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.

However, some people do not use the nearest parks, but those with other socio- spatial attributes that make them feel more “familiar”. This study argues that with their facilities, amenities and design, and the surrounding land uses, neighborhood parks do not only accommodate, but also define, regulate, and originate social relations among users. Thus, the design and planning of urban public spaces play a role in the emergence and maintenance of supportive and conflictual relations that lead to familiarity. The study answers two research questions: How do the park attributes shape and mediate the interpersonal relations among the park users? How do gender differences influence the parochial realms in parks? Data was collected through field observations and in-depth interviews with 33 female users of two neighborhood parks in a populous district of Izmir (Turkey). Results state that women’s park visits were related to their gendered roles and responsibilities. Yet their responses point to challenges emerging from physical and social attributes of parks and park surroundings which lead to negotiations to protect their individual or group’s privacy (parochial realm) in neighborhood parks. Mainly, perceived threats to women’s parochial realm are men unaccompanied by child(ren), and exposure to the male gaze. The study highlights the importance of investigating these attributes of neighborhood parks for developing research and public policies to improve women’s presence and perceived safety in public settings.Article Citation - Scopus: 3Creating Spaces for Art: Long Term Impacts of Street Art in the Urban Context(İstanbul Teknik Üniversitesi, 2022) Kolçak, Emre; Kaya Erol, NursenStreet art can be defined as any informal artistic performances or artworks practiced in the public spaces. Street art has the potential to transform the public spaces by contributing to or reducing the quality of these spaces. Through street art, in many cases, public spaces are transformed into places for entertainment, cultural activities, or areas of protests and expression of the feelings and ideas. The impacts of street art practices might be limited to one part of an open space or spread to a district or even to the entire city depending on its temporal dimen-sion. This article aims to examine the relationship of street art and public space. In this context, the article overviews the concept of street art and demonstrates its positive, negative and temporal impacts on public space. This study uses a case study approach and evaluates the long term impacts of street art practices based on the analysis of three cases in the city of İzmir, Turkey. In İzmir cases it is found out that the street art practices transformed the public space in terms of uses, activities and built environment quality and had impacts on economic and social structure of the community. The findings of this study reveal that street art holds the potential of contributing to the city life through creating spaces for artistic activities and moreover of changing the meaning and identity of the public spaces and the settlements.Article Citation - Scopus: 1Evaluation of the Location Choice of Software Industry in Istanbul Based on the Types of Economy(İstanbul Teknik Üniversitesi, 2022) Köse, Şüheda; Berkoz, Ayşe LaleOne of the main fields of economic growth in developing countries is the software industry, which is one of the innovative industries. Istanbul has a great potential for software creation with its artistic potential, its unique cultural heritage, social networks, and engagement. The purpose of this article is to explore the clustering pattern of Istanbul’s software industry and the choice of location from a spatial perspective, based on the types of economy. Three important conclusions have been reached by studying the spatial activity trends of the industry. Results include: (i) the software industry has a polycentric cluster pattern in the historical city center axis, (ii) a seat for the technological parks of particularly prestigious Universities in the center, and (iii) a chosen location in the center of town to benefit from the artistic industry. The results of this study will be a guide to the potential that will lead to the creative economy’s growth in Istanbul’s future plans.Article Urban Protection And Renewal Dilemma: İzmir Mezarlıkbaşı(İstanbul Teknik Üniversitesi, 2021) Akpınar, Figen; Turan, Mine; Toköz, Özge DenizAt the beginning of the 21st century, efforts to preserve cultural heritage in historical settlements is a highly problematic and multi-faceted issue in Turkey. Al-though conservation legislation dates back to 60 years ago, heritage conservation has not been internalized and accepted in the wider part of society, and, has not established a sound political foundation. On the other, however, there is also a lack of integrated land-use planning and management. The purpose of this study is to present the difficulties of dealing with the conservation, renewal, and regeneration for heritage areas in the historic core of İzmir, Mezarlıkbaşı-Kemeraltı, as well as to discuss the intrinsic physical qualities, dynamic characters and diversity of community groups with a view of new spatial agenda. The objective of the study is therefore twofold: 1) documentation of the physical characteristics and values for understanding the place; 2) to evaluate incorporating integrated strategic planning and management approach pointing the need for incorporating, leadership, partnership, integration and inclusion as a policy guideline for the safeguarding the heritage area. Our findings show that the Municipality of İzmir has made a significant attempt as TARKEM’s leadership position, which has succeeded in attracting national and international interest in Kemeraltı and creating opportunities for the future, but partnership (operation), management (structure) and inclusion (its processes) still lack. Community groups are not seen as part of the planning activities and planning has been remote, fragmented and exclusively missing an integrated planning management approach. © 2021, Istanbul Teknik Universitesi, Faculty of Architecture.

Since the aviation industry facilitates a worldwide transportation network for business and tourism, it is considered to be a critical factor for economic growth. This study aims to analyze the relationship between air transport and regional development in Turkey, by using air passenger volume and regional employment data by means of both non-spatial and spatial regression methods. We run a Two-Stage Least Squares (2SLS) regression model with instruments to capture endogeneity, and Generalized Spatial Two-Stage Least Squares (GS2SLS) models to control for the spatial context by using data from 81 Turkish NUTS 3 regions (provinces) between 2008 and 2017. We extend the existing literature by measuring spatial spillover effects of air transport on regional growth. To the best of the authors' knowledge, this study is the first attempt to examine this link by considering both spatial effects and endogeneity problems. The results confirm our hypothesis that air transportation is an important determinant of regional employment in Turkish regions while the impact of air transport on regional employment decreases when spatial effects are taken into consideration.Article Kırsal-ekolojik Müştereklerimiz: Mera Alanları(2018) Hazar, Dalya; Velibeyoğlu, KorayAraştırma, biyoçeşitlilik ve ekolojik sürdürülebilirlik açısından önemli olan kırsal-ekolojik müştereklerimiz olarak tariflediğimiz mera alanları üzerindeki çatışmalara ve mera alanları üzerindeki çitleme hareketlerinin dönüştürücü etkilerine odaklanmaktadır. Mera alanları, yüksek karbon bağlama kapasitesi, zengin biyoçeşitlilik, erozyonu önleme, kırsal kalkınma ve kırsal gelenek açılarından önemli varlıklardır. Araştırma tasarımı yöntemi keşifçi vaka çalışmasıdır. Uzmanlarla yapılan kartopu mülakatlar, muhtarlarla yapılan derinlemesine mülakatlar, gözlemler ve medya analizinden edinilen veriler, içerik analiziyle değerlendirilmiş ve bir mera boyut seti oluşturulmuştur. Araştırma sonucunda, mera alanları üzerindeki çatışmalarına sebep olduğu belirlenen faktörler, baskılar, durum ve etkiler, eDPSIR nedensel ağ modeline uyarlanmıştır. Ekolojik duyarlı planlama, otlatma yönetimi ve faktör-baskı temelli yanıtlar ile iyileştirilmiş kırsal politikalar, kırsal müştereklerin korunması açısından önemlidir.Article Citation - WoS: 3Citation - Scopus: 3The Changing Nature of the Neighborhood and Neighborliness: Urban Spaces of Interaction and Sense of Community, a Case Study of İzmir, Turkey(Locke Science Publishing Company, Inc., 2016) Can, IşınThis research, derived from a pragmatic approach, concentrates on the problem of segregated urban space and the disconnection between buildings and the street. In Turkey, development plans and policies often neglect the organization of space between indoor and outdoor areas. However, previous research has shown that the organization of space between buildings has an important impact on social interaction. Although modern housing estates, with their lack of in between spaces (i.e., spaces that are neither completely private nor public) compared with traditional and mixed-use neighborhoods, support introverted lifestyles, the results of this empirical analysis refuted the hypothesis that modern housing estates would exhibit a reduced sense of community. The outcomes of this study support the arguments developed by urban sociologists and environmental psychologists who claim that physical space may provide for social interactions but not necessarily for a sense of community.Article Citation - WoS: 4Citation - Scopus: 3Sustainable Management of Rural-Ecological Commons: Recommendations on Edpsir Causal Networks(Scibulcom Ltd., 2019) Hazar, Dalya; Velibeyoğlu, KorayThis study aims to reveal the importance of the pastures as the rural-ecological commons in terms of biodiversity and ecological sustainability by focusing on the transformative impacts of the enclosure and commodification processes. Pastures are crucial especially within four dimensions: (1) rich biodiversity of flora and fauna; (2) rural development; (3) erosion prevention; and (4) rural tradition. Conflicts on the pastures and their triggering mechanisms are the main research interests of the study. Sustainable management of the rural-ecological commons has a potential to prevent the conflicts on the pastures. Three case study districts in Izmir (Turkey) are chosen to determine the conflicts on the pastures in relation with the recent legal regulations, determination, delimitation and allocation processes, malpractices and the civil responses. Data gathered from the interviews with professionals and village headmen, literature review, media analysis, and personal observations are evaluated by the content analysis to determine the main conflicts and the pasture dimensions for the eDPSIR (Driving force, Pressure, State, Impact, Response) model, which is an enhanced organisation tool to understand the multi-level relationships in environmental and social issues. The developed pasture dimension set evaluates the rural-ecological commons in relation with the actor relations and geographical aspects during the decision-making, common management and the planning processes.
