An assessment of Turkish deltaic landscapes regarding environmental conservation and sustainable management--a case study of the Kizilirmak Delta.

Deltas, as macro and micro biological systems at high productive levels, are the natural reserve areas of the world. Those in Turkey present the international importance landscapes as to the various ecosystem characteristics and land use patterns. Nevertheless, these areas are currently facing many problems such as biodiversity loss and environmental degradation owing to coastal settlements and pollution factors. This paper describes the factors responsible for the main features and degradation types of the Deltaic landscapes and their impact for future land use. It also deals with : an overview of the Kizilirmak Delta, one of the most important Deltas along the central part of Black Sea Region (Turkey); presents major ecosystem of it; identifies land use pattern and discusses the threats by environmental and human induced disturbances. The most considering feature of this Delta is to show the largest and most significant wetland area of Turkey which has been able to protect its natural beauties on the Black Sea Coasts. A Delta plain of 56000 hectares extends through the area at the north of the Samsun-Sinop highway. The ecological system of the Delta is extremely rich in terms of its biological variety as well as its fauna (especially number of bird species). But, the Delta including terrestrial areas close to the water resources and the vegetation between aquatic and terrestrial systems, has been constantly modified by human activities. Consequently, some considerations for environmental conservation and sustainable management were put forward for the future generations.
