The concept of resilience has recently been introduced into food security literature. It aims to measure households’ capability to absorb the negative effects of unpredictable shocks, as a legitimate component of vulnerability analysis. The definition of resilience to food insecurity has a direct effect on the methodology used to measure it, and the model described in this document, considers resilience to be a latent variable defined according to four building blocks: income and food access; assets; access to public services; and social safety nets. Two additional dimensions – stability and adaptive capacity – cut across these building blocks and account for households’ capacity to respond and adapt to shocks; these too are latent variables.
