Article Geogenic Determinants of Indoor Radon Exposure in Izmir (West Türkiye)(Pergamon-Elsevier Science Ltd, 2026) Alkan, Turkan; Simsek, Celalettin; Sac, Murat; Uzelli, Taygun; Taskin, NurcihanRadon, a naturally occurring product of uranium decay, is the second leading cause of lung cancer. I(center dot)zmir Province in western T & uuml;rkiye, situated within the Aegean extensional regime, comprises complex fault-bounded basins that favor indoor radon accumulation. This study evaluates the spatial variability and geogenic controls of indoor radon to delineate radon-prone zones with public-health relevance. Indoor radon was measured in 79 dwellings distributed across major lithologies and structural settings; detectors were deployed in basements to capture soil-gas infiltration. Concentrations ranged from 12 to 366.5 Bq/m3 (mean 118 Bq/m3), exceeding the national average of 81 Bq/m3; 32 % of sites surpassed the EPA action level of 148 Bq/m3. Highest values cluster in Bornova, Buca, and Kemalpas, a, coincident with fault-controlled sedimentary basins and permeable units. Spatial mapping highlights the dominant influence of lithology and fault proximity on radon distribution and underscores the limitations of uniform, national-scale mitigation policies. We advocate targeted, geology-aware health policies and urban-planning measures for monitoring and mitigation in geogenically vulnerable districts. These findings contribute to medical geology by providing region-specific evidence of radon risk in one of T & uuml;rkiye's most seismically active metropolitan areas. These outputs provide decision-ready evidence for monitoring, mitigation, and building-code updates in seismically active metropolitan settings.Article The Evolving Role of Urban Designers in Generative AI-Assisted Urban Design: Mini-Block Izmir, Turkey(Routledge, 2025) Özden, P.; Tekerci, E.; Velibeyoǧlu, K.Urban design is undergoing a paradigm shift with the integration of Generative Artificial Intelligence (Gen AI), introducing new modes of collaboration between designers and AI tools and expanding opportunities for data-driven and creative decision-making. However, current AI-based urban design tools remain fragmented and lack integrated workflows, often treating design stages as analysis, generation, and visualization as separate processes rather than as an interactive continuum. The study critically examines the evolving role of urban designers in AI-assisted urban design through a scoping review and a case study of the Mini-Block project in the Alsancak neighbourhood of Izmir, Turkey, focusing on how different AI tools interact and integrate within design workflows. Through a systematic evaluation of AI-driven design tools, the research identifies key limitations in how existing platforms support interoperability, iterative feedback, and collaboration between human designers and generative systems. The findings highlight that while AI enhances data processing, scenario modelling, and spatial optimisation, its full potential depends on designers’ ability to manage tool interaction, interpret algorithmic outputs, and integrate contextual insights into generative design processes. The study proposes a framework for participatory AI tools that embed local knowledge in urban design workflows. It also explores the role of prompt engineering as a means of refining AI outputs to ensure contextually relevant and inclusive urban solutions. Overall, the research highlights the need for AI models that are not only technically robust but also socially and culturally responsive, paving the way for more adaptive, inclusive, and participatory urban design methods. © 2025 The Institute of Urban Sciences.Article Citation - Scopus: 1Spiky Metropolitan Landscapes: an Urbanometric Analysis of Growing Agglomerations(Wiley, 2025) Elburz, Zeynep; Kourtit, Karima; Nijkamp, PeterThe spatial configuration of urban systems has garnered significant interest from various disciplines, including urban planners, economists, and ecologists, due to its interconnectedness with various aspects of sustainable development. Research on urban form suggests a departure from the conventional model of a gradually declining density gradient from the city center, giving way to a "spiky" urban landscape characterized by a heterogeneous polycentric pattern. This study aims to examine the recently emerging spiky structure of an urban agglomeration and its determinants, providing insights into the potential prospects of cities. We adopt a new quantitative modeling approach inspired by spatial econometrics and coined here 'urbanometrics'. By utilizing and testing spatial dependence urbanometric models, we seek to elucidate the factors driving these changes, with a specific focus on pluriform urban sprawl in the Mediterranean region, specifically the Izmir city-region. The findings indicate that since the early 2000s, the Izmir city-region has experienced simultaneous decentralization and the emergence of multiple centers, with sharp differences. Furthermore, the results demonstrate that the expansion of highway infrastructure, population growth, and existing convertible (agricultural or forest) land contribute to urban sprawl and the emergence of a "spiky" urban landscape.Article Citation - WoS: 1GIS-AHP APPROACH FOR A COMPREHENSIVE FRAMEWORK TO DETERMINE THE SUITABLE REGIONS FOR GEOTHERMAL POWER PLANTS IN IZMIR, TURKIYE(Konya Teknik Univ, 2024) Koca, Kemal; Karipoglu, Fatih; Ozturk, Emel ZerayGeothermal energy is gaining more reputation and importance around the world. Correspondingly, suitable location selection is a critical step and has become necessary for the successful installation and operation of geothermal power plants. This study investigated suitability of & Idot;zmir region, located in the Aegean part of T & uuml;rkiye, in terms of geothermal power plants applications by using the combination of Geographical Information System and Analytic Hierarchy Process. Based on the request of power plants, thirteen important criteria were evaluated under three main categories named as physical (C1), environmental (C2) and technical (C3). Moreover, expert's opinions were taken into consideration to calculate the importance of these criteria. Key results showed that & Idot;zmir was suitable for geothermal power plants. The final suitability map layer pointed out that %8.73 (1.037 km2) of total area were determined as highly suitable regions in terms of installation. In addition, the obtained suitability map layer was compared with actual geothermal power plants. Based on the comparison study, power plants in Seferihisar were moderately suitable for geothermal power plants while the location of Bal & ccedil;ova power plant was highly suitable. Regarding the suitability assessment in the present study, the location of Dikili power plants had the least suitability score.Article Citation - Scopus: 2The Uncertain Certainty of a Nightmare: What If Another Destructive Earthquake Strikes Izmir (türkiye)?(Mdpi, 2024) Salata, Stefano; Uzelli, TaygunOn 6 February 2023, near Kahramanmaras in south-central Turkiye, an event underscored the vulnerability of cities to seismic activity, revealing a lack of preparedness for substantial shocks. The contributing factors are manifold, yet fundamentally, the collapse of buildings and infrastructure can be attributed to an underestimated capacity for meticulous settlement planning (location) and the adoption of advanced techniques for resilient construction (structure). Regrettably, as has been investigated by many research works, ordinary urban planning in Turkiye hardly finds ways to integrate the vulnerability analysis for settlement expansion, which includes the full integration of geological characteristics with the analysis of building sensitivity. With this work, we wanted to build a composite risk index based on earthquake vulnerability, hazard amplification map, and exposure. We designed the composite index in Izmir's basin, Turkiye's third most populated city, to answer the question: What if a destructive earthquake strikes this densely settled area? The results illustrates how the coupled integration of digital data on geology with settlements and infrastructure in a Geographic Information System environment can be used to produce risk maps and plan the anthropic system's adaptation carefully. Findings demonstrate the city is highly vulnerable to earthquakes and identify priority areas for planning intervention, relocation, and renovation of buildings.Article Modernity, Hygiene and Display of the Body(Yıldız Teknik Üniversitesi, 2016) Yılmaz, EbruThis article focuses on health museums as a building type introduced to the architectural medium at the beginning of 20th century by modern thinking, the ideal of creating a healthy society as a guarantee of progress and development. Health museums provided representation for concepts of modernity and hygiene in a built environment by being spaces that displayed the human body and exhibits related to diseases, hygiene, and medical developments. A modest building in scale and content, the Izmir Health Exhibition building of the Izmir Fair was analyzed in this study to show how it contributed to 1920s and 1930s modern architecture in Turkey and what were the representational meanings of the messages transmitted. The existence of this building, constructed in 1937 in Izmir, should be understood in the context of health policies from all around the world, social engineering efforts, and the process of modernization. The building is an example of a use of modern architecture, but of a type that is waning in popularity in today's contemporary world. Looking back at this building today helps us understand the rising and declining value of modernity in the discourse of hygiene and its effect on the field of architecture. The contribution of the Izmir Health Exhibition building to early modern Turkish architecture is discussed with reference to similar exhibitions and museums around the world.Article Military Intelligence Deeds in the Reports of Izmir British Consulate General (1878-1914)(Ege Univ, 2011) Aditatar, FundaFrom 1825 up to the late nineteenth century the British Levant Consular Service developed highly parallel with the policy of Britain in the Ottoman Empire. During the protection policy of the Ottoman territory which continued until the 1870s, political and commercial aspects of consular services has been formulated almost an equal level. Instead of protecting the territorial integrity of the Empire after the Berlin Treaty of 1878 turned into a controlled sharing and consuls began press to served heavily political direction. The aim of this paper is to evaluate reports of Izmir British Consulate about military intelligence. The voluminous reports of the consulate related with the military intelligence. This situation occurs in Izmir because of commercial importance and strategic location, and also riots and wars all of these can be explained in the intensive military mobility during the last period of the Empire (1878-1914).Conference Object Detection of Urban Change Using Remote Sensing and Gis: Izmir Case(Taylor and Francis Ltd., 2008) Tarhan, Çiğdem; Arkon, Cemal; Çelik, M.; Gümüştekin, Şevket; Tecim, V.This study is an example of how land use changes could be detected via high resolution remotely sensed data. In order to perform "change detection" IKONOS satellite images, belonging to 2001 and 2004, have been used. An automated Graphical User Interface (GUI) has been created for detection of environment. Different image enhancement techniques and a fuzzy inference system have been combined in the GUI. The detection results are classified according to some basic levels such as 20-50% and 70%. Additionally, four different change detection algorithms have been applied which are pixel-based, object based, feature based. These algorithms have been examined according to change detection levels with different image enhancement techniques. At the end of the study, the results have been compared.Article Citation - WoS: 1Citation - Scopus: 1The Multi-Level Policy Learning of Environmental Policy: Insights From Izmir(Routledge, 2019) Velibeyoğlu, Koray; Mengi, OnurA European Union (EU) membership perspective is important for Turkey's harmonization with EU standards, which could have positive outcomes especially in the area of smart environmental management. However, as recent political developments suggest, Turkey is losing hope of full EU membership, and is searching for alternatives, such as privileged partnership. Active contributions of city-level good practices are urgently needed. Policy learning is a part of this process, and an emergent result of ever-changing negotiations involving a multiplicity of actors at the multi-level perspective (MLP). The present study investigates the glocal environmental policy of Izmir, via a review of recent governmental environmentally sensitive local innovative practices. The findings reveal that innovative environments that increase learning-by-doing and learning-by-using will become critical for environmental policy learning in Izmir and perhaps beyond.Conference Object Citation - WoS: 35Detection of Flood Hazard in Urban Areas Using Gis: Izmir Case(Elsevier, 2016) Özkan, Sevim Pelin; Tarhan, ÇiğdemThe aim of this study is to predict the potential flood-hazard areas using Shuttle Radar Topography Mission-Digital Elevation Model (SRTM-DEM). The study area is the province of Izmir. SRTM-DEM of the Izmir Province has 90 m of grid size resolution; 45 m of horizontal accuracy; and 15 m of vertical accuracy. Within this study, obtaining spatial information on flood hazard by using Izmir digital terrain models and by 3D analysis that will help to achieve the regional flood hazard management scheme is aimed. Flood-hazard areas have been identified by the use of digital elevation model covering the study area. The main rivers in the study area are Gediz, Kucuk Menderes and Bakircay that creates the coastal flood plains. In order to estimate the spatial distribution of flood-hazard areas in Izmir, five factors are used: flow accumulation, land use, slope, rainfall intensity, and elevation. The classic hydrological modelling approach was applied to determine the rainfall intensity; rainfall intensity of study region is created with the average amount of total rainfall intensity of fifteen stations in the two basins per minute using the interpolation method (spline interpolation). By the digitizing rivers, topography, flow direction and flow accumulation, as well as the flood detention areas are determined. These factors were combined with the weighted overlay method to determine categorized flood-hazard areas. As a result, possible flood-hazard areas have been determined in the case of Izmir Province.
