  1. Climate Change Technology Needs Assessment for Thailand Water Resource Management PorraneeThanapakpawin SurajateBoonya-Aroonnet PintipVajarothai AungkanaPratumthong RoyolChitradon Hydro and Agro Informatics Institute (HAII) Ministry of Science and Technology, Thailand

  2. The changing water situation: Impacts from Climate change • Management challenges • Framework for technology needs assessment • Prioritized adaptation technologies

  3. 1950-1997 average 1,374 mm./year Rainfall has been above average in the past decade Greater inter-annual variability compared to past 3

  4. mm Average200620072008200920102011 (38.7)(58.5) (36.1) (39.3) (80.9) (19.2)(145.7) (mm/month) Greater change of monthly rainfall – timing, location, and intensity (e.g. Season change)

  5. mm Average200620072008200920102011 (174.1) (196.4) (270.5) (204.2) (209.9) (111.0)(212.0) (mm/month)

  6. mm Average200620072008200920102011 (219.2) (244.8) (219.2) (187.6) (197.3) (299.8) (288.8) (mm/month)

  7. mm Average200620072008200920102011 (mm/month) (236.0) (248.7) (233.1) (268.5) (227.2) (222.4)(314.9)

  8. Several areas experience both flood & drought problems Source: Disaster Prevention and Mitigation

  9. Thailand 2011 Flood Photo taken Sep 14, 11: SurajateB.Aroonnet Photo taken Sep 14, 11: SurajateB.Aroonnet Photo: thairath.co.th Photo: Channel 3

  10. El Nino and La Nina alternates more frequently. Expect higher climate variability Source: Climatic Data Center/NESDIS/NOAA

  11. Project increased rainfall ที่มา: IPCC (2551)

  12. Only 6% of rainfall is collected in large reservoirs • High inter-annual reservoir inflow variability (19% nation-wide, 20-30% regionally) • Only 13% of agricultural areas is irrigated

  13. Solve both flood & drought problems together • Build water security for all user sectors • Macro level: Irrigated agriculture, Industry, Urban areas • Micro level: Rain-fed agriculture • Targets of technology needs: • Secure capitol water supply through storage & distribution • Build management flexibility in all climate & demand scenarios • Minimize disaster risks & impacts • Build knowledge/know-how and data 13

  14. The process for technology prioritization Objectives Review possible technologies Technology Group 1 2 3 4 5 6 7 (High Impact) (Low Impact) Multi Criteria Criteria Analyze from output/outcome Analyze from SWOT Funding source Prioritized Technology External funding/ Technology transfer Internal funding Domestic development High Impact High SWOT High/Low Impact Low SWOT

  15. Long-range weather forecast (3-7 months) Flood sensorweb (Event detection, monitoring, and decision support system ) Networking of water infrastructures & management 16

  16. Application of science, technology & innovation • Knowledge management • Capacity & collaborative network building

  17. Accumulating debt decreased from 2.6 million THBto 1.84 million THB in 2009 *collected from 15 households in 2009

  18. Goal of Thailand WRM: Water & agricultural security • Technology needs: Flexible infrastructures & Better management: planning , operation & disaster management • Macro-management: • - Networking of water infrastructures & management • - Long-range weather forecast (3-7 months) • - Flood sensorweb • Micro-management: CWRM as a key risk-based adaptation approach to cope with climate variability & build sustainable agriculture 19

  19. Risk assessment Reservoir networking Water flow network Planning Operation Forecasting/Modeling Network & Clustering Disaster management Survey/observation Telemeter data Remote sensing/GIS Oceanic data Flash flood & landslide warning Users
