Vulnerability and biosecurity scholars argue for the need to analyze vulnerability to hazards as a relational process. We propose a network vulnerability assessment that fills this gap by drawing on actor-network theory, rooted networks, and an analytical framework from vulnerability literature that analyzes exposure, sensitivity, and adaptive capacity to hazards. We demonstrate how to conduct such an assessment and the value of this approach through a network vulnerability assessment of North Carolina's hog industry to a potential foot-and-mouth disease (FMD) outbreak. This approach allows us to analyze how power-laden relationships among humans and nonhumans create and stabilize exposure routes for FMD. A relational process allows us to analyze the sensitivity of the network from the unique perspectives of different actants, from which we can see that the relationships of some can trigger the agency of …
