In the United States, food banks served an estimated 46 million people in 2015. A combination of government policy reforms and political economic trends contributed to the rising numbers of individuals relying on private food assistance in the US, the United Kingdom and other high-income countries. Although researchers frequently map urban food environments, this project is one of the first to map private food assistance and potential need at the census-tract scale. We utilize Geographic Information Systems, demographic data, and food assistance locations to develop a rapid assessment tool that could support food banks, pantries, soup kitchens, and government agencies that seek to answer the question of whether people with the greatest need have food distribution sites in close proximity. We define access based on distance and then calculate potential food insecurity using either poverty rates or a food insecurity index. We apply these methods in a case study analysis of Santa Clara County, California. Our findings suggest that food assistance distribution locations match the areas of potential need in more than 80% of urban census tracts. However, there are several potentially underserved locations and populations that could benefit from new food assistance operations. The poverty and index-based approaches show significant spatial overlap in mapped areas of high food insecurity and low access. The poverty only approach produces a higher estimate of food insecurity rates, is easier to calculate, and draws attention to the need to address poverty as a root cause of hunger.  相似文献

This is a community based research project using a case study of 20 people living in middle America who are food insecure, but do not use food pantries. The participants’ rate of actual hunger is twice that of food insecure community members who use food pantries. Since most of the participants are not poor, the Asset Vulnerability Framework (AVF) is used to classify causes of food insecurity. The purpose of the study is to identify why participants are food insecure and why they do not use food pantries. Findings reveal that the participants restrict the quality and quantity of food eaten as a strategy to manage their budget. Following AVF, this strategy allows them to offset lower returns to labor assets, cover rising costs of human capital investment, protect their two most important productive assets of housing and transportation, and compensate for household relationships that increase their vulnerability. In addition, food insecurity itself inhibited social capital formation, further increasing vulnerability. The main reasons the participants do not use food pantries is to protect their social capital assets: almost all of the participants hid their hunger from colleagues, friends, relatives, and even the people they lived with. The participants described fear of societal shaming and blaming as motivations for hiding their hunger. However, using food pantries could reduce their food insecurity. Therefore, there was a feedback loop between food insecurity and social capital: food insecurity reduced social capital and efforts to protect social capital prevented participants from improving food security by using food pantries.  相似文献

The American food system has produced both abundance and food insecurity, with production and consumption dealt with as separate issues. The new approach of community food security (CFS) seeks to re-link production and consumption, with the goal of ensuring both an adequate and accessible food supply in the present and the future. In its focus on consumption, CFS has prioritized the needs of low-income people; in its focus on production, it emphasizes local and regional food systems. These objectives are not necessarily compatible and may even be contradictory. This article describes the approach of community food security and raises some questions about how the movement can meet its goals of simultaneously meeting the food needs of low-income people and developing local food systems. It explores the conceptual and political promise and pitfalls of local, community-based approaches to food security and examines alternative economic strategies such as urban agriculture and community-supported agriculture. It concludes that community food security efforts are important additions to, but not subsitutes for, a nonretractable governmental safety net that protects against food insecurity.  相似文献

This article argues that hunger in Canada, while being an outcome of unemployment, low incomes, and inadequate welfare, springs also from the failure to recognize and implement the human right to food. Food security has, however, largely been ignored by progressive social policy analysis. Barriers standing in the way of achieving food security include the increasing commodification of welfare and the corporatization of food, the depoliticization of hunger by governments and the voluntary sector, and, most particularly, the neglect by the federal and provincial governments of their obligations to guarantee the domestic right to food as expressed in international human rights law. The interconnectedness of hunger, welfare, and food security issues in a first world society are explored from the perspective of progressive social policy and food security analysis and the development of alternative strategies. In terms of advancing the human right to food in Canada, particular emphasis is placed on the role of the state and civil society, and the social and economic rights of citizenship built on an inclusive social policy analysis and politics of welfare, food security and human rights.  相似文献

Living in poverty is associated with high levels of protracted stress associated with health problems. Economic and food insecurity are particularly poignant aspects of poverty and condition the work of securing basic daily needs of families. Recent studies suggest that levels of stress increase as family food needs rise. This paper presents new findings which clarify the relationship of food provisioning to stress levels, by examining actual food provisioning strategies and food insecurity among the Northern Cheyenne Indians of southeastern Montana. Results clearly show that stress varies by types of food acquisition strategies. Contrary to our expectations, more complex strategies, including relatively unpredictable and cumbersome food provisioning activities, are not linked to higher stress levels in our analysis. Controlling for food security levels, households using a combination of local programs and informal subsistence sources are the least stressed, despite the demands of managing a large number of food sources. Households primarily using Food Stamps are the most likely to experience high levels of stress. Interviews with Food Stamp recipients show that potential sources of stress include inadequate allocations of Food Stamps, difficulty achieving and maintaining eligibility, challenges to complying with paperwork and appointment requirements, as well as personal obstacles and community barriers to making food stamps last. Analyses indicate that contradictions between local cultural norms for food provisioning and the realities of food insecurity in this context promote strategies emphasizing greater independence from federal food programs.  相似文献

Hunger in Canada     
Hunger is defined as the inability to obtain sufficient, nutritious, personally acceptable food through normal food channels or the uncertainty that one will be able to do so. After the depression of the 1930s, widespread concerns about hunger in Canada did not resurface until the recession of the early 1980s when the demand for food assistance rose dramatically. The development of an ad hoc charitable food distribution system ensued and by 1992, 2.1 million Canadians were receiving food assistance. In the absence of national monitoring systems, this remains the best available estimate of the prevalence of hunger. Hunger appears to be linked to poverty, unemployment, and numbers of people receiving social assistance. Although the Canadian social security system has traditionally been characterized by government-run universal and targeted programs designed to address income issues, hunger raises concerns about the current safety net. The primary response to hunger has been the proliferation of food banks, the agencies at the heart of the charitable food assistance system. On a smaller scale, community-based programs and advocacy initiatives have emerged. Nonetheless, the demand for food assistance continues to rise. The trend raises questions about future directions for social policy in Canada and concerns about the development of a two-tiered food distribution system—one for those with adequate money and one for the poor.Barbara Davis is the former Chair of The Canadian Dietetic AssociationAd Hoc Committee on Hunger, Editor of the Canadian Dietetic Association Nutrition and Food Security Network Newsletter, and Coordinator of the Masters in Health Science Program in Community Nutrition at the University of Toronto.  相似文献

Santa Barbara County exhibits some of the highest rates of food insecurity in California, as well as in the United States. Through ethnographic research of three low-income, predominantly Latino communities in Santa Barbara County, this study examined the degree to which households had been experiencing heightened levels of food insecurity since the economic recession and ensuing coping strategies, including gender-specific repercussions and coping strategies. Methods included administering a survey with 150 households and conducting observation and unstructured interviews at various local food-centered venues. Results indicated that households from the three communities were experiencing heightened levels of food insecurity and that all three communities were employing diversification of procurement, adjustments to a reduced or limited food budget, reliance on food assistance, and revitalization of the home as a site of domestic food production and preparation as coping strategies. The results also suggested that women suffered disproportionately higher psychological and physical costs associated with compounding crises. In conclusion, the experiences narrated by low-income households reflect a form of citizenship that appears compromised by a host of variables perceived to exist outside the realm of local control. Shifting toward an operational framework of food sovereignty may allow these communities to become more resilient in the face of future political, environmental, social, and economic stressors.  相似文献

In Canada, food assistance is provided through a widespread network of extra-governmental, community-based, charitable programs, popularly termed food banks. Most of the food they distribute has been donated by food producers, processors, and retailers or collected through appeals to the public. Some industry donations are of market quality, but many donations are surplus food that cannot be retailed. Drawing on insights from an ethnographic study of food bank work in southern Ontario, we examined how the structure and function of food banks operate to facilitate the distribution of foods not marketed through the retail system. Our findings indicate that the handling of industry donations of unsaleable products is a labor-intensive activity, made possible by the surfeit of unpaid labor in food banks, the neediness of food bank clients, and clients lack of rights in this system. The marshalling of volunteer labor to serve a corporate need might be construed as a win-win situation because the work of salvaging edible foodstuffs from among industry surplus helps to feed the hungry while also diminishing the amount of refuse deposited in landfill sites, sparing corporations disposal costs and landfill tipping fees, and helping them forge an image of good corporate citizenship. However, the reliance of food banks on industry donations means that food assistance becomes defined as that which the corporate sector cannot retail. Moreover, the intertwining of food bank work with corporate needs may function to further entrench this ad hoc secondary food system and mitigate against initiatives to develop more effective responses to problems of hunger and food insecurity in our communities.  相似文献

Dumpster diving is a term generally used for obtaining items, in this case food for consumption, from dumpsters. This study evaluates the prevalence of dumpster diving in two low-income urban communities in Minneapolis, Minnesota. Additionally, attitudes and beliefs of adults who engage in this behavior are reported. Surveys (n=396) were used to collect data including individual dumpster diving behavior, food security, health, and demographic data. Nearly one-fifth of those surveyed had used dumpster diving as a means to obtain food. Focus groups (n=17) were conducted to further evaluate dumpster divers attitudes and beliefs about dumpster diving, use of food assistance programs including benefits and barriers, and other strategies used to obtain food such as stealing. Focus group participants were primarily homeless and most were high school educated. Ways to improve delivery of food assistance are suggested. In conclusion, more research on the use of dumpsters as a source of food is needed. Utilizing more of the 96 billion pounds of food wasted each year in the US through food recovery and donation programs could help to provide socially acceptable means for low-income urban dwellers to obtain food.  相似文献

This paper explores conceptual and practical linkages between women and food, and argues that food security cannot be realized until women are centrally included in policy discussions about food. Women's special relationship with food is culturally constructed and not a natural division of labor. Women's identity and sense of self is often based on their ability to feed their families and others; food insecurity denies them this right. Thus the interpretation of food as a human right requires that food issues be analyzed from a gender perspective. For example, the paper asks how the rights to food intersect with the rights of women and other human rights; what the policy implications of these intersecting rights are; and how their integration will contribute to the effort to view all human rights as mutually reinforcing, universal, and indivisible. The second half of the paper speculates on the significance of distinctions between the right to be fed, the right to food, and the right to feed for understanding the relation between gender and food.  相似文献
