Sorghum is one of the drought tolerant cereal crops currently under cultivation in Zimbabwe. Semi-arid regions in Zimbabwe are among the areas cultivating sorghum to a large extent, and these regions are most vulnerable and as a result experience food insecurity. Despite the assumption that sorghum has contribution on household food security, a wide assessment has not been done in Zimbabwe to examine the extent of its contribution. The study intended to determine the role of sorghum in enhancing sustainable food security. In Jambezi District food insecurity is still persistent to a large extent; so the district was taken as the case study area. Various methods were used in data collection in which focus group discussions and interviews were employed. The study utilized purposive sampling in order to identify study participants. Extension service were observed to have positive significant influence to the household on becoming food secure. From results generated it was noted that sorghum contributed to households’ food security to the large extent in semi-arid areas if people in Jambezi deviate from traditional maize production. Hence in the semi-arid regions in which vulnerability to food insecurity is high, sorghum production should be more emphasized so that chronic food insecurity may be averted.
