1. TOWARDS A GLOBAL WATER CYCLE COMMUNITY OF PRACTICE RICK LAWFORD GEO UIC MEETING OTTAWA SEPTEMBER, 2006

2. MAJOR IMPACTS OF THE GLOBAL WATER CYCLE : THE GLOBAL WATER CYCLE IS RESPONSIBLE FOR: MAJOR UNCERTAINTIES IN CLIMATE CHANGE PROJECTIONS DUE TO CLOUD PARAMETERIZATIONS MAJOR REGIONAL AND GLOBAL ISSUES RELATED TO SECURITY, STABILITY AND SUSTAINABILITY. DEMAND WILL EXCEED SUPPLY OVER MANY AREAS BY 2030 – 2050. (After J. Rodda) WATER RESOURCES (KM 3 ) TOTAL ACCESSIBLE POLLUTION LOSS

3. Observations and Assimilation Products ONE ROLE FOR DATA IN THE DECISION PROCESS IN THE WATER SECTOR. EXAMPLE OF THE ROLE OF WATER DATA IN WATER MANAGEMENT STRATEGIES

4. OBSERVATIONS IMPROVED CAPABILITY TO ASSIMILATE AND PREDICT INTEGRATED DECISION SUPPORT SYSTEMS THE VISION: A NEW EPOCH OF WATER MANAGEMENT IN OUR LIFETIMES THAT IS FACILITATED BY OBSERVATIONS. E W N Q P MCMC Land Atmosphere cf. Sorooshia n

6. OBJECTIVES (I): 1.TO SUPPORT THE WATER SECTOR BY FACILITATING THE DEVELOPMENT OF APPROPRIATE OBSERVATIONS AND THE USE OF DATA PRODUCTS DERIVED FROM THESE OBSERVATIONS. 2. TO MAXIMIZE THE ECONOMIC BENEFITS IN THE WATER SECTOR COMING FROM EARTH OBSERVATIONS. 3.TO MAXIMIZE THE BENEFITS OF EARTH OBSERVATIONS FOR ENVIRONMENTAL ENHANCEMENT AND SUSTAINABLE DEVELOPMENT OF WATER RESOURCES. 4. TO DEVELOP ASSESSMENTS AND STATEMENTS ABOUT THE BENEFITS OF WATER CYCLE OBSERVATIONS. 5. TO PROVIDE A FORUM FOR DISCUSSION ON NEW APPROACHES TO WATER MANAGEMENT NEEDED TO MORE FULLY UTILIZE EARTH OBSERVATIONS AND PRODUCTS.

7. 6. TO PROVIDE A FORUM FOR THE WATER CYCLE COMMUNITY TO DEFINE NEEDS FOR FUNCTIONS RELATED TO THE DEVELOPMENT OF ANCILLARY PRODUCTS AND NEEDS. 7. TO FACILITATE THE LINKAGES BETWEEN THE WATER SECTOR AND OTHER SOCIETAL BENEFIT AREAS FOR THE DEVELOPMENT OF DATA PRODUCTS. 8. TO IDENTIFY THE RESEARCH NEEDED TO DEVELOP AND EXPLOIT THE OBSERVATIONAL CAPABILITIES AND DATA PRODUCTS.

8. BENEFITS: 1.USERS WOULD BE EDUCATED ON THE DATA, PRODUCTS AND SERVICES AVAILABLE FROM THE EARTH OBSERVATIONS COMMUNITY. 2.LINKS WOULD BE BUILT WITH OTHER COMMUNITIES THAT HAVE NEED OF, OR CONTRIBUTE TO, WATER CYCLE INFORMATION. 3. STATEMENTS OF PRIORITIES FOR GEO, SPACE AGENCIES AND THE EARTH OBSERVATION COMMUNITY WOULD COORDINATED AND COHERENT. 4.THE NEEDS OF SEVERAL WATER PROGRAMS (E.G., IGWCO) WOULD BE SERVED AS WELL AS GEO BY BRINGING TOGETHER USERS AND DATA PROVIDERS IN THE WATER SECTOR.

9. LINKS TO OTHER SOCIETAL BENEFIT AREAS CLIMATE: FEEDBACKS FROM WATER VAPOR, CLOUDS AND LAND SURFACE FLUXES ARE THE MAJOR UNCERTAINTIES IN CLIMATE CHANGE PROJECTIONS. WEATHER: PRECIPITATION AND CLOUD PREDICTION ARE PRIMARY FORECAST VARIABLES THAT NEED THE SUPPORT OF THE OBSERVATIONAL PROGRAMS. Uncertainty of Climate Predictions Annual Precipitation (Hadley and Max Planck Climate Models, 2070s, A2 Scenario)

10. AGRICULTURE: WATER IS A CRITICAL CONTRIBUTOR TO AGRICULTURAL PRODUCTIVITY. ENERGY: THE WATER AND ENERGY CYCLE OF THE ATMOSPHERE CONTROL MOST OF THE SOURCES OF RENEWABLE ENERGY (CLOUDS-SOLAR; WIND-WIND; WATER-HYDRO)

11. HEALTH: WATER BORNE DISEASES AND DISEASE CAUSED BY THE LACK OF CLEAN WATER ARE A MAJOR CAUSE OF MORTALITY IN THE DEVELOPING WORLD. ECOSYSTEMS: MINIMUM REQUIREMENTS FOR WATER EXIST FOR ALL ECOSYSTEMS. INFORMATION IS NEEDED TO ADVISE ON WATER STRESS AND ON THE DEGREE TO WHICH LONG-TERM NEEDS CAN BE MET. THIS CONNECTION DOES NOT REPLACE THE IMPORTANT WORK OF THE WATER AND HEALTH COMMUNITY OF PRACTICE, BUT IT ONLY PROVIDES THE CONTEXT WITHIN THE WATER SECTOR FOR DEALING WITH REQUESTS FROM THE WATER AND HEALTH CP. (PFRA?)

12. DISASTERS: WATER CYCLE DISASTERS (FLOODS AND DROUGHTS) REQUIRE ACCESS TO IMPROVED FLOOD FORECAST AND MONITORING SERVICES. BIODIVERSITY: TRENDS IN BIODIVERSITY ARE SENSITIVE TO TRENDS IN WATER QUALITY AND CHANGES IN WATER QUANTITY.

BUT WHAT DO THE USERS THINK? WE NEED A WATER CYCLE CP TO ADVISE.

14. WATER CYCLE MEASUREMENTS WILL HAVE GLOBAL BENEFITS IF DEVELOPING COUNTRIES GAIN THE CAPABILITY OF USING THESE DATA (C apacity Building – Technology, Education/Training and Field Applications) - Developing nations should be provided with the hardware and software to access all IGWCO data products and forecasts. - Training materials should be developed and sessions carried out in developing countries. THE WATER CYCLE COMMUNITY OF PRACTICE COULD PROVIDE A MORE COMPREHENSIVE APPROACH TO CAPACITY BUILDING. + =

19. TIMELINE FOR DEVELOPMENT DECEMBER 2006: COMPLETE THE FIRST DRAFT OF THE CP PLAN FEBRUARY 2007: ESTABLISH A CP EXECUTIVE AND A PLANNING COMMITTEE MARCH 2007: FINALIZE THE CP REPORT. APRIL 2007: ESTABLISH A WATER CYCLE CP WEB PAGE SUMMER TO FALL 2007: HOLD A WC CP WORKSHOP/MEETING FALL 2007: INITIATE SEVERAL WATER CYCLE CP PROJECTS, WITH ONE OR TWO IN DEVELOPING COUNTRIES IN COLLABORATION WITH CAPACITY BUILDING EFFORTS.

20. RECOMMENDATIONS: 1. THE UIC ENCOURAGE AND SUPPORT THE FURTHER DEVELOPENT OF THE WC CP. 2. THE UIC RECOGNIZE THE DEVELOPMENT OF THIS CP IN ITS DOCUMENTS. 3.THE UIC PROVIDE COMMENTS ON THE PRIORITIES AND STRUCTURE OF THIS CP AS IT DEVELOPS. ONE LAST THOUGHT: THE WATER CYCLE CP NEEDS A SECRETARIAT. CANADA IS A RECOGNIZED LEADER IN MANY WATER AREAS. WOULD THE CANADIAN GEO SECRETARIAT BE INTERESTED IN BEING THE WC CP SECRETARIAT?
