Résumé partiel
There has been a decline in the production, utilization and diversity of African leafy vegetables (ALVs) such as cowpea leaves, pumpkin leaves, amaranth, collard greens, mustard greens, etc., which poses a threat to the status of food security and development in the sub-Saharan region. Research has shown that ALVs have high market potential and contribute substantially to household incomes, food security, health and nutrition. However, the scientific and donor communities often give less attention to research on, and development of, these crops. This study focuses on the commercial production of ALVs, a relatively new economic activity, in the Limpopo Province of South Africa that may assist rural, small-scale farmers to diversify, improving their economic independence and livelihoods. In attempting to provide an impetus to the ALV industry, the South African government currently offers free training in ALV production, extension services, free high quality seed, free fertilizers and pesticides. Considering the geographical suitability and the magnitude of investment made towards the ALV development programme, there is a need to understand consumer behaviour towards ALVs, and why many farmers are not participating in the industry. There has also been limited research so far on the challenges and opportunities in producing, value adding, and marketing of ALVs in South Africa. This study is, therefore, an attempt to address these knowledge gaps. It also provides an opportunity to draw relevant policy and management implications to inform future strategies in the industry. Given this background, the specific objectives of the study were to : (i) analyse the value chain of ALVs in Limpopo Province ; (ii) examine the factors influencing households’ participation decision in the production of ALVs in Limpopo Province ; (iii) determine the factors influencing consumers’ purchasing decisions and expenditure levels for ALVs ; and (iv) determine socioeconomic and perception factors affecting willingness-to-pay. To analyse the value chain of ALVs in the Limpopo Province of South Africa, prominent value chain actors, institutions governing the chain, infrastructural endowments, key factors and challenges affecting the success or failure of the value chains, were identified. Relationships among the value chain actors were weak, with transactions based primarily on spot markets. While smallholder farmers producing ALVs attain high gross margins, their intention to participate in mainstream markets is impeded by lack of technical knowledge of production, lack of packaging and processing services, poor infrastructure, deficient contractual agreements vi between actors, and lack of access to finance.
