Assessing food system vulnerabilities: a fault tree modeling approach.

ABSTRACT:

Background

Food system function is vulnerable to disruption from a variety of sources. Disruption of the processes required for food provision may result in decreases in food security in affected communities. Currently, there are few tools that quantitatively predict or analyze food system vulnerabilities to contribute to food system resilience analysis. This work presents a prototype version of one such tool, a fault tree, which can be used conceptually and for future modeling work. Fault tree analysis is an engineering tool used to illustrate basic and intermediate factors that can cause overall system failures.

Methods

The fault tree defines food system functioning as food security at the community level and maps the components of the food system onto three main tenets of
