Résumé partiel
The dietary shift from indigenous leafy vegetables to cash crops production and consumption increased the risk of micronutrients deficiency diseases, especially among rural-poor communities. The less consumption of ILVs promotes hunger and food insecurity among rural and urban households. An increase in consumption of these leafy vegetables helps minimize malnutrition, hunger, and food insecurity. Each ILV contain different levels of micronutrients, suggesting that diversifying ILVs in consumption has the potential to reduce health conditions associated with micronutrient deficiency. Therefore, understanding consumer acceptance of indigenous leafy vegetables (ILVs) is important in enhancing their consumption levels to increase micronutrient intake. However, the determinants of consumers’ acceptance of ILVs, vis-à-vis its potential impact on household food security, is neglected by researchers, as a result, declining. This study was set out to assess the determinants of acceptance of indigenous leafy vegetables by consumers in Limpopo and Mpumalanga provinces. The study used secondary data that was collected by the South African Vulnerability Assessment Committee in 2016. A total of 1520 respondents were selected from the two provinces using a multistage stratified sampling method. In analyzing the determinants of consumers’ acceptance of ILVs, a seemingly unrelated regression (SUR) model was employed. The results of SUR showed that the gender of the household head, marital status, HIV status, wages/salary, and grants were statistically significant in influencing the acceptance of ILVs by consumers. The study further revealed that amaranth and cleome were the most accepted leafy vegetables while blackjack was the least accepted one. Education and marital status had a negative influence on the acceptance of all leafy vegetables being investigated in this study. While estimating the impact of ILVs consumption on household food security, the household food insecurity access scale (HFIAS) was used to determine the household food security status of the respondents. In the same vein, the endogenous switching probit model (ESPM) was employed to estimate the impact of ILVs consumption on household food security status.
