In the Shimabara area which was damaged by the volcanic eruptions of the Mt.Fugen in Unzen between 1990 and 1995, many disaster prevention facilities have been constructed in sand erosion control districts to improve the regional safety. The sand erosion control districts however are extensive and some are located in a national park. Furthermore, since many of the sand erosion control districts are closely located to local residential areas, and the frequency of debris flows was decreasing, requests were made by the local residents and municipalities to utilize the districts for the rehabilitation and development of the Shimabara area. In response, a plan was established which addresses the needs of the local communities by using part of the sand erosion control districts for such a purpose without sacrificing their functions, and projects were carried out in stages in accordance with the plan. Since there is little precedence for the use of sand erosion control districts for purposes other than the original intent, the results of the attempt in the Shimabara area are expected to yield important insights for future application of this approach. This paper summarizes the progress and outcomes of the use of the sand erosion control facilities for rehabilitation and development between 1995 and 2004, and presents the results on the public opinion and recognition of and needs for the use of the districts for such a purpose which have been obtained through a questionnaire survey conducted on the local residents and tourists. Finally, the paper presents a proposal on the implementation and publication method and coordination of related parties for the use for such a purpose.
