Departed from Narita
Prof. Asano’s accommodation was arranged in Tokyo, for it was convenient for him to visit local universities, research institutes, and administrative agencies which all had invited him for lectures and workshops in advance as well as to meet writers, journalists, and researchers who asked for opportunities to exchange views with the professor.
Through his lectures and dialogues, fundamental differences in the basic attitude toward water resource between the United States and Japan were revealed; the differences are found in ”approaches toward ensuring high quality water”, “whether there are strategic plans”, “the concept of safety” and “publicity measures”. In the United States, the reuse of municipal wastewater from urban sewer systems is often designated in the formal water plans as a sustainable water resource and one of the options to relieve water shortage in areas constantly suffering the problem, such as in the State of California. In fact, the reuse of municipal wastewater is increasing in spite of some unsolved problems such as the difficulty in forming consensus among citizens and certain health risks due to the exposure to potential toxicants.
As for safety measures for the water supply in urban cities, for example, Los Angels City has six major water sources such as off-stream storage, groundwater, recycled water, as well as the three surface water sources from northern California, the Sierra Nevada and the Colorado River. Then, LA ensures water supply for the LA citizens for six months, which is a necessary period of time to restore aqueducts damaged by an earthquake.
On the other hand, in Japan, full-scale, open discussions are rarely seen on water safety/quality issues. However, Prof. Asano’s insightful comments and advice encouraged researchers and administrators in Japan to take a closer look at the issues. Through the discussions with the professor, they came to share the common views towards the issues, which can be summed up to the following five points:
1) Water-related issues hardly attract mass media’s attention in this time of falling population,
2) The issues have not yet surfaced because Japan has not conducted water quality evaluation thoroughly, assuming that Japan is always plentiful in quality water,
3) The issues are hardly addressed in strategic plans,
4) Few experts in the field of water resources are fostered in local universities, although water resources should be recognized one of the most critical local issues, and
5) Publicity measures are not fully organized.
Prof. Asano inspired students and young scientists through the lectures and discussion meetings. Many of the young audience at the Public Works Research Institute (PWRI), the Kitami Institute of Technology, Kochi University of Technology, or Toyama Prefectural University made very positive comments about the lectures. The followings are examples of the feedbacks:
- I have learned from Prof. Asano’s lecture that the US citizens, although they live in one of the most developed nation, are fully aware of the water shortage issues their nation faces,
- After listening Prof. Asano lecturing that water reuse is much cheaper and required lower energy consumption compared to the conventional water transmission, my assumption has been put aside and my vision has been widened,
- After listening Prof. Asano’s lecture, I was more motivated to do my work because I now have a better understanding of our research activities directly contributing to the water resource issues currently looming, or
- I would like to be an expert like Prof. Asano, who has been making significant achievements and globally contributing to the field.
Moreover, the faculty members (professors, associate professors and lecturers) of the visited universities reported that they were greatly impressed by the world’s most advanced water-recycling techniques and the innovative approach Prof. Asano has introduced.
The Japanese administrators (government authorities) reported that they were deeply impressed by the information shared by Prof. Asano regarding the approaches taken by the US government for water resource issues; the information is useful as a reference for the Japanese government to work on the water resource issues in Japan. The followings are some of the approaches taken by the United States:
- Reinforcement of the Infrastructure to enhance the safety of urban city water supply
- Not only risk managements, but also planning water-resource strategies at regular intervals
- Making efforts to draw social attentions to the necessity of investment for maintaining the social infrastructure
- Change in the role of the US government from development to management
The Japanese officials (government administrators) who attended the technical discussion meetings are convinced that information sharing or opinion exchange with the US and EU developed nations will be needed in the future, though most of recent international activities regarding water resource issues have been Asian region-oriented.
As the hosting organization, PWRI believes that Prof. Asano’s contributions to the Japanese society are very promising and respected. With his advice, our water-resource research activities will be widened and diversified. Many scientists and engineers will be fostered in this research area; at the same time leading researchers will be much more motivated to pursue their research topics.
Thanks to Prof. Asano, those in top government offices and academia had precious opportunities to hold technical discussions and to directly exchange opinions with the world eminent professor; he surely exerted considerable influence, which would not be obtained from books, on their notions or attitudes toward research and practice.
PWRI thank JSPS for their generous support for this invitation project. Prof. Asano is scheduled to visit Japan again in FY2007 and share his invaluable insights with those in government offices and academia.
