Modern food production is a complex, globalized system in which what we eat and how it is produced are increasingly disconnected. This thesis examines some of the ways in which global trade has changed the mix of inputs to food and feed, and how this affects food security and our perceptions of sustainability. One useful indicator of the ecological impact of trade in food and feed products is the Appropriated Ecosystem Areas (ArEAs), which estimates the terrestrial and aquatic areas needed to produce all the inputs to particular products. The method is introduced in Paper I and used to calculate and track changes in imported subsidies to Swedish agriculture over the period 1962-1994. In 1994, Swedish consumers needed agricultural areas outside their national borders to satisfy more than a third of their food consumption needs. The method is then applied to Swedish meat production in Paper II to show that the term “Made in Sweden” is often a misnomer. In 1999, almost 80% of manufactured feed for Swedish pigs, cattle and chickens was dependent on imported inputs, mainly from Europe, Southeast Asia and South America. Paper III examines ecosystem subsidies to intensive aquaculture in two nations: shrimp production in Thailand and salmon production in Norway. In both countries, aquaculture was shown to rely increasingly on imported subsidies. The rapid expansion of aquaculture turned these countries from fishmeal net exporters to fishmeal net importers, increasingly using inputs from the Southeastern Pacific Ocean. As the examined agricultural and aquacultural production systems became globalized, levels of dependence on other nations’ ecosystems, the number of external supply sources, and the distance to these sources steadily increased. Dependence on other nations is not problematic, as long as we are able to acknowledge these links and sustainably manage resources both at home and abroad. However, ecosystem subsidies are seldom recognized or made explicit in national policy or economic accounts. Economic systems are generally not designed to receive feedbacks when the status of remote ecosystems changes, much less to respond in an ecologically sensitive manner. Papers IV and V discuss the problem of “masking” of the true environmental costs of production for trade. One of our conclusions is that, while the ArEAs approach is a useful tool for illuminating environmentally-based subsidies in the policy arena, it does not reflect all of the costs. Current agricultural and aquacultural production methods have generated substantial increases in production levels, but if policy continues to support the focus on yield and production increases alone, taking the work of ecosystems for granted, vulnerability can result. Thus, a challenge is to develop a set of complementary tools that can be used in economic accounting at national and international scales that address ecosystem support and performance. We conclude that future resilience in food production systems will require more explicit links between consumers and the work of supporting ecosystems, locally and in other regions of the world, and that food security planning will require active management of the capacity of all involved ecosystems to sustain food production.

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.

Information on the present situation of household food insecurity in South Africa is fragmented. There is no comprehensive study comparing different indicators of household food security. Better information on the household food security situation in South Africa would permit relevant policy formulation and better decision-making on the allocation of limited resources. The availability of a national dataset, the first South African National Food Consumption Survey data (1999) , provided the opportunity to investigate some of the issues raised above, and to contribute to knowledge on the measurement of household food security. The aim of this study was to use the data from the 1999 National Food Consumption Survey (NFCS) to : • Determine and compare the prevalence of household food insecurity using different indicators of household food security ; • Determine the overlap of households identified as food insecure by the different indicators (i.e. how many of the same households are identified as food insecure); and to • Investigate whether there was any correlation between the indicators selected . The indicators of household food security selected were: household income, household hunger experienced, and using the index child: energy and vitamin A intake (from 24 Hour Recall (24HR) and Quantified Food Frequency data), dietary diversity (from 24HR data) and anthropometric indicators stunting and underweight. The cut offs to determine food insecure household were those used in the NFCS and the cut off for dietary diversity was exploratory. The main results of the study were as follows : • The prevalence estimates of household food insecurity ranged from 10% (underweight indicator) to 70% (low income indicator). Rural areas consistently had a higher prevalence of household food insecurity than urban areas . The Free State and Northern Cape provinces had higher levels of household food insecurity, with the Western Cape and Gauteng the lower levels of household food insecurity . • Quantified Food Frequency (QFF) data yielded lower prevalence of household food insecurity estimates than 24 hour recall (24HR) data. Household food insecurity as determined by low vitamin A intakes was higher than that determined by low energy intakes for both the 24HR and QFF data . • There was little overlap with the indicators (9-52%), indicating that the same households were not being identified by the different indicators. Low dietary diversity, low income, 24HR low vitamin A intake and hunger had higher overlaps with the other indicators. Only 12 of 2826 households (0.4%) were classified by all nine indicators as food insecure. • The dataset revealed a number of statistically significant correlations. Overall , low dietary diversity, low income, 24HR low energy intake and hunger had the stronger correlations with the other indicators. Food security is a complex, multi-dimensional concept, and from the findings of this study there was clearly no single best indicator of household food insecurity status. Overall , the five better performing indicators (higher overlaps and correlations) were : low income, 24 hour recall low energy intake, 24 hour recall low vitamin A intake, low dietary diversity and hunger; this merits their use over the other selected indicators in this study. The indicator selected should be appropriate for the purpose it is being used for, e.g. estimating prevalence of food insecurity versus monitoring the long term impact of an intervention. There are other important criteria in the selection of an indicator. Income data on a national scale has the advantage of being available annually in South Africa, and this saves time and money. The 24HR vitamin A intake and 24HR energy intake indicators has as its main draw back the skill and time needed to collect and analyse the information, which increases cost and decreases sustainability. Dietary diversity and hunger have the advantage of being simple to understand, and quicker and easier to administer and analyse. It is suggested that a national food security monitoring system in South Africa uses more than one indicator, namely : 1) household income from already existing national data, 2) the potential for including a hunger questionnaire in the census should be explored, and 3) when further researched and validated, dietary diversity could also be used in national surveys. / Thesis (M.Sc.)-University of KwaZulu-Natal, Pietermaritzburg, 2006.

Crop production is widely promoted as a solution to food insecurity, but its real impact on household food security has not been measured in South Africa. Small-scale production is a common practice for many rural poor households of South Africa. While agriculture may play a major role in reducing food insecurity, agricultural growth alone cannot solve the problem of food insecurity at household level. South Africa is food secure at the national level, but available data suggest that between 58.5 and 73 percent of South African households experience food insecurity. This study set out to measure the impact of crop production on household food security among sampled households in two communal regions, Umbumbulu and Maphephetheni, of KwaZulu-Natal, to establish whether participation in food production improved household food security. Household surveys which explored the types of crops produced, food consumed, income obtained from crop sales and the food security situation, were carried out at Umbumbulu and Maphephetheni respectively (n = 200 and n = 68). The types of crops produced were investigated using crop production seasonality charts, while the household food security situation was measured using the Coping Strategy Index tool. The main findings of the study indicated that household gardens provided food for household members, but did not provide sufficient quantities to meet year-round consumption requirements. Most sampled households relied largely on purchased foods. More than 80% of the food consumed by households came from purchases, 4% and 13% came from own production in Umbumbulu and Maphephetheni respectively. Among the households surveyed, 58% and 89% were below the poverty line for Umbumbulu and Maphephetheni respectively. Umbumbulu and Maphephetheni’s largest household income contributions came from wages or salaries. Social grants were the second most important source of household income. As participation in crop production alleviated food shortages somewhat, its contribution to food security cannot be ignored. A study needs to be conducted to investigate whether participation in both farm/non farm activities reduces the number of households below the poverty line. Government should provide extension officers to monitor and evaluate the impact of gardens on household food security. To guide the design and implementation of commercial and home gardens, households need to develop clear and consistent policies, strategies, processes and procedures, and (a sound) monitoring and evaluation framework. / Thesis (M.Sc.)-University of KwaZulu-Natal, Pietermaritzburg, 2007.

This study set out to investigate the food insecurity coping strategies of sample households from the Embo community in the Umbumbulu district of KwaZulu-Natal. A total of 151 Ezemvelo Farmers' Organisation and 49 non-EFO members were interviewed in two rounds, beginning in October 2004 and March 2005. The total sample included 200 respondents from 176 households. A survey questionnaire was used to collect data on socio-economic characteristics, food consumption patterns and application of consumption coping strategies. The study used the Coping Strategy Index to establish the food security status of the households by calculating and comparing the Coping Strategy Index Scores of households. Households applied short-term food consumption coping strategies to cope with food shortages and resorted to short-term income coping strategies when they experienced income shocks. Coping strategies employed by households were effective in mitigating food insecurity. Most strategies applied by most households were not detrimental to livelihoods and did not compromise future household food security. Food insecurity increased the frequency and severity of application of coping strategies employed by households. Households ate less preferred foods, skipped days without eating and ate wild foods. These coping strategies were particularly dangerous to households as proper nutrition is critical for ensuring healthy and productive lives. Food security interventions need to support beneficial coping strategies currently employed by households. Relevant stakeholder like the Departments of Health and Social Development need to target nutritional interventions through workshops and training with vulnerable households. Supporting protective coping mechanisms entails protecting entitlements to land, water resources and productive and non-productive assets. Agricultural production improved the incomes and food consumption of the sampled households. Sustainable agricultural production should be promoted and sustained at household level. The Ministry of Agriculture and local development agencies should assist the community by providing production inputs, for example, provision of vegetable seeds, mechanisation, infrastructure and information on improved production techniques to encourage greater productivity and wider engagement in agriculture. Home gardens could make iii valuable contributions to family food supply and income. The Ministry of Agriculture and local development agencies should give more advice through extension and training services, providing support through negotiation of contracts with suppliers. While agriculture may play a major role in the reduction of food insecurity, attention should also be given to the promotion of non-farming activities, particularly those that can reduce food insecurity. The community and households should actively engage in the design and implementation of policies government policies and strategies for farm and non-farm interventions. / Thesis (M.Sc.)-University of KwaZulu-Natal, Pietermaritzburg, 2008.

This dissertation examines how concerns about food system transformations affect how middle class consumers in Islamabad, Pakistan, perceive and approach food consumption in their everyday lives. The dissertation is situated in the context of risky food environments and food fears resulting from intensified, industrialised, and increasingly lengthened global food systems. Working within food geography and food environments paradigms, this dissertation explores how the transformation of food systems is associated with increasing anxiety about food security and safety for middle class urban consumers in Islamabad. Qualitative data gathered from semi-structured interviews and participant observation is used to illustrate the effects external influences, such as energy scarcity and violent events, have on everyday food environments. The dissertation examines the ways in which conceptualisations of 'good food', and trust relationships are negotiated in these dynamic food environments. The intensely geographical nature of these food environments and food systems, and the role of place-specific contexts on perceptions and adaptations related to food anxieties are emphasised. Situated in literatures on food anxiety and food consumption emerging from geography, food studies, and anthropology, this dissertation challenges dominant discourses on alternative and ethical consumption in a globalising food system. The results of this research not only contribute to literature on South Asia, but also contribute to consumption practices of a burgeoning middle class in developing countries.

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.
