Nevada, which include an average of three million tourists per month and an ongoing drought since the year 2000, water conservation is imperative in order to sustain the growing urban area of Las Vegas. The purpose of this study is to assess water use in fourteen casinos on and off the Las Vegas Strip (the main boulevard of the largest casinos in Las Vegas) in order to suggest approaches for water conservation, such as reducing, reusing, and modifying the current system. Since data on water consumption is not publicly available, five …

Evaluating American Rainwater Harvesting Policy: A Case Study Of Three U.S. Cities, Russell J. Fricano, Alison Grass

Urban and Regional Studies Institute Publications

In spite of increasing support for rainwater harvesting by public agencies, environmental organizations and well-defined industry guidelines, the researchers found a strikingly limited number of municipalities with formal rainwater harvesting policies and programs. With literature on rainwater harvesting limited to mostly instructional material, the researchers were compelled to examine the feasibility of rainwater harvesting guidelines and practices. International and domestic rainwater harvesting guidelines were considered. The researchers surveyed municipalities which have implemented rainwater harvesting policies and ordinances to determine the extent to which industry prescribed guidelines are feasible. The subject jurisdictions commonly regulated rainwater harvesting through ancillary city codes or …
