Global Water Supply-Demand Assessment
Summary
Sustainability on water supply and demand issues attracts attention as one of global scale issues. In this proposal document, the macroscopic balance of water supply and demand with the linkage of an integrated assessment model, GRAPE (Global Relationship Assessment to Protect Environment) is preliminary assessed, and the possibility of a food supply constraint is indicated.
A literature survey on the water-energy nexus, such as efficient water utilization for energy supply and efficient energy utilization for water supply is conducted to obtain discussion points and possible solutions regarding sustainability, including the relationship between water supply and energy. Political countermeasures are proposed to assist the resolution of water-energy nexus issues, as well as to improve the resiliency of the water system foundation to various kinds of stresses.
