In this paper we critically examine mobile markets as an emerging approach to serving communities with limited healthy food options. Mobile markets are essentially farm stands on wheels, bringing fresh fruits, vegetables and other food staples into neighborhoods, especially those lacking traditional, full service grocery stores, or where a significant proportion of the population lacks transportation to grocery stores. We first trace the emergence of contemporary mobile markets, including a brief summary about how and where they operate, what they aim to achieve, who they serve, and the general constraints on their operations. We then report case study findings that examine the operational benefits and challenges of two mobile markets operating in Syracuse, New York. Our research suggests that although Syracuse’s mobile markets play a positive role in alleviating geographic, economic and social barriers to fresh food access experienced by elderly, immobile and low income residents living in Syracuse’s urban neighborhoods, the impacts of the mobile markets are dampened by both operational constraints and larger political and economic forces.  相似文献

The contemporary US food systemis characterized by both an unprecedentedconcentration of corporate control as well as afragmentation of sourcing and marketingprocesses, introducing both new constraints andnew opportunities for more localized foodsystems. The purpose of our study is to explorethese issues by investigating three keyquestions. First, what are the key trends inthe US grocery industry? Second, how dodifferent kinds of food outlets choose,procure, and promote food products? Finally,what are the implications of recent trends inthe food retailing process for strengtheninglocal flows of the production, distribution,and consumption of food? Background informationon the grocery industry and the results ofseven open-ended interviews conducted withowners and managers of grocery stores in oneupstate New York county indicate that theretailing process differs in complex ways fromstore to store and in most aspects cannot beinferred from store type. The paper concludeswith a discussion of the implications of ourfindings for local food system efforts,specifically in terms of new collaborationsamong producers, distributors, retailers, andshoppers, who play an indispensable role indeveloping viable alternatives to increasingcorporate control.  相似文献

Access to fruits and vegetables by low-income residents living in selected urban and rural Minnesotan communities was investigated. Communities were selected based on higher than state average poverty rates, limited access to grocery stores, and urban influence codes (USDA ERS codes). Four communities, two urban and two rural, were selected. Data were gathered from focus group discussions (n = 41), responses to a consumer survey (n = 396 in urban neighborhoods and n = 400 in rural communities), and an inventory of foodstuffs available at stores located in all the communities and at large grocery stores in neighborhoods adjacent to the urban communities. In the two urban neighborhoods, a significant number of foods (26% and 52%) were significantly more expensive than the Thrifty Food Plan’s (TFP) market basket price (MBP). Additionally, a significant number of foods in the two rural communities were more expensive (11% and 26%). In focus groups, participants identified major barriers to shopping in their community to be cost, quality of food, and food choice limitations. Results of the food inventory show that foods within the communities were costly, of fair or poor quality, and limited in number and type available, supporting complaints verbalized by focus group participants. Through focus groups and surveys, participants expressed concern that healthy food choices were not affordable within their communities and believed that people in their community suffered from food insecurity. The absence of quality, affordable food for low-income residents in these four Minnesota communities prevents or diminishes their ability to choose foods that help maintain a healthy lifestyle.

Qualitative and quantitative methods were used to investigate how shopping behaviors and environment influence dietary intake and weight status among homeless Minnesotans living in food deserts. Seven focus groups (n = 53) and a quantitative survey (n = 255), using the social cognitive theory as the theoretical framework, were conducted at two homeless shelters (S1 and S2) in the Twin Cities area. Heights, weights, and 24-h dietary recalls were also collected. Food stores within a five-block radius of the shelters were evaluated for the price and availability of foods and compared to the Thrifty Food Plan’s market basket prices (MBP). Results showed that almost 80% of the sample was overweight or obese, with women consuming less than the recommended level for the fruits, vegetables, and milk food groups and excess for the fats/oils/sweets food group. Focus groups and participant surveys indicated that the shelter infrastructure and surrounding community influenced the types of foods available, food store access, and the foods purchased and consumed. Participants relied on food assistance programs, including food stamps, to supplement their food supply; however, some felt the high food prices at neighboring stores limited food choice and that food stamps did not adequately cover food costs. Results from the food store survey found the majority of food prices exceeded Midwest or national MBP. To promote healthier dietary intake and weight status, community-based interventions and city planners should aim to increase access to food through improved food availability and food access within the shelter environment and surrounding community.  相似文献

Food security is a fundamental element of community health. Informal house-lot food growing, by providing convenient access to diverse varieties of affordable and nutritious produce, can provide an important support for community food security. In this exploratory assessment of the contribution home food gardening makes to community food security, in-depth interviews were conducted with gardeners in two contrasting neighborhoods in Toronto, Canada. A typology of food gardeners was developed, and this qualitative understanding of residential food production was then assessed from a community food security perspective. It was found that growing food contributes to food security at all income levels by encouraging a more nutritious diet. The sustainability of household food sourcing and gardeners?? overall health and well-being also increased with food production. Secure access to suitable land to grow food and gardening skills were the most significant barriers found to residential food production.  相似文献

Reciprocity and redistribution economies are often used by low-income households to increase access to food, adequate diets, and food security. A United States study of two high poverty rural counties and two low-income urban neighborhoods reveal poor urban households are more likely to access food through the redistribution economy than poor rural households. Reciprocal nonmarket food exchanges occur more frequently in low-income rural households studied compared to low-income urban ones. The rural low-income purposeful sample was significantly more likely to give food to family, friends, and neighbors and obtain food such as fish, meat, and garden produce from friends and family compared to the urban low-income group. Further, 58% of the low-income rural group had access to garden produce while only 23% of the low-income urban group reported access. In a rural random sample of the whole population in the two high poverty counties access to garden produce increased chances of attaining recommended vegetable and fruit servings controlling for income, education, and age. Access to a garden also significantly increased the variety of fruits and vegetables in diets.

Participation in the local food movement has grown dramatically in the United States, with the farmers’ market being one of its most widespread and heavily promoted forums. Proponents argue that the interactions and transactions that occur at farmers’ markets benefit market participants, but, more importantly, have broader benefits for the neighborhoods they are located in and for society itself. The promise of these benefits raises several important questions, notably: where are farmers’ markets located and who has access to them? While many works have examined the characteristics of individuals who frequent markets, few have examined the areas and inhabitants hosting these markets. Using data from the USDA and US Census, I explore the location of farmers’ markets areas across several geographic measurements, including at the national, census division, and census tract levels. Results reveal the following: (1) Perhaps not being as white of a movement as critics have suggested, farmers’ markets are almost exclusively a middle to middle-upper class phenomenon; and (2) Farmers’ markets are very unlikely to be found in neighborhoods with lower than average socio-economic statuses indicators, in specific divisions of the US, and in rural areas. Results from this research further illuminate our understanding of where farmers’ markets are located throughout United States while presenting some interesting questions for the local food movement as it continues to moves forward.  相似文献

Local foodshed proponents in the United States seek to change the food system through campaigns to “buy local” and to rediscover “good food” in the local foodshed. Presumably, common sense dictates that the word “local” signifies spatial proximity to the consumer. For some populations, however, both the terms “local” and “local food” signify various different meanings. The local food definition generally used by scholars and activists alike as “geographically proximate food” is unhelpfully narrow. Localist rhetoric often does not incorporate the food choices and practices of immigrants, migrants, and refugees. In this paper, I report the various characterizations of local food among Filipino immigrants in San Diego, California: (1) geography-based local food; (2) (US) America-based local food; (3) community-based local food; and (4) immigrant identity-based local food. Local foodshed proponents should acknowledge those who have a starkly different definition of “local”—those who possess translocal subjectivities, for whom “local-ness” is both mobile and embodied. My study underscores how the movement of food—or its containment within a geographic space—cannot be viewed in isolation from the movement of people.  相似文献

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 paper provides a conceptual framework to explain why disparities may exist in food safety code compliance by food stores in different neighborhoods. Explanations include market dynamics, community characteristics, retailer attributes, inspector characteristics, and enforcement approaches, and interactions among the factors. A preliminary and limited empirical test of some of these relationships in Detroit, Michigan shows a higher rate of food safety violations by stores in poorer neighborhoods and in neighborhoods with higher concentrations of African-American residents. Stores inspected by female inspectors also scored higher numbers of critical violations, suggesting a need for greater examination of the social relations associated with enforcement interactions in food safety studies.

Much of the developing world, including Kenya, is rapidly urbanizing. Rising food and fuel prices in recent years have put the food security of the urban poor in a precarious position. In cities worldwide, urban agriculture helps some poor people gain access to food, but urban agriculture is less common in densely populated slums that lack space. In the Kibera slums of Nairobi, Kenya, households have recently begun a new form of urban agriculture called sack gardening in which vegetables such as kale and Swiss chard are planted into large sacks filled with topsoil. This paper examines relationships among sack gardening, social capital, and food security in Kibera. We used a mixed methods approach, combining qualitative interviews with a household survey, as well as focus group discussions with both farmers and non-farmers. We present evidence that sack gardening increases social capital, especially for those households that undertake sack gardening in groups. We also find that sack gardening in the Kibera slums has a positive impact on household food security by improving household dietary diversity and by reducing the need to resort to painful coping mechanisms that are used during food shortages.  相似文献
