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.

Objective: Aboriginal children are disproportionately affected by obesity, as they are twice as likely to be classified as obese compared to their non-Aboriginal Canadian counterparts. Research indicates that income, food insecurity, and diet quality are important predictors of weight status, however these factors are not well explored among Aboriginal children living off reserve. This study aims to identify associations between food insecurity and diet on obesity status among off-reserve First Nations and Métis children. Methods: This study used both quantitative and qualitative research methods. Data from the 2006 Aboriginal Peoples Survey (APS) – Children and Youth component were analyzed using binary logistic regression and the proportional odds model to assess relationships between food insecurity, diet, and body mass index (BMI). Fruit and vegetable intake, as well as junk food consumption, were used as proxy measures for children’s diet quality. Additional analyses involving income instead of food insecurity, as well as food insecurity interaction terms, were also explored. Focus groups were conducted with caregivers of Métis and off-reserve First Nations children in Midland-Penetanguishene and London, Ontario, respectively. The focus groups were planned and carried out in partnership with the Métis Nation of Ontario (MNO) and the Southwest Ontario Aboriginal Health Access Centre (SOAHAC). A thematic analysis was conducted with the qualitative data, and the focus group discussions provided important contextual information to complement the statistical results. Results: Approximately 11% of First Nations and 6.8% of Métis children were food insecure according to the 2006 APS. The quantitative analysis did not find a significant association between food insecurity and diet, or food insecurity and BMI for First Nations or Métis children. Income was a better predictor of weight status than food insecurity. For First Nations children, having a household income higher than $60,000 decreased the risk of being overweight/obese. For Métis children, a household income of less than $20,000 increased the risk of overweight/obesity. Food insecurity was only significant as an interaction with parental education for First Nations children, and with parental education and number of people living in the household for Métis children. The proportional odds model produced similar results to the binary logistic regression procedure, and food insecurity remained insignificant in the analyses. Contrary to the quantitative findings, the focus group discussions indicated that caregivers perceived a positive relationship between low income and food insecurity, as well as adverse impacts on their children’s diets. While caregivers did not use the term “food insecurity” explicitly, conversations about not having enough food or money for food, as well as coping strategies for when these situations occurred, suggested that food insecurity manifests itself in different ways. Caregivers mentioned decreased variety of foods, compromised fruit and vegetable intake, as well as decreased traditional food consumption as examples of how families’ food consumption and purchasing patterns changed when food insecure. Food insecurity negatively impacted children’s diets, and many caregivers attributed the rise in overweight and obesity to poor diet quality. Some of the key barriers to children eating healthfully were unaffordability and limited access to healthy foods. Caregivers also discussed the role of various programs for improving child health within their communities. Conclusions: While food insecurity was not significantly associated with obesity in the quantitative analyses, discussions with caregivers of First Nations and Métis children identified food insecurity and low income as important predictors of poor diet, and consequently decreased well-being. Several limitations associated with the 2006 APS design may have prevented food insecurity from being significantly associated with obesity risk; however, it is clear from both the quantitative and qualitative components of this study that income consistently affects diet and child obesity risk. Findings from this study can inform necessary improvements to existing programs, interventions, and policies targeting obesity and health of Aboriginal children.

Increase demand for biofuel in the world as the means to mitigate global climate change, energy option and reduced fule import expenses have attracted many companies to acquire land in developing countries like Tanzania. To invest on biofuel in Africa is believed to be a means for generating incomes from expert, to employ rural people, enhance infrastructure development.However, in Africa biofuels policy is still weak. This study mainly focuses on people`s expectation during and after the investment.Issue of compensation procedure and promises seems to be a big problem; something brought tension of being cheated among local communities. Futhermore, community involvement and integration of jatropha with smallholder´s agriculture is also low.

In spite of decades-long development programs, Lesotho faces an ongoing problem of water insecurity with far- reaching individual and social impacts. The purpose of this research was to understand how women in Lesotho are impacted by the synergistic epidemics, or syndemics, of water insecurity and HIV/AIDS and how they respond to these forces. Little has been done to address how water insecurity, defined in terms of both sufficient amount and quality of water, catalyzes the syndemic impact on the people of Lesotho. Access to safe and reliable sources of water is crucial for all individuals, particularly those who have been affected by the HIV/AIDS epidemic. First, water is essential for adequate nutrition since it is required for the growing of agricultural products and for the preparation of adequate foods needed to maintain the nutritional health of those already infected with the virus. Second, food and water security is essential for the treatment of AIDS, as the complex drug regimes of anti-retroviral (ARV) medications require reliable and constant access to safe water and nutritious foods to facilitate compliance with medications. This research was also concerned with understanding the psycho-emotional experience of water insecurity. Water insecurity constrained people's ability to effectively care for their families and, as a result, created additional work and stress. Indeed, quantitative findings revealed that there was a significant relationship between water insecurity and psycho-emotional distress, and that water insecurity predicted higher scores on the Hopkins Symptoms Checklist (HSCL-25), holding constant socio-economic variables and food insecurity. Water security is dependent on many dimensions from adequate availability, secure access, and having enough water for one's daily needs. However, worry about water safety emerged as an important focus in both the qualitative and quantitative data. Water safety was a noted stress in people's daily lives, and significantly predicted increased scores on the HSCL-25. More broadly, this research theoretically informs critical medical anthropology and development anthropology. While this research was conducted in three villages in the Lesotho lowlands, this research must be contextualized within larger anthropological theory regarding international development and women in relation to it. This research combines several theories used in anthropology, international development, and social geography including political economy and structural violence, post-structuralism and governmentality, and theorizations about space and place to understand how women in Lesotho respond to globalization. Despite the proliferation of the terms participation and participatory development nearly 20 years ago, these constructs remain important in international development. While the ideology of participation originally stems from activist understandings of the role of communities in development, the use of participation has become depoliticized. As opposed to grassroots mobilization and the foregrounding of local realities, participation often means little more than a method for facilitating project implementation. Furthermore, respondents routinely discussed programs coming into communities and leaving without notice or explanation. It is imperative for donor organizations to consider the ethics of sustainability when planning and implementing new programs. In terms of community programs and grassroots organizing, findings from this research indicate that there are many material and social barriers to participation. Understanding not only women's other responsibilities but also the support they may receive from family and friends is important in any discussion of community participation. Many feminist critics of development argue that gender and class considerations have not been meaningfully addressed in policy and development programs. As global feminists argue that development aims should understand the heterogeneity of women worldwide, more research on women's perceptions of their vulnerability and their position in society is needed to inform development. Women in the global South are not passive victims and their views are important in delineating the goals and methods of development plans. Furthermore, it is important to recognize that participation may not always be in women's, or men's, best interest and that often activism and collective organizing may be more subtle than expected. In short, neither globalization nor resistance are complete power is contingent and negotiated, and thus this research reaffirms the importance of ethnography in uncovering the lived experience of globalization, or a critical ethnography of globalization.

The rapid expansion of ecotourism in the Monteverde zone of Costa Rica has increased the incidence in food insecurity in the area. Changes in food preferences and availability have led to a more homogenized diet that is increasingly delocalized and reliant on processed foods. Additionally, there has been a rapid economic shift away from agricultural and dairy farming to an economy more reliant on tourism. This NSF supported study builds upon data from a longitudinal investigation (#BNS 0753017) examining the nutritional effects of this rapid economic transition. Using a mixed methods approach, a culturally appropriate scale of stress was developed and used in conjunction with the Household Food Insecurity Access Scale, the Cohen Perceived Stress Scale, and the Hopkins Symptom Check List to explore the relationship between food insecurity and mental health among residents of the Monteverde zone. Quantitative results show that food insecurity correlated positively with stress, depression and anxiety, and was found to be a significant predictor of stress and depression

This dissertation explores issues on women’s employment and children’s health in economics. In chapter I, I investigate the causal effects of maternal employment on childhood obesity. Empirical analysis of the effects of maternal employment on childhood obesity is complicated by the endogeneity of mother’s labor supply. A mother’s decision to work likely reflects underlying factors – such as ability and motivation – that could directly influence child health outcomes. To address this concern, this study implements an instrumental variables (IV) strategy which utilizes exogenous variation in maternal employment coming from the youngest sibling’s school eligibility. With data on children ages 7-17 from the 1979 cohort of the National Longitudinal Survey of Youth linked to the Child Supplement, I explore the effects of maternal employment on children’s BMI z-score and probabilities of being overweight and obese. OLS estimates indicate a moderate association, consistent with the prior literature. However, the IV estimates show that an increase in mothers’ labor supply leads to large weight gains among children, suggesting that not addressing the endogeneity of maternal employment leads to underestimated causal effects. Chapter II examines the effects of Walmart Supercenters on household and child food insecurity. Walmart Supercenters may reduce food insecurity by lowering food prices and expanding food availability. Our food insecurity-related outcomes come from the 2001-2007 waves of the December Current Population Survey Food Security Supplement. We match these data to our hand-collected data of Walmart Supercenters at the census tract-level. First, we estimate a naïve linear probability model and find that households and children who live near Walmart Supercenters are more likely than others to be food insecure. Since the location of Walmart Supercenters might be endogenous, we then turn to instrumental variables models that utilize the predictable geographic expansion patterns of Walmart Supercenters outward from Walmart’s corporate headquarters. The IV estimates suggest that the causal effect of Walmart Supercenters is to reduce food insecurity among households and children. The effect is largest among low-income families. In the third paper, I investigate the effects of the Family and Medical Leave Act (FMLA) on women’s labor market outcomes. The FMLA is a federal policy that aims to help workers balance job and family responsibilities. However, it may have unintended consequences on employment because it imposes costs on firms. In this study, I investigate the impact of the FMLA with labor market flows—i.e., hires, separations and recalls. Focusing on labor market flow outcomes is crucial to identifying the immediate impact of the policy because employment and wages adjust slowly when there is a policy change while labor market flows are flexible. Using data from the Quarterly Workforce Indicators and adopting a triple-difference model, I get results that are unlikely to be interpreted as causal because the data are insufficient to obtain precise estimates. However, the idea of using labor market flows can be easily applied to a broad range of topics relate to workplace mandates.

This dissertation explores whether families of incarcerated fathers are more likely to experience food insecurity as a result of the conviction of the father. More specifically, I test whether food insecurity explains some of the devastating consequences of paternal incarceration on mothers and children. Because children of incarcerated fathers are at higher risk of following their fathers’ footsteps, this cycle of incarceration can be self-perpetuating. I try to determine how policy can be used to break this cycle. This dissertation examines the role of food insecurity in explaining the negative impact of paternal incarceration on the well-being of mothers and children. The United States has experienced a huge prison boom over the last 40 years. A growing proportion of the incarcerated population are parents. Children growing up with one or both parents missing tend to have long-lasting disadvantages. Previous studies have attempted to suggest a few mechanisms through which paternal incarceration has negative consequences for families but has not considered the role of food insecurity. I propose a theoretical framework to show that paternal incarceration negatively affects mothers and children through food insecurity. Using a longitudinal study of fragile families, I find that food insecurity explains some of the negative consequences of paternal incarceration on maternal depression. On the other hand, food insecurity plays no role in the effect of paternal incarceration on child behavior problems. The findings also cast doubt on whether paternal incarceration affects child well-being. The implications for policy are two-fold. First, reducing food insecurity would mitigate the negative effects of paternal incarceration on maternal depression. More research is needed in order to understand whether the negative effects of paternal incarceration on maternal well-being can be further mitigated. Second, prison reform would do little to reduce the behavior problems experienced by children of incarcerated fathers. Rather than incarceration, other factors contributing to social disadvantages could explain why children of incarcerated fathers have more behavior problems than other children.

Hunger and food insecurity exist across millions of households in the US, and in even greater numbers in the state of Georgia. In fact, Georgia ranks fourth among the ten states with the highest food insecurity. Hunger and food insecurity have negative implications for the health and well being of children and adults. Such outcomes include fatigue, headaches, and frequent colds among children, and worsening chronic and acute diseases among adults. A non-governmental approach to addressing hunger and food insecurity includes food-banking. The Atlanta Community Food Bank (ACFB) collects, warehouses, and distributes 2 million pounds of food and other donated items to Georgia households each month. Among its other activities, the ACFB collects food donations through food drives. The capstone project, Colleges Connect to Collect, was created to assist Atlanta college students in hosting food drives on their college campuses. There were 2088 pounds of food collected and donated to the ACFB through the project. Recommendations for sustaining the project are included in this report.
