Abstract:

Recently,important land use changes have occurred in the Black Sea coastal regions of Ístanbul due to urban growth and population increases.The objective of this study was to determine changes in land use in the Black Sea coastal regions of?stanbul between 1987 and 2007.Landsat 30 m satellite images from 1987 and 2007 are used in the study.The study area is 1000 m in width from the coastline to the land and the study has been carried out using the controlled classification method to classify areas into residential,agricultural, forest,bare land,brush/grassland,and lake/pond land classes.Land use changes between 1987 and 2007 were analysed in detail.Residential areas of the Black Sea coastal regions of Ístanbul increased by 122%over the two decades.Also an increase of 55%in agriculture areas was observed,while there were decreases of 26%in forest areas and 15%in free land. A 21%increase in the area of brush and grassland took place.Furthermore 79%of the study area was covered by residential areas in 2007.It is probable that pressure on the Ístanbul coastal regions will continue due to migraton and rapid urbanization.Therefore,Istanbul's Black Sea coastal regions should be maintained using a sustainable coastal management plan.
