This study used cross-sectional survey data to estimate farmers` perceptions of, and commonly cultivated ILVs, factors that influence the participation of smallholder famers in the production of Indigenous Leafy Vegetables and its contribution to household food security]. With regard to farmers` perceptions of ILVs, descriptive results reveal that a majority of the people from the study area share positive perceptions with respect to ILVs. Regression estimates for determinants of participation indicate that the production of ILVs is primarily conditioned by shared perceptions and institutional factors rather than the socio-economic attributes of farmers. Public policies that address the institutional framework (extension, credit, market and social networks) in favour of ILVs are more likely to promote production. Also, more research on the documentation and benefits of ILVs, supported by investments targeting educational campaigns towards promoting positive attitudes and dispelling fears and myths surrounding ILVs, will further promote production. With reference to the contribution of ILVs to food security, descriptive results indicate that participation in the production of ILVs leads to a higher HDDS and a lower HFIAS. Regression estimates further revealed that participation positively contributes to a higher HDDS and a lower HFIAS, suggesting that households who participate in the production of ILVs are more likely to be food secure than non-participants. Therefore, participation in the production of ILVs has significant potential to address household food security.

Food security and self-sufficiency in the rural areas has been and remains a major concern for the South African government. The study aimed to investigate farmer’s perception of factors influencing small-scale vegetable production in Tsengiwe village in the Eastern Cape. The research focus was on the following aspects that may have an influence on small-scale vegetable production: socio-economic factors, production and resource deficiencies and the impact of indigenous leafy vegetables. The researcher conducted several demonstration workshops during the field work. The pilot studies and community engagements were essential to extract knowledge systems embedded in the cultural traditions of indigenous or local communities. The action research was part of the reflective process of broadminded problem solving led by researcher and community. The research approach used a triangulation research method to extract information, whereby both quantitative and qualitative research was used to ensure greater accuracy. The main data collection was obtained from interviews with small-scale farming households in the Tsengiwe area. The study revealed that households were dependent on elderly female pensioners to source food and water. These women received most of their income from social grants and were mainly responsible for all farming activities in the households. Most households attempted to produce vegetables, although food security and self-sufficiency through own production was rarely achieved.Other perceived farming challenges included: lack of market accessibility, irrigation infrastructure, drought, financial limitations and soil degradation. Indigenous leafy vegetables were found to play a nutritional role in times of food shortage and not as much for their medicinal value. The study recommended the following interventions: Support for the elderly women in development and production practices, interventions to address factors affecting vegetable production, improving soil structure, working towards food self-sufficiency, moving away from dependence on mechanisation in rural farming.

Thesis (M.Arch. (Professional))--University of the Witwatersrand, Johannesburg, Faculty of Engineering and the Built Environment, 2016 / Globalisation is a considerable catalyst for the state of the world today, and so it is evident through industrialisation, modernism and capitalism that the power and spatiality of food has shifted. Food has always brought people together as it is an universal language that is understood by everyone. However food no longer exists as this valued product of necessity but has now become a product of consumerism. Large corporations control our food industry which has lead to an economic food crisis where our basic needs have become too expensive. This is a consequence of increased population, demands, immoral farming methods and greed. Not only is it affecting our economies but our natural resources. Food production systems need to change along with our attitude towards the environment. In an age of technology, branding and mass production, people have become disconnected from nature, regarding the food we eat and where it comes from. In South Africa, this has resulted in increased food insecurity, obesity, malnutrition and health risks. The necessity of honest, healthy and nutritious clean-living has been lost. So how can we overcome this pressure before we collapse as a society and as a planet? The quality of food affects our daily productivity, well-being and psyche, our primal need. How can architecture instigate a change for the free food philosophy? How can it challenge profit margins in the food system through urban contexts by re-establishing our connection with nature? Investigating the journey through the history of farming, politics and food, I will observe the gradual change in the food industry from the farmer to corporation to consumer, exposing the cultural power plays, which can be reconsidered through architecture. This thesis proposes an holistic approach towards propagating parks and public spaces through food education in an urban context. It concentrates on re-igniting the relationship between man and nature through small-scale agriculture using small-scale architecture: ‘agritechture’. Establishing its roots in Joubert Park, Park Station Precinct, Johannesburg, the strategy unfolds biophilia characteristics observing the intricacy of Persian architecture and soil structures stimulated by modular systems, grid proportions and layering. The prairie ecosystem becomes a precedent study for heterotopian architecture rooting itself as homogeneity. Creating catalytic nodes of urban renewal, it unifies communities while defending its territory, similar to the original African settlement, ‘the Kraal’. / MT2017

Thesis (MTech (Physical Sciences))--Cape Peninsula University of Technology, 2005. / A research study into heavy metals in the Cape Town area, found significant amounts of potentially toxic metals such as lead, cadmium, chromium and iron leaching into the underground aquifer. A further additional study conducted on a community garden in Khayelitsha, showed that vegetable crops have the tendency to accumulate certain heavy metals if they are present in soil and water resources. This study was centered around the Philippi Horticultural Area, which is a large significant farming area within the Cape Metropolitan Region. The significance of the study lies in the fact that at least 50% of the local farmers' produce is sold directly to street traders, residents, local supermarket-chains and restaurants. The remainder of the produce is sold at the Epping Market. The purpose of this study was to investigate heavy metal accumulation in various vegetable crop species taken from some of the local farms in the Phillipi Farming area with the objective to: • investigate heavy metal accumulation in various vegetable crop species taken from some local farms in the Phillipi Farming area. • determine the concentrations of heavy metals present in water and soil resource since these will be the primary source of heavy metals to the vegetables. • determine the soil pH and soil organic matter as these two factors would determine the bie-availability ofthe heavy metals. • identify those crops that pose a definite health risk by means of comparing the determined results to the allowed limits.

Urban agriculture is a strategy poor urban, informal settlement residents adopt to reduce poverty and improve food security and child nutrition. It is widely asserted in the literature and development circles that household vegetable gardens can provide a significant percentage of recommended dietary allowances of macro- and micro-nutrients in the diets of pre-school children. These children are vulnerable in terms of food access and nutrition. The first five years of a child’s life are crucial to psychological well-being. This study set out to determine the impact of home gardens on access to food, dietary diversity and nutrient intake of pre-school children in an informal settlement in Eatonside, in the Vaal Region, Johannesburg, South Africa. The home gardening project was undertaken in five phases, namely the planning phase; a baseline survey (including quantitative food intake frequencies, 24-hour recall, individual dietary diversity questionnaires and anthropometric measurements); a training programme on home gardens; planting and tending the gardens and evaluating the impact of home gardens on access to food, dietary diversity and nutrient intake of pre-school children. Children aged two to five years (n=40) were selected to participate in the study. The sample population consisted of 22 boys and 18 girls. The children were categorised into three groups at the start of the project: children of 24-35 months (four boys and one girl), 36-47 months (four boys and five girls) and 48-60 months (14 boys and 12 girls). All but 10 per cent of the children’s consumption of foods in the food groups increased. At the start of the project, low consumption rates were observed for white tubers and roots, vitamin A-rich fruit, other fruit and fish. After the gardening project, the number of children consuming vegetables increased considerably. There was an increase in the intake of food groups over the period of the project. The number of children consuming vitamin A-rich increased the most, with all children (45 per cent improvement) consuming vitamin A-rich vegetables at the end of the project, compared with just over half at the start of the project. The consumption of vegetables increased with 78 per cent of the children consuming beans and 33 per cent beetroot. Most children (95 per cent) consumed cabbage, carrots and spinach post-home gardening. Seventy eight percent of children consumed beans by the end of the project, but only a third of the children had consumed beetroot during the post-project survey period. Intakes of all nutrients considered in the study improved by the end of the project, except for energy and calcium, which dropped marginally, but both remained at around 50 per cent below requirements. Twenty five percent of boys (24-35 months) were underweight and below the 50th percentile at the pre- and post-project stages. The same boys were severely stunted (on average -4.41 standard deviations below the third percentile). Of the boys aged 36-47 months, 25 per cent were stunted pre-project, but by the end of the project, this number had decreased to 50 per cent. Twenty one per cent of the older boys (48-60 months) were within their normal height for age. Twenty five per cent of girls were underweight (36-47 months). A slight change was observed in the 36-47 month group, where the mean changed from -0.14 standard deviations (below 50th percentile) pre-project to -0.5 (below 50th percentile) post-project. All girls aged 24-35 months were below -2 standard deviations pre-project. After the home gardening project, the figure dropped to 50 per cent. For girls aged 36-47 months, 25 per cent were below -3 standard deviations after the project, compared with 20 per cent pre-project. Height-for- age for girls aged 36-47 months dropped by 10 per cent below -2 standard deviation post-home gardening. Girls from 24 to 35 months were severely stunted [-3.02 (below 3rd percentile) pre- and -2.31 (below 5th percentile) post-project]. Stunting was observed in 36-47 months girls who had means of -2.39 (below 3rd percentile) and 1.86 (below 25th percentile) both pre-and post-gardening respectively and were at risk of malnutrition. The older girls were well nourished with means of height-for-age at -0.88 (below 50th percentile) pre-project and -0.92 (below 50th percentile) post-project. Home-gardening improved food access, dietary diversity, energy, protein, carbohydrate, fat, fibre, vitamin A and iron intakes, but did not make a significant impact on the malnutrition of the children in the project or ensure adequate intakes. Home gardens had a positive impact on height-for-age scores; but had no significant impact on mean weight-for-age and height-for-weight z-scores of the pre-school children. Increases in carbohydrate and fat intakes were shown to have the only significant impact on the children’s nutritional status and only with regard to improving height-for-age scores. The results show that the gardens did not have the expected impact on children’s nutrition, but confirm that increases in incomes from gardening are likely to have a greater impact through savings from consuming produce grown and selling produce to buy energy-dense foods for the children. This needs to be considered in nutrition interventions. / Thesis (Ph.D.)-University of KwaZulu-Natal, Pietermaritzburg, 2010.
