  1. IWG-Env International Work Session on Water StatisticsVienna, June 20-22, 2005 Water Statistics in the Mekong River Basin

  2. Presentation outline • About the Mekong River and the MRC • Water statistics at MRC • Sustainability issues • Conclusions IWG-Env International Work Session on Water Statistics, Vienna, June 20-22, 2005

  3. The Mekong River BasinSix Riparian Nationsin South East Asia IWG-Env International Work Session on Water Statistics, Vienna, June 20-22, 2005

  4. The Mekong River from source to delta Average flow contribution Upper Mekong (18%) • China – 16% • Myanmar – 2% Lower Mekong (82%) • Cambodia – 18% • Lao PDR– 35% • Thailand – 18% • Viet Nam – 11% IWG-Env International Work Session on Water Statistics, Vienna, June 20-22, 2005

  5. The Lower Mekong Basin • Four riparian countries • Population of 60 million, with rapid increase to 100 million in 2025 • Cambodia, Lao PDR, and Viet Nam are among the poorest countries in Asia and the World • Water is an essentialresource for livelihoods: fisheries, agriculture, energy… • One of the most productive and diverse ecosystemsin the world IWG-Env International Work Session on Water Statistics, Vienna, June 20-22, 2005

  6. The 1995 Agreement Cooperation in all fields of sustainable development, utilisation, management and conservation of the water and related resources of the Lower Mekong Basin IWG-Env International Work Session on Water Statistics, Vienna, June 20-22, 2005

  9. MRC is data hungry! Some examples of current data holdings… • Administration • Climate • Culture • Fisheries • Forestry • Inundation (flooding) • Irrigation • Population & Human settlements • Socio-economics • Soils • Topography • Transportation • Water • Hydro-meteo • time series • Water Quality • Water use IWG-Env International Work Session on Water Statistics, Vienna, June 20-22, 2005

  10. Historical HM time series data • More WL than Discharge • Quality control ongoing • Used for many purposes • Published yearly IWG-Env International Work Session on Water Statistics, Vienna, June 20-22, 2005

  11. Operational HM time series data Forecasting time-series data Near real-time data (telemetric) 2 stations from China IWG-Env International Work Session on Water Statistics, Vienna, June 20-22, 2005

  12. Use of operational HM data • Flood forecasting • Flash flood forecasting • Navigation More about this on Wednesday! IWG-Env International Work Session on Water Statistics, Vienna, June 20-22, 2005

  13. Water Quality Statistics • 100 sites • Monthly samples • Delivered yearly/quarterly • 20 parameters • Analysis by designated labs • QA procedures in place • Round robin analysis • Standard samples • Used to examine spatial patterns and trends in WQ IWG-Env International Work Session on Water Statistics, Vienna, June 20-22, 2005

  14. Water Use Data • ~ 80% of water abstracted is used in agriculture • Measurement of direct water use quite limited in LMB • Estimations calculated (estimated) on secondary data • Secondary data not always available, complete or accurate • Current water use estimations could usefully be improved IWG-Env International Work Session on Water Statistics, Vienna, June 20-22, 2005

  15. Sustainability issues • Technical and institutional mechanisms • Quantity, reliability and timeliness • Continuity: management of data collection networks • Availability of resources and capacity • These issues applies to all MRC data collection (and other organizations…?) IWG-Env International Work Session on Water Statistics, Vienna, June 20-22, 2005

  16. Institutional and technical mechanisms • Improving conditions for data exchange and sharing • Regional forum for D&I exchange and sharing issues (TACT) • Build trust and change attitudes • National data custodianship • Develop procedures, guidelines etc • Support to national agencies • The MRC Information System • Integrated databases • Models • Institutional and technical mechanisms • Capacity enhancements IWG-Env International Work Session on Water Statistics, Vienna, June 20-22, 2005

  17. Quantity, reliability, timeliness • Improvement of HM network density • Climate data especially • Quality Assessment and Assurance • Database review • SOPs, QA procedures, … • Timeliness • Delays in validation and delivery to MRC • Data Delivery Schedule & support to countries • Real-time telemetry networks IWG-Env International Work Session on Water Statistics, Vienna, June 20-22, 2005

  18. Continuity: management of networks • O&M closely related to sustainability of financial and humanresources • O&M cost can be quite substantial • Some national budgets very limited • Limited lasting effect of projects • Situation not unique to LMB… • Gradual improvements expected • Support to countries required in foreseeable future IWG-Env International Work Session on Water Statistics, Vienna, June 20-22, 2005

  19. Limitations in resources and capacity • Access to skilled staff and sufficient funds two critical elements • Present limitations in both is a challenge • Regional HM capacity/skills are in shortage • Big differences between MRC member countries • Clear need to build regional capacity • Long-term commitment required • In recognition of current limitations… • MRC seeks to establish new DSIM Programme • Donor funding sought • 5 year implementation phase IWG-Env International Work Session on Water Statistics, Vienna, June 20-22, 2005

  20. Access to MRC data Internal • LAN/GIS software • Web Portal • Interactive maps • Metadata catalog External • Requests to MRCS • Data publications (Atlas CDs, Yearbooks…) • Online (www.mrcmekong.org) • Flood forecasting/river monitoring • Web Portal IWG-Env International Work Session on Water Statistics, Vienna, June 20-22, 2005

  21. Conclusions • MRC holds substantial amounts of data • Improvements needed to provide data required in the future • MRC data collection depends on regional and national capacity and resources • Lack of resources a limiting factor • Sustainability in management of data collection networks a tough challenge • Implementation of Decision Support and Information Management Programme will be a good step forward IWG-Env International Work Session on Water Statistics, Vienna, June 20-22, 2005
