Increasing globalization of the food system has led to a loss of food sovereignty and security in communities throughout the world. This globalized system has adopted industrial techniques of standardization and specialization as the solution to producing an abundant cheap food supply. Over time this system has become concentrated in the hands of a few transnational corporations that increasingly control every step of production from farm inputs, to distributing and processing. As a result, we have experienced the emergence of a counter movement to the corporate controlled and globally sourced dominant food system we have today. The rise of local food systems in industrialized countries developed to help solve the issues created by the current food system. This study provides insight into the barriers and opportunities to the development of local food systems, as well as the universality of these barriers. To achieve this, a multi-case study was conducted in Nelson, British Columbia; Lethbridge, Alberta; and Waterloo, Ontario. In each of these locations information was consolidated from food 'experts' or key informants, consumers, farmers, and supermarket owners/managers. Research methods included semi-structured interviews, a consumer survey, interpretation of government documents, and study site observation. Results from this study add to the empirical work on local food systems in Canada and offer a multi-stakeholder perspective of the barriers and opportunities to localization efforts. Findings suggest that the barriers to the development of local food systems are largely universal and are supportive of other empirical and theoretical works. Barriers included issues such as federal agricultural policy, health and safety regulations, consolidation of food retailing, and a demand for cheap food. The opportunities for a local food system, although more diverse and different between regions, can all for the most part be universally applied. While many opportunities exist for municipalities to enhance local food in their region, barriers created by government and industry will ultimately limit any notable movement toward a more localized food system without more significant policy changes from above. This study supports the idea that local food systems will require government assistance in order for changes from the grassroots to make significant strides in becoming less dependent on food imports.

The killing effectiveness of electron beam irradiation has not been completely characterized. The type of microorganisms and the composition of food have a direct effect on the efficiency of this technology. The objectives of this study were to select a surrogate suitable for use in electron beam irradiation studies of fruits and to evaluate the effect of sugar content on the kinetics of microbial damage and recovery. A 2.0 MeV Van de Graaff linear accelerator was used to apply irradiation (up to 5.0 kGy), using different configurations, on gelatin-based systems with the addition of sugars. The systems were inoculated with pathogenic and non-pathogenic bacteria strains (surrogates). Initial studies showed that Escherichia coli K-12 MG1655 is a suitable surrogate that represents the damage induced to common fruit pathogens by irradiation. The reduction in bacteria population can be maintained by storing samples at 4°C. An increase in temperature up to 20°C was enough for the damaged population to recover in 48 hours. Gelatin-based systems proved to be a simple and inexpensive medium to evaluate the effects of irradiation (up to 5.0 kGy) on selected bacteria. Reduction of the system dimensions and their positioning related to the beam source were key factors in increasing the killing effectiveness of irradiation. The sugar levels (up to 8 %) used to mimic the maturity of cantaloupes had no effect on the radiation D10 values and the recovery of the surrogate population quantified as Generation Times. The resistance of the surrogate to irradiation was validated in an optimum configuration and in cantaloupes. Temperature and sugar content caused significantly higher changes to the physical structure of the gel-based systems than irradiation (1.0 kGy). Plate counts and light microscopy techniques demonstrated that the structure of the gelatin-based systems allow for motility of the bacteria in a 3-D array (length, width and depth). When little information was available about the effectiveness of using a low energy linear accelerator, the inoculation of gelatin-based systems proved to be a reliable method to select a suitable surrogate and to predict the effects of irradiation on bacteria as a function of sugar content.

This thesis seeks to explore the impact that architecture can have on peoples' relationship with food. The industrialization of American society over the past two centuries has distance people from the source of their food; this distance has significantly contributed to an overall decreased in American health. The concept of this thesis is that architecture can have a positive impact on peoples' relationship with food and thereby help improve the health of a community. I chose a site on the outskirts of Glens Falls, New York to locate my project, the Glens Falls Good Foods Collective. This site is ideal for bringing people and food together as a few miles to the West lays the city center, while abundant farmlands fan out toward the East. The Collective combines small-scale food processing facilities for farmers with a market place for consumers. Providing an environment in which these ever-distancing demographics can interact would help reduce the gap between people and food. The goal of this thesis is to design a building that fosters a meaningful and productive connection to food by bringing people closer to its source.

Historical contexts of trauma have created a complex relationship with African Americans and farming. Further, the lack of urban participation within the food system has resulted in little knowledge of how food is produced or understanding of environmental impacts of food and fiber production. The only participation has been the consumption of food. This study indicated the importance of exposing normalized food system inequalities and fostering critical consciousness to challenge systems of oppression. Further, this study alludes to returning to the food system and reimagining taking control of the food system through a reconnection to the land as a form of resistance, protest, and liberation from oppressive systems. The school system is failing to teach about the inequalities of the food system and how youth can participate in the food system. To address disparities in education, education should be more relevant to the student population. In order to make progress toward connecting the food system and urban minority youth, new methods should be implemented to engage and connect. After-school and non-formal spaces are innovative educational opportunities to address these problems. This study was guided by critical pedagogy that challenges the current social order and culturally relevant pedagogy's cultural relevance. To break away from the oppressive banking system, students must acquire a critical awareness of the systems of oppression and confront reality critically by recognizing its causes, which will require breaking away from oppressive guidelines and the freedom of autonomy and responsibility. To assess minority youth conceptions of the food system through a hip-hop based learning curriculum, the researcher selected a group of seven students from an after-school program in Roanoke, Virginia, to participate in the workshop. The qualitative case study consisted of one workshop a week for two weeks, followed by an initial focus group. Two workshop groups were conducted after and were followed by a concluding focus group. Data sources included researcher field notes and focus group transcripts. Transcripts were analyzed using two cycles with field notes utilized for triangulation of findings. In the first coding cycle, descriptive coding paired with emotion coding was used. The second cycle of coding consisted of axial coding and then codes were consolidated by matching like codes grouped by similar categories. Finally, the researcher developed themes based on the research literature, research questions, and conceptual framework. Findings of this study include the importance of exposing normalized food system inequalities and fostering critical consciousness to challenge systems of oppression. Further, this study expressed that youth are engaged in hip-hop culture and creating culturally relevant spaces for youth allows for participation and connection that other after-school programs cannot provide. Participants presented a change in conception and developed an emerging critical viewpoint to the once-normalized systems of food access. Lastly, participants expressed interest in developing the local community and improving healthy food access. / Master of Science in Life Sciences / Creating educational spaces that support the cultural context of youth is a growing concern. Disconnection from the traditional classroom has led education researchers and practitioners to explore ways to connect minority students to the learning environment. The concern of the modern education system and its deficit in supporting minority populations has called for implementing new strategies. Outside of the classroom, non-traditional spaces have become spaces of creativity. Historical disconnection and historical trauma from agriculture has resulted in the population of minorities becoming passive recipients of an unequal food system. In order to assess the importance of exposing normalized food system inequalities and fostering critical consciousness within minority youth, a culturally relevant program was used to explore minority youth conceptions of the food system and explore their change in conceptions. Youth participated in a four-week, hip-hop-based workshop to explore the food system. This workshop challenged their perceived understanding of their local food system and the hidden inequalities within it. The findings of this study indicated the importance of exposing normalized food system inequalities and fostering critical consciousness within minority youth. Participants presented a change in their conception of the food system. Further, participants expressed emerging socio-political awareness of food access. This research study contributes to the work of culturally relevant education, the development of youth critical consciousness, awareness, and community development.

Food system is complex and encompasses stakeholders from local, regional, and global level. The activities and outcomes of the food system are associated with environmental, economic, and social impacts. Due to the growing population, and urbanization, along with the fact that global food system contributes up to 30% of anthropogenic GHG emission, one of the main contributors to climate change, a sustainable food system that could meet the food demand in the urban areas is in need. Therefore, high-tech urban agriculture (HTUA) that uses advanced technologies and enables food production in a controlled environment is seen as a promising solution, which remains niche in Sweden. This study adopted the sustainable food system approach and used the theory of multi-level perspective (MLP) on sustainability transitions to explore this technology-driven transition and identify the challenges and opportunities in developing HTUA in Sweden. Through the analysis of five Swedish policy documents and interviews with four HTUA initiatives in Stockholm, three main aspects are identified: 1) external context; 2) policy environment; and 3) communication and influence, which are independent but also interconnected. According to the findings, the global environment and Swedish context, such as climatic condition and Swedish consumption, provide HTUA an opportunity to develop. The findings also suggest that though the characteristics of HTUA initiatives and the priorities within the Swedish policy environment have overlapping traits, the policies are not effectively translated into practice and thus making it challengeable to develop HTUA in the long run. Implementing more strict restrictions and regulations on the external price, providing an easier access to urban space, simplifying the procedure for the financial support, raising public awareness towards HTUA, and bridging the knowledge gap among all stakeholders through collaborations and partnerships are suggested to reduce the risk of initiating HTUA. However, further research is still required to understand the potential of HTUA in the transformation towards a sustainable food system.

This thesis examines the enduring problem of food insecurity in Africa, with a particular focus on Ethiopia and Kenya. It considers food insecurity both in acute terms - the occurrence of famine and chronic terms - famine vulnerability. More specifically it provides a new interpre~tion of the causes of food insecurity in East Africa, with respect to some of the causal factors and viable solutions. It does so by locating the occurrence of famine, and countries vulnerability to it, in the context of the global food system. The global food system is, as yet, an under-examined factor in contemporary famine analysis, particularly in East Africa and this thesis aims to explore it more comprehensively than hitherto. This thesis also makes a substantive contribution to understanding the concept of Food Sovereignty in an African context. Food Sovereignty deserves to be a more significant part of contemporary narratives that at present dominate the political and social dilemmas about food insecurity. However there are serious obstacles such as political relationships, land tenure and the industrial system of agriculture that hinder the development of Food Sovereignty as a viable option. Natural disasters, demographic pressures and ill conceived economic policies are an ongoing part of the story but in essence food insecurity is ultimately political. This thesis concludes that Food Sovereignty should be explored as a political . solution to a political problem.

This thesis examines the feasibility of fostering “sustainable foodscapes” in urban communities. A review of the literature on the topics of sustainability, resilience, sustainable food security, and healthy communities is used to determine to the definition of “sustainable foodscapes.” This thesis uses a framework of socio-ecological restoration to consider how communities might adopt sustainable foodscapes. A case study is conducted in the city of Waterloo, Ontario to test the criteria of sustainable foodscapes and explore some of the practical opportunities and barriers to developing sustainable foodscapes in an urban community. The methods for the case study include semi-structured interviews. Interview results indicate that a variety of sustainable foodscapes such as community gardening, individual gardening, and foraging are used in Waterloo already, and survey results suggest that various members of the community are open to the adoption of these foodscapes. The case study results reveal that diverse community members view sustainable foodscapes as an important contribution to community health, less for the purpose of ecological sustainability than for their usefulness as a way of promoting community interaction, social learning, and fostering a sense of place. Ways to conduct a socio-ecological restoration for sustainable foodscapes in Waterloo could include increasing areas for the purposes of foraging to occur in an ecologically benign manner, such as on marginal or private land; creating municipal policies and Official Plans that provide support for community gardens, and fostering more accepting attitudes towards sustainable foodscapes by providing increased opportunities for education and participation among community members.
