The Waters Of Antarctica: Do They Belong To Some States, No States, Or All States?, Linda A. Malone Sep 2019

The Waters Of Antarctica: Do They Belong To Some States, No States, Or All States?, Linda A. Malone

Linda A. Malone

Major issues and complexities arise when one is looking at the international puzzle that is Antarctica. Despite being uninhabited year round and lacking substantial long-term international law rules for sovereignty, states still try to claim their sovereignty over various parts of Antarctica. The consortium of states under the Antarctica Treaty System (“ATS”) then further aggravates these complexities, especially when other states outside of the ATS have been arguing for different regimes and approaches to dealing with Antarctica and resource exploitation. Due to these major issues and a desperate need for a resolution in times of global climate change, this Article …

Reducing Agriculture's Contribution To Nitrate Contamination Of Surface Waters, Dana L. Dinnes, Cynthia A. Cambardella, Thomas S. Colvin, Daniel B. Jaynes, Douglas L. Karlen Aug 2019

Reducing Agriculture's Contribution To Nitrate Contamination Of Surface Waters, Dana L. Dinnes, Cynthia A. Cambardella, Thomas S. Colvin, Daniel B. Jaynes, Douglas L. Karlen

One of the most prevalent environmental issues throughout the Midwest is nitrate (N03) contamination of surface waters. Non-point source pollution resulting from nitrogen (N) fertilizer use on artificially drained agricultural land has been identified as a major contributor to this problem. High levels of nitratenitrogen (N03-N) in water supplies pose risks to humans and livestock (Tyson et. al., 1992), and has cost some communities millions of dollars for N03 removal. The city of Des Moines, Iowa alone has spent in excess of 5.3 million dollars, not including labor costs, for nitrate treatment of its drinking waters from 1992-1996 (Graham, 1997). …


Nitrate Runoff Contributing From The Agriculturally Intensive San Joaquin River Watershed To Bay-Delta In California, Ruoyu Wang May 2019

Nitrate Runoff Contributing From The Agriculturally Intensive San Joaquin River Watershed To Bay-Delta In California, Ruoyu Wang

Ruoyu Wang

Nitrogen loading from agricultural landscapes can trigger a cascade of detrimental e#11;ects on
aquatic ecosystems. Recently, the spread of aquatic weed infestations (Eichhornia crassipes, Egeria densa,
Ludwigia spp., and Onagraceae) in the Sacramento-San Joaquin Delta of northern California has raised
concerns, and nitrogen loading from California’s intensive farming regions is considered as one of
the major contributors. In this study, we employed the Soil andWater Assessment Tool (SWAT) to
simulate nitrogen exports from the agriculturally intensive San Joaquin River watershed to the Delta.
The alternate tile drainage routine in SWAT was tested against monitoring data in the tile-drained area
of …

Introduction: Social-Ecological Resilience And Law, Ahjond S. Garmestani, Craig R. Allen, Craig Anthony Arnold, Lance H. Gunderson Apr 2019

Introduction: Social-Ecological Resilience And Law, Ahjond S. Garmestani, Craig R. Allen, Craig Anthony Arnold, Lance H. Gunderson

Craig Anthony (Tony) Arnold

Environmental law is intimately connected to ecological concepts and understanding. The legal instruments, institutions, and administration of law in the United States are predicated on assumptions that nature is globally stable and that the inherent variability in ecological systems is bounded. This current legal framework is based upon an understanding of ecological systems operating near an equilibrium, or if disturbed, moving back toward an equilibrium. Such assumptions make much current environmental law ill-suited for many pressing environmental issues (Ruhl 1999; Garmestani et al. 2009; Craig 2010; Verchick 2010; Benson and Garmestani 2011). Emerging environmental challenges, such as cross-boundary water governance …


Quantifying Uncertainty And Trade-Offs In Resilience Assessments, Craig R. Allen, Hannah E. Birgé, David G. Angeler, Craig A. Arnold, Brian C. Chaffin, Daniel A. Decaro, Ahjond S. Garmestani, Lance Gunderson Apr 2019

Several frameworks have been developed to assess the resilience of social-ecological systems, but most require substantial data inputs, time, and technical expertise. Stakeholders and practitioners often lack the resources for such intensive efforts. Furthermore, most end with problem framing and fail to explicitly address trade-offs and uncertainty. To remedy this gap, we developed a rapid survey assessment that compares the relative resilience of social-ecological systems with respect to a number of resilience properties. This approach generates large amounts of information relative to stakeholder inputs. We targeted four stakeholder categories: government (policy, regulation, management), end users (farmers, ranchers, landowners, industry), agency/public …

There is a fundamental difference between the ways in which ecologists and lawyers view uncertainty: in the study of ecology, uncertainty provides a catalyst for exploration, whereas uncertainty is antithetical to the rule of law. This issue is particularly troubling in environmental management, where the tensions between law and ecology become apparent. Rather than acknowledge uncertainties in management actions, legal frameworks often force a false sense of certainty in linking cause and effect. While adaptive management has been developed to deal with uncertainty, laws and legal wrangling can be obstacles to implementation. In this article, we recommend resilience-based governance – …


Modeling Spatial And Temporal Variation In Natural Background Specific Conductivity, John Olson, Susan M. Cormier Mar 2019

Modeling Spatial And Temporal Variation In Natural Background Specific Conductivity, John Olson, Susan M. Cormier

John Olson

ABSTRACT: Understanding how background levels of dissolved minerals vary in streams temporally and spatially is needed to assess salinization of fresh water, establish reasonable thresholds and restoration goals, and determine vulnerability to extreme climate events like drought. We developed a random forest model that predicts natural background specific conductivity (SC), a measure of total dissolved ions, for all stream segments in the contiguous United States at monthly time steps between the years 2001 to 2015. Models were trained using 11 796 observations made at 1785 minimally impaired stream segments and validated with observations from an additional 92 segments. Static predictors …
