Two of the challenges facing Africa in the 21st Century are effective use of restricted water resources and ensuring food security especially for poor communities. In line with these aims, the eThekwini municipality has introduced a multi-tier system of water supply ranging from full pressure reticulated systems along with flush toilets to standpipes and dry toilet systems. In the latter case, it was soon recognized that the disposal of greywater presented a problem. Bearing in mind that South Africa is already a water scarce region, research was initiated into finding means of using this water as a resource rather than as a waste. Initial on-site trials using the greywater to irrigate crops proved popular and it was then regarded as necessary to test the possible health effects on the communities of such a system. A controlled field trial using pot plantings of a selected range of edible vegetables was initiated at the University of KwaZulu-Natal. Crops were tested both internally and externally for a range of indicator and potentially pathogenic organisms. Quantitative Microbial Risk Assessment (QMRA) techniques were used to assess the health risk to communities from growing and eating the greywater- irrigated vegetables. Although there was a health risk related to most of the activities, especially the handling of the greywater itself, the risks could be brought within the World Health Organisation guidelines of less than one case of disease per 10 000 people per year by the implementation of simple barrier interventions. The greywater irrigated crops themselves, did not present a statistically higher risk of infection than the crops irrigated with either hydroponic solution or tap water. These findings show the importance of applying QMRA to each case to determine health risk. This would allow the productive use of greywater and other water sources in the correct circumstances, thus providing food sustainability for people who currently do not have access to the levels of high purity water currently recommended for agriculture. / Thesis (M.Sc.)-University of KwaZulu-Natal, Westville, 2010.

Inadequate nutrition in preschool-aged children in an urban indigenous community outside of Santo Domingo, Ecuador has a negative impact on growth and development. Nutritional assessments have shown that children are underweight and that there are some effects of stunting and wasting in the population. This study was conducted to assess the extent of food security in this indigenous community in preparation for addressing two of the Millennium Development Goals for 2015: reducing the under-five child mortality rate by two-thirds and eradicating extreme poverty and hunger. An aim was to validate on-site assessment measures in this indigenous community regarding geographic circumstances, transportation, food culture systems and other barriers to food intake. These are interrelated and impact nutritional data collected on Tsáchila families in Ecuador. Mixed methods research were conducted to examine the factors that contribute to nutritional intake. The results showed observed food intake was less than food intake reported on the FFQ. Micronutrient and macronutrient levels, weight-for-height and height-for-age measures were below the WHO standard deviations for Z-scores for this population.

As food insecurity increases among socio-economically marginalized populations, community based efforts to address these issues have received particular attention for their potential to promote justice in food systems. This thesis presents a case-study analysis of right to food (RTF) activism in Vancouver’s Downtown Eastside (DTES), a community where decades of failed government policies and economic disinvestment have produced high levels of poverty as well as organized resistance and activism. I explored this localized movement through key stakeholder interviews (n=17) and 10 months of participation at a community-based organization. My findings suggest that local efforts to organize around RTF may have had some success in challenging the dominant discourse and practices associated with the entrenched charitable food model. However, these efforts are limited in their ability to ‘scale up’ this work to transform the systems that produce uneven urban food environments. I argue that the barriers to food access in the DTES are inextricably tied to broader historical contestations over urban space produced by processes of capitalist urbanization. Drawing on Lefebvre’s ‘right to the city,' I suggest how RTF activism in the DTES could benefit from linking more explicitly to the collective struggles facing wider efforts to reclaim the city.

Emerging favourable as well as unfavourable nutrition patterns are observed in societies undergoing rapid social and economic change. The aim of this thesis is to analyse the associations between household and maternal resources and infant and young child feeding habits and nutritional status in rural Nicaragua, a low-income transitional society. All households (n=1,500) in Los Cuatro Santos with at least one child (0-3 y) were visited to collect information on feeding of the youngest child. Children´s anthropometry was also measured using standardised World Health Organisation (WHO) techniques. Validated instruments were used to assess household and maternal resources. All instruments had been adapted to the local context and piloted in a nearby community.  The education of the mother showed more independent variation in the studied outcomes. The odds for exclusive breastfeeding were highest in infants aged 0 to 5 months of mothers with the lowest education. Further, children aged 6 to 35 months with lowest educated mothers were less likely to consume highly processed snacks (HP snacks) and sugar-sweetened beverages (SSBs). They were also less likely to be exposed to a double burden of suboptimal feeding (concurrent unmet WHO recommended feeding practices and consumption of HP snacks or SSBs). However, children aged 6 to 35 months were more prone to infrequently meet dietary diversity and to more shortness. Children in the same age group with lower educated mothers were also shorter in households with the lowest housing quality. Higher level of maternal education contributed both favourably and unfavourably to child feeding and nutrition. This was reflected in more and less frequent practice of the WHO feeding indicators, but also in more frequent children´s consumption of HP snacks and SSBs. Higher maternal education was associated with taller children, even in households with the lowest housing quality.

Using technology as an entry point, I employ the concept of the ecology of practice as a lens to interpret a specific food security intervention on small millets –neglected and underutilized crops important to rainfed agriculture. The “Revalorizing small millets: Enhancing the food and nutritional security of women and children in rainfed regions of South Asia using underutilized species (RESMISA)” project objectives each evoked technology to: increase production, decrease women’s drudgery, and increase the status of small millets. I examine networks of actors, ecologies and technologies in the Nepal project sites using a multi-sited ethnographic approach. Analyzing three types of technologies (seed, machines and practices), I found divergences between natural and social scientists’ perceptions on technology development. Interests differed among the worldviews of smallholder farmers that the researchers sought to engage as participants. Understanding practices in specific ecologies matters as research for development efforts seek to close the technology adoption gap.

Cultural oppression and marginalization through colonization of First Nation peoples has led to a variety of physical and mental health problems. Regaining health and well-being in these First Nations communities will require interventions sensitive to cultural needs and supportive of traditional practices. Anthropogenic induced climate change has the potential to warm the region around the Hudson and James Bay lowland by 3.9-4.5 ??C. This warming will affect both the traditional and conventional food system in the communities on the western James Bay coast. Western James Bay First Nations already face high levels of food insecurity. The traditional food system is becoming weakened as people participate less in hunting activities, and will become further degraded as climate change makes hunting practices more risky and expensive. However, climate warming may provide greater cultivation potential in the region improving local production of produce if these activities are pursued. Home gardening and community gardening have the potential to improve access to fresh vegetables, nutritional choices, and community cohesion if pursued in First Nations communities.

In recent decades, environmental problems associated with conventional agriculture, children’s nutrition, and concern over the adequacy of the current food supply have led to the emergence of the sustainable food and food security movements. These issues have also inspired the state of California to pass legislation to place a garden in every school in the state. This thesis analyzes the accuracy of this policy’s implementation and its effects on the sustainable food and food security movements. Research found that the loss of state funding for this policy and the administrative, logistical, and informational barriers to establishing garden education programs has meant that only about a third of California schools have gardens. The gardens that do exist demonstrate excellent benefits in terms of educational and nutritional goals, but only help the sustainable food and food security movements to a limited extent. Suggestions for future improvement include obtaining state funding for the program once more, expanding existing gardens to produce more food and increase the impact on food production issues, and increase informational and technical support for teachers. Nevertheless, the program has been successful at establishing itself and is continuing to grow, thus showing great promise for the future.

This study was conducted in conjunction with the Saskatoon Regional Food Assessment with the intent of identifying structures that contribute value and promote engagement among participants. Currently, the assessment process lacks theoretical grounding, its implementation is dictated by a set of best practices. A constructivist grounded theory approach was employed in an effort to establish a theoretical basis to guide the food assessment process. Steering committee members were invited to participate in a two stage interview process examining their experience and perceptions of the process. Existing ideological deviation amongst committee members plays a significant role in perception of work in the food system. In the context of the SRFA two general ideological positions were prominent, with members harbouring either a business or community food security orientation. These ideological underpinnings played a significant role in value associated with the process and its potential role in future action. This ideological deviation also had noticeable implications on the perception of other members. While the structure employed by this assessment was not conducive to promotion of high levels of engagement amongst the membership, participants indicating higher levels of value with the assessment process and its potential to facilitate subsequent action were more inclined to advocate for increased engagement. The food assessment process is growing in popularity and working towards a strong theoretical base is an important step. Establishing a deeper understanding of how the assessment process operates will allow it to be tailored to fit the needs of any given situation. This understanding will also facilitate an understanding of aspects required to provide the greatest level of value for participants involved in such short term collaborative efforts.

Climate change is taking its toll on Afghanistan. Warming temperatures and decreasing precipitation levels over the last fifty years have led to innumerable weather anomalies causing droughts, floods, unseasonal precipitation, falling ground water tables, desertification, and loss of biodiversity. While it is projected that further change in climatic conditions will take place over the coming decades, the impacts of these environmental stresses on the living conditions and livelihoods of Afghans have already been significant and adverse. Among all population groups, rural communities in Afghanistan are particularly vulnerable to the effects of climate change due to their strong dependence on agriculture for living. This exploratory research used a qualitative methodology to investigate and document firsthand the vulnerability of the rural communities to climate change impacts in the context of food security in Afghanistan. To this end, three villages in Balkh, Herat, and Nangarhar provinces were studied for their exposure to climate change and the communities’ adaptive capacity to cope with and avert the climate-related stresses. Additional key informant interviews were conducted to learn about similar issues in other rural regions of the country. The study found that climate change has substantially contributed to increased food insecurity in the rural communities throughout Afghanistan over the last two decades and that the rural households are facing real challenges to generate income from agricultural activities while taking desperate measures to cope with and adapt to climatic conditions.

Background: Food insecurity has been described as an urgent and pervasive public health issue for Aboriginal people (First Nations [FN], Métis, and Inuit) in Canada. However, national health surveys have generally excluded a large portion of the Aboriginal population (FN living on-reserve and Inuit), resulting in limited data on food insecurity in these individuals and communities. In addition, scales for measuring food insecurity have not been validated in Canadian Aboriginal populations. Food security challenges faced by Aboriginal people living in remote communities are unique and few studies have examined the perceptions of and coping strategies for food insecurity in this population. Objectives: The overall objective of this research was to explore various aspects of food insecurity (prevalence, perceptions, and coping strategies) in the remote, on-reserve First Nations community of Fort Albany, Ontario. This thesis consisted of five studies conducted in Fort Albany. The objectives for Study I were to quantitatively measure the prevalence of food insecurity using the Household Food Security Survey Module (HFSSM) and to use two qualitative interview questions to evaluate the relevance of the HFSSM. Study II used qualitative interview questions to examine the perceptions of and coping strategies for food insecurity. Studies III and IV investigated two programs in Fort Albany that had the potential to affect food security: the school snack program and a greenhouse project. Study III assessed the impact of the school snack program on student food intake. Study IV was a descriptive case study of the context and implementation of a community greenhouse project. Study V involved the development and formative evaluation of supplemental questions for the HFSSM intended to be relevant for measuring food security in First Nations households. Methods: One adult from each household in the community was invited to complete the 18-item HFSSM, demographic questions, and an interview with questions on the relevance of the HFSSM for First Nations food security and strategies used to cope with food insecurity. To evaluate the snack program, 24 hour diet recall data were collected using the Waterloo Web-based Eating Behaviour Questionnaire (WEB-Q) in November 2004 and December 2007 with grade six to 10 students attending Peetabeck Academy in Fort Albany. Food group consumption and nutrient intake of students participating in the school snack program were compared with students who chose not to participate. Five additional questions asked students about their participation, preferences, and impressions of the snack program. Data sources for the greenhouse project included semi-directed interviews with a purposive and snowball sample of community key informants, direct observations, written documentation, and photo-documentation. The case study was carried out over a period of 33 months; from early 2009 until October of 2011. The supplemental questions for the HFSSM were drafted based on themes that had emerged from the evaluation of the relevance of the HFSSM and relevant literature. Feedback on the importance, clarity, and cultural appropriateness of each proposed question was gathered from key informants (n=12) working on food security issues with Aboriginal groups, using an online survey. Results: For the HFSSM study, of 64 households (87% response), 70% were food insecure, 17% severely and 53% moderately. The prevalence of food insecurity in households with children was 76%. Among respondents from homes rated as having severe food insecurity, all (100%) reported worrying that food would run out; times when food didn’t last and there wasn’t money to buy more; and times when they couldn’t afford to eat balanced meals. When asked about the relevance of the HFSSM, the majority of respondents felt the HFSSM did not fully capture an accurate picture of food security for their situation. Aspects missing from the HFSSM included the high cost of market food and the incorporation of traditional food practices. For the coping strategies study, a thematic analysis of interviews (n=51) revealed that food sharing, especially with family, was regarded as one of the most significant ways to adapt to food shortages. The majority of participants reported consuming traditional food (wild meats) and suggested that hunting, preserving and storing traditional food has remained very important. However, numerous barriers to traditional food acquisition were mentioned. Other coping strategies included dietary change, rationing and changing food purchasing patterns. In order to improve access to healthy foods, improving income and food affordability, building community capacity and engagement, and community-level initiatives were suggested. Findings from the school snack program study showed that students participating in the snack program had significantly higher intakes from specific food groups and related nutrients compared to those who did not participate. With the exception of Meat and Alternatives in 2004, there was a trend for a higher percentage of students to meet dietary recommendations if they participated in the snack program. Students indicated that the three things they liked most about the school snack program were the juice, that the program kept them from feeling hungry at school, and that they got a snack at school every day. Students indicated that the snack program helped them to eat healthier by motivating them, eating more fruit, and making better dietary choices. Qualitative analysis of the greenhouse case study data generated gardening related themes: seasons, fertile ground, sustainability, gardeners, ownership, participant growth, and sunshine. Amongst the gardeners, local champions were critical to project success. Positive outcomes included the involvement of many community members, a host of related activities being carried out, and that the greenhouse had introduced an opportunity to gain knowledge about growing plants in a northern greenhouse setting. For the study on measuring food security in FN households, valuable feedback was provided by key informants (n=12) on clarifying the wording of the questions as well as providing perspectives on how the questions may or may not be applicable to different Aboriginal populations. A revised list of questions was created that incorporated the feedback from key informants. Conclusions: A very high prevalence of household food insecurity was reported in this community with the prevalence especially high in households with children. On-reserve remote FN communities may be more susceptible to food insecurity than off-reserve Aboriginal populations. Findings point to the continued importance of traditional food acquisition and food sharing, as well as community solutions for food systems change. These data highlight that traditional and store-bought food are both part of the strategies and solutions participants suggested for coping with food insecurity. Given the positive impact of the school snack program on the food and nutrient intake of student participants, it is clear that school snack programs can be an important venue to address the nutritional vulnerability of FN youth living in remote communities. Community and school greenhouse projects require local champions to be successful and foster community participation and ownership. Implementing a greenhouse project can engage community members, including children, and provide a great learning opportunity for gardeners in a remote, northern community. Finally, input from community participants and experts suggest additional questions that may add relevance to food security questionnaires for FN populations. Data highlight the urgency for public health policies and initiatives that promote food security for vulnerable FN populations. Findings can be used to inform assessment and program planning activities and to advocate for policies at the local, provincial and federal levels to strengthen community food security.
