1. Study on the relationship between water use and environment in a basin with poor water resources.<\/p>\n\n\n\n

\u3000The uneven distribution of precipitation caused by global warming is expected to intensify, mainly in Asia and Oceania, including Japan In areas of reduced precipitation, more efficient water use will be required for food production. Therefore, it is necessary to have an understanding of the proper use of water, and to study ways of sustainable utilization of water, and biological resources. In this study,we analyzed water and material circulation at the basin scale for the watershed of the Seto Inland Sea Region, which has poor water resources. We elucidated the mechanism of water pollution ecological alteration from river to marine areas caused by water use in terrestrial areas. Based on the results obtained, we aimed to present a water use system for sustainable biological production,which imposes a smaller burden on natural substance circulation and ecosystem.<\/p>\n\n\n\n

2. Study of interrelationship between water circulation in the basin and the food chain in coastal waters.
\u3000Organic pollution in the basin significantly changes the composition of substances transported by the river to the coastal areas. There is a relative decrease in the nutrients necessary for primary production in the sea, and a relative increase in the organic matter in the form of freshwater algae. This change disturbs the biological production and food chain in the coastal waters. In this study, we quantitatively analyzed the dynamics ( predation, decomposition, and outflow) of freshwater algae in rivers, tidal flats, and coastal waters. Further, we quantitatively clarify the contribution of freshwater algae in the food chain in the Seto Inland Sea. Thereafter, we proposed a mechanism to balance biological production between land and ocean areas.<\/p>\n\n\n\n

3. Development of Assessment method of Water Environment – Water \/Substance Environment Map.
\u3000Conventionally physical parameters, such as water temperature and water level have been used in water circulation research. Recently, however, tracer technologies using various stable isotopes and major\/trace elements have been proposed. Using these substances as tracers enables the effective tracing of water circulation processes and substance dynamics. The feature of this research is that it integrates various traceability methods and practices to monitor basin water conservation.<\/p>\n\n\n\n
