Outline of Final Research Achievements

Securing water resources and reducing water-related disaster are critical to develop sustainability in society. Global database on water surface, including lakes and rivers, and on glacier particularly debris coverage were developed based on earth observation from artificial satellites, ground water model and river dynamic model were revised and incorporated with land surface/hydrologic models, and future projections how available freshwater resources, water scarcity, and flood damages will change associated with climate change were estimated. At the same time, the changes in water demand in agricultural and urban sectors driven by demographic and socio-economic developments were analyzed and formulated, and contributed to estimate future changes of saving water demand by food trade and health risk with developing water infrastructure.
