This study focuses on the impacts of the Syrian refugees on Turkey. To understand the effects of refugee influx on Turkey, four different field studies were conducted in the provinces of Adana, Osmaniye, Hatay, Kilis, Gaziantep, Sanliurfa, Mersin and Kahramanmaras¸ during a period of three months. In these provinces, NGOs, local authorities, community leaders, academics, members of chambers of commerce and industry, local citizens and Syrian refugees were interviewed. This report, titled “Effects of the Syrian Refugees on Turkey” was prepared with observations and data collected from field studies. First, an overview of the situation of Syrian refugees in Turkey is presented. In the second chapter, the effects of the Syrian refugees on Turkey will be examined in relation to the economy, social life, security and politics. Because of the unique nature of these effects in each city, the third chapter is dedicated to a detailed examination of different provinces. In the last chapter, a general conclusion of the study and recommendations for improve- ment of the Syrian refugees’ situation will be presented.
