Climate Change And The Co-Production Of Knowledge And Policy In Rural Us Communities, George C. Homsy, Mildred Warner

George Homsy

Climate change requires action at multiple levels of government. We focus on the potential for climate change policy creation among small rural governments in the US. We argue that co-production of scientific knowledge and policy is a communicative approach that encompasses local knowledge flowing up from rural governments as well as expertise and power (to coordinate and ensure compliance) flowing down from higher level authority. Using environmental examples related to land use policy, natural gas hydro-fracturing, and watershed protection, we demonstrate the importance of knowledge flows, power, and coordination in policy creation. Co-production of knowledge and policy requires respect for …

The Effectiveness Of The Endangered Species Act: A Quantitative Analysis, Martin F.J. Taylor, Kieran F. Suckling, Jeffrey J. Rachlinski

Jeffrey J. Rachlinski

Population trends for 1095 species listed as threatened and endangered under the Endangered Species Act were correlated with the length of time the species were listed and the presence or absence of critical habitat and recovery plans. Species with critical habitat for two or more years were more than twice as likely to have an improving population trend in the late 1990s, and less than half as likely to be declining in the early 1990s, as species without. Species with dedicated recovery plans for two or more years were significantly more likely to be improving and less likely to be …

The Difficult Problem Of Nonpoint Nutrient Pollution: Could The Endangered Species Act Offer Some Relief?, Zdravka Tzankova

Zdravka Tzankova

Nutrient pollution of rivers, streams, lakes, and estuaries is one of the preeminent water quality issues in the United States today, and poses a significant threat to the health of aquatic ecosystems. Agricultural nonpoint discharges, the runoff of nitrogen and phosphorous from animal manure and chemical fertilizers, are the primary sources of such nutrient pollution.

A pervasive and long-standing problem, nonpoint pollution, nutri- ent and otherwise, has proven to be one of the toughest challenges in contemporary environmental regulation. This situation is significantly attributable to the political and administrative dynamics of fragmented regulatory authority. The power to control such nonpoint …

Uncertainty, Technical Change, And Policy Models, Erin Baker, Leon Clarke, Jeffrey Keisler, Ekundayo Shittu

Jeffrey Keisler

Both climate change and technical change are uncertain. In this paper we show the importance of including both uncertainties when modeling for policy analysis. We then develop an approach for incorporating uncertainty of technical change into climate change policy analysis. We define and demonstrate a protocol for bottom-up expert assessments about prospects for technologies. We then describe a method for using such assessments to derive a probability distribution over future abatement curves, and to estimate random return functions for technological investment in different areas. Finally, we show how these analytic results could be used in a variety of energy-economic models …

Can The Esa Address The Threats Of Atmospheric Nitrogen Deposition? Insights From The Case Of The Bay Checkerspot Butterfly, Zdravka Tzankova, Dena Vallano, Erika Zavaleta

Zdravka Tzankova

The Bay Checkerspot Butterfly reached its threatened status largely as a result of habitat loss through development. The species now benefits from the habitat pro- tection powers of the Endangered Species Act, yet the biggest new hazard to the survival of remaining Bay Checkerspot Butterfly populations may come from atmospheric nitrogen deposition. Driven by combustion and agricultural emissions, such deposition is an important cause of change in ecosystem structure and function, including potentially critical changes in the remaining Bay Checkerspot Butterfly habitat. We use the Bay Checkerspot Butterfly case to examine whether the Endan- gered Species Act, as it currently …

The Political Consequences Of Legal Victories: Ballast Regulation And The Clean Water Act, Zdravka Tzankova

Zdravka Tzankova

Federal conservation policy has seen a new development recently: the use of the Clean Water Act (CWA) as a tool for regulating ballast water discharges from ships and, thereby, for preventing biological invasions caused by the discharge of nonindigenous organisms in ballast. Some outcomes of this new method for regulating ballast water discharge are obvious, others are much less so. Superimposing CWA regulatory authority on an already existing system of U.S. ballast law and regulation is likely to change the politics of ballast regulation. What do such changes in regulatory politics spell for the future of regulatory protections against biological …

The Science And Politics Of Ecological Risk: Bioinvasions Policies In The Us And Australia., Zdravka Tzankova

Zdravka Tzankova

The US and Australia – western democracies with similar histories of public awareness on environmental issues and broadly comparable records of policy and regulatory action to safeguard environmental quality – have responded differently to one of the newest and most significant threats to marine bioidiversity: that of biological invasions mediated by the ballast water of commercial shipping. Each country has framed the same invasion risks differently for the purposes of policy and regulation: Australia has decided to use a more narrowly circumscribed, target-species-based approach whereas US policy and regulation takes a more comprehensive and precautionary approach. These somewhat surprising national …
