Background The area of Karahayit & Pamukalle represents one of the most important tourist attraction area in the Agean region of Turkey. Karahayit, a UNESCO site since 1990, is famous for the archaeological remains of the ancient city of Hierapolis (from the Hellenic and Roman period) and its thermal water resources.The area falls under the statutory protection of the Special environment Protection Council of the Ministry. However, the use of thermal water is not regulated or controlled. Excessive usage, unauthorised wells, and improper management of water after use pose a serious environmental problem, which is likely to lead to the depletion of the resource and the loss of this unique tourist attraction and source of income for Karahayit. Objectives The project's objective is to preserve the thermal water resources of the area of Karahayit & Pamukalle and exploit their therapeutic qualities in a sustainable manner in order to strengthen tourism and the local economy. The project aims to develop and start implementing fully documented plans to regulate the use of thermal waters and ensure the sustainability of thermal water resources, whilst thermal health facilities and therapeutic tourism is developed.
