Planning for Resilience in Small Towns of Ethiopia: The Metabolism of Food and Housing Materials in Amdework and BuraNEST

Tola, Teshome Tefera 02 April 2020 (has links) (PDF)
Contemporary towns and cities in developing countries are faced with myriads of challenges. And, scholars have been suggesting various approaches, methods and tools to improve local resilience against these challenges. Some of the approaches and movements that proliferated recently in urban studies are Urban Metabolism, Sustainable Spatial Planning, the specified resilience approach, and the circular economy. Although these movements played an important role in improving local resilience and sustainability in the western world, their impacts on towns and cities of the developing world remains minimal. This is mainly because these movements were conceived and born in western countries and most of them are targeted at solving their own local problems. So, there is a very strong need to contextualize and modify them so that they fit into the existing local conditions in towns and cities of developing countries. In addition, lack of institutions and usable data makes it very difficult to undertake similar studies in countries like Ethiopia. That is why contextualizing these movements and searching resource efficient paths to local resilience and sustainability have become important tasks in recent years. In addition, developing a methodology that helps to operationlize and spatialize these concepts (resilience and sustainability - concepts usually criticized for being too general and normative) is also very crucial.This research, therefore, developed a robust diagnostic and analytical tool to study the nexus between major challenges (in small towns) and their impact on local resilience and sustainability in Ethiopia. The urban metabolism approach is mainly used (as a tool) to understand the nature of these challenges and to diagnose resilience in small towns. It specifically focuses on the flow food and housing construction materials (the two most stressed flows) in the case towns. These case towns are selected to represent the two ends of the sustainable town planning continuum in Ethiopia (Amdework is an organically growing old town and BuraNEST is a new planned town based on principles of sustainability). This research is mainly conducted at three stages: at regional level, at local level and at sub-system level. The first task done to achieve this objective is, therefore, characterization of the role of the case town in the regional urban system. This is done mainly using the urban metabolism approach. The deployment of this tool helped the researcher to pinpoint weak links, unsustainable flows, and vulnerable paths that simultaneously impact local resilience and sustainability in the case towns. This preliminary exploratory research clearly indicated the role of the town in the regional urban system and revealed the two most stressed (but important) sub-systems in the localities: the food and the housing sub-systems.Following this preliminary finding, the research has been narrowed down to the aforementioned two most stressed sub-systems. The food sub-system is first studied using the urban metabolism and the 'specified resilience' approaches. The research adopts a tri-tiered method (resilience at the source, resilience in the chain and resilience in consumption) to investigate local food resilience and metabolism and their relationship with the spatial configuration of the case town. The deployment of this method helps to operationalize and reduce the normative content of the concept (of resilience). This study reveals that urban agriculture is a highly marginalized agenda at all the three stages. Furthermore, the research investigates various bottom-up informal initiatives in the case town and other innovative planning endeavors (such as the planning of BuraNEST) that are aimed at improving sustainability and resilience in the food sub-system. The other focus area of the research is the housing sub-system. The urban metabolism approach, again, is primarily used to characterize, map and quantify the flow of materials used in the construction of residential houses in the town. The research developed a new bottom-up data generation technique to undertake this analysis. This method dominantly relied on estimations and conversions (of traditional measurements to the metric system) to get quantified data that was finally used as an input to develop metabolic models. Models (Sankeys) developed in this research reveal that the vast majority of inputs used in the construction are sourced locally. However, certain recent worrisome trends challenging sustainability have been observed in the housing sub-system due to the increased tendency of transporting important construction inputs from distant sources (mainly due to local construction regulations). The research, on the other hand, found that housing in BuraNEST, a town claimed to have been planned based on principles of sustainability, is more reliant on local sources and recognizes local needs and challenges. However, there are some critical pending questions (related with governance and affordability) that need to be addressed to improve sustainability in the housing sub-system in the long-run. Lastly, the research also investigates planning system challenges in small towns of Ethiopia. This is done mainly because many of the challenges found in the previous two analyses point to the presence of certain systemic problems in the policies, laws and manuals used in the planning of small town of Ethiopia. Such disorientations obviously negatively impact local resilience and sustainability in the long-run. Various definitions, wordings, phrases, and criteria identified in the federal planning law and manual were found to be on a direct collision course with principles of sustainability in many instances. By doing these, this research, therefore, systematically analyzed how the nexus between population pressure, resource flows and planning system challenges impact local resilience and sustainability (in the food and housing sub-systems) in small towns of Ethiopia. More importantly, it successfully spatialized and operationalized critical concepts such as urban resilience and sustainability using a new bottom-up approach. Clarity of the methodology vividly spells out the starting point when dealing with such important topics. This research can, therefore, serve as an important material to other researchers who are interested to study issues related to urban resilience and metabolism in small towns of developing countries. It clearly shows how the urban metabolism (as a tool) can be deployed to diagnose resilience in specific systems and sub-systems of towns and cities. It also provides a step-by-step procedure on how to generate data in data poor contexts and build metabolic models that can be used to study resilience in urban areas. / Les villes contemporaines des pays en développement sont confrontées à une multitude de défis. Les chercheurs ont suggéré diverses approches, méthodes et outils pour améliorer la résilience locale face à ces défis et parmi les approches qui ont proliféré récemment dans les études urbaines, nous pouvons citer le Métabolisme Urbain, l’urbanisme durable, l'approche de la Résilience Spécifiée et l'économie Circulaire. Bien que ces mouvements et ces outils aient joué un rôle important dans l'amélioration de la résilience et de la durabilité locales dans le monde occidental, leur application et leur impact sur les villes des pays en développement sont négligeables. Cela est principalement dû au fait que ces mouvements ont été conçus et sont nés dans les pays occidentaux et que, par conséquent, la plupart d'entre eux visent à résoudre des problèmes qui leur sont propres. Il existe donc un besoin important de contextualiser et d'adapter ces outils, mouvements et méthodologies pour étudier, comprendre et résoudre les problèmes des villes du monde en développement. En outre, le manque d'institutions et de données utilisables rend difficile la réalisation d'études similaires dans des pays comme l'Éthiopie. La recherche de chemins efficaces pour la résilience et la durabilité locale est donc une tâche difficile dans les pays en développement. De plus, il est très important de développer une méthodologie qui aide à opérationnaliser et à spatialiser ces concepts (résilience et durabilité, des concepts généralement critiqués pour être trop généraux et normatifs).Cette recherche a donc permis de mettre au point un solide outil de diagnostic et d'analyse pour étudier le lien entre les principaux défis et leur impact sur la résilience et la durabilité locale dans les petites villes d'Éthiopie. L'approche du métabolisme urbain est principalement utilisée pour comprendre la nature des défis urbains et diagnostiquer la résilience dans les villes concernées. Cette approche se concentre spécifiquement sur les flux des deux sous-systèmes les plus sollicités :les flux de nourriture et de matériaux de construction de logements. Les deux villes étudiées sont sélectionnées pour représenter les deux extrêmes du continuum de la planification urbaine durable en Éthiopie :une nouvelle ville planifiée (BuraNEST) et une vieille ville à croissance organique (Amdework). Cette recherche est organisée selon trois échelles :au niveau régional, au niveau local et au niveau des sous-systèmes. La première tâche effectuée pour atteindre cet objectif a donc été de caractériser le rôle de la ville prise comme cas d’étude dans le système urbain régional, en s’appuyant sur l'approche du métabolisme urbain. Le déploiement de cet outil a permis d'identifier les trajectoires non durables, les flux vulnérables et les activités qui ont simultanément un impact sur la résilience locale et sur la durabilité des villes étudiées. Cette recherche exploratoire préliminaire a clairement souligné le rôle de la ville dans le système urbain régional et a révélé deux sous-systèmes particulièrement sous tension: les sous-systèmes de l'alimentation et du logement.Suite à cette première constatation, la recherche se concentre sur ces deux sous-systèmes. Le sous-système alimentaire est d'abord étudié en utilisant le métabolisme urbain et les approches de « résilience spécifiée ». La recherche adopte une méthode suivant trois niveaux (résilience à la source, résilience dans la chaîne et résilience dans la consommation) pour étudier la résilience alimentaire locale et sa relation avec la configuration spatiale urbaine. Le déploiement de cette méthode permet d’opérationnaliser et de réduire le contenu normatif du concept de résilience. La recherche révéle que l'agriculture urbaine est un programme très marginalisé aux trois stades du métabolisme alimentaire. En outre, la recherche examine diverses initiatives informelles ascendantes dans la ville en question et d'autres initiatives de planification innovantes (telles que la planification de BuraNEST) qui visent à améliorer la durabilité et la résilience du sous-système alimentaire.Le second domaine d'étude de la recherche concerne le sous-système du logement. L'approche du métabolisme urbain est utilisée pour caractériser, cartographier et quantifier le flux de matériaux utilisés dans la construction des bâtiments résidentielles. La recherche développe une nouvelle technique de génération de données ascendantes pour entreprendre cette analyse. Cette méthode repose principalement sur de nombreuses estimations et conversions (des mesures traditionnelles vers le système métrique) pour obtenir des données quantifiées qui peuvent être utilisées comme intrants pour développer des modèles métaboliques. Les modèles (Sankeys) développés dans le cadre de cette recherche ont révélé que la grande majorité des matériaux intrants utilisés dans la construction proviennent de sources locales. Cependant, certaines tendances récentes inquiétantes remettant en cause la durabilité ont été observées dans le sous-système de logement en raison de la tendance croissante à importer d'importants éléments de construction provenant de sources éloignées (principalement en raison des réglementations locales en matière de construction). D'autre part, la recherche a révélé que les logements de BuraNEST, une ville qui déclare avoir été planifiée sur la base des principes de durabilité, dépendent davantage des ressources locales et considèrent les besoins et défis locaux. Cependant, le programme de logement de BuraNEST suscite d'importantes préoccupations en raison de la présence de quelques enjeux la gouvernance et l’économie de la construction des maisons, qui peuvent menacer la durabilité du programme à long terme. Enfin, la recherche s'est également penchée sur les problèmes liés au système de planification dans les petites villes d'Éthiopie. Cela est principalement dû au fait que de nombreuses questions relevées dans les deux analyses précédentes indiquent la présence de certains problèmes systémiques dans les politiques, les lois et les manuels utilisés dans la planification des petites villes d'Éthiopie. De telles désorientations ont évidemment un impact négatif sur la résilience et la durabilité locales à long terme. Dans de nombreux cas, diverses définitions, formulations, phrases et critères identifiés dans la loi et les règles de planification fédérale se sont révélés être en conflit direct avec les principes de durabilité.Par conséquent, cette recherche analyse de manière systématique le lien entre la pression démographique, les flux de ressources et les défis du système de planification qui ont un impact sur la résilience et la durabilité des petites villes d'Éthiopie. Plus important encore, cette recherche a réussi à spatialiser et à opérationnaliser des concepts critiques tels que la résilience et la durabilité urbaines en utilisant une nouvelle approche bottom-up. La rigueur de la méthodologie définit clairement le point de départ lorsqu'il s'agit de traiter des sujets aussi importants. Cette recherche peut donc constituer un matériel important pour les chercheurs qui souhaitent étudier les questions liées à la résilience et au métabolisme urbains dans les petites villes des pays en développement. Elle montre clairement comment le métabolisme urbain, en tant qu'outil, peut être déployé pour diagnostiquer la résilience dans les systèmes et sous-systèmes spécifiques des villes. Il fournit également une procédure étape par étape sur la façon de générer des données dans des contextes de manque d’information ,permettant ainsi deconstruire des modèles métaboliques qui peuvent être utilisés pour étudier la résilience dans les zones urbaines. / Doctorat en Art de bâtir et urbanisme (Polytechnique) / info:eu-repo/semantics/nonPublished

Mai-Kadran Massacre and opposing narratives, The influence of Ethiopian Constitution, Religion and other Institutions

Antehunegn, Yihenew Alemu January 2022 (has links)
This research is about Mai kadra massacre that happened on Nov. 9 2020 during the Ethiopian National Defense Force law enforcement operation against the Tigray regional state. The massacre has ended with two conflicting narratives. This short research is therefore to clearly analyze secondary data collected (sources) against the two narratives of the massacre. Though there were difficulties to get as many documents as possible, the already collected data with some additional sources were used to answer the research questions and to give solutions for the research problems. At the beginning, this study presented the details of all the main documents to explain what claims about the Mai kadra massacre have raised. Secondly, claimed reasons about the massacre have discussed to answer one of the research questions (why the massacre has happened?) based on the secondary data collected and some other related documents. At last, the different themes formed have been analyzed against the two opposing narratives of this study. In relation to data analysis, thematic analysis under qualitative approach is used. Significant and essential theme ideas are drawn out from the data collected and organized in to different themes. All the themes are described and summarized according to their position about the two conflicting narratives in order to give clear information for readers. Opinions of the researcher are also added.

The assessment of Ethiopian Federal Police illicit drug trafficking prevention measures

Ayele, Moges Chekole 05 1900 (has links)
The Federal Democratic Republic of Ethiopia is located in the Horn of Africa and bound on the northeast by Eritrea and Djibouti, on the east and southeast by Somalia, on the south-west by Kenya and on the west and north-west by Sudan. In a 2003 report, the Ethiopia Central Statistical Authority (2003:24) estimated the population of Ethiopia to be 71,066,000. The Ethiopian economy is mainly based on agriculture, which contributes 47% to GNP and more than 80% of exports and employs 85% of the population. Ethiopia nowadays governs under a federal system and due to the governance system there are nine regional states in the country, which are composed of specific ethnic groups. The regional states, which have a significant degree of autonomy, are Tigray, Afar, Amhara, Oromia, Somalia, Benshangul-Gumaz, Gambela, Harar and the Southern Nations, nationalities and peoples, which comprise about 41 ethnic groups. Hence, the structure of the police service in the country follows the characteristics of the federal system. Accordingly, the regional states have their own police service, which is responsible to the regional states and at the federal government level, the Federal Police Service (FPS) is responsible to federal government. / Police Practice / M.Tech.

Balance-of-Power Theory and the Ethiopian-Somali Conflict of 1977- 1978

Ogundele, Ayodeji O. (Ayodeji Olusesi) 12 1900 (has links)
Balance-of-Power theory was tested by examining the 1977-1978 Ethiopian-Somali conflict and its outcome. The theory, according to Waltz (1979), claims to explain the international outcome arising from realpolitik or power politics, namely, the formation of balances of power. Given the close fit between the major developments leading to the eruption of conflict and the principal propositions of balance-of-power theory, the outcome of the conflict was expected to be consistent with that posited by the theory. This expectation was borne out by the study's finding which indicated that the conflict has produced a similar result. Confirmation of the theory was achieved by further subjecting the finding to the verification test established by Waltz.

Apatite Helium Thermochronology of the Blue Nile Canyon, Ethiopian Plateau

Blackburn, Nathaniel C 01 April 2016 (has links)
The Ethiopian Plateau, situated in the northernmost part of the East African Rift System, has been uplifted and incised by the Blue Nile River, creating the 1.5 km-deep Blue Nile Canyon, the only extensive canyon within the Nile drainage basin. Much of this canyon incision is related to the Ethiopian Plateau uplift, which is due to a combined tectonic influence linked to the East African Rift System and the Afar Mantle Plumerelated upwelling since the Oligocene. The Blue Nile Canyon incision followed this plume-related upwelling, which resulted in extensive flood basalt emplacement around ~30 Ma. This study employs low-temperature apatite (U-Th)/He thermochronology to better understand the timeline and mode of the Blue Nile Canyon incision and the landscape geodynamics of the Ethiopian Plateau. Neoproterozoic basement rocks and Mesozoic sedimentary rock samples were collected in a vertical transect along the Blue Nile Canyon for AHe dating. Euhedral apatite grains that are inclusion-free and fractureless were selected for dating. The Australian Scientific Instrument (ASI) Alphachron and Inductively Coupled Plasma Mass Spectrometer (ICP-MS) measured the concentrations of radiogenic isotopes uranium (U), thorium (Th), and helium (He) to obtain apatite helium (AHe) dates, providing (U-Th)/He cooling ages ranging from 64 to 460 Ma. These AHe dates are much older than the 30 Ma flood basalt event, thus older than the canyon incision. In this study, a cooling/thermal history is suggested by explaining the data dispersion by the radiation damage effect in the dated apatite grains, which is related to He retention with time. The apatite suite has been subjected to protracted cooling, longer residence time in the He partial retention zone, and partial resetting due to Mesozoic rift-related burial and subsidence from deposition of ~1.2 kmthick sedimentary rocks, the extensive emplacement of ~1 km-thick flood basalt at 30 Ma, and differential incision. Radiation Damage Accumulation and Annealing Model (RDAAM) time-temperature thermal models indicate a rapid cooling event, suggesting rapid incision after 10 Ma, which is explained by an increase in uplift of the Ethiopian Plateau, likely due to mantle delamination.

Community development initiatives and poverty reduction: the role of the Ethiopian Kale Heywot Church in Ethiopia.

Tefera Talore Abiche January 2004 (has links)
Ethiopia is a country well endowed with a number of development related NGOs who have been involved in socio-economic development at national, regional and grassroots level. In a country like Ethiopia, where natural and man-made hazards persist, NGOs play a crucial role in terms of reducing poverty and other human sufferings. As one of the non-governmental organizations, the Ethiopian Kale Heywot Church Development Program (EKHCDP) has played an important role in supporting and encouraging the development aspirations of local communities in the areas of environmental rehabilitation, water and sanitation, agriculture, health, education, credit and saving schemes.<br /> <br /> The study focused on the Ethiopian Kale Heywot Church community development program in five selected project areas, namely Lambuda, Durame, Shashamane, Debraziet and Nazret. The analysis subsequently examined the nature and extent of community participation in the project planning, implementation and decision-making phases. Thereafter, the study brought into focus general observations gleaned from the investigation and provides recommendation to the EKHC and other stakeholders that have been involved in development activities.<br /> <br /> Quantitative and qualitative methods of research have been applied throughout the investigation. Accordingly, observation, in depth interviews, focus group discussions and structured and semi-structured questionnaires were used to gather information. The qualitative mode was employed to gather socially dynamic information on issues relating to beneficiaries&rsquo / perceptions of processes in order to gain a deeper understanding of the dynamics at play. On the other hand, the quantitative mode was used to test variables related to the research problem. <br /> <br /> The findings indicate that the Ethiopian Kale Heywot Church development program has played a significant role in terms of community development. Moreover, its development approach is responsive to local needs and able to mobilize local and external resources to support the poor, so that through empowerment and participation they will be released from the deprivation trap that they find themselves in. The study also indicates that the EKHCDP has good linkages and networks with other communities and partners. However, the study indicated that the intensity of community participation in decision-making is still low in certain cases. Meanwhile, the beneficiaries did not show a clear understanding of aspects such as project ownership. Finally, this study recommends that genuine community participation should be maintained because it is the core activity contributing to beneficiary empowerment and grassroots institutional capacity building and an essential ingredient for self-reliance and project sustainability.

Amharové v Etiopii / Amharas in Ethiopia.

Zárubová, Martina January 2014 (has links)
The aim of this thesis is to present from the historical perspective the Ethiopian Amharas as a nation, which, even though they are not forming majority of the state, they had and still have major impact on the Ethiopian society. They also maintained influence on other nations mainly thanks to the Amharic language, which became the official language of the whole of Ethiopia. The structure of the work is divided in such a way in order to include all the relevant phases that are related to the history and life of the Ethiopian Amharas. The compilation of the work is based on the theoretical analysis and the study of the literature. In the thesis I give a brief overview of the history, including the legend of the origin of the Solomon dynasty, to which the Amharas still avow. In the view of the fact that significant role in Ethiopian society plays also the affiliation of most of the Amharas with the Ethiopian Orthodox Church, I deal with its history and hierarchies. I also apprise of the religious rituals, feasts and celebrations. In individual parts I follow up the historical roots of Amharic and its relevance to a particular language group. Role of Amharic is analyzed with respect to the educational system in Ethiopia, I am also referring to its role in connection with the so-called Amharization...

Understanding uplift of the Ethiopian Plateau from longitudinal profile analysis of the Blue Nile drainage system

Neupane, Prabhat Chandra 17 December 2011 (has links)
The Ethiopian Plateau is one of the few tectonically-active regions on Earth that is situated in continental rift zones. About 1.6 km deep gorge of the Nile was carved by the Blue Nile River on the Ethiopian Plateau, as the plateau has been experiencing continuous uplift and exhumation in the Cenozoic. Here, we used quantitative analysis of longitudinal rive-profile forms and parameters (knickpoint and normalized steepness-index ksn) of the Blue Nile tributaries to tease out regional tectonic signals. 244 knickpoints were examined in the tributaries, majority (>80%) of which are unassociated with lithology or geological structures. Knickpoint distribution throughout the plateau reveals three incision phases. The novel approach of correlation of ksn with mantle tomography suggests that higher and lower ksn values occur above low-velocity and high-velocity zones, respectively, indicating that thermal upwelling beneath the plateau linked to Afar mantle plume largely controls the uplift thus incision of the plateau.
