My thesis examines food allocation and nutritional outcomes in a sample of 152 individuals in thirty-two households of sugarcane workers in the municipality of Gameleira, Northeast Brazil. Anthropometric data show that undernutrition and overnutrition coexist in the study population, and often within households – a consequence of the changes in diet and physical activity linked to the nutrition transition. Food allocation was examined using an indicator of the frequency of consumption of high status foods - non-staple foods which are considered more desirable than staples because they add variety and taste to an otherwise monotonous diet. I created an intra-household index of food allocation in order to observe each individual's consumption in relation to the average in his or her household at two seasonal points of the year. The sample was split into two groups, a group of more affluent households in which high status foods were eaten on the harvest and non-harvest dietary recalls, and a group of less affluent households in which no-one ate high status foods on the non-harvest recall. I found gender biases in the allocation of food in favour of men relative to women, and girls relative to boys, in the higher income group, but no gender biases in the group of less affluent households. In relation to age, I found biases in favour of children relative to adults in less affluent households, but not during seasonal shortage in the higher income households. The biases were greater in households with higher incomes, but lower in households in which women controlled some household income relative to households in which men controlled all income. I considered whether discriminatory behaviour underpins these biases, based largely on periods of observation in a sub-sample of six households, and concluded that food distribution operates as a powerful medium for the expression of differential status among men and women, but not among boys and girls, who have equal status in this population.

Thesis (Ph.D. (Agricultural Economics )) -- University of Limpopo, 2021 / Regardless of the strategies adopted globally and nationwide to fight food insecurity within communities, particularly in the rural context, poverty becomes a major constituent which translates to most rural households experiencing food insecurity shocks. Given the high unemployment rate in South Africa which triggers several household’s vulnerability to food insecurity, the country has diverse natural resources which include indigenous plants such as Indigenous Leafy Vegetables (ILVs), which can be used as food and for business purposes by its residents. Irrespective of the diversity of ILVs in South Africa, there is a significant decline in the production and consumption of ILVs particularly in rural areas where these vegetables are mostly available. In addition, production and consumption of ILVs may not only address food insecurity but these vegetables may benefit households through the income obtained from their sales. The income generated from sales of ILVs may therefore assist towards improving and sustaining rural livelihood needs. Given this background information, the study aimed at assessing ILV production for income generation and food security among rural households in the Eastern Cape Province (ECP) of South Africa. The study was conducted within the three district municipalities of the ECP which were selected because statistics report these districts to be the most affected areas by poverty within the province. These districts are OR Tambo District Municipality (ORTDM), Alfred Nzo District Municipality (ANDM) and Joe Gqabi District Municipality (JGDM). Multistage and proportional random sampling procedures were employed to select households which could participate in the study. Thus, 407 households within these three (3) districts municipalities were used for the purposes of the study. The study also included interviewing role players within the ILV production value chain, thus a snowball sampling procedure was used to select role players. Sixteen hawkers and three input suppliers were interviewed from the three district municipalities. In addition, from the 407 households that were interviewed, 260 households from the three district municipalities reported to be producers of ILVs. A structured questionnaire was therefore used to collect pertaining data allied in achieving the aim of the study. The collected data was captured using Excel 2016, after data cleaning, it was then exported to Statistical Package for Social Sciences (SPSS) version 25 for analysis. Numerous analytical models were used from SPSS 25. For instance, to identify and describe socio-economic characteristics of households, to assess the most produced ILVs from the study areas and to identify role players within the ILV production value chain, descriptive statistics in a form of means, percentages, frequencies, and standard deviation was used. To determine factors which influence production of ILVs, a Binary Logistic Regression Model was used. A Multinomial Logistic Regression model was used to determine factors which influence different uses of ILVs by households and to determine factors influencing food security status among households. A gross margin analysis was used to estimate viability from each ILV produced, harvested and sold, while Household Food Insecurity Access Scale (HFIAS) was used to measure food security status among households. Lastly, a correlation matrix was also used to determine the relationship between the role players and their functions among the ILV production value chain. Based on the results, the study therefore concluded that, from the three district municipalities used in the study, there are various ILVs growing naturally and produced. The production of ILVs from these municipalities is habituated by socio economic characteristics of households, wherein households use ILVs for various purposes which include these vegetables as source of food, medicine and livestock feed. The use of ILVs among households is influenced by socio-economic characteristics and seasonal availability of ILVs in ORTDM, while in ANDM and JGDM, the use of ILVs by households is conditioned by socio-economic characteristics of households, knowledge/ awareness related to nutrition and health benefits of ILVs and seasonal production of ILVs. Furthermore, this research concludes that, ILVs have a potential of diversifying diets and addressing food insecurity problems within rural parts of the three districts. Given the positive gross margins from the three districts, production and selling of ILVs has a potential to contribute to rural household income. Lastly, the study concludes that, the ILV production value chain system lacks governmental support in the form of institutional engagement since there is no evidence of extension officer support from these three district municipalities concerning ILVs production. To this end, the study recommends that, policy makers should further establish inclusion of ILVs in both farming and food systems. Also, government and related institutions which focus on sustainable rural development must intervene in promoting production of ILVs particularly within rural contexts since production of these vegetables may alleviate poverty through job creation, addressing food insecurity and income generation. Thus, a successful intervention of government and policy makers in ILV production would have a potential of translating to sustainable rural livelihoods / National Research Foundation (NRF)

Thesis (Ph.D. Agricultural (Agricultural Economics)) -- University of Limpopo, 2022 / Regardless of the various measures implemented by the South African government to curb food insecurity, majority of rural households are still experiencing food insecurity at the household level. This could be because of the high unemployment rate that the rural households are experiencing, especially in the Limpopo Province. Despite rural household members exerting frantic efforts to acquire education, most of them still find it difficult to secure jobs, which results in them depending on social grants for a living. Still, social grant money alone is not enough to meet their entire families’ needs, including food acquisition. The aim of the study was to analyse food security looking at four dimensions, namely, food availability, access, utilisation, and stability among rural households of Capricorn and Mopani Districts in the Limpopo Province of South Africa. Only two district municipalities in the Limpopo Province, namely, Mopani and Capricorn Districts, were chosen as areas of study. The two district municipalities were chosen because, previous studies and reviews reported that these municipalities are the most affected districts by food insecurity shocks in the Limpopo Province. The study used a cross-sectional survey, where a Multistage sampling procedure was employed. The villages were selected based on probability proportionate to size. The study considered a total of 346 rural households, comprising 173 rural households in each district municipality. A structured questionnaire was used as an instrument to collect data from rural households in the study area. In addition, the collected data was captured using Excel 16. Thereafter, the data was exported to SPSS Version 27 for analysis. Furthermore, to profile the socio-economic characteristics of households, assess food consumption patterns and identify the strategies employed to enhance household food security, descriptive statistics was used. To determine the food security status of rural households in the study areas, the four dimensions of food security were analysed separately. For instance, food availability was analysed using descriptive statistics whereas food accessibility was analysed using Household Food Insecurity Access Scale [HFIAS]. The HFIAS was also used to identify the food security status while Household Dietary Diversity Score [HDDS] was used to measure food utilisation. To measure food stability, a Likert Scale [LS] and descriptive statistics were used. Multiple Linear Regression Models [MRM] were used to determine the factors that influenced rural households’ food security status. On the other hand, the Multinomial Logistic Regression Model [MLRM] was used to examine the determinants of food security among rural households of Capricorn and Mopani district municipalities. The descriptive results established that most rural households from both Mopani District Municipality [MDM] and Capricorn District Municipality [CDM] consume different food groups. In this regard, a minority of rural households are classified as dietary diverse whereas a majority of rural households are still characterised as less dietary diverse due to the limited consumption of different food groups. This reveals that these households range from less food secure to moderate food secure, as illustrated by the food security results. Moreover, the descriptive results also indicated that a majority of rural households in MDM are classified as severely food insecure and that food stability was the component contributing to these households being severely food insecure. As for CDM rural households, the results showed that a majority of these rural households were moderately food insecure with food availability and food stability being the contributing component at CDM. The Multiple linear Regression Model [MRM] results in MDM revealed that the age of the household head, remittances, and access to credit positively influenced food security status. On the other hand, the Multinomial Logistic Regression Model [MLRM] results in MDM revealed that the age of household head, household income greater than R1000, household income between R1099 to R1999, household income between R4000 to R4999, income from salary and access to credit, negatively influence food insecurity status. The Multiple Linear Regression Model confirmed that the male headed households, age of household head, wages, employment status and household income negatively influence food security status in CDM. On the contrary, MLRM results revealed that gender of household head, income from wages, income from salary, old age pension grant, child support grant, household income above R1000 and access to credit for borrowing money positively influenced the food security status of rural households in CDM. In light of this, the study recommends that health practitioners should educate rural households about healthy eating habits and that having a variety of nutritious food type may increase food security. The Department of Agriculture should advise rural households to participate primarily in subsistence farming and that they should focus their agriculture on crops and livestock. This will enable them to enjoy diverse and balanced diets. In addition, the government should empower rural households to participate in development programmes. This may assist households to improve their livelihoods and may also lead to diverse sources of income, which may enhance food security. Furthermore, the government can further assist rural households by providing production inputs (such as seeds/seedlings, fertilizers, and water for irrigation), which may promote food availability, utilisation and accessibility. / NRF-DAAD

The study was prompted by the escalating levels of poverty in Amathole District Municipality of the Eastern Cape Province despite the poverty alleviation programmes that have been established since 1994. The main objective of this study was to identify the underlying factors and challenges that affected agricultural extension organisations in the Amathole District Municipality and explore the role and the prospects of extension organisations as a strategy for development and growth in the district municipality. Data was collected through interviews and with the use of structured questionnaires. The questionnaires were administered to 300 farmers and 20 extension practitioners that had been selected by the systematic random sampling technique in the Amathole District Municipality. After data collection, questionnaires were coded, captured and analysed using MS Excel (2010) and SPSS version 22 (2014). Descriptive statistics were used to summarise the data. Results indicated that although extension officers indicated that they had a positive relationship with the communities they services, farmers indicated that extension policies did not favour them. Conclusions were therefore drawn that agricultural extension organisation was not effective in accelerating development in the Amathole District Municipality. The study, therefore, recommended that further research focusing on the impact of extension services on the economy of South Africa be conducted / Agriculture, Animal Health and Human Ecology / M.

The thesis is comprised in three essays, which combined, fulfill the objectives of identifying the core antecedents of food waste and delineating a typology of food wasters. Additionally, it presents a contextualization of food waste worldwide and a concluding chapter proposes an agenda for future research studies on consumer food waste. Food waste, as a research theme, provides the opportunity for scholarly work in marketing to meet the criteria of managerial, public policy, and societal relevance. In the first article, I describe the drivers of the so-called “food waste paradox”, the identification and analysis of food waste in families with income constraints while presenting the food consumption itinerary and the core antecedents of wasted food. This first essay, based on data collected in Brazilian families, illustrates also how cultural norms, such as over-preparing food to show hospitality or as a form not to be perceived as poor, can generate more food waste. In the second essay, a grounded theory oriented research highlights the role of affection and abundance on consumer food waste. This second study presents a framework with six dimensions of food waste - 1. Affection; 2. Abundance; 3. Multiplicity of choices; 4. Convenience; 5. Procrastination; 6. Unplanned routine - to enrich the theoretical contributions. Based on empirical data collected in American families, it provides novel explanations, such as on how stockpiling comfort foods in abundance – a form of both boosting positive self-emotions and showing affection for kids – can promote more food waste. In sum, the second essay identifies a negative outcome of affection and food abundance in the family context, while providing a theoretically relevant general framework for the food waste phenomenon. Finally, the third essay, drawing from the entire dataset and a new data gathering from ten families, proposes a behavioral typology of household food waste, an original contribution to consumer behavior studies. The identification of five distinct food wasters’ types - (1) Caring mothers; (2) Heavy cooks; (3) Leftovers killers; (4) Procrastinators; (5) Resourceful mothers - contributes to theory, whilst a number of potential implications for nutritional educators and government officials are explored in light of the findings. A comparison of the Brazilian and American samples explains the characteristics of each type identified, showing many similarities in their respective food waste behaviors. Waste levels perceived per country are also compared. Overall, findings from the three studies, such as the itinerary presented and the identification of the major drivers of household food waste, can contribute to maximizing the results of campaigns aimed at mitigating food waste, and they provide insights for retailers interested in sustainability initiatives. Broadly-based, results presented can also be applied to improve hunger relief programs and nutritional education projects undertaken by the public sector or NGOs. / Esta dissertação doutoral, com base em dados empíricos coletados com 50 mães distribuídas no Brasil (n = 30) e nos EUA (n = 20), tem como objetivo fornecer uma melhor compreensão do desperdício de alimento no contexto da baixa renda. A tese é composta por três artigos, que combinados, cumprem os objetivos de identificar os antecedentes do desperdício de alimento e delinear uma tipologia dos desperdiçadores de alimento. Adicionalmente, contextualiza o desperdício global e um capítulo propõe uma agenda futura para estudos sobre desperdício de alimento no âmbito do consumidor. O desperdício de alimento nas famílias, enquanto tema de pesquisa, oferece a oportunidade para o trabalho acadêmico em marketing cumprir os critérios de relevância social, gerencial e para políticas públicas. No primeiro estudo, descrevem-se os fatores do chamado 'paradoxo do desperdício de alimento', a identificação e análise do desperdício de alimento em famílias com restrições orçamentárias, enquanto apresentam-se o itinerário do consumo de alimentos e os antecedentes do desperdício. Este primeiro artigo, elaborado com dados coletados em famílias brasileiras, ilustra também o papel das normas culturais, tais como o preparo abundante de alimento para mostrar hospitalidade ou como forma de não ser percebido como pobre, no aumento do desperdício. No segundo artigo, uma grounded-theory (teoria fundamentada nos dados) destaca o papel do afeto e da abundância no desperdício de alimento familiar. Para enriquecer as contribuições teóricas, este segundo estudo apresenta um framework com seis dimensões do desperdício de alimento (1. Afeto; 2. Abundância; 3. Multiplicidade de escolhas; 4. Conveniência; 5. Procrastinação; 6. Rotina sem planejamento). Baseado em dados empíricos coletados em famílias americanas, este estudo proporciona novas explicações, a exemplo de como o estoque abundante de comfort foods - uma forma de impulsionar tanto emoções positivas para si quanto mostrar afeto para crianças – pode gerar mais desperdício de alimentos. Em síntese, o segundo artigo identifica uma consequência negativa do afeto e da abundância de alimentos no contexto familiar, e apresenta um framework teoricamente relevante. Finalmente, o terceiro artigo, a partir do conjunto de dados dos estudos anteriores e de nova coleta com dez famílias, propõe uma tipologia comportamental do desperdício de alimento, uma contribuição original aos estudos de comportamento do consumidor. A identificação de cinco tipos de desperdiçadores de alimentos - (1) Mães carinhosas; (2) Cozinheiras abundantes; (3) Desperdiçadoras de sobras; (4) Procrastinadoras; (5) Mães versáteis - contribui para a teoria, enquanto implicações potenciais para educadores nutricionais e agentes públicos são exploradas a partir dos resultados. Como uma forma de explicar as características de cada um dos cinco tipos identificados, compara-se aspectos das amostras brasileira e norte-americana, que apresentam similaridades no comportamento de desperdício de alimento. Os níveis de desperdício percebidos por país também são comparados. Em suma, os achados dos três artigos podem contribuir para maximizar os resultados de campanhas de conscientização voltadas à mitigação do desperdício de alimento, e apresentam ideias para varejistas interessados em iniciativas de sustentabilidade. Mais abrangentemente, os resultados apresentados também podem ser aplicados para incrementar programas de combate à fome e projetos de educação nutricional realizados pelo setor público ou ONGs.

This study has assessed the welfare shocks and household food Insecurity in Ephraim Mogale and Greater Tubatse municipalities of Sekhukhune district, Limpopo Province in South Africa. The study identified shocks affecting livelihood at household level and also analysed the food insecurity status of households. The study is restricted only to two local municipalities out of five municipalities in Sekhukhune district. Structured questionnaire was administered for data collection. A total of 200 households were involved in the study with 100 households selected from each municipality. Within each municipality several villages were selected for survey through stratified random sampling selection. Data was collected between 10th July and 22nd September 2014. All response from the questionnaires was tabulated and processed with the use of statistical package for social sciences (SPSS) programme. Three analytical tools were used to achieve the objectives of the study such as, Descriptive statistics, Household Food Insecurity Assessment Scale (HFIAS) and Linear regression model. Majority of households experience different form of shocks in their households. Increase in food prices, high level of livestock disease, drought, death of a household member and chronic illness such as Diabetes, HIV/AIDS and Tuberculosis are the most important shocks experienced. Approximately 22.2% of households were characterized as being food secure, 32.2% as mildly food insecure, 34.2% as moderately food insecure while 11.4% are severely food insecure. The main determinants of food security from the sample survey were education, unskilled wage labour, grants, pension and disability funds whereby high-level of livestock diseases, illness or accidental loss, death of a household member tends to expose households to higher risk of food insecurity. Policy recommendations are made on promoting education in the rural areas. High priority should be given to industrialization in the district which will in turn boost the rate of employment and also add to the economic growth. Policy measures should be made in supporting people and organizations on how to respond to shocks and stresses experienced in their communities. / Centre for Sustainable Agriculture and Environmental Sciences / M.
