    Climate change vulnerability assessment of Karşıyaka, İzmir
    (Springer, 2024) Canguzel, Aybuke; Hepcan, Cigdem Coskun
    Cities are among the systems with the highest vulnerability to climate change impacts. These impacts greatly affect the population and physical infrastructure of the cities. Vulnerability assessment plays a significant role in identifying vulnerable areas to climate change in the city and developing adaptation solutions for these areas. This study aimed to determine and map the vulnerability level of Kar & scedil;& imath;yaka, & Idot;zmir on watershed scale to climate change hazards, high temperature, flood and sea level rise by using indicator based approach. In this context an indicator set was developed for each vulnerability component, exposure, sensitivity and adaptive capacity, taking into account socio-economic, physical and ecological characteristics of the watershed, and then vulnerability was determined by calculations at the neighborhood scale. The results showed that urban areas in the inland had high exposure and sensitivity to. heat related hazards while coastal areas had high exposure and sensitivity to water related climate hazards. Almost two thirds of the residents lived under the risk of urban floods and extreme heat. The findings also indicated that sensitivity is lower on the inner parts of the study region where population density is low. Furthermore, coastal areas had the highest vulnerability even though they had high adaptive capacity. The findings are expected to be a useful tool for decision makers in increasing climate resilience and adaptive capacity.

    Heat exposure of older people in İzmir
    (Alexandru Ioan Cuza Univ Press, Alexandru Ioan Cuza Univ Iasi, 2024) Hepcan, cigdem Coskun; Canguzel, Aybuke; Yuksel, Ahsen Tugce; Ioja, Ioan Cristian; Hepcan, Serif; Breuste, Jurgen
    The climate crisis poses significant challenges, with vulnerable populations, particularly older adults, disproportionately affected by heat-related health risks. This study evaluates heat exposure among individuals aged 65 and older in & Idot;zmir's (T & uuml;rkiye) coastal districts by integrating land surface temperature (LST) data and demographic census records. Findings reveal that 9% of older adults experience extremely high heat exposure, while 61% face high exposure. Vulnerability is more pronounced in & Idot;zmir's northern and eastern districts compared to southern areas. These results highlight the urgent need for targeted interventions to mitigate heat exposure and protect vulnerable populations.

    Storm Surge Threats: Assessing İzmir's Transportation Network Vulnerabilities
    (Cluj Univ Press, 2025) Hepcan, Cigdem Coskun; Yuksel, Ahsen Tugce; Canguzel, Aybuke; Hepcan, Serif; Ioja, Ioan Cristian; Breuste, Jurgen
    Coastal cities are increasingly vulnerable to climate-related hazards-storm surges, sea-level rise, and extreme weather-which threaten transportation systems. Recent disasters highlight the urgent need for resilience planning. This study evaluates the vulnerability of & Idot;zmir's transportation network under three storm surge scenarios by integrating high-resolution spatial data, IPCC (Intergovernmental Panel on Climate Change) projections, and historical flood records. The analysis applies an indicator-based approach grounded in the IPCC framework, evaluating vulnerability as a function of exposure, sensitivity, and adaptive capacity. Findings show water intrusion ranging from 330 to 12,000 meters across & Idot;zmir Bay, significantly impacting critical infrastructure. Tram lines and ferry piers are most affected, with over 84% and 97% of assets classified as highly or very highly vulnerable. Metro stations (52%) and segments of the & Idot;ZBAN rail system (34%) are also at risk, particularly in low-lying coastal zones. These disruptions threaten urban mobility, economic stability, and emergency response. The current research provides a spatially explicit vulnerability assessment of & Idot;zmir's transport infrastructure under different storm surge scenarios, identifying the most at-risk assets and locations. By applying an indicator-based framework, it quantifies vulnerability in a systematic way and highlights the urgency of targeted adaptation in central districts like Konak and Kar & scedil;& imath;yaka. The findings offer actionable insights for urban planners and policymakers, emphasizing the need to integrate Nature-based Solutions and engineered protections in areas with low elevation and critical transport functions. The methodological approach can also be adapted to support resilience planning in other coastal cities facing similar climate threats.
