It provides an overview of the BDP formulation, together with information about the planning process and its knowledge base, tools and routines. The library incorporates the essence of more than a hundred technical reports, working papers and other documents. It consists of 15 volumes: 1 The BDP planning process 2 Sub-area analysis and transboundary planning 3 Sub-area studies (including 13 sub – volumes) 4 Scenarios for strategic planning 5 Stakeholder participation 6 Data system and knowledge base 7 MRCS Decision Support Framework (DSF) and BDP applications 8 Economic valuation of water resources (RAM applications) 9 Social and environmental issues and assessments (SIA, SEA) 10 IWRM strategy for the Lower Mekong Basin 11 Monographs. March 2005 12 Project implementation and quality plan 13 National sector reviews 14 Regional sector overviews 15 Training The work was carried out jointly by MRC and the NMCs with comprehensive support and active participation by all MRC programmes and more than 200 national line agencies. Financial and technical support was kindly granted by Australia, Denmark, Japan, Sweden and Switzerland. The library has been produced for the purpose of the BDP and is intended for use within the BDP Programme. The work was done from 2002 to 2005, and some information may already have been superseded by new developments and new knowledge. The library does not reflect the opinions of MRC nor the NMCs. It is hoped that the work will contribute to the sustainable development of water resources and water- related resources in support of the MRC vision of 'an economically prosperous, socially just and environmentally sound Mekong River Basin'.
