Item Understanding Women’s Labor Force Participation in Sub-Saharan Africa Through Migration, Kin Support and Relationship Dynamics(2024) Kim, Seung Wan; Madhavan, Sangeetha; Sociology; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Family sociologists and demographers have long maintained a profound interest in understanding the determinants and consequences of female labor force participation. Much of this research has predominantly concentrated on the Western contexts, albeit with a handful of remarkable works shedding light on the Global South, where is also witnessing a growing focus. However, our comprehension of the intricate interplay between gender, work, and family in sub-Saharan Africa remains insufficient and restricted. Over the years, there has been a steady increase in women's education and labor force participation in this region. Yet, many women continue to grapple with sociocultural barriers that hinder them from fully harnessing their employment opportunities.Particularly noteworthy is the mounting tension between conforming to traditional gender roles and meeting household needs through women's paid employment, especially in the face of increasingly challenging economic circumstances. This challenge is particularly pronounced among marginalized populations, such as rural and low-income urban population. My doctoral dissertation seeks to address three hitherto understudied issues: 1) examining the relationship between an individual's employment status and that of other household members in South Africa, and how it influences that individual's likelihood of future migration, 2) investigating the role of employment among kin members and the support provided by family members in facilitating women's employment in Nairobi, Kenya, and 3) exploring the dynamics of women's work concerning union formalization, motherhood, and livelihood in Nairobi. The dissertation comprises two quantitative analyses and one qualitative methods study, resulting in three papers that draw from two datasets collected in South Africa and Kenya.Item Characterizing Small-Town Development Using Very High Resolution Imagery within Remote Rural Settings of Mozambique(MDPI, 2021-08-26) Chen, Dong; Loboda, Tatiana V.; Silva, Julie A.; Tonellato, Maria R.While remotely sensed images of various resolutions have been widely used in identifying changes in urban and peri-urban environments, only very high resolution (VHR) imagery is capable of providing the information needed for understanding the changes taking place in remote rural environments, due to the small footprints and low density of man-made structures in these settings. However, limited by data availability, mapping man-made structures and conducting subsequent change detections in remote areas are typically challenging and thus require a certain level of flexibility in algorithm design that takes into account the specific environmental and image conditions. In this study, we mapped all buildings and corrals for two remote villages in Mozambique based on two single-date VHR images that were taken in 2004 and 2012, respectively. Our algorithm takes advantage of the presence of shadows and, through a fusion of both spectra- and object-based analysis techniques, is able to differentiate buildings with metal and thatch roofs with high accuracy (overall accuracy of 86% and 94% for 2004 and 2012, respectively). The comparison of the mapping results between 2004 and 2012 reveals multiple lines of evidence suggesting that both villages, while differing in many aspects, have experienced substantial increases in the economic status. As a case study, our project demonstrates the capability of a coupling of VHR imagery with locally adjusted classification algorithms to infer the economic development of small, remote rural settlements.Item Fire Regions as Environmental Niches: A New Paradigm to Define Potential Fire Regimes in Africa and Australia(Wiley, 2022-07-07) Zubkova, M.; Boschetti, L.; Abatzoglou, J. T.; Giglio, L.Despite the widespread use of the “fire regime” concept for describing spatial and temporal patterns and ecosystem impacts of fire, this concept lacks an unambiguous, quantitative definition. By adopting from the ecological literature the concept of climate niche, that is, the environmental conditions that allow a specie to exist, we propose a new framework where variables that promote fuel accumulation and desiccation were used to define the environmental space at the continental level, later divided into regions (“fire regions”) with distinct fire potential. Our proposed approach emphasizes climate controls on fire patterns, distinct from the controls that humans exert on observed fire activity. By applying this framework, we identified nine fire regions in Africa and eight in Australia, distinguishing differences in fire patterns between continents as a result of changes in environmental gradient. Not only did we find that fire size and intensity varied significantly between continents, but biomes at a continental level were also found to be heterogeneous in terms of fire frequency, size, and intensity. For example, within African tropical savannas, the total annual rainfall and tree cover change drastically North and South of the equator, resulting in fire regions with significantly different fire characteristics. Meanwhile, in Australia, a strong gradient of annual temperature and precipitation seasonality was observed within tropical savannas and xeric shrublands, which was recognized by dividing those biomes into five regions with statistically different fire activity. Additionally, human presence led to some heterogeneity of fire patterns within delineated fire regions that also varied across biomes.Item Considerations for AI-EO for agriculture in Sub-Saharan Africa(Institute of Physics, 2023-03-24) Nakalembe, Catherine; Kerner, HannahAdapting to and mitigating climate change while addressing food insecurity are top priorities in SubSaharan Africa that require technologies to improve rural livelihoods with minimal environmental costs [1]. Artificial intelligence (AI) offers great promise for climate-smart solutions that improve food security outcomes. While precision agriculture is often the foremost use case for AI in agriculture (e.g. automation of farm equipment or nutrient application), precision agriculture is out of reach for most African farmers due to the required capital and infrastructure. AI solutions using satellite Earth observations (EOs), which we call AI-EO, are more accessible in the near term. EO enables agricultural analyses and insights at global scales, and many datasets are freely available, making EO-based solutions affordable [2]. AI-EO-derived products such as crop type maps and yield estimates are necessary to forecast food production surpluses or deficits, inform trade, and aid decisions. These products can support policies that accelerate the design and adoption of climate-smart agriculture and impact farmer livelihoods by increasing access to actionable early warning, risk financing or insurance [3], farm inputs, markets, and costreducing interventions [2, 4]. Despite their promise, AI-EO solutions for agriculture in Africa are still limited. Most techniques are not generalizable across heterogeneous landscapes. In this paper, we describe the principal sub-fields of research in AI-EO for agriculture in Africa and discuss examples and limitations of existing work. We also propose ten considerations for future work to help increase the impact of AI-EO research in Africa.Item Autochthonous and Introduced Stores of Biomass Value: Measuring Resilience Outcomes of Enset and Eucalyptus as Green Assets in Three Representative Smallholder Farm Systems of Ethiopia(2020) Morrow, Nathan; Hansen, Matthew C; Geography; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Fundamental shifts in the ability to observe our world with synoptic satellite remote sensing and the profusion of trend tracking longitudinal data sources not only better inform us of the mounting trouble our planet is in but also provide completely new perspectives on basic shared understandings, such as how many trees grow on Earth and where they take root. Observing the dispersed pattern of increasing tree cover across a multidecadal satellite mosaic, developed by Matt Hansen and colleagues at University of Maryland at College Park, sparked an interest in the ramifications of this unanticipated change, marked clearly upon the landscape in Ethiopia. The following chapters explore the relation of changing amounts of autochthonous treelike perrenial enset and introduced eucylyptus trees, commonly found on Ethiopian farms, to smallholder resilience, food security, and well-being. Spatially informed longitudinal models for three representative subnational data sets are used to investigate the central thesis of this dissertation—trees and treelike perennials on farms in rural Ethiopia indicate a fundamental store of value in living biomass, building a household’s assets over time through improved biomass management, for resilient small farm livelihoods that ensure food security and related well-being. Green assets acting as biomass stores indicate natural “value,” representing transformed and stored energy of the sun, that Blaikie and Brookfield (1987) considered inadequately captured as a no-cost contribution to the “use value” concept in development economics, economic geography production, and income-focused research, as well as in Marx’s (1887/2013) labor-focused value constructs that only briefly acknowledge workers are helped by the transformative “natural forces” at work on the land. Model results presented in Chapters 3, 4, and 5 reveal a lack of on-farm trees and treelike perennials often indicates biomass poverty and energy insecurity. Chronic biomass poverty, measured with spatially aware hierarchal models, is related to an inability to maintain a sufficient level of essential green assets, thereby contributing to poor resilience and well-being outcomes on small farms. On the other hand, medium and longer term asset accumulation supports improved well-being when livelihood strategies make use of farm forests, other on-farm trees, and treelike perennials.Item ELECTORAL LOSS AND CONTENTION(2019) Patch, Allison Kathryn; Birnir, Johanna K; Government and Politics; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)This dissertation is an exploration of the consequences of elections for those kept out of power. I draw from both the winner-loser gap literature, which explores attitude differences between winners and losers following elections focusing on individual voters as they process electoral results, and the electoral contention literature, which examines the causes and consequences of protests, riots, and violence connected to electoral contests focusing on the elites. My dissertation works to bring these two literatures by examining the factors that create opportunities for attitude and behavioral change for those who are unable to access power in the aftermath of elections. The first two papers use surveys to focus on individuals—their personal identities and their attitudes towards democracy and political contention or violence. The third paper examines the motivations of individual leaders in making public accusations of fraud and the consequences these accusations have on the voters’ perception of the legitimacy of elections and the likelihood of electoral contention. Through the ideas explored in these papers, this dissertation provides further context for differences in attitudes between winners and losers towards democracy and contention, while also cautioning some of the more dire predictions of the consequences of the gap in perceptions and attitudes between winners and losers. Additionally, by examining the ramifications of fraud accusations in the wake of election loss, we can see a better picture of the kinds of motivations that can successfully mobilize those out of power to contention.Item Corruption, Reform, and Revolution in Africa's Third Wave of Protest(2019) Lewis, Jacob Scott; McCauley, John F; Government and Politics; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)What explains diverging calls for reform and revolution in Africa over the past ten years? African countries have made substantial strides toward actual democratic devel-opment, including a concerted effort to address corruption. As African democracies have strengthened, calls by citizens for anti-corruption reform have grown, highlighting the progress that is being made. Yet, in recent years, some anti-corruption movements have called instead for revolution - completely replacing the state or seceding altogether. What explains these calls for revolution? I argue that we need to understand how differ-ent types of corruption shape contentious goals. When corruption generates material benefits, citizens lose trust in politicians but do not lose trust in the system. In response, they call for reform, seeking to improve the system. When corruption generates system-ic benefits (distorting the system altogether), citizens lose trust in the institutions and instead call for revolution. I test this using individual-level data from survey experi-ments as well as large-n surveys, and group-level data using statistical analysis of pro-test events as well as case studies. I find strong support that types of corruption matter greatly in shaping contentious politics in Africa.Item Violence and Belonging: The impact of citizenship law on violence in Sub-Saharan Africa(2016) Fruge, Anne Christine; Birnir, Johanna K; Government and Politics; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Many countries in Africa are embroiled in heated debates over who belongs where. Sometimes insider/outsider debates lead to localized skirmishes, but other times they turn into minor conflict or even war. How do we explain this variation in violence intensity? Deviating from traditional explanations regarding democratization, political or economic inequality, or natural resources, I examine how nationality laws shape patterns in violence. Citizenship rules determine who is or is not a member of the national political community. Nationality laws formalize these rules, thus representing the legal bond between individuals and the state. Restrictive nationality laws increase marginalization, which fuels competition between citizenship regime winners and losers. This competition stokes contentious insider/outsider narratives that guide ethnic mobilization along the dual logics of threat and opportunity. Threats reduce resource levels and obstruct the exercise of rights. Opportunities provide the chance to reclaim lost resources or clarify nationality status. Other work explains conditions necessary for insider/outsider violence to break out or escalate from the local to the national level. I show that this violence intensifies as laws become more exclusive and escalates to war once an outsider group with contested foreign origins faces denationalization. Groups have contested foreign origins where the “outsider” label conflates internal and foreign migrants. Where outsiders are primarily in-migrants, it is harder to deny the group’s right to citizenship, so nationality laws do not come under threat and insider/outsider violence remains constrained to minor conflict. Using an original dataset of Africa’s nationality laws since 1989, I find that event frequency and fatality rates increase as laws become more restrictive. Through case studies, I explain when citizenship struggles should remain localized, or escalate to minor or major conflict. Next, I apply a nationality law lens to individual level conflict processes. With Afrobarometer survey data, I show that difficulty obtaining identity papers is positively correlated with the fear and use political violence. I also find that susceptibility to contentious narratives is positively associated with using violence to achieve political goals. Finally, I describe the lingering effects of a violent politics of belonging using original survey data from Côte d’Ivoire and Ghana.Item Police Legitimacy in Sub-Saharan Africa(2016) Behlendorf, Brandon Paul; LaFree, Gary; Criminology and Criminal Justice; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Is fairness in process and outcome a generalizable driver of police legitimacy? In many industrialized nations, studies have demonstrated that police legitimacy is largely a function of whether citizens perceive treatment as normatively fair and respectful. Questions remain whether this model holds in less-industrialized contexts, where corruption and security challenges favor instrumental preferences for effective crime control and prevention. Support for and against the normative model of legitimacy has been found in less-industrialized countries, yet few have simultaneously compared these models across multiple industrializing countries. Using a multilevel framework and data from respondents in 27 countries in sub-Saharan Africa (n~43,000), I find evidence for the presence of both instrumental and normative influences in shaping the perceptions of police legitimacy. More importantly, the internal consistency of legitimacy (defined as obligation to obey, moral alignment, and perceived legality of the police) varies considerably from country to country, suggesting that relationships between legality, morality, and obligation operate differently across contexts. Results are robust to a number of different modeling assumptions and alternative explanations. Overall, the results indicate that both fairness and effectiveness matter, not in all places, and in some cases contrary to theoretical expectations.Item Exploring the Impact of Neighborhood on State-Building in sub-Saharan Africa(2013) Garcia, David; Reed, William L; Government and Politics; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Why is state-building more advanced in some sub-Saharan African countries than in others? And, over time, what accounts for the steady gains, steady declines, or gains followed by declines (or vice-versa) observed in the state-building trajectories of Africa's states? This dissertation endeavors to shed light on these questions by assessing the impact of one suspected cause of state-building variation: the way power is distributed among states and their neighbors. Specifically, this dissertation assesses whether the relative distribution of power provides incentives or disincentives to regimes in charge of states to pursue policies that are conducive or detrimental to state-building. Employing OLS, two hypotheses are tested: one which predicts that regimes in charge of relatively weak states promote policies conducive to state-building, and another which predicts that regimes in charge of relatively weak states opt for a strategy of personal rule that runs counter to the imperatives of state-building. Findings are mixed and often contingent upon how state-building is measured; when state-building is assessed in terms of how proficiently the state regulates social and economic life, provides infrastructure services to its population, and promotes human development, support is found for the latter hypothesis. Yet when state-building is measured in terms of how well the state monopolizes the legitimate use of force or forges convergence between nations and the state, no statistically significant relationship in either direction is found. Thus, while there is at least some evidence that the regional distribution of power impacts the state-building process, it does not appear to do so quite as robustly as expected.
