This study explores public risk attitudes of environmental hazards with a focus on threats such as air, water and soil pollution or toxicants spillage. We emphasize the social dimension of risk and analyze how strong networks of social connections affect community members' sensitivity to the health risks from pollution-type hazards. We develop a model that integrates the social dimension using aspects like social capital with a set of individual-level factors like people's awareness of environmental issues, knowledge of threats, and experience of health problems. We test our models with US national survey data (N=1207) focusing on health hazards and integrate location-based measures of social capital. Our findings highlight the detrimental (albeit relatively small) effect of strong social networks as residents of communities with high social capital downplay the health threats from hazards and report decreased risk attitudes. We also find important role for individual-level factors led by awareness and knowledge of the threats. Our findings offer unique perspective on risk attitudes by demonstrating the potential harmful effects of strong social ties on community members' sensitivity to health risks from pollution-type hazards. In addition, we offer evidence on factors that shape risk perceptions in the face of less common environmental hazards.

In the United States, debris removal is one of the costliest and most time-consuming elements of disaster response and recovery. It is essential to reducing secondary environmental and health risks, and to community recovery and rebuilding. Analysis of debris removal and waste management, though, primarily treats it as a series of operational steps and technical decisions. In contrast, this article analyses disaster debris removal decision-making as a social process. We present the findings of an ethnographic study that engaged over 70 government actors from federal, state, local, and Tribal agencies in focus groups and interviews. By examining the experiences of these actors, who are central to debris removal decisions, this article identifies decision points that send waste down particular pathways from collection to final disposal. Three operational areas of concern that emerge from the analysis are: local control and capacity, cost and reimbursement, and balance between urgency and sustainability. This article shows how social processes in particular socio-material systems shape these decisions, such as the interplay of waste and disaster institutional arrangements. Finally, it shares practical implications for social process workarounds to operational challenges, such as interagency and interlevel relationships, that can support on-the-ground decision-making.

Migration is often understood to be a livelihood strategy to cope with the effects of environmental threats and climate change. Yet, the extent to which migration decisions differ due to the type, severity, and frequency of environmental events has been little explored. This paper employs household surveys in southwestern Bangladesh to explore this research gap. A multinominal regression model is used to simulate reported future migration decisions (200 sample households) in the context of both rapid-onset (i.e. cyclone and flood) and slow-onset (salinity, siltation, and riverbank erosion) environmental phenomena. Results show: i) previous disaster experience and increasing conflict in the community motivate migration in the near future in the context of slow-onset phenomena (salinity); (ii) economic strength and self-efficacy increase non-migration intention in both contexts of sudden and slow-onset events; and (iii) the extent and pattern of these influences on migration differ across demographics, including education, religion, and age. Importantly, this analysis shows that the relationship between migration decisions and the type, severity, and frequency of environmental events is influenced by socioeconomic conditions. Therefore, this research supports future adaptation planning specifically tailored to the type and exposure of extreme environmental events.

It has been three decades since key leaders gathered to pave a path toward healthier and more just environments and recommendations were made to improve communication between scientists and community stakeholders who can influence decision making. Since that time, community engaged research has flourished while building the capacity of researchers to engage in the work of making change to those environments has lagged. The purpose of this study was the development of guidelines to inform interactions between researchers and decision makers and influencers who participate in the policy change process. This community engaged, pragmatic and iterative inquiry includes insight from a review of existing resources and key informant interviews. Resulting guidelines were piloted, and formative evaluation by community stakeholders informed and resulted in refinement to the guidelines. Strategies for communicating and disseminating scientific evidence are presented as well as tactics that sensitise researchers to the nuances of policy makers' realities so they may serve as a resource for dealing with complex information and decisions. We provide tactics and archived resources in an on-line toolkit that we have cultivated over time to foster effective communication between scientists and those who have a stake in ensuring that decisions are evidence informed.
