Presentation from the 2014 World Water Week in Stockholm www.worldwaterweek.org ©The Author(s), all rights reserved www.siwi.org Water from Space Opportunities and Limitations on the use of EO for Water Management Aleix Serrat-Capdevila, D. Alejandra Garcia, Noosha Tayebi, Luis E. Garcia, Diego Rodriguez, Marcus Wijnen - The World Bank Earth Observations in Support of Sustainable Water Management Stockholm WWW 2014 The Water Partnership Program • Multi-donor trust fund supporting technical assistance and analytical work to bolster project preparation and implementation across all water sub-sectors. • Platform that brings the best knowledge, science, skills, and solutions to match the challenges at hand. • Presently supported by the governments of The Netherlands, United Kingdom, Denmark and Austria. http://water.worldbank.org/wpp The WPP Remote Sensing Initiative Improve quality and effectiveness of WRM. Better serve client countries and enhance impacts of WB water related operations Develop and disseminate a clear picture of Remote Sensing Products and applications: Availability and State of the Art Relevance for solving water problems Evaluation: potential & limitations (joint use, validation) (errors, reliability) The WPP Remote Sensing Initiative A practical, result-oriented approach: – Based on Project Needs and Constraints – Demand Driven – Not to show what technology can do, but what is desirable and will work from an operational point of view. – Emphasis on validation and reliability The WPP Remote Sensing Initiative Portfolio Review Water & RS Diagnosis • Identify opportunities for use of EO for WRM • How can the World Bank better capitalize on EO? Portfolio Review of the WB Water Sector • 775 World Bank projects from 2004-2012 with water sectors or WRM themes as primary or secondary share of the lending. • The sectors encompass a range of water resources activities: Water supply and sanitation – irrigation – hydropower – flood control – environment – management – planning – transboundary issues, etc… The WPP Remote Sensing Initiative Portfolio Review Water & RS Key Data & Information Diagnosis • Identify opportunities for use of EO for WRM • How can the Bank better capitalize on EO? Key Data and Information Needs • From the water sector activities in the portfolio review: key variables and information needs for each activity.

The WPP Remote Sensing Initiative Portfolio Review Water & RS Key Data & Information Windows for RS Assistance Diagnosis • Identify opportunities for use of EO for WRM • How can the Bank better capitalize on EO? “Understanding Water through Space” workshop, 20 world experts (April 2014, The Hague, NL) Potential Applications in the use of EO for Water Management Water allocation planning & reservoir operations • In large poorly-gauged basins (high Tc): Precipitation, ET, Soil Moisture Hydrologic Monitoring & Prediction Water allocation planning & reservoir operations • Snow Cover and Snow Water Equivalent: water availability of snowmelt. Combining RS & in-situ observations & snow models From http://www.nohrsc.noaa.gov/nsa/ Flood Warning • Water level altimetry + hydrodynamic models from http://apps.iwmbd.com/satfor Flood Warning • Caveats & Difficulties of rainfall-runoff Flood Prediction. (errors in rainfall tend to accumulate in flood peak estimates) • Central America Flash Flood Guidance: HydroEstimator Satellite Product & “excess amount of rainfall for a threehour period over what is needed to cause bankfull flows in small streams” Flash Flood Threat Index Irrigation Water Management • ET: detect irrigated extensions and quantify water use: ~Irrigation efficiency: reduce non-productive ET ~Crop water productivity: crop kg per m3 of water ~Verify insurance claims of non access to water • Soil Moisture: Monitor irrigation needs to increase irrigation efficiency • SM & ET & Farm Studies: characterize EO signatures of desirable farming practices. Water - Energy Nexus • ET estimates: monitor impacts of energy subsidies on GW pumping. • RS real-time data for reservoir operations for hydropower production.
