Article Citation - WoS: 1Citation - Scopus: 1Socio-Economic and Development Disparities Over the Long-Run: Exploring Spatial Heterogeneities in the Case of Turkey(Hungarian Central Statistical Office, 2024) Doğan, Fehmi; Duran, Hasan Engin; Karabakan, Berfin; Dogan, Fehmi; 01. Izmir Institute of Technology; 02.02. Department of Architecture; 02.03. Department of City and Regional Planning; 02. Faculty of ArchitectureThe aim of this paper is to explore the evolution of socioeconomic development and income disparities and convergence patterns across Turkish provinces, emphasizing the impact of spatial heterogeneities. We propose two types of contributions to the literature. First, most of the studies that apply the 13- convergence method presume a unique 13 parameter, assuming that all regions homogenously converge to the steady state at the same pace. However, we argue that relaxing this assumption by way of considering spatial heterogeneities might be more informative. Second, we provide a simple solution to a severe problem: The neoclassical model assumes a monotonic saddle path along which economic fluctuations are not considered, which might be particularly influential with regard to convergence when the time span is too short to capture long-term evolution. Many empirical studies cover only short periods, which may be easily dominated by recessions or expansions, significantly biasing the results. To overcome this problem, we look into two datasets covering long periods (1963-2017 and 1975-2021). Having applied various empirical methods, such as spatial regressions, GWR and nonparametric regressions, we obtain several results. First, at the country level, there is empirical evidence of regional convergence and decreasing development inequalities. Second, however, this convergence process is not valid in all areas. We conclude that there is nonnegligible spatial heterogeneity that should be taken into account in such analyses.Article Citation - Scopus: 1Factors Affecting Tourist Visits To Archaeological Sites in Turkey: a Spatial Regression Analysis(Lodz University Press, 2023) Avcı, Ali Berkay; Duran, Hasan Engin; Duran, H.E.; 01. Izmir Institute of Technology; 02.02. Department of Architecture; 02.03. Department of City and Regional Planning; 02. Faculty of ArchitectureThe study focuses on the factors affecting visitor numbers to archaeological sites in Turkey. The aim is to investigate the geographical, economic, and demographic factors underlying the visits using statistical methods. The study covers 117 archaeological site visits in 2019. Although existing studies analysed determinants of visits to archaeological sites of different countries, the evidence needs to be explicit. Methodologically, the classical linear regression models are primarily applied in the literature, whereas the incorporation of spatial dependence has largely been ignored. This study contributes to the literature by employing demographic, economic, and climatic factors and spatial relations between the sites. Therefore, spatial autoregressive (SAR) and spatial error models (SEM) are developed in the analyses. According to the results, WHL inscription and distance to the city centre are crucial factors for the visits. In addition, the study emphasizes the significant negative effect of spatial dependence on visitor numbers of archaeological sites near each other. © by the author, licensee Łódź University – Łódź University Press, Łódź, Poland.Article Citation - WoS: 6Citation - Scopus: 7Contextualising the Housing Problem of the Roma Community in Relation To Counterurbanisation in Urla, İzmir(Elsevier, 2024) Arslan Avar, Adile; Doğan, Fehmi; Doğan, Fehmi; Avar, Adile; Özcan Cive, Yağmur; Akış, Tonguç; Akış, Tonguç; 02.02. Department of Architecture; 02.03. Department of City and Regional Planning; 02. Faculty of Architecture; 01. Izmir Institute of TechnologyThis paper examines how the housing problem of the Roma people, living already under severe socio-spatial circumstances, has been exacerbated by counterurbanisation over recent decades in the resort town of Urla, İzmir. Based on empirical socio-spatial research adopting methodological pluralism integrating qualitative and quantitative research techniques, the study uses in-depth interviews and secondary data (e.g., real-estate web data, official statistics, and local media) as well as spatial analysis of satellite images. We limited our study to the proximity of the town center of Urla, considering the Roma community's ‘right to the city’, ensuring their right not to be exiled to the spaces of discrimination, and not to be exempted from their right to appear and co-exist in the town center. As Urla became a prominent and attractive destination of counterurbanisation in Turkey, its growth was intensified by high-end housing production. Coming to 2000s, its urban-rural texture remained, at least physically, ‘rural’, but it had undergone significant transformation. And while this recent higher-end development accompanied by counterurbanisation is sanctioned by local authorities, the public and property owners, it leaves no room for the Roma people to find decent housing. An inquiry on the housing problem of the Roma people in Urla in relation to counterurbanisation and accompanying housing production contributes to understanding the dialectics between deregulated housing market, commodification and uneven distribution of treasury lands, neoliberal regulations, and fragmented development plans implemented in highly “path-dependent” ways. © 2023 Elsevier LtdArticle Evaluation of the Effects of Covid-19 Lockdowns and Strict Restrictions on İstanbul's Air Quality(İstanbul Teknik Üniversitesi, 2023) Köse, Şüheda; 01. Izmir Institute of TechnologyThe Covid-19 pandemic, which started in Wuhan, China, led to several strict restrictions and lockdowns in Turkey, like many other countries. Although lockdowns have had a socially and economically negative impact, they have affected the air quality in a positive way. The aim of this study is to examine the spatial impact of lockdowns on air quality in İstanbul and to determine the correlation of polluting indicators. In line with the determined purpose, PM10, SO2, NO2, CO and NOx parameters were spatialized with ordinary kriging method in 5 different time intervals and the relativity levels between meteorology, transportation and particles that cause pollution were examined with the Pearson correlation method. As a result, lockdowns caused an increase on CO and SO2 by up to 28%, while other particles decreased by 2% to 23%. Compared to 2019, a decrease of up to 60% in all particles except CO and SO2 has shown that lockdowns have a positive effect on air quality. It was observed that the pollution, which was concentrated in urban areas before the pandemic, spread to rural areas with the precautions taken. Temperature, number of vehicles and traffic index were found to play an important role in the emission of particles, while wind speed and direction played an important role in the displacement of pollution. It has been observed that finding a positive correlation between pollutants and the factors that trigger pollution has rapidly changed the ecosystem of the city along with the policies affecting air quality. © 2023, Istanbul Teknik Universitesi, Faculty of Architecture.

Department of Industrial Design; 02. Faculty of Architecture; 01. Izmir Institute of TechnologyLebanese filmmaker, actress, and screenwriter Nadine Labaki’s 2011 film Where Do We Go Now? is about the ideological manipulation that gradually results in a big conflict among people in a rural Middle Eastern village where Muslims and Christians live in a peaceful existence. Labaki is known for her politically engaged narratives which refer to the recent political past of Lebanese whilst centralizing strong female figures. Where Do We Go Now? is no exception, and thus, reflects the director's general cinematic style and political attitude. Labaki invites her audience through the comedy to question ideology which interpellates and thus constructs the individual as a subject by revealing the ways ideology creates differences, separation, and conflict among people. In this context, this article strives to analyze the film Where Do We Go Now? employing critical discourse analysis with references to Althusser's conceptualization of ideology and Subject-subject formation. © 2023, University Library System, University of Pittsburgh.

Department of City and Regional Planning; 02. Faculty of Architecture; 01. Izmir Institute of TechnologyGlobally speaking, Asian countries, especially East Asian countries, are facing acute national depopulation situation and severe rural shrinkage development. Based on the continuous surveys of town and village development in Japan, South Korea, and China, this study aims to provide an overview of social policies that have been implemented in the past or more recently in these three countries in response to rural shrinkage, and to outline the core philosophy of these practices to cope with the repercussions. In this paper, we analyze the overall process of rural depopulation and the present features of town and village development in three countries. We subsequently present the social policies over the last few decades and summarize them into four major groups. Furthermore, we highlight that the focus of social policies is not to seek possible ways to reestablish growth but to provide positive support and effective reform to adjust and satisfy the changing needs of towns and villages under the circumstances of shrinking development, including the optimization of public resource allocation, exploring institutional innovation to valorize abandoned assets, and developing endogenous potentials for future sustainable development. Qualitative methods from a combination of literature review, policy review, and field surveys have mainly been adopted in this research. The study of East Asian practices may be instructive for other Asia-Pacific countries, as well as European countries that have been experiencing or will eventually face the challenges of rural shrinkage.Article Citation - WoS: 5Citation - Scopus: 5De-Sealing Reverses Habitat Decay More Than Increasing Groundcover Vegetation(MDPI, 2023) Frary, Anne; Salata, Stefano; Couch, Virginia; Saygın, Nicel; Arslan, Bertan; 02.03. Department of City and Regional Planning; 04.03. Department of Molecular Biology and Genetics; 02.02. Department of Architecture; 04. Faculty of Science; 02. Faculty of Architecture; 01. Izmir Institute of TechnologyModeling ecosystem services is a growing trend in scientific research, and Nature-based Solutions (NbSs) are increasingly used by land-use planners and environmental designers to achieve improved adaptation to climate change and mitigation of the negative effects of climate change. Predictions of ecological benefits of NbSs are needed early in design to support decision making. In this study, we used ecological analysis to predict the benefits of two NbSs applied to a university masterplan and adjusted our preliminary design strategy according to the first modeling results. Our Area of Interest was the IZTECH campus, which is located in a rural area of the eastern Mediterranean region (Izmir/Turkey). A primary design goal was to improve habitat quality by revitalizing soil. Customized analysis of the Baseline Condition and two NbSs scenarios was achieved by using local values obtained from a high-resolution photogrammetric scan of the catchment to produce flow accumulation and habitat quality indexes. Results indicate that anthropogenic features are the primary cause of habitat decay and that decreasing imperviousness reduces habitat decay significantly more than adding vegetation. This study creates a method of supporting sustainability goals by quickly testing alternative NbSs. The main innovation is demonstrating that early approximation of the ecological benefits of NbSs can inform preliminary design strategy. The proposed model may be calibrated to address specific environmental challenges of a given location and test other forms of NbSs.Article Citation - WoS: 1Citation - Scopus: 1State-Level Taylor Rule and Monetary Policy Stress(Instytut Badan Gospodarczych/Institute of Economic Research (Poland), 2023) Duran, Hasan Engin; Duran, Hasan Engin; Gajewski, Pawel; 02.03. Department of City and Regional Planning; 02. Faculty of Architecture; 01. Izmir Institute of TechnologyResearch background: Taylor rule is a widely adopted approach to follow monetary policy and investigate various mechanisms related to or triggered by monetary policy. To date, no in-depth examination of scale, determinants and spillovers of state-level monetary policy stress, stemming from the Federal Reserve Board's (Fed's) policy has been performed. Purpose of the article: This paper aims to investigate the nature of monetary policy stress on US States delivered by the single monetary policy by using a quarterly dataset spanning the years between 1989 and 2017. Methods: We apply a wide array of time series and panel regressions, such as unit root tests, co-integration tests, co-integrating FMOLS and DOLS regressions, and Spatial Panel SAR and SEM models. Findings & value added: When average stress imposed on states is calculated, it is observed that the level of stress is moderate, but the distribution across states is asymmetric. The cross-state determinants behind the average stress show that states with a higher percentage of working-age and highly educated population, as well as those with higher population density and more export-oriented are negatively stressed (i.e. they experience excessively low interest rates), whereas higher unemployment rate contributes to a positive stress (too high interest rates). To the best of our knowledge, the contribution of this paper lies in estimating monetary policy stress at the state level and unveiling some of the determinants of this stress. Moreover, the paper makes the first attempt to empirically test spatial spillovers of the stress, which are indeed found significant and negative.Article Citation - WoS: 12Citation - Scopus: 12Economic Resilience and Regionally Differentiated Cycles: Evidence From a Turning Point Approach in Italy(Wiley, 2023) Duran, Hasan Engin; Duran, Hasan Engin; Fratesi, Ugo; 02.03. Department of City and Regional Planning; 02. Faculty of Architecture; 01. Izmir Institute of TechnologyThe literature on regional resilience often neglects the timing of recessions and simply uses national cycles. Region-specific cycles and turning points might bias the results, however, and affect the choice of regions to target with policies. This paper investigates the geography and determinants of regional resilience with a regional turning point approach, using data for Italy, a country with a well-known and sizeable regional divide. The results show that the timing of regional cycles varies substantially and that the detected resilience determinants are different across the two approaches, implying that the policy levers may be wrongly estimated with national turning points.Article Citation - WoS: 11Citation - Scopus: 11Adapting Cities To Pluvial Flooding: the Case of Izmir (türkiye)(MDPI, 2022) Saygın, Nicel; Couch, Virginia; Uzelli, Taygun; Velibeyoğlu, Koray; Salata, Stefano; Baba, Alper; 02.03.

The quantity, duration and intensity of events, such as flash rains and heat waves, will increase the vulnerability of urban regions while exposing citizens to potentially dangerous conditions. According to the current literature, mainstreaming resilience in urban planning means designing rules that strengthen urban systems’ adaptive and self-regulating functions by reducing their vulnerability. In this work, we aimed to build knowledge for the application of the sponge district concept to Izmir (Türkiye), one of Europe’s most vulnerable areas to pluvial flooding. To do this, we first analyzed the runoff in each urban sub-watershed, then employed a composite index to determine potential areas of intervention for nature-based solutions. Results show that 10% of Izmir’s urban areas are extremely vulnerable to cloudbursts, which means that 40% of the urban population is exposed to this phenomenon. Moreover, the runoff calculation in the sub-watershed demonstrated that the potential flood volume is underestimated, especially in the upslope areas. The results can be used as a template to suggest a stepwise approach to mainstream the resilience of densely-inhabited coastal urban catchments.
