A co-governance program for five waters (CPFW), including sewage treatment, flood prevention, drainage, water supply and saving, is an innovative concept in water resource management. It includes current and near future system projects and advanced management policies for water utilization and protection. In this paper, the scientific connotation of CPFW is explained by multidisciplinary theory. Based on current guidance and technology, evaluation targets and water management countermeasures are specified. Combining hydraulic engineering and their characteristics, operable approaches for CPFW are suggested for projects' designation and construction. These approaches of CPFW are applied in a typical area. Systematic projects are composed of sewage interception projects, efficient water supply projects and hydraulic projects with ecological engineering. With the guidance of CPFW, all projects are connected together and their integrated benefits are evaluated in water saving, sewage drainage, increase in environmental capacity and ensuring security. The results show the CPFW is valuable and available both in theory and in practice. [ABSTRACT FROM AUTHOR]

To achieve an efficient use and allocation of limited water resources and thus resolve increasing water use conflicts due to fast rising societal water demands, in 2000, the Chinese government started a management strategy of 'Construction of a Water Saving Society (WSS)'. It is guided by the principle that socio-economic development should consider the carrying capacity of the ecosystem and focuses on institutional innovation, building on the water rights concept. This paper explores the innovation process during the transition towards WSS by investigating the development course of the innovation process during the transition towards WSS, and the adaptive capacity of the existing water management regime underlying the innovation process. Accordingly, an analysis framework consisting of three types of governance activities and factors determining a regime's adaptive capacity was developed, based on the theory of transition management and adaptive governance. The Tianjin and Zhangye WSS experiments were selected for a deep understanding of local innovations. It is revealed that co-evolution of all three types of governance activities that are claimed to be essential for transition has taken place. However, the current adaptive capacity of the regime still needs further enhancement to support the transition towards the desired WSS in China. Finally, some general insights are provided for policy innovations in other political economies. [ABSTRACT FROM AUTHOR]

As China continues to sustain high rates of economic growth, it is important to better understand patterns of resource use within the Chinese economy and the vulnerability of its growth to resource scarcity. This paper examines relationships between two of China's scarcest resources--energy and water--focusing on the energy implications of water use. Based on an analysis of economy-wide resource flows using China's input-output tables, we draw three overarching conclusions: First, the energy used both directly and indirectly in providing non-agricultural water currently represents only a small fraction of China's total energy consumption. However, this share is set to increase as the country expands its water treatment capacity and hydraulic infrastructure. A lifecycle assessment framework for evaluating these projects would aid policymakers as they choose between more and less energy-intensive modes of water provision. Second, energy-water price interactions are currently of little relevance to policymakers because water prices are low, but the high electricity-intensity of water treatment facilities and their need to recover costs may change this situation. Third, water "migration" from agriculture to non-agricultural uses will have important energy dimensions, which will be important for policymakers to bear in mind as they design water pricing and conservation efforts.
