Thesis (MSc. (Agricultural Economics)) -- University of Limpopo, 2014 / There are few plant species commercialised significantly globally and food requirements are mainly met by only few species. However, there is an enormous number of under-utilised species that play a vital role in the livelihood of rural households. These species are referred to as indigenous crops. Indigenous crops are adaptable to local agro-ecological conditions even where there is unreliable rainfall, which is the case in many parts of the country, require a minimum production management, mature early, and are easy to harvest and preserve and require less capital investments. Despite all these, in South Africa indigenous leafy vegetables (ILVs) were not commercialised and most researchers did not pay much attention to do research on possibilities of commercialising these crops. Thus this study investigated the economic potential of commercialising indigenous leafy vegetables in the rural South African context in general and in the study area in particular. The objectives of the study were (1) to identify the socio-economic characteristics of ILVs producers in rural areas of Capricorn district, (2), to investigate constraints faced by farmers in commercialising ILVs in rural areas of Capricorn district, (3), to determine the productivity of indigenous leafy vegetables in rural areas of Capricorn district, and (4), to assess different types of marketing channels of ILVs in rural areas of Capricorn district. The study used Stochastic Frontier Production Function to determine the productivity and to assess the socio-economic characteristics of producers of Indigenous Leafy Vegetables. Bubble chart was used to assess the marketing channels whilst consumer data was captured into a statistical package. The results indicated that there are several significant socio-economic factors that affect ILV production and there are also factors which constraint farmers from commercialising ILVs. Productivity of ILVs in the study area varied a lot among farmers; some farmers had a high productivity but most farmers had a low productivity. The results indicated that out of the factors included in the analysis significant production factors were; amount of labour used, cost of hiring tractor service and land devoted to ILVs and inefficiency factors were; gender, age, household size, farming experience, farm size, v hired labour, primary occupation and land ownership. ILV farmers had no formal marketing channels; they sold their product direct to consumers or through hawkers. Therefore, the study recommends the integration of science/modern technology and indigenous knowledge, to improve the productivity of ILVs. Since farmers were not technically efficient, therefore it is important to run workshops that will help them improve their production and marketing skills and how to market their products. Or create booklets that have information on how to efficiently produce ILVs. There should also be awareness campaign on the benefit of ILVs in both rural and urban communities. The study also recommends a multi-disciplinary approach in developing the crop; more stakeholders should be involved so as to make the crop appealing. Finally the study recommends the commercialisation of these crops due to the fact that they have the potential and are demanded in most parts of South Africa.

This study focused on the technical and institutional constraints faced by the vegetable co-operatives with regard to the impact on productivity. Vegetable co-operatives have no access to markets due to their poor performance on productivity and poor quality produce resulting to low prices for the produce such that they cannot compete in a market economy. In this study, the data was drawn from a sample of thirty vegetable co-operatives in the Buffalo City Metropolitan Municipality (BCMM) of the Eastern Cape; obtained through focus group discussions and interviews from each cooperative. The objectives of the study are to measure the productivity of vegetable co-operatives using Total factor productivity analysis (TFP) and profitability of vegetable co-operative using Gross Margin (GM). Followed by the descriptive statistics in identifying and assessing the socio-economic characteristics as well as coping strategies adopted by vegetable co-operatives in BCMM where percentages, means and tables are used looking at the highest frequency. The results show that the vegetable co-operatives in the BCMM are not productive and profitable due to major constraints experienced by co-operatives such as lack of market, information, trainings and business skills, capital, infrastructural facilities, effective extension services that all leads to poor produce quality. Co-operative is said to be profitable and viable if total revenue is greater than the total variable cost which makes the gross margin positive. In this case, the total gross margin is negative. The results showed that the production costs, maintenance (tractor hire, generator hire and servicing) and electricity costs were the major costs incurred in the production of vegetable by the co-operatives.

This study focused on the impact of vegetable sales on household income of hawkers in the Limpopo province. A stratified sampling technique was used. The population of hawkers was selected from the five district municipalities of the province. Three major towns from each district were randomly selected for 366 questionnaire administration. Multiple regression analysis (linear, semi-log and double-log) was used to determine the impact of vegetable sales on the household income of hawkers. The outcome of the study revealed that, nine independent variables had a significant impact on the vegetable sales of hawkers when the linear regression model was applied. On application of the semi-log regression, 11 independent variables had a significant impact on the vegetable sales. Ten independent variables had a significant impact on vegetable sales when considering the double-log regression. The cross tabulation of total sales according to districts showed that an average of 1.6 respondents earned less than R200 which is close to, but lower than R174 which is the poverty line measure in South Africa. The study showed the degree of significance of different variables that have an impact on hawkers’ vegetable sales. Vegetable hawkers generate enough income from their sales to live above the poverty line. The recommendation was that the local municipalities should build new markets and improve the infrastructure of existing markets, and also provide proper sanitation and clean water to avoid unhygienic situations in hawkers’ markets. / Agriculture and  Animal Health / M.
