Marine and oceans are important resources that provide numerous services such as sustaining life, food supply, clean energy, and transportation. However, these valuable resources, along with the habitats they support, are subjected to various anthropogenic pressures, including climate change, population growth, and industrial intensity. In order to create social, economic, and ecological value, sustainable utilization of the sea and its resources can only be achieved through the development and implementation of management strategies based on marine sciences. Recognizing the significance of marine and ocean conservation, the United Nations adopted a framework consisting of 17 Sustainable Development Goals (SDGs) in 2015, which includes the enhancement of sustainable use and conservation of seas and oceans as a priority goal. Effective strategies to combat overfishing, ocean acidification and worsening coastal eutrophication have been emphasized. Türkiye, being a country surrounded by three seas and rich in water resources, is also highly affected by water pollution. Industrial activities, agricultural use, urbanization, population growth, and hydrological conditions contribute to water pollution, making it a significant environmental issue in the country. In this context, the aim of this study is to examine the issues related to seas and marine resources in Türkiye in line with the 2030 Sustainable Development Goals and provide a fresh perspective on what has been done and what needs to be done in the context of Goal 14. The objective is to develop science-based strategies, intensify research capacity, and provide information on the necessary actions to be taken.
