    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, Aydin
    The 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.

    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, Engin
    A 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.
