Considering the versatility of the “Environmental Impact Assessment Techniques for Eco-Compatible River-Basin Management” to the East and Southeast Asia, we analyzed the Ise-Bay River-Basin as the objective. In order to grasp the artificial impact empirically, we collected various statistical data with spatial information from 1950 to 2000. From the relationship with the emission reduction of the pollution load using the cleanup approach and the increment since 1950, the following were clarified; 1)·lmprovement of the sewage system diffusion rate and disposal capacity; and 2) Application of “Ecological Services” which consists of natural energy and biological purification. Because of delimitation, funds, and degradation of “Ecological Services”, the foremost tasks are quantification of “Ecological Services” and investigation of “Ecological Services” in marine areas.
