Intertemporal evaluation of household food security and its determinants: evidence from Rwanda

The food security literature has reiterated the importance of having an indicator that simultaneously captures the different dimensions of the food security definition. In this regard, this study builds on previous studies using a harmonized food security indicator within a relatively high frequency panel data from Rwanda to examine the dynamics of household food security. Summary statistics show the transitory nature of food security where households go either from complete state of food insecurity to being partially food insecure or from being partially food insecure to being completely food secure during the harvesting seasons and later fall back to their initial state during the sowing and growing seasons. This underscores the intertemporal dimension and transitory nature of food security over time. We also employed a correlated random effects multinomial logit model to further identify the determinants of households being in any of the identified states of food security. Results suggest that agricultural seasons of major food crops do determine households’ state of food security. Also, household socio-demographic characteristics, household assets, income diversification, and location of the household dwelling are some of the consistent factors that increase or decrease the likelihood of the household being food insecure.
