論文概要: Water security is widely recognized as an important and increasingly urgent challenge in policy and academic circles. In order to benefit achieving water security in the future, it is necessary to reorganize the initiate, connotation and extension, and the evolution of water security. Meanwhile, water security is expected to integrate water quantity, water quality, water disaster, and economic-socio factor.

CHAPTER 1 presents research background and significance of water security. In addition, the significance of different water management approaches to achieve water security is described and the related studies have been reviewed. Successively, the goal of this study is proposed.

CHAPTER 2 describes the methodology and motivation in the whole thesis.

IN CHAPTER 3, water ecological footprint method has been applied to demonstrate how the sustainable utilization of water resources can be realized.

IN CHAPTER 4, ecological footprint method is applied to demonstrate the sustainable utilization of clean and safe water in Japan taking water quality in account. Consequently, the rational policies and measures associated to water resources should be implemented to ensure water sustainability in Japan.

IN CHAPTER 5, the current situation of water disaster security of “sponge city” in China has been evaluated so as to lay the foundation for further study of sponge city construction and urban flood management. Recommendations for improving the urban resilient performance of different classes are made to help the decision-makers design and construct sponge city under local conditions.

CHAPTER 6 integrates water resources, water environment, and water disaster to measure the secure state of water security system. Water sustainable management in Japan and Guizhou of China is determined to be at a relatively adequate level that meets the requirements of sustainable development.

CHAPTER 7 discusses water security system programming of economy - water resource - water environment - water disaster - population, and develops a system dynamics (SD) model by which several typical scenarios are proposed for comparative analysis.

In CHAPTER 8, the conclusions of whole thesis is summarized.
