Relationship Between Green Areas and Urban Conservation in Historical Areas and Its Reflections: Case of Diyarbakir City, Turkey

City planning is essential for providing physical environment for better community life and for providing green areas, while conserving historical heritage is an important achievement in city planning, particularly for historical cities such as Diyarbakir city. The focus of this paper is to outline how increasing the ratio of green area in the city centre of Diyarbakir, Turkey, with a land-use betterment model exemplified sustainable urbanism. We observed an applied urban design project that included both opening up free space to the public and increasing the amount of available green area. The project addressed an area adjacent to the Diyarbakir city walls, which are important not only for their history but also as reflections of the urbanization process of Diyarbakir from prehistoric time to the twenty-first century. We have noticed that changes in the design area provided understanding of the city planning by public and supplied more green areas for children and women. Thus, the city became more desirable and more sustainable.
