Urban land dynamics in the Abuja city-region, Nigeria

Enoguanbhor, Evidence Chinedu 20 December 2021 (has links)
Die schnell wachsende Dynamik urbaner Räume stellt global eine große Herausforderung für die urbane und ökologische Nachhaltigkeit dar. In den Stadtregionen in Subsahara-Afrika stehen die Strategien und Instrumente der Landnutzungsplanung, die zur Steuerung der urbanen Dynamik für die urbane und ökologische Nachhaltigkeit eingesetzt werden, vor verschiedenen Herausforderungen, einschließlich der unzureichenden Verfügbarkeit von Daten. Das Ziel dieser Forschung ist es, zu einer effektiven Landnutzungsplanung zur Verbesserung der urbanen und ökologischen Nachhaltigkeit beizutragen, indem integrierte empirische Daten aus Geographischen Informationssystemen, Fernerkundung und Umfragen genutzt werden, um detaillierte und neue Einblicke in die urbane Landdynamik zu bieten. Bei der Untersuchung der Diskrepanzen zwischen der vergangenen und der aktuellen städtischen Landbedeckung und den Flächennutzungsplänen wurde die überwachte Klassifizierung (supervised classification) der Landbedeckung von LANDSAT-Daten aus den Jahren 1987, 2002 und 2017 verwendet, um die nicht-städtischen Entwicklungsflächen zu quantifizieren, die an die Stadt/Bebauung verloren gingen. Experteninterviews wurden zur Anleitung und Entwicklung von drei Szenarioalternativen zur Simulation der Landbedeckung von 2017 bis 2030 und 2050 unter Verwendung des Multi-Layer Perceptron Neural Network und Markov-Modellen verwendet. Die Ergebnisse zeigten eine Zunahme der städtischen/bebauten Flächen und große Unstimmigkeiten zwischen der früheren/aktuellen städtischen Landbedeckung und den bestehenden Flächennutzungsplänen. Außerdem zeigten die Ergebnisse eine hohe, geringe und keine potenzielle Beeinträchtigung der geschützten ökologisch sensiblen Gebiete durch die zukünftige urbane Dynamik unter den Szenarien "Business As Usual", "Adjusted Urban Land" und "Regionaler Flächennutzungsplan". Die Methoden und die zur Verfügung gestellten Basisinformationen, insbesondere aus dem “Adjusted Urban Land” Szenario, wären für eine effektive Flächennutzungsplanung von Nutzen. Dies würde dazu beitragen, die urbane und ökologische Nachhaltigkeit der Stadtregionen in Subsahara-Afrika und im gesamten Globalen Süden zu verbessern, wo eine unzureichende Datenverfügbarkeit die Flächennutzungsplanung erschwert. / Global urban dynamics are rapidly increasing, posing a great challenge to urban and environmental sustainability. In Sub-Saharan Africa city-regions, land use planning strategies and instruments used to guide urban dynamic patterns for urban and environmental sustainability are faced with various challenges, including insufficient data availability. The goal of this research is to contribute to effective land use planning for improving urban and environmental sustainability using integrated empirical data derived from Geographic Information Systems, Remote Sensing, and surveys to offer detailed and new insights into urban land dynamics. While investigating the mismatches between the past and current urban land cover and land use plans, the supervised classification of the land cover of LANDSAT data from 1987, 2002, and 2017 was used to quantify the non-urban development areas lost to urban/built-up. Expert interviews were applied to guide and develop three scenario alternatives to simulate land cover from 2017 to 2030 and 2050 using the Multi-Layer Perceptron Neural Network and Markov models. The results indicated an increase in urban/built-up areas and large mismatches between the past/current urban land cover and the existing land use plans. Also, the results indicated high, little, and no potential degradation of the protected environmentally sensitive areas by the future urban dynamics under the Business As Usual, Adjusted Urban Land, and Regional Land Use Plan scenarios respectively. The methods and the baseline information provided, especially from the Adjusted Urban Land scenario would be useful for effective land use planning. This would support improving the urban and environmental sustainability of the Sub-Saharan African city-regions and across the Global South, where insufficient data availability challenges land use planning.

Attracting, Recruiting, and Retaining Qualified Faculty at Community Colleges in Sierra Leone

Betts, Gloria 01 January 2017 (has links)
This case study was designed to explore policies that were in place to attract, recruit, and retain qualified faculty for 4 community colleges in Sierra Leone. The research was necessitated by the apparent inability of Sierra Leone educators to train and retain faculty possessing the required academic credentials. The research questions were designed to address the policies and strategies used to attract and recruit faculty, better prepare faculty, improve the quality of classroom instruction, and retain qualified faculty at community colleges. The literature review yielded results about the benefits of community colleges in developing countries, thus reinforcing the need for qualified faculty. Case study methodology and open-ended interviews with 12 purposely selected participants were used to ensure trustworthiness and reveal the essential characteristics of how community colleges in Sierra Leone may succeed in faculty attraction, recruitment, and retention. Participants reported that word of mouth solicitation was the primary method for faculty recruitment, and that the top challenge faced by these institutions was fiscal constraints. Although findings from this study are specific to 4 institutions, they may serve as a guide for qualified faculty retention at all community colleges in Sierra Leone, and hopefully bring about social change by improving academic excellence throughout the country.

HIV/AIDS-Related Stigma and Discrimination Toward Women Living with HIV/AIDS in Enugu, Nigeria

Nnajiofor, Chinyere Fidelia 01 January 2016 (has links)
HIV/AIDS-related stigma and discrimination (S&D), lack of social support, poverty, and gender inequalities have been identified as factors in the increased prevalence rate of HIV transmission in Enugu, Nigeria, especially among women ages 15 to 49 years. Despite the funding of reduction programs, HIV/AIDS-related S&D remain a major driving force in the increased rate of new HIV cases in Enugu. This study addressed a perceived need for behavioral change intervention approaches that span all societal factors to reduce the HIV infection rate in Enugu Nigeria. The study was guided by Goffman's (1963) social S&D theory. The sample was composed of 132 women living with HIV/AIDS WLWHA ages 21 to 54 years, purposefully sampled from the 4 HIV and AIDS comprehensive initiatives care centers in Enugu, Nigeria. Fifteen WLWHA were interviewed and 114 participated in an online survey. The descriptive statistics and a multiple linear regression analysis and comparison revealed a convergent significant relationship between the S&D determinants (social, political, psychological, environmental, and cultural) and HIV/AIDS-related S&D towards WLWHA in Enugu F (4,109) = 45.09, p

Trade agreements with occupying powers : A case study of the EU external action in Western Sahara from a social justice perspective

Wahlqvist, Theresa January 2021 (has links)
For the past 20 years, the European Union has extended its political cooperation and bilateral trade agreements with Morocco, while not taking a clear stance against the occupation of Western Sahara. Bound by EU law as well as principles of human rights and international law, the institutions of the EU are obligated to respect human rights in the EU external action. This includes the right to self-determination, a customary principle of international law. In two rulings, the Court of Justice of the European Union has concluded that agreements between the EU and Morocco do not apply to Western Sahara. But since then, two new agreements have been concluded whose respective scope include the territory and the waters of Western Sahara. Yet, the people of Western Sahara are not party to any of the agreements which authorises the exploitation of its natural resources. Drawing upon this context, this thesis examines the human rights aspect of the EU’s international agreements using a set of different research methods. The research question, if and how the EU’s external action affecting Western Sahara complies with EU law, is answered through a doctrinal analysis of the human rights clause of three separate agreements between the EU and Morocco, and the relevant case law of the Court. The conclusions are discussed in a following extrajudicial assessment based on Nancy Fraser’s critical theory of social justice.  The thesis finds that the EU external action as manifested in the three agreements with Morocco, by including the territory of Western Sahara, does not comply with EU law. Further, the analysis discovers that the lack of coherence between the institutions creates a fragmented external policy, whose legal basis and objectives in regard to respect for human rights is not reflected in its implementation. The discussion discovers that the EU fails to recognise the people in Western Sahara as equal subjects of social justice by upholding an unjust political frame. This framing maintains the status quo and obstructs the people’s claims for redistribution, recognition and political representation. The thesis therefore concludes that the EU should change its policy regarding Western Sahara, and align with the guiding principles for the external action stated in the treaties (Article 21 TEU). The thesis suggests that the EU adopts a comprehensive critical democratic and inclusive approach, in order to improve its institutional framework for how international agreements are negotiated, implemented and monitored in occupied territories.

Exploring the Economic Relationship Between China and Sub-Saharan Africa : A Study on the Role of Chinese Foreign Direct Investments in Sub-Saharan Africa

Pettersson, Axel, Patel, Rushil January 2023 (has links)
This paper adopts a quantitative and qualitative lens, through which we explore the economic relationship between the region of Sub-Saharan Africa and China as a consequence of Chinese Foreign direct investments (FDI).  Primarily, the paper’s direction, analysis, and discussions are dictated by the usage of primary and secondary data. Our primary data is constructed as a panel data set including GDP for 38 countries alongside the Chinese FDIs for each country during the period 2003-2021. Our secondary data includes already existing papers on topics related to our purpose and the data found in them. The main points include the economic development of Sub-Saharan Africa, the subsequent enforced Chinese economic policy, and further the gains China see from their strides into the region. In order to prove our hypothesis and research questions we've used econometric models.The panel data was used to conduct several time series regressions, where we further used different models and tests to get the best possible result Due to the fact that our regression shows a significant and positive correlation between economic growth in the region as a result of Chinese FDI, we can establish that past research is reinforced. Through the used model we’re enabled to look at the individual effects of every country in the region. In addition, by comparing these effects with the level of corruption and which type of income group the countries belong to, we can further highlight the fact that China tends to invest in countries who can offer something in return. Examples of such cases could be South Africa and Angola who are two of the biggest receivers of Chinese FDI in the region, which we, throughout the paper, attribute to the fact that they have an abundance of natural resources.

FN - stora ord, små handlingar : - En jämförande feministisk säkerhetsanalys av fredsoperationerna i Västsahara, Kongo och Sydsudan i förhållande till FN-resolution 1325 / UN - All Talk, Little Action : - A comparative female security analysis of the peacekeeping operations in Western Sahara, Congo and South Sudan in relations to UNSCR 1325

Nordberg, Filippa, Sundberg, Alva January 2023 (has links)
Women’s rights and female security is a growing concern in several conflicts around the world. In Congo, conflict-related violence has long been used as weapon and Congo has today become known as the “rape capital” beacuse of these war rapes. Further more, reports from South Sudan states that UN troops has ignored pleas for help by women being raped. United Nation Security Council Resolution (UNSCR) 1325 was implemented by the UN Security Council to combat conflict-related violence and add a gender perspective in UN Peacekeeping operations.  The aim of this thesis is to analyze the impact of UNSCR 1325 by comparing UN Peacekeeping operations’ mandates and actions before and after the resolution was implemented. The thesis will also analyse the UN’s action to eliminate conflict-based sexual violence and war rape. The peacekeeping operations that will be discussed are MINURSO (West Sahara) MONUSCO (Congo) and UNMISS (South Sudan). In order to do so, the theory of Female Security Studies [FSS] and Militarized Masculinity will be applied. In our thesis, the UN’s actions were found to be insufficient. The main factors resulting in this insufficiency was found to be the systematic failure to take the actions needed to implement UNSCR 1325, such as the increasing the number of female involvement in peacekeeping and peacebuilding processes. In large, the impact of UNSCR 1325 could have been bigger if the resolution had been implemented more efficiently. While the written changes were significant with the implementation of the resolution, these changes were not as visible among the actual actions taken in the peacekeeping operations in West Sahara, Congo and South Sudan.

Climate change adaptation in the Global South / Navigating complexity to build adaptive capacity and resilience to climate change in Northern Ghana

Dapilah, Frederick 06 May 2020 (has links)
Die Folgen des Klimawandels, sowie damit einhergehende Verluste und Schäden nehmen weltweit zu. Der damit verbundene globale Anstieg von Treibhausgasemissionen, zunehmende Verstädterung sowie ausufernder Konsum machen die Suche nach Anpassungsstrategien zur Vermeidung schädlicher Auswirkungen gegenwärtig wie zukünftig zu einer erheblichen Herausforderung. Diese erfordert ein tiefgehendes Verständnis der Komplexität vom Klimawandelfolgen für landwirtschaftsbasierte Existenzgrundlagen. Ziel dieser Arbeit ist es zu einem solchen Verständnis beizutragen. Die vorliegende Forschungsarbeit fragt daher danach, wie etwaige Umstellungsprozesse die Anpassungsfähigkeit sowie Resilienz der Bewohner_innen von Bagri, einem kleinen Dorf im Norden Ghanas, erweitern. Die Ergebnisse dieser Dissertationsschrift basieren auf empirischen Erhebungen, die zwischen Februar und Juli 2017 in Lawra District in Nordghana unter Heranziehung qualitativer Fallstudieninstrumente durchgeführt wurden. Zum Einsatz kamen semi-strukturierte Interviews, Fokusgruppendiskussionen, Umfragen sowie ethnographische teilnehmende Beobachtungen. Die so gewonnenen Daten wurden kodiert und mit SPSS (Version 20) kreuztabellarisch sowie anhand verschiedener Variablen ausgewertet. Außerdem wurden Häufigkeiten interpretiert und die Ergebnisse schließlich in Tabellen, Graphen und Prozentsätzen verarbeitet. Des Weiteren wurden inhaltlichen Analysen der qualitativen Daten vorgenommen, die es erlaubten, Muster und Themen aus den Interviews und Diskussionen weiter zu verfolgen. Die Resultate zeigen, dass die Bewohner_innen in der untersuchten Gemeinde über die letzten drei Jahrzehnte eine Reihe klimatischer Veränderungen mit negativen Folgen für die Landwirtschaft erfahren haben. Um sich beispielsweise an die klimawandelbedingte kürzere Dauer der Regenzeit sowie niedrige Niederschlagsmengen anzupassen, greifen Kleinbauern auf schrittweise Anpassungsstrategien wie verbessertes Saatgut und weitere unterstützende Maßnahmen zurück. Paradoxerweise, untergraben Klimawandelextreme derlei Strategien auf mehreren Ebenen und reduzieren Erträge um ein Vielfaches ihres Potenzials, was wiederum finanzieller Verschuldung Vorschub leistet. Die Ergebnisse dieser Studie zeigen daher, dass die Überwindung nicht-klimatischer Barrieren landwirtschaftlicher Anpassungsstrategien eine notwendige wenn auch nicht ausreichende Bedingung für eine erfolgreiche Umstellung darstellt. Immer neu aufkommende Schwierigkeiten machen Anpassung zu einem langfristigen Prozess. Eine zweite Erkenntnis dieser Arbeit ist, dass die sich wandelnden klimatischen Verhältnisse zu einer Diversifizierung der Lebensgrundlagen weg von landwirtschaftlicher Produktion hin zu Aktivitäten jenseits der Höfe in Bagri geführt haben. Die Ergebnisse zeigen, dass der Prozess der Diversifizierung abhängig ist von der Einbindung der Haushalte in Gruppenaktivitäten sowie in formelle und informelle Netzwerke. Zusammenfassend gilt, dass Haushalte, die engmaschig in soziale Netze eingebettet sind eine höhere Resilienz gegenüber wahrgenommenen klimatischen Veränderungen aufweisen. Dies liegt darin begründet, dass sie zumeist über einen besseren Zugang zu kritischen – materiellen wie immateriellen – Ressourcen verfügen, welche Diversifizierung maßgeblich ermöglichen. Zudem deuten die Befunde an, wie Gruppenaktivitäten und soziale Netzwerke Marginalisierung und widersprüchlichen Ressourcenumgang befeuern können, die zugleich die Gefahr bergen, soziale und ökologische Resilienz im Dorf zu verringern. Darüber hinaus zeigt diese Arbeit die Mechanismen kollaborativer Anpassungssteuerung auf, indem sie den Fragen nachgeht, warum und wie diese Steuerungsformen Anpassungsfähigkeit befördern. Die Ergebnisse verweisen auf die Beziehungsdynamiken zwischen den relevanten Akteuren sowie Nutzen und Misserfolge und die Herausforderungen nachhaltiger kollaborativer Anpassungsstrategien in Nordghana. Ergänzend, stellt diese Studie heraus, wie machtvolle Akteure Agenden setzen, Problematisierungen generieren sowie Regeln und Anreize schaffen, die im Widerspruch zu den normativen Grundsätzen der kollaborativen Anpassungstheorie stehen können. Ausgehend von der Fallstudie in Nordghana stellt diese Arbeit auch Überlegungen dazu an, wie kollaborative Anpassungssteuerung erfolgreichen Umgang mit klimawandelbedingten Veränderungen weltweit befördern kann. Zusammenfassend, leistet diese Arbeit einen Beitrag zur Schließung theoretischer wie empirischer Wissenslücken im wachsenden Bereich der Forschung zur Anpassung an den Klimawandel. Sie illustriert darüber hinaus den unschätzbaren Wert qualitativer Fallstudien und zeigt auf, wie diese einen Beitrag leisten können zu oftmals abstrakten und schwer fassbaren Themen in der wissenschaftlichen Diskussion und damit ein Fundament für informierte politische Entscheidungen sowohl auf lokaler als auch globaler Ebene legen. / Climate change impacts, related losses and damages are increasing globally. When these consequences are coupled with increasing global greenhouse gas emission, urban expansion and unsustainable consumption, the pursuit of adaptation to avoid adverse outcomes is a present necessity and a significant future challenge. The overarching aim of this doctoral dissertation is to gain a better understanding of the complexity of climate change impacts on agricultural livelihoods and how adaptation processes enhance adaptive capacity and resilience in Bagri, a small village in northern Ghana. The results presented in this doctoral thesis are based on empirical data obtained between February and July, 2017 in the Lawra District of northern Ghana using qualitative case study research methods: semi-structured interviews, focus group discussions, survey and ethnographic participant observation. Data from the survey were coded and inputted into Statistical Package for Social Scientists (SPSS) version 20 and cross tabulation and analysis of different variables and interpretation of frequencies were done and processed into tables, graphs and percentages. Content analyses of qualitative data were done which allowed patterns and themes in interviews and discussions to be derived and interpreted. The findings show that, people in the studied community have experienced a range of climatic changes with negative impacts on agriculture in the last three decades. In order to adapt to the short duration of the rainy season and low rainfall amounts associated with climate change, smallholder farmers use incremental adaptation strategies such as improved crop varieties and other support strategies. Paradoxically, however, climate change extremes (CCEs) undermined these strategies in several instances, causing crop yields to fall short of their actual potential leading to financial indebtedness. The results therefore, showcase that surmounting non-climatic barriers to the uptake of agricultural adaptation strategies is a necessary but not sufficient condition to achieving successful outcomes, as new barriers in the adaptation process beyond uptake are constantly emerging with CCEs being one example. Secondly, the findings show that climatic changes have necessitated livelihood diversification away from crop production and into off-farm and non-farm activities in Bagri. The results highlight how the process of diversification is dependent on household participation in various group activities and formal and informal social networks. Generally, households in dense social networks were found to be more resilient to perceived climate changes because they had access to the critical resources (material and non-material) essential for diversification. Importantly, the findings shed light on how group activities and social networks can create marginalization and conflicting resource use with the potential of undermining social and ecological resilience in the village. Moreover, this dissertation explores the mechanics of collaborative adaptation governance (CAG) addressing questions of why and how this mode of governance facilitates adaptive capacity. The findings illuminate stakeholder relational dynamics, benefits and failures, and the sustainability challenge of collaborative adaptation governance (CAG) in northern Ghana. More importantly, this study unveils how powerful actors set the agenda, frame problems, and implement rules and incentives contrary to the normative tenets of collaborative governance theory. Ultimately, the results highlights the failures, successes and sustainability challenges of CAG in northern Ghana, while also providing insight into the extent to which CAG approaches can facilitate adaptation to climate change globally. In conclusion, this doctoral dissertation responds to both theoretical and emperical knowledge gaps in the burgeoning climate change adaptation research, and illustrates how invaluable, qualitative case studies can contribute to illuminate some of the elusive themes in the literature and provide evidence for policy making at both local and global levels.

Advancements in Isotopic Geolocation Tools for Insect Migration Research

Reich, Megan 18 January 2024 (has links)
Migratory insects are vital components of global ecosystems and provide important ecosystem services, yet the migration phenomenon is understudied in insects compared to vertebrates. In this thesis, I aim to deepen our understanding of insect migration, using the monarch butterfly Danaus plexippus (L.) and the painted lady butterfly Vanessa cardui (L.) as model systems. Studying insect migration is notoriously difficult given the small size, high abundance, and short lifespans of insects. Isotope geolocation has shown promise for overcoming these obstacles. Here, I develop and apply metals and metal isotopes, specifically strontium isotope ratios (⁸⁷Sr/⁸⁶Sr), to increase the spatial precision of isotope geolocation and demonstrate how isotopic geolocation tools can advance our understanding of insect migration at the population level. In the first chapter, I test the validity of using ⁸⁷Sr/⁸⁶Sr, lead isotopes, and a suite of 23 metals and metalloids to estimate the natal origins of migratory insects, by investigating the pathways of metal incorporation into butterfly wing tissues. Using an 8-week diet-switching experiment, I show that the concentrations of many metals in insect wings can be altered through the adult diet or dust deposition, making them poor candidates for geolocation but potentially interesting tools to study insect physiology, diet, or toxicology. For example, lead was found to accumulate on butterfly wings from external sources, and lead isotopes could potentially be used to quantify the exposure of migratory insects to metal pollution. Some metals, including Ba, Cs, Mg, Na, Rb, Sr, Ti, Tl, and U, are good candidates for developing geolocation tools. I focused on ⁸⁷Sr/⁸⁶Sr and demonstrated that, despite some caveats, this tool is valid for isotope geolocation. In the second chapter, I outline the steps required to use ⁸⁷Sr/⁸⁶Sr for the geolocation of insects, including the calibration of a spatial model of isotopic variation (i.e., an isoscape) using random forest regression. I then combine hydrogen isotope values (δ²H) and ⁸⁷Sr/⁸⁶Sr into a dual assignment framework to estimate the natal origins of a single generation of monarch butterflies in eastern North America. I demonstrate that combining these two isotopes provides a more spatially constrained estimate of natal origin than using either isotope alone. In the third chapter, I apply this framework to characterize the migratory patterns and migratory connectivity of an insect species across a geographical barrier, the Sahara. Painted ladies journeying northwards across the Sahara appear to do so in a gradual progression, although spatiotemporal sampling limitations prevented a complete characterization of this movement. In contrast, painted ladies migrating southwards appear to journey in a broad front, parallel migration pattern with little longitudinal movement. Evidence for a leapfrog migration pattern was found in the western region, wherein butterflies of northernmost origin journey farther south than butterflies bred in more southerly regions. This leapfrog migration pattern suggests distinct migratory behaviours within painted lady butterflies wherein some individuals migrate longer distances than others. In the fourth chapter, I apply isotope geolocation to characterize the migration distances of multiple individuals and assess the potential genetic differentiation of butterflies migrating distinct distances. I use δ²H and ⁸⁷Sr/⁸⁶Sr-based geographic assignment to confirm that some painted ladies migrate up to 4,000 km from Europe to sub-Saharan Africa, while others migrate shorter distances from Europe to the circum-Mediterranean region. Despite these differences in migration distance, genome-wide analysis revealed a lack of adaptive variation between short- and long-distance migrants. Instead, variation in migration distance in painted lady butterflies is likely the result of a plastic response to environmental conditions. Overall, the methodological developments presented in this thesis are a step forward in studying insect migration. The development and application of metals and metal isotopes for insect geolocation opens new avenues to study the migration phenomenon at different scales with widespread relevance for conservation and pest management.
