The Strategic And Governance Implications Of Solar Radiation Modification: Perspectives From Delegates Of International Climate Negotiations, Todd L. Cherry, Steffen Kallbekken, David M. Mcevoy, Wai Yan Siu

ODU Articles

The lack of progress in addressing climate change has led to increased interest in solar radiation modification (SRM)—a collection of large-scale interventions that cool the planet by managing the amount of solar radiation that reaches the earth. SRM complicates climate change governance because, in addition to advancing collective action to reduce greenhouse gas emissions, governance needs to restrain unilateral SRM action while balancing diverging actor interests, ethical risks and scientific uncertainty. We survey international climate policy experts for their assessments of the potential for effective global governance of SRM and the likelihood of possible international responses to unilateral SRM scenarios. …

Examination Of Cooperative Extension As A Bridging Organization To Enhance Cross-Boundary Collaborative Water Management, Mark E. Burbach, Stephanie M. Kennedy, Weston M. Eaton, Kathryn J. Brasier, Daran R. Rudnick, Walt Whitmer

School of Natural Resources: Faculty Publications

We explored stakeholders’ familiarity with, trust of, perceived competence of, and shared vision with Cooperative Extension on water-related issues in two states to determine the degree to which Extension is positioned to be an effective bridging organization. Results of surveys in Nebraska and Pennsylvania showed that, overall, neither agricultural producers nor non-farm households were very familiar with Extension. However, both stakeholder groups perceived Extension to be trustworthy, competent, and have similar goals on water-related issues. Extension should renew efforts to bolster its familiarity among these groups to enhance its effectiveness as a bridging organization.
