Ex-Ante Cost-Benefit Analysis Of High-End And Low-Cost Wireless Sensor Network (Wsn) Technology Packages For Efficient Irrigation Water Management In The Philippines, Marielle Q. Aringo, Victor B. Ella, Camille G. Martinez, Gamiello S. Pereira

Journal of Economics, Management and Agricultural Development

Four wireless sensor network (WSN) technology packages developed for efficient irrigation water management in the Philippines were subjected to ex-ante cost-benefit analysis (CBA) to assess their financial viability. The WSN technologies include high-end and low-cost wireless sensors for upland crop production with drip irrigation system and lowland crop production with alternate wetting and drying (AWD). Results showed that the high-end WSN technology packages are only viable for high-value crops such as red onion, bell pepper, and hot pepper. The low-cost WSN technology packages are viable for all selected crops except sweet corn. Minimum areas were also generated for each crop …

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

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 …

A Scarcity Of Biospheric Values In Local And Regional Reporting Of Water Issues: Media Coverage In The Floridan Aquifer Region, Sadie Hundemer, Debbie Treise, Martha Monroe

Journal of Applied Communications

The values invoked by journalists in the reporting of water issues influence public support for water policy and the assessment of water tradeoffs. This qualitative framing analysis of water coverage from six newspapers in the Floridan aquifer region from 2010 to 2018 reveals the values used to stimulate reader engagement on a range of water challenges including weather, residential behavior, agriculture, algae, industry, springs, energy, municipalities, and fecal matter. Results reveal a hierarchy of value frames that prioritizes economics and human health, thereby attending primarily to the motivations of egoistic and social-altruistic individuals. The ecosystem implications of deteriorated water conditions, …

Pack It Out Utah: Usu Water Quality Extension Leads Utah’S Statewide Trails And Waterways Cleanup, Lauren Houskeeper, Hope Braithwaite

Outcomes and Impact Quarterly

Utah’s public lands have experienced a surge in outdoor recreation which has led to an increase in garbage on trails, parks, neighborhoods, and eventually, in our waterways. In response, Utah State University Water Quality Extension initiated an annual statewide cleanup to raise awareness and facilitate the proper disposal of litter. During the cleanup events in 2020 and 2021, over 11,000 pounds of trash were removed from our public lands and waterways.

Casting Pearls Before Swine: Why The Public's Darling Right To Pollute Should Have Been Overturned In Recent Scova Decision, Thummim Park

William & Mary Environmental Law and Policy Review

This Note calls for the Virginia Supreme Court to recognize that a city’s right to freely pollute the public waterways is no longer valid under the Virginia Constitution, and to recognize that the line of Darling cases granting municipalities the public right to pollute waterways should have been overturned.

Part I will set out the foundation for this Note. It will discuss the background of Johnson v. City of Suffolk, laying the context for this Note’s discussion. Part II will engage in an analysis of the rationale for Darling. It will contextualize and compare it to current understandings …

Quality Control: Potomac Riverkeeper V. Wheeler & Standards For Qualitative Citizen Water Quality Data In Virginia, Jacqueline Goodrum

William & Mary Environmental Law and Policy Review

This Article explores the issue of quality of citizen data through the lens of Potomac Riverkeeper v. Wheeler, a recent impaired waters listing case concerning the Shenandoah River in Virginia. Part I of this Article provides a brief overview of citizen science data in regulation and policymaking under the CWA. Part II discusses Potomac Riverkeeper v. Wheeler, examining Virginia’s water quality-related data standards and DEQ’s use (and non-use) of citizen water quality-related data and information in that case. Finally, Part III argues that Virginia should establish clear, reasonable, and specific data quality standards for qualitative citizen data so …

Understanding The Perceptions Of Producers Regarding The Ogallala Aquifer Use: A Survey Report (2022), Jonathan Aguilar, Amariah Fischer, Matthew R. Sanderson

Kansas Agricultural Experiment Station Research Reports

This survey asked producers in the Ogallala aquifer how they view their role in groundwater use, what they see as the consequences of groundwater depletion, and why they believe groundwater should be conserved. Producers were also asked about their worldviews and values. Together, these questions help provide an understanding of the cultural state of the Ogallala aquifer, especially as it pertains to groundwater use.

New Strategies For Groundwater Litigation In Texas, Amy Hardberger

William & Mary Environmental Law and Policy Review

This Article evaluates the evolution of the understanding of groundwater rights since the Day decision and assesses the relative power of property rights in groundwater that have emerged and what can be done to equalize resulting inequities. Part I reviews the current state of groundwater ownership rights and includes a brief history of litigation that led to that point. Part II explains the authority and obligations of groundwater conservation districts, which create a regulatory overlay on the common law vested rights through permitting rules and the statewide planning process. Part III summarizes the history of constitutional challenges litigated after the …
