Developing a method for regional food system planning in the Sea to Sky Region, British Columbia

Raimondi, Laura Joanne 08 May 2012 (has links)
This study set out to test the potential of an environmental management planning method to be adapted into a food system planning framework, referred to as a Regional Food System Management Plan (RFSMP). The RFSMP approach is a valuable and useful tool for regional food systems planning as it promotes community and environmental sustainability through enhanced food self-reliance. The RFSMP framework was developed and tested in the context of the Sea to Sky Region of British Columbia. The main components of the RFSMP framework included delineation of regional boundaries, stakeholder values identification and calculation of food self-reliance. Implementation of the RFSMP framework focused on the planning stage and the crop production components of the food system. This study recommends future work to address agricultural data gaps, complete the RFSMP framework beyond the planning phase and production component of the food system, and test the planning framework in other regions.

Analyzing Healthy, Local Food Systems: A Case Study of Owensboro, Kentucky

Hayden, Callie 01 January 2013 (has links)
Across the US, support is ever-growing for the local food movement. This growing trend promotes food security, supports farming families, ensures universal access to safe and healthy food products, enhances local economies, and encourages environmental and social well-being. People around the US are implementing sustainable local food systems as a means of meeting their individual community’s needs. While this movement is being popularized dramatically around the world, many cities and regions have yet to address it. This study reviews the existing literature on local food system models in an effort to answer the research question: What are the “ingredients” of a healthy local food system? The local food system of Owensboro, KY was analyzed via interviews with key players in its food system. In addition, experts in this field at the state level were also interviewed to understanding the functions of and the degree of support for local food systems in KY. Recommendations were then made for the city of Owensboro on how to further enhance its local food system into one of greater vibrancy and overall health.

How Trust in the Food System and in Brands Builds Consumer Confidence in Credence Attributes: A Structural Equation Model

2014 July 1900 (has links)
Given the credence nature of food quality and food safety attributes, consumers cannot easily verify whether food is high quality or is safe to eat, thus they rely on abstract systems of regulation and quality signals such as brands to make informed consumption choices. In fact, trust is recognized as a rational strategy that reduces consumers’ uncertainty when purchasing goods with credence attributes. While trust in food is a topical issue in an era of increasingly complex food systems, how trust and more precisely brand trust affects consumers’ perceptions of food is a relatively new research area in food economics. This thesis aims to answer questions such as what drives trust in the actors within the Canadian food system (i.e. government, farmers, food manufacturers, and food retailers) and in food brands, and the relationship between that trust and consumer confidence in food quality and food safety. Previous studies on institutional and system trust have been carried out primarily in the sociology, marketing and political sciences disciplines, while a few studies in food economics have investigated the influence of institutional trust and reported the degree of public trust in market actors. This study extends previous research on consumer trust in the context of food by developing a conceptual model in which trust in the food system and brand trust are expected to evolve to public confidence in credence attributes and lead to consumer commitment to food brands. Inspired from a comprehensive synthesis of the literature on consumer trust, the theoretical background suggests that consumer confidence in food attributes is jointly determined by trust in the food system (system-based trust) and brand trust (product-based trust), and it is moderated by consumer characteristics (personal-based trust) – namely: risk, past consumption experience and ethically-motivated behaviour. As well, consumers are assumed to perceive an actor or a brand as trustworthy through the influence of four postulated dimensions of trust: perceived competence, credibility, benevolence and reputation. A Structural Equation Modelling (SEM) approach is used for the empirical analysis. Data were gathered through an online survey of consumers conducted across Canada in July 2012 focusing on fresh chicken and packaged green salad products. The results show that individually none of the postulated antecedents of trust (i.e. competence, credibility, benevolence and reputation) was a significant driver for trust, especially for packaged salad. Unlike previous research on institutional trust and brand trust that uses a number of separate dimensions to measure trust predominantly in non-food contexts, this thesis finds that trust in the food system and food products could be measured differently by taking into account the interactive effects of perceived competence, credibility, reputation and benevolence on public trust. As such, the findings suggest that Canadian consumers tend to trust brands of chicken and packaged salad when these products are perceived as high quality, are backed by credible information, have a good reputation and, at the same time, enhance consumers’ welfare. In fact, a brand cannot be perceived as high quality and safe to eat (brand competence) without containing transparent information signalling its quality and safety (brand credibility). Additionally, results reveal some apparent product-specific effects: brand trust matters in fostering consumer confidence in chicken but not for salad. Furthermore, trust in the food system as a whole appears to be more influential in leading to public confidence in credence attributes than trust in food brands in the case of chicken. As such, it appears that trust in actors within the food supply chain is more important than relying on individual products. As well, the analysis shows that while psychographic variables (risk aversion, past consumption experience) and some demographics (e.g. gender, education) moderate the relationship between trust in the food system and brands for chicken, this is not the case for salad. In terms of marketing implications, the results suggest that while brands are useful signalling mechanisms, trust in these brands is not the main driver for consumer confidence in credence attributes. Furthermore, the much stronger effect of system trust implies that decision-makers would benefit by investing in building trust relationships with the public. Transparent communication and credible assurances about the practices and the intentions within the food system could be a way to gain and maintain public trust and, ultimately, consumer confidence in food quality and food safety.

Pathways to Resilience: Obstacles and Opportunities for Small-Scale Agriculture and Local Food Systems in British Columbia

Dell, W. Matthew 22 December 2015 (has links)
Climate change will impact food systems around the world by creating new ecological threats to crops and challenging the massive energy inputs required by modern industrial agriculture. The severity of these threats suggests that British Columbia's food system is unprepared for the adverse effects of climate change. The province currently produces 48% of its food requirements, much of which is allocated to export markets, and expansion of this system will be difficult as only 1% of provincial land is considered “prime” farmland. One way to prepare a food system for climate threats is to enhance the system’s resilience. A resilient system can quickly adapt to new external problems while maintaining its structure and productivity. A resilient food system is built on three important attributes: internal strength, diversity and flexibility. While there are numerous policy options to enhance resilience, this thesis focuses on role of small-scale agriculture and local food systems. This thesis will argue that provincial and local governments in British Columbia should pursue policies designed to expand small-scale food production and strengthen local food economies, as these scales of agriculture offer the most practical and politically feasible way to create a more resilient food system. To gather policy options that can achieve this goal, this thesis relies on ideas and insights gathered from sixteen interviews with a diverse group of small-scale farmers throughout B.C. These on-farm perspectives are then evaluated within the complex policy environment that impacts agriculture policy. Agriculture policy in B.C. is influenced by multiple variables, including established policies and financial investments that support large-scale and international agriculture, limited government budgets, challenging relations between provincial and local governments, and bureaucratic challenges with implementing and operating agriculture programs. Despite these challenges, there are numerous policy opportunities and partners that can help policies to support small-scale production succeed. This thesis analyses these obstacles and opportunities, and puts forward a comprehensive list of policy options organized by their political practicality. / Graduate / w.mattdell@gmail.com

Setting a Resilient Urban Table: Planning for Community Food Systems

January 2014 (has links)
abstract: Research indicates that projected increases in global urban populations are not adequately addressed by current food production and planning. In the U.S., insufficient access to food, or the inability to access enough food for an active, healthy life affects nearly 15% of the population. In the face of these challenges, how are urban planners and other food system professionals planning for more resilient food systems? The purpose of this qualitative case study is to understand the planning and policy resources and food system approaches that might have the ability to strengthen food systems, and ultimately, urban resiliency. It proposes that by understanding food system planning in this context, planning approaches can be developed to strengthen urban food systems. The study uses the conceptual framework of urban planning for food, new community food systems, urban resiliency, and the theory of Panarchy as a model for urban planning and creation of new community food systems. Panarchy theory proposes that entrenched, non-diverse systems can change and adapt, and this study proposes that some U.S. cities are doing just that by planning for new community food systems. It studied 16 U.S. cities considered to be leaders in sustainability practices, and conducted semi-structured interviews with professionals in three of those cities: Portland, OR; San Francisco, CA; and Seattle, WA. The study found that these cities are using innovative methods in food system work, with professionals from many different departments and disciplines bringing interdisciplinary approaches to food planning and policy. Supported by strong executive leadership, these cities are creating progressive urban agriculture zoning policies and other food system initiatives, and using innovative educational programs and events to engage citizens at all socio-economic levels. Food system departments are relatively new, plans and policies among the cities are not consistent, and they are faced with limited resources to adequately track food system-related data. However they are still moving forward with programming to increase food access and improve their food systems. Food-system resiliency is recognized as an important goal, but cities are in varying stages of development for resiliency planning. / Dissertation/Thesis / Ph.D. Environmental Design and Planning 2014

Food security and rapid urbanization : A case study of urban agriculture in Hanoi

Drebold, Helge January 2017 (has links)
As demand for food and farmland is increasing in Hanoi, the transition from an agricultural-based economy to an industrial one puts the livelihoods of urban farmers at risk. The urbanization displaces people and alter livelihoods of many urban poor in the peri-urban areas of Hanoi. This study uses the Sustainable Livelihood Approach in discussing the variety of chocks stakeholders associated with production, trading and consuming of vegetables, are exposed to. The findings provide a holistic perspective to the opportunities and constraints which urban agriculture is facing in modern day Hanoi. An outlining of urban agricultural production patterns according to the Von Thünen Model recognizing a slight alteration in which urban expansion hinders the production. Urban dwellers in peri-urban areas between a 5-15-kilometer radius from the city center are most vulnerable for land seizures and compensation rates are incused by corruption. Although there is potential for urban agriculture as demand for vegetables are high, the modernization of the country will continue to limit cultivation in the urban districts of Hanoi. Additionally, supermarkets with certified safe produced vegetables are currently in conflict with culturally embedded shopping practices. As public officials turn to the supermarketization to provide food safety, the rural-urban migration has shaped vegetable shopping differently.

The Inuit Food System: Ecological, Economic, and Environmental Dimensions of the Nutrition Transition

Kenny, Tiffannie January 2017 (has links)
From the Arctic to the South Pacific, Indigenous Peoples have experienced a rapid nutrition transition involving the decline of traditional/subsistence-based ways of life and the adoption of a “Western” diet that is high in saturated fats, sugar, and processed foods. This dietary shift has been paralleled by an increased prevalence of obesity, diabetes, and, other diet-related chronic diseases. In the Arctic, rapidly changing biophysical conditions, globalization, and integration into market economies are collectively challenging access to both country foods and nutritious market foods. Food security and nutrient adequacy thus remain elusive for Inuit communities of northern Canada. Premised upon the view that human well-being is predicated upon complex and dynamic interactions between ecosystems, economies, and societies, this dissertation integrates multiple lines of inquiry and scales of engagement (community, regional, and national) to further understanding of the nutrition transition among Inuit in Canada. The thesis is comprised of two sections. Section 1 bridges the often disparate fields of human nutrition and wildlife conservation by addressing key questions about the status and management of Arctic species, and the implications for Inuit food security and health. For example, caribou (Rangifer tarandus) populations across the circumpolar north are currently experiencing dramatic declines in abundance and restrictions on Inuit subsistence harvest are currently implemented for several caribou populations. Caribou, however, is the primary source of protein and several micronutrients involved in the prevention of anemia (e.g. iron zinc, copper, riboflavin, and vitamin B12) in the contemporary diet of Inuit adults. Caribou consumption is also positively associated with hemoglobin levels in Inuit adults. Section 2 considers elements of the market food system in Inuit communities. We found that the most popular market foods consumed by Inuit (e.g. sweetened beverages, added sugar, and bread) contribute significantly to total diet energy while contributing minimally to most micronutrients. Using optimization models, we have demonstrated that a nutritious diet (one meeting Health Canada dietary reference intake values) is theoretically feasible based on a mix of country food and market food, and at relatively little additional cost from current diets. However, significant deviations in patterns of food expenditure away from sweetened beverages, towards dairy, and whole fruits and vegetables would be required. Taken collectively, this thesis provides important information, as well as new tools, and approaches, for communities, wildlife conservation and public health professionals to jointly promote ecosystem and human health in a rapidly changing environment.

Hungry No More: A Food System Study & Hunger-Free Community Plan for San Luis Obispo County

Cadigan, Jenny 01 June 2012 (has links)
This project examines food systems and hunger in relation to city planning, and results in a draft strategic plan to address the food security and nutritional needs of San Luis Obispo County’s most vulnerable residents. This Draft Plan is submitted to the Food Bank Coalition of San Luis Obispo County as part of the Hunger-Free Community Project. The Food Bank Coalition of San Luis Obispo County was the lead agency of a USDA Hunger-Free Communities planning grant awarded in 2011. With this grant, the Food Bank convened a group of stakeholders to form the San Luis Obispo County Food System Coalition, and worked with community partners to conduct three studies on existing food resources, food security, and nutritional need in San Luis Obispo County. The outcome of this project is a draft of the third component of the grant – the creation of a strategic plan to address hunger and improve nutrition in San Luis Obispo County. San Luis Obispo County is a rural region rich in agricultural production, but hunger is a growing problem in the County indicating deficiencies in the local food system. One in six residents do not know where their next meal will come from. A high cost of living coupled with many low-wage jobs leaves many residents with few financial resources from which to provide food and other basic necessities. This project reviewed current professional and academic literature on food systems, hunger, and planning; conducted a case study analysis on existing hunger plans; compiled a background report on the existing hunger situation and community needs in the County; and worked with the San Luis Obispo County Food System Coalition to create the Draft Hunger-Free Community Plan for San Luis Obispo County. The Draft Plan and Background Report are organized into five themes: Food Access, Nutrition & Hunger, Local Agriculture, Community Resources and the SLO County Food System Coalition. As this plan is only a draft, the next steps that need to be taken before final adoption of the plan are outlined. This plan is a community plan; it will require the work and support of many organizations and agencies to effectively end hunger in the County.

Collaborative Logistics in Perishable Agri-Food Supply Systems

Francisco Munoz (12889766) 17 June 2022 (has links)
<p>  </p> <p>Managing agri-food supply systems (AFSS) is a complex task due to all the factors that are typically present in these systems, for example, perishability, long lead time from cultivation to consumption, seasonality, weather and yield uncertainty, fragmented structure of the industry, high demand- and price variability, contamination concerns, fragility, and high weight-to-value ratios. This research focuses specifically on crop-based perishable AFSS systems with independent farmers for which it is difficult to coordinate cultivation activities with upstream operations of the supply chain, and where it is not possible to decouple processing or distribution from harvesting operations by building on-farm inventory after harvest. Two main industries are considered as case studies: sugarcane and vegetables for the fresh market. In the sugarcane industry, two main problems are addressed in this research, the farms clustering and harvest sequencing problem, and the truck release control problem. The first problem is modeled as a bi-objective non-linear program that aims to maximize sugar output and minimize the maximum cluster diameter when clustering farms for harvesting, and a heuristic algorithm is developed to find a good set of non-dominated solutions. For the second problem, a stochastic model is developed to determine the optimal number of trucks to be released into the sugarcane harvest system considering randomness in key inputs. Finally, the third problem deals with the development of a demand and capacity sharing protocol to support horizontal collaboration among private distribution networks in the fresh vegetables industry based on a real-time truck-sharing system for the long-haul transport stage. The effectiveness of the protocol is tested by simulating its implementation to a collaborative network of six distributors, and the results show significant improvement in delivery times, long-haul transport costs, and total traveled distance.</p>

A sensory evaluation of swidden rye (Secale cereale) – how the taste of history and geographical location can play part in a sustainable food production

Jonsson, Amanda January 2022 (has links)
Due to their resilience, durability, and broad genetic variations, increasing the production and consumption of landrace cereals has been highlighted as a solution to handle increasing environmental variability resulting from climate change. However, the consumption of landrace cereals remains low due to limited production and purchase availability for consumers. To increase knowledge and possibly the production and consumption of landrace cereals, the overall aim of the study was to investigate the influence of terroir and the addition of ingredients on consumers' perception and acceptance of sensory qualities in cookies prepared from the landrace cereal swidden rye. Rye (Secale cereale) has been pointed out as a wonder crop and is of historical importance in the Nordic region. The study analyses the application of swidden rye (Swedish: Svedjeråg), a landrace variety of rye, in cookies by investigating how consumers perceive and describe its sensory characteristics. Additionally, the study explores how terroir relates to sensory perceptions. Five samples of swidden rye and a conventional rye sample have been included in the study. The study used a mixed methods approach with a Quantitative Descriptive Analysis (QDA®), a hedonic liking test, a focus group, and Geographical Information Systems (GIS) data. Different sensory profiles could be detected for the cookies produced with swidden rye, and a descriptive vocabulary and sensory profiles have been developed to describe the swidden rye cookies. Common descriptors were a browned butter aroma, a colour that ranged between golden and grey, roasted nutty and rye flavours, with a coarser or oily texture. All cookies were considered liked and acceptable by consumers, and cookies produced with swidden rye and the addition of butter and sugar could meet future consumers' expectations. There were relationships between terroir and sensory perceptions of swidden rye cookies. Relationships were found for increases and decreases in intensities of different sensory attributes. The geographical location on the latitude was only related to a decrease in the liking for texture; otherwise, differences in the consumer's liking were not related to the farm's geographical location. Showing that soil texture and land types are more related to differences in consumer liking and that the geographical location was less so. However, all parameters representing terroir were related to perceived sensory attribute intensities. The knowledge gained can be applied in the efforts to increase the production and consumption of landrace cereals. Communicating both the history, the historical importance, and the different sensory characteristics of swidden rye through terroir could be one way to increase consumers' interests and consumption.
