    Assessment of green infrastructures and their planning process: the case of condominium housing projects in Addis Ababa.
    (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.

    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 livable neighborhood.
