The purpose of this work was to investigate how integrated coastal zone management (ICZM) can help the problems of coastal resource use in Turkey. Therefore, the problems were identified first. Secondly, the key concepts of ICZM were determined through a literature search. This search pointed out that ICZM is a valuable tool for dealing with the problems of coastal resource use in Turkey. ICZM is a tool for the management of coastal environmental resources in a way that is in line with the principle of sustainable development. Accordingly, science is supposed to play a major role in both the preparation and implementation of ICZM projects. Therefore, the final stage of this work intended to show how science can be employed in the decision making under an ICZM progam. For this aim, the dispute over the sites of marine aquaculture fish cages in Bodrum, Turkey was chosen as the use case. The main reason for this choice was the popularity and real-world nature of the case. Since Bodrum is a highly touristic spot in Turkey, the case has been the subject matter of an ongoing dispute. As the first round in the dispute, the Ministry of Environment and Forestry (MEF) issued a decree in May 2007 requiring that all the cages be moved offshore. The farmers went to court and won the case. Nevertheless, the issue does not seem to be settled in any way. In our view, the problem has stemmed from the lack of employing science in the very first place. That is. if there had been ICZM programs in place, all the decisions such as sites for fish cages could have been taken more scientifically, with the consent of stakeholders. Moving on from this point, a multi-criteria evaluation (MCE) was performed in IDRISI GIS to show that scientific decision making is possible. The analysis has also shown that the scientific results agree with neither the current use nor the recent ruling of the MEF.
