  1. The economic aspects of water resources information Alexandre Borde C3ED - University of Versailles Saint-Quentin-en-Yvelines International Conference on Water Observation and Information System for Decision Support (BALWOIS) Ohrid, FY Republic of Macedonia, 25-29 May 2004

  2. Statements “There is growing concern that at a time when more precise and reliable information is needed about water resources, hydrologic services and related bodies are less able than before to provide this information, especially information on groundwater and water quality. Major impediments are the lack of financial resources for water resources assessment, the fragmented nature of hydrologic services and the insufficient numbers of qualified staff. At the same time, the advancing technology for data capture and management is increasingly difficult to access for developing countries. Establishment of national databases is, however, vital to water resources assessment and to mitigation of the effects of floods, droughts, desertification and pollution” (UNCED, 1992). “The lack of information and data on sound water management is a serious problem, and is exacerbated by falling investments in national water management systems. Knowledge about groundwater is especially inadequate. Many water managers seem unaware of growing expertise to credibly forecast the effects of climate changes on water resources. There is also extensive experience with solving water problems in developing countries-information that is not being adequately shared worldwide” World Water Council (Guerquin et al., 2003)

  3. Costs Fixed costs Cost Cost of imprecision production Cost of precision High accuracy Low accuracy Optimal information system and the cost function of information production

  4. Water information for decision support: a typology - The inventory of groundwater resources - Understanding cause effects relationships - The benefits of anticipation - Public awareness and education

  5. The information continuum(Hassan et Hutchinson, 1992) supply demand Data collection Data management Data analysis Information for the decision making process Software development

  6. 1. Definition of the issues Agree on the priority issues requiring more information 2. Determination of information needs Determine information needs of decision makers Review 5. Assist the stakeholders Allow the stakeholders to deliver the requested informational products 3. Informational products design Develop informational products corresponding to the needs • Characteristics • Cyclical • Adaptative 4. Repartition of roles Agree of the roles and responsibilities of the stakeholders in the elaboration process The information cycle(adapted from UNEP, 2000)

  7. National Water Data Network (RNDE): an example in France • Partnership between Ministries of Environment, of Health, Meteo France, IFEN, IFREMER, EDF, BRGM, CSP, Water Agencies • Objectives: satisfy EU and international agreements in terms on information provision, give the decision makers the means to assess the situation and the trends, ensure a data patrimony costly to produce, create awareness on data producers and make it benefit to the public • A common language: SANDRE and thematic databases: Hydro, Pluvio, Quadrige, BHP, BNDE
