Smallholder farmers encounter countless challenges that not only restrict them from maximizing market opportunities but also limit their access to the markets. This paper aims to achieve a thorough understanding of the factors that influence the market participation of indigenous crops by smallholder farmers while also analyzing the extent of market participation in South Africa. An analyzable sample size of 1,520 was used for the study. Household commercialization index (HCI), T-test, description analysis, and a double hurdle model with quasi-maximum likelihood fractional response model were employed to analyze the commercialization and extent of commercialization among indigenous crops by smallholder farmers in South Africa. The study demonstrated that a farmer's decision to participate in the market is highly dependent on gender, off-farm income, access to market information, and a family member being infected by HIV. Factors such as household size and access to the market had statistical significance in the extent of market participation by smallholder farmers. While we recommend the need to intensify appropriate training for farmers and extension workers involved in the area of indigenous crops, it is also important that indigenous crops are given the necessary considerations by the government and research institutions so that their demand in the market could increase. There is a need to develop a clear support plan for the few farmers that have decided to be involved in the farming of indigenous crops even though they are not highly marketable. On the other hand, there is also a need for consumer awareness campaigns in South Africa, on the income and nutritional benefits of indigenous crops.

Market participation by smallholder indigenous crop farmers holds significant potential for the alleviation of food insecurity and poverty amongst rural households. Smallholder farmers generally play a vital role in the production and marketing of indigenous crops in South Africa. However, smallholder farmers continue to remain among the food-insecure populations. This is more worrisome for indigenous crop farming households whose produce is far more limited in the market yet may contribute towards improving their food security status and livelihoods. This study analysed the impact of market participation of indigenous crops on the household food security of smallholder farmers in the Limpopo and Mpumalanga provinces of South Africa. A sample size of 209 indigenous crop producers were selected from a population of 1520 smallholder farmers. The study adopted a multi-stage stratified random sampling technique. The data were collected using both qualitative and quantitative research and were analysed using descriptive analysis, Household Food Insecurity Access Scale (HFIAS), and the Poisson regression model with the endogenous treatment model. The household size, marital status, household members living with HIV, and access to extension services were found to be positive and significant in determining household food security, whereas the disability of a household member was significant but negative. While the number of smallholder farmers involved in the production of indigenous crops is still limited, enhanced marketing of indigenous crops may improve the food security status of smallholder farmers. There is still a need for the government to channel its interventions towards the indigenous crop production sector, and this may include the provision of trained extension officers to assist smallholder farmers. Policymakers need to develop policies that support the production and marketing of indigenous crops. More awareness and promotion of indigenous crops are needed to encourage more smallholder farmers to adopt this farming practice. Further study of smallholder indigenous farmers across nine provinces of South Africa should be conducted to obtain deeper and broader insights into the role of these farmers on household food security.
