Food insecurity is a condition of insufficient access to quality nutritious food; it is often rooted in shocks that interrupt the food production/distribution system in an area. Amidst the capabilities of Nigeria's agricultural system, the number of households across Nigeria experiencing food shortages has increased rapidly. The main reason for this increase were price shocks. This incident highlighted a huge vulnerability in Nigeria's food system, the vulnerability to price shocks. Incidences such as poverty and conflicts magnify the frequency of food insecurity. The ability to reduce vulnerabilities while addressing existing issues in food production and supply depends on a stable economy and innovative policy. As a major oil exporter, Nigeria's economy is affected by oil price fluctuations. This paper analyses the extent of the effect and how such volatility could increase vulnerability in the food system. The analysis in this treatise examines economic and agricultural factors to identify trends that negatively affect Nigeria's current food system.. Oil prices were significant in explaining variation in food price shocks and Gross Domestic Product (GDP). Food price shocks are one of the symptoms of economic downturns. Agricultural innovation, and economic policies need to be formulated to prevent such shocks in the future. Given the dependency of economic performance on oil prices, a major move would be to diversify the Nigerian economy; with adequate attention being paid to agriculture.

The present thesis aims to recount the current situation of the Alevi community in the urban Turkish setting. The data were collected during eight months of ethnographic field research from February 2009 to October 2009 in a complex preferred to be called as the Dikmen Alevi Community Center, in Ankara. I present different ways adopted by various groups while explaining what Alevism is and I stress the fact that there is a certain degree of fragmentalization within the community due to such diverse descriptions. Thenceforth, I emphasize the reasons behind the existence of divergent classifications and analyze Alevis&rsquo / migration from rural to urban areas during 1970s and 1980s as it relates to the changes in the institutions. After offering an evaluation of the changes accompanying migration, I accentuate the competitive sharing of the city as a religious space between Alevis and Sunnis concentrating on Alevis&rsquo / perception of religious space and providing a comparison between Sunni and Alevi perceptions regarding the places of worship. Subsequently, I attempt to show that there is a competitive sharing relationship present within the community giving the example of Dikmen Alevi Community Center after the establishment of the Alevi Institute for Research, Documentation and Application. I conclude that this kind of a relationship and the current state of affairs are the results of the struggle to adapt to a changing environment, which in turn alters the individuals themselves.

Widely considered the world’s largest migration, the ongoing rural-to-urban migration in China is unprecedented in terms of scale and impact. Millions of Chinese peasants flood to cities in waves to try their fortune. Among them, dagongmei, literally translated as “working sisters,” who are single, young, and undereducated rural women working in cities, are believed to be one of the most marginalized communities. Their segregation and discrimination in the labor market has been well documented. As a major life event, their marriages have also received academic attention, but the marriage of dagongmei in current literature is generally considered a means towards achieving social advancement, often terminating their migratory trajectory. Few studies address the question of how physical mobility and economic independence alter the social relations of dagongmei in their pursuit of dating and potential spouses across the rural-urban divide. The separations of dagongmei from patriarchal families empower them, but their legally classified rural citizenship and their lack of cultural and social capital constrain their aspirations. To closely examine how individual agency interacts with familial control and societal constraints, I conduct in-depth interviews with dagongmei, applying feminist standpoint theory, to hear their experiences concerning the social processes of mate selection. By situating marriage as a dynamic decision-making process, I identify three subgroups of women: independent seekers, resigned negotiators, and tradition reformers. My overall conclusion is that young rural women are empowered by their migration to pursue major life goals such as marriage, but traditional gender ideology still operates to confine their roles as daughters and wives in a transitional society with competing capitalist and socialist characteristics. / text

This thesis focuses on gender and scale as key aspects of the rural-to-urban migration process in China. Its specific aim is to connect economic and social reasons for rural women's migration towards urban factory work. Contemporary large-scale migration studies show inconsistencies and contradictions concerning reasons for migration, especially as it relates to gender. Thus, migration research often emphasizes the positive social changes experienced by women workers, in effect signaling that the most important needs of women migrants can be satisfied without economic gains. In contrast, the proposed study seeks to show that social and economic reasons intertwine within women's experiences of and explanations for their migration. The theoretical framework for the proposed study is based on postmodern understandings of gender, economy, and society. Data for the study was acquired through qualitative techniques, specifically through interviews with workers. The findings of this study supported the thesis that both economic and social factors informed women's decision to become migrants. In addition, this study revealed specific experiences of women workers related to migration. Thus, women decided to become migrants largely because their education allowed them to gain employment in urban areas and ability to gain independent income. Although social networks played a large role in the recruitment of rural women workers, they were not necessary to find employment. Experiences of v vi factory work reveal that the relationship between women and their employers are less restrictive than expected. In addition, rural women's experiences of being migrants in the city, although constrained by timings of factory work, encompass both material and social forms of consumption. Overall, migration outcomes reflected changing social status of women in the rural areas. Thus, this research approaches migration as a dynamic process. Embedded in this process are fluid identities of migrant women workers. Through questioning the meanings of 'social' and 'economic' migration, this research adds to existing studies on gender and migration in China and contextualizes the value of women workers to China's economy. Alongside, the study moves away from shop floor politics to the wider space outside the factory, thus linking urban and rural contexts. In a broader sense, this research aims to inform theories related to the economics and politics of migration through adding a spatial component to social understandings of the gendered migration process.

Background: Internal migration, a consequence of the demographic transition towards urbanization driven by globalization, represents a particular public health challenge. Change in residence from one sociocultural geographic context to another, with not only economic implications, but also changes in women’s long-established relationships of family interdependence, influences gender relations and can influence Intimate Partner Violence (IPV) against women. Different migratory trajectories may be related to IPV. The aim of this study was to identify the association between internal migration and physical and/or sexual violence against women in the last 12 months. Methods: A secondary analytical cross-sectional analysis of the publicly accessible 2015–2017 Demographic and Family Health Survey (DHS) was performed. The outcome variable was reported physical and/or sexual violence inflicted by the partner (IPV) during the last 12 months. Exposure variable was internal migration, operationalized from three questions: current place of residence, principal place of residence before 12 years of age and number of years of residence in the current place. Migrants were classified as those who reported having lived for 5 years or more in the current location and were categorized as rural-rural migrants, urban-urban migrants, urban–rural migrants and rural–urban migrants, recent migrants and nonmigrants those who resided in the same place all their lives. To identify the association between internal migration and physical violence, a generalized linear model (GLM) of the family and the log Poisson link log option was used, and the results are presented as prevalence ratios (PRs). A crude model and a model adjusted for confounding variables were performed. Results: Rural–urban migrant women had a 15.0% higher probability of experiencing IPV than nonmigrant women (PRa 1.15, 95% CI 1.03–1.29, p = 0.015), while the probability of experiencing IPV in the last 12 months for urban–rural, rural-rural,urban-urban migrantand recent migrant women was not significantly different from that of nonmigrant women. Conclusion: Rural–urban migration among women of childbearing age is a factor associated with a higher probability of IPV in the last 12 months. The identification of women with this rural–urban migration pattern could help prioritize those that may experience a greater probability of physical and/or sexual violence in Peru, it must be studied if this pattern is the same in other countries. / Revisión por pares

This dissertation consists of three essays studying the determination and evolution of labor supply in China. The analysis especially focuses on the labor market behavior of the wage workers with urban registration (Hukou). The first chapter outlines the dissertation by briefly discussing the motivations, methods, and main findings in each of the following chapters. Chapter two examines the evolution of female labor supply in urban China. Female labor force participation rate in China has been declining rapidly over the last three decades. Using a time series of cross-sections from the Chinese Household Income Project Series (CHIPS), this chapter attempts to systematically relate the decrease in female labor force participation to the socio-economic changes happening in China during the same period, and assess their respective contributions. Adopting both linear and non-linear decomposition techniques, the results show that during 1988-1995, changes in population age distribution and family size both contribute, during 1995-2002, age effect dominates, and during 2002-2007, non-labor income effect dominates in explaining the decreasing trend in female labor force participation. Chapter three investigates the impact of social norms on married women's labor supply decision in China. Using data from the China General Social Survey (CGSS) and the China Family Panel Studies (CFPS), we find a strong and robust positive correlation between the labor supply behavior of a married woman and the former work experience of her mother-in-law. Our estimation results indicate that being raised by a working mother influences both a man's attitude toward gender roles and his household productivity, and therefore married women whose mothers-in-law were not working are themselves significantly less likely to participate in the labor force. The last chapter evaluates the labor market consequence of rural-to-urban migration in China. Starting from the mid-1990s, there is a remarkable increase in the number of migrant workers in cities, from around 39 million in 1997 to 145 million by 2009 (Meng et al. 2013). Chapter four intends to explore how does this important economic event affect the labor market conditions of urban residents. Specifically, we estimate the possible employment and earnings displacement effects of rural-to-urban migration on urban residents by exploiting regional variation in the rural migrant share of education-experience cells. We use multiple sets of instrumental variable to address the potential endogeneity problems associated with the rural migrant ratio in a city. The estimation results are consistent with the predictions of the textbook model of a competitive labor market, indicating the inflow of rural migrants reduces the wage and labor supply of competing urban residents. / Ph.

Urbanisation and the associated nutrition transition have been linked with the recent rise in osteoporotic fragility fracture incidence in many countries. Predictions indicate that hip fracture incidence will increase 6-fold in Africa and Asia by 2050, partially attributed to demographic transition and population ageing. Differences in areal bone mineral density (aBMD) between rural and urban locations indicate that urban regions of high-income countries (HIC) have lower aBMD and a higher incidence of hip fracture. The few studies conducted in low and middle-income countries (LMIC) provide inconsistent results; in contrast to HIC, most have found higher aBMD in urban populations. To investigate the impact of migrating to an urban environment, detailed studies of bone phenotype and factors affecting bone health have been conducted in two groups of pre-menopausal Gambian women: urban migrant (n=58) and rural (n=81). Both groups spent their formative years in the same rural setting of Kiang West, urban women were known to have migrated to coastal districts, concentrated in Brikama and Kanifing, when aged ≥16 years. Bone phenotype (bone mineral content (BMC); bone area (BA); aBMD, and size-adjusted BMC (adjusted for height, weight and BA) of the whole-body, lumbar spine and hip) was measured by dual energy x-ray absorptiometry (DXA), with further characterisation by peripheral quantitative computed tomography (pQCT). Data were also collected on anthropometry, body composition, food and nutrient intakes, physical activity, socio-demographic characteristics, vitamin D status, and 24hr urinary mineral outputs (Na, K, P, and Ca). Mean age and height of rural and urban migrant groups were not significantly different (p > 0.05). Urban migrant women were significantly heavier (p < 0.01). Significant differences in BMC and aBMD were found between groups at all skeletal sites, with urban women having higher BMC and aBMD; BA was not significantly different. The greatest difference in BMC was found at the lumbar spine (8.5% ± SE 3.0, p < 0.01), a meaningful difference, equivalent to 0.76 of rural SD. T- Scores were also calculated using a young adult (white, female) reference population, mean T- scores were -1.03 and -0.22, for rural and urban groups respectively. After adjusting for size, differences in whole-body and hip BMC were mostly attenuated (p > 0.05), but difference in spine BMC remained significant (6.2% ± SE 2.1, p < 0.01). These results indicate that rural-to-urban migration is associated with higher BMC; BA and height were similar, and difference in body weight could not fully account for higher BMC at the lumbar spine. Calcium intakes were low in both groups, urban migrant 294mg/d (IQR: 235 to 385) and rural 305mg/d (IQR: 222 to 420). Urban women had significantly lower intakes of potassium, magnesium and dietary fibre (p < 0.01), related to lower consumption of fruit, green leafy vegetables and groundnuts. 25-hydroxy vitamin D status was good in both groups, urban migrant 64.0 ± 14.2nmol/L and rural 68.3 ± 15.7nmol/L (M ± SD, p > 0.05). Implications for bone health of the nutrition and demographic transition, principally future fracture risk and other non-communicable diseases require further research in LMICs. ORIGINAL CONTRIBUTION TO KNOWLEDGE To my knowledge, this is the first study investigating the impact of rural-to-urban migration on bone health to be conducted in sub Saharan Africa. It is the first study of bone health and determinants of bone health in an urban population in The Gambia.

<p dir="ltr">This dissertation analyzes the sixty-four (64) page handwritten ledger of Mrs. Goldleana Harris (also known as Mrs. Mosley Abraham Gibbs, 1920–1986), kept between 1944 and 1960. Harris is a Black woman born in Longstreet, Louisiana DeSoto Parish. She lived in Shreveport, Louisiana from 1949–1986. Using a case study approach and close reading analysis of Mrs. Goldleana’s writings, I document a Black woman’s lived experience and the historical significance of Hollywood, a segregated Black neighborhood in Shreveport, Louisiana and related gathering spaces within the Deep South region of the United States between 1944 and 1960. These spaces include five areas of significant and overlapping importance: The Family House, The School House, The Church House, The Labor (Work) House, & The Play (Leisure) House. </p>
