Studies Show Istanbul Coastal Systems Face Rising Climate Risk
A comprehensive climate risk assessment by the Istanbul University Institute of Marine Sciences and Management reveals that Istanbul's coastal infrastructure faces escalating threats from rising sea levels through 2300. Leveraging IPCC-aligned models, the study identifies Istanbul as highly vulnerable due to its dual-coastline geography along the Black Sea and Marmara Sea. Projections indicate that a 1.5-meter sea level rise by 2050 could disrupt nearly 70% of port assets. By 2100, a potential 5-meter rise may expose entire port systems and significantly damage rail and highway networks. The most severe scenario for 2300 anticipates up to 15 meters of rise, rendering large sections of infrastructure obsolete and placing over 10,000 built assets in high-risk flood zones. Key logistics hubs like Ambarlı, Haydarpaşa, and Yenikapı are identified as critical risk areas. Beyond flooding, the study highlights secondary impacts such as heat stress on equipment, increased energy consumption, and structural damage from extreme weather. These findings underscore the urgent need for adaptive coastal planning to protect national and international supply chains from macroeconomic vulnerability and operational disruptions driven by global climate instability.
