Redescription Of Anaschisma (Temnospondyli: Metoposauridae) From The Late Triassic Of Wyoming And The Phylogeny Of The Metoposauridae, Bryan M. Gee, William G. Parker, Adam D. Marsh
United States National Park Service: Publications
Metoposaurids are non-marine temnospondyls that are among the most common constituents of Late Triassic deposits, but despite their abundance, the evolutionary relationships of the group are poorly resolved and have not been fully addressed with modern phylogenetic methods. The genus Anaschisma is one of a number of poorly resolved metoposaurid taxa and was erected to describe two species from the Popo Agie Formation (Carnian) in Wyoming: Anaschisma browni and Anaschisma brachygnatha. Since being named, the genus has been repeatedly synonymized and separated with other taxa in the context of broader revisions of the Metoposauridae. At present, Anaschisma is considered …

More than half of the population of the continental United States resides in coastal communities, which are increasingly home to commercial shellfish aquaculture operations. Consequently, a variety of user conflicts can arise as states seek to encourage the development or expansion of shellfish aquaculture. Each of these conflicts creates the potential for opposition and legal challenges to the industry.
An understanding of the legal and regulatory context governing shellfish aquaculture can assist in managing conflicts related to the industry. Laws and regulations in some cases create or can be perceived as impediments to the growth or success of the aquaculture …

Implementation Of A Multi-Agent Environmental Regulation Strategy Under Chinese Fiscal Decentralization: An Evolutionary Game Theoretical Approach, Ke Jiang, Daming You, Ryan Knowles Merrill, Zhendong Li
Research Collection Lee Kong Chian School Of Business
Evolutionary game theory (EGT) provides a powerful tool with which to unpack the interactive strategies of polluting enterprises (PEs), local government regulators (LG), and central government planners (CG) in China. Here, the prevailing institutional system of fiscal decentralization sees regulatory mandates set by the CG and enforced at the LG level. This delegation shapes managers' incentives when deciding the degree to which firms will incur costs to reduce pollution and comply with state directives. Manager's choice sets draw shape from decisions at the LG level, where regulators balance the pursuit of environmental quality with the economic payoffs of tacit collusion …

Putting The Blue In The Green New Deal, Jason Scorse, David Helvarg
Working Papers
The Green New Deal (GND) is a U.S. resolution that aims to address economic inequality and global warming through a set of proposed economic stimulus projects. As nearly half of the U.S. populace lives in or near coastal areas, the GND needs to prioritize the sustainable use and preservation of the marine environment – called the “blue economy.” David Helvarg of Blue Frontier and Jason Scorse of the International Environmental Policy Program and the Middlebury Institute of International Studies suggest a series of policy and investment priorities for incorporation of the blue economy into the GND.

Scientists, Uncertainty And Nature, An Analysis Of The Development, Implementation And Unintended Consequences Of The Northwest Forest Plan, Gilbert David Miller
Dissertations and Theses
The conflict in the Pacific Northwest between competing visions of how federal forests should be managed resulted in a political stalemate in the early 1990s. The Northwest Forest Plan (NWFP) was initiated to resolve the demands for maintaining ecosystem processes and biological diversity with the social and economic needs for timber harvest. The foundation for the plan rested with the development of ecosystem management. The intent of this research is to explore the events which led up to the adoption of the NWFP, how it was implemented by the US Forest Service and Bureau of Land Management and the subsequent …

New Standards For An Old Problem: The Role Of The Federal Communications Commission In Fulfilling Space Policy Directive-3, Michael S. Dodge
Space Traffic Management Conference
The recent Space Policy Directive-3, issued on June 18th, 2018, commands several sectors of the federal executive apparatus to reassess their current and future efforts to address space traffic management and space situational awareness issues. The reasons for this Directive can be boiled down to the belief that the continued use of the orbital realm depends on responsible management, which in turn depends on myriad factors that include the development of new technologies, the refinement of data gathering, and the clarification of governmental operational roles. In particular, the Directive calls for enhanced standardization of safety and best practices, …

Effects Of Land Use On Greenhouse Gas Flux In Playa Wetlands And Associated Watersheds In The High Plains, Usa, Dale W. Daniel, Loren M. Smith, Scott T. Mcmurry, Brian A. Tangen, Charles F. Dahl, Ned H. Euliss Jr., Ted Lagrange
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
In the High Plains, U.S., native prairie conversion to cropland agriculture has resulted in a loss of service delivery capabilities from most depressional wet-lands as a result of sedimentation. Restoring historic hydrological conditions to affected wetlands may rejuvenate some services, however, there may be tradeoffs due to emissions of CH4 and N2O. We evaluated the influence of two predominant conservation programs (Wetlands Reserve Program, WRP and Conservation Reserve Program, CRP) on gas emissions (CO2, CH4, N2O) from 42 playas and uplands in the High Plains of Nebraska. Because playa restoration through the WRP is most prevalent in the Rainwater Basin …

Impact Of Carb's Tailpipe Emission Standard Policy On Co2 Reduction Among The Us States, Jaewon Lim, Doohwan Won
Public Policy and Leadership Faculty Research
U.S.Environmental Protection Agency (EPA) set the nationwide emission standard policy, but each state in the U.S. has an option to follow the higher emission standard policy set by CARB (California Air Resources Board) in 2004. There are 14 “CARB states” that follow California’s more restrictive standards. The purpose of this paper is to examine the impact of CARB’s tailpipe emission standard policy. Using the panel dataset for 49 U.S. states over a 28-year study period (1987–2015), this paper found the long-term policy effect in reducing CO2 emission from CARB’s tailpipe standard, and its long-run effect is 5.4 times higher than …

Policies To Overcome Barriers For Renewable Energy Distributed Generation: A Case Study Of Utility Structure And Regulatory Regimes In Michigan, Emily Prehoda, Joshua M. Pearce, Chelsea Schelly
Department of Social Sciences Publications
Because of its environmental damage and now often being the most expensive source for electricity production, coal use is declining throughout the United States. Michigan has no active coal mining and seemingly supportive legislation for distributed generation (DG) and renewable energy (RE) technologies. However, Michigan still derives approximately half of its power production from large centralized coal plants, despite the availability of much lower cost RE DG technologies. To understand this conundrum, this study reviews how Michigan investor owned utilities utilize their political power to perpetuate utility structures that work toward the financial interests of the utilities rather than the …

International Environmental Agreements On Climate Change, Katie Crawford
Scholarly Horizons: University of Minnesota, Morris Undergraduate Journal
This paper analyzes International Environmental Agreements (IEAs) as tools to fight the threat climate change poses on the environment and sustainable development. The paper reviews the literature that provides a theoretical foundation for the IEAs. Particularly, the issues such as the greenhouse gas emissions levels, investments in green technology, the duration of agreements, and the process of negotiation that goes behind these agreements are reviewed. Past agreements (such as the Kyoto Protocol, Copenhagen Accord, and Paris Agreement) are studied to determine their effectiveness and potential problematic aspects related to the contracts.

The Costs Of Obtaining Environmental Outcomes Through Coastal Habitat Restoration, Shea Gould, Matthew G. Interis
Journal of Ocean and Coastal Economics
Studies examining the costs of coastal habitat restoration have focused on the cost per acre of restoration or on cost efficiency of various restoration methods. On the other hand, studies examining the benefits of restoration have focused on various ecosystem services that more directly affect welfare including amenity value, storm protection, nutrient retention and biodiversity. We examine a set of 133 Gulf of Mexico coastal habitat restoration projects to estimate the cost of obtaining average annual habitat units (AAHUs), a measure which captures the quantity and, importantly, quality of habitat restored, which is one of the more direct ecosystem service …

Smith College
Climate Change, Agriculture, And Adaptations: Policy Recommendations For Conservation Agriculture, Sydney Abraham, Mel Dollison
Climate and Society
This paper examines the intersection of climate change and agriculture with a focus on possibilities for sustainable agriculture in a warmer world. The authors consider the impacts (both positive and detrimental) of climate change on food production systems before engaging with a variety of adaptive strategies including crop diversification, genetically modified organisms (GMOs), and conservation agriculture (CA). These strategies are then applied within the context of sub-Saharan agricultural policy. Ultimately, the authors suggest that policymakers should support rural agriculture by prioritizing conservation agriculture as a critical piece of both mitigation and adaptation policy.

Local Entities As Mechanisms For Global Climate Governance, Daniel Vernick, Cameron Stanish, Joshua Hill
Climate and Society
This paper considers the role of local government entities as actors in global climate governance regimes. The authors review traditional state-based climate governance efforts and existing attempts to engage municipal and local actors through transnational municipal networks (TMNs). Arguing for the importance of TMNs to effective and time-sensitive climate action, the authors then show how and why TMNs are crucial to future efforts to address climate mitigation as part of multi-level, holistic plans for global climate governance.

Recognizing And Addressing Risk Ambiguity In Sea Level Rise Adaptation Planning: A Case Study Of Miami-Dade County, Florida, Mary Ann Rozance
Dissertations and Theses
As coastal cities around the world identify and implement adaptations to sea level rise, they are faced with competing interests around what should be done and how to prioritize actions. Often, environmental problems--like confronting the challenge of sea level rise--are posed as requiring expert driven, technical solutions to identify and mitigate risks across the landscape. This framing, however, ignores the way in which diverse knowledge can help inform long-term planning horizons that address complex ways that sea level rise affects communities. The failure to integrate diverse knowledge into sea level rise adaptation can result in barriers to implementation and outcomes …
