    (EiABC, 2017-09) Hunegnaw, Diress; Maru, Mulugeta
    Green infrastructures are defined as parts of urban area with a mix of street side and median trees, neighbourhood parks, sport fields, cultivated land, porous and pervious surfaces, wetlands, lakes, and streams etc that are interconnected. Thus this paper is aimed at assessing green infrastructures and their planning processes of Condominium housing projects in Addis Ababa formulating objectives to answer questions of green infrastructure typologies, land cover proportion, implementation and management strategies. The study used both qualitative and quantitative methods by administering questionnaire, interview and field observation as data collection tools using purposive and random sampling techniques. In purposive sampling; twelve professionals, six officials and six condominium associations who directly involved in the plan preparation, implementation and/or management of green infrastructures were selected while forty seven households who are living in the three selected sites such as Gerji(1), Gellan(1) and Lideta sites were selected randomly . Based on the findings and discussion it is understood that the green infrastructures which were proposed in the neighbourhood design did not define typologies but simply give general terms like green and open spaces. However, the open spaces proposed in the neighbourhood design have already existed in the sites though the management and development of such spaces are poor. Therefore, to solve the problems which has been found in the discussion; the green infrastructure typologies and their land cover proportion, implementation and management strategies should be clarified during the proposal phase and there must be coordination among stake holders taking their mandate and responsibility to implement, develop and manage green infrastructures to make the neighbourhood suitable and safe for living and working.

    Assessment on the perceived needs of condominium residents on the functional uses and values of neighborhood open spaces: the cases of Jemo one condominium site, Addis Ababa.
    (Addis Ababauniversity, 2016-02) Getnet, Eyerusalem; Maru, Mulugeta
    Open spaces in the neighborhood are vital aspects of urban planning and design in environmental and social dimension of living condition. In the planning and designing process of open space, identifying the community’s interest towards the open space is important to determine the functional use and value of the space to meet the society’s need. This research investigates the functional use and values of neighborhood open space and perceptions of condominium communities so as to evaluate the effectiveness of the provided open space among the neighborhood. The study focus on gathering the community perceived needs towards open space and how they would prefer it to be by taking Jemo I condominium residential site as a case study. The case study is selected because most of the residents are relocated to this condominium site from deteriorate slum settlement and residents who use a rental house from all over the country which create the social diversification in terms of age, income status, and living background. Due to this the site is selected to carryon this study. To go through this study, a descriptive methodology is followed. Representative households were selected using simple random sampling to participate on structured questionnaire for this paper. Out of the total buildings clustered with open space 10% of the buildings are selected and among those 20% of one bed room, two bed room and three bed room households are selected. Inputs data for this study were collected using interview, questionnaire and site survey techniques to gather information about the functional use of the open space, community’s common perception of the space, accessibility and adequacy of the space and the space supporting the social affairs. Base on the findings and discussions it is understood that the space usage is dominated by household work related actives which weakness significance of the open spaces for interaction and recreation, Poor management of open space for the enhancement, activities overlapping to each other, Community perception towards open space influenced by the current limited function of the open space and Difficulties of implementing planned open space and integrating landscape design to the neighborhood plan. Therefore, the recommendations in addition with the design typology proposed address the issues that reflect the perception of condominium community in Jemo I Addis Ababa.

    Challenges and Opportunities of Urban Green Infrastructures in Inner Sub Cities of Addis Ababa: the case of Lideta and Kirkos Sub Cities
    (EiABC, 2017-09) Kefale, Alemaw; Maru, Mulugeta
    Urban green infrastructures are essential elements of cities and contribute to the quality of life in numerous ways by maintaining and regulating the environment. However, increased urbanization and development have placed urban green infrastructures under extreme pressure, while unplanned urban growth has resulted in the loss of urban landscape and ecosystems. Among the Urban green infrastructures in Addis Ababa such as Street sides and medians trees, permeable pavements, recreational parks, and river banks have challenges in inner city Areas. This study has assessed Challenges and opportunities of urban green infrastructures in Inner sub Cities of Addis Ababa: the case of Lideta and Kirkos Sub Cities; specifically assessed urban green infrastructures and challenges of recreational parks, Street sides and medians trees, and Cobblestone roads of the study area. Thus, the study used both qualitative and quantitative approaches with case study methodology where questionnaires (majorly close ended), structured open ended interviews, and observation were used as data collection methods and the analysis was done by using SPSS and Arc GIS. The sampling techniques used to do this research were purposive sampling for selection of study cases, nonprobability convenient sampling for collection of data from park users, and Stratified random sampling to collect data about Cobblestone roads. Different challenges of recreational parks were identified such as social, economic, management, technical, physical, and environmental. Furthermore the study has revealed physical, management, technical, and environmental challenges are the challenges of street sides and medians trees, and cobblestone roads in the study areas. On the other hand the study has identified opportunities of UGIs such as UGI proclamations, standards, strategies, policies, and principles among others. Based on the findings of the study it is concluded that urban green infrastructures, in Inner sub Cities of Addis Ababa, faced different challenges including social, physical, economic, environmental, technical and management challenges. Therefore, recommendations are forwarded to address these challenges and bring Sustainable UGI development and management.

    Transforming Slum settlements on Environmentally Sensitive areas to Sustainable Neighbourhood Based on Adaptive Strategies: the Case of ‘Korea-sefer’, Addis Ababa
    (Addis Ababauniversity, 2012-06) Maru, Mulugeta; workneh, Abraham
    Developing countries, including Ethiopia, have implemented adaptive and proactive approaches to deal with the situation in urban slums. The efforts so far carried out in Ethiopia, Addis Ababa in particular to this end includes: upgrading, urban renewal, and eco-city planning among others. The primary focus of these efforts was only on undertaking physical improvements with minor concerns on the socio- economic and environmental dimensions of sustainable development. This paper, therefore, examines the challenges of sustainable development and identifies the views of the people on their future transformation of ‘Korea-sefer’, purposively selected slum settlement in Addis Ababa situated on steep slope and along river bank. The paper also forwarded recommendations and design proposals to curb sustainability problems in the study area Hence, sample size representative of 10% is taken where systematic random sampling method is applied to select households located on three different geographic stratas: river flood zones, slopes greater and less than 15%. The method for randomising is snowballing to select one household from the list of the first 10 household numbers and the rest are systematically selected. The paper further applied structured questionnaires, interviews and field observation to collect primary and secondary data. The data collected were analysed and presented with the help of different softwares, graphs, and tables. Maps were also used to describe the events in the site. Based on the findings of the paper it is concluded that lack of appropriate training, the narrow access roads, overcrowded houses, deteriorated drainage lines, the unintervened steep slopes have aggravated the un-sustainability of the site in economic and physical aspects. Furthermore, the social and environmental un-sustainability is related to absence of open spaces, amenities. It is further aggravated by the presence of wastes on the streets, drainage lines, and river banks coupled with the poor condition of the toilets. In addition to these flooding and dependency on non renewable energy sources have contributed a lot on the un-sustainability of the site. Therefore, the design proposals together with the recommendations forwarded address these issues to transform the slum settlement to a more liveable neighbourhood.
