    Activities of common places in informal settlements: The case of selected streets and shared compounds of Abnet area, addis ababa
    (Addis Ababauniversity, 2016-12) Sileshi, Metadel; Yitbarek, Elias (PhD)
    Researches were conducted on the housing issues such as physical condition, transformation, identity and so on. The importance of common places and their use as part of the activities that takes place and the significance of these activities for inner-city neighborhoods of Addis Ababa, however, were not given much weight. Thus, the main objective of the research is to explore activities of common places in one of these neighborhoods. To investigate this, a case study approach was selected, as it is the best fit for descriptive, explanatory and exploratory questions. Moreover, it is the most appropriate to collect data in a natural setting. Accordingly, qualitative data is collected in the form of semi structured indepth interviews, mapping, photography and notes from personal observations. The case area, Abnet, was chosen based on the fact that it‟s a dense inner-city informal settlement. The research focuses on streets and shared compounds of a neighborhood. The streets based on activities taking place and other geographical features, are sub divided into two main categories, namely access and nodal streets, and small neighborhood streets, which are more intimate serving mostly residents of immediate compounds. A total of ten streets and seven compounds were studied. Accordingly, the main findings are: activities can be classified into four major categories namely, business activities, recreational activities, household activities and Social/cultural activities. It was revealed that, overlap of different types of activities is a common scenario. The type of places the activities occupy are found to depend on the types of activities. The research strongly suggests that overlap of activities is useful for maximum utilization of space with other socio-economic and recreational advantages and that it should be fostered. When planning and designing common places there should be hierarch of common places and they should be planned in a way that they can accommodate layers of activities

    Application of Curb Extension for Sustainable Storm Water Management of Local Streets in Water Logging Lands:The Case of Residential Areas in Addis Ababa:
    (Addis Ababa University, 2021-02) Beyene, Tsega; Assefa, Alazar (PhD)
    The application of sustainable stormwater management system in waterlogging areas of urbanized catchments is the most effective method that helps to control surface stormwater runoff caused by recurrent and extreme rain events. Applying a bio-retention system for flood reduction through infiltration and evapotranspiration processes will help to create an attractive urban street with better environmental performance. Since cities are becoming more impervious, the stormwater runoff increases and will affects the downstream land and water bodies by flooding. In Addis Ababa, applying a sustainable stormwater management system is a timely act due to the ongoing rapid urbanization and increment in impervious surfaces that result in stormwater runoff that causes flooding and surface water pollution. In this regard, innovative and flat terrain considerate design responses are needed in low-lying plains with difficulties to apply conventional pipe-based drainage systems. The design intervention will reduce the waterlogging effect occur due to extreme rain events. The objective of the research is to apply curb-extensions as a bio-retention system for sustainable stormwater management of waterlogging local streets in the low-lying residential areas of Addis Ababa. Specifically, the study identified areas affected by peak stormwater flow that creates a waterlogging problem over local streets of the case study area. A sustainable design solution is proposed by considering the infiltration, retention, and evapotranspiration capacity of curb-extensions. The study identified flooding and waterlogging areas in the city, at the river catchment, and in the study, site using hydrological and spatial data. Using ArcGIS-based hydrologic analyst tools, blue spots located along the flow direction of the streams identified as depressions usually experienced an overflow of stormwater and waterlogging. To minimize the risk of waterlogging, a sustainable design solution as a curb extension system designed by estimating the water balance from the actual water holding capacity of natural depression (blue-spot) and the stormwater runoff generated from the catchment area that naturally drained into the specific blue-spot. The curb-extension system was designed as a bio-retention and streetscape element by modifying the native soil, gravel fill, water intake plants on the top of the system for infiltration and retention purpose. In this regard, the designed curb extension will substantially manage the highest intensity of precipitation (40 mm/hr) of 10 years of rain event from IDF curve of Addis Ababa. The design reduces the volume of stormwater runoff from 22.895 m3 to 8.477 m3, which is 62 % of runoff. The study concludes that if the municipality of Addis Ababa develops a curb extension system over the local streets of the entire neighborhoods affected by waterlogging, the flooding problem will be reduced substantially with more greening & environmental benefits. The system will also contribute to the reduction of downstream flooding by minimizing stormwater runoff flowing into the Akaki river system. As a multifunctional drainage design facility, the system has the potential to create a green street that helps to improve the standard of living and boost the environmental quality of the area. Finally, the study recommended further study on the upscaling of proposed curb-extension by developing more empirical and experimental settings as a pilot project. The pilot projects will help the city to consider the curb-extension system for the greening, drainage design, and urban planning practices. Moreover, the tests and demonstration works will justify its competency for improving the livability and livelihood of the local people within urban settings that were frequently affected by waterlogging.

    An assessement of household poverty in addis ababa: The case of two Kebeles in addis ketema sub-city
    (Addis Ababauniversity, 2015-05) yibeltal, Kidist; Tolossa, Degefa (PhD)
    As we all know urban poverty is one of the major problems of Ethiopia. The main objective of this study was to assess household poverty in Addis Ababa by taking two kebeles of Addis ketema sub-city. In order to achieve the objective of the study from the study population of 55,762 household heads 200 samples were selected through random sampling method. The study used both primary and secondary data sources. Data was analyzed and interpreted mainly through quantitative method and it was supported by qualitative method. The two dominant approaches of poverty analysis- income and welfare were adopted. Income and expenditure of the household were viewed from the perspective of household size, education, age, martial status, and employment. Welfare is also analyzed through the nature of the house (wall type, construction material for floor and material of roof), house tenure, renting, number of rooms, supply of drinking water, main source of light, use of kitchen, energy consumption, toilet, bathing facility, and health condition. Coping strategies like saving, aid, migration, and cutting down meals per day were identified in the study. The result of the study in general showed that households in the selected areas have quite low income and most of them depend on one source of income. 51.9 percent of the surveyed population is employed themselves in petty trade. 32.5 percent of the households earn with a gap of 401-700 per month. More than 34.4 percent of the households’ income couldn’t cover their monthly expenditure. Divorced and widowed which accounted 22.5 and 19.0 percent, respectively, sections of the society experience more poverty than those who are not. Besides, 40.0 percent categorized themselves as very poor when compared with other community. Most of the respondents (50.0 percent) have experience of food shortage and out of this food insecure households (50.9 percent) of the respondents use cutting down the amount of their meal (frequency at two times per day is a dominant means) in order to cope up the food shortage. Based on the findings, the study recommended that investment on infrastructure is highly recommendable for the problems like housing shortage, overcrowding, rents affordable relative to income and the quality of houses. Health coverage, water and sanitation facilities also need to get immediate attention by the development sector

    Assessment of Intervention and Influence of Urban Redevelopment on Architectural Heritages Located in Arada area
    (Addis Ababa University, 2019-11) Shawul, Biniam; Girmay, Tadesse
    Conservation of urban and architectural heritage in the Arada area is basic to remember the history of Addis Abeba. Currently, the city is experiencing redevelopment activities. The research was assessing urban redevelopment interventions and influences on architectural heritages, for the case of main Street of Churchill and the surroundings. The significance of the study is to conserve architectural heritages from mass destruction due to urban redevelopment. The research was conducted through site investigation, document analysis, interviews and questionnaire surveys. Both qualitative and quantitative data are collected from different sources. The research is mainly qualitative. The quantitative data collected is used to support the results but not as a major source of data or information to reach a conclusion. The research was done through identifying independent factors that affect architectural heritages such as problem of urban heritage management, professional gap, redevelopment, improper structural intervention and natural factors deeply investigated from site investigation and interviews. The research identifies that architectural heritages are vulnerable due to urban redevelopment and lack of understanding the value of heritage. Due to this, the historic buildings were transforming their existing character into modern buildings; In addition, they are missing its historical values. The research would recommends the policy developers and community should be work together to increase the property value of a Arada area. Generally, the study shows that to conserve the architectural heritage located in Arada area, the stakeholders shall be work on revitalization, adaptive re-use, restoration, and renovation.

    Assessment of the effects of decentralization on urban service delivery: case study on education and health services deliverance at Debre Markos town, Amhara National Regional State
    (Addis Ababauniversity, 2011-05) Muktar, Mahmud; Abebe, Mulugeta (PhD)
    In Ethiopia rapid urbanization is the product of socio economic development. As a result urban populations have been growing in an alarming rate. This situation mainly aggravated by the two major features: rural-urban migration and natural increase of the population. Due to these demographic changes, pressure put on urban centers in which residents hardly get quality and efficient services. To tackle down such urban problems, the GoE has established decentralization policy that aimed to transfer powers, responsibilities and resources from the central government to regional, zonal, and Wereda levels of administration. This research has given emphasis on education and health service delivery in Debermarkos town case. In this town basic services provision intricate with social problems: inadequate and poor quality of services, less accountability and transparency, insignificant number of professionals, low institutional capacity and minimum public participation in planning, monitoring and decision making process. But these poor conditions of service providers of had not been assessed or studied (i.e. academically); it couldn’t be identified, determined, evaluated and recognized the hindrance for effective implementation of decentralization at the district level. The research used qualitative and quantitative data. This study has assessed the local service providers’ performance in line to quality indicators and the governance values indicators: accountability, transparency and community involvement in the improvement and provision of services. From the findings, it concluded that that decentralization obviously shown improvement in service delivery particularly in schools’ and health centers’ service delivery activities: service providers could perform their duties with autonomy, improve quality and efficient services delivery. However, administrative constraints: clarity of responsibility, accountability, open information flows, and participation have made the services provisions inadequate. The paper suggests that public service providers should be participatory, transparent (free access to information), empowered to decide administrative issues autonomously, accountable to the community, dynamic to identify community interest and should include community input in strategic planning and decision making process in the public service providers. Key words: decentralization, autonomy, accountability, transparent, participation, social service: education service, health service

    Assessment of urban plan and design implementation and management in ethiopian secondary towns:
    (Addis Ababauniversity, 2012-11) Dukale, Yohannes; Wogayehu, _Fisseha (PhD)
    Planned urban development is a phenomenon recently getting a wide acceptance throughout the country in genera and in the study town in particular. Following this fact, Dilla town had been prepared plan for two distinct times (1967 by Italian consultant and 1998 by NUPI). However, when we examine its implementation and management rigorously in the real ground the situation is bounded with a number of problems. When superimposing this to Dilla's current situation in which the town stayed for a half decade by implementing dated out development plan (envisaged to serve only ten years 1998-2008); it could not be exaggeration to one to say urban developments are held without proper or fully consideration of plan. Furthermore, none of the time the implementation, performance and management of the stated plans has been evaluated and monitored. The ultimate goal of urban plans and designs lies in its successful implementation. Urban development without pre-planned activities causes a mess of urban problems, and laissez-faire development having long term repercussions. This research is attempted to exploited the real problems pertained in Dilla town plan/design implementation and management, and then pin points the better means that can potentially foster the socio-economic development of the town. The research work approached with explaining the identified gaps while planning periods. Then after brief descriptions both qualitatively as well as quantitatively employed to describe and provide magnitude of the problems. These are performed through direct on spots observation of the implementation trends, interviewing the direct beneficiaries those believed to have exposure to the issues under study. Spatial physical plan documents like land use, road network, local development plans, etc and reported documents like text summery while plans prepared, municipal reports related with plans and designs implementation and administration have been engaged as a main methodologies for the development of the entire study. Even though, there exists fragmented efforts to guide the socio-economic development of Dilla town in various periods and persons it is found out that the overall performances of plan and design implementation and management is held with bundles of problems. The majors among many are: Institutional capacity of implementing bodies mainly connected with poor documentation of the plan resources, shortage of plan/design making and implementing professionals, skill gaps of available human/personnel resource, shortage of equipments and facilities required for planning and implementation process, shortage of financial capacity and proper utilization of it. Gaps during planning process, absence of means for facilitating implementation, absence of plan monitoring, evaluation and updating trends, absence or lack of stakeholder participation and interference, presence of areas where the boundary till not well delineated, presence of 6 rooms for illegal/informal settlements, are real and major upfront problems among many in the context of Dilla town. Finally, all stake holders at various levels to be equipped with full information about these problems mention here above and had to give especial attention and the clients critically establish unique means and strategies to follow-up and ascertain:  Use of up-to-date and recent map information and aerial photo for the acquisition of accurate topographic maps and existing realities;  Conduct and properly forecasted socio-economic linkages study from all possible influential areas;  Consistency of Graphic/spatial representations with implementation strategies, planning goals, objectives and text report;  Ways how public participated and reverse/rectify the immediate mistakes of implementation;  Production of all relevant documents of planning processes in hard copies and in soft copies during planning as well as implementation period. Particularly, zonal administers/city governors/Dilla municipality critically examines and ascertain periodically:  Weather the city had had and under-go in accordance with development plan;  Monitor professional, managerial, financial, technical, equipments, etc capacity and situation and then adapt oneself in accordance to expected output and potential of the city

    THE AURAL PRIVACY OF MIXED-USE RESIDENTIAL BUILDINGS IN ADDIS ABABA: THE EFFECT OF COMMERCIAL UNITS ON AURAL PRIVACY OF RESIDENTS OF GOTERA CONDOMINIUM
    (EiABC, 2019-06) URGESA SEIFU, TILAHUN; IMAM, MAHMOUD HASSEN
    Condominium housing project is started to accommodate the housing problem in Addis Ababa. Mass housing development approach has different problem on resident quality of life as compared to other development approach due to mixed land use development and one of the sole indicators in housing quality is that of privacy or “privateness” . The objective of this study is to explore the level of aural privacy in mixed residential building of condominium neighborhood. Therefore, the oldest phase of Integrated Housing Development Program (IHDP); Gotera condominiums is selected for this study. To have desired information from respondentsabout the impact commercial unit on their aural privacy survey method were used.Structured, semi structured interview and measurement is conducted to get quantitative data, and beside this the qualitative data was collected through physical and spatial analysis of the selected site. in addition to this; Standards, documents, research papers, books, maps, reports, proclamations are used by the researcher as a secondary source. Research questions are designed to find out how and to what extent commercial units affect resident aural privacy in terms of unit characteristics. In addition to this coping mechanism by residents and management component by different officials towards aural privacy is the focus of this study. The results show that, residents of mixed residential buildings are highly affected by noise pollution from specific commercial units specially during sleeping time. The level of aural privacy of the residents are different based on spatial, physical, socio-economic and demographic characteristics. High level of noise pollution from commercial units has its own impact on resident’s health and day to day activity.To control high noise pollution from specific commercial units, vulnerable residents use different coping mechanisms, while noise pollution management by concerning bodies is weak due to lack of knowledge among officials, corruption, servility, ignorance, unorganized working structure. The study recommends four strategies to ease the residents from sound pollution in mixed residential buildings. Zoning within neighborhood design, typology design, clear management towards the noise pollution and finally further study toward this area are essential to increase the aural privacy

    BUSINESS PROPERTIES PARTIAL TAKING EXPROPRIATION FOR ROAD PROJECTS AND VALUATION FOR COMPENSATION:THE CASE OF TWO ROAD CORRIDORS IN ADDIS ABABA ETHIOPIA
    (EiABC, 2018) Dewisha, Haymanot; Eyasu, Kumera
    Urban upgrading and renewal programs require demolishing and reconstructing existing areas. Typically, these interventions require the public acquisition of assets and land with payment of compensation. Usually such acquisition of land involves two types of acquisition, partial and total acquisition of land. Each type of acquisition involves different principles and legislative provisions in assessing compensation. Similarly, in Ethiopia Land is presently being expropriated for roads, real estate development and other massive infrastructure developments.In this regard though different principles and methods are involved in assessing compensation with in partial and total land acquisition, sufficient researches are not carried out considering partial takings as a single entity.Studies generally focus on legal and administrative aspects than calculation of the compensation quantum of partial takings. Therefore, the aim of the study is to examine valuation and compensation practices in partial land acquisition of business properties for road projects. For this purpose, two case study areas are selected purposively. Primary and secondary data collection method used by using interviews, observation and document reviews as a tool. Qualitative and quantitative data analysis has been used to analyze this research and descriptive method of analysis has been used. The findings reveal that, for valuing properties for partial taking there are two different methods of valuation which are before and after and taking plus damage method of valuation. From which the appraisal problem for partial acquisitions is essentially a before and after process using either the "Federal Rule" or "State Rule". Then study adopts the before and after method using the income approach in analyzing the data obtained. And recommended the state rule to minimize claims and fairly compensate what has been taken from the owner.

    The case of Addis Ababa-along Ring Road from Bole Square to Megenaga Square
    (Addis Ababauniversity, 2010-06) G/Tsadik, Tewedros; Singh, Gurdeep(Professor)
    Cities are fascinating because, in our increasingly urban world, they are intimately tied into almost the complete totality of human life. This makes them such vibrant and exciting places in which to live and also to study. Today due to many reasons: Employment, Education, Health and other opportunities, people prefer to live in cites, and as such population increases in the cities. Providing of land for various activities and fulfilling the required services became the challenge of the Administration. To overcome these problems, proper utilization of recourses such as Land (Urban Vacant Land) plays significant role. In this respect the Urban Vacant Land Management and Development assures the development of the city in the positive direction. Land is intrinsically a social rather than a private commodity. Literature explains that, Vacant and abandoned properties present both a significant problem, and also an opportunity, for many central cities. As Vacant Land represents both a significant problem and an attractive opportunity for many central cities, Vacant Land imposes both economic and social costs on cities in general and the neighborhoods or districts in particular in which the vacant land is located. On the economic side, such properties lower neighboring property values and tax revenues even as they create pressure to raise taxes to maintain service levels. Likewise, vacant land imposes significant social costs on communities as images of blight, as targets for vandalism and criminal activities, and as such it is unsafe and unhealthy plot for residents. It is, therefore, the main objective of this study to investigate what hinders and what are the reasons for the under utilization of the existing Urban Vacant Land in Addis Ababa. The study has three major parts. The first part is the general part in which it discussed about the need for the study, its significance and the rationale behind this study. It also states objectives and scope of the study, limitation of the study and points that the study would like to investigate. The second part deals with the review of relevant literature. In this part the research reviewed books, study papers, relevant publications and discussed the concept of Vacant Land, its Types, Properties conditions and Characteristics in general globally and tries to present the concept of Urban Vacant Land rationally

    Challenges of urban plan implementation in small towns of Ethiopia: The case of Gelan town
    (Addis Ababauniversity, 2011-05) legesse, Habtamu; mahiteme, Yirgalem (PhD)
    The sudden establishment and eventual growth of Gelan town brought many urban plan implementation challenges that need to be investigated to minimize the spillover impacts of urbanization in Gelan town. Gelan town is established after the establishment of some investments and has been grown by displacing and affecting the livelihood of local farmers. The overall impacts of urbanization on the local farmers requires to look into the local ecology towards which Gelan town is expanding, role of investments operating in the area, the plan that guides development and future expansion. This research is an attempt to investigate the challenges of urban plan implementation in Gelan town with a particular emphasis on the livelihood of farmers, role of investments of the town to the local economic development and ground water resource of the area. Accordingly, to look into the issues I have used both qualitative and quantitative data collection and analysis techniques. Data collected through interviews, questionnaires and field observations were analyzed and presented through discussions, tables, figures and maps. The findings revealed that most investments and recreational centers before the establishment of Gelan are located along highway and occupy large blocks that hinder accessibility of land uses at the back. The ground water catchment area of Akaki partially within the planning unit of Gelan town. Intensive constructions taking place in the area is believed to have a negative impact on the ground water recharge of the area from where water is supplied to the population of southern Addis Ababa. The research also found out that farmers whose livelihood is based on farming are forced to change their livelihood strategies by renting farmland using money obtained through compensation. As a result, the livelihood of farmers is negatively affected. The analysis of Gelan town structure plan showed that the plan was implemented poorly and lacked plan evaluation, monitoring and updating taskforce. As a result, irregular and irrational development as well as incompatible land uses are common along Addis Ababa-Adama highway crossing the town

    Characteristics of Mixed Income Neighborhoods in Addis Ababa: The case of Aroge Kera
    (Addis Ababauniversity, 2014-06) Fantahun, Hellom; Alemayehu, Yonas
    This research is motivated by the existence of different mixed income groups in the city of Addis Ababa where segregation is not seen commonly. Thus, the main purpose of this research is to identify and analyze the characteristics of mixed income neighborhoods in older residential settlements of Addis Ababa. For this, major objectives such as: identifying the socio-economic and spatial characteristics, analyzing the factors and elements that brings mixed-character and investigating the problems and benefits of mixed income neighborhood was set. And case study methodology was used to test and understand real existed situation in a selected study area through primary and secondary data collection techniques. To test the existence of mixed income neighborhood in Addis Ababa, Aroge Kera area which is located in Arada sub-city, kebele 01/02 has been chosen for the case study. This area have been investigated in-depth with the life stories of high, middle and low income households based on formulated socio-economic filters such as: sources of income, household income, social interaction, job opportunity, participation in social activity, sharing of household equipment and services. Spatial filters such as: social service and infrastructures, house type, local road, public and private open spaces, compound characters were also used. Then, the data is analyzed both qualitatively and quantitatively. Quantitative issues were analyzed by graphs and descriptions, while qualitative issues were analyzed by maps, tables and descriptions that show comparison and relationships. The major socio-economic findings identified in this research are: the low income people benefited in getting job opportunity and financial support from the middle and high income people when facing problem. The high and middle income households get cheap labor from the low income residents during events like wedding, ceremonies, funeral by preparing injera, wot and tela. The major spatial findings identified for the existences of mixed income neighborhood are: different house types, private spaces, compound and availability of service for all income level residents. The house type based on area for high income is 120-180m2, middle income 60-100m2 and 15-3m2 for low income households. Compound and front yard for high income one household live in one compound, for middle income 3-6 households live in one compound and for low income 9-13 households live in one compound. As any other neighborhoods the research also identified problems in the neighborhood such as: shortage of children‘s playground, security problem, and the low income households are more affected by lack of common space in the compound. Based on these findings socially mixed design incorporating spatial elements is suggested and also recommendations and design proposal is forwarded

    Communal Buildings of Condominium Housing : The case of Gofa Mebrat Haile condominium, Addis Abeba
    (Addis Ababauniversity, 2015-06) Habtamu, Trusew; Yitbarek, Elias (Professor)
    Since 2004/5 the IHDP ( Integrated housing development programme) has been implemented by Ethiopian government to alleviate the sever housing problem in urban areas. The programme led to the development of condominium houses in Addis Abeba. The condominiums especially those built previously were G+4 walk up blocks with exterior stairs and circulation. These blocks came in contrast to the previous mud and single storey houses where majority of low and middle income group have lived with high attachment to ground level and traditional way of life. In order to make residents adapt to the new way of life and perform extensive household activities communal buildings has been introduced but this blocks had many problem around the management and use for communal purpose. In general the objective of this thesis was to investigate how the provision of communal buildings responded to the space needed for extensive traditional activities such as, slaughtering, hand washing clothes, drying clothes, spice drying etc. In order to achieve objectives of the study first the use and function of communal buildings has been studied. Second the thesis try to investigate to what extent are they being used. Finally how and where residents perform extensive household activities had been studied. In order to answer these questions three case study communal buildings were selected from Gofa Mebrat Haile condominium. The data have been collected from interviews with 45 residents. Furthermore interview with condominium association officials and gatekeepers has been conducted. The finding indicates that even though communal buildings are not given legally to residents still the buildings have been used for different function such as storage, office and shop. The condominium residents rarely use communal buildings in non-formal arrangements with the association but 75% of respondents had never used them at all. Furthermore the finding indicates communal buildings are not used for their intended purpose fully. Majority of the communal blocks are abandoned without clear responsible body which led to their current bad sanitary condition. In contrast to communal buildings resident use corridors and open spaces for extensive household activity which supposed to happen on communal buildings. Generally lack of strong administration and facility management has been also found. In order to achieve better living condition in condominium housing, communal buildings has to be maintained and used fully to betterment of the community. Increasing public participation through different mechanism and finally integrating communal facilities in condominium blocks based on the need and residents way of life should be considered in the design of condominium housings. Key words: Condominium Housing, Communal buildings

    Communal Facilities: A study on efficiency of communal building utilization in Public condominium housing Case Study of Selected Condominium Sites in Addis Ababa
    (EiABC, 2016-05) DAGNE, FITSUM SHAWEL; IMAM, M. HASSEN
    The provision of communal buildings to condominium sites is an attempt to respond to the cultural needs of residents, which is to provide a protected space for residents to perform traditional tasks. Although the provision of communal units is well intentioned, the post-occupation management and use has proven problematic and there remains no overall coherent approach to address it. This thesis investigates the efficiency of utilizations of such communal buildings. The main aim of this research is: to map out the overall conditions of communal buildings, to analyze the quality and performance of communal buildings and to discuss if communal buildings in condominium housing is an efficient option in responding to the socio-cultural needs of the residents and to make a recommendation. The phenomenon is investigated through the analysis of case studies located in three areas. The data are primarily collected through qualitative techniques supplemented by a quantitative technique. The investigation is carried out from the perspective of spatial use, management and residents response and perspective. Based on the empirical evidence from the case study the following findings are revealed. The study shows that there is a significant change in the design typologies of communal buildings in terms of size, layout or functional accommodations. Slaughtering room, laundry and stores are the common functions provide in communal buildings while some of the rooms in the communal buildings are still locked and unusable. In terms of spatial use, the finding reveals that slaughtering, cooking extensive meals, storing equipments , celebrations, commemorations and mourning are the activities undertaken in communal buildings. Because of inadequacy and lack of operative spaces, residents still perform other different or similar activities on alternative spaces such as open spaces, walkways and corridors. In management, proclamation 370/2003 serve as a legal basis for post-occupancy management of communal buildings. The study also found that most respondents uses the communal building occasionally and the slaughtering room is the most frequently used space. The findings of the survey result reveals that, the respondents were generally dissatisfied with the communal buildings; suggesting that the communal buildings are not meeting their needs and expectations to a reasonable extent. Generally, it is concluded that currently communal buildings in condominiums have a very large room of improvement for further fostering in design and efficient utilization. Major problems, related to both management and design of communal buildings, are revealed and their possible remedy is indicated. Provision of communal building compatible with residents culture, needs and expectations is suggested and design strategies are put forward that lead to a more flexible communal building design with versatile spaces.

    Communal Open Spaces in Condominium Neighbourhood: the case of Gofa Mebrat-hail Condominium, Addis Ababa
    (Addis Ababauniversity, 2016-01) alemayehu, Yonas; Mamo, Yonas
    The study investigates the relationships between physical characteristics of communal open spaces and the activities in residential environment of Gofa Mebrat-hail condominium neighbourhood, which is one of the project in Integrated Housing Development Program (IHDP) in Addis Ababa. The phenomenon is investigated through a case study research method by taking the neighbourhood as a case and aiming to study: a) how the residents are utilizing the communal open spaces by investigating the activities happening and the level of their involvement in terms of utilising these spaces; b) investigate and analyse the cause and effect relationship between the activities and the physical characteristics of existing open spaces and c) identify the challenges on the day to day activities of the residents as a result of the current conditions of communal open spaces. The study is conducted at two levels; first, a preliminary study was done covering the whole neighbourhood in order to study the activities, which are taking place on communal open spaces, and to select an illustrative parcel. Then an in-depth study is conducted on the chosen parcel based on the focus of the research to achieve the objectives. From the data collected through interviews, questionnaires, observations, and physical measurements, a qualitative and quantitative analysis are done: to examine the usage of existing communal open spaces; to understand the relationship between the physical setting of open spaces and the activities; and to investigate communal open space related challenges on the day to day activities of the residents. Results indicate that, despite availability of communal open spaces, physical attributes of the area investigated, such as adequacy of spaces, type of enclosure, location, accessibility and overall physical quality (attractiveness), when unsatisfactory, negatively affected residents’ attitudes and motivations to utilize and improve the space through physical changes and maintenance, and consequently affected social and user-environment interaction. Besides the physical attributes of the open space, the existing multiple activities are also a major factors that affect residents while utilizing the space. The other important finding is that the existing communal open space related challenges are found to be the result of combined effect of the physical characteristics and the existing activities. Finally, based on the findings the study recommends that the respective institutions who take part on developing communally owned residential neighbourhoods should make an in-depth observation to consider the need and the spatial aspect of communal open space during planning & implementation stage. The study also recommends post-occupancy resolutions to improve existing condition of communal open spaces on the study area. Key issues: IHDP, Activity, Communal Open Space

    Real estate product by its nature is heterogeneous and its value is the combination of the integrated components of the property, amenities, and externalities which may be positive or negative but, these determinant variables are not studied sufficiently in Ethiopia. This study is conducted on the comparison of monthly rents for private and government-administered residential apartments in Addis Ababa, the capital city of Ethiopia, at three case study areas, CMC, Jemo and Kazanchis on 164 sampled private residential apartments and 150 government-administered residential apartments. The sites CMC, Jemo and, Kazanchis were selected purposefully for the existence of concentrated comparables and completion of constructions of real estates in those areas. The samples were selected purposefully to include variations in floor levels, the number of bedrooms, access to lift, the number of bathrooms, external wall finishes types and better views. These variables are included at each floor levels. The monthly rents of private residential apartments are collected by questionnaires from the tenant and the monthly rents of government administered residential apartments were taken from the federal housing corporation. Based on the data, the average monthly rents of one, two and three bedroom of government-administered residential apartments for both diplomat and the local tenant is smaller than the monthly rent of private apartments. The rent of government-administered residential apartments is determined by the advanced regulated procedure. Based on the regulation and actual estimation of rents, quality of property to be rented, the internal area of the property, tenant type (as local and diplomatic ) and Site level that the property exists are the main determinant variables for government-administered residential apartments. The regression result of private residential apartments at the case study areas indicate as nine significant variables (Area of the apartment, Acces to balcony, Security of the compound, Access to type of road, Access to parking area, Number of bedrooms, Access to lift, Type of external wall finish and the Location of the site) that determine the monthly rent at the 95% level of confidence interval. Monthly rents should be determined in relation to the coefficients of these significant variables with the developed model. In comparison to the private residential apartments, the government administered residential apartments are rented at lower amounts and it is static. The monthly rent of private residential apartments increases in each contractual agreements and tenants rise this issue as their problem. It is not to say there should be static rent, but the increasing rate is high. To solve this challenge of the tenant, there should be a guide on landlord-tenant relationships. From the highest and best use perspective of real estate, the government administered residential apartments are rented at the lower value. To solve this problem, the government should either privatize or adjust the rent at least not to be static.

    Condominium Buildings Versus Environmental Sustainability In the case of Addis Ababa Advisor:
    (Addis Ababauniversity, 2014-05) Seife, Netsanet; Worku, Hailu (PhD)
    The growth rate of Addis Ababa’s population has resulted in a chronic housing problem expressed in the growing slums, unsanitary living conditions and a degraded environment. The Integrated Housing Development Program (IHDP), also known as the condominium housing project launched by the government in addressing this problem, even though it stands to save the city of worse environmental deterioration, has used the open and green spaces of the city; and being solely directed to solve the housing backlog, may lack environmental sustainability initiatives. In general therefore, the objective of this study is to present the concept of environmentally sustainable buildings, to study ways it has been and can be implemented and to adapt these concepts to the condominium project. To accomplish that, three sites – the Bole Gerji, the Feresbet and the Mickey Leland – were selected as case study samples. To gather data, interviews with the dwellers at the sites, observations of the site and a review of different researches and relevant literature on environmentally sustainable buildings were conducted. The data gathered using these methodologies was then analyzed and interpreted and used to develop a proposal of what could be done to include environmental sustainability concepts in the design and construction of the condominium project. The questions asked in the interviews were designed to discover how aware of environmental issues such as global warming and climate change the dwellers were. The results show that though dwellers are educated and aware of the issues of global warming and climate change, they have not taken the most optimal environmental sustainable measures they could; i.e., the long-term impacts of the measures taken to meet their immediate needs, such as parking, are not taken into consideration. The results from the site observations show that most open spaces are not used according to the original design; that the design was lacking in areas that could contribute positively to good indoor air quality and to the health and comfort of the dwellers; and that the materials used in construction are not durable. It is proposed that the condominium buildings should be designed, constructed and used incorporating environmental sustainable building concepts. Several propositions therefore are that additional sources of renewable energy other than hydroelectric power, such as solar power and biogas, be used and that water and waste should be recycled. In conclusion, it can be said that the Integrated Housing Development Program only addresses the need for housing and that environmental sustainability building concepts were not paramount in the design. After the sites were delivered to the dwellers, in general, it can be said that successful environmental sustainability concepts undertaken by them are limited to greening their immediate surroundings

    The Contribution of Built Forms and Landscapes in Creating Vibrant Street Life. Cases from CBD of Addis Ababa
    (Addis Ababauniversity, 2015-06) Hikma, Hikma; Yoseph, Ezana
    Urban planning and design have proven to be an important disciplines in shaping urban life styles, solving problems and giving new ways of living in the urban arena. There are a number of elements that manage the shape and the quality of urban environments. Quality of life in cities is affected by the negative and positive aspects of street activities and functions. The built form is one of the many variables thought to affect physical activity levels. It influences people’s lifestyles. Hence, believing the idea of creating good relationships between streets and their adjacent built forms is the main reason in creating better street life. The main objective of the research is to find out the impact of built forms and landscapes in creating vibrant street life. Therefore; the research analyses the Contribution of Built Forms and landscapes in creating vibrant Street Life by assessing different segment of streets found in the core of the city of Addis Ababa which believed to have a uniquely useful character aiming to learn from existing attributes, identify the gaps, and come up with a contextual urban design recommendations that help to create and maintain a vibrant pedestrian street life in order to make people feel friendly with streets and have some sense about the street they use more than having a concept of considering them as a corridor. As streets are the main public space of the city, the research focus groups are all people who live in the city with special focus on pedestrians. The research uses the case study method by selecting four case study areas by using criteria that are: areas located in the core part (CBD) of Addis Ababa, street with width of twenty meter and above, selecting streets with low rise and high rise buildings, and also picking on streets that entertain different functions and activities, and finally picking on areas which are most frequently used. The case areas are found in Merkato, Beherawy and Piazza areas. The research employs primary and secondary data. Data is collected by using randomly distributed survey questioners within the site. In addition to this, data has been collected from different experts and taken as input for the research. The approach or methodology for this research is the case study method based on qualitative and descriptive methods. In this research, the value of vibrant street life is discussed And the current situation of the existing streets with their landscapes and built forms are analysed by using different criteria. It has made sure that built forms and activities within them have their own contribution in creating vibrant street life. In terms of scale, enclosure and proportion the research has identified that almost all of the case areas have a good sense of enclosure because of the scale and proportion of the adjacent buildings. Considering street frontage in terms of activity and comfort some areas are xii found out to be not convenient for their users because of their over crowdedness but some areas are safe and comfortable to their users because they are diverse in activities and existence of arcade buildings and on the other hand in all areas the number of peoples use the street differ in different times of a day. But also the research found out there are dormant buildings which resulted inactive streets on some areas. In analysing the areas in terms of having clear demarcations for pedestrians all of them have demarcation but in a two different ways; one in a level difference the other by building arcades. In addition by seeing their visual attractiveness and cleanness the research has found a balanced result some have good qualities but some are not good in quality people go there just for necessary activity. In Landscape and street furniture we can say that there is Absence of adequate street furniture’s and facilities in all areas basically they do not consider people with disabilities. In terms of being memorable it is been identified that diverse optional activities and unique features has a potential of making places memorable and easy to identify. Therefore, the research has recommended maintaining the existing good qualities of the streets and to create sense of belongingness, liveable and more attractive; the street and adjacent buildings must hold diverse optional activities instead of necessity activities, should have attractive facades and mixed details, Visual connectivity, staggered built edges, proper Setbacks and proportional scale. Similarly streets must have Street furniture with a clear demarcation between pedestrian and vehicles and Provide easy access for people with disabilities. In general in order to see these design considerations it is recommended to create awareness and structural integration with in stakeholders about the benefit of creating vibrant street life

    Creating Safe Sidewalk for Crime Prevention: The Case of Amce area, Addis Ababa
    (Addis Ababauniversity, 2016-09) Becho, Rabira; Wegayehu, _Fisseha (PhD)
    Safety is one of the most critical factors affecting the quality of sidewalk. Sidewalk users reliably recognize their risks from crime to be significantly high, discouraging many from using sidewalk. Study aims to create safe sidewalk to prevent crime the case of AMCE area in Addis Ababa. Its analysis and propose was based on the primary and secondary data of the case study. The secondary data was collected from the concerned agencies and related references. However, primary data has been generated and analyzed with the help of surveys. The findings of the study illustrates that crime has significant correlation with the built environment along sidewalk and sidewalk. Physical design can shape human behavior for the better. Built environment along sidewalk and sidewalk have an impact on fear and crime influence wellbeing, particularly through restrictions on movement. Studies of the result show that the main causes of sidewalk safety problems included: low prospect, high refuge, high roundedness, lack different activities, low rise building height, lack of seating, lack mixed use, dense vegetation, lack of windows and door opening up onto a street. Safety is the basic necessity of urban development. Being able to walk in a safe sidewalk is of high value. Reducing crime and fear of crime can improve the quality of life. Good design of physical environment can reduce opportunities for criminal and develop feelings of safety. Studies show that changes of design of places, sidewalk, buildings and spaces can contribute in reducing crime. This study identify that crime prevention is largely achieved through applying lighting, activity, mixed use, way of finding, high rise building height ,closed circuit television, recreation area, open space and natural surveillance in ways that can reduce crime. The active involvement of community in spaces draws more “eyes on the street,” which in turn to prevent criminals. This paper concluded that good design can make crime more difficult to commute, increase the likelihood of detection of criminal activity and improve safety of sidewalk. The researcher recommends at any planning and design stage, every development has aspects of design that should be considered to reduce opportunities for crime. Urban planner ,Urban designer, Architect and local authority plays a role in shaping physical environment along sidewalk and sidewalk that are safe for people.

    Creating walkable environment for axum city to encourage tourist mobility /the case of axum old settlement
    (Addis Ababauniversity, 2015-06) Gebru, Nigusse; Yoseph, Ezana
    Walkway spaces are an essential element of livable towns and cities in which people want to live. They can contribute in promoting walkable and well-connected areas. In any situation when people are asked as to why they choose to live in a particular location, most people usually say „this is walkable area”. It is natural that People want to live in places where there is a good range of amenities and facilities located within easy reach, such as open space, retail and recreational areas, good schools and childcare facilities, and good transport links to places that they need to access services. In both the developed and developing world, pedestrian friendly city is considered to be a prerequisite for enhancing urban life and play significant role as catalyst for safe and comfortable transport system. Furthermore, it is understood that in order to realize such urban environment urban design must include viable and accessible walkable routes. Realizing this fact this study has tried to assess the situation of the existing walkability of Axum city by selecting a case study area in the old settlement. Based on the existing problems, Axum hardly meets the required urban quality and standard of tourist city in its facilitation of walking space provisions as urban public spaces. Therefore, the purpose of this paper is to develop a set of detailed recommendations and approaches that could enable the tourist-oriented pedestrian system to play a major role in creating safe, sustainable, and equitable mobility in the city to be a touristic heritage site. Using such detailed regulations and guidelines and public stakeholder involvement, a uniform understanding can be reached within the different municipal divisions and walkability quality can be increased both for residents and visitors. The analysis is based on the primary data by using various tools including interview, questionnaire survey, visual survey/observation, focus group discussion and secondary documents that were collected from the concerned agencies, of Axum city. In general the lack of integrated urban walk way infrastructure and lack of common standards, lack of strong link between the land use development and tourism development are some of the findings of this research. Based on these findings the researcher has forwarded detail recommendation that includes designing the walk ways that fit to tourist city context as it is indicated in the detail recommendation and guidelines
