    Analysis of the Interaction Between Theory and Practice in Urban Planning: Understanding Izmir Experience
    (Izmir Institute of Technology, 2002) Kaya, Nursen; Özdemir, Semahat; Kaya Erol, Nursen; Özdemir, Semahat
    Urban planning, as one of the factors in shaping the urban structure, aims to help to increase the quality of life both through making the necessary spatial arrangements and through development of the urban policies. However the interventions brought through this field of study and action have always been under discussion in terms of the or success of this intervention. Accordingly one of the most ongoing discussions in planning literature covers the issues related to the theory and practice interaction with the aim to see the accordance or disaccordance between planned action and the real world of action and to help to clarify the need or success of this intervention. This thesis study is carried out with the aim to understand the interaction between theory and practice in urban planning. It aims to analyze whether the theory of planning guides to the practice of planning and whether the practice of planning shapes the urban structure. In other words it attempts to clarify the role of theory on practice of planning and the impacts of planning practice on urban structure. This study is formed of two main parts as the theoretical frame and the case study. In the first part the study presented the framework of planning theory and a short review of major theoretical approaches stated in planning literature. In the second part the study presented planning experiences of the city of İzmir through carrying out an analysis of planning practices in terms of theoretical background and implementation of planning decisions. The research method followed for carrying out of the study is mainly based on literature search, İzmir Metropolitan Municipality archives search, Yeni Asır newspaper search and on-site observations. This study found out that planning practices of İzmir had been generally guided by various theoretical approaches and these practices had performed many impacts on urban structure of İzmir. However it can not be claimed that the practice had been successfully guided by the theory or the practice had been successful to shape urban structure. Keywords: Planning Theory, Planning Practice, Theoretical Approaches, Planning in Turkey, Planning in İzmir, Urban Structure of İzmir, Prost, Danger, Le Corbusier, Aru, Bodmer.

    Developing a Strategic Decision- Making Process for Local Energy Planning and Urban Land- Use Evaluations: the Case for Balc¸ova Geothermal Energy
    (Izmir Institute of Technology, 2009) Kutluca, Ahmet Kıvanç; Özdemir, Semahat
    The concept of 'renewable energy' for countries such as Turkey which are classified as poor, in terms of reserving the mentioned fossil energies could be an opportunity for being independent. 'Geothermal Energy' among the renewable energy sources in our country is known as an important type of valid and potential energy sources. Design and land-use are closely linked to the energy efficiency levels for an urban area. The current urban planning practice does not involve an effective landuse-energy evaluation in its 'blueprint' urban plans.The case of Balçova, a district in the Izmir Metropolitan area, is used conformingly for evaluating the proposed master plan and the 'geothermal energy district heating system' use for the concern district.The examination of the existing development plan with an .energy sensitive.point of view, determination of the questioning criteria's, and the evaluation of alternative compromises that can be done on planning principles, form the originality of thesis. The construction is completed by the integration of these policy-planproject scaled approaches during this evaluation.According to the thesis main idea, the proposed energy sensitive land-use planning method can be an effective tool for planners as simulation media in GIS programs using, to evaluate efficiency levels for different plan proposals, letting to know how much energy saving causes how much deviation from the other planning ideals.In the extent of the thesis, an alternative energy sensitive (integrated) land-use planning approach is aimed in the example of 'geothermal energy district heating system' by using development tools of land-use planning, planning brief and plans on .the increase in energy efficiency in urban settlement. approach.

    The Effects of Improvement Plans on Urban Transformation Process in Illegal Built Up/Squatter Areas in Turkey: İzmir and Ankara Cases
    (Izmir Institute of Technology, 2008) Eğercioğlu, Yakup; Özdemir, Semahat
    Today, urbanization problems which have been experienced in the past fifty years in our country have also brought about other deep-rooted problems in other sectors. The migration which started in the 1950s is the major cause of all urban problems. The social and economic problems that arose after migration, later manifested themselves in the physical space; and after the emergence of the first squatter houses a process that later turned into a practice of continuous illegal building construction was to begin. Urban problems have turned into an impasse due to the uncontrolled development and cities spreading hastily towards their peripheries, the changing social structure of cities after migratory waves, continuously mounting spatial problems, lack of policies, an even policies promoting these developments. However, it is stressed by the State Statistics Institute that the speed of population increase will go down significantly in next decades. The decrease in population rate and the focusing of government policies on the transformation of squatter areas give hints for the fact that urban transformation will always be on the agenda in the following years.In this sense, within the scope of this thesis study, especially the transformation processes which formed in the squatter/illegally constructed areas of the post 1980s in Turkey were investigated in detail. In order to present an objective picture of the transformation processes in those areas, two different samples which experienced the same transformation process in the post 1980 period were selected because different transformation processes emerged in different squatter areas where the same improvement plan was applied. Along with this, as two different work areas, the improvement plans which were applied in the squatter/illegally constructed areas in Ankara-Çankaya and Izmir-Konak municipalities were investigated, and the transformation processes were analyzed and the two different processes were reflected. At the basis of this study lies the need for investigating the urban transformation processes in squatter and illegally constructed areas, which seems especially to be a problem of big towns and metropolitan cities, and also the thought of identifying the problem objectively. This study aims at identifying urban renewal form and how the transformation process has developed, and under what sort of conditions within the present settlement of the Turkish cities, in other words in squatter or illegallyconstructed areas in recent years. In this study, in order to find out under what conditions and in which organizational structure market-based urban transformation processes were realized by individuals and in the leadership of constructors, the squatter/illegally constructed areas in Ankara-Çankaya and İzmir-Konak municipalities, where improvement plans were applied, were comparatively investigated. Key Words: Urban Transformation Processes, Squatter Areas, Improvement Plans, Redevelopment, Holistic Planning, Partnerships, Participations.

    Resettlement of Immigrants and Planning in Izmir During the Hamidian Period
    (Izmir Institute of Technology, 2006) Kiper, Nilgün; Özdemir, Semahat
    This study concentrates on the immigration into Anatolia from the Balkans, Caucasian and Crete to Izmir and the resettlement policies geared toward immigrants' establishment in the new land during the Hamidian Period. The aim of study is to investigate the efficiency of planning in term of the application of resettlement decisions that had been structured by the population policies. The other aim is determining the importance of the planning for immigrant's settlements in the late Ottoman planning practice. The planning concept is evaluated in the urban, regional and countrywide scale rather than referring to the physical organisation of the urban space. This study intends, by way of analysing the construction process of the immigrant districts, to reveal the characteristics of the construction and resettlement activities and how the central and local dynamics to realise them, rather than the physical arrangement of the districts. The role of the local administration, the special commissions for charity, local press and local residents has been investigated along with the resettlement process in the city of İzmir and the vilayet of Aydın. The significance of philanthropic activities is revealed in the construction and resettlement process.The official documents, the maps of İzmir and Western Anatolia in the late nineteenth and early twentieth centuries will be investigated along with the news reporting in the İzmir region geared towards the settlement of immigrants.
