Abstract

Kentler, iklim değişikliğinden en çok etkilenen sistemlerden biridir. Mavi-yeşil altyapı sistemleri sağladığı ekosistem servisleriyle kentlerde iklim değişikliğinden etkilenebilirliğin ve afet riskinin azaltılmasına, dolayısıyla iklim değişikliğine uyum sağlanmasına önemli katkılarda bulunur. Bu nedenle araştırma sorusu, Bayraklı'nın mevcut mavi-yeşil altyapısının 100 yıl tekerrürlü yağışlar karşısında ne kadar etkilidir? şeklinde tanımlanmıştır. Bu kapsamda mavi-yeşil altyapı bileşenleri tanımlanmış, 100 yıl tekerrürlü yağışın gerçekleşmesi durumunda bu alanlarda yüzey akışa geçecek su miktarları hesaplanmıştır. Araştırmada mavi yeşil altyapının ilçenin % 37`sini kapladığı bu alanların birbiriyle bağlantılı bütüncül bir sistem oluşturmadığı belirlenmiştir. 100 yıl tekerrürlü yağışta mavi yeşil altyapı bileşenlerinde 1269857,30 m3 suyun yüzey akısla tutulamadığı belirlenmiştir. Çalışmada, Bayraklı ilçesinin mevcut mavi-yeşil altyapısının olası ekstrem yağışlara karşı yeterli su tutma kapasitesine sahip olmadığı, bu durumun yeşil altyapı bileşenlerinin özelliklerine göre değişiklik gösterdiği görülmüştür. Bulgular doğrultusunda iklim değişikliği ve ekstrem yağış miktarları göz önünde bulundurularak mevcut mavi-yeşil altyapının ve kentin iklim direncinin artırılmasına yönelik uyum önerileri sunulmuştur.

The impact of blue-green infrastructure on climate resilience for hydrometerological hazards: The case of Bayraklı, İzmir

Abstract

Urban areas are one of the most affected systems by climate change. Blue-green infrastructure systems make significant contributions to the reduction of the vulnerability against climate change and disaster risks in urban areas and to adaptation to climate with the ecosystem services they provide. This study aims to determine the blue-green infrastructure (BGI) and its water related disaster mitigation functions in Bayraklı, İzmir. Therefore, the research question is defined as: how effective the existing BGI of Bayraklı is to handle a 100-year frequency storm. In this context, the components of BGI were defined, and their runoff values were calculated by considering a 100-year frequency storm event and by taking the ecological characteristics of these areas, such as vegetation, and surface permeability into account. The findings showed that BGI is inadequate to remove 1.269.857,30 m3 stormwater runoff from the city in the events of a 100–year of rainfall. Potential water retention capacity of BGI varies according to the characteristics of the green infrastructure components. Based on the outcomes of the study, recommendations were presented to increase climate resilience of Bayraklı district by the existing BGI.
