A Study On The Allocation Of The Water Resources Of Lancang-Mekong River

With the continuous increasing of world population and world economic development, it has caused the global shortage of water resources and continuous utilizing conflict of trans-boundary water resources. This brings great political and economic pressure on the utilization of freshwater resources to each country. Lancang-Mekong River is an import river in Asia and it flows through China?Burma? Laos?Thailand?Cambodia and Viet Nam. The six countries within the watershed have different water targets and form the game in utilization competition for trans-boundary water resources in Lancang-Mekong River. The competition and the cooperation of basin countries are noticeable. Basin countries are looking for acceptable and the most feasible programme for utilization of trans-boundary water resources corresponding to the actual situation of the Lancang-Mekong River basin countries through dialogue and cooperation.For the reasons of protecting the public interest of basin and providing a clear idea and feasible methods for avoidance and resolution conflict problem of trans-boundary water resource utilizing, this dissertation focus on the first principles of trans-boundary water resources—equitable and reasonable utilization, and makes a thorough study on problems of trans-boundary water resource allocation in Lancang-Mekong River. This dissertation is divided into six chapters.Chapter 1 analyses the theoretical and practical significance of problems about trans-boundary water resource allocation in Lancang-Mekong River. It aims to provide research background of the subject.Chapter 2 analyses situation and tendency at home and abroad of multiple allocation and management models formulated according to watershed planning for trans-boundary water resources in Lancang-Mekong River. It also explains the problems of existing planning mode and seriousness of competitive utilization and conflict of trans-boundary water resources caused by these problems. Then it points out the necessity of watershed integrated planning for trans-boundary water resources in Lancang-Mekong River.Chapter 3 discusses organization framework of unified management and development of trans-boundary water resources, according to the current allocation mode of Lancang- Mekong River. It analyses allocation patterns of trans-boundary water resources in the Lancang-Mekong River and researches overall watershed planning model of trans-boundary water resources. In the model, it analyses weight matrix and benefit difference matrix of multiple development objectives for different countries to make sure the central objectives of watershed integrated planning to be researched in the following chapters——water rights allocation for agricultural irrigation and cooperative game analysis for hydropower project development.Chapter 4 makes game theory analysis on agricultural irrigation water rights allocation for five countries in the Lancang-Mekong River according to overall watershed planning model of trans-boundary water resources. First, it analyses theory of water right management and definition of water right. Then it discusses economic influence of water right trade and uncertainty allocation method in the Lancang-Mekong River and allocates irrigation water rights for five countries using proportion method and Two-Part allocation method. Then it solves the game problem and analyses the benefit of the game. Finally it compares the results between cooperation game and other methods of water resources allocation and gets a conclusion that multinational cooperation can get more benefit than working alone by each participating country. This is an important innovation of this dissertation.Chapter 5 is based on the model of overall watershed planning and for the situation about what influence and impact the upstream countries will bring to downstream countries when they develop hydropower in the upstream, which is concerned and worried universally by basin countries in Lancang-Mekong River, Chapter 5 computes impacts and benefits of hydropower development by China in the upstream of Lancang-Mekong River on seven development indicators of trans-boundary water resources utilization made by six countries in the basin, using computing method of benefit difference matrix of trans-boundary water resources allocation. It solves respective specific quantitative indicators of seven development objects in basin countries. It computes basin-wide annual energy production and power generating benefits according to capacity of hydropower development of each country. Then it takes Laos for example, makes a cooperative game analysis on overall benefit. Through these computing results, it verifies that the hydropower development in upstream countries can do more good than harm to the multiple development indicators in downstream countries and cooperative benefit is better than benefit of working alone.Chapter 6 is based on research of the Lancang-Mekong cooperation in trans-boundary water resources development, analysis the relationship and the interaction and the development trend between the Lancang-Mekong River basin constructs "The Belt and Road" strategy and the Lancang-Mekong River water resources trans-boundary cooperation. Then, it emphasizes the importance of the overall planning innovation model as a whole basin is used to research the trans-boundary water resources cooperation mode of the Lancang-Mekong River, and how it plays a positive role on the Lancang-Mekong River Basin constructs "The Belt and Road" strategy. Finally, from the point of view of China's own comprehensive benefits, it points out that China's position and solution should be held in the development of hydropower development in the Lancang Mekong River Basin. At last, it summarizes the research conclusions and proposals of the dissertation, and gives prospect on the continuing study.
