- Risk is produced by the interaction of exposure to hazards in a place and the vulnerability of the people that live there. Research on the factors that influence vulnerability has advanced a conceptual understanding of the uneven nature of risk. Just as many factors, or determinants, of vulnerability interact to shape risk, so too do multiple exposures. The idea that multiple hazard exposures affect local risk is certainly not new in hazards research, but the literature is missing a refined conceptual framework that can articulate how multiple exposures interact with each other, as well as with determinants of vulnerability, to produce unequal risk. Importantly, this framework must be consistent with vulnerability research and grounded in empirical studies that investigate across the factors that influence exposure and vulnerability. This paper seeks to contribute such a framework. It critically reviews the literature on exposure and vulnerability to hazards and submits a refined production of risk framework. The framework is then applied to a case study of Crescent Beach, a coastal community in British Columbia, Canada, to draw conceptual and practical insights to how multiple interacting exposures and unequal vulnerability produce risk. The study findings reveal that exposures, including flood hazards and the rail line that isolates the community, and determinants of vulnerability, including socioeconomic conditions, institutional arrangements, and amenity values, interact in ways that produce unequal local risk.
