The Tonle Sap Lake is an important wetland area of Cambodia and Southeast Asia. However, wetland is under threats from infrastructure development, land conversion, water withdrawals, pollution, increased population pressure and hydropower dams building and affect the livelihoods of rural communities. The governance of wetlands is a key action in sustaining the wetland services and the well-being of people. The ＂wise use＂ is a key concept of wetland governance. Although there is considerable research on the ＂wise use＂ and the application of this concept in wetland management, its application in Tonle Sap remains challenged. Hence, this article addresses the question： How wise use is operationalized for the governance of wetlands in Tonle Sap and what implication it has on the wellbeing of peoples and the ecosystem services？ It uses a literature review and a case study to analyze the wetland governance in Tonle Sap, Cambodia. The article describes the wetland governance based on ecosystem services, the direct and indirect driver affecting wetlands and how it threatens the livelihood security of wetland dependent communities. It concludes that the officially wise use of wetlands is a problematic in Tonle Sap.展开更多

However, the participant of consumers challenges the current power systems with system integration and cooperation and security issues. In this paper, the authors introduce a service-oriented approach to AMI aiming at solving the intercommunication problem and meanwhile providing a trust and secure environment for smart grids. In this approach heterogeneous systems expose services to the network. System integration and cooperation are done through service composition. A generic service interfacing method is designed to develop standardized services for heterogeneous power systems. Moreover, role-based access control mechanism is used to guarantee the secure access to smart grids. With the seamless communication between consumers and power systems and among power systems themselves, this service-oriented AMI can associate consumers with actual system workload and furthermore support the intelligent running of power systems.展开更多
