    Kritik Altyapı Olarak Yeşil Altyapının Yönetişimi: İzmir Örneği
    (2025) Ertem, Hazal; Velibeyoğlu, Koray
    Kentsel altyapılar, su, elektrik, sosyal hizmetler ve yeşil altyapı gibi temel hizmetlerin sağlanmasında temel bir rol oynar ve tümü şehirlerin işleyişine katkıda bulunur. Son dönem literatüründe, kritik altyapı (KA) ve yeşil altyapı, doğal ve insan kaynaklı afetler bağlamında önemli konular olarak ortaya çıkmıştır. Özellikle pandemi ve iklim değişikliği dönemlerinde kritik ve yeşil altyapılar giderek daha görünür hale gelmektedir. Ancak, KA'ya ilişkin algı teknik görüşe bağlıdır ve bu da bu tezin ana sorun tanımını oluşturmaktadır. Bu durum, yeşil altyapı da dahil olmak üzere çeşitli sektörlerin KA çerçevesinin dışında kalmasına neden olmaktadır. Bu tezin amacı, kritik altyapıyı ve KA olarak yeşil altyapı planlamasında işbirliğine dayalı yönetişim eylemlerini anlamak için kapsamlı bir çerçeve sunarak tespit edilen boşlukları değerlendirmektir. Çalışma üç aşamalı bir yaklaşım benimsemektedir. İlk olarak, kentsel altyapı çalışmalarında KA ve yeşil altyapının konumu sunulmaktadır. KA'nın kavramsallaştırılmasına ilişkin bir çalışma yürütülmektedir. İkinci olarak, İzmir ve Türkiye'de mekânsal gelişim ve yeşil altyapı için hazırlanan politika belgeleri üzerinde içerik analizi yapılmaktadır. Son olarak, Olivelo Yaşayan Park, Kültürpark ve Atakent Mahalle Parkı planlamasına ilişkin çok sayıda vaka çalışması yürütülerek işbirliğine dayalı yönetişim süreçleri ortaya çıkarılmaktadır. Bu tezde, vaka alanlarının kritik altyapı olarak yeşil altyapı potansiyeli ve işbirliğine dayalı yönetişim sürecinin potansiyeli sunulmaktadır.

    Reading Types of Urban Form as a Tool for Conservation Development Plans
    (Izmir Institute of Technology, 2021) Güçer Payamcı, Evrim; Velibeyoğlu, Koray
    Urbanization processes and incremental approaches ignore, even destroy, the continuity of the built environment that is defined with the historical traces. Planning studies, which aim to provide continuity or create the future with references of the past, require a comprehensive and pro-determinist urban analysis. This study aims to analyze existing city and its communication with former layers to reveal continuity of the city. Such analysis can be defined as reading urban layers, or typological-morphological analysis including social dimensions that create layers. In this context, urban typo-morphological approaches and on conservation development plans is handled. Existing legal framework and Technical Specifications of Conservation Development Plan is evaluated and, conservation development plans prepared through these specifications is criticized as their insufficiency for multi-layered historical cities. An analytical method is presented to read urban texture diachronically and synchronically as an attempt to improve integrated conservation methods. Especially, reading method of Caniggia and Petruccioli, representators of Italian Morphology School provides knowledge to constitute the method. Some parameters are formed in an attempt to understand formation process of multi-layered historical cities.

    Rural-Ecological Commons: Case of Pastures in Izmir
    (Izmir Institute of Technology, 2018) Hazar, Dalya; Velibeyoğlu, Koray
    The main research interest of this study is to determine the conflicts on the pastures, which are defined as the rural-ecological commons that are important for biodiversity and ecological sustainability. The study focuses on the transformative impacts of enclosure and commodification processes on the pastures. Pastures are crucial entities especially within the four dimensions, rich biodiversity of flora and fauna, rural development, erosion prevention, and rural traditions. Case study areas are located at three districts of İzmir are examined within the context of the conflicts on the pastures in relation with the recent legal regulations, determination, delimitation and allocation processes, malpractices, climate change and the civil responses. The data gathered from the snowball interviews, in-depth interviews with professionals and village headmen, personal observations, commission reports and media analysis are evaluated by the content analysis to determine the main conflicts to generate the pasture dimensions for the eDPSIR causal network model. DPSIR is a facilitative organization tool, which aims to understand the cause and effect relationships in the environmental and social issues to eliminate the socio-environmental conflicts and to simplify the data transmission for better communication with the decision-makers, which also has a potential to be used during the EIA and SIA report processes. In this study, a pasture dimension set within an eDPSIR causal analysis model is constituted for re-positioning and re-evaluating pastures in the planning and design literatures, and the verification of the data enhanced by the methodological triangulation. The exploratory case study method is the research design strategy of the study. Outcomes of the study reveals the main land use conflicts on the pastures and the triggering drivers, pressures, states, impacts and the recommended responses. The study confirms that the ecological-sensitive planning can be a crucial tool in terms of protecting and improving the pastures.

    Evaluation of Creative Industry Clusters Through the Ecosystem Approach: Investigation of Weedding Wear Sector in Izmir
    (Izmir Institute of Technology, 2015) Mengi, Onur; Velibeyoğlu, Koray
    The emergence of new economy has brought the creative industries onto the urban research agenda. Despite the extensive literature on the subject, there is need of a more in-depth approach to investigation the unique formations of creative industry clusters. The aim of this dissertation is to explore the particular organizational and spatial structures of creative industry clusters from the ecosystem perspective. This present study recognizes the fashion industry as a creative industry and the wedding wear sector as its subset. Then, it investigates how the cluster of wedding wear sector operates as an ecosystem in terms of the diversity, interaction, competition and evolution in the case of Mimar Kemalettin Fashion District. The methodology consists of the literature review, preliminary field studies, development of the DICE model which explores the diversity, interaction, competition and evolution of ecosystems in a particular space, pilot study for testing the model, data collection via site visits, DICE survey and additional interviews on site, data processing through descriptive analyses and regression analyses, and conclusions. The findings reveal that the existing cluster is young and emerging. This ecosystem currently self-operates with shortage of diversity in a concentrated spatial structure. The role of geographical proximity and the existing local buzz are substantial on excessive internal interactions. The existing competitive atmosphere is portrayed as a win-lose situation and there is a considerable disinterest towards to collaborations. For evolution, the ecosystem mutually co-evolve with mutation occurred inside the firms. Also, the crossover is found primarily a localized phenomenon.

    Institutional Use of Information Technologies in City Planning Agencies: Implications From Turkish Metropolitan Municipalities
    (Izmir Institute of Technology, 2004) Velibeyoğlu, Koray; Süel, Akın
    This study argues the pivotal relationship between the computing technology and its organizational context. It focuses on nature of implementation in organizational settings that are becoming increasingly important. A further motivation point for this study is to reveal the different discourses (managerial/political/emotional etc.) in the cycle of implementation. The assumption behind this interest is that IT and other technologies are not value-neutral and these tools have the possibility of shaping the goals and agenda of the planning profession.As a part of methodology of the thesis, a comprehensive literature survey was completed around the theoretical issues that constitutes the framework of IT/IS adoption in organizations with a particular reference to urban planning and management. The statements and research questions were tested in the planning departments of selected metropolitan municipalities (Ankara, Izmir, and Bursa) that are experiencing information technologies and systems in various implementation stages. The research strategy was based on a variety of qualitative approaches, including two different types of closed questionnaire-based surveys and semi-structured/unstructured interviews. To measure the success/failure degree of the planning technologies used in the case study organizations in the 'user' dimension of the study, DeLone and McLean.s (1992) IS Success Model and Heeks'(1999) ITPOSMO model were used.Case study research revealed the current stands of ICT implementation in urban planning departments of local governments. It was also evaluated planning practitioner.s commitment and dependence towards computerized planning tools in working practice. In a more exploratory context, a progressive research agenda for ICT implementation in public planning agencies was developed based on the implications of empirical research and literature-based analysis.
