Abstract
The aim of this study is to establish an urban sustainability evaluation system by the elementary school district from the viewpoint of Triple-Bottom-Line (TBL: Environment, Economic and Social). With applying it to the Nagoya metropolitan area, following results are obtained. Firstly, it was shown that the average levels of all TBL indicators would deteriorate in the next 40 years. Secondly, risk factor which spoil urban and regional sustainability was analyzed with revealing the spatial distribution of TBL quantitatively at the year of 2005 and 2050. And, the results showed that the economic and environmental indicators would decay mainly in the agricultural, forestal and some part of the suburban area where baby boomers acquired houses. In addition, disparities of the economic and environmental indicators among all districts were expected to widen. Finally, future urban restructuring scenarios, in which above results are considered, were evaluated based on the TBL perspective.
