Evaluation Of Vulnerability On Turkish Coastal Provinces With Gis

disorganized urbanization and the potential earthquake risk in many coastal
cities threaten the sustainability of coastal cities (Reguero- Griggs, 2022: 996;
www.ipcc.ch, Accessed: 15.05.2022).
Türkiye, which has a coast to the Aegean Sea, Marmara Sea, and Black
Sea, with a coastal length of 8333, has 28 coastal cities, and approximately
45% of the population live in coastal cities (Figure 1). It is estimated that the
effects of climate change and anthropogenic activities on coastal cities will
lead to not only environmental and ecological threats, but also bring about
other serious threats such as food crisis, social inequality, health issues and
economic losses. This requires the discussion of economic and social incidents
while determining vulnerability (www.cip. tuik. gov.tr Accessed: 15.05.2022;
Yalçınkaya, 2021: 924-950).

4. Findings

Physical, spatial, economic and social indicators are assigned points
based on their effect levels. Their effect rates are as follows: physical 45%,
spatial 15%, economic 11%, social 29%. According to the vulnerability study
implemented through Weighted overlay analysis, all the Mediterranean
coastal cities are highly vulnerable. The reasons include the rise in sea levels in
all seas along the coasts of Türkiye. In the Mediterranean Sea alone, in the last
20 years, there has been a 6-cm increase in sea levels. Other reasons include
