Study on Nationwide Water Resources Development and Management in the Socialist Republic of Vietnam CHAPTER 1 SCOPE OF THE STUDY 1.1 Background of the Study Water resources in Vietnam are characterized by severe water shortage in the dry season and, on the contrary, serious flood damages in the rainy season. The water shortage in the dry season causes not only irrigation domestic and industrial water supply problems but also serious water pollution and saline water intrusion. Flood damages in the rainy season including agricultural production loss, human lives and important assets in densely populated urban areas are being accelerated due to recent remarkable urbanization. As such, solution of the problems is of keen necessity of Vietnam, and several water resources development projects comprising mainly multipurpose dam based projects have been proposed by each province. However, since the proposed projects are not integrated as a basin-wide water resources development, the Ministry of Agriculture and Rural Development (MARD) has difficulty to determine the implementation sequence for these water resources developments. In order to overcome these constraints, the Government of Vietnam has come to conclusion that an integrated approach to water resources development and management is unavoidable, and had a strong intention to carry out a study on nationwide water resources development and management. In order to materialize the study, the Government of Vietnam requested to the Government of Japan the technical assistance of the Study on Nationwide Water Resources Development and Management Master Plan (the Study). In response to request of the Government of Vietnam, the Government of Japan decided to conduct the Study within the general framework of the technical cooperation between the Government of Japan and the Government of Vietnam signed on October 20, 1998. 1.2 Objectives of the Study The objectives of the Study are: (1) To formulate a master plan for nationwide water resources development and management, (2) To conduct a feasibility study for selected priority projects, and (3) To pursue technology transfer to counterpart personnel in the course of the Study. FINAL REPORT 1-1 Phase 1 Study on Nationwide Water Resources Development and Management in the Socialist Republic of Vietnam 1.3 Study Area The Study covers the following 14 major river basins: 1) Bang Giang and Ky Cung River basin 2) Red and Thai Binh River basin 3) Ma River basin 4) Ca River basin 5) Thach Han River basin 6) Huong River basin 7) Vu Gia-Thu Bon River basin 8) Tra Khuc River basin 9) Kone River basin 10) Ba River basin 11) Sesan River basin 12) Srepok River basin 13) Dong Nai River basin 14) Cuu Long River basin Location map of the above 14 major river basins is shown in Figure 1.1 1.4 Scope of the Study The Study has been undertaken in the following manner in the two phases: Phase I : [Basic Study and Formulation of Master Plan] a) Formulation of a master plan for nationwide water resources development and management in 14 major river basins Phase II : [Formulation of Integrated River Basin Management Plan(s) for the Selected River Basin(s) and Feasibility Study on Priority Projects] a) Formulation of an integrated river basin management plan for the Huong River basin (Phase 2-1) b) Formulation of an integrated river basin management plan for the priority river basin selected from 14 river basins (Kone River basin, Phase 2-2) c) Feasibility study for the priority projects to be selected from the priority river basin (Phase 2-3) FINAL REPORT 1-2 Phase 1 Study on Nationwide Water Resources Development and Management in the Socialist Republic of Vietnam 1.5 Implementation Organization Institute of Water Resources Planning, Ministry of Agriculture and Rural Development(MARD) act as the counterpart body to the JICA Study Team and also as the coordinating body in relation with other governmental and non-governmental organizations concerned in Vietnam for the smooth implementation of the Study. The JICA Study Team is headed by the Team Leader who is responsible for maintaining a close liaison with the MARD, JICA and agencies concerned. He is also responsible for planning activities and monitoring the progress of the entire study for ensuring its timely and efficient completion. The members of the Study Team and the members of the Advisory Committee are presented in Table 1.1 The Steering Committee was organized in February 2002, chaired by the Vice Minister of MARD. The Committee consists of MARD, Ministry of Planning and Investment, Vietnam National Mekong Committee and Peoples Committee related to the Study. The members of the Steering Committee are presented in Table 1.2 1.6 Study Schedule and Activities (1) General Schedule Phase I : Basic Study and Formulation of Master Plan during a period from September 2001 to July 2002, Phase II-1 : Formulation of Integrated River Basin Management Plan for the Huong River Basin, during a period of October 2001 to July 2002, including 1) 1st Works in Vietnam 2) 1st Works in Japan. Phase II-2, II-3 : Formulation of Integrated River Basin Management Plan for the Selected River Basin(Kone River basin) and Feasibility Study on Priority Projects during a period of August 2002 to September 2003, including 1) 2nd Works in Vietnam 2) 2nd Works in Japan 3) 3rd Works in Vietnam 4) 3rd Works in Japan. FINAL REPORT 1-3 Phase 1 Study on Nationwide Water Resources Development and Management in the Socialist Republic of Vietnam (2) Activities in the Works in Vietnam In accordance with the objectives of the Study and schedule, the works in Vietnam were conducted in October 2001 through March 2002 for Phase I, and from August 2002 through March 2003 for the Phase II study.
