Abstract

The discussions on and monitoring of the conservation/restoration of Watarase-yusuichi (flood control basin in English)registered as the Ramsar site are going on, with active participation of stakeholders. This is the challenge to the integrated management of wetland. However, Watarase-yusuichi is a part of the Watarase River, the basin of which once suffered serious damages by the Ashio Copper Mine Pollution Case, and has been affected by continuous sand and flood disasters. The Ramsar Convention requires the integration of wetland conservation and wise use into river basin management through ecosystem-based approaches. Since the Basic Plan of the conservation/restoration of Watarase-yusuichi focuses solely on the excavation of the reservoir, the option of reconnecting the wetland with rivers needs to be considered. By utilizing multifunction of ecosystem including water flow, adaptive management possibly balances flood control and conservation/restoration. The management of Watarase-yusuichi, therefore, has possibilities and advantages in the implementation of Integrated River Basin Management (IRBM),as the Watarase River Basin management, because ① there exist certain institutions where stakeholders of the river basins actively participate, ②common historical and geographical backgrounds shared among the stakeholders living all along the Watarase River Basin require river basin management, and ③a variety of citizen's actions are practiced throughout the whole river basin. Such integration would be a good model of the wise use of wetland, as well as a historical lesson for us and for developing countries.
