Recognizing the role of gender and food security in type 2 diabetes nutrition education in rural southwestern OntarioAppavoo, Donna January 2014 (has links)
Food systems and health systems are interdependent. Historically, however, strategies that focused on the development of these systems evolved in isolation from one another. Non-communicable diseases such as type 2 diabetes have an etiology that is strongly linked to food systems. Type 2 diabetes is taking an ever-increasing toll on health, and health systems, globally, and in Canada. In response, health professional organizations propose an advocacy approach to improve food system characteristics linked to the development of diabetes. Opportunities for, and barriers to, such initiatives have not yet been examined in the health geography literature.
The primary objective of this dissertation is to contribute to the development of a framework for action for nutrition educators working in rural areas to use to promote local sustainable food systems. The ultimate objective is to improve the diet, and by extension, the health of those suffering from type 2 diabetes. As part of the research approach, a gendered analysis was employed for the following reasons: First, labour around food production, food procurement and food preparation and health care work is provided predominantly by women. Second, there is a gendered profile of pattern of illness and access to care for people with type 2 diabetes.
The research methodology was comprised of a case study and mixed methods approach. Nineteen communities in southwestern Ontario were selected for inclusion in the case study using criteria based on the Rurality Index of Ontario. Data were collected through extensive literature reviews, 34 semi-structured interviews with health professionals, a survey of 24 people afflicted with type 2 diabetes and ‘in situ’ observations.
Analysis of the findings using grounded theory techniques, such as iterative coding, revealed barriers to, and opportunities for, supporting local sustainable food systems by area health professionals working at local, regional and national scales. This thesis provides important information about gender roles, community capacity, sense of community, and health professional training that should be considered in the development of policies to promote local sustainable food systems.

Charitable meal provisioning in Greater Victoria 2008-2011Bocskei, Elietha 20 September 2012 (has links)
Charitable food assistance programs such as food banks, food pantries, soup kitchens and community meals are the main food resource available to Canadians who are experiencing food insecurity. A survey was conducted with 48 agencies that operate food assistance programs in Greater Victoria, 30 of which were providing meals. In comparison to groceries or hampers, meals made up the majority of food relief available in the region. An exploration of the characteristics, resources and resource-related challenges of charitable meal programs provided insight as to how the food relief system operates, who is being served and the limitations facing agencies responding to food needs at the community-level. A comparison of meal provisioning in a selection of meal programs in 2011 to a similar survey conducted in 2008 found meal provisioning increased two-fold over this three year time span, all while agencies relied more on food donations and nearly half underwent major changes to their services mainly due to constrained resources. This study afforded the opportunity to discuss responsiveness of this system to food insecurity in Greater Victoria. / Graduate

Characterisation of a scum in sport drink and determination of the effects of preservation factors on its development.Mapompo, Odwa Mcebisi. January 2013 (has links)
The development of a scum in a commercial sports drink is of concern because the product
would be of poor quality, which may result in financial losses due to consumer rejection of
the product and hence a decrease in the firm’s market share. The scum could be harmful to
health and as such the firm could be litigated. Several factors, including microbial
proliferation, may be the cause of the development of a scum in sports drink, but the actual
cause seems not to have been established. The aim of this study was to characterise the scum
in sports drink and determine the effects of preservation factors (pasteurisation, chemical
preservatives and refrigeration) on its development.
Samples of the sports drink were taken at different stages of processing to determine the
effect of preservatives, pasteurisation and storage temperature on scum development. Some
samples were kept at room temperature (approx. 25°C) and others were kept in the
refrigerator (approx. 4ºC) during the study. A total of 150 samples were analysed over a
period of four months. The structural characteristics of the scum that developed in the sports
drink were determined by scanning electron microscopy (SEM) and elemental analysis. The
sports drink samples were analysed for their microbial load and microbial types. Consumer
acceptability of pasteurised and non-pasteurised drink was compared by conducting sensory
evaluation using a consumer panel of 60 panellists. Customer complaints recorded by the
sports drink manufacture that were due to scum development in the drink were also reviewed
to establish the impact of scum development on consumer acceptability of the drink.
The results of the study indicated that scum development was due to microbial contamination
of the drink. The causative organism of the scum was identified as Acinetobacter baumanii.
Acinetobacter baumanii is a gram negative non-spore forming coccobacilli and does not
ferment sucrose. Acinetobacter baumanii forms the scum in sports drink as a means of
protection from environmental stresses. The scum was found to be a compound of C, Si and
O. The non-pasteurised samples were slightly more acceptable to consumers compared to the pasteurised samples. The consumer acceptability of pasteurised drink samples was negatively
affected by the loss of aroma and flavour during pasteurisation. The preservation factors
(chemical preservatives, pasteurisation and refrigeration) had no effect on scum development.
To prevent post pasteurisation contamination, it is recommended that the pasteurisation
process be done at the filling stage instead of at the holding stage. The frequency of changing
rubbers and gaskets on the filling line should be at least every two months. The drink is
pasteurised at 90ºC for 20 seconds, this needs to be reduced to a level where it will not have
an influence on the loss of taste and aroma of the pasteurised drink, but without reducing the
effectiveness of pasteurisation. / Thesis (M.Sc.Agric.)-University of KwaZulu-Natal, Pietermaritzburg, 2013.

Application of Direct-sequencing Peptide Proteomics to the Characterization of Antagonistic (Endogenous and Exogenous) Proteins in Cereal GrainsKoziol, Adam 28 February 2013 (has links)
The cereal seed plays a crucial role in society – both in the “food as medicine” paradigm, but also in food security. It is the starch and proteins present in the seed that lend it importance in these dissimilar anthropomorphic activities. This thesis investigation first characterized the post-translational processing of the potential diabetogen, wheat globulin-3. Globulin-3-like peptides were observed primarily in the embryo. These peptides varied significantly in their molecular masses and isoelectric points, as determined by two dimensional electrophoresis and immunoblotting. Five major polypeptide spots were sequenced by mass spectrometry, allowing for the development of a model of the post-translational events contributing to the globulin-3 processing profile. Three separate investigations of starch granules from different cereal species were performed. In the first series of experiments, pathogen-susceptible maize kernels were injected with either conidia of the fungal pathogen Fusarium graminearum or sterile water controls. Proteins in the desiccated fungal remnants on the surface of the kernels as well as in the endosperm and embryo tissues of the control and infected kernels were isolated and these proteomes were sequenced using tandem mass spectrometry. Approximately 250 maize proteins were identified. These proteins were classified into functional categories. There was an increased representation of defense proteins in the both the embryo and endosperm tissues of infected maize samples. The proteome of the fungal remnants was composed of 18 proteins. Several of these proteins were categorized as being involved in the metabolism of plant-sourced molecules, or in stress response. The second series of experiments detail the investigation of commercially prepared rice and maize starches using tandem mass spectrometry. The majority of identified proteins, in both rice and maize samples, were involved in either carbohydrate metabolism or storage. Markers for seed maturity and for starch mobilization were also documented. Finally, the third series of experiments investigated the non-host proteomes present in commercially-prepared starches. Non-host proteins from a variety of species, including Homarus americanus were found in the starch samples. This documentation of H. americanus proteins in these starch samples may have food safety implications with regards to shellfish allergies.

The Effect of Climate Change on Food Security in Sub-Saharan AfricaLong, Shelby K 01 January 2015 (has links)
The purpose of this thesis is to examine the projected future changes in the global and Sub-Saharan Africa climate. These changes are expected to have varying effects depending on the region of the globe being examined. Sub-Saharan Africa is expected to be one of the most vulnerable regions in the future because of the already-variable and unpredictable climate. Population growth and lack of financial and informational resources further exacerbates the climate problems, making it even more difficult for African farmers to respond to their changing environment. In order to respond to these climate changes within an already dry and nutrient-lacking environment, farmers must be given the necessary adaptation information and aid from outside investors. However, without the proper information available to investors, regarding future expectations about precipitation, temperature, extreme weather events, soil nutrients, and available adaptation strategies, investors cannot efficiently allocate capital or other forms of aid. Therefore, I stress the importance of developing accurate climate models on a regional scale that investors can use to better allocate aid. Each region is affected in very different ways by the climate as a result of local topographical factors and global factors, such as the Intertropical Convergence Zone. Therefore, tools, such as models and simulations must be able to take these factors into account in order to accurately project future changes.
This thesis examines a wide range of existing literature in the area of climate change and food security on both a global and regional scale. I investigate the current and future climate of Sub-Saharan Africa, as well as the farming culture, in order to provide an in-depth understanding of the various factors that are interacting. Although many steps have been made to develop models and provide aid to Sub-Saharan Africa farmers, the lack of food security is only expected to become worse as the environment becomes harsher on food crops. Therefore, in order to respond to the expanding population and harsher farming environment, farming adaptations must continue to be intensified.

A Study of the impact of British Columbia’s meat inspection regulations and amendment on food security in select rural and remote communities in BCHodgson, Sally 13 September 2012 (has links)
Food safety regulations have increased over the past decade in response to food safety scares, international trade and changing public demands. The purpose of this thesis is to determine the impacts of meat safety regulations and a subsequent amendment on food security in rural and remote communities in British Columbia. Case studies of three communities, Bella Coola Valley, Haida Gwaii and Powell River Regional District, were utilized to assess these impacts. Interviews with government officials and local farmers were combined with agricultural and socio-economic data. Though it is not possible to attribute impacts directly and solely to the change in regulatory structure, it appears that the addition of harsh safety regulations has damaged an already fragile local meat industry in these vulnerable communities. The regulation amendment solved some of these issues, but many rural regions are still struggling to maintain local self-sufficiency in food production. / Graduate

Food gone foul: food safety and security tensionsMartin, Wanda Leigh 18 March 2014 (has links)
The purpose of this research is to examine how professionals and civil society members engage in food security activities that include food safety precautions and how they work across differences to support a safe and accessible food supply. The objectives are: (a) to explore tensions between those working in community food security and food safety (regulatory authority) and the source of tension; (b) to explore how people experiencing these tensions can improve the way they work together; and (c) to explore potential opportunities for enhancing health equity through food security and food safety programs. Using a case study design, I employ concept mapping and situational analysis as methods, with a complexity science framework. I have illustrated the complex motives behind food safety regulations and examined the neo-liberal agenda favouring market forces over health equity. I have argued that while there is concern for protecting the public’s health, food safety regulations are not set with a primary focus on protecting people from unsafe food, but are a vehicle for providing confidence in the market and among international trading partners, at the cost of health and welfare of small-scale producers in rural and remote communities. I am suggesting change not only in how we view and understand personal motives or worldviews of food and market forces, but also a shift on a larger scale, to change structural conditions to promote health and to encourage a moral obligation to reduce health inequities. / Graduate / 0573 / 0569 / wmartin@uvic.ca

Identifying land for community gardens in the City of Victoria: exploring the process of creating and conducting an urban agriculture land inventorySauter, Jennifer Anne 04 September 2014 (has links)
The City of Victoria is experiencing increased food insecurity due to its location on Vancouver Island in British Columbia, and a lack of food production in the city. The practice of urban agriculture presents a potential solution, enhancing food security by localizing resources, while increasing access and participation with local food production. Based on urban agriculture land inventories (UALIs) conducted in Portland, Vancouver and Nanaimo, my research evaluates and develops site selection criteria specific to Victoria for conducting a community garden land inventory focused on identifying land for allotment and commons gardens. I also examine the underlying barriers or supports for allotting land to urban agriculture in Victoria. To generate site selection criteria and explore the barriers and supports, I conducted interviews with urban agriculture experts, including city planners; community garden activists, educators and individuals involved in non-profits, and urban producers engaged in urban food production. The site selection criteria were further assessed as primary criteria for their application in GIS or secondary criteria to be considered during site visits. The final primary site selection criteria were land use and type, water availability (within 6.8 m), proximity to density users (within 400 m), minimum size thresholds of 1189.2 m2 for allotment gardens and 139.4 m2 for commons gardens, and excluding buildings, heritage designations, and protected green space. The analysis of the primary criteria resulted in a map illustrating 248 potential sites for community gardens in Victoria, whereby 213 were only suitable for commons gardens and 35 were suitable for allotment or commons gardens due to the larger size threshold. Four of the resulting sites were ground-truthed using site visits, and had medium to high potential for community gardens. The site visits documented secondary criteria, including proximity to community hub or prominent location, sunlight, ecologically sensitive area, cedar trees, and pollinator habitat or vegetation. Highlights from the interviews included identifying the most influential factors to allotting land to urban agriculture: the perception and awareness of urban agriculture, the community, the politics of City Council and staff support, and the costs or financial supports associated with community gardens. Overall, this research provides a model for the decision making process behind establishing an UALI, and contributes to understanding the challenges to allotting land to agriculture in the urban environment. / Graduate / 0768 / 0473 / jsauter@uvic.ca

Agroforestry Community Gardens as a Sustainable Import-Substitution Strategy for Enhancing Food Security in Remote First Nations of Subarctic Ontario, CanadaSpiegelaar, Nicole 25 April 2011 (has links)
The high prevalence of food insecurity experienced by remote First Nation (FN) communities partially results from dependence on an expensive import-based food system that typically lacks nutritional quality and further displaces traditional food systems. In the present study, the feasibility of import substitution by Agroforestry Community Gardens (AFCGs) as socio-ecologically and culturally sustainable means of enhancing food security was explored through a case study of Fort Albany First Nation (FAFN) in subarctic Ontario. Agroforestry is a diverse tree-crop or tree-livestock agricultural system that has enhanced food security in the developing world, as low input systems with high yields of diverse food and material products, and various ecological services.
Four study sites were selected for biophysical analysis: two Salix spp. (willow)-dominated AFCG test plots in an area proposed by the community; one “no tree” garden control test plot; and one undisturbed forest control test plot. Baseline data and a repeatable sampling design were established to initiate long-term studies on the productive capacity of willow AFCGs as a means to enhance food security in subarctic FN communities. Initial soil and vegetative analysis revealed a high capacity for all sites to support mixed produce with noted modifications, as well as potential competitive and beneficial willow-crop interactions.
Identification of barriers to food security and local food production in FAFN revealed a need for a locally-run Food Security Program (FSP) in partnership with the AFCGs to provide the personnel, knowledge and leadership necessary to increase local food autonomy and local food education and to manage the AFCG as a reliable food supply. Continued research on AFCGs and the FSP may allow wide-scale adoption of this strategy as an approach to enhance community food security and food sovereignty in remote FNs across Canada. An integration of conventional crops and native species in the AFCGs is recommended as a bicultural approach to enhance social, cultural and ecological resiliency of FN food systems. As an adaptable and dynamic system, AFCGs have potential to act as a more reliable local food system and a refuge for culturally significant plants in high-latitude FN socio-ecological systems, which are particularly vulnerable to rapid cultural and ecological change.
