The role of ad hoc networks in supporting climate change adaptation: a case study from the Southeastern United States

To examine the factors that support adaptation within a regional and sectoral context, this article explores five climate-sensitive sectors in North and South Carolina (Forestry, Government Administration, Tourism, Water Management, and Wildlife Management) and the role of partnerships, collaborations, and networks in facilitating climate adaptation and related activities. Drawing from 117 online questionnaires and interviews with sector leaders across the Carolinas, the article highlights several key functions of networks in regard to supporting adaptation—intra-sector information sharing; monitoring, data collection, and research; and education and outreach. Furthermore, the analysis examines how climate networks in the region have facilitated the development of bonding, bridging, and linking social capital while also noting factors that have constrained the growth and success of both intra- and cross-sector collaboration. Although no formal, or discrete, state or regional cross-sector climate change network exists in the Carolinas, climate adaptations and capacity-building efforts have been supported by ad hoc and decentralized networks, emerging collegial partnerships within and across sectors, and collaborative efforts to pool expertise and resources. The role of different forms of social capital within these networks is discussed in the context of a contentious political environment where support for activities designed to address climate change is limited. These findings enhance our understanding of the social factors and relational processes that shape and influence capacity to adapt to climate change.

Groundwater Depletion and Agricultural Land Use Change in the High Plains: A Case Study from Wichita County, Kansas*

Abstract Shifts in resource availability and resulting land use changes are important research themes for coupled human and natural systems and human dimensions of global environmental change. This study examines the relationship between groundwater depletion and agricultural land use change within a single county in the High Plains, where agro-economic systems and populations are dependent on access to reliable groundwater supplies. Results indicate a significant relationship between high proportionate decreases in groundwater and land being removed from irrigation. This case study strengthens the links among local, regional, and global environmental change, and contributes to a greater understanding of the High Plains in the context of regional sustainability and vulnerability concerns.

Design and evaluation of a local analytic-deliberative process for climate adaptation planning

In the midst of rapidly proliferating engagement efforts around climate adaptation, attention to the design and evaluation of decision support processes and products is warranted. We report on the development and evaluation of a process framework called the Vulnerability, Consequences, and Adaptation Planning Scenarios (VCAPS) process. VCAPS is a systematic approach to integrate local knowledge with scientific understanding by providing opportunities for facilitated, deliberative learning-based activities with local decision makers about climate change vulnerability and adaptation. We introduce the conceptual basis of the process in analytic-deliberation, hazard management, and vulnerability. Our evaluations from eight coastal communities where the approach was applied point to four assets of VCAPS: it promotes synthesis of local and scientific knowledge; it stimulates systems thinking and learning; it facilitates governance by producing action plans with transparent justifications; and it accommodates participant time constraints and preferences.

The Role of Perceived Risk, Uncertainty, and Trust on Coastal Climate Change Adaptation Planning

This study examines support for climate adaptation planning and the role of perceived risk, uncertainty, and trust on adaptation of U.S. coastal communities. This assessment is based on the analysis of web-based questionnaires (n = 137) among state, local, and non-government organization (NGO) planners in Alaska, Florida, and Maryland. Ordinal regression and correlation analysis were used to assess which factors are related to support for adaptation during two planning stages. Findings from this study suggest the influence of perceived risk, uncertainty, and trust on support for climate change adaptation (CCA) varies across two stages of adaptation planning (support for the development of plans and willingness to allocate human and financial resources to implement plans). The disaggregation of planning entities into different study areas and levels of management revealed significant differences in the relationship between perceived risk, uncertainty, and trust and support for CCA planning. These findings have implications for the design of communication and engagement strategies.

Climate-Sensitive Decisions and Time Frames: A Cross-Sectoral Analysis of Information Pathways in the Carolinas

AbstractThis paper analyzes the information dissemination pathways that support climate-sensitive decisions in North and South Carolina. The study draws from over 100 online questionnaires and follow-up interviews with leaders in the forestry, natural resources management, planning and preparedness, tourism and recreation, and water supply management sectors. Participants represented subregions within each state, different types of organizations, and organizations working at different geographic scales. The cross-sector comparison demonstrates diverse information uses across multiple time horizons and a wide range of sector-specific needs and factors that influence how and where decision makers obtain climate information. It builds upon previous research regarding climate decision making by providing a comprehensive view of the patterns of information exchange within a given region. Although all sectors draw from a common pool of federal agencies for historical and current climate data, participants consi...

Negotiating a Mainstreaming Spectrum: Climate Change Response and Communication in the Carolinas

Abstract North and South Carolina have experienced considerable land-use change, urban sprawl and environmental management challenges within the past 30 years that have amplified and interacted with growing impacts from climate variability and change. However, with strong conservative majorities in the legislatures of both states, political tension around the issue of climate change has intensified, increasing the need for sensitive and deliberate climate change response strategies that mainstream action into salient areas of public concern. With data from online questionnaires and interviews with over 100 leaders within the Carolinas, this research explores a number of context-specific socio-ecological factors that influence climate change response activities and the mainstreaming process. Additionally, this study highlights how a key component of mainstreaming climate response action in the Carolinas involves the careful use of public communication frames. As such, mainstreamed climate change response within this region of the USA is often aligned publicly with other relevant areas of concern, not referenced or communicated as climate change response. Focusing on the process of mainstreaming provides a salient opportunity to bridge literatures around the concepts of mainstreaming and communication framing while analysing pathways by which climate change response activities are initiated, developed and enacted.

Exposing Compounding Uncertainties in Sea Level Rise Assessments

Abstract KETTLE, N.P., 2012. Exposing compounding uncertainties in sea level rise assessments. Coastal communities and ecosystems, including those along the Carolina coast of the eastern United States, are at risk to permanent or episodic inundation, contamination of freshwater supplies, and a host of other climate change related environmental hazards due to sea level rise. In order to guide development of mitigation and adaptation strategies, stakeholders will require information on baseline conditions and projections of change. However, the interpretation of impact assessments is not always straightforward given the uncertainties in measuring relative sea level rise, the challenges in predicting the magnitude of change, and the difficulty in acquiring appropriate data and methodologies for quantifying impacts. In addition, many sea level rise assessments are not at spatial or temporal scales most relevant for decision makers. In the context of sea level rise assessments, this study presents a model to describe the various sources of compounding uncertainty that can compromise evaluations and complicate interpretations. Sea level trends and impacts along the Carolina coastline—a region at risk to significant economic and environmental losses—are then reviewed as a means of (1) illustrating the compounding sources of uncertainty and (2) testing the state of our knowledge and identifying information gaps and processing limitations that impede understanding adaptation to sea level rise.

Evaluating Poverty–Environment Dynamics

Developing indicators to more effectively evaluate poverty–environment dynamics and inform policy is an urgent research priority. It is critical that these indicators are used in ways that accurately represent the relationship they are meant to inform. This article evaluates the theory and use of poverty–environment indicators, a relatively new tool developed to aid in the design and evaluation of poverty reduction strategies in the context of environmental change. We argue that while they have great potential, in their current form and use, poverty–environment indicators may contribute to critical misunderstandings of processes on the ground. These issues stem from a problematic and largely unacknowledged process of simplifying particular poverty–environment relationships. This article lays out the problematic character of this simplification process, and suggests how we might address these problems to create more useful understandings of poverty–environment dynamics to inform policy.
