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

In order not to reduce this electrical energy, it must be stored. The sensible energy storage is currently the pumped storage power plants. As the mountain ranges for conventional pumped storage power plants with drop heights of H 〉 600 m are strictly limited, the development of low potential pumped storage power plants has begun. Increasing the capacity of pumped storage power plants with regard to the wind power plants is urgently needed. In this paper, it is shown using the example of an unneeded port facility, how a port facility can be used after low conversion as a test facility for low potential pumped storage power plants and at the same time for the testing of hydro-kinetic turbines. This type of pump storage power plants does not save the energy due to large drop heights, but primarily due to the large volume flow of water.展开更多
