Summary

1) This project was implemented by the Kosuge/Tama River Headwaters Institute, which was set up under the “Community Revitalization Program” of the Cabinet Office (implemented in FY 2008–2009). It used a 1/25000 infrastructure map database system, which covers the whole Tama River basin.


2) Thanks to the supervision and advice of experts, we presented the research results of the Tokyu Foundation for Better Environment and the citizen activities centering on the waterfront recreational school in a visualized format. We also digitalized the simultaneous water quality studies of the Tama River and the Tama River headwaters resources survey into databases. We were able to publish 121 cases of the academic study results that the Tokyu Foundation for Better Environment sponsored in the fourteen years from 1995 to 2009 on the WebGis website.


3) With the advancement of global warming, there are signs causing concerns about the deterioration of cedar, cypress, and other forests on the watershed. We conducted an investigation of resources and digitalization of data in this field. We also worked on improving the search and listing function, browsing, bidirectional registration, and other operational functions, and held technical seminars.



As a result of the above,


1) if an information network is built using the geographical information system (GIS) from the headwaters to the estuary, it will be possible to provide a wide range of real-time information to citizens, businesses, educators, municipal governments, and river managers who are interested in preserving the natural environment of the Tama River;


2) if the “Tama River Basin Environment Database” is developed, it will be possible to build a “Tama River Field Museum” using the geographical information system as platform. Then any citizens in the basin can obtain information anywhere in the form of map information, thus making them feel closer to the Tama River and deepening their understanding of the Tama River;


3) if the map information of the Tama River becomes easily accessible to citizens, it can deepen their understanding of and interest in the Tama River, can call for their attention to the environmental protection of the Tama River and its watershed, and can encourage participation and cooperation in activities to improve the whole basin; and


4) if the results of researches and studies of the Tama River conducted so far can be presented in a visualized format and as map information, it can deepen our understanding of the Tama River and it becomes possible to make the best use of the study results.
