Abstract: This study was conducted in Nkanga Modiri Molema District Municipalities of North West Province of South Africa. The objective of the study was to determine the implication of climate change on livelihood (Household Food security) and determinants among the small and emerging small-scale maize farmers in the province. A total number of 346 questionnaires were administered to the farmers in the district using stratified random sampling technique. Data were captured and analyzed using the Statistical Package for Social Sciences (SPSS) version 23 and household food insecurity access scale (HFIAS) was employed to categories the food insecurity level. Descriptive analysis was first used to define the data followed by correlation matrix to reveal the variables that are relevant which were used in Binary Logistic regression analysis. However, the results of the analysis expounded some variables that are determinants to the impact of climate change on food security. Furthermore, the HFIAS findings elucidated that about 28.0% are mildly food insecured, 34% are moderately food insecured, while 21% are severely food insecured. It was recommended that the determinants factors such as the source of income, type of farm, land acquired, source of climate change information, the channel of information received on climate change, support received on climate change should be given more attention and addressed. Climate-smart agriculture, as well as conservative agriculture, should be introduced and improved where it has been practiced in the study area.
