Hello, this is Naomi from Japan. Water issues in this archipelago is not that much recognized as regional issues as we do not share directly the source with other nations. Though I guess that is one reason why there still remains rather too relaxed approach about the matter especially for urban planning. As this is a country of Confucian tradition, the decision makers in governments are often over 60 years old and it is not rare to find them without sufficient knowledge of sustainability and water ... And it seems to me it did not occur at all during their planning process to consider a possibility that concreting greenery and sand beaches can change dramatically the underground water system even in a tiny space of a city. Then, those civil engineers found flooding in downtown almost weekly during summer after torrential rain. In the end, these days, I concluded it is the matter of education not only for young people, but also for grandparents who graduated their colleges 50 years ago, and happen to sit for the top tables of offices.
