Can Anyone with Low Income Be Food Secure?: Mitigating Food Insecurity among Low Income Households with Children in the Tampa Bay Area

Amador, Edgar Allan 05 July 2014 (has links)
In the US over the last few years, approximately 14.5% of households experience food insecurity at some point throughout the year. While studies on food insecurity in the US have determined that household income and specifically income available to spend on food is of critical importance to food security, it is still unclear why some households with low income are able to maintain food security while others experience food insecurity in a pattern characterized as not constant but recurrent. This dissertation compares households with children at different levels of food security and insecurity using the USDA Core Food Security Module (CFSM) and an ethnographically informed analysis of coping in order to understand the differences between at-risk households in order to determine why some fall into more severe food insecurity while other manage to avoid it. Data on food security, demographics, use of food assistance programs, shared cultural models for food, food shopping behavior, food consumption, and measures of depression and anxiety were collected from 207 households. Households at or below 185% of poverty line (n=106) were grouped by food security status--food secure (FS), low food security (LFS), and very low food security (VLFS)--into three groups. The remaining households (n=101) were used as an out-group for comparison. The results revealed that for low income households (below 185% of poverty line) income was not a significant factor for many of the comparisons between FS and LFS or VLFS households. Instead, other variables such as higher stress index score (PSS), younger age of respondent or food procurer, and the presence of a spouse or partner were more important predictors of food insecurity. Households used safety net resources to cope with food insecurity, though as predicted by the literature these resources where used to mitigate food insecurity as opposed to buffer against it. Finally, there were large and significant differences between the three groups in the amount of stress (PSS) and depression (HSCL-10) symptoms measured in the respondents, affirming the relationship between food insecurity and stress that has been documented in the literature. The study concludes by recommending that future research explore the way in which food insecurity and stress affect household relationships because (1) living with a spouse or partner predicted food insecurity in this sample of at-risk low income households and (2) there was some evidence that male food procurers experience more stress than female food procurers.

Trade Liberalization and Food Security : The Case of Bolivia after the Structural Reforms of 1985

Valencia Amaya, Mauricio Giovanni January 2009 (has links)
<p>This research shows the relationship between trade liberalization and food security for the Bolivian case. As a result of the severe economic crisis of the early-1980s, Bolivia adopted a series of market-oriented reforms in 1985. The reforms included the liberalization of the trade regime and the promotion of non-traditional exports. The trade liberalization had an important effect on the performance of cash crops, especially in the development of the soybeans industry. However, foodcrops did not have such a great dynamics. Vegetables and starchy roots declined in per capita terms and the increase in imports were not enough to compensate the decline. Trade reforms mostly favor a small group of large-scale farmers in the lowlands, who had historically been granted land in the region. In this sense, Bolivia’s involvement in a trade liberalization process was not reflected in an overall improvement of the country’s food security.</p>

An Assessment of Food Security Interventions for People Living with HIV/AIDS on Antiretroviral Treatment at Household Level in the Khomas Region, Namibia.

Magazi, Shirly. January 2008 (has links)
<p>In the era of AIDS, food and nutrition are becoming more of a priority for many households and communities. This is more so now that treatment is available for people infected with HIV and AIDS. Food and nutrition are fundamentally intertwined with HIV transmission and the impacts of AIDS. Evidence of the ways in which food insecurity and malnutrition may interfere with the effectiveness of antiretroviral therapy is well documented. Aim: The purpose of the study was to inform improvements in food security interventions for PLWHA through an investigation of existing food security interventions in the Khomas Region, Namibia.</p>

A Comparative SWOT Analysis of the National Agricultural Extension Program Organization to Determine Best-Fit Program Model: A Case Study of the North West and South West Regions of Cameroon.

Nyambi, Gwendoline 2012 May 1900 (has links)
Agriculture is crucial to the economic and social wellbeing of the Republic of Cameroon. A national need for increased productivity, farm incomes, food security and rural development requires more effective agricultural extension and advisory systems. The need is persistent. This study analyzed strengths, weaknesses, opportunities, and threats that existed within the current national extension program and examined how form, function, and policy influenced two regions in Cameroon. Analysis focused on 15-year time changes using a comparative case study design. Four regional focus groups and 28 individual interviews bounded 59 cases from four stakeholder groups of farmer leaders, non-governmental organizations, extension representatives, and governmental counterparts. Eighteen primary themes emerged with overlap of opportunities and threats among stakeholders. Incentives to program performance included staff competence and innovative technology transfer. Barriers included infrastructure, postharvest technology, market incentives, financial sustainability, and feedback. A lack of vision for sustainability, inadequate government funding, poor collaboration and linkages, uncoordinated parallel programs, and ineffective management systems reduced program potential. Four themes framed recommendations for improved programs: government investment, trainings, market incentives, and management. Options to improve program sustainability included subsidies that benefit all farmers, more council and private sector engagement with extension, rural infrastructure development, price standardization, and fees for service. Medium and large-scale farmers were willing to pay for extension services when and if available whereas small-scale farmers relied heavily on subsidized services. Accessibility to markets, farm size, and cash crop production are associated with farmers’ acceptance of fees for service. These findings highlighted areas where changes in the nation’s agricultural extension service could improve its relevance in meeting performance targets. Stakeholders’ recommendations for more effective agricultural extension and advisory systems included: 1) providing an autonomous extension service that focuses on specific needs and market opportunities and coordinates all support/parallel programs while collaborating among research and private advisory services; 2) implementing holistic government policies that integrate technology transfer, innovation, health, value-chains, and markets to benefit all farmers; 3) redesigning subsidies that equitability incentivize production and sound environmental practices that benefit all farmers; 4) increasing in-service trainings related to innovations; and 5) updating innovations and harmonizing program activities.

Food Related Activities and Food Intake in Everyday Life among People with Intellectual Disabilities

Adolfsson, Päivi January 2010 (has links)
The aim of this thesis was to study food, eating and meals in the everyday life of 32 women and men with intellectual disabilities (IDs) who require varying levels of supervision. They lived in supported living (rather independently) or group homes in community-based home-like settings. Observations during 3 days, assisted food records and anthropometric measurements were used to collect data. Dietary intake on the group level showed a varied diet and sufficient intake of all micronutrients, but a low dietary fibre intake. On the individual level, inadequate intake of micronutrients was observed, with many participants being obese, overweight or underweight. Everyday support with food, eating and meals was seen in four praxis: foodwork by oneself for oneself, foodwork in co-operation, foodwork disciplined by staff and foodwork by staff. These four practices resulted in large variations in dietary intake. The first praxis entailed more convenience food and less vitamins, the second and third, more fresh ingredients and high energy intake, and the fourth, low energy intake but rather high intake of vitamins. Sharing of meals was least common in supported living and more common in group homes and daily activity centres. The participants’ social eating spheres consisted mostly of other people with ID and staff members, and seldom other people. Whereas some preferred solitary eating, many participants considered eating together as important, but required staff support in establishing commensality. However, disturbing behaviour, as determined by the staff, could result in solitary eating. In conclusion, supporting the group rather than the individual sometimes created less favourable dietary, eating and meal outcomes. This problem needs to be addressed in order to establish food security at the individual level. In addition, actions should be taken to ensure that people with intellectual disabilities receive sufficient support to meet their individual needs and aspirations.

Application of Direct-sequencing Peptide Proteomics to the Characterization of Antagonistic (Endogenous and Exogenous) Proteins in Cereal Grains

Koziol, 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.

Food Security on Maui: Reinventing Agriculture in the Aloha State

Silver, Jade 01 April 2013 (has links)
This thesis focuses on the past, present, and future of food sustainability on Maui. It begins by explaining ancient Hawaiian agriculture and how this complex system of agriculture was deeply rooted in the customs and traditions of the Hawaiian people. The second section explores how this sustainable agricultural system changed after the arrival of Captain Cook in 1778. After western settlement, land that was once a communal resource became privatized. As land ownership shifted, the traditional subsistence agricultural system of Hawai’i began to change. Export crops such as sugar cane and pineapple became more widespread. As these crops shifted the way land was utilized in Hawai’i, the islands reduced the amount of crops grown for local consumption and became increasingly reliant on imported foods. The last section stresses the necessity of increasing the production of locally grown food on Maui. It discusses the locally grown food movement that has developed on Maui, and addresses the obstacles that prevent more food from being grown locally. Lastly, it suggests strategies to increase the amount of food produced for local consumption so that Maui can secure a more sustainable agricultural future.

McCoy, Ashley L 01 January 2011 (has links)
Food insecurity is defined as “a household‐level economic and social condition of limited or uncertain access to adequate food” (USDA Economic Research Service 2009). Low‐income households tend to be food insecure for many reasons. The first and most obvious would be the access to monetary resources. If a household does not have a sufficient income, it is difficult to keep an adequate amount of food for all household members at all times. Another reason would be that many low‐income households cannot afford a car and/or do not have easy access to public transportation or reliable private transportation.
