The consequences of wildfires are felt in susceptible communities around the globe on an annual basis. Climate change predictions in places like the southeast of Australia and western United States suggest that wildfires may become more frequent and more intense with global climate change. Compounding this issue is progressive urban development at the peri-urban fringe (wildland-urban interface), where continued infrastructure development and demographic changes are likely to expose more people and property to this potentially disastrous natural hazard. Preparing well in advance of the wildfire season is seen as a fundamental behaviour that can both reduce community wildfire vulnerability and increase hazard resilience-it is an important element of adaptive capacity that allows people to coexist with the hazardous environment in which they live. We use household interviews and surveys to build and test a substantive model that illustrates how social cohesion influences the decision to prepare for wildfire. We demonstrate that social cohesion, particularly community characteristics like 'sense of community' and 'collective problem solving', are community-based resources that support both the adoption of mechanical preparations, and the development of cognitive abilities and capacities that reduce vulnerability and enhance resilience to wildfire. We use the results of this work to highlight opportunities to transfer techniques and approaches from natural hazards research to climate change adaptation research to explore how the impacts attributed to the social components of social-ecological systems can be mitigated more effectively.

A common assertion in discussions of flooding is that risk perception is critical and is linked to risk‐mitigating behavior. Furthermore, many assert that the adverse effects of floods could be reduced by changes in risk communication, thereby influencing risk perception to foster mitigating behavior. We argue that these assertions are based on quite questionable underlying assumptions: That stakeholders are generally aware of flood risk, that they have the capacity to engage in disaster risk reduction, and that their actions can be effective. The belief in and policies influenced by these three questionable assertions support, in turn, policies that shift responsibility for flood risk reduction onto individuals and homeowners, without regard for social and spatial justice issues. In contrast, we argue that context matters to understanding the complexity of the relation between flood risk perception and behavior, local power relations, and other constraints and opportunities that affect stakeholders. While the academic community has long played a pivotal role in supporting practical flood risk management, future research should take a more critical perspective on the underlying assumptions and focus on improving coordination across theories, methods, and variables, fostering comparative studies across disciplines, contexts, and scales.

. Tim's research has focused on risk and decision making under uncertainty, particularly in relation to individual, community and organizational preparation and response to environmental risk. His most recent work has included foresighting research on natural resource security in Australia, as well as exploring new mechanisms for risk communication with respect to natural hazards like wildfire. Florian Roth is a researcher at the Center for Security Studies. He studied Political Science, History, Arts and Media at the University of Konstanz. His research interests include security risk management, risk communication as well as armed conflicts and peace operations. AbstractToday the majority of the globe's inhabitants live in urban areas, and according to all prognoses, cities will continue to grow in the coming decades. Global cities are also becoming increasingly connected as a result of economic, political, cultural and demographic globalization. In the context of urban security management, the growing complexity these connections bring may present a double-edged sword: global cities can be both the most secure and the most dangerous places to be when disaster strikes. Developing appropriate mechanisms to prepare for and cope with complex crises in cities will, in the future, be a key aspect of security policy-making. In this article we explore current trends in research and practice concerning the management of disasters in eight global cities, particularly focusing on aspects of preparedness, response, urban resilience and cooperation. The results of the study indicate that cities must improve the capacity to predict new or unforeseen risk by diversifying capabilities for risk assessment and improving inter-agency collaborations. In addition, cities must adopt new approaches to disaster management that are sufficiently flexible to adapt to a changing risk environment and to safeguard urban security.
