TI  - ANALYZING THE URBANIZATION IN THE PROTECTION AREA OF THE BOSPHORUS
AB  - Istanbul, being one of the oldest and crowded cities in the world bridging the Asia and Europe continents,is ranked as the 15th populated mega city among the 75 largest metropolitans in the world as a result of the rapid populationgrowth since the year of 1950. The stated growth caused a significant need for housing, therefore new settlements havebeen built in and around the city threating water resources, protected areas, and sensitive lands such as agricultural areas,forests, wetlands in the city. As a result of these adverse developments, the Bosphorus zone, which has a historical andgeographical importance for Istanbul, was declared as a protected zone for stopping the threat of unplanned urbanizationalong the Bosphorus. The Bosphorus area were divided in to two protection zones as Back View and Front View Zones bythe laws in terms of the stated protection plan. The main goal of this study is to examine the changes in settlement areas inthe protected zones of Bosphorus specifically in Sariyer District. In this context, Landsat imageries dated 2005 and 2017were used to determine the urban sprawl during 12 years in the protection zone of Bosphorus. The results of the studyintroduced 10% decrease in the forest and green lands from 2005 to 2017 while 8% and 11% increase in settlements andthe other land use classes respectively. In order to perform more detailed analyses of this change, a detailed study wasperformed for Front and Back View Zones of Bosphorus in Sariyer district using 2005 and 2017 dated IKONOS satelliteimages. The map of Sariyer district produced in 1960 was considered as the reference data source as well as image fordetecting the changes in the study area during 57 years in two periods. The results of the study outlined that the settlementsin the study area increased 173% and 142% for two periods from 1960 to 2005 and from 2005 to 2017 respectively. Theincrease in settlement areas caused a decrease in forests and green lands in the study area. In particular, the study introducedthe illegal settlement area increase in the protection zones of the Bosphorus based on the Bosphorus Law No. 2960 inSariyer District.
