The social amplification of risk : theoretical foundations and empirical applications

The article presents the framework of social amplification of risk which integrates the technical assessment and the social experience of risk. Risk perception research has revealed that contextual factors shape individual risk estimations and evaluations. Identification of these factors, such as voluntariness, personal ability to influence risks, familiarity with the hazard, and catastrophic potential, provides useful information about the elements that individuals consider in constructing their interpretation of risks. In addition, analyses of people's heuristics in making inferences have shed some light on how risk information is generalized and evaluated intuitively. These psychological studies fail to explain, however, why individuals attend to certain characteristics of risks and ignore others. Furthermore, in focusing only on the individual as an information processor, these studies exclude from the analysis the social and cultural variance of risk interpretations. The social amplification framework postulates that the social and economic impacts of an adverse event are determined not only by the direct physical consequences of the event, but by the interaction of psychological, cultural, social, and institutional processes that amplify or attenuate public experience of risk and result in secondary impacts

Two Types of Global Environmental Change. Definitional and spatial-scale issues in their human dimensions

Clarification of several issues in the human dimensions of global environmental change is essential to the creation of a balanced research agenda. Global environmental change includes both systemic changes that operate globally through the major systems of the geosphere-biosphere, and cumulative changes that represent the global accumulation of localized changes. An understanding of the human dimen sions of change requires attention to both types through research that integrates findings from spatial scales ranging from the global to the local. A regional or meso-scale focus represents a particularly promising avenue of approach. © 1990

Assessing the Vulnerability of Coastal Communities to Extreme Storms: The Case of Revere, Massachusetts, US

Climate change may affect the frequency, intensity, and geographic distribution of severe coastal storms. Concurrent sea-level rise would raise the baseline of flooding during such events. Meanwhile, social vulnerability factors such as poverty and disability hinder the ability to cope with storms and storm damage. While physical changes are likely to remain scientifically uncertain into the foreseeable future, the ability to mitigate potential impacts from coastal flooding may be fostered by better understanding the interplay of social and physical factors that produce human vulnerability. This study does so by integrating the classic causal model of hazards with social, environmental, and spatial dynamics that lead to the differential ability of people to cope with hazards. It uses Census data, factor analysis, data envelopment analysis, and floodplain maps to understand the compound social and physical vulnerability of coastal residents in the city of Revere, MA, USA

Generic and specific facets of vulnerability for analysing trade‐offs and synergies in natural resource management

International audienceThe concept of vulnerability as the combination of exposure, sensitivity and adaptive capacity to a stressor is gaining traction outside of the climate realm, opening new avenues to address contemporary sustainability issues more holistically. Yet, critical notions that underpin vulnerability have yet to be integrated into its application to natural resource management and non-climatic stressors. In particular, the way generic and stressor-specific facets of vulnerability interact and can inform decision-makers about Here, we investigate the salience of the generic/specific framing in the context of Chilean artisanal fishing communities engaged in rights-based co-management and experiencing pressures from two stressors: poaching and market volatility. Specifically, we draw on market data combined with socio-economic surveys conducted with 446 members and leaders from 42 fisher unions to quantitatively investigate potential trade-offs and synergies between facets of vulnerability to poaching and markets.Generic adaptive capacity (i.e. flexibility, assets, learning, organization and agency) likely facilitated stressor-specific adaptive capacities to both stressors. High levels of specific adaptive capacity to one stressor neither increased exposure nor undermined specific adaptive capacity to the other stressor. However, adaptive capacity did not translate into exposure reduction as expected, suggesting that adaptation barriers may prevent fishers from mobilizing adaptive capacity into effective adaptive action.This study illustrates how breaking down vulnerability into generic and specific facets can help us better anticipate important trade-offs and synergies in management interventions. More generally, it highlights the potential of the climate adaptation and vulnerability literatures in informing place-based management of natural resources
