Öğe Assessing disaster vulnerability and proposing an adaptive disaster risk reduction framework: the case of Istanbul(Springer, 2025) Haksevenler, Betul Hande Gursoy; Senik, Berfin; Sengul, Zeynep; Akpinar, AydinThe importance of vulnerability analysis in disaster management is increasingly recognized, especially in megacities like Istanbul. This study focuses on conducting an in-depth analysis of the vulnerabilities of Istanbul's districts to various disasters such as earthquakes, landslides, floods, tsunamis, and sea-level rise. The evaluation considered three key factors: exposure, which refers to the shocks and stresses that a district may experience and the frequency and extent of potential losses; sensitivity, which indicates how the district responds to these shocks; and adaptive capacity, which reflects the district's ability to withstand and recover from such impacts. According to these key factors, indicators were identified, relevant data were collected and generated, and the Analytic Hierarchy Process method was applied for weighting. The study reveals that districts located in the southern belt, particularly those with dense urbanization and coastal areas, exhibit higher levels of vulnerability. Among Istanbul's 39 districts, 13 districts, including Gungoren, Bahcelievler, and Zeytinburnu, were classified as highly vulnerable. Additionally, 14 districts were moderately vulnerable, 9 had low vulnerability, and 3, including Silivri, Catalca, and Sile, had very low vulnerability. An adaptive disaster risk reduction framework was proposed for the districts. These findings are intended to assist local governments in more effectively planning disaster management and risk reduction strategies. The findings support Istanbul's resilience and offer valuable guidance for urban planning and disaster management, both locally and globally.Öğe An assessment on size and site selection of emergency assembly points and temporary shelter areas in Duzce(Springer, 2021) Senik, Berfin; Uzun, OsmanOpen green spaces contribute to urban/rural life in terms of ecological, recreational, spatial, economic, etc., functions as well as prevention of natural disasters, mitigation of its impacts, and providing spatial support to people before, during and after a disaster, especially an earthquake. Therefore, during and after the earthquake, there is need of planning of sufficient and safely (suitable site selection) open green spaces, which will provide emergency assembling and temporary and/or long-term shelter of the public, which can be accessed at certain distances, as emergency assembly points and temporary shelter areas (multiple uses). In this study, the suitable size, accessibility standards and site selection criteria, which are discussed separately in the literature, were determined in a way to coincide with the natural and cultural landscape characteristics of Duzce city center. According to these standards and criteria, some determinations have been made in the study area. Firstly, the situation of emergency assembly points and temporary shelter areas in Duzce city, which has two earthquake experiences (in 1999), has been determined with field survey and the data of 1/1000 scaled Implementary Development Plan, which is planned in 2010 and is revised in 2017, and transferred to Geographical Information Systems. Secondly, in the suitability analysis, the criteria that increase/decrease the risk in the neighborhoods were integrated with the data at the first stage and very suitable, suitable and unsuitable areas were determined. Lastly, the size (m(2)per capita) and accessibility (service radius) of the emergency assembly points and temporary shelter areas determined by the Governorship of Duzce Provincial Disaster and Emergency Directorate have been evaluated according to the relevant standards. It has been determined that there are deficiencies in the site selection and size of the emergency assembly points and temporary shelter areas in the city and in this context the mapping of the neighborhoods where the size of the area is insufficient and areas where cannot access emergency assembly points and temporary shelter areas in the whole city has been realized. As a result, some suggestions have been presented in Duzce city center regarding the planning of open green spaces and integration of standards and strategies for natural disasters (earthquake).Öğe Developing a framework for a sustainable city index: A comprehensive approach to urban sustainability(Elsevier, 2025) Haksevenler, Betul Hande Gursoy; Senik, Berfin; Sengul, Zeynep; Sorhun, EnginThis study aims to develop a Sustainable City Index to assess the sustainability performance of cities. In this context, Istanbul, with its 39 districts of diverse characteristics, has been selected as a pilot case. Although the study focuses on districts, the large population of a single Istanbul district and consistent data accessibility enhance the index's relevance at the urban scale. The study integrates environmental, social, economic, and institutional indicators to establish a comprehensive index for evaluating urban sustainability. Additionally, considering the potential impact of different levels of urbanization on sustainability performance, spatial analyses based on population density and land permeability have been conducted, and the applicability of the developed index has been examined for districts with varying degrees of urban development, including both densely built-up centers and urban peripheral areas. Furthermore, potential limitations in data accessibility have been considered, and reliable, representative indicators have been identified to assess whether it is feasible to develop a core Sustainable City Index. The findings indicate that the developed index not only provides meaningful results in measuring the sustainability performance of a city but also remains applicable to spatial contexts with differing urbanization intensities. Moreover, it demonstrates that sustainability performance can be effectively evaluated using a smaller set of representative indicators. This index serves as a valuable tool for policymakers and urban planners in developing context-specific sustainability strategies while also offering a widely applicable methodology.Öğe Evaluating the impact of mega-projects-induced land-cover changes on habitat quality: a case study of Istanbul(Routledge Journals, Taylor & Francis Ltd, 2025) Senik, Berfin; Uzun, OsmanThe rapid urban expansion in mega-cities like Istanbul leads to increased habitat degradation, harming biodiversity. Since 2010, the central government of T & uuml;rkiye has proposed and implemented controversial mega-projects in Istanbul as part of neoliberal urbanisation. This study analyzes the impacts of these projects on habitat quality and land-cover changes, especially forest landscape. Results show increased urbanisation, especially in districts hosting projects like Istanbul Airport (IA), Northern Marmara Motorway (NMM), and Kanal Istanbul (KI), significantly reducing habitat quality. The study highlights the need for ecological evaluation in the spatial planning process to mitigate the environmental effects of these developments.Öğe Integrating Sustainable Development Into Urban Management: A Strategic Green City Index for Cities(Wiley, 2025) Gursoy Haksevenler, Betul Hande; Akpinar, Aydin; Sengul, Zeynep; Senik, Berfin; Orak, Nur Hanife; Sorhun, EnginA growing interest exists in robust tools to evaluate urban environmental performance. This study introduces a Green City Index framework, designed to assess and compare the sustainability of urban districts. Istanbul, with its significant population density and economic influence, serves as the pilot city in T & uuml;rkiye. The study included (i) examining existing city indices, (ii) identifying indicators for environmental quality (EQ), community welfare, and DS, (iii) collecting and producing relevant data, and (iv) establishing the Green City Index using the Analytic Hierarchy Process. The highest-scoring district in Istanbul achieved only 59 out of 100, indicating that no district's environmental performance is sufficiently strong. Even in well-managed districts, EQ was lacking. A significant relationship between the total index and other subcategories was observed. Recognizing index development as dynamic, this Green City Index provides decision-makers with a tool for strategic urban management, helping them assess and improve sustainability efforts in line with long-term goals.Öğe Landscape sensitivity-based scenario analysis using flus model: a case of Asarsuyu watershed(Springer Japan Kk, 2022) Senik, Berfin; Kaya, H. SerdarThe landscape is a dynamic and multidimensional concept which includes natural and/or cultural components, ecosystems, relations and processes. The sustainability of landscapes depends on the harmony of these ecosystems. Particularly, it is important to identify areas where the landscape is sensitive within the basin and to restrict urban growth in these areas. However, the land cover change that occurs in the form of transformation from natural areas to cultural areas undermines the operability of the processes within the landscape. In this study, two different scenarios regarding land cover change have been developed using the FLUS model for Asarsuyu Watershed between the years 2018-2036 and 2036-2054. With these scenarios, the areas where landscape is sensitive are revealed and the urban growth is restricted in areas where landscape sensitivity is very high and high. In this respect, landscape sensitivity studies provide an important tool for guiding urban growth in an ecological framework.Öğe MODERNITY VS. POSTMODERNITY: ASSESSING THE DESIGN QUALITY OF URBAN PARKS BY AHP(Anadolu Univ, 2021) Kutay Karacor, Elif; Uzun Yuksel, Kiymet; Senik, BerfinThe perceptual design quality of physical spaces has been increasingly studied in the literature in recent years. However, the studies in the field of landscape architecture are insufficient about how the design quality of urban parks built in different periods is perceived today. This study aims to compare urban parks that reflect modern and postmodern designs in terms of design quality criteria. In this context, 4 subjective design quality criteria (imageability, legibility, vitality, diversity) were evaluated for Prospect Park and Parc des Buttes-Chaumont modern period parks, and Millennium Park and Parc de la Villette postmodern period parks. Expert opinion was consulted in design criteria and selection of city parks. Analytic Hierarchy Process was used to compare modern and postmodern period parks and Expert Choice software was used. In this study, 4 urban parks were defined as alternatives and 4 design qualities were defined as criteria. The results revealed that the designs of the city parks reflect the postmodern design line that perceived with higher quality. Besides, the most prominent criterion among the design criteria was found as Imageability. This study makes a perceptual contribution to the comparison of the design quality of urban parks of different periods.Öğe A process approach to the open green space system planning(Springer Japan Kk, 2022) Senik, Berfin; Uzun, OsmanOpen green spaces have significant contributions to the city, urban residents and ecosystem. However, these contributions could not be fully reflected on the urban space due to rapid urbanization. Furthermore, studies on this reflection have focused only on a specific function of open green spaces without a holistic approach. Also, there is no common framework for the definition, classification and standardization of open green spaces or a comprehensive analysis of these domains. The present study aimed to propose a guideline that included five criteria to serve as a baseline to plan open green space systems. In the study, open green spaces and the city were considered as a subsystem of the landscape. Thus, open green space objectives and strategies were proposed based on the landscape functions, urban character and urbanization level (urban density). Furthermore, the study reconsidered the definition and classification of open green spaces and recommended standards. These standards were categorized in two groups based on recreational standards and natural disasters. Thus, the open green spaces were analyzed based on qualitative, quantitative, connectivity and location selection criteria with a holistic approach and a multi-dimensional framework was developed based on ecological, recreational and disaster criteria.Öğe The Role of Nation Gardens in the Planning and Design Processes of the Open Green Space System(Kare Publ, 2021) Senik, Berfin; Uzun, OsmanAs is known, open-green spaces are an integral part of urban sustainability. They provide ecological, social, recreational, and spatial contributions to cities, with many different typologies. It is possible to reflect these contributions (multifunctional) to the urban space with a systematic approach. In this context, both in the world and in Turkey, many goals, strategies, and standards regarding opengreen space have been developed/being developed. In recent years, the concept of the nation garden, which has historical importance, has come to the fore as an open-green space typology in Turkey. This concept has also started to be addressed with different opengreen space strategies. Accordingly in this study, the role of nation garden concept in the planning and design processes of the opengreen space system was examined. In this context, the historical development of different open-green space typologies in the world and in Turkey has been emphasized. In the next stage, the legal-administrative structure in Turkey regarding open-green spaces was examined. For this purpose, determinations were made regarding the effect of the Nation Garden Guideline, put forward by the central administration, on the planning and design of the open-green space system. Ultimately, some suggestions were made for the integration of nation gardens with ecological corridors, which were also brought to the agenda by the central administration. Thus, a base that can lead to the integration of the nation garden concept with other open-green spaces and the planning and design process of a competent open-green space system has been put forward.Öğe Spatial Analysis for Smart City Approach: The Case of Besiktas-Etiler Neighborhood(Springer International Publishing Ag, 2022) Çakır, Anıl; Karababa, Enver Murat; Erdemir, Furkan Talha; Senik, Berfin; Karaçor, Elif KutayWhile the rapid and intense urbanization processes taking place at the global level are transforming the urban landscape at the same speed, they have led to new policy searches in the spatial context at the stage of solving the increasing needs/problems. In this context, one of the most important approaches that come to the fore is the smart city. This approach, which offers technological solutions to the increasing urban problems of metropolitan cities, also offers important spatial opportunities for the sustainability of the urban landscape. In this study, the current status and potentials of smart city applications at the neighborhood scale were determined by drawing a methodical framework (analysis-synthesis-suggestion) based on the smart city concept and containing urban landscape planning goals and objectives in the example of Etiler Neighborhood, which is a part of Besiktas district in Istanbul. In the proposal phase, some spatial suggestions were made at the neighborhood scale based on the situations determined in the analysis and synthesis phase. In this direction, smart city targets and strategies that will contribute to future urban landscape planning studies have been determined.Öğe Unraveling landscape connectivity: The impact of mega-projects on Istanbul's Northern Forests and conservation pathways(Elsevier Gmbh, 2025) Senik, Berfin; Uzun, OsmanNatura 2000 and the Emerald Network are crucial for habitat protection across Europe. Istanbul's Northern Forests are a key part of the Pan-European Ecological Network (PEEN). The rapid expansion of large-scale infrastructure projects, such as Istanbul Airport (IA), the Northern Marmara Motorway (NMM), and Kanal Istanbul (KI), in Northern Forests, has severely weakened landscape connectivity and threatened biodiversity in this vital region. This study assesses mega-project impacts on structural and functional connectivity using directional graph analysis from 2000 to 2020, identifying 2010 as a turning point due to the initiation of these projects. Results show a significant decrease in connectivity metrics, such as a 26.8% reduction in structural corridors and substantial decreases in corridor length and node degree, particularly in the NW, N, and W directions identified as high-impact areas. These areas, located near IA, NMM, and KI, exhibit critical losses in ecological corridors and stepping stones. Potential corridors also diminished markedly in length and density, indicating reduced functional connectivity. It was observed that these declines accelerated in 2020 and might accelerate in the 2020-KI periods, especially after the construction of mega-projects started in 2013 and afterward. The study emphasizes the need to reframe landscapes as habitable spaces for ecological sustainability and outlines specific policy recommendations, including the establishment of a legal framework that defines ecological network components and connectivity types, as well as short-, medium-, and long-term ecological restoration strategies. These measures aim to mitigate the impacts of rapid infrastructure development and ensure the long-term protection of Istanbul's Northern Forests within the broader ecological network.
